Glasses holder for small electroacoustic transducers

The object of the innovation is a glasses holder for small electroacoustic transducers, in particular for magnetic, piezoelectric or electrodynamic Converter that can be used as a listener and "or or as a microphone, the converter or its housing is connected to a support device that can be hung on the temple arm.

It is already known to place the electroacoustic transducer in the free end part which has been expanded to form a housing of a temple and to conduct the sound from there by means of a tube into the ear of the user. Such devices are known as "hearing glasses" and are usually used in conjunction with a Amplifier, also built into the temple, is used as a hearing aid for the hard of hearing. Such devices are

only suitable for a specific user and provide This is a special case for the demands that are made today of high-quality transmission in particular of music, there is no indication whatsoever.

According to another proposal aimed at providing high quality music transmission without the troublesome To achieve pressure of a headphone hanger, glasses were created whose temples in the usual way rest on the ear, but have another set of ports, at the free end of which is an electroacoustic one Transducer is arranged, which comes to lie in close proximity to the ear when the glasses are put on. Here acts it is a special device, which is because of the greater effort or because of the eyes of a certain user fitted spectacle lenses cannot easily be used by others. Bs was known at this Hearing glasses also provided to arrange the transducer or the support arm for the transducer removable, but this by means of expensive mechanical means took place.

The innovation has set itself the goal of high quality transmission using headphones to enable, with neither a headphone hanger nor a special design of a spectacle frame is required, so that it can be used without restriction results for everyone, if only

any glasses for normal sighted people, "for example sunglasses are available.

In particular, the innovation is a glasses holder for small electroacoustic transducers, especially for magnetic, piezoelectric or dynamic transducers that are used as listeners and / or as Microphone can be used, the transducer or its housing with one that can be hung on the temple Carrying device is connected, which glasses holder is characterized according to the innovation that the support device consists of a strip-shaped element, which at its end facing away from the transducer carries a U-shaped, upwardly open port set, to which a second, at a distance in the direction of the transducer, facing downwardly open U-shaped port set.

According to a further feature of the innovation, the strip-shaped element can be made of flexible, shape-retaining Material exist so that by simply bending the electroacoustic transducer into its most favorable position can be brought to the ear. In order not to stress the flexibility of the material too much, it may be useful according to a further feature of the innovation, the strip-shaped support element not from one Piece, but to manufacture from two or more parts that are connected to each other by means of a simple joint are pivotally connected. Pur den Pail that that

strip-shaped support element or the transducer of any Basically, the connection between V / andler and support element is provided according to the innovation train detachable.

On the basis of what has been said so far, it follows that the eyeglass holder according to the invention is for one electroacoustic small wa. about one preferably is made of sheet metal or plastic lever-like part, which consists of a with the · eyeglass temple parallel arm and an arm carrying the transducer. The arm resting on the temple is attached to the temple by means of two U-shaped extensions, whereby it is affected by the weight of the Converter is sufficiently set on the other lever arm.

First and foremost, it is the purpose of the innovation, a convenient attachment of the hearing device by bare To enable latching on the temple of glasses. However, this does not rule out the possibility of the renewal Spectacle holder arranged transducer can also be used as a microphone, since it is only necessary, for example transducer used on the left ear as a listener by means of the To put the new, appropriate carrying device on the right temple arm, whereby the converter is now on the Face level protrudes and can easily be brought into the vicinity of the mouth by suitable bending of the neck can.

When using two identically designed support elements, one for the listener, the other for the microphone can be used, so that there is a lightweight headset that is hardly comfortable to use can be outbid.

The acquisition of two identical strip-shaped Support elements can be circumvented in that that support element whose transducer is used as a microphone should, offset by 180 °, be attached to the inside of the bracket.

Further advantages and features of the innovation can be found in the following description with reference to the drawing can be taken from the in

Pig.i in axonometric representation a first embodiment shows the new glasses holder for small electroacoustic transducers, Pig.2 has a further development of the same as its subject matter and Pig.3 finally connects the holder according to the innovation with a commercially available. Can recognize glasses frame.

As Figure 1 shows, there is the innovation according to Glasses holder in the example shown made of a strip-shaped material, for example from a sheet metal strip, which is composed in one piece of two arms 1 and 7 enclosing an obtuse angle. At the

The free end of the arm 7 is the electroacoustic ^ small converter 4 expediently fastened interchangeably, for example by a plug-in or screw connection. On the side facing the ear, the transducer 4 or its housing is provided with a soft cushion 10, e.g. made of an expediently attachable open-pore foam, provided, which ensures a sufficiently tight connection between the ear and the transducer. The arm 1 has on his free end and at a distance therefrom in the direction of the transducer opposite U-shaped extensions 2,3 which expediently first punched in one piece with the sheet metal strip 1,7 as a flap and in another The U-shape.

In contrast to the embodiment shown in Figure 1, which is referred to as a one-piece carrier can be, shows the embodiment shown in Figure 2 only in plan view a two-part Support arm, consisting of part 1 with the two U-shaped extensions 2 and 3 and one pivotable by means of the joint 8 arranged arm 9, which carries the transducer 4 at its free end. The length of the arm 9 is here like this dimensioned that the arm 1 in the pivoted state (arrows e, f) is entirely within the outline of the arm 9 is located. This is a particularly small, space-saving construction.

The practical application of the innovation is shown in Fig.3. A

analog carrying device be arranged.

It can be clearly seen that the support device according to the invention represents a lever whose one-sided Load is given by the transducer 4 and possibly by the train on the handset cord 5. The two U-shaped In this case, extensions form the supports, the forces exerted acting in the same direction as the renewal support device is placed on the temple arm. In Fig.3 are the directions with the arrows a and b. The carrying device is used to put it on for the converter at an angle applied to the temple 6 and rotated in the direction of arrows a, b until the two extensions 2, 3 rest with the connecting web on the temple. Of course, only one ear is enough for one-eared hearing a transducer on one temple, while the other temple remains free.

If the glasses are put on and the holder is moved lengthways along the temple, until the transducer 4 rests on the ear, then the correct fit is guaranteed. Slight differences can be seen compensate by bending the sheet metal strip from which the device is made. But it can also go through Latching in the right place of the temple from the start produces the best le of the transducer.

To use the small converter as a

The support arm for the transducer 4 is on the microphone
opposing eyeglass temple placed in the same manner described above, the transducer then protruding above the plane of the face. If necessary, if the distance from the mouth should be too great, a carrying device according to the invention with a particularly long arm can be used, with the
Arm is bent so far that the microphone comes to lie directly in front of the mouth or just to the side of it.

If necessary, the arm that carries the transducer can also be made extendable so that a universal usability of the innovation according to the spectacle holder for small electroacoustic transducers results.
