Antique radio is a really old radio that people used to use a long time ago to listen to music, news, and stories from far away places. It's called an "antique" because it's very, very old and not something you can find in stores today.
The way this radio works is that it uses something called "radio waves" to pick up sounds and bring them into the radio. Radio waves are all around us, like invisible waves in the air that we can't see. The radio has a special part inside of it called a "tuner" that helps it pick up specific radio waves that have sounds and voices in them.
Once the radio has picked up the radio waves with the sounds and voices, it uses something called a "speaker" to play those sounds out loud for everyone around to hear. Speakers are like little machines that take the sounds and make them louder so that they can be heard by lots of people.
Antique radios are very special because they look different from the radios we use today. They were made a long time ago when people liked things to be shiny and pretty, and so they often have a shiny wooden or metal exterior with lots of intricate designs and details. They're also special because they remind us of a time when listening to the radio was a really big deal and people sat around it to hear the latest news or music.
