How Does Sound Amplifier Work?

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.
