Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Take a Box, and Prepare to Cut It

you can use different boxes of different size, because the working principle is the same.

the goal is to create a conic structure from your box, using just a cutter and a stapler.

In this instructables I used the boxes of corn flakes and of a fruit juice.

Take your box, clean it eventually, and with the help of a ruler sign the lines that you will follow to cut it.

I'm not giving you any length or size because it depend of your box and your smartphone.

After you cut the top and the 2 sides of the box you can use a stapler to fix it.

Step 2: Paint It and Enjoy It

it's not really necessary, but it could be nice to customize your tool.

I used a spray paint (scientific name aerosol paint ).

Step 3: Final Test

I hope you like my idea, and it will be source of inspiration for all of you.

If you'd like to know if it really works you can watch the video and in the end you will find the test I made.

Of course the improvement of the volume it is not like the electronic solution, but it works, maybe you will not have a disco but if you are in the mountain or at the beach, without electrical sources, with this tool you are going to have a slight but helpful increase of the volume.

have fun !!
