MEMBER FOR ELECTROACOUSTIC TRANSDUCER

摘要

PROBLEM TO BE SOLVED: To provide a member for an electroacoustic transducer applicable to an electroacoustic transducer such as a speaker used for electronic devices and acoustic devices that has excellent heat resistance, adhesion strength and corrosion resistance. SOLUTION: A basic metallic layer if (formation film) is formed on the surface of the member for the electroacoustic transducer through the forming processing using a solution containing a basic metal in place of chromate processing on the member for the electroacoustic transducer subjected to zinc plating 1e and a resin layer 1g made of a silicon group or the like is placed on the surface as a water soluble or water dispersion resin layer.
