Abstract

PURPOSE:To make a stable-quality speaker in a simple manufacturing process, by forming a body part and an edge part into one body by a polymer graphite and giving proper phisical properties to the edge part by the solvent treatment. CONSTITUTION:After an body part and an edge part are formed into one body with the polymer graphite consisting of a polymer such as polyvinyl chloride and graphite to obtain a diaphragm 1, the edge part 4 is immersed in a solvent tank A containing a solvent which swells or dissolves the resin of main components of the polymer graphite such as butyl acetate, or is treated with a spray B to adjust phisical properties.
