Abstract: A stylus suspension for a phonograph pick-up cartridge. A first improvement includes an asymmetrically mounted ring and washer clamping the suspension block in a manner that dampens vertical compliance of the suspension. A further improvement includes a suspension block specifically adapted to accommodate the ring, thus more particularly defining the pivot point. In this instance the ring may be mounted symmetrically or as in the first improvement. A still further improvement includes an armature of reduced mass that, surprisingly, does not result in lessened performance.

Abstract: A magnetic stereo phonograph pick-up cartidge, including a removable stylus assembly of low mass which includes means for precisely aligning the armature with respect to the pole pieces. A boss on the stylus assembly and a mating aperture on the cartridge body assure alignment in the first instance, and a symmetrical, rubber, armature-pivot block is so positioned that perfect alignment between armature and pole pieces, and a proper tracking angle, are achieved only when the stylus is on a recording. The stylus assembly further includes a permanent magnet for energizing the armature, mounted so as to minimize interaction with the pole pieces and eliminate any distortion of the armature, and so provide a more linear, distortion-free response.
