Abstract
A voice coil and a magnetic driving circuit oscillate a diaphragm and a center cap. A magnetic lighting circuit for providing a magnetic field to an induction coil is mounted separately from a magnetic driving circuit. The induction coil generates an electromotive force for lighting light-emitting devices. Further, the light-emitting devices, the induction coil, and the magnetic lighting circuit are mounted integrally on the center cap.
