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 sheets of conductive material from the part to the outer periphery, the conductive part has a tape-like shape wider than the conductive part. 1. A damper structure for a speaker, characterized in that the conductive part is sandwiched between the damper body and the covering member.
