Abstract
A directional microphone module is disclosed. The directional microphone module includes a sound-permeable mesh, a housing having a top wall and a side wall, a circuit board, and a MEMS microphone fixed to the circuit board. The circuit board and the top wall are spaced for forming a first cavity. The circuit board and the sound-permeable mesh are spaced for forming a second cavity. The two cavities are only communicated at a side, and the MEMS microphone locates at an opposite side. The MEMS microphone includes two acoustic holes, the first one faces the top wall and communicates with the first cavity, the second one faces the circuit board and communicates with the second cavity through a through hole of the circuit board. The directional microphone module can always work stably and has a simple structure, and also can improve the production efficiency and reduce the labor cost.
