Heylo People, in this Instructable, I made a very simple, cheap speaker. For me, it's kinda useful. Check it out!

Step 1: Preparing...

What you need is just a regular things, which are:

1 Cardboard from Wrapping Food Plastic

2 Glass Cups

Step 2: Cutting...

Cut a rectangle hole at the middle of the cardboard, its for your smartphone as the input. Then make a hole in each cup, so the cardboard can be plugged in.

Step 3: Finishing...

Plug all the materials. Then try to plug your smartphone. If its not so perfect, try to adjust the size of the holes and the cup directions. Done.

<p>Awesome</p>
