Abstract

PURPOSE:To improve the non-linearity of a driving force and to make the manufacture easy, by bundling a plurality of leads corresponding to the number of bits of a PCM signal as one set through insulation among leads and continuously winding at once as a voice coil. CONSTITUTION:A plurality of conductors 12 corresponding to the number of bits of a PCM signal are bundled in a round wire as one set by providing insulation to each conductor and they are wound on a coil bobbin 1 at once. A magnetic flux B between a plate 3 and a pole 4 is applied uniformly to each voice coil by winding the leads 12 like this and the linearity can also be improved, allowing to obtain a driving force proportional to a pulse signal current applied to each voice coil.
