Abstract
The present disclosure discloses a MEMS speaker including a housing with a receiving space; a MEMS speaker chip with an inner cavity, accommodated in the receiving space and connected with the housing, the MEMS speaker chip dividing the receiving space into a first cavity and a second cavity communicating with the inner cavity; a sound hole communicating with the first cavity or the second cavity; and a damping mesh connected to the housing and covering the sound hole; wherein sounds emitted by the MEMS speaker chip transmit outward through the sound hole and the damping mesh. Compared with the related art, MEMS speaker disclosed by the present disclosure has a better reliability.
