摘要 A damper, which is an element of a speaker and suppresses the rolling of a voice coil unit, includes a corrugated structure portion at its inner periphery and a leaf spring at its outer periphery. By coupling the corrugated structure portion to the voice coil unit and coupling the leaf spring to the frame, the distortion of a speaker can be reduced and the driving efficiency can be improved.
