Definitions

  • the invention relates to a loudspeaker with a voice coil connected to a membrane, in which elastic band conductors serve as feed lines to the winding ends of the voice coil and each band conductor is fastened on the one hand to the voice coil and on the other hand to a fixed part of the loudspeaker.
  • the object underlying the invention is to further develop the known loudspeaker in such a way that it is accessible for automatic production.
  • the voice coil is arranged on a part of the longitudinal extent of a cylindrical voice coil support, on the remaining part of the voice coil support parallel to the longitudinal axis of at least two flexible tape lines attached to a plastic support and their ends by means of a thermosetting adhesive film on the Voice coil holder attached and the ends of the voice coil with these ends of the ribbon cables are electrically connected.
  • the voice coil carrier 2 can be, for example, an aluminum foil formed into a tube.
  • a flexible plastic carrier 3 made of an electrically highly conductive metal layer, for example copper, are fastened.
  • KLebefoLie 6 is, for example, a commercially available thermoplastic reaction adhesive in film form with a thickness of 0.06 to 0.08 ⁇ m based on nitrile rubber / phenolic resin.
  • the parts to be connected with such a film are usually processed with a heatable and coolable press at temperatures between 100 and 200 ° C and contact pressures of 0.2 to 1 N / mm 2 .
  • the tape lines 4 are provided with the flat tin bead 7 in order to facilitate the connection of the voice coil end.
  • the other ends of the ribbon lines 4 can - as can be seen from FIG. 1 - be provided with such tin beads 7.
  • Fig. 3 shows an embodiment of the plastic carrier tape line arrangement in cross section.
  • This consists of the plastic carrier 3, which is, for example, a polyimide film with a thickness of 25 ⁇ m.
  • the ribbon lines 4 are arranged, which consist for example of copper and have a thickness of 35 ⁇ m.
  • the top coat layer 8 is applied to the plastic carrier 3 and the ribbon cable 4. This layer serves on the one hand to isolate the ribbon cables and gives the plastic carrier ribbon cable arrangement a certain stiffness, which has a vibration-damping effect.
  • the embodiment of the plastic carrier tape line arrangement shown in FIG. 4 differs from that shown in FIG. 3 in that a polyimide cover film 9 is provided instead of the cover lacquer layer 8.
  • FIG. 5 shows the view of a loudspeaker basket 10 which, for example, is injection-molded in one piece from plastic and in which the cone membrane has its place in the finished loudspeaker.
  • 10 contact pieces 11 are arranged in the loudspeaker basket, which are designed in such a way that they internally, i.e. have contact surfaces 11 on the side facing the membrane and the voice coil and are designed on the outside as tabs 12 onto which flat plugs can be attached, for example.
  • the free ends of the ribbon cables can then be soldered to the contact surfaces 11 by means of the tin beads 7 (cf. FIG. 1).
