Problems solved by technology

At the location of stress concentration, the diaphragm is not only prone to deformation but also prone to rupture, resulting in deterioration of the acoustic performance of the diaphragm or complete failure of the diaphragm as a whole
Moreover, the high temperature resistance of the conventional diaphragm is poor. In harsh environments, the material performance decreases and the vibration state becomes worse.
[0005] It can be seen that the overall performance of the above-mentioned diaphragm is poor, and cannot meet the overall performance requirements of the miniature sounding device

Abstract

The invention discloses a vibrating diaphragm for a miniature sound production device and the miniature sound production device. The vibrating diaphragm is made of fluororubber. A main chain and / or aside chain of a molecular chain of the fluororubber contain / contains fluorine molecules. A vulcanizing agent is mixed in the fluororubber, a molecular chain of the fluororubber forms a cross-linked structure, the thermal deformation temperature of the vibrating diaphragm prepared from the fluororubber is greater than 200 DEG C, and the fluororubber comprises at least one of fluororubber 23, fluororubber 26, fluororubber 246, fluororubber TP, metafluoroether rubber and perfluoroether rubber; the vibrating diaphragm provided by the invention has better structural stability, polarization resistance and low-frequency sensitivity; the miniature sound production device provided by the invention has better acoustic performance.

Description

technical field [0001] The invention relates to the technical field of electronic products, and in particular, the invention relates to a diaphragm used for a miniature sound generating device and the miniature sound generating device. Background technique [0002] With the advancement of science and technology, the application of electronic products is becoming more and more extensive, especially the increasingly miniaturized personal consumer electronics markets such as smart phones, tablet computers, and smart watches are becoming more and more popular. Consequently, there is an increasing demand for miniature sound generating devices used in personal consumer electronics products. [0003] In the existing miniature sound generating devices, single-layer or multi-layer composite engineering plastics or thermoplastic elastomers are mostly used as the diaphragm material. It plays the role of supporting the vibrating part and providing elasticity. However, due to the limit...
