Discover the Speaker!
A Speaker is used for turning electric signals into sound you can hear.
A speaker works like headphones, but bigger. Electric signals from your music player flow through a coil of wire attached to a cone, sitting next to a magnet. The changing signal makes the coil and cone push in and out very fast, and these vibrations push the air to make sound waves. Big cones make deep bass sounds, small ones make high sounds.
Speakers are inside phones, TVs, laptops, cars and doorbells. Concerts and stadiums use huge stacks of speakers so thousands of people can hear, and smart speakers in homes can answer questions and play music when you ask.
What is a Speaker used for?
Play some music and let children gently feel a speaker vibrate, then draw sound waves coming out of it.
If you have a smart speaker at home, ask it a simple question together and talk about how it can talk back.
