磁音響変換器の駆動部の取付け構造。[Claims for Utility Model Registration] 1. A diaphragm and a drive unit that generates an alternating magnetic field that vibrates the diaphragm are housed in a cylindrical resin case, and the drive unit has a plate shape. A pole made of a magnetic material facing the diaphragm is integrally or fixedly provided on one side of the yoke, a winding is applied to the pole, and a magnetic material surrounding the winding is fixed to the yoke. In the electromagnetic acoustic generator, three or more elastic pieces are provided inside the case, integrally with the case, a groove is provided on the inner surface of each elastic piece, and the periphery of the yoke is pushed into each groove, and the drive unit A mounting structure for a driving part of an electromagnetic acoustic transducer, characterized in that: is fixed in the case. 2. In claim 1, a yoke locking portion is provided in the elastic piece instead of the groove, a yoke receiving portion is provided between each elastic piece of the case, and a connection between the yoke receiving portion and the yoke locking portion is provided. A mounting structure for a driving part of an electromagnetic acoustic transducer, characterized in that the yoke is fixed to a case by sandwiching the periphery of the yoke between the parts.
