Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Pulling Apart
So the first step is to remove the original speaker casing.
As you can see I used a flat head screw driver to open it up.
MAKE SURE ITS NOT TURNED ON!!
Step 2: The Gear
After all that you should be left with just two speakers and the volume control circuit.
Step 3: Hole Punching
I punched holes in either side of the can where the speakers are going to go. This will ensure that maximum sound will leave the can.
Also punch a hole where the volume knob will go.
Step 4: Speaker Placement
I placed the speaker at the bottom of the can face out. I folded cardboard and duck taped it together to make a spacer so that the speakers would stay in place. Then I put in the foam from the old speakers to act as a dampener.
Step 5: Insulation
I cut out some foam and cardboard to as an insulator between the speakers and the circuit board.
Step 6: Running Cable
Next I cut a hole for the wires to run out of so that the lid could go back on.
Step 7: Turn on and Listen.
Attach volume knob, mount LED and you have successfully made a coffee can sound system.
Just plug it in and enjoy.
