Definitions

  • the invention relates to an exciter for a surface-area loudspeaker with the features of the preamble of claim 1.
  • Such an exciter is already out of the DE 102 06 129 A1 known.
  • the oscillating in an annular air gap of a permanent magnet coil is coupled via a molded part - the vibrating part carrier - to a sound-emitting surface.
  • the DE 10 2004 001 215 and the EP 1 207 716 A2 show such, particularly advantageous designed vibrating part carrier for exciters.
  • the object of the invention is therefore to provide an exciter with a simple structure that allows fast and accurate installation.
  • the exciter according to the invention on a vibrating part carrier with an inner and an outer ring, which are interconnected with spring elements.
  • the inner ring of the vibrating part carrier is immobilized and the outer ring connected to the coil carrier of the vibrating part carrier coupled by means of a releasably connected to the oscillating part carrier coupling ring for generating sound to a surface membrane.
  • hook elements are provided on the vibrating part carrier and the coupling ring, which engage in a rotational movement into one another. This construction allows a fast and precise mounting of the surface diaphragm loudspeaker.
  • the exciter consists of an annular gap magnet system 40, which is composed of a magnet pot, a neodymium ring and an upper pole plate.
  • annular gap magnet system 40 In the annular gap of the annular gap magnet system 40, a coil carrier carrying a voice coil 30 is used, which is preferably glued to a vibrating part carrier 20.
  • the 2 comprises an outer ring 60 and an inner ring 80 connected to the outer ring 60 via spring elements 70.
  • the inner ring 80 has a receptacle 90 for a fastening means for vibration-free fixing of the inner ring 80, FIG. For example, a threaded hole for receiving a screw.
  • the inner ring 80 is fixed, wherein the coupled via the spring elements 70 to the inner ring 80 outer ring 60 of the movement of the immersed in the annular gap of the permanent magnet 40 bobbin 30 can follow.
  • the inner ring preferably has receptacles 100 for connecting an electrical connection 50, for example in the form of a flat tongue 50, on which supplies the coil on the bobbin 30 with power.
  • the spring elements 70 preferably do not extend over the circumference of the annular gap of the magnet system 40. This ensures that the generation of sound in principle and also under motion, for example, by movement of the entire speaker in a moving vehicle, a lower susceptibility subject ,
  • the vibrating part carrier 20 is provided with a coupling ring 10, wherein this coupling ring 10 is connected to the surface membrane, for example glued.
  • the latching element receptacles 110 may be, for example, trough-shaped depressions or bores which partially or completely penetrate the vibrating part carrier.
  • the vibrating part carrier 20 preferably has a plurality of circularly arranged hook elements 120.
  • the latching element receptacles 110 and the hook elements 120 of the vibrating part carrier find their counterpart on the coupling ring 10 shown larger in FIG. 3 in the latching element carrier facing latching elements 130 and hook elements 140.
  • the hook elements 120 of the vibrating part carrier 20 and the hook elements 140 of the coupling ring 10 are arranged to each other in that the hook elements 120, 140 engage in a rotational movement. In this case, prevent the engaging in the Rastaufhahmen 110 of the vibrating beam 20, preferably elastically deformable locking elements 130 of the coupling ring loosening the rotational movement caused form-fitting connection between vibration member carrier 20 and coupling ring 10.
  • the hook elements 120 of the vibrating member carrier 20 and the hook members 140 of the coupling ring 10 th an equal number, while the locking elements 130 are preferably applied in a smaller number than the locking element receptacles 110.
  • the advantage of a coupling ring is that on the one hand preassembled the exciter, on the other hand, the surface membrane can be connected to the coupling ring 10 and both elements must be assembled by rotational movement only. As a result, a precise assembly is much easier.
  • FIGS. 4, 5 and 6 show a further embodiment of an exciter according to the invention.
  • This second embodiment differs from the exemplary embodiment illustrated in FIGS. 1, 2 and 3 in that the hook elements 120 of the vibrating part carrier 20 are arranged on the outer circumference of the vibrating part carrier 20 to extend outward from the vibrating part carrier 20.
  • the complementarily arranged hook elements 140 of the coupling ring 10 are accordingly directed inwardly to the center of the coupling ring 10.
  • This second exemplary embodiment according to FIGS. 4, 5 and 6 has the advantage over the embodiment shown in FIGS. 1, 2 and 3 that the coupling ring 10 does not have to be inserted carefully and precisely into the vibrating part carrier 20, but rather that the coupling ring 10 mounted for attachment to the vibrating part carrier 20 with a simple movement of the vibrating part carrier 20 and the vibrating part carrier 20 can be rotated comprehensively. As a result, a simpler handling compared to the first embodiment is made possible.
