How Audio Amplifiers work: To better understand how an audio amplifier works, let’s take a look at the components used in it one by one. Amplifiers consists of two types of components: The input stage which takes inputs from an instrument; and the output stage which sends the amplified signal to speakers.

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 amplifier basically boosts the signal that is sent to the speakers while keeping the content of the sounds …

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. It gets the power to do this from your mains electricity, which is …

EETimes - How Class D audio amplifiers work
https://www.eetimes.com/how-class-d-audio-amplifiers-work/
It is common in Class D amplifiers to use feedback to compensate for the bus voltage variations. Energy Flow – In linear amplifiers the energy flow is always from supply to the load, and in Full bridge Class D amplifiers this is also true. A half-bridge Class D amplifier however is different, as the energy flow can be bi-directional, which leads to the “Bus pumping” …

In an amplifier, a large current is directed through the transistor (in one lead and out the second). The third lead is connected to the weak signal you wish to amplify. When this signal is slightly larger, the switch is closed and the large current flows from lead 1 to lead 2.

https://www.analog.com/en/analog-dialogue/articles/class-d-audio-amplifiers.html
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. Feedback is often used because high loop gain improves …
