Abstract

PURPOSE:To improve the power generation efficiency of pickup cartridge, by enabling to induce a voltage at the upper and lower sides of the coil at the end of cuntilever. CONSTITUTION:At the end of the cuntilever 2 where the stylus 1 is fixed to the tip, the coil 3L of L channel and the coil 3R of R channel in which the windings are wound in ellipse form so that they are in agreement with the shaft center of the lever 2, are fixed via the nonmagnetic member. The coil (not shown) is fixed to the stylus 1 as 45 deg. so that it can be located in the same plane orthogonal to the axial center of the lever 2. Further, the end of the lever 2 is pressed with the piano wire 4 to enable the oscillation of the coils 3L, 3R themselves by taking the common center A as a fulcrum. The N pole side of the magnets 5L1, 5L2 and 5L3, 5L4 is fixed to the central yokes 6L1, 6L2 and the external S pole is respectively fixed to the front yokes 7L1, 7L2 and the rear yokes 8L1, 8L2 respectively. Further, a voltage can be introduced in the coils 3L, 3R to make excellent the power generating efficiency.
