METHOD OF ASSEMBLING A DIAPHRAGM ASSEMBLY FOR AN ELECTRO-ACOUSTIC TRANSDUCER

摘要

In assembling at least one metal frame in abutting supporting relation to a diaphragm assembly for an electro-acoustic transducer, the diaphragm(1) is formed in part of a thermoplastic resin so as to provide the latter at each surface of the diaphragm. The frame or frames(2,3) and the diaphragm are pressed together in the desired abutting supporting relation while each metal frame is heated so that heat is transmitted through the latter to melt the thermoplastic resin at the engaged surface of the diaphragm and frames.
