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.

An audio amplifier is a common electronic device used in the music industry and marketplace. It basically takes a weak electronic signal or current and increases its strength. For instance, if you wanted to amplify the weak sounds coming out of your home speakers, you could connect an audio amplifier to your speakers to create the volume of the sound.

The audio amplifier is one of the most critical components of a sound system or a speaker unit, because it performs the major function of sound amplification. These amplifiers simply receive low frequency signals (In the range of 20 Hertz to 20,000 Hertz) and convert them to high frequency signals.
How Does a Car Audio Amplifier Work – The Power Supply
https://www.bestcaraudio.com/how-does-a-car-audio-amplifier-work-the-power-supply/
Since we need an AC signal, modern amplifiers use a pulse-width modulator to create a series of square waves that turn on a bank of MOSFETs (electrically controlled high-current switches) that pulse the supply voltage on and off very quickly. Many high-quality amplifiers have power supplies that switch at more than 300kHz.

Simply put (no tech-speak) it is the job of an amplifier to make sound louder. The input is where the source of the sound is attached, or “fed” to the amplifier. This can be with many types of plugs and devices such as microphones, mixing boards, MP3 players, etc. The output is where the louder sound leaves the amplifier.

Perhaps one of the easiest ways to understand how an analog audio amplifier works is to think of it as a kind of servo-controlled “valve” (the latter is what the Brits call vacuum tubes) that regulates stored up energy from the wall outlet and then releases it …
