Abstract

PURPOSE:To obtain a dumper for speaker having a high damping effect and free from the vibration fault of the vibrating part, by using a composite material of the resin, the graphite and the softening material which have a light weight, high Young's modulus and high internal loss each. CONSTITUTION:The thermoplastic resin 1(polyvinyl chloride only or the copolymer of vinyl acetate, etc.), the flasky graphite powder 2 (average grain size of 5m) and the hardening material (plasticizer such as BPBG, DOP, etc. or synthetic rubber such as NR, NBR, etc.) are used mainly to be kneaded, rolled and formed each. Thus a dumper for speaker with the powder 2 provided along the surface can be obtained.
