Abstract

324,826. Gramophone Co., Ltd., (Victor Talking Machine Co.). Feb. 13, 1929. Diaphragms; magnetic instruments. - An acoustic diaphragm 1, Fig. 1, is mounted by means comprising a. plurality of superimposed layers 5, 6, Fig. 2, of woven material, preferably cemented together and with the threads of one layer lying at an acute angle to the threads of another layer. The diaphragm 1, is actuated by a moving coil 2, and is mounted at its smaller end on a pillar 10 projecting from the central magnetic pole 11. The periphery of the diaphragm may also be supported by two annular rings of superimposed layers of woven material cemented together.
