Interesting results. The piezo makes sense as the receiver and not to knock the design using the speaker on the middle is a clever way of creating a sender.
If I was working on this I would have to find a way of reducing the input power to a smaller unit.
Wasn't there a speaker system invented that you could attach to objects like tables that turned the table into a speaker?

Anyway, it's a great design concept with great results.

They're called tactile transducers. You can find them easily at places like parts express. I've experimented with them some in the past. I've done something similar to the above, but a 'small' cymbal like this has a very pronounced high resonant frequency that gets old real quick in a mix. I've had better results with wooden sound boards and more esoteric shapes that resonate more neutrally at multiple frequencies.

For Plate Reverbs normaly "size matters"... I one build a plate like shown above, one will get extrem resonance tones, wich could be interesting but also anoying...

I have build a Plate Reverb a few years ago, its not to big, but works fine - not complete "neutral" but ok. Its non magnetic stainless steel (0.5 as far as I remember)  watch the asymetrical mountings. With the one speaker coil input and the two piezos,  I get a "stereo" output reverb from mono.
