Abstract
A microphone with a combined packaging structure includes: a substrate, a first cover being provided on top of the substrate, the substrate, together with the first cover, forms a first accommodating cavity, an acoustic sensor being provided inside the first accommodating cavity, and an acoustic through-hole being formed in the first accommodating cavity. A second cover is provided on a back face of the substrate, the second cover, together with the substrate, forms a second accommodating cavity, and a proximity sensor is arranged inside the second accommodating cavity. By adopting the above-mentioned technical solutions, the present invention has the beneficial effects that two accommodating cavities are respectively provided on the top and bottom of the substrate in the microphone according to the present invention, for receiving components of a MEMS microphone and the components of a proximity sensor respectively.
