How do amplifiers work? - BBC Science Focus Magazine
https://www.sciencefocus.com/science/how-do-amplifiers-work/
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 is sent directly to the power supply within the amplifier.
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” …
How does an audio amplifier work? - Quora
https://www.quora.com/How-does-an-audio-amplifier-work
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.
How a Class D "Digital" Amplifier Works | Audioholics
https://www.audioholics.com/audio-amplifier/class-d-digital-amplifier
What does that mean? 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 in measured amounts to your loudspeakers.

The LM380 is an audio power amplifier for consumer application. Its internal gain is fixed to 14dB in order to keep the system cost minimum. A unique input stage allows inputs to be referenced with the ground. The output gets automatically self-centered to …
How Do Speakers Work? A Super Speaker Guide With …
https://soundcertified.com/how-do-speakers-work/
A stereo or amplifier drives the speaker with an electrical signal that alternates from positive to negative in the shape of the musical signal. As it does so, electric current flows through the speaker’s voice coil, creating a magnetic field that causes it to move toward or away from the magnet as it changes from positive to negative.
