1. 3mm Wood Board x1

2. Ruler x1

3. Marker x1

4. Hot Glue Gun x1

The gap in second square is for you to put the cellphone inside, if your phone is bigger than that, try to sketch in a bigger dimension.

Let's try it!

Now, you can put your phone into the speaker, you'll have louder sound and better quality than before.
