る電磁音響変換器。 A base equipped with a pole with a wire wound thereon and a yoke integral with the pole and with a fixed terminal pin is housed in a resin case, with one end of the terminal pin protruding from the outer surface of the base, and a base mounted inside the outer surface of the base. Fix the end of the winding to the other end of the terminal pin located at
In the electromagnetic acoustic transducer, the gap between the resin case and the base is filled with a thermosetting resin to prevent sound from leaking from the side opposite to the sound outlet. An electromagnetic acoustic transducer characterized in that resin sheets that fit on the inner surface are stacked, and the thermosetting resin for fixing the base is applied to the outer surface of the resin sheets.
