[sdiy] OT: audio actuator

[Toby Paddock]

Has anyone tried these? I just ordered a couple.

They look like a small cheap "personal size" version 
of the home theatre under-the-floor-sub-bass-shaker 
things. I picture them being a voice coil hard mounted 
to the case and a soft mounted heavy magnet structure. 
If the voice coil is really tied well to the case, 
maybe the frequency response would go up 
above the bass range?

I was thinking of maybe trying a poor man's very-lo-fi 
plate reverb. Or maybe a really nasty feedback loop thing.
Or clamp it to the "small end" of a guitar for feedback?
