Abstract

PURPOSE:To improve the distortion characteristics at a low band, by providing a sliding element at the position which is opposite to both surfaces of a plate or both surfaces of the plate of a pole piece and then supplying an aural current to a voice coil through the sliding element. CONSTITUTION:A sliding element 12 is provided at the position opposite to the inner circumference surface of a plate 2 and at a part of a pole piece 1. An aural current is supplied to the element 12 via a lead wire 13, and thus the aural current is supplied to a voice coil 4d through the element 12. The aural current is always supplied to the coil 4d only at a part (c) which is held between the upper and lower elements 12 regardless of the position of the coil 4d. In this connection, the coil 4d never swells out over the concentrated part of magnetic flux by setting the winding width of coil 4d slightly larger than the required maximum amplitude. Thus the occurrence of distortion can be reduced.
