You talked way to fast and was impossible to understand through most of your demonstration. People from other regions should know other people weren't raised understanding different accents. I hope you stop and think and make yourself clear in the future.

I made this project. It was really good. Though when I connected it to a laptop by an audio jack it didn't work. What are the possible reasons for that.

ok, so how does this work? driving an audio signal into the magnet coil causes an oscillating magnetic field around the coil, correct? i'm guessing there's some kind of movement induced by that in the magnets. but, the batteries are stuck to the metal base, and therefore cannot move, right?

This is a simple speaker and works similar to any other, it is the coil that moves. There are no batteries in this design, they are a stack of magnets.

oops, i meant magnets, not batteries. Ok, so the MAGNETS are not moving, only the voice coil. So the coil (and the paper tube it's attached to) moves due to its magnetic relationship to the magnets. That in turn causes air to oscillate within the tube, kinda like a piston? That vibrating air in turn causes the plastic lid to vibrate. Right? thx
