Abstract
A micro-electro-mechanical system (MEMS) microphone device is provided in the present disclosure. The MEMS microphone device includes a first electromagnetic shielding cover defining a first accommodating space; a second electromagnetic shielding cover received in the first accommodating space and defining a second accommodating space; a MEMS chip and an application specific integrated circuit (ASIC) chip received in the second accommodating space. The first electromagnetic shielding cover and the second electromagnetic shielding cover cooperatively provide dual electromagnetic shielding protection for the MEMS chip and the ASIC chip.
