Patent ID: 7923791

Claim:
A package of a MEMS microphone, comprising: a substrate having at least a conductive layer and at least a dielectric layer disposed on the substrate; a MEMS microphone disposed on a bottom surface of the substrate, and electrically connected to the conductive layer of the substrate; a conductive sealing element arranged on the bottom surface of the substrate, electrically and directly connected to the conductive layer on the bottom surface of the substrate, physically apart from the MEMS microphone, and surrounding the MEMS microphone; at least a conductive connecting element arranged on the bottom surface of the substrate and physically apart from the conductive sealing element and the MEMS microphone, and surrounded by the conductive sealing element; and at least an acoustic hole arranged on the substrate, wherein the acoustic hole has a metal layer on an inner wall thereof, and the acoustic hole passes through the substrate and is connected to the conductive layer of the substrate, wherein when the substrate is mounted on a printed circuit board by the conductive sealing element and the conductive connecting element, the conductive sealing element is electrically and directly connected to a conductive layer of the printed circuit board to construct an acoustic housing enclosing the MEMS microphone and the conductive connecting element.
