摘要： The present invention discloses a method for manufacturing a diaphragm (120) of an acoustic transducer which can cut down a manufacturing cost by reducing waste of a film material, and which can prevent the diaphragm (120) from being eccentrically positioned in the acoustic transducer. The method for manufacturing the diaphragm of the acoustic transducer includes the steps of cutting a polymer film into a size insertable into a molding die, positioning the cut film in the molding die, heating the molding die and pressurizing the film at the same time, cooling the molding die and removing the pressure applied to the film, and separating the molded film from the molding die. An outer guide portion (G) bent in an upward or downward direction is formed at the outer portion of the molded film. The molding die for the manufacturing method can cut down the manufacturing cost by reducing waste of the film material.
