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.
We have a be nice policy.
