Abstract

277,499. Jaccard, L. E. Sept. 22, 1926. Reproducing and recording devices, arranging and supportinq.-Relates to sound recording or reproducing devices of the kind embodying a conical diaphragm without an amplifying horn. the diaphragm being mounted on an arm which is hinged to a rotatable bracket and supported thereon by a spring-controlled plunger. According to the invention, the bracket, constituted by lugs d between which the diaphragm-carrying arm b is hinged, is supported in a hollow upright f by means of a tubular stem e containing a plunger h and spring i. The plunger has a large head k on which bears a screw g mounted in the arm b. By this means the pressure of the stylus on the record can be regulated.
