SPEAKER DIAPHRAGM, SPEAKER USING SAID DIAPHRAGM, AND SPEAKER DIAPHRAGM MANUFACTURING METHOD

摘要

Disclosed in the present invention is a speaker diaphragm equipped with a woven fabric layer impregnated with a thermosetting resin that is thermally cured and a paper layer integrated by being laminated on the back side of the woven fabric layer. Since the fluff of the paper layer filling the mesh of the woven fabric layer intertwines with the yarns of the woven fabric layer from the front surface side of the woven fabric layer and is fixed by the thermosetting resin, the paper layer fills and is integrated into the mesh of the woven fabric layer so that the internal loss and the Young's modulus of the speaker diaphragm can be increased. As a result, the sound quality of the speaker can be improved.
