DETAILED DESCRIPTION OF THE INVENTION

[0056] FIG. 1 shows the basis of the integrated converter according to the invention is the flat support structure (converter basket) 1, with webs and air passages 10, the number of which should correspond to a prime number, mounted in this is the magnet system, consisting of at least one magnetic yoke 14, a permanent magnet 11, a pole plate 4 and a pole core formed by the yoke 14 of the circumferential copper or pole cap 5.

[0057] In the air gap (formed by the pole plate 4 and copper cap 5) of the magnet system (in the direction of the membrane 2), the voice coil immerses (consisting of the coil carrier 8 and the 2 separate windings 14, 16 with their electrical contacts 25 and 26) which is attached on the underside of the support membrane 24 in the center of the magnet system there is an elastic central guide damper 12 with its webs of air passages 13, the number of which should correspond to a prime number and which is connected in its center to the underside of the membrane 2 via an elastic central damper. Depending on the structure and intended use, it can be advantageous to provide a second circumferential elastic damper 6, which is also connected to the underside of the first membrane and the elastic central guide damper 12.

[0058] While the first membrane 2 is fastened to the flat supporting structure (transducer basket) 1 via an external narrow web via a flat, perforated, radial damper 3, which is located up to the outer edge and has a number of perforated rays that correspond to a prime number if possible.

[0059] And, so that the membrane 2 has a certain flexibility and resonances and modes cannot continue to run outwards and then reflect, there is a circumferential groove 9 outside. The double arrow shows the direction of movement

[0060] Furthermore, it has proven to be advantageous to construct the thin flexible membrane 2, the dampers 6, central dampers 7, central guide dampers 12 and dampers 3 in multiple layers. Foils, nonwovens, fabrics, foams, sandwiches, etc. are particularly suitable for this purpose, which can consist of plastics, metals or natural materials or mixed forms and, depending on the part and purpose, can be adhesive on one or two sides.

[0061] In the hybrid version, FIG. 2 shows that the central guide damper 12 has further permanent magnets in the direction of the membrane 2, namely a rotating magnet 17 (e.g., with the N-S polarity) and a central magnet 20 in the center (e.g., with the S-N polarity),

[0062] and in the area inside the coil carrier 8, e.g., on the underside of the membrane 2, there is a spiral conductor track 18 which is electrically connected in the same direction at the respective end of the winding and is also contacted 27 and 28. Depending on the application, the contact can be made together with the other contacts 26 and 26 but also separately; the double arrow shows the direction of movement.

[0063] Furthermore, at least one elastic, flatter central damper 19, located or provided in this case between the central magnet and the membrane 2, or another circumferential elastic damper is possible.

[0064] A simple integrated version is shown in FIG. 3. Here, the supporting structure (transducer basket) 1 is designed in such a way that it is set back to such an extent that it can be mounted with the supporting structure of the panels etc. (e.g., of a vehicle) 21 so that the front side of the supporting membrane 24 is connected directly or indirectly to the bottom or back of the panel or the cover or the cover layers 22 etc. in such a way that it can produce sound over it.

[0065] A highly integrated version is shown in FIG. 4. Here, the support structure (converter basket) 1 transitions into the support structure of the panels 21 etc. (e.g., of a vehicle) or is reduced to one part and the front side of the support membrane 24 is connected directly or indirectly to the underside or rear side of the panel or .is connected to the cover or cover layers 22 etc. in such a way that it can produce sound over it.

[0066] For a better understanding, FIG. 5 shows the 3D rear view of the integrated converter according to the invention.

[0067] Here you can see the support structure (converter cage) 1 with the air passages with bars 10, the radiating damper 3/23, the number of rays with holes of which should correspond to a prime number if possible, and the central guide damper 12 with its bars 12 and air passages 13, the number of which should be a prime number if possible should correspond.

[0068] For a better understanding, FIG. 6 shows the 3D front view of the integrated converter according to the invention with its membrane 2 and the section line indication A-A.

[0069] A version of a variant of the mounted integrated converter according to the invention in a cladding support structure (e.g., in the vehicle) 21 is shown in FIG In this case, the membrane 2 of the transducer according to the invention is not directly or indirectly attached with its front side to the underside or back of the lining or cover or cover layers 29 etc., the lining or cover or cover layers 29 should be perforated or sound-permeable and stable, so that protection against accidental contact, e.g., grid 30, is superfluous.

[0070] The highly integrated version according to FIG. 4 is shown in FIG. 8. In addition, a protection against accidental contact or grid 30 is shown or proposed here.

[0071] In summary, the invention therefore discloses an integrated converter in hybrid design with: [0072] a transducer basket with bars and air passages, the number of which should correspond to a prime number if possible, [0073] a first flexible multi-layer support membrane, which can have a different thickness profile and punctiform ring-shaped embossings between its center and outer edge and in the center of which there is a spiral conductor track on the underside back, at the respective ends of which the electrical contact +/− is located, [0074] a first magnet system (consisting of yoke, magnet, pole plate), [0075] a first ring-shaped copper cap on the pole core in the center of the first magnet, which together with the pole plate forms the air gap of the first magnet, [0076] a first voice coil, consist of a coil carrier with two electrically separated coils wound one behind the other, each of which is contacted via its own electrical contact +/− and the two coils dip into the air gap while the other side of the coil carrier connects the voice coil to the underside of the first membrane connects, [0077] a first central guide damper with webs and air passages, the number of which should correspond to a prime number if possible, [0078] a second central magnet located in the center of the first central guide damper, [0079] a third revolving magnet (with opposite polarity to the second central magnet) which is located on the central guide damper, [0080] a first elastic perforated radial damper whose number of rays with holes correspond to a prime number, via which the first multi-layer membrane flexibly connects to the transducer basket via an external narrow web, [0081] a first elastic central damper, which is located in the center on the second central magnet and thus elastically connects the underside of the first support membrane with the first central guide damper, [0082] a second elastic rotating damper, which is located on the third rotating magnet and thus elastically connects the underside of the first support membrane to the first central guide damper, [0083] a first supporting structure with a correspondingly thin, flexible covering in which the transducer basket is mounted or integrated with all the parts described above in such a way that the front or surface of the membrane can be connected to the back of the covering layer in such a way that sound is then generated via the covering can be.

[0084] The claims for protection now filed with the application and later are attempts to formulate without prejudicing the achievement of further protection. The references listed in the dependent claims indicate the further development of the subject matter of the main claim through the features of the respective sub-claim.

[0085] However, these are not to be understood as a waiver of achieving independent, objective protection for the features of the dependent claims. Features that were previously only disclosed in the description can be claimed in the course of the procedure as being of essential importance to the invention, for example to distinguish it from the prior art.
