Using a Stronger Magnet

What difference would a stronger magnet make? Let's find out...

The strength of your magnet plays a huge part on the strength of the sound. I made another speaker using a Neodymium magnet. These are among the worlds strongest magnets.

The voice coil is made the same way, wrapping paper and wire around the magnet, then removing the voice coil shell and cutting it to size.
I used scrap wire I found on an old sump pump motor for this one.
   

This time, instead of using a foam bowl for the speaker basket, I just glued the magnet to another paper plate for a base, and made some accordion style supports to hold the coil over the magnet.
When the leads were connected and the music turned up, I was amazed at the results! It was rocking out!

Pouring water into the plate shows just how powerful the vibrations are with the stronger magnetic field. It also makes quite a mess.
