Introduction: 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.
