Definitions

  • the end portions of the coil lead wires 11 and 12 extending out of the reinforced paper 1B are subjected to terminal processing, namely the insulating layers of the end portions of the coil lead wires 11 and 12 are removed to expose the inner conductive wires which are coated by solder.
  • the wire 16 is formed by wiredrawing to a diameter of 0.19 mm, and is coated with an insulating film over the surface thereof.
  • This voice coil 1 has no bobbin so as to reduce the weight.
  • about two turns of the coil is wound on the third winding layer near at the winding end points 14. This particular structure for preventing peel-off is omitted in other Figures to simplify the drawings.
  • two wires are serially connected via the copper foil 1C3.
  • the two wires may be connected in parallel depending on the coil specification without using the center copper foil as shown in Fig.7.
  • the copper foils 1C are attached to the surface of the craft paper, if for example the insulating strength is not required so much, they may be directly attached to the outer circumferential surface of the coil 1 as shown in Fig.8 because the coil 1 itself has a coated insulating film, or they may be coated with an insulating film such as phenol film on the side to be attached to the coil 1.
  • a material having a higher insulating strength such as an insulating film may also be used.
