Interesting Speaker Idea Answered
Well, this is a totally random idea I had about how to see sound. I would like someone to try to build this if they have the resources available. Pretty much it is an airtight box with an woofer driver in it. On the top is an clear acrylic tube with a light ball in it. There is a rod across the bottom of the tube to keep the ball from falling out. The idea is when the driver moves back, the ball is pushed up in the tube, and when the driver moves forward, the ball is sucked down.
