Jillie makes a speaker with a CD case.

This was for Jillie's grade 2 science project on magnetism. During her research on magnets she discovered speakers and insisted on making one.

She did all the research herself. I (her dad) wound the first coil myself. Then we did some experiments to find something to turn into a speaker. We tried many speaker shaped things around the house. She is the one that had the CD case idea. A quick test with some tape and a couple magnets was a success.

The red coil in the video was wound by herself with a little help from me. It isn't easy to wind a coil without a proper form.

As you can see in the video she did the rest herself.

Yes she did solder the wires herself. I taught her to solder when she was 5. She needed to solder to build a robot we started together...but that's another video for another time.

The small circuit board has the music. It is from a musical toothbrush. The other circuit board is just a battery holder. We could have used any sound source but I wanted to use something that would fit inside the case. We sealed it up and she took it to school.

She is a bit congested form allergies in this video. That's why she sounds a bit funny.

    Wow girl, you've got some mad smarts. You're only seven, and already making your own speaker. I don't think I could've even done this project as a 7th or 8th grader. Very nicely done :).

    Yes it does :) Better than we thought it would. It is still at her school. The other kids are fascinated by it. When we get it back maybe we will make another video with different audio sources and more detailed pictures. Thanks for the comment.
