MIC is an electret microphone, which senses the weak vibration of sound waves in the air and outputs an electrical signal that follows the same law of sound changes. This circuit diagram uses a microphone with high sensitivity, which can generally output an audio signal of more than tens of millivolts, which is enough to modulate the frequency of the next-level high-frequency oscillation signal.
