PURPOSE:To secure an ample gap between the cone and the magnetic circuit for the reverse-type speaker unit by providing the damper to hold the voice coil elastically in the front of the cone or on the back of the magnetic circuit. CONSTITUTION:Holding component 11, which contains radial arm 11a and ring 11b at the inner edge with the outer end attached to frame 6, is provided in the front of cone 5. Then the outer circumference of damper 7 is attached to ring 11b of component 11, and at the same time the tip part of voice coil 4 is attached to the inner circumference of damper 7. Thus, coil 4 can be held elastically. With such constitution, the attachment surface of frame 6 to the baffle plate of the front face of the cabinet can be distributed nearly on the same level as the sound source, i.e., the position of coil 4. As a result, the positions of the sound sources can be set even for each speaker in the case of the multi-speaker system. |
