Sound sensor module voice control switch strength detection audio amplifier microphone LM386

The LM386 is an audio integrated power amplifier with its own low power consumption, adjustable gain for updating the internal chain, wide supply voltage range, fewer external components and less total harmonic distortion. It is mainly used in low-voltage consumer products. In order to minimize the peripheral components, the voltage gain is built-in as 20, and by adding an external resistor and capacitor between pin 1 and pin 8, the voltage gain can be adjusted to any value within 200.
