Member for speaker

摘要

PROBLEM TO BE SOLVED: To simultaneously obtain excellent heat resistance, flexibility, moisture resistance, inside loss and aspect rate by forming this member for a speaker of elastomer composition containing specific thermoplastic elastomer as main agent. ;SOLUTION: A member for a speaker is formed of elastomer composition. The elastomer composition contains thermoplastic elastomer (aramid system thermoplastic elastomer) having a hard segment constituted of whole aromatic group amide parts and a soft segment constituted of polyoxyalkylene ether parts as main agent. For example, poly-p-phenylene phthalamide or poly-p- phenylene isophthalamide or the like is used as amide forming the whole aromatic group amide parts. The polyoxyalkylene parts are representatively derived from the polyoxyalkylene ether, and polytetramethylene ether glycol or polypentamethylene ether glycol or the like is used as the ether.;COPYRIGHT: (C)2000,JPO
