Abstract

316,007. Welch, A. P. July 23, 1928. Diaphragms ; loud-speakers.-The conical diaphragm a of a loud-speaker is supported at a plurality of points lying in a plane at right angles to the axis of the diaphragm and passing through the centre of gravity, or approximately so, by a number of threads c of the triangular formation shown. Springs g may be provided in the sides of each triangle as shown in Fig. 3 and the tension adjusted by means of a screwed rod h acting on the base of the triangle.
