Abstract

1332486 Stereophonic pick ups MICRO SEIKO CO Ltd 23 Dec 1970 61161/70 Heading H4J A stereo moving coil pick up has an armature 30 rigidly connected to one end of a cantiliver arm 37 which carries the stylus 38 at its other end. The armature consists of two arms 32, 33 (Fig. 3) each having a coil 35, 36 wound thereon and the arm 37 is attached at a point defined by the intersection of the centre lines of the arms. The armature is resiliently attached to a yoke member 67 by rubber damper 66 and cooperates with a second yoke member 68 all contained in housing 64. The coil ends are connected to female contacts 65 embedded in the housing 64. Co-operating male pins 55 are provided in the block 53 which also houses the permanent magnet 58. When the two housings are engaged as shown in Fig. 5 the poles of the magnet are aligned with the yoke ends and the coupling pins are engaged and locked by projection 70 engaging recess 61. Pins 55 allow the assembly to be connected to the pick up arm. A cover 75 can be turned down to protect the stylus when not in use.
