響変換器の駆動部の取付け構造。 A cylindrical resin case houses a diaphragm and a drive unit that generates an alternating magnetic field that vibrates the diaphragm. In the electromagnetic acoustic generator, the electromagnetic sound generator is constructed by integrally or fixedly disposing facing poles made of magnetic material, winding the poles, and fixing a permanent magnet surrounding the winding portion to the yoke. The yoke is fixed to the inside of the case, the permanent magnet is magnetically attracted to the yoke, a stopper is provided inside the case to prevent the permanent magnet from detaching from the yoke, and the stopper and the permanent magnet are connected to each other. A mounting structure for a driving part of an electromagnetic acoustic transducer, characterized in that a gap is provided between the parts.
