Passive Cell Phone Speaker


For this weeks project I decided to do a scrap bin project, I did a bunch of tinkering with creating various sound boxes, to see how it would reproduce and enhance sound from the tiny speaker in my Galaxy 5 cell phone. You can adapt the basic design to work with any other cell phone, I just happen to have a Galaxy 5.

The basic idea is to create a chamber for the sound to expand into and then some sort of bell/funnel to allow the sound to escape and promote expansion.

The build is documented here in my YouTube build video.
