Sound Exciter
Description
This is a mini bass shaker, and can act as an sound exciter, this mean that when in contact with a surface it produces sound. High quality speakers can be produced using this idea if the right surface is chosen. Bellow there is a video of it working: https://youtu.be/JqNlEx1MCE4 The idea of this device is very simple, there are two coils, that I got from a step motor, that are activated by an amplifier connected to a sound port. For this test I was using 12 v with 1 A.
