How to Make a Simple Smartphone Amplifier

Hey Guys!

First off, thanks for checking out my instructable!

Today I'm going to show you how to make a simple smartphone amplifier!

So lets get started!

Supplies

1.Cardboard Toilet Paper Tube

2.Cardboard

3.Hot Glue and Hot Glue Sticks

4.Scissors or X-acto knife

5.Smartphone

6. Pen or Pencil

So, you want to trace the bottom of your phone (or wherever your smartphones' speaker is), and cut it out. You're phone should fit snug.

I cut out 4 cardboard squares, each being long enough to touch the ground. I then hot glued them onto the tube.

Now just turn up your tunes and jam!

Thanks for viewing this!

Thanks again!
