Abstract: A moving iron type cartridge comprising a mounting base, a pair of permanent magnets for right and left channels secured to said mounting base, yokes for the right channel secured on the pole sides of said permanent magnet for the right channel and partially to the mounting base and having a coil wound thereon, yokes for the left channel secured on the pole sides of said permanent magnet for the left channel and partially to the mounting base and having a coil wound thereon, a damper case positioned at the end portions of said yokes and secured to the mounting base, a damper housed in said damper case, and a cantilever secured to said damper and having a stylus fixed to the tip thereof, whereby the stylus replacing operation can be easily performed and the outputs of a high level can be obtained.

Abstract: An improved moving coil-type phonograph cartridge producing reliably higher output and being easily manufactured is provided. Moving coils disposed in the center of a gap in magnetic circuit of permanent magnet and pole pieces is supported rotatably about a fulcrum positioned out of coil bobbin and an axial line of the gap so that coil sections on remote side from the fulcrum will transverse magnetic fluxes in the gap with a larger rotation radius and at a higher velocity than those of the other coil sections on fulcrum side. Further, at least a pole piece on the fulcrum side has a cavity surrounding the fulcrum so that the fluxes will be distributed to be circumferentially away from the fulcrum whereby the coil sections on the fulcrum side will be disposed out of the fluxes. Electromotive force eventually produced in the coil sections on the remote side from the fulcrum is larger than that produced in the other sections so that effectively and reliably higher output can be obtained.
