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.

Un convertisseur électro-acoustique comprend un circuit magnétique, un cadre raccordé au circuit magnétique, une membrane raccordée à la périphérie du cadre, une bobine vocale, un bornier et un support couvrant le cadre. La bobine vocale est raccordée à la membrane et elle est disposée pour partie dans l'espace magnétique du circuit magnétique. Le bornier est constitué d'une plaque métallique conductrice faisant ressort. Le bornier est raccordé électriquement au circuit externe par la bobine vocale grâce à la pression du ressort lorsque la plaque métallique est cintrée. Le support agit comme une butée régulant le cintrage de la plaque métallique constituant le bornier en deçà d'une valeur limite réversible du matériau métallique.
