wherein, the voice detection unit detects whether the audio signal is a voice signal, including:
carrying out fast Fourier transform on the audio signal to obtain a frequency domain signal;
calculating a spectral amplitude value according to the frequency domain signal;
calculating probability density according to the spectral amplitude value;
calculating the spectral entropy of the audio signal according to the probability density;
and determining whether the audio signal is a voice signal according to the spectral entropy.
6. The microphone apparatus as defined by claim 5 further comprising:
a living body detection unit for detecting whether a living body user exists around when the voice detection unit detects that the audio signal is the voice signal;
the closing unit is specifically configured to close audio playing of a speaker of the microphone device when the determination result of the determining unit exceeds the set threshold, when the voice detecting unit detects that the audio signal is the voice signal, and when the living body detecting unit detects that a living body user exists around the living body detecting unit.
7. The microphone apparatus according to claim 5 or 6, characterized by further comprising:
the conversion unit is used for converting the audio to be played by the loudspeaker of the microphone device into corresponding text information after the audio playing of the loudspeaker of the microphone device is closed by the closing unit;
and the output unit is used for projecting and displaying the character information.
8. The microphone device as claimed in claim 7, wherein the output unit is specifically configured to detect whether the microphone device is communicatively connected with smart glasses, and if so, transmit the text information to the smart glasses in real time, so that the smart glasses project the text information to eyeballs of a user, so that the user sees the text information.
