気音響変換器の保持構造。[Claims for Utility Model Registration] The electroacoustic transducer unit consists of an electroacoustic transducer unit, a terminal board, a housing, and an elastic ring, and the electroacoustic transducer unit has a diaphragm on the front, a frame on the side, a drive part, A terminal board is formed by a circular outer bottom surface of the driving portion on the rear surface, and a terminal board is fixed to the circular outer bottom surface of the driving portion and has a circumferential portion whose outer peripheral portion is slightly larger than a diameter of the outer bottom surface of the circular driving portion; The housing is a housing body made of synthetic resin, with a circumferential notch formed on the top surface or the outer periphery, and a lead wire at the bottom. A drawer through hole is formed, and ribs are integrally formed at appropriate intervals in the circumferential direction in the middle of the inner circumferential surface, and ribs are formed with protrusions for preventing removal at the tips, and the electroacoustic transducer unit is placed inside and rotated at an appropriate angle. The circumference of the terminal board elastically deforms and locks the rib outward, and an elastic ring is formed on the inner peripheral surface between the notch of the housing and the frame and has a concave cross section. A protrusion having a semicircular cross section with a width larger than the opening width of the circumferential groove is integrally formed and elastically expanded to press the protrusion having a semicircular cross section into the open groove part of the circumferential groove, and the frame and A holding structure for an electroacoustic transducer elastically attached to the housing.
