Description

The invention relates to a reusable communication adapter for face masks, in particular mouth and nose protection masks, with at least one fastening device for the detachable and reusable fastening of the communication adapter on different face masks, with a voice detection device for detecting the language of the mask wearer, with a voice output device for outputting the language from the voice detection device detected language outside of the face mask and with a transmission device for transmitting the language from the voice detection device to the voice output device. The invention also relates to a system comprising such a communication adapter and a face mask, in particular a mouth and nose protection mask. In addition, the invention relates to a method for providing such a system by means of a detachable and reconnectable, and therefore reusable, connection of a corresponding communication adapter.

Various face masks are known, which are worn in particular to protect oneself or to protect other people from infection or the like. These face masks can be worn both in the private and professional environment. This type of face mask is typically but not necessarily designed exclusively as a so-called mouth and nose protector. These include, in particular, medical masks, which are known as so-called surgical masks, FFP2, FFP3 or the like. The use of this type of mask has increased significantly in recent times.

Face masks have many benefits, but they can limit communication because the face masks muffle speech, making it harder for other people to hear the person wearing the face mask. This applies all the more when the people communicating with one another are at a significant distance from one another, there is ambient noise, or very precise communication is required. In order to overcome this disadvantage, masks have already been equipped with communication facilities. This is particularly the case for face masks that can be reused very often and are also expensive, as is the case with so-called gas masks for protection against harmful substances. Some of these communication devices are also not permanently installed in the face mask, but are designed as reusable communication adapters. The latter can be arranged in the face mask and include a Bluetooth module. The Bluetooth modules of different face masks can connect to each other if the wearers of the face masks are not too far apart. The Bluetooth modules send the speech recorded in one mask to the Bluetooth module of another mask, where the speech is re-transmitted in headphones. Speech therefore does not have to pass through the face mask in the normal way, as this is done wirelessly via Bluetooth.

Communication adapters for face masks are already out of the DE 694 24 299 T2 and the DE 10 2016 223 182 A1 known. However, the known solutions are not yet satisfactory, since they do not meet all communication requirements and are associated with high costs.

The present invention is therefore based on the object of designing and developing the communication adapter, the system and the method of the type mentioned at the outset and explained in more detail above in such a way that improved communication between people wearing face masks can be provided more cost-effectively.

This object is achieved with a reusable communication adapter according to the preamble of claim 1 in that the speech detection device for detecting the speech of the mask wearer is designed inside the face mask and that the fastening device has at least one hook element for hanging the communication adapter in an upper, side and/or lower Has edge of the face mask.

The communication adapter is reusable in that the communication adapter can be easily connected and disconnected from a face mask. Thus, the connection between the face mask and the communication adapter is reconnectable to one or more face masks in sequence. This is particularly important in the context of face masks that are intended for single use. This is the case, for example, with many mouth and nose protection masks, especially medical ones. The user therefore only needs a single communication adapter and can use it again and again with different face masks. For this purpose, the communication adapter can be connected to the face mask by means of at least one fastening device. In addition, the communication device includes a speech detection device with which the speech of the mask wearer can be detected. In particular, the language is not through the mask damped and can thus be fully recorded. The only thing to consider is that the sound of the speech can be changed by the mask in front of the mask wearer's mouth. In principle, however, this is tolerable.

A voice output device for outputting the voice detected by the voice detection device is provided outside the face mask connected to the communication adapter. Thus, the output of the voice is only affected to a limited extent by wearing the face mask, since the voice that is output is no longer dampened by the face mask. People can therefore easily and reliably understand the mask wearer if they come sufficiently close to the mask wearer. Since the voice output device can be equipped with an amplifier unit, the people can, if necessary, move even further apart than would be the case without face masks and communication adapters. In order to transfer the speech from the speech detection device to the speech output device, a corresponding transmission device is provided for transmitting the speech or the speech signals. The transmission device therefore takes over the transport of the voice to the voice output device on the outside of the face mask, if necessary through the actual face mask. Since this transmission takes place electronically and not by means of sound waves, as would be the case without the communication adapter, the face mask no longer represents a significant barrier to speech Converts voice signal, which is then transported via the transmission device to the voice output device. The electrical voice signal can then be amplified in the voice output device and output again as voice via at least one loudspeaker of the voice output device.

The stated object is also achieved according to claim 11 by a system comprising a communication adapter according to one of claims 1 to 10 and a face mask, in particular a mouth and nose protection mask, wherein the communication adapter is connected to the face mask with at least one fastening device in a detachable and reusable manner, wherein a voice detection device is provided for detecting the speech of the mask wearer and wherein a voice output device for outputting the language detected by the voice detection device is arranged outside the face mask and that the voice detection device and the voice output device are connected via a transmission device for transmitting the speech.

The advantages of the reusable communication adapter for face masks therefore come into play when the communication adapter forms a common system with a face mask, which is used only once if necessary and then disposed of and replaced with a new face mask. To form the corresponding system, the communication adapter is connected to the face mask in a detachable and reusable manner with at least one fastening device. A reconnectability with one or more masks can thus be provided. In this connected position of the communication adapter and the face mask, the speech detection device for detecting the speech of the mask wearer is provided and arranged such that the speech detection device can detect the speech of the user in an expedient manner. The speech is reliably detected and converted into an electrical speech signal, which is forwarded via a transmission device from the speech detection device to the voice output device, which is located outside the face mask, so that the mask wearer can be easily and reliably understood by bystanders.

Furthermore, the aforementioned object is also achieved according to claim 15 by a method for providing a system according to one of claims 11 to 14, by detachably and reconnectably connecting the communication adapter according to one of claims 1 to 10 to a face mask, in particular a mouth and nose protector - Mask in which at least one hook element of the communication adapter is guided around an edge of the face mask from the outside inwards, in particular bent over, and/or the face mask is clamped at least in sections between at least one magnet of the communication adapter and a magnetic counterpart and/or the face mask is at least is partially connected to a Velcro element of the communication adapter and / or the face mask is at least partially connected via at least one screw connection of the communication adapter with the communication adapter and / or the face mask at least abschnittwe ise is connected to at least one clip of the communication adapter and/or the face mask is connected to the communication adapter at least in sections via at least one push button.

In order to connect the communication adapter to the face mask, at least one hook element of the communication adapter can be passed around an edge of the face mask from the outside inwards. This can be done in such a way that the hook element is bent at the appropriate point from the outside relative to the face mask inward relative to the face mask. In this way, when connecting the communication adapter to the face mask, the respective dimensions of the face mask can be taken into account without any problems. This ensures a good fit and good function of the communication adapter. Alternatively or additionally, the face mask can be clamped at least in sections between at least one magnet of the communication adapter and a magnetic counterpart. For example, the voice output device can include a magnet and a corresponding counterpart, such as a small metal plate, can be positioned in the mask. Attracted by the magnet, the magnetic mate clamps the face mask between the magnetic mate and the magnet. It goes without saying that the magnetic counterpart itself can be magnetic, but does not have to be.

In addition or as an alternative, the face mask can also be connected at least in sections to a hook-and-loop fastener element of the communication adapter. Either the face mask is made in sections from a material that is suitable for joining a Velcro connection, or a separate, corresponding material is attached to the face mask, which can then be connected to the Velcro element of the communication adapter. Alternatively or additionally, the face mask can also be connected to the communication adapter at least in sections via at least one screw connection of the communication adapter. The face mask only has to have an opening through which a screw can be inserted. Therefore, in this context only face masks that are prefabricated in a certain way or such face masks through which a screw can be inserted without significant destruction of the face mask come into consideration. If the communication adapter has at least one clip, the face mask can alternatively or additionally also be connected at least in sections to the communication adapter via the clip by means of clamping or a positive fit.

Alternatively or additionally, the face mask can also be connected to the communication adapter by means of a push button. A part of the push button is then provided on the face mask and the corresponding counterpart of the push button is provided on the communication adapter. The two parts of the snap fastener are then connected to one another in a latching and form-fitting manner. The part of the push button provided on the face mask can be formed from two individual parts which are riveted together and clamp the material of the face mask. The corresponding part can already be attached to the face mask in a pre-assembled manner or can be connected to the face mask by the mask wearer as required. The snap connection between the face mask and the communications adapter is then preferably joined on the outside of the face mask so that the communications adapter is held on the outside of the face mask.

In order to avoid unnecessary repetition and for the sake of better understanding, the reusable communication adapter, the system and the method are described together below without distinguishing in detail between the reusable communication adapter, the system and the method in each case. For the person skilled in the art, however, it is clear from the context which features are particularly preferred for the reusable communication adapter, the system and the method.

In the case of the reusable communication adapter, the speech detection device is designed to detect the speech of the mask wearer within the face mask. In this way, the speech of the mask wearer can be recorded easily and with good quality and then transmitted from the inside of the face mask to the outside of the face mask, where the recorded speech can be output again via the voice output device without being impaired by the face mask. However, the speech of the mask wearer can also be recorded, for example, by a so-called bone sound microphone, which can also be referred to as a bone or cheekbone microphone. Then the face mask in front of the mask wearer's mouth or possible ambient noise cannot significantly impair the detection of the mask wearer's speech. In the case of a bone conduction microphone, it is also possible to dispense with the recording of speech within the face mask. The bone conduction microphone can be pressed against the head, for example in the area of the temples or cheekbones, in order to record sound conducted through bones, whereby background noise can be filtered out digitally. Capturing the speech of the mask wearer inside or outside the face mask but also be possible without any problems through other suitable applications, although it can depend on the respective circumstances of the individual case.

Irrespective of this, the fastening device has at least one hook element for hanging the communication adapter in an edge of the face mask. In this way, the communication adapter can be connected to the face mask quickly, easily and reliably. In this case, the connection between the communication adapter and the face mask becomes more stable and reliable if at least two hook elements, in particular at least three hook elements, are used.

If the fastening device has at least one magnet for detachably and reusably clamping a part of the face mask between the magnet and a magnetic counterpart, the communication adapter can alternatively or additionally be fixed not only on the edge of the face mask. The magnetic counterpart can itself be magnetic or, for example, in the case of a simple piece of metal, it can also be non-magnetic. A similar advantage can be achieved if the fastening device comprises at least one hook and loop fastener element for detachable and reusable connection to a part of the face mask. A magnetic counterpart that could possibly be lost can then be dispensed with. This is particularly easy if the face mask can be connected to the Velcro element of the communication adapter without further conditioning. Otherwise a separate piece of material must be provided on the face mask suitable for connection to the Velcro element of the communication adapter. However, this can already be done in advance during the manufacture of the face mask.

In an alternative or additional configuration, the fastening device can also have at least one screw connection for the detachable and reusable connection to a part of the face mask. The face mask can be a joining partner of the screw connection. However, it is also sufficient if the face mask is held clamped on the communication adapter by the screw connection, which is part of the communication adapter. However, it is also conceivable that the fastening device has at least one clip to which the face mask can then be connected in a detachable and reusable manner. This can be achieved, for example, by a form fit or a clamped connection.

Alternatively or additionally, the fastening device can also have a part of at least one push button, with which the communication adapter can be detachably and reconnectably connected to a part of the face mask by a corresponding counterpart of the at least one push button. The two corresponding parts of the snap fastener can then be connected to one another in a latching and form-fitting manner. The part of the push button provided on the face mask can be formed from two individual parts which are riveted together and clamp the material of the face mask. The snap connection between the face mask and the communications adapter is then preferably joined on the outside of the face mask so that the communications adapter is held on the outside of the face mask.

The aforementioned reusable connections, which may allow the communication adapter to be reconnected to one or more face masks in sequence, allow the communication adapter to be reused multiple times. Therefore, since the communication adapter is not tied to a single face mask, the communication adapter can be used inexpensively.

If at least one hook element is used, this at least one hook element can be provided for hanging the communication adapter in an upper edge of the face mask. However, at least one hook element can also be hooked into a lateral edge and/or the lower edge of the face mask. In this way, the communication adapter is simply and reliably attached to the face mask. It goes without saying that this enables even better results if the communication adapter is connected to a plurality of edges of the face mask and/or to at least one edge of the face mask with a plurality of hook elements, for example at least two or at least three hook elements.

In order to hang a hook element in an edge of the face mask, it is advisable if the at least one hook element is bendable at least in sections. Thus the shape of the hook element can be adapted to the type and/or size of the face mask. A particularly high degree of flexibility with regard to different face masks is achieved here if the at least one hook element is designed to be adjustable from a stretched orientation, if necessary at least straight, to a bent orientation encompassing the edge of the face mask from the outside inwards and back. The hook element can then initially in about straight line alignment and then brought to the appropriate face mask. Where the edge of the face mask is, the hook member can then simply be bent over into the crimped orientation, embracing the face mask from the outside in, to achieve a perfect fit on the face mask.

The at least one hook element can have an antibacterial coating so that the communication adapter can be reused several times without any problems and without the communication adapter having to be cleaned in a time-consuming manner in between. This effect can be achieved easily and effectively if the coating comprises aluminium, copper and/or titanium dioxide.

If the speech detection device is provided on at least one free end of the at least one hook element for arrangement within the face mask, it can be easily introduced into the interior of the mask. In addition, the speech detector can also be easily positioned in a suitable position on the inside of the face mask. In this case, the corresponding hook element can also assume a fastening function for fastening the communication adapter to the face mask in order to achieve a corresponding synergy. However, this is not necessary. Alternatively or additionally, a synergy can also be used in such a way that the transmission device for transmitting the speech is at least partially integrated into the at least one hook element carrying the speech detection device. Thus, the communication adapter can be made more compact and lighter.

For reasons of cost, it can be advisable if the transmission device is provided exclusively with a cable connection. This is also very reliable. However, in order to avoid a corresponding physical connection, to save weight, to simplify the construction of the communication adapter and/or to be able to bridge greater distances to the listener, the transmission device can also be provided in a radio-bound manner, at least in sections. In this case, transmission via Bluetooth is a good option, since inexpensive standardized components can be used here. In principle, the non-wired transmission device can be integrated into the voice detection device itself.

So that the speech detection device can reliably record the speech of the mask wearer, it is expedient if the speech detection device can be displaced at least partially and in sections in the longitudinal direction of the at least one hook element relative to the at least one hook element. Then the speech detection device can be arranged on the inside of the face mask close enough to the mouth of the mask wearer and at the same time far enough away from it. In this way, speech can be captured well without being affected by breathing noises.

If support loops and/or support brackets are provided, which the mask wearer can pull over his ears, the communication adapter can, if necessary, be hung at least essentially on the user's ears. This can prevent the face mask from slipping due to the weight of the communication adapter. However, an additional connection between the communication adapter and the face mask will be expedient in many cases in order to ensure suitable positioning of the voice detection device on the inside of the face mask and thus reliable communication. This additional connection between the communication adapter and the face mask can be achieved, for example, by a hook element on which the voice detection device is also arranged.

Irrespective of this, a speech detection device, for example in the form of a bone sound microphone, can also be attached to the support loop or a support bracket. The bone conduction microphone could be provided in a simple and integrated manner on a temple or cheek of the mask wearer.

In order to be able to limit the capacity of the battery or accumulator and thus the weight of the communication adapter, it may be advisable to provide an on/off switch and/or a volume control. In this way, an unnecessary power consumption can namely be avoided. For reasons of simple handling of the communication adapter, it makes sense if the switch and/or the controller are provided on the voice output device.

If the mask wearer has to communicate with a larger group of people at the same time or has to communicate over a longer distance, the listener or listeners may have problems understanding. This is the case, for example, if the speech of the mask wearer has to be transmitted to such an extent that it reaches the listener or not all listeners with sufficient volume. Then either the volume can be increased or, if necessary, the voice output device can be removed from the rest of the communication adaptor ters to be separated. This is particularly easy if the transmission device is designed to be radio-based, at least in sections. The voice signal can then be easily transmitted to the voice output device, even if the voice output device is not attached directly to the face mask. Rather, the speech output device can be removed and brought to a location that is close enough to the listener or listeners so that he/she/they can understand the mask wearer without any problems.

The voice output device can therefore preferably be connected to other parts of the communication adapter in a detachable and reconnectable manner. Then the voice output device can be separated from the corresponding parts and then reconnected to these parts. If necessary, these parts can correspond to the other parts of the communication adapter. The remainder of the communication adapter can then remain on the face mask and only the voice output device can be brought closer to the listener or listeners. So that the voice output device can be easily and quickly separated from other parts of the communication adapter and reconnected to these parts, a screw connection, a Velcro connection, a plug connection, a push button connection and/or a magnetic connection is particularly suitable.

In a first particularly preferred embodiment of the system, at least one hook element of the communication adapter is routed around an edge of the face mask from the outside inwards. This can be achieved particularly expediently by bending the hook element at the appropriate point. In any case, the communication adapter can be easily attached to the face mask from the outside. Alternatively or additionally, the face mask can be clamped at least in sections between at least one magnet of the communication adapter and a magnetic counterpart. The magnetic counterpart is then provided in the face mask or on the inside of the face mask. For simplicity and cost reasons, the magnetic counterpart is not itself magnetic. It is sufficient if the magnetic counterpart is attracted by the magnet of the communication adapter. Alternatively or additionally, the face mask can be connected at least in sections to a hook-and-loop fastener element of the communication adapter. The face mask is either suitable for this anyway or the face mask must be enabled with a corresponding Velcro counterpart.

The face mask can be connected to the communication adapter very firmly and in a defined manner, at least in sections, via at least one screw connection of the communication adapter. In this case, for example, the screw can be provided on the outside of the face mask or the screw can be inserted through the face mask without significantly impairing the function of the face mask. It can be particularly simple but less defined to connect the face mask at least in sections to at least one clip of the communication adapter. The corresponding connection can be positive or non-positive. Alternatively or additionally, the communication adapter can be reliably attached to the face mask if the face mask is connected to the communication adapter in a detachable and reconnectable manner via a push button. The snap has a mating partner provided on the face mask and a mating partner provided on the communication adapter. Both joining partners then form the snap fastener together, especially when connected.

A simple connection of the communication adapter to the face mask can be achieved if at least one hook element is hooked into at least one side edge, the top edge and/or the bottom edge of the face mask. This can also be done easily and reliably if the at least one hook element is bent at least in sections around the corresponding edge of the face mask from the outside inwards. Alternatively or additionally, a corresponding hanging in of at least one hook element is preferred if the voice detection device is provided on the hook element in order to easily position it on the inside of the face mask near the mouth of the mask wearer.

In a first particularly preferred embodiment of the method, the at least one hook element, which the voice detection device can have, is hooked into at least one lateral edge, into the upper edge and/or the lower edge of the face mask. This is implemented easily and with precise positioning by bending the at least one hook element, if necessary, at least in sections around the corresponding edge of the face mask from the outside inwards.

The invention is explained in more detail below with reference to a drawing that merely shows an exemplary embodiment. In the drawing shows

• 1 a system according to the invention worn by a user comprising a communication adapter and a face mask in a side view,
• 2A-D the communication adapter 1 in a perspective view, a side view, a front view and a view from above,
• 3 the communication adapter 1 in an exploded view and
• 4A-B the system off 1 in perspective views from outside and inside.

In the 1 a user B of a face mask 1 or the mask wearer is shown in a side view. In addition to the face mask 1, which is designed as a mouth and nose protector, user B also wears a communication adapter 2. Together with the face mask 1, the communication adapter 2 forms a system 3 for transmitting speech from the mask wearer while at the same time maintaining the function of the face mask 1 The illustrated face mask 1, which is preferred in this respect, is a mouth and nose protector for one-time use or, at most, for a short period of time. The communication adapter 2, on the other hand, can be reused many times over a long period of time. For this reason, the communication adapter 2 can be detachably connected to the face mask 1 and can therefore also be separated from the face mask 1 again without any problems.

As is well known, the face mask 1 is attached to the ears of the user B by means of elastic loops 4 and is thus held in front of the user B's mouth and nose. The illustrated and preferred communication adapter 2 is also attached to the ears of the user B via support loops 5, which can also be elastic. Instead of the support loops 5, however, support brackets similar to glasses could also be provided. It would also be conceivable if the support loops 5 or support brackets were dispensed with altogether, for example because the communication adapter 2 is held securely and comfortably on the face mask 1 in some other way. In the case of the communication adapter 2 shown and in this respect preferred, a fastening device 6 is provided for fastening to the face mask 1, which in addition to the support loops 5 also comprises hook elements 7-10, with which the communication adapter 2 can be hung on the edges of the face mask 11-14 or attached to the face mask 1 .can be hooked into the face mask 1. The communication adapter 2 attached to the face mask 1 in this way has a voice output device 15 at its front end approximately in the area of the mouth of the user B, which outputs the speech of the user B detected by the communication adapter 2, so that the user B, despite wearing the face mask 1 can be well understood by the listener or listeners. For this purpose, the voice output device 15 that is shown and is preferred in this respect has a loudspeaker 16 .

In the 2A-D the communication adapter 2 is shown without the face mask 1 for the sake of clarity. In addition to the two support loops 5 for the ears of the user B, this communication adapter 2 also has a total of four hook elements 7-10. Two of these hook elements 8, 9 are arranged in such a way that they can be hooked into the upper edge 11 of the face mask 1 in the area of the nose. The two remaining hook elements 7, 10 are connected to the support loops 5 and are intended to be hung in opposite edges 12, 14 of the face mask 1. For the sake of simplicity, the support loops 5 can be pushed into the bent area 17 of the corresponding hook elements 7, 10 and held there in a correspondingly form-fitting manner. However, a permanent connection of the support loops 5 is also possible.

All of the hook elements 7-10 shown are designed to be bendable, so that the hook elements 7-10 are initially brought into a stretched orientation, if necessary at least essentially straight, and then, depending on the size of the face mask 1, in the edge area of the face mask 1 from the outside inwards a bent alignment can be bent. This is in the 2D indicated by the double arrows. A voice detection device 18 is provided on one of the hook elements 7 bent inwardly into the face mask 1 around a lateral edge 12 of the face mask 1 . For the sake of simplicity, the speech detection device 18 is assigned at least essentially to the free end 19 of the corresponding hook element 7 .

Alternatively, a voice detection device could also be provided in the form of a bone conduction microphone, which, if required, is arranged on the side of the face mask on the user's temple or cheek. The voice detection device could then be attached to the support loop or the support bracket of the communication adapter, in particular captively, in order to provide a one-piece configuration of the communication adapter, if this is desired.

So that the speech of the user B can be recorded in a particularly expedient manner, the voice detection device 18 that is shown and is preferred in this respect is at least partially along the length of the hook element 7 slidably attached to the hook element 7, which is also shown in 2D is illustrated by a double arrow. The speech detection device 18 can thus be adjusted to a suitable position in relation to the mouth of the user B of the face mask 1. So that the voice detection device 18 cannot accidentally get lost, the free end 19 of the corresponding hook element 7 is provided with a protective cap 20, which acts as a stop for the voice detection device 18 and thus prevents the voice detection device 18 from being accidentally pulled off or slipping out of the free end 19 of the corresponding Hook element 7 prevented.

The speech detection device 18 detects the speech of the user B within the face mask 1, not shown, and then transmits the speech of the user B or the corresponding speech signal via a transmission device 21 to the speech output device 15. This takes place in the transmission device 21 of the communication adapter 2 that is shown and is preferred in this respect not wired, but at least in sections via radio, specifically via a Bluetooth connection in the case of the illustrated and preferred communication adapter 2. The speech signal or radio signal is then converted back into speech by the speech output device 18 and output via the loudspeaker 16 of the speech output device 15 to the outside in relation to the face mask 1 .

In order to be able to adjust the voice output via the voice output device 15 to ambient noise or the spatial distance between the user B or the mask wearer and the at least one listener, the voice output device 15 that is shown and is preferred in this respect includes a volume control 22. This can therefore be easily controlled by the user B of the face mask 1 to use. The illustrated voice output device 15 also includes a battery or an accumulator whose service life can be increased if the voice output device 15 is activated via an on/off switch 23 if necessary and deactivated again when the voice output device 15 is not required.

The fastening device 6 of the communication adapter 2 can have at least one further fastening means with which the communication adapter 2 can be fastened to the face mask 1 in the area of the voice output device 15 . The voice output device 15 is provided in the illustrated and to this extent preferred embodiment at a position facing away from the mouth of the user B outside the face mask 1 . In general, the voice output device 15 is arranged in a front area of the face mask 1 on the outside thereof. Different fastening means can be used for fastening. A magnetic connection 24 is provided in the communication adapter 2 that is shown and is preferred in this regard. In the area of the voice output device 15, the communication adapter 2 includes a magnet 25 and a magnetic counterpart 26 in the form of a small metal plate. The magnetic mate 26 can be removed from the communications adapter 2 and placed on the inside of the face mask 1 where the magnetic mate 26 is attracted to the magnet 25, thereby allowing the material of the face mask 1 to be pinched between the magnetic mate 26 and the rest of the communications adapter 2.

In the 3 the communication adapter 2 is shown in an exploded view. The base element 27 of the communication adapter 2 is formed by a receptacle 28 for the voice output device 15 and the hook elements 7-10 of the fastening device 6. This base element 27 is made of plastic in the communication adapter 2 that is shown and is preferred in this respect. A support loop 5 is suspended in each of the two hook elements 7, 10 located on the side. The voice detection device 18 , the transmission device 21 and the protective cap 20 are also pushed onto one of these hook elements 7 . The magnet 25 for attracting the magnetic counterpart 26 is provided in the area of the receptacle 28 for the voice output device 15 and the magnetic counterpart 26 is provided relative to this on the inside of the receptacle 28 . The voice output device 15 that is shown and is preferred in this respect is provided in a detachable and reconnectable manner via a screw connection 29 on the receptacle of the communication adapter 2 . The voice output device 15 shown has an internal thread 30 and the accommodation of a corresponding external thread 31 . Alternatively, the connection between the voice output device 15 and the rest of the communication adapter 2 could also be realized via a Velcro connection, a clip, a push button or a magnetic connection.

In the 4A-B the communication adapter 2 is shown together with a face mask 1, the hook elements 7-10 of the communication adapter 2 being folded over the edges 11,12,14 of the face mask 1. As a result, the voice output device 15 is located approximately at the front end of the face mask 1 and on the outside thereof, while the voice detection device 18 is arranged on the inside of the face mask 1, specifically slightly off-centre to the side shifted.
