Wolfgang,
I admire your enthousiasm. I know (almost) nothing about electronic devices. Do I understand correctly that the vacuum pump in the case on a turn table is the source of the frequency? I am afraid that its waight is much to little. Maybe a iron cylinder of several nundreds of kilo's is needed. And a heavy lead block attached to the piezo crystal. I wonder very much how sensitive piezo's are. Can they perceive forces as small as a micro gram (or even smaller)? I am very curious to your results.
