| titleOfInvention | Speaker diaphragm |
| abstract | (57) [Problem] An organic foam as a material replacing paper has advantages and disadvantages such as a low Young's modulus, and a metal diaphragm has a small internal loss and a high density. SOLUTION: An organic fiber is used as a material for increasing the internal loss, and an inorganic filler is used as a material for increasing the Young's modulus. Further, the surface of the diaphragm is hardened by impregnating with an Si-based inorganic impregnating agent and curing by heating. In the papermaking process, a 48% polyester fiber (5 mm length), 4% polyethylene pulp, and 48% sepiolite are made into paper by a wet papermaking method and dried by heating to produce an intermediate product having a predetermined shape. In the processing step, the intermediate product is impregnated with the Si inorganic impregnating agent, heated in a mold to perform primary curing, and finally cured in an electric heating furnace to obtain a desired speaker diaphragm. |
