Claims (1)

[Scope of Claim for Utility Model Registration] A damper material made of woven or non-woven fabric is impregnated with phenol resin, etc., and a corrugated corrugation is integrally formed by thermoforming, etc., and the corrugation is formed along the shape of the corrugation from the inner circumference to the outer circumference. In a speaker damper in which a conductive part for audio signal input is provided by pasting two sheets of conductive material in the direction of the damper, the conductive part is provided in two directions at symmetrical positions, and there is a conductive part on the outer periphery of the damper. A speaker damper structure characterized in that an input terminal is provided that is directly coupled to each conductive part.
