ELECTROACOUSTIC TRANSDUCER AND ELECTRONIC DEVICE USING THE SAME

摘要

An electroacoustic transducer has a magnetic circuit, a frame combined with the magnetic circuit, a diaphragm combined with a periphery of the frame, a voice coil, a terminal, and a holder covering the frame. The voice coil is combined with the diaphragm and a part of the voice coil is arranged in a magnetic gap of the magnetic circuit. The terminal, made of a metal plate having spring property and electric conductivity, electrically connects an outside circuit and the voice coil utilizing spring pressure generated when the metal plate is bent. The holder forms a stopper for restricting a bend of the metal plate forming the terminal to within a reversible limit of a metallic material.
