Speaker in a 9v Case!

I was thinking about a little portable
Speaker to build. But I was thinking
About the enclosure for it, so I came
Up with 9v battery case.

1: dead battery

2: piezo speaker

3: 3.5m audio jack

4: little piece of foam

5: piece of plastic

(Tools)

Soldering iron

Pliers

Super glue

Sand paper

Big cutters

We'll took it out of a pair of old
Headphones, they were broken
So I just cut that piece out.

If you don't have that of foam
Just use a metal grid.

Open Little slabs of metal, get The battery out, should look like this.

Cut the edges of the speaker, so it can fit

Solder the speaker to the audio jack.

Use the big scissors cut the plastic.
Then cut in half.

Super glue the speaker in the middle of the case.

Cut the foam the with big scissors,
To fit in the case. Then Superglue foam in case.

Solder a hole for the audio jack on the
Plastic. Then fit in the case.

It sounds okay but portable
