PURPOSE: A high output flat plate type of a speaker having a magnetic circuit of a laminating structure is provided to comprise the magnetic circuit of a vertical laminating structure, thereby performing a high output slim speaker and a high output slim woofer. CONSTITUTION: Magnetic bodies(11A,11B,12A,12B,13A,13B) perpendicularly laminate a pair of magnets which is faced to a different pole. A voice coil plate(14) is perpendicularly located between the magnets. The voice coil plate forms voice coils(141,142,143). A vibration plate(15) is touched to the voice coil plate. The vibration plate generates a sound by absorbing vibration of the voice coil plate. |
