Abstract

PURPOSE:To make excellent the degree of separation of left and right channels, by providing the magnetic circuit which gives orthogonal magnetic flux to the axial center of the cuntilever, at the external part of the armature at one side of the oscillation system. CONSTITUTION:At the end of the cuntilever 2 having the stylus 1 at the tip, the coreless coil (not shown) as the armature is fixed, and the oscillation system is constituted by supporting the axial center of the lever 2 of the armature at the fulcrum in oscillation free. Further, at the external side of armature orthogonal to the axial center of the lever 2, the central yoke 11L1 of the E-shaped yoke 11L is located at a gap, and the front magnet 12L and the rear magnet 13L are respectively fixed to the both sides of the yoke 11L. Further, the magnetic circuit is constituted that the coil 4L as the armature is clipped from the direction in parallel with the axial direction of the lever 2, and the magnetic circuit gives magentic flux from the orthogonal direction to the axial center of the lever 2 from the outside of the coil 4L.
