Sound is made when an object vibrates. The vibrations enter your ear and make your eardrum vibrate. This sends a message to your brain which turns them into the sounds that you can hear.
You may need an adult to help with parts of this activity
To make your speakers the first thing that you need to do is draw around the end of the kitchen roll tube on the side of the paper cups. You can then cut this hole out on both paper cups.
In the centre of the kitchen roll tube you are then going to cut a slit that is big enough for your mobile phone or tablet to fit in. It might help if you draw around your device so that you know how big a slit to cut
You can now fit each end of the kitchen roll tube into the hole that you cut in the paper cups. You may need to tape the kitchen roll in place if the fit is loose
Your speaker is now ready to test...
The way the speaker works is that when you add a phone or tablet, it amplifies the sound by directing the sound waves out at a different angle. It creates a funnelling effect. It you think about a megaphone it works in a similar way to may the sound come out louder.
The video tutorial for this activity is available on the Surrey Libraries Facebook Page or the Surrey Libraries YouTube Channel
