Abstract
A MEMS microphone for a frame-free device, comprising a substrate, wherein the substrate comprises a first substrate region provided with an acoustic sensor, an ASIC chip, and a MEMS chip, and a second substrate region provided with a plurality of pads; both the first substrate region and the second substrate region are disposed at the same side of the substrate; an acoustic through-hole is disposed at the back of the first substrate region; a microphone connection structure further comprises a flexible circuit board, wherein the flexible circuit board electrically connects the plurality of pads of the MEMS microphone to a circuit board of the frame-free device; the acoustic through-hole is aligned with an acoustic opening of the frame-free device; by adopting the MEMS microphone for a frame-free device, the MEMS microphone may be more widely used in many high-tech industries and has better acoustic performance over the conventional MEMS microphone.
