Abstract

732,422. Gramophone sound-boxes. SCHMIDT, P. July 15, 1953 [Nov. 7, 1952], No. 19674/53. Class 40 (2). In a gramophone sound-box the pivotal axis of the stylus lies within the projected area of the diaphragm. The stylus comprises a member 12 which is held against pivotal points 14, Fig. 4, by a spring 26, Fig. 3, having arms 15 engaging apertures in the member 12. The needle screw 23 grips the needle 8 at the pivotal axis defined by the points 14. The stylus member 12 may be made of synthetic resin material or light metal and is connected by a wire 3 to the diaphragm 1 by means of a synthetic resin adhesive. The stylus member 12 is mounted on a domed member 25 forming part of the casing of the sound-box.
