Silica gel diaphragm forming method and silica gel diaphragm prepared by the method

Abstract

The invention discloses a silica gel vibrating diaphragm forming method and a silica gel vibrating diaphragm prepared by adopting the same. The silica gel vibrating diaphragm forming method comprises the following steps of: providing a hot pressing die and a dome, and placing the dome used as an insert into the hot pressing die; providing liquid silica gel, and injecting the liquid silica gel into the hot pressing die along an edge of the dome; carrying out hot pressing on the liquid silica gel to form a silica gel diaphragm, connecting the silica gel diaphragm with the dome, and carrying out formation to obtain a silica gel diaphragm component; and providing an injection molding machine, placing the silica gel diaphragm component used as an insert into the injection molding machine, carrying out bracket injection molding on the silica gel diaphragm component, connecting a formed bracket to an edge of one end of the silica gel diaphragm, which is far away from the dome, and carrying out formation to obtain the silica gel vibrating diaphragm. The silica gel vibrating diaphragm forming method provided by the invention is simple in process, and the silica gel vibrating diaphragm obtained after formation is excellent in performance.

Description

【Technical field】 [0001] The invention relates to the technical field of electronic products, in particular to a method for forming a silica gel diaphragm and a silica gel diaphragm prepared according to the method. 【Background technique】 [0002] Loudspeakers are widely used in people's daily life as a sound-generating device for electronic devices such as mobile phones and tablets. The loudspeaker includes a vibration system and a magnetic circuit system that drives the vibration system to vibrate, wherein the vibration system includes a diaphragm and a voice coil that drives the diaphragm to vibrate, and the vibration of the diaphragm pushes the surrounding air to vibrate to realize the conversion of electrical signals to acoustic signals. In order to improve the sound reproduction effect and optimize the performance of the product, people have made many attempts and explorations in the structure and materials of the diaphragm, and the application of the silicone diaphrag...

Problems solved by technology

[0004] In the related art, the silicone vibrating membrane includes a connected ball top, a silicone membrane and a bracket. The molding method is usually to mold the components separately and then paste them in sequence, because the silicone membrane is respectively connected to the ball top and the Bracket connection, its shape and size are affected by the shape and size of the dome and the bracket, the process requirements are high, and special and precise design is required to meet the assembly requirements of each component, so that the silicone diaphragm can maintain good performance; Therefore, different silicone film forming molds need to be used for products of different specifications, and the production cost is high.

At the same time, each part has unevenness when pasting, which also affects the performance of the silicone diaphragm
