イスコイル型モータ。 A moving coil that rotates in the gap between the two yokes is attached to the inner surface of the opposing yokes.A permanent magnet is fixed in the axial direction so that the magnetic properties of adjacent magnetic poles and opposing magnetic poles are different, and between the opposing yokes. fixes two opposing yokes with a support made of soft magnetic material with an air gap inside the permanent magnet, forms a magnetic circuit with the yoke, permanent magnet, and support, and moves parallel to the permanent magnet within the air gap. 1. A swing-type voice coil motor having moving coils arranged therein, the voice coil motor being characterized in that a yoke and a support are constructed as an integral piece made of a rectangular cylindrical soft magnetic material.
