Definitions

  • the invention relates to a method for producing an electrodynamic transducer, consisting of a body for receiving a permanent magnet system and the membrane with a voice coil, which can be inserted into a housing that can be closed with a lid, the housing and / or the body on the underside thereof Electrical amplifier circuit with electrical pins and the body is provided with two parallel slots for receiving the lead wires of the voice coil, the spacing of which corresponds to the diameter thereof, the two lead wires of the voice coil in parallel at a distance corresponding to the diameter thereof on a support at one point are attached at a certain distance outside the membrane and when installing the membrane in the body, the two connecting wires below the membrane are led to the outside of the body.
  • EP-A1 22544 describes an electrodynamic transducer which has a body which is provided with two parallel slots at a distance from the outer diameter of the voice coil attached to the membrane for receiving the lead wires of the voice coil in order to connect them to the underside of the body to lead existing amplifier circuit.
  • the continuous production of membranes from an endless band by step-wise shaping is described in FR-OS 21 51 047.
  • the material from which the membrane is formed consists of an electrically non-conductive material.
  • the tape is provided in its longitudinal direction with two parallel conductor tracks, which are spaced apart from the outside diameter the voice coil is attached to the tape material on the top or bottom.
  • the object is achieved in that the lead wires are guided with the aid of the carrier, that the carrier is formed by the amplifier circuit, which is guided and punched out in parallel with a strip from which the membrane is formed, that the lead wires with the Connection pins are connected so that the connecting wires are inserted into the slots of the body, then the membrane is inserted and then the amplifier circuit is attached to the underside of the body.
  • the carrier is formed by the amplifier circuit, which is guided and punched out in parallel with a strip from which the membrane is formed
  • the lead wires with the Connection pins are connected so that the connecting wires are inserted into the slots of the body, then the membrane is inserted and then the amplifier circuit is attached to the underside of the body.
  • An advantageous development of the invention also consists in the fact that the carrier is formed by the tape from which the membrane is formed, that the membrane and the carrier are partially punched out, and that after the voice coil has been fastened to the membrane, the connecting wires are fastened to the carrier the membrane and the carrier are punched out. If the band material from which the membrane is drawn is chosen to be sufficiently wide, the carrier can be produced from the same band. The specified wire length between the voice coil and the carrier is clearly defined. Further advantages result from the exemplary embodiments.
  • Fig. Shows the individual operations for producing a membrane.
  • the transport holes 9 are first punched into the band-shaped material 7, these serve both for the movement of the band 7 and for exact positioning.
  • Process step A relates to the shaping of the membrane 5 by, for example, deep drawing.
  • method step B the surfaces 10 are punched out, using the membrane and the carrier continues to be held in the band by the left webs 11.
  • the voice coil 2 is inserted and glued into the diaphragm 5 in method step C, the two connecting wires 1 of the voice coil 2 are also fastened to the points 3 on the carrier 3. This is done at a distance from the outer diameter of the voice coil.
  • the last process step involves punching membrane 5 and carrier 3 free by removing the webs 11. The membrane can now be inserted into the body.
  • Fig. Shows the use of the amplifier circuit 24 as a carrier, on the pins 23, the two connecting wires 1 of the voice coil are attached during step C.
  • the amplifier circuit 24 can now be moved and punched out in parallel on a special carrier tape with the tape material. It only has to be ensured that the amplifier circuit 24 is moved in parallel with the connected voice coil until punching free (method step D).
  • FIG. 5 shows the cross section of a complete electrodynamic converter, an amplifier circuit 24 being attached to the underside of the body 20.
  • the two connecting wires 1 are inserted into the slots 21 with the aid of the carrier and guided to the amplifier circuit 24 on the underside of the body 20 to the connecting pins, where one wire is wound around a connecting pin. With the help of the carrier, this can be done simultaneously with both connecting pins.
  • the protruding wire ends are then cut off on the carrier. If the voice coil 2 of the membrane 5 is already connected to the amplifier circuit 24 as shown in FIG. 3, the membrane 5 is inserted into the body, the two connecting wires are guided through the amplifier circuit 24, inserted into the two slots 21 and then the Amplifier circuit 24 attached to the underside of the body 20.
