Abstract

PURPOSE:To obtain a high output and to simplify the manufacturig process, by the construction that a magnetomotive force of a short circuit coil which is driven with the movement of a stylus racting a record disc is picked up from the winding of a magnetic circuit inserting the short circuit coil. CONSTITUTION:A stylus 10 of a cartridge 100 provides a cantilever 11 and a chip 12, and an end 11A opposite to the lever 11 is inserted and fixed to a hole 20A of an armature support 20. The support 20 is formed with plastic and hoes 20B, B' at open leg with almost 90 deg. are inserted with a projection of a coil bobbin 21. A short circuit coil 22 is wound on the bobbin 21. One end of a pole piece 31 of a magnetic circuit 30 is inserted in the inside of the bobbin 21 and another end is provided with an alignment projection 31B. The coil 22 is movably inserted to holes 32A, A' of a front yoke 32 and a nonmagnetic spacer 32C is provided. A base material 40 made of plastic is aligned with a block 14, and the output of the cartridge is picked up from windings 36, 36' of a piece 31.
