Example Embodiment

[0027] See figure 1 and figure 2 , The microphone diaphragm 1 of the present invention includes a diaphragm ring (not shown in the figure) and a film 2 glued on the diaphragm ring. The diaphragm 2 is pasted on the metal diaphragm through a specific process method (see below for details), and then Punch out the membrane ring with membrane 2 pasted from the metal membrane plate. The diaphragm 1 requires good electrical conductivity and adhesive strength between the diaphragm 2 and the metal diaphragm to ensure that the diaphragm 2 has a high level of flatness, and realizes arraying and high-efficiency production. The specific steps for manufacturing the above-mentioned diaphragm 1 are as follows:

[0028] (1) Firstly, the metal strip 3 with a certain thickness, which can be used to make the membrane ring, is appropriately slit to divide into metal strips of certain size (not marked in the figure), and then precision leveled.

[0029] (2) The metal strip is divided into strips, and ...

Abstract

The invention provides a manufacturing method of a microphone vibration membrane, which has the concrete steps that (1) a proper metal material belt is selected for carrying on that a whole plate impacts an inner hole of a membrane ring, and a whole piece of a membrane plate is formed after blanking, (2) an adhesive, which is used for sticking a membrame, and is printed at peripheries of the inner hole on the surface of the membrane plate, (3) the surface of the membrane plate, which is stuck with the adhesive, is covered with a membrane, and is planished. After the membrane plate is pressed to thin, the adhesive is solidified, and has electrical conductivity, (4) through adopting that a stamping mould impacts for an outer diameter of the membrane ring for making the emebrane ring which is adhered to the membrane dropped from the membrane plate, so that the vibration membrane used in a microphone is obtained, and the vibration membrane is collected at last. By using the manufacturing method of the microphone vibration membrane, the invention has high production efficiency, damages of the membrane can not appear, and the problem that product property parameters are not uniform can not also occur.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing components in an electroacoustic device, in particular to a method for manufacturing a microphone diaphragm. 【Background technique】 [0002] In the electro-acoustic industry, the microphone is usually stacked by dust-proof net, shell, diaphragm, gasket, back electrode, cavity, copper ring, circuit board, impedance conversion part, etc., and then packaged by edge-sealing process of. Among them, the diaphragm and the diaphragm ring that make up the diaphragm are bonded together by a special adhesive to form a whole, and its manufacturing process is segmented processing, as follows: [0003] (1) Stamping to make film rings: put metal strips (copper or other metal alloys) in a stamping die and stamp them into ring-shaped metal sheets as film rings. The inner diameter and outer diameter of the membrane ring are determined according to product requirements. [0004] (2) Adhesive film ring: After the si...
