Title:
MEMS MICROPHONE AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/000165
Kind Code:
A1
Abstract:
Provided are an MEMS microphone and a mobile terminal. The MEMS microphone comprises an ASIC chip, a first MEMS microphone chip, a second MEMS microphone chip, a housing, and a circuit board. The ASIC chip is connected to the first MEMS microphone chip and the second MEMS microphone chip. The ASIC chip, the first MEMS microphone chip and the second MEMS microphone chip are disposed on the circuit board, The circuit board and the housing form a sealed first cavity and a sealed second cavity. The first cavity is used to accommodate the ASIC chip and the first MEMS microphone chip. The second cavity is used to accommodate the second MEMS microphone chip. The circuit board has a first through hole corresponding to the first MEMS microphone chip and a second through hole corresponding to the second MEMS microphone chip, thereby realizing functions of a conventional microphone and a distance sensor. The above arrangement reduces the space occupied by internal devices of a mobile terminal, thereby reducing costs incurred in purchasing devices.
