Abstract

PURPOSE:To reduce self-inductance of a moving coil and to improve frequency response by interposing permanent magnets between sections formed by cutting the opposed extension sections of a yoke body. CONSTITUTION:A yoke body 10 is constituted of two of U-yoke 11 and a center yoke 13. Each both side piece 12 of each yoke 11 constituting one opposed extension section of the yoke body 10 and placing on a common straight line has a permanent magnet 14 which is secured to the inside surface across the both side piece, and field magnetic flux is formed between the opposed extension sections. For the magnetic magnet 14, a permanent magnet projection 15 having the same direction of magnetization as that of the permanent magnet 14 is secured to the center part in the direction of extension of a binding surface with opposed extension section 12. A moving coil 16 is placed so as to be movable along by the center yoke 13. The yoke 11 is divided into two, and since the permanent magnet 15 is interposed between the both side piece 12 two, the self-inductance of the moving coil 16 is reduced.
