摘要： PROBLEM TO BE SOLVED: To provide a diaphragm which is easily manufactured and has satisfactory characteristics.
SOLUTION: At least any one kind of fiber material of wooden pulp, chemical fiber and inorganic fiber, a foaming agent and a fine fiber-like binding material of high beating degree are blended as necessary to prepare a paper making material and make paper. A molded object after paper making is attached in the inside of the die of a drying apparatus having a gap corresponding to the shape of a diaphragm 400, and the object is heated and dried so that one part of a vibrating portion 420 becomes thick, thereby forming a foaming thick portion 421 and a non-foaming portion 422. By improvement in bending rigidity by thickness by foaming and improvement in strength by tangling of fibers by fine fiber-like binding material, the diaphragm can be partially reinforced in a state of even weight by preventing increase in weight without reinforcement such as lamination of a different sheet-like member or impregnation of a composite resin, and frequency characteristic is flattened and satisfactory acoustic characteristic can be obtained.

A molded object after paper making is attached in the inside of a die of a drying apparatus having a gap corresponding to the shape of a diaphragm 400, and the object is heated and dried to be foamed so that an edge 430 becomes thick. By improvement in rigidity by thickness by foaming and tangling between fibers by the fine fiber-like binding agent, the strength of the edge 430 can be improved without increasing the minimum resonant frequency without reinforcement such as lamination of a different sheet-like member or impregnation of a composite resin, and a satisfactory acoustic characteristic can be obtained.
