Abstract

PURPOSE:To constitute a single-piece diaphragm which features the damping effect of higher performance than the sandwich-structure diaphragm, by forming a diaphragm with the mold substance of a sheet of the styrene-group resin plate and having oxidation and burning under the specified conditions. Thus, the productivity as well as the product quality can be enhanced.
