Abstract

PURPOSE:To hold correctly a voice coil on the center of a magnetic gap by bonding concentrically a diaphragm to a frame to eliminate the need for a damper holding the voice coil on the center of the magnetic gap. CONSTITUTION:The speaker is provided with a field part where a plate 2 and a magnet 3 are fixed to the center of a cap type yoke 1 and a circular magnetic gap 4 is formed. Further, a cap type recessed part 5a on the center of which the yoke is pressed and a frame 5 forming a horizontal ridge 5c respectively surrounded with a cylindrical standing ridge 5b concentric to the recessed part 5a is provided to the outer peripheral part. Further, the horizontal ridge 6c bonded to the upper face of the horizontal ridge 5c of the frame 5 and a step 6c fitted to the cylindrical inner diameter face 5d of the cylindrical standing ridge 5b of the frame 5 at the outer peripheral part are formed. Then a diaphragm 6 on the center of which the voice coil 7 inserted to the magnetic gap 4 is bonded is provided and the coil 7 is held at the center of the magnetic gap 4.
