A MEMS microphone package includes a substrate including a base layer, a sound hole cut through the base layer, a conduction part arranged on the base layer, a sidewall connected with one end thereof to the top surface of the base layer and having a conducting line electrically connected to the conduction part, a cover plate connected to an opposite end of the sidewall and having a solder pad and a third contact disposed in conduction with the solder pad and electrically connected to the conducting line, an acoustic wave sensor mounted on the top surface of the base layer to face toward the sound hole, a processor chip mounted on the top surface of the base layer and electrically connected to the acoustic wave sensor and the conduction part, and one or multiple electronic components electrically bonded to the cover plate.
