Description

Lautsprecherkorper

Technical field

The present invention relates to a loudspeaker body, in particular a loudspeaker housing, having at least two preferably planar surface elements, in particular outer wall surfaces.

The present invention further relates to a cover or a covering for at least one loudspeaker body, in particular for at least one loudspeaker housing.

State of the art

Loudspeaker bodies or loudspeaker housings generally have the task of fixing an acoustic radiator, which is generally designed as a membrane, and of shading the antiphase components of the sound waves generated by the membrane.

Irrespective of this, loudspeakers are often used for advertising and / or information purposes. The customer's attention is to be increased by the radiated music and / or word information. In this context, it is particularly known for advertising purposes to combine structures such as posters and advertising stands with loudspeakers.

It is often disadvantageous here that the known loudspeaker bodies have a considerable spatial expansion even when not in use and thus a not inconsiderable space requirement arises. This has a particularly disadvantageous effect on loudspeakers with advertising and information stands or structures, which are regularly held in different locations, such as at trade fairs or for promotions should be used and therefore often have to be transported.

In particular, the spatial expansion of the loudspeaker body or loudspeaker housing makes it difficult to transport the advertising and information stands or superstructures effectively, because space-saving storage, for example in the trunk of a person, is not possible , If, to avoid this disadvantage, the use of loudspeakers for advertising and information stands or structures or also for other applications is dispensed with, corresponding information or advertising messages cannot be offered acoustically, at least not through loudspeakers. However, an acoustic presentation is often desirable.

A loudspeaker frame made of paper pulp is known from the publication DE 100 21 257 A1. Such a loudspeaker frame offers the advantage of a relatively low weight, so that this known loudspeaker frame is easy to transport. A disadvantage of this speaker frame is the high space requirement, even when not in use.

Furthermore, the document DE 100 00 283 A1 discloses a collapsible packaging with a miniature reproduction device. The miniature playback device can be activated, for example, by touch and, after it has been activated, acoustically reproduces permanently stored information, for example instructions for use. However, this miniature reproduction device cannot replace the various uses of a loudspeaker.

Speakers are known from the advertising industry which make it possible to place text, images or decorative text on at least one of their side surfaces

Attach or project elements. For example, in the

Document EP 1 053 541 A1 a decorative cover for a sound speaker housing described; this decorative cover serves in particular to protect the acoustic radiators of the loudspeaker.

From the document WO 99/46927 A2 a system for audiovisual information transmission is known, in which images or texts are projected or transmitted onto a screen, this screen surrounding a loudspeaker. In such a system, however, the sound power of the speaker is significantly reduced by the screen surrounding the speaker.

Presentation of the invention: task, solution, advantages

On the basis of the disadvantages and shortcomings set out above, and in consideration of the outlined state of the art, the present invention is based on the object of developing a loudspeaker body, in particular a loudspeaker housing, of the type mentioned at the outset in such a way that the disadvantages discussed above do not occur; in particular, the desired loudspeaker body should be particularly space and space-saving when not in use.

This object is achieved by a loudspeaker body with the features characterized in claim 1. Advantageous refinements and useful developments of the present invention are characterized in the respective subclaims.

According to an embodiment essential to the invention, a folding blank is used to create a spatial body that serves as a loudspeaker housing. Training in the design of the housing

- As a four-sided pyramid, which has folds to fold in at least on two opposite sides, or else

as a triangular cross section, in which only one side has a fold, a folded edge or the like, conceivable to provide a flat folding blank that is easy to assemble.

The use of a cover serves to set up such a loudspeaker, in which the foldable bottom area of the technology can be arranged, freely, for example in a shop, and to attract the customer's attention through the radiated music and / or through the radiated Word information attracts attention.

Since the custom-fit cover covers the housing, the viewer's attention is drawn away from the loudspeaker technology to the cover, which can either contain advertising information or is simply decorative, so that the viewer is positively attuned and listens to the acoustic signal emitted via the loudspeaker , The user can then determine whether this is an advertising message or music to attune to positive buying behavior.

A particular advantage of the loudspeaker body according to the present invention is its small space requirement when not in use. For this purpose, the loudspeaker body in a further development essential to the invention has at least two flat surface elements which are flexibly connected and / or connectable, at least one acoustic radiator, for example in the form of a membrane, being arranged and / or arrangeable on at least one flat surface element and at least two peripheral edges form the plane surface elements a plane; the loudspeaker body can be locked and / or locked on a base plate.

Since at least two flat surface elements are flexibly connected to one another and at least two marginal edges of the flat surface elements form a plane, the two flat surface elements can be brought into a position of use by a user. In its position of use, the loudspeaker body has a support surface or a standing surface due to the edge edges forming a plane and also carries an acoustic radiator. As a result, a loudspeaker housing that is stable on a flat surface is formed.

Unless at least two marginal edges of the flat surface elements form a plane, it is expediently provided that the loudspeaker body is locked on a base plate and thus has a stable balance. It is thereby achieved that the loudspeaker body forms a housing for an acoustic radiator in a position of use.

In this context, the fact that loudspeakers based on the N [e] X [t] T [ransducers] technology, i.e. surface radiators and molded parts with sound radiation, do not need a robust housing for good sound properties, because the membrane breaks, can be exploited oscillates in countless individual vibrations and does not vibrate as a piston as a whole.

Due to the preferred embodiment of the loudspeaker body, the interconnected flat surface elements can be brought into a non-use position due to their flexible connection, for example by folding them over, in which they neither necessarily form a housing capable of acoustic applications nor necessarily carry the acoustic radiator.

In such a non-use position, the individual flat surface elements can be arranged such that they have a very small space requirement, for example by stacking one on top of the other, which corresponds to only a fraction of the space requirement in the use position. This allows the speaker body to be in its non-use position. transport particularly easy.

In a preferred embodiment variant, the acoustic radiator is a surface radiator and / or a molded part with sound radiation, which are based on N [e] X [t] T [ransducers] technology. In the NXT technology, the membrane, which is conventional per se, is designed, for example, as a plate made of rigid foam that can be hung swinging freely.

Almost all materials, for example ceiling cladding, windows, wooden surfaces or the like, can be used as NXT panels or so-called NXT panels. The N [e] X [t] T [ransducers] panel emits sound in the manner of a bipolar radiator both forward and backward, evenly and in phase. Special advantages of the NXT panel are its low weight and its small spatial depth.

In a preferred embodiment variant, one or more of the flat surface elements has at least one recess for receiving at least one N [e] X [t] T [ransducers] panel. However, the loudspeaker body can advantageously also serve to accommodate a conventional loudspeaker chassis.

Furthermore, in an advantageous embodiment of the loudspeaker body, the recess of a surface element corresponds to at least one recess of at least one adjacent or opposite surface element in such a way that, in particular when the loudspeaker body is folded, a cavity for accommodating loudspeaker technology, for example for accommodating at least one NXT -Exciter, is created.

The flat surface elements can preferably consist of plastic, paper and / or cardboard. In this case, two flat surface elements are preferably connected to one another via at least one folded edge connected. Alternatively, two flat surface elements can also be reversibly connected to one another via push buttons, at least one Velcro fastener and / or at least one adhesive connection.

In one embodiment variant it is provided that the loudspeaker body has a base plate which corresponds to the cross section of the connected flat surface elements. This base plate forms the lower end of the speaker body and is preferably made of sound wave insulating material. Furthermore, the base plate can have pedestals, which are preferably also made of sound wave insulating material.

For the use of the loudspeaker body according to the present invention for information and / or advertising purposes, information and / or advertising instructions can be arranged on at least one flat surface element of the loudspeaker body. This information and / or advertising information is preferably designed as a poster, as a decorative element, as a film and / or as a cover.

This embodiment enables the loudspeaker body according to the present invention to be used as an information and / or advertising device which, like an information stand, for example, can deliver both optical and acoustic information to the environment. A cover provided with information and / or advertising preferably corresponds to the shape of the loudspeaker body in its position of use.

The loudspeaker bodies known from the prior art do not give the user the option of interchangeably attaching information or an image to the loudspeaker housing without further aids; in advertising and information events in particular, a loudspeaker housing is often used as an information carrier, the information to be displayed can change rapidly.

This problem is solved in the manner according to the invention by applying a replaceable cover or a replaceable covering to a loudspeaker body, in particular to a loudspeaker housing, of the type set out above. The loudspeaker housing can have a pyramid shape, a cone shape, a cylindrical shape, a box shape or another shape.

The cover or the covering according to the present invention expediently has at least one information and / or advertising notice; For example, the cover or cover is printed with pictures, in particular with pictures of products or pop stars, and / or with text messages.

In an advantageous embodiment of the present invention, the cover or the cover is either formed from one piece or can be assembled by the user himself from several parts.

At least one surface element, in particular at least one wall, of the loudspeaker body advantageously acts as an acoustic radiator or as a sound radiator in order to achieve a particularly high sonic quality.

In order to be able to convey the highest possible visual information content, the surface element, which acts as a sound radiator, is preferably also covered with the cover or with the covering. In this case, the surface element is achieved by so-called EXITERs mounted on the inside [the function of exiters or exciters is based on the to amplify existing harmonics (overtones) in the input signal or to generate additional harmonics].

An advantageous embodiment of the present invention is, for example, a three-dimensional loudspeaker in which at least one surface element, for example at least one outer wall surface, is excited to vibrate, in particular by means of N [e] X [t] T [ransducers] technology, and thus as a sound generator serves.

Advantageously, at least this one surface element is provided with a cover or with a coating, which with the side

- Adhesive, especially when using the same materials, or

- cohesively, especially when using different materials, or - intimately connected in another way. It is hereby achieved that the cover or the cover is so closely connected to the surface element of the loudspeaker that can be excited to vibrate that the cover or the cover itself resonates.

In a particularly advantageous embodiment of the invention, the cover or the cover and the surface element are formed from paper, cardboard or from a composite body (aluminum-paper-foam-paper-aluminum). If a composite body is used, another metal can be used instead of the aluminum. A glass fiber composite body can also be used.

Independently of this or in connection with this, the cover or the covering is formed from a material that is as small as possible

Attenuation, in particular an attenuation of less than about three deci- at, caused. An optimal material causes an attenuation of less than about 0.5 decibels.

In a further advantageous embodiment of the present invention, at least one cover, at least one cover or at least one cover is pulled over a three-dimensional loudspeaker housing body which is equipped with conventional technology in the form of one or more loudspeakers. This cover or the cover expediently has at least one corresponding cutout in order not to hinder the sound radiation by means of the at least one loudspeaker.

Advantageously, the cover or the cover or the cover is “sucked” over the speaker body, that is to say it fits snugly against the arbitrarily shaped speaker body.

In an advantageous embodiment of the present invention, the sound transducer, in particular the loudspeaker, is based on N [e] X [t] T [ransducers] technology (= new flat-membrane loudspeaker technology developed under the leadership of Next Transducers; the loudspeakers can act like a picture the wall are hung, but are not capable of deep bass). In principle, however, the invention is independent of the technology of the loudspeaker.

The acoustic radiator, in particular a sound transducer, is preferably formed from glass, from plastic, from metal, from paper and / or from composite materials. Both a monolithic structure and a sandwich structure are possible.

Best way to carry out the invention

To avoid unnecessary repetitions, the following explanations relate to the designs, features and advantages of the present invention (unless stated otherwise).

- both on all three exemplary embodiments of a loudspeaker body 10 according to the present invention (see FIG. 1; FIGS. 3 to 5; FIG. 6) - and on both exemplary embodiments of a cover 30 according to the present invention (see FIG. 7; FIGS. 6 and 8) )

- As well as both exemplary embodiments of a coating 20 according to the present invention (cf. FIG. 9; FIG. 10).

Figure 1 shows a first embodiment of a speaker body 10 in a perspective view. The loudspeaker body 10 consists of square and triangular planar surface elements 12 made of cardboard. The flat surface elements 12 are connected to one another via folded edges 16. The flat surface elements 12 can be pivoted relative to one another via these folded edges 16.

In contrast to conventional loudspeaker bodies, the loudspeaker Chercher body 10 according to the present invention by the relative mobility of its flat surface elements 12 so deformable or foldable that it takes up a very small volume in a non-use position. This can be done by folding the flat surface elements 12 into one another.

This makes it possible for a user to deform or fold the loudspeaker body 10 from a use position (shown in FIG. 1) into a non-use position (transport position). As a result, the loudspeaker body 10 can be stored and transported very well.

In the position of use, the lower marginal edges 14 form a plane E, so that the (opened) loudspeaker body 10 has a secure stand or a stable balance.

Furthermore, the loudspeaker body 10 has three recesses 24 for receiving an acoustic radiator, the third recess, which is not visible in FIG. 1 for reasons of perspective, being located on the surface element 12 provided on the left in FIG. 1. The three recesses 24 are arranged at the same height with respect to the plane E.

These recesses 24 now correspond to one another in such a way that when the loudspeaker body 10 is folded up (cf. FIGS. 3 to 5 analogously), a receiving volume in the form of a cavity for receiving a N [e] X [t] T [ransducers] exciter or NXT panels 22 in the interior of the loudspeaker body 10.

The formation of the receiving volume or cavity in the interior of the speaker body 10 is favored by the two recesses 24 provided on the left or right surface element 12 in the

Region of the respective middle folded edge 16 are arranged, specifically measured approximately in mirror or axisymmetric with respect to the respective folded edge 16.

Since, furthermore, the recess 24 assigned to the front surface element 12 in FIG. 1 is also arranged symmetrically with respect to this front surface element 12, it results in connection with the technical feature already mentioned that the three recesses 24 are in relation to the plane E are arranged at the same height, even in the folded state of the loudspeaker body 10, a maximum receiving volume for the loudspeaker technology, which is therefore securely received in the cavity formed by the recesses 24.

This reliably prevents the technical area of the loudspeaker body 10 from being pressed, squeezed, compressed or otherwise damaged, in particular when (folded).

Such a loudspeaker body 10 can be used very advantageously for promotional events, such as for trade fairs, because due to its small volume (when not in use), this loudspeaker body 10 can be transported and set up without any problems.

FIG. 2 shows a perspective illustration of a base plate 18. Such a base plate 18 can, for example, consist of cardboard, paper or similar materials and also have flat surface elements 12 '. In this way, the base plate 18 can also be folded together, so that there is a small volume. Furthermore, the base plate 18 has an opening 26. This is provided so that electrical cables can be led from the floor area to the acoustic radiator for its power supply.

Figure 3 shows a second embodiment of an inventive Loudspeaker body 10 in its position of use, the loudspeaker body 10 consisting of six flat surface elements 12. An N [e] X [tjT [ransducers] panel 22 is arranged in one of the flat surface elements 12.

The flat surface elements 12 are unfolded by means of the folded edge 16 in such a way that the loudspeaker body 10 assumes an essentially cuboid shape. The lower edge 14 forms the footprint. The loudspeaker body 10 can now be folded over the folded edges 16 shown as a dashed line. The dimensions of the opposite flat surface elements 12 correspond to one another.

As shown in FIG. 4, the space requirement of the speaker body 10 is reduced by folding over the folded edges 16 (shown as a dashed line).

As shown in Figure 5, the flat surface elements 10 can be completely folded into each other, whereby the loudspeaker body 10 receives a very space-saving design in its non-use position.

The loudspeaker body 10 can be used, for example, in a particularly advantageous manner for trade fairs or for promotional purposes as an advertising stand or as an advertising medium. The loudspeaker body 10 according to the present invention, as shown in FIG. 5, is initially transported in a non-use position (transport position) and can be easily stowed or handled due to its small space requirement.

In order to be able to use the loudspeaker body 10 for advertising purposes, it is unfolded, as shown in FIG. 4, until it reaches the position of use corresponding to FIG. 3. The one completely unfolded Loudspeaker body 10 can be placed securely over the lower edge edges 14 and can now emit acoustic and optical advertising messages to its surroundings.

In Figure 6, a third embodiment of a speaker body 10 is shown in side view. The acoustic radiator 40 of this loudspeaker body 10 is completely formed by one of the surface elements 12, namely by one of the flat outer wall surfaces.

This outer wall surface is detachably connected to a cover 30 (cf. FIG. 6 and FIG. 8), the dimensions of the cover 30 corresponding to the outer dimensions of the loudspeaker body 10 in its position of use.

When using the loudspeaker, the outer wall surface 12 is excited to vibrate by means of N [e] X [t] T [ransducers] technology and thus serves as a sound generator. The outer wall surface 12 is so closely connected to the cover 30 that the cover 30 is also excited to vibrate and resonates with the flat outer wall surface 12. This is visualized in FIG. 6 by an oscillating sign above the cover 30.

The cover 30 and the outer wall surface 12 are formed from the same material, namely from a material which causes a sound attenuation of less than three d [ezi] B [el]. For example, a composite body made of foam, paper and / or aluminum or a glass fiber composite body can be used for the outer wall surface 12 and the cover 30.

In the following, the materials with which N [e] X [t] T [ransducers] -based sound transducers can be created are listed as examples, whereby the list of materials is generally divided into five categories. can be shared, namely paper, plastic, glass, metal and composite material. Both a monolithic structure and a sandwich structure are possible; preferred material thicknesses are two millimeters, three millimeters, five millimeters, six millimeters or ten millimeters.

Preferred materials for the outer wall surface 12 and for the cover 30 can be, for example:

- KAPA Sound Performance (Polyurethane Forne Gore); from KAPA there are also: - KAPA Sound Standard, - KAPA Sound Economy,

- KAPA Sound Ceiling, - KAPA Sound M;

- Nomex honeycomb; - Rohacell Gore Panels;

- decar glass;

- Feited Paper;

- PCB phenolic paper / glasprepeg;

- E-Glas.prepeg on polycarbonate honeycomb; - Polystrene foam core with paper / plastic skin;

- felted paper;

- PCB materials;

- Rohacell core panels;

- Glasprepeg. on Nomex Honeycomb; - Polycarbonate (PC) Aluminum (AI) Nomex Honeycomb Panels;

- Extruded polycarbonates.

To display optical information, the cover 30 can be provided with advertising or other information and can be designed as a poster or as a decorative element, for example as a decorative surface.

FIG. 7 shows a one-piece cover 30 for the loudspeaker body 10 from FIG. 1. In order to prevent the acoustic performance of the loudspeaker body 10 from being impaired by the cover 30, the cover has a recess 38 which surrounds the acoustic radiator 40.

FIG. 9 shows a cover 20 which can be pulled over a loudspeaker body 10, for example, as shown in FIG. 1. For this purpose, the inner dimensions of the cover 20 (corresponding to FIG. 9) correspond to the outer dimensions of the loudspeaker body 10 in its position of use (corresponding to FIG. 1).

This cover 20 has a recess 28 which surrounds the acoustic radiator 40 and covers all four lateral surface elements 12, namely all four outer wall surfaces, of the loudspeaker body 10 from FIG.

FIG. 10 shows a cover 20 for the loudspeaker body 10 from FIG. 6, namely a cover which is pulled over a loudspeaker housing body. This cover 20 differs from the cover 30 (see FIG. 6 and FIG. 8) in that it covers all the outer wall surfaces 12 of the loudspeaker body 10 from FIG. 6.

The invention is not limited to the exemplary embodiments shown here; rather, it is possible to implement and implement further embodiment variants by combining and modifying the means and features mentioned, without leaving the scope of the present invention. LIST OF REFERENCES
