摘要：
A volume ratio of conductive material to a voice coil is improved by using a tape coil wire, and a magnetic efficiency of the voice coil is improved by attaching magnetic material to conductive material of the coil wire. A tape coil wire having a predetermined width is wound about a voice coil bobbin to form a voice coil. The winding start portion of the voice coil is soldered to the exposed area of the voice coil bobbin. A projection of the voice coil bobbin forms the winding start terminal. A folded portion of the winding end portion of the voice coil forms the winding end terminal. Input signal lead wires on the damper are electrically connected to the winding start and end terminals to drive the cone paper by the voice coil.
