Claims

[Claims for Utility Model Registration] (1) An acoustic converter, a base on which the acoustic converter is arranged on one surface in the thickness direction, and a pin embedded in the base so as to penetrate in the thickness direction of the base. The terminal has a side located on the one surface side of the base that is bent in the outer circumferential direction of the base to protrude from the outer circumferential edge of the base, and the acoustic converter is attached to the end of the terminal. An acoustic transducer characterized in that the power supply lead wires of the parts are connected by intertwining them. (2) The acoustic conversion unit includes a yoke disposed on one surface of the base, a pole mounted upright on the yoke, a coil attached to the pole, and a coil surrounding the pole and the coil. Claim 1: A utility model registration device comprising: a magnet disposed on the yoke; and a diaphragm disposed so as to face the tip end surface of the pole with a gap in between. The acoustic transducer described in . (3) The acoustic transducer according to claim 2, wherein the terminal is bent toward the outer periphery of the base at a position that does not protrude from the pole mounting surface of the yoke. (4) The acoustic transducer according to claim 2 or 3, wherein the base, the yoke, and the pole are integrally combined. (5) The acoustic transducer according to claim 2, 3, or 4, wherein the coil is directly attached to the pole. (6) Utility model registration claims 1, 2, and 3, characterized by having a case in which the base is arranged at the bottom and the acoustic converter is housed inside.
4. The acoustic transducer according to item 4 or 5.
