Abstract

PURPOSE: To manufacture a light diaphragm with a simple method by impregnating a thermosetting resin into edge material as the base material which is cotton fabrics and coating acrylic resin on its one side.
CONSTITUTION: The edge material as the base material which is the cotton fabrics, is impregnated with the phenolic resin of a solidification type, and is dried. Afterwards, the acrylic resin is coated on its one side, and is dried at about 120°C. After punching said edge base material into a prescribed shape, it is simultaneously molded and adhered to a cone part under a condition that a metal mold temperature is 200° and pressing time is 8 seconds to obtain the diaphragm.
