How Does Sound Amplifier Work?

Let’s put it straight and simple. Amplifying means to make it sound louder. The noise of the sound depends on how high or low its wave (amplitude) is. Now sound amplifier works by giving that sound wave more energy. And this is performed by using a current.

Amplifier contains a semiconductor for conducting electric current, which is used to increase voltage of the sound. When a sound wave goes through a current to the amplifier, semiconductor boosts the voltage of the audio sound. This makes audio waves higher, so the noise becomes louder.

Examples of Sound Amplifiers
