PURPOSE:To cancel the magnetic induction current in the armor and improve the transient response characteristic of output signals by connecting in series grounding terminals of output terminal of armors and the internal dynamo- system. CONSTITUTION:Electric connection 8 of the cover 6 as the metal armor with the base of the moving-coil type pick-up cartridge, electric connection 9 of the cover 6 with the front yoke of the internal dynamo-system consisting of the front yoke, magnet, rear yoke, pole piece and armature, and electric connection 10 of the armature with grounding terminal G of the output terminals are made, providing a series connection in the order base 7, cover 6, front yoke, magnet, rear yoke, pole piece, armature and output terminal. The same holds true of moving magnet type pick-up cartridges. |
