A method for packaging micro electromechanical systems (MEMS) microphone has steps of providing a base, arranging and mounting multiple microphone component assemblies on the base, providing a frame, mounting the frame on the base, forming multiple microphone units, providing a cover; mounting the microphone units on the cover and forming multiple MEMS microphones. Therefore, the MEMS microphones can be produced once in large quantities to save production time and costs.
