Abstract
PURPOSE:To facilitate the molding of the diaphragm and to reduce manufacture cost by putting an air-permeable fibrous substrate on a fibrous substrate impregnated with thermosetting resin and performing heat press molding. CONSTITUTION:The fibrous substrate 1a impregnated with the thermosetting resin is put on the top side of the fibrous substrate 2a with air permeability and the both are clamped between metallic molds 3 and 4 and heat molding is carried out for a time and at temperature matching with the curing conditions of the thermosetting resin. Consequently, the top side of the fibrous substrate 1a is converted with the resin which is molten temporarily to form the hard surface which has good sound radiation characteristics and no air permeability, and two substrate 1a and 2a are put one over the other to easily obtain desired thickness and also desired rigidity by the multiplication of the hardness of the curing resin while having proper internal loss, thereby displaying superior characteristics. consequently, the material impregnated with the thermosetting resin is easily heat-pressed and molded.
