Abstract

836,675. Gramophone pick-ups. DE VRIES, M. March. 25, 1958 [Oct. 29, 1957], No. 9586/58. Class 40 (4). In a pick-up comprising two piezo-electric transducers 3, 4 secured between moulded casing portions 1, 2 by resilient bands 5, 6 and separated by a metal partition 7 which functions as a common electrode, a cantilever stylus arm 11 is connected to the free ends of the transducers by an integral resilient coupling member made, for example, of P.V.C. and comprising arms 21-24, an intermediate section 25 and sleeves 19, 20 surrounding the free ends of the transducers. The angular connections between the arms are arranged to be the most resilient parts of the coupling member so that they constitute virtual pivots, and the linkage thus provided between the stylus 12 and the transducers enables oscillations recorded in the walls of a 90-degree angled groove to be selectively applied to respective transducers for the purpose of stereophonic reproduction.
