Abstract

1,027,102. Transducers. STANDARD TELEPHONES & CABLES Ltd. Nov. 13, 1964 [Nov. 19, 1963], No. 45598/63. Heading H4J. [Also in Division H1] The stylus of a gramophone pick-up, Fig. 7 (not shown), or the diaphragm or ribbon of a microphone is connected to a pivoted arm 5 carrying a probe 4 which presses on a transistor 2 where its emitter-base junction emerges at the surface. A screw 8 adjusts the static pressure of the probe 4 on the junction, which may be covered with a protective layer of oxide or other material. The metal base-plate 1 has a gold-coated surface in contact with the transistor 2.
