Speaker in a 9v Case!

Intro: 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.

STEP 1: Parts and Tools.

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

STEP 2: We're I Got My Little Piece of Foam.

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.

STEP 3: Get the Battery Case

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

STEP 4: Fit the Speaker

Cut the edges of the speaker, so it can fit

STEP 5: Connect to Audio Jack

Solder the speaker to the audio jack.

STEP 6: Put Together the Casing

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

STEP 7: Glue the Speaker in the Case

Super glue the speaker in the middle of the case.

STEP 8: Cutting the Foam

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

STEP 9: Make Hole for Audio Jack

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

STEP 10: Listen

It sounds okay but portable

Very clever, and so small! I love the use of 9v battery, and I'm impressed that you could fit a whole speaker inside of it.

We'll it was a piezo speaker
Of course, so it can fit
If I trim it and I did, and it
Fits good. It's not really loud but sounds good.
