audio amplifier
Volume-increasing device
An audio amplifier is an electronic device that increases the power of audio signals, making sounds louder.
It takes a weak electrical signal—from a microphone, instrument, or playback device—and boosts it enough to drive speakers or headphones.
Amplifiers range from tiny circuits in phones to massive units powering concert halls: The band's audio amplifier blew out mid-song.
