Integrated transducer
View Patent ↗Disclosed is a sound transducer, which can be assembled, integrated or installed primarily in the consumer, pro audio, installation and automotive sectors on land, water and air with minimal space requirements, use of materials and weight. The transducer includes a ring sound wave shaper having a very flat, thin multi-layered, flexible membrane, which generates point-shaped or ring-shaped sound within the membrane diameter.
1. An integrated converter, comprising of:
a transducer basket with bars and air passages the number of which should correspond to a prime number and a bar and circumferential groove;
a first flexible multi-layer support membrane which can have different thicknesses and punctiform annular embossings between its center and outer edge and in the center of which there is a spiral conductor rack on the underside or rear, at the respective ends of which the electrical contact is located;
a first magnet system consisting of yoke, magnet, pole plate;
a first annular copper cap on the pole core center of the first magnet, which together with the pole plate forms the air gap of the first magnet;
a first voice coil, consist of a coil carrier with two electrically separate coils wound in series, each of which has its own electrical contacts and the two coils are in immerse the air gap while the other side of the coil former connects the voice coil to the underside of the first support diaphragm;
a first central guide damper with webs and air passages, the number of which should correspond to a prime number if possible;
a second central magnet which is located in the center of the first central guide damper;
a third revolving magnet (with opposite polarity to the second central magnet) which is located on the central guide damper;
a first elastic, perforated radial damper, the number of rays with holes corresponding to a prime number as far as possible, via which the first multi-layer support membrane is flexibly connected to the transducer basket via an external narrow web with a groove,
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 to the first central guide damper;
a second elastic encircling damper, which is located on the third encircling magnet and thus elastically connects the underside of the first support membrane to the first central guide damper;
a first support structure with a correspondingly thin, flexible cover layer in which the converter cage is mounted or integrated with all the previously described parts in such a way that the front side or surface of the support membrane can be connected to the back side of the cover in such a way that this can then be done sound can be generated via the cladding.
2. The integrated converter according to claim 1 , wherein the electrical contact of the two coils on coil carrier and the contact of the spiral conductor track can also be done together.
3. The integrated transducer according to claim 1 , wherein the supporting membrane is also made uniformly and in one layer.
4. The integrated transducer according to claim 1 , wherein a further integrated version the first transducer basket is replaced or integrated into the supporting structure with the correspondingly thin flexible covering, so that all parts previously described are mounted or integrated is that the front or surface of the support membrane can be connected to the back of the cover layer so that the sound can then be made via the cover, and optionally including a protective grill.
5. The integrated transducer according to claim 1 , wherein the transducer according to the invention does not have a supporting membrane but generates the sound itself via the membrane, it has proven to be advantageous in front of the transducer, at a distance from the membrane to use a cover layer that is perforated without loss of sound transmission and is designed to be stable against touch and indentation.
6. The integrated transducer according to claim 1 , wherein the transducer is positioned horizontally, vertically, or overhead.
7. The integrated transducer according to claim 1 , wherein the transducer is integrated as an individual sound transducer or in combination with other loudspeakers or basses in the housing or other objects.
8. The integrated transducer according to claim 7 , wherein the transducer is designed as a so-called single-ended transducer or has a third revolving magnet, a spiral conductor track, a flatter central damper, a second central magnet, a central damper and, a circumferential damper, connecting the underside of the membrane with the upper side of the elastic central guide damper.
9. The integrated transducer according to claim 1 , wherein the flexible membrane, support membrane, circumferential damper, central damper, central guide damper and damper are formed as single or multi-layered films, non-woven fabrics, fibers, fabrics, foams, and sandwiches of plastics, metals or natural materials or mixtures thereof, and which, depending on the part and purpose, have an adhesive on one or two sides.
10. The integrated converter according to claim 1 , wherein the transducer basket is formed of plastics, metals, natural materials or mixtures thereof.
11. The integrated transducer according to claim 1 , wherein depending on the intended use or conditions, not only the membrane can have a rotationally symmetrical but also a different shape.
12. The integrated converter according to claim 1 , wherein the number of webs, air passages, openings do not correspond to prime numbers.
13. The integrated transducer according to claim 2 , wherein the supporting membrane is also made uniformly and in one layer.
14. The integrated transducer according to claim 2 , wherein a further integrated version the first transducer basket is replaced or integrated into the supporting structure with the correspondingly thin flexible covering, so that all parts previously described are mounted or integrated is that the front or surface of the support membrane can be connected to the back of the cover layer so that the sound can then be made via the cover, and optionally including a protective grid.
15. The integrated transducer according to claim 2 , wherein the transducer according to the invention does not have a supporting membrane but generates the sound itself via the membrane, it has proven to be advantageous in front of the transducer, at a distance from the membrane to use a cover layer that is perforated without loss of sound transmission and is designed to be stable against touch and indentation.
16. The integrated transducer according to claim 2 , wherein the transducer is positioned horizontally, vertically or overhead.
17. The integrated transducer according to claim 2 , wherein the transducer is integrated as an individual sound transducer or in combination with other loudspeakers or basses in the housing or other objects.
18. The integrated transducer according to claim 17 , wherein the transducer is designed as a so-called single-ended transducer or has a third revolving magnet, a spiral conductor track, a flatter central damper, a second central magnet, a central damper and a circumferential damper, connecting the underside of the membrane with the upper side of the elastic central guide damper.
