This circuit is based on LM386 IC to amplify sound. LM386 is a low voltage audio amplifier and frequently used in battery powered music devices like radios, guitars, toys etc. The gain range is 20 to 200 , gain is internally set to 20 (without using external component) but can be increased to 200 by using resistor and capacitor between PIN 1 and 8, or just with a capacitor.

Typically, an LM386 Audio Amplifier Circuit features a default gain of 20. Thus, using it without external components will boost the audio input by twenty-fold. You can, however, increase this voltage gain by adding external components. The maximum possible amplification that you can obtain is 200 times.

Circuit 4, with its relatively large value coupling capacitor, uses the LM386 as both an audio amplifier and RF envelope detector, with both signals appearing at the emitter of the front end transistor. Circuit 5 has a smaller value input coupling capacitor and uses the LM386 as an RF envelope detector, which only detects the RF present on the emitter of the front end …
