hi all,
new here, first post.
i'm working on an art installation involving a mechanically rattled window and recorded/played-back sound, and thought it might be interesting and closer to the intent of the piece to have the rattling mechanism actually controlled by audio signal so the rattle and sound are directly in sync. i have already gotten the window to rattle with a medium sized vibration motor (DC motor with an eccentric weight on the shaft), so i know that part works.
i designed a simple mechanism using an electromagnetic coil (haven't built it yet, just a drawing), which would replace the DC motor, and my thought was that in theory i could wire this in place of, or in parallel or series with a subwoofer so long as i wound the coil in my "motor" to the correct impedance.
i know that on a very basic level a speaker and motor work on the same principal, and that there must be some way to make this work, but i strongly suspect i'm oversimplifying things and missing something crucial as i've only a cursory theoretical understanding of how all of this works. i've also hit a wall on what to research in order to answer these questions myself, or i wouldn't be asking here. i'm not really trained in anything electrical or electronic, all of my knowledge and experience has just come from simple hobby circuits, and a bit of work with electric guitars and amplifiers.
hope all of that is fairly clear– here's the diagram for the mechanism i'm imagining (the dark grey bit would be a weight of some sort–i haven't worked out how heavy it should be, or any other dimensions for that matter), which would be mounted to the side of this custom window frame that's intentionally been left a bit loose in the wall it's mounted to:
-thanks!
