DIAPHRAGM EDGE MATERIAL FOR MICROSPEAKER, MICROSPEAKER USING THE DIAPHRAGM EDGE MATERIAL FOR MICROSPEAKER, AND ELECTRONIC EQUIPMENT USING THE MICROSPEAKER

摘要

This invention provides a diaphragm edge material for a microspeaker which has been improved, for example, in heat resistance, cold resistance, moistureproofness, moldability, and high internal loss. A diaphragm edge material for a microspeaker is produced by heat molding an elastomer sheet formed of a simple material of a polyamide elastomer, or formed of a mixture prepared by internally mixing a functional elastomer such as a urethane elastomer into the polyamide elastomer, or formed of a laminate formed by adding the functional elastomer onto one side or both sides of the polyamide elastomer or between two sheets of the polyamide elastomers.
