Zusammenfassung: | The invention provides a microphone and an electronic device, and relates to the technical field of microphones, the microphone comprises a substrate and a shell covering the substrate, the substrate and the shell are matched to form a containing cavity, a sound hole is formed in the substrate, a base plate and an MEMS chip are arranged in the containing cavity, an air hole is formed in the base plate, the MEMS chip is installed on the base plate and faces the air hole, and the MEMS chip is installed on the base plate and faces the air hole. The base plate is installed on the substrate to form a diversion channel communicating the air holes and the sound holes, and the air holes and the sound holes are arranged in a staggered manner. According to the microphone, the air holes and the sound holes are arranged in a staggered mode, air entering from the sound holes can enter the air holes after passing through a corner, the speed of airflow can be reduced, the impact effect of the airflow on the MEMS chip is red |
