Abstract

The present invention provides a MEMS speaker including a substrate sidewall enclosing a cavity. The substrate sidewall includes a first surface and a second surface, a sounding assembly that is arranged on the first surface of the substrate sidewall and also seals the cavity at the opening of the first surface, and a bracket disposed in the cavity. The sounding assembly includes a first sounding assembly and the second sounding assembly. Each sounding assembly includes a driving part and a flexible diaphragm. The flexible diaphragm closes the gap formed between the free ends of adjacent driving parts and between the free ends of the driving parts and the substrate sidewall. The present invention also provides a manufacturing method of MEMS speaker. The MEMS speakers provided by the present invention have high-quality acoustic performance.
