    摘要： A moving coil type pick up capsule having a body, cantilever having first and second ends, a stylus located at its first end and a coil located at its second end and, therebetween, a dampener having an opening therethrough. The cantilever passes through the dampener opening such that the stylus is on a first side of the dampener and the coil is on a second side of the dampener. First and second magnets or yokes are positioned within or proximate the capsule body and spaced from one another to create a gap, the dampener and coil being positioned within the gap such that the fulcrum is located between the stylus and coil and specifically at the dampener. A dampening fluid fills the gap to complete the assembly.

    摘要： In a stereo pick-up having movable coils (14) and an SmCo magnet (22) with a high energy content, with the coil system (14, 15, 18) arranged in front of one pole face of said magnet, a yoke plate (23) of a magnetic soft material is arranged in front of said system to increase the magnetic induction in the coils. The great coercive force of the magnet is utilized for simplifying and reducing the costs of the mechanical structure in that the yoke plate is formed with two legs (26) which extend rearwardly, engage and are secured to two opposite sides of the magnet. The short-circuit of the magnet established by these legs has no noticeable impact on the induction in the air gap because of the high coercive force of the magnet. The manufacturing costs of the magnet system are additionally reduced in that, instead of a hole to receive a mounting assembly (16) for the coil system, the magnet, whose material is very hard, is formed in its underside with a slot (30) in whose bottom the mounting assembly is arranged and secured by means of a plate-shaped projection (31) on a casing member (32) of plastics.

    摘要： A reproducing stylus traces a track of a recording medium, in which track an information signal is recorded as variations of geometrical shape, and reproduces as variations in capacitance the information signal thus recorded. The reproducing stylus comprises a reproducing stylus main structure having a tip part with a flat sliding contact face for slidingly contacting a plurality of track of the recording medium at a time, and an electrode secured to the reproducing stylus main structre at the tip part thereof and adapted to trace one track and reproduce the information signal as the variations in capacitance in accordance with the variations in geometrical shape. The electrode has over a specific distance over the tip part of the stylus main structure from the extreme tip thereof, a constant width in the width direction of the track which is less than the width of the track. The extreme tip of the electrode has a flat or linear tip end contacting the track.
