摘要： An electric acoustic converter wherein a stopper of a terminal is composed of an elastic body having an impulsive-force resistance and an excellent resilience and wherein this stopper is coupled to an electromagnetic circuit, such as a yoke or a lower plate, that is made of a metallic material having an impulsive-force resistance. In this way, the stopper can restrict the terminal within the reversibility limit value of the spring force of a metallic end portion, and hence can enhance the reliability.

摘要： An electro-acoustic converter includes an magnetic circuit, a frame connected to the magnetic circuit, a diaphragm connected to the periphery of the frame, a voice coil, a terminal, and a holder covering the frame. The voice coil is connected to the diaphragm and a part of it is arranged in the magnetic gap of the magnetic circuit. The terminal is made of a metal plate having spring characteristic and conductivity. The terminal electrically connects the external circuit with the voice coil by utilizing the spring pressure when the metal plate is bent. The holder constitutes a stopper regulating the bending of the metal plate constituting the terminal within a reversible limit value of the metal material.
