Hi everyone! I made three variations of paper speaker with different thickness of paper sheets and spiral forms to see how they work. This is the result!
Material : three types of paper (with different thickness)/copper tape
1. Paper thickness : high / copper spiral density : high
This is is loudest speaker of all three.
2. Paper thickness : medium / copper spiral density : medium
I moved the speaker away from the magnets to see how the speaker works at the greatest extent point.
3. Paper thickness : low / copper spiral density : low
This one didn’t work quite well. I can barely hear the sound from the speaker.
