Abstract

PURPOSE:To realize a thin-gage speaker by using the magnetic circit with the magnetization of S, N, S and N poles each to the ring-type magnet with the 90 degree space secured plus the same pole connected to the center pole each. CONSTITUTION:The S and N poles are magnetized alternately to ring-type magnet 16 with the 90 degree space secured between, and the S pole is connected to center pole 22 via connection bar 25. While the N pole is connected to each other via connection bar 20 so as to form magnetic gap 28 around pole 22. In such constitution, bars 20 and 25 are set to the smaller thickness than magnet 16 around pole 22 via taper parts 21 and 26. The magnetic circuit of such constitution has only the thickness of magnet 16. At the same time, diaphragm 31 possessing voice coil 32 and folded part 30 are attached to frame 29 at the fringe of the magnet in the normal way.
