Problems solved by technology
Although these engineering plastic materials have good temperature resistance, the materials have poor resilience, and the products are prone to film folds, which cannot play a waterproof role.
In particular, the diaphragm made of these engineering plastic materials has poor fatigue resistance and resilience, and the diaphragm cannot maintain excellent elasticity during the long-term vibration process, which can easily cause poor hearing and make the acoustics of the sounding device poor performance
Moreover, the existing diaphragm cannot be used normally under extreme conditions, and has many defects.

Abstract
The invention discloses a vibrating diaphragm for a miniature sound production device and the miniature sound production device. The vibrating diaphragm comprises at least one elastomer layer, and theelastomer layer is made of chloroprene rubber; wherein the chloroprene rubber molecular chain structure comprises isomers of chlorinated butadiene; wherein the molecular weight of the chloroprene rubber is 10000 to 500000. The vibrating diaphragm provided by the invention has excellent elasticity and fatigue resistance.
Description
technical field [0001] The invention relates to the technical field of acoustic devices, and in particular, the invention relates to a diaphragm for a micro sound generating device and the micro sound generating device. Background technique [0002] In recent years, with the rapid development of small electronic devices such as mobile phones and tablet computers, electronic devices need to be equipped with miniature sounding devices with smaller volume and better performance. Diaphragm is one of the very important components in micro-sounding devices. [0003] Existing diaphragms used for miniature sound generating devices are mostly made of high-modulus engineering plastic materials, such as PEEK, PAR, PEI, PI, and the like. Although these engineering plastic materials have good temperature resistance, they have poor resilience, and the products are prone to film folding, which cannot play a waterproof role. In particular, the diaphragm made of these engineering plastic m...
