: Logarithmic potentiometers (typically 10k ohm) are used for volume adjustment. Noise Reduction Noise Reduction An audio amplifier takes a weak

An audio amplifier takes a weak electrical signal (from a phone, laptop, or microphone) and uses an external power supply to increase its voltage and current. This allows the signal to drive a speaker, which converts the electrical energy into sound. Key Components for Your Projects How to make an LM386 audio amplifier circuit
