Abstract

PURPOSE:To keep the damper to a prescribed height by holding the outer circumference of a damper of a transducer to a case main body and its inner circumference to a yoke and constituting the case main body of a frame having a coil and a frame containing the yoke to couple both frames. CONSTITUTION:An air gap 12 is formed by the yoke 8 having a magnetic pole 10, the yoke 8 is held in the case main body 1 by the damper 6 and the coil 16 is held in the air gap 12 to constitute the transducer. The outer circumference 6a of the damper 6 is sandwiched by interposing the flanges 4, 5 of the frames 2, 3 of the main body 1 and the inner circumference 6b of the damper 6 is held by the yoke 8. A port 14 is formed at the center of the frame 3, the port 14 is fit with the cylindrical coil frame 15 set to the plate 15a, and the plate 15a is fixed incorporatedly with the frame 3. The frames 2, 3 are coupled to facilitate the fitting of the damper 6 to the main body 1 and to hold the position at a prescribed height.
