PROBLEM TO BE SOLVED: To provide a speaker device which reduces an assembling line of the speaker device. SOLUTION: A vibration system such as a vibration cone 26, or a center cap 27 is vibrated by a voice coil 22 and a driving magnetic circuit 21. A magnetic circuit for luminescence 32 which makes a magnetic field for an induction coil 31 making an LED 28 generate luminescence electromotive force, is independently installed from the driving magnetic circuit 21. Furthermore, the LED 28, the induction coil 31, and the magnetic circuit for luminescence 32 are collectively installed in the center cap 27. COPYRIGHT: (C)2005,JPO&NCIPI
