Abstract
A MEMS loudspeaker manufacturing method and a MEMS loudspeaker are provided. The MEMS loudspeaker manufacturing method includes positioning a printed circuit board (PCB) substrate, inverting a MEMS chip and electrically connecting the PCB substrate to a first side of the PCB substrate having a first groove. filling and solidifying a polymer protection material in the gap between the MEMS chip and the PCB substrate, and combining the MEMS chip and the PCB substrate into a combination component. Since the PCB substrate and the MEMS chip are combined into the combination component through using the polymer protection component made of the polymer protection material, and the polymer protection component is coated with the conducting component, an overall packaging size of the MEMS loudspeaker basically is enabled to be consistent with a size of the MEMS chip, and sensitivity parameters of the MEMS loudspeaker may be significantly improved.
