Shenyue’s Assignment 9-Speaker

I made these two speakers using different materials.

The first one is made by copper tape and paper index card. I constructed it by sticking a continuous copper tape on the the paper to form multiple squares.

The second one is made by using painting canvas and conductive threads. It is done by hand sewing the conductive thread into random geometric shapes over and over again. It worked when connected to TIP120 and Arduino.
