radio receiver
Definition
Noun: 1. An electronic device that receives radio waves and converts them into audible sound or other usable forms of information: A radio receiver is a piece of equipment designed to pick up radio frequency signals transmitted from a broadcasting station, process (demodulate and amplify) them, and output the information, typically as sound through a speaker.
