Abstract

103,335. Chalmers, T. Jan. 24, 1916. Diaphragms. - The diaphragm of a telephone, microphone. gramophone, &c., is provided on one or both sides with a series of thickenings or attachments arranged at equal distances from the centre. The attachments b are approximately semicircular in shape, as shown in Fig. 1, with the curve of their outer faces struck from the diaphragm centre. The thickening may be integral with the diaphragm, and may be formed by pressing out a portion b of the diaphragm and filling in the resulting recess f with solder &c., as shown in Fig. 6. The attachments may be secured by screws c and may be composed of metal, wood, fibre, ebonite, vulcanite, &c.
