PURPOSE:To simplify the constitution of a magnetic means not to require precision for the gap, by providing three leg parts in the armature and by performing magnetic induction from the magnetic means through the first leg part to another leg parts. CONSTITUTION:High-permeability armature 5 is provided with the first leg part 6, the second leg part 7a, and the third leg part 7b which extend to three directions, and leg part 6 extends toward the axis of cantilever 1 equipped with stylus 2. Moving coils 3 and 4 are wound around leg parts 7a and 7b respectively. One pole 8a of the magnetic means if arranged adjacently and oppositely to leg prts 6, 7a and 7b of armature 5. In this constitution, when stylus 2 tracks the sound groove of the stereo record recorded by the 45 deg. and -45 deg. system, the stereo signal where horizontal components and vertical components are synthesized is output to coils 3 and 4. |
