Definitions

  • the invention relates to a vibration unit according to the preamble of claim 1.
  • the voice unit of a dynamic loudspeaker is formed from a voice coil support, a membrane, a centering part and a flexible connecting line serving for the power supply of the voice coil.
  • a vibrating unit with a centering part made of fabric in which the connecting lines for the voice coil are formed by conductive fabric threads, in particular from stranded wires.
  • the invention has for its object to make the vibrating unit of a speaker reliable with little effort.
  • the centering part which can be produced with little effort, allows a current supply which is not impaired by the bending stresses which occur during the operation of the loudspeaker, since the contacting of the voice coil connection ends with the connecting tabs of the conductor tracks outside the mechanically stressed connection zone located.
  • the cl. Connection of the conductor tracks constructed in the manner of a printed circuit to the voice coil connection ends is completely problem-free and reliable.
  • a conical membrane 1, which is only partially shown in FIG. 1, is firmly connected in a manner known per se to an annular, centrally arranged beads 2 having a centering part 3 and a voice coil support 5 provided with a voice coil 4.
  • the centering part 3 is made of a flexible printed circuit board material, for example copper-clad polyester, provided with conductor tracks 6, 7 in the manner of a printed circuit.
  • the oppositely arranged conductor tracks 6, 7 serving as connecting lines for the voice coil 4 each extend according to FIG.
  • the inner connection tabs 9, 10 are attached to the voice coil former 5, parallel to its longitudinal axis, running to the voice coil 4. However, they can also end on the membrane 1 and be attached to it.
  • the voice coil terminal ends 13, 14 are at the ends of the inner ones Connection tabs 9, 10 electrically connected in the usual way.
  • the electrical connection points P are thus outside the connection zone membrane / centering part / coil support and are therefore exposed to negligible bending stress.
  • the outer connection tabs 11, 12 are provided for an electrical connection, not shown, to the terminals of the loudspeaker.
  • the conductor tracks 6, 7 can be covered with an insulating film 15.
