If you are interested for measuring and studying the vibration behavior of any audio component like a loudspeaker driver, a loudspeaker stand or a turntable you could use an accelerometer with a suitable amplifier.
You could find more information in my article in Audioxpress June 2011 which is posted also online here:

A reminder for those who missed the initial post.
I have available some PCBs and Front Panels for the construction of the Accelerometer amplifier.

I have available some PCBs and Front panels (as shown in the photo) for building the accelerometer preamplifier in a more professional look.
The cost for both the PCB and the engraved aluminum front panel is now 60 Euros.

I bought one of these after Jan Didden told me he had one. It really is a very nice instrument. It is not just to mount on a driver, I have not yet used it as such, but also very much to look for panel resonances.
Before George sold me one of his kits, I was almost completely in the dark when it came to panel resonances in loudspeakers I develop. The knock test only goes so far.
In short, highly recommendable.

I have available an assembled and calibrated unit of the accelerometer preamplifier with its ac adaptor (see photo).
