On a serious note though, rotary woofers are legit but:
THIS IDEA WON'T WORK
At least... not how you are going about it thus far.
The duration is too small!!!
in order to generate on-the-fly DBox vibs or AC blower instructions or smoke/mist/smellovision would require pre-delayed video/audio or pre-encoded movie meta-data (which is how DBox works... i.e. ain't no real-time on-the-fly stuff)
You could "fake it" convincingly...
The effects coming from the fans would be a delayed-action.
In that case, you could just use normal DC fans.
This would STILL require you to learn a programming language and interfacing with a relay controller system (to activate the fans automatically by command), similar to what I built a few years ago for power control automation for the rack of AV gear.
You'd have to code your own DSP software algorithms though. Which is a highly-advanced skillset. Basically you need to calculate the frequency with an FFT (frequency /amplitude gating), and then also the duration (attack/release gating), and use that as the basis of how you would activate the fans.
The good news is that you could reuse this logic for a DBox-like effect using chair hydraulics.
All of this sounds highly-obtuse and esoteric, even for me...
