1. A speaker apparatus comprising:
- an oscillation unit for generating a sound;
a drive unit having a voice coil and a magnetic driving circuit for providing a magnetic field to the voice coil to oscillate the oscillation unit;
light-emitting devices mounted on specific positions; and
an electromotive force generator for lighting the light-emitting devices including an induction coil and a magnetic lighting circuit, said magnetic lighting circuit being mounted separately from the magnetic driving circuit for providing a magnetic field to the induction coil, whereby owing to an oscillation of the oscillation unit, the induction coil of the electromotive force generator generates an electromotive force for lighting the light-emitting devices.

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.
