Abstract

PURPOSE:To prevent the generation of air bubbles between the adhered surfaces of a diaphragm and a reinforcing plate, by simplifying the process of manufacture by adhering the diaphragm and reinforcing plate simultaneously with the formation of the diaphragm. CONSTITUTION:On the acoustic-radiation-part forming part 4a of a lower die 4, a reinforcing plate 3 whose adhered surface is applied with a prescribed adhesive and dried is mounted, and on it, a forming material 5a is mounted. Further, a forming material 5a is mounted on the edge forming part 4b of the lower die 4 and then an upper die 6 is dropped. The forming materials 5a and 5b are fused by being heated and pressed at prescribed temperature and under prescribed pressure to form the forming parts 4a and 4b into a diaphragm and at the same time, the reinforcing plate 3 is adhered. The process of manufacture of the diaphragm is simplified to eliminate air bubbles generated between the adhered surface of the diaphragm and plate 3.
