  • Microphone and method for processing audio signals
    Patent number: 10841680
    Abstract: The present disclosure provides a microphone including a main body, where an audio signal is generated in the main body based on the sound level and some other properties received, and an amplifier disposed in the main body, where the amplifier is adapted to amplify the audio signal, with the amplifier able to be configured with multiple gain levels. The present disclosure further provides a method for processing audio signals including: acquiring an audio signal; selecting a gain from multiple gain levels of an amplifier based on a property of the acquired audio signal, where the amplifier is built in a main body of a microphone; and modifying the digital representation after analog to digital conversion of the acquired audio signal according to the selected gain.
