Abstract

PURPOSE:To easily manufacture the titled diaphragm having the characteristics of high elasticity and high specific modulus of elasticity by molding the diaphragm from a sheet plate obtained by mixing and kneading a flaky inorganic material with synthetic resin and orienting the inorganic material on the surface of the sheet plate. CONSTITUTION:Flaky talc 1 used as a flaky inorganic material is mixed and kneaded with synthetic resin 2 to form a plate used as a diaphragm for an acoustic device. The average grain diameter of the flaky talc 1 should be about <=20mu and 50-90wt% flaky talc 1 is mixed with 50-10wt% synthetic resin 2. A sheet 3 obtained by mixing and kneading the flaky talc 1 with the synthetic resin 2 is formed like a hone 4 of the acoustic device to oriente the flaky talc 1 along the surface of the hone 4. Thus, hone 4 of high elasticity and high specific modulus of elasticity can be easily manufactured.
