PURPOSE:To make easy the replacement of an oscillation system, by fixing the oscillation system with a frame. CONSTITUTION:A cone 1, edge 2, voice coil 5, damper 7 and bobbin 9 constituting the oscillation system are unifiedly assembled with a center cap 10. Further, the external circumference of the damper 7 is bonded on the upper surface of a supporting 11, and the ring 11 and an arm 12 are incorporatedly assembled with the oscillation system. In case of assembling of a speaker, a projection 11a of the ring 11 is inserted to a recess 3a of a plate 3 and tightened with a screw 13, If there is any hindrance in the oscillation system, since the oscillation system can be removed by untightening the screw 13, only the oscillation system can be simply replaced. |
