Intensified field focus moving coil phonocartridge assembly

摘要

The invention is an intensified field focus moving coil phonocartridge assembly (10) including a rear magnet (32) and a front magnet (34) mounted in an axially juxtaposed manner within a support sleeve (38) so as to define therewith a magnetic field chamber (36). A signal coil subassembly (26) is suspended within the field chamber (36) and affixed to a cantilever (24) having a stylus (22) on its opposite end such that vibrations of the stylus (22) are physically translated to the signal coil subassembly (26). Electrical signals generated by the currents induced in the windings (29 and 30) of the signal coil subassembly (26) by induction caused by vibration within the field chamber (36) are carried to signal output pins (18) for electronic processing. The primary usage for the phonocartridge assembly (10) is in high quality stereo phonographic equipment for playing phonograph records.
