Abstract

324,344. Woodroffe, J. B. Oct. 22, 1928. Gramophone pick-ups; magnetic instruments.- The armature of a soundreproducer is damped by adjustable pressure of a plurality of rubber or like elements located, along its length. In the gramophone pick - up shown in Fig. 1, the vibratory part 5 is pivoted at 6 and damping members 11, e.g. rubber tubes, attached to a plate 15 integral with the rod 16 are adjusted by the screw 20. Specification 289,161 is referred to.
