Abstract
A photoelectric MEMS microphone and an electronic device, have an acoustic cavity, the acoustic cavity includes a MEMS transducer, configured for capturing an acoustic signal, a signal processing chip, connected to a signal output terminal of the MEMS transducer. The signal processing chip includes a signal output terminal pin and a ground pin, and a light emitting device, a driving terminal of the light emitting device being connected to the signal output terminal pin. The light emitting device packaged in the microphone cavity provides the user indication that the microphone of the terminal device is turned on, avoiding the exposure of personal privacy. Furthermore, it helps to reduce costs in that the signal output terminal pin and the ground pin are integrated into the microphone.
