Abstract

PURPOSE:To obtain a voice coil having high responsiveness with high power by constructing the voice coil of a plurality of conductors connected in parallel with each other. CONSTITUTION:A voice coil 8 is formed of a plurality of coils 8a, 8b connected in parallel with each other. When the number of turns of the coils 8a, 8b is assumed to be N/2 to compare this with a single coil of number N of turns, the time constant of the coil can be improved to 1/4. Accordingly, by providing the voice coil formed of a plurality of parallel coils, the abrupt increase of the inductance proportional to the increase in the number of turns of the entire coil can be avoided, thereby obtaining a voice coil device of high responsiveness with high power.
