Amplifier

An amplifier is like a magic microphone that can make things louder. You plug something like a guitar, a phone, or a music player into the amplifier and it helps them make noise much louder. It's like when you turn up your TV volume to hear your favorite show, but an amplifier is much better than your TV. It can also make the sounds clearer and more powerful. So if you want to hear your music or guitar really loud and clear, an amplifier is what you need!
