This is in the wake of the idea I had last week, about using the backpressure of a speaker as a pumping system for a smoke unit...

It's one thing to test an idea on a bench; but making it work in a model is another ball game...

Nevertheless, I succeeded in mounting a small (but powerful) taigen speaker between the gearboxes of my H.L. Pershing; and couple it with the smoke chamber of a modified H.L. smoke unit.

Since the idea came to me while I was working on a modification to boost the audio output of my tank; I blended both smoke and sound together…

The audio modification is based on a 2 X 15 Watts Stereo Amplifier that I bought on E-Bay.

My original plan was to use only one channel to drive a taigen speaker mounted in the front of my tank.
I also connected my two batteries ( 5000 Mah NiMH) in serial; to get around 15 Volts to the Amp.

For the new modification, I’m using the 2 channels to power 2 speakers…
Each channel has it’s own volume control; so I can set the volume of the rear speaker to get the level of smoke that I desire; and use the front speaker as a master for the overall sound level…

Here’s a static video of the system…
