ML-01G and LM386 connected application circuit (voice playback)

The picture shows the schematic diagram of the circuit with LM386 power amplifier. The resistance value of the trimpot VR in the picture is 10kΩ, which is used to adjust the output volume. The output power of LM386 is 500mW～800mW. R2 and C3 form a high-pass filter circuit. To improve sound quality. C4 is a 220μ electrolytic capacitor. After the circuit is made, the entire circuit board can be placed in the speaker box for fixed installation.
