An amplifier (often loosely called an "amp") is an electromagnetic or electronic component that boosts an electric current. If you wear a hearing aid, you'll know it uses a microphone to pick up sounds from the world around you and convert them into a fluctuating electric current (a signal) that constantly changes in strength.

How Amplifiers Work To understand how audio amplifiers work, you must understand sound from a natural perspective. Whenever sound is produced, it causes vibrations to travel through the environment. Small particles of air surround these vibrations, pushing other air particles out of their way.

An amplifier receives an input signal from a source (mobile device, turntable, CD/DVD/media player, etc.) and creates an enlarged replica of the original smaller signal. The power required to do this comes from the 110-volt wall receptacle.

An amplifier takes an input signal from a source, such as a laptop, turntable or CD player, and creates a larger copy of the original signal before it’s sent to the speakers. Advertisement It gets the power to do this from your mains electricity, which …
How does an audio amplifier work? - Quora

A typical audio power amplifier consists of 3 stages: A differential input stage. This stage usually has no voltage or current gain. It consists of some signal conditioning and a differential amplifier that integrates negative feedback from the output stage to the input signal to increase linearity and reduce harmonic distortion.
What Are Stereo Amplifiers and How Do They Work ...
https://www.audioreputation.com/what-are-stereo-amplifiers/
Stereo amplifiers have 3 ports/connectors (input port for connecting the signal source, the output port that’s used to send the signal to the speakers and power source connector or power input). These amplifiers receive power from the wall socket and they convert alternating current to the direct current thanks to the device called transistor.

Answer (1 of 7): The amplifier can be split into essentially three conceptual sections (although the actual implementation might merge two sections into one physical circuit block). Firstly, the amplifier doesn't want to load down the source of the incoming voltage, so …

A straightforward analog implementation of an audio amplifier uses transistors in linear mode to create an output voltage that is a scaled copy of the input voltage. The forward voltage gain is usually high (at least 40 dB). If the forward gain is part of a feedback loop, the overall loop gain will also be high.
