Claims

[Scope of utility model registration request]

In a speaker in which the inner edge of the diaphragm is supported by a damper via a voice coil hobbin fixed to the diaphragm, the dampers are double-layered, each having an annular inner periphery fixed to the voice coil hobbin and a frame. Or an annular outer periphery fixed to the plate of the magnetic circuit, and a plurality of corrugated supports extending tangentially from the inner periphery and gradually increasing in width and curving outward to reach the outer periphery. , and the tangential directions of the supporting parts are opposite to each other.
