Radio receiver

A radio receiver is a device that can pick up signals that have been sent over the air by radio waves. In other words, radio receivers can "hear" things like your favorite radio station. When you turn on a radio, it sends a message through the air, and the radio receiver picks up that message and plays it through the speakers. So, if you want to listen to music, you can turn on your radio receiver and it will pick up the signals that are being sent and turn them into music for you to enjoy.
