Description

Technical Field

[0001] The utility model relates to the technical field of diaphragms, in particular to a waterproof diaphragm. Background Art

[0002] The vibrating membrane (diaphragm) in traditional audio equipment is easily affected by moisture, deformation or damage in humid or underwater environments, thus affecting the sound quality and service life. In order to solve this problem, although some waterproof measures have appeared on the market, the effect is often not ideal. Once it encounters water or a humid environment, it is easy to cause the diaphragm to be damaged, affecting the sound effect and even damaging the audio equipment. The replacement of the diaphragm is usually complicated. For this reason, we have proposed a waterproof diaphragm. Utility Model Content
