Abstract

PURPOSE:To miniaturized the entitled cartridge and strengthen the unification of the cartridge by piling up 2 yorks and a magnetic member vertically, and making the cartridge 3-plate structure. CONSTITUTION:The unit of a moving-type pickup cartridge is composed of a trans ducer structure 11 and a fitting base board 13 with a concave 12 whose surfaces are contacted with both sides and the back side of the structure 11. The front surface of the transducer structure 11 is equipped with a pole piece 24 which is surrounded with a coil 13 and interlocked with the cantilever through a damper 22, a plate-like 1st york 25 unified with the pole pieced 24, a thin plate-like magnetic member 28 adhering and contacting with the upper surface of the 1st york 25, and a plate-like member with a L section. The back part of the structure 11 is equipped with the 2nd york 26 contacted with the upper surface of the magnetic member 28.
