Abstract
600,172. Moving-coil gramophone pick-ups. PYKE, K. E. M. Sept. 29, 1945, No. 25342. [Class 40 (iv)] A moving-coil gramophone pick-up has a vibrating system comprising an armature 3, carrying a coil 7 and pivoted in rubber end caps 13, which serve to provide damping and restoring forces. The coil 7 is wound through two transverse parallel holes so that its plane lies along the axis of the armature 3, the leads 10 from the coil passing through one of the pivoted ends. The armature 3 is also drilled midway between the pivots and at right angles to the plane of the coil, in order to accommodate the stylus 4, which may be a push fit. A magnetic field is produced across the armature 3 by polepieces 2 and a magnet mounted on a back-plate 5 carrying terminals (i, to which the leads 10 from the coil 7 are connected. In the construction shown in Fig. 13, the armature 3 is mounted in a brass sleeve 15 which is slotted and soldered to the polepieces 2 as shown in Fig. 12.
