Abstract

The invention provides a vibrating diaphragm, which comprises a vibrating part and a plurality of supporting parts connected with the vibrating part, wherein the peripheries of self-vibrating parts of the supporting parts extend outwards. The vibrating diaphragm also comprises at least one central line, and all the supporting parts are positioned on the same side of the central line. The vibrating diaphragm can improve sensibility.

Description

technical field [0001] The invention relates to a vibrating membrane and a microphone comprising the vibrating membrane. Background technique [0002] With the development of wireless communication, there are more and more mobile phone users around the world. The requirements of users for mobile phones are not only satisfied with calls, but also to be able to provide high-quality call effects. Especially the current development of mobile multimedia technology, the mobile phone Call quality is more important. The microphone of a mobile phone is used as a voice pick-up device for the mobile phone, and its design directly affects the call quality. [0003] Micro-Electro-Mechanical-System Microphone (MEMS for short) is currently the most widely used microphone with better performance. In related technologies, a silicon capacitor microphone includes a substrate, a back plate and a diaphragm. Among them, the diaphragm is an important part of the silicon condenser microphone, and ...
