Vibrating diaphragm molding jig and molding method

Abstract

The invention discloses a vibrating diaphragm molding jig for preparing a vibrating diaphragm in a moving-iron telephone receiver. The vibrating diaphragm molding jig comprises a molding plate, at least one groove arranged on the molding plate, wherein the groove is outward bulged from the surface of the molding plate and used for positioning the vibrating diaphragm, and a through hole for suctionvacuum is formed in each groove. On the vibrating diaphragm molding jig, the groove is formed on the molding plate for vibrating diaphragm positioning, and the through hole is formed on the molding plate for sucking the vacuum, the vibrating diaphragm can be tightly adsorbed on the molding plate, and the operation is convenient; this design is simpler on the whole structure and the positioning ismore accurate, simple and practicable in the preparation of the vibrating diaphragm, and the obtained vibrating diaphragm is high in quality; multiple grooves can be formed on the molding plate so asto perform batch production. The invention further provides a vibrating diaphragm molding method using the above vibrating diaphragm molding jig. The vibrating diaphragm molding method disclosed by the invention is simpler on the structure of the molding jig, is more simplified on the steps, is especially accurate on the vibrating diaphragm positioning aspect, and is suitable for the vibrating diaphragm molded in one body.

Description

technical field [0001] The invention relates to the technical field of moving iron receivers, in particular to a diaphragm forming jig and a forming method. Background technique [0002] Moving iron receivers are mainly used in hearing aids, wearable earphones and other equipment to convert voice electrical signals into sound waves. Generally, the electro-acoustic conversion function is realized by using the principle of electromagnetic action, and the diaphragm is an important component to realize the electro-acoustic conversion function. [0003] The traditional diaphragm is generally composed of three parts: the vibrating plate, the film and the forming frame. During the preparation process, the vibrating plate and the forming frame are sprayed with glue, and then the three parts are heated and pressurized. The action and the film are bonded together to form a sandwich-like structure. The jig involved is composed of a pressure block for applying pressure, a heating block...

Problems solved by technology

[0005] Based on this, it is necessary to provide a vibrating film forming method for the jig in the process of preparing the vibrating film, which cannot accurately ensure the consistency of the three parts of the vibrating plate, film and forming frame, so it is difficult to ensure the quality of the vibrating film after forming.
