Abstract
909,598. Stereophonic pick-ups. RADIO CORPORATION OF AMERICA. Feb. 13, 1959 [Aug. 6, 1958], No. 43113/60. Divided out of 909,597. Class 40 (4). A single crystalline transducing member is common to the two transducing elements of a stereophonic pick-up. The stylus arm is coupled to the elements by a yoke with divergent arms. In one arrangement, Figs. 2, 4, the member 24 which may be of Rochelle Salt or of barium strontium titanate carries a pair of silvered electrodes 24a, 24b on one surface and a common electrode 33 on the other. The member 24 is clamped by a pair of damping blocks 26, 28. The transducing elements are coupled to the stylus arm 38 by a yoke 30. In another arrangement, Fig. 5, two electrodes 50a, 50b adjoin along the longitudinal axis of the rectangular member 50. The other face carries an electrode 50c common to the two elements. The member is mounted in resilient blocks 54, 56 which are maintained under pressure in the pick-up casing. In both embodiments, the stylus arm 38 is mounted in a resilient block 42.
