Okay, kiddo! *adjusts glasses* Consumer electronics are the things we buy that help us do stuff, like play games, take pictures, listen to music and more!
You know your tablet, your phone, your game console, your latest toy robot? They are all examples of consumer electronics.
People use these things to communicate with each other, to learn, to relax, and even to work. They are convenient because they are easy to use and portable.
Consumer electronics companies invent and design these gadgets and then sell them to us, their consumers. They make them better and cooler each year. So, in a nutshell, consumer electronics are machines that help us do lots of fun and useful things!
