VIBRATING MEMBRANE FOR ELECTROACOUSTIC TRANSDUCER AND ELECTROACOUSTIC TRANSDUCER

摘要

PROBLEM TO BE SOLVED: To provide a plane type electroacoustic transducer of a moving magnet type formed by a vibrating membrane having a thin film magnet magnet-landed to a thickness direction. SOLUTION: The thin film magnet 12 is film-formed on a macromolecule film 11 such as a polyimide resin and the like by cobalt chromium and the like, and the vibrating membrane 10 formed by magnet-landing the thin film magnet 12 to the thickness direction is arranged in an air-core coil 20.
