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.

The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package. The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts.

A simple but efficient Audio Amplifier is designed using LM386 Audio Amplifier IC. The working of the circuit is very straight forward as all the work is done by the LM386 IC itself. When the system is powered on and proper audio input is given at the input, the LM386 Amplifier the input signal by a factor of 200 and drives the output speaker.

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 …

(Circuit diagram of an LM386 amplifier with bass boost.) This circuit is capable of providing a bass boost. As you can see, R2 and C2 get connected in series to give a special bass effect. Also, the output gain relies on a bass frequency. In this case, a 25dB gain equates to 100Hz, and a 19dB gain equates to 2kHz. You can also adjust the volume via VR1.

In the first part of lab#1 you will construct a low-power audio amplifier/speaker driver based on the LM386 IC from National Semiconductor. The audio amplifier will be a self-contained, battery-operated component. In the second part of the lab you will construct a microphone circuit using a compact electret condenser microphone cartridge.
