Simple Audio Amplifier : 5 Steps - Instructables

https://www.instructables.com/Simple-audio-amplifier/

Trimmer P1 is for adjusting input power. P1 is not necessary. Capacitor C1 is for filtering DC current out from audio signal. With resistors R1 and R2 we set voltage divider. With voltage divider we set working point of amplifier to half of the supplied voltage (4,5 V in this case). Resistor R3 and trimmer P2 are there to set amplifiers gain.

LM386 IC is a power amplifier used to amplify the small audio signals with the supply of low voltages. Even though internally the gain of IC LM386 is set at 20 but, by adding a resistor and a capacitor at pins 1 and 8 of the IC, we can raise this gain up to 10 times higher than internal gain i.e., up to 200. IC LM386.
