Abstract

PURPOSE:To secure a free selection of the form as well as facilitate an easy forming of the speaker diaphragm, by producing the diaphragm via the injection molding method of the plastics. CONSTITUTION:The molding cavity K is blocked through the combination and coupling among the molding tools 1-3. And then the fused resin is supplied to the cavity via the sprue 31, runner 32 and gate 33 each. Then the release is carried out from the mold after giving the curing within the mold. And then the runner 32 is cut off from the speaker diaphragm obtained through the release from the mold.
