Claims (1)

[Claim for Utility Model Registration] A damper material made of woven fabric or non-woven fabric is impregnated with phenol resin, etc., and concentric corrugated corrugations are integrally formed by thermoforming, etc., and the inner periphery is formed along the shape of the corrugation. In a damper for a speaker in which a conductive part for audio signal input is provided by pasting two pieces of conductive material from the part to the outer periphery, the conductive material is a flat tinsel wire made of tinsel wire braided into a flat mesh shape. A speaker damper structure characterized by:
