Abstract
A micro-electro-mechanical system (MEMS) microphone device is provided in the present disclosure. The MEMS microphone device includes a circuit board, an electromagnetic shielding cover mounted on the circuit board to define an accommodating space, electronic components received in the accommodating space and electrically connected to the circuit board, and a metal shielding member disposed between the electronic components and the electromagnetic shielding cover. The electromagnetic shielding cover has an inner surface and an outer surface; and at least one of the inner surface and the outer surface is provided with a first metal shielding layer. At least one of the electromagnetic shielding cover and the metal shielding member is electrically connected to the circuit board.
