Default fullrange piezos

Hello all!

I need flat piezo elements (diameter below 1") that can be used fullrange. Neither sound quality nor volume needs to be high, just fullrange noise at headphone levels. The piezos I found at a wellknown supplier for electronic parts have resonance frequencies around 5kHz.
Can anybody help me?
Some time ago I read about piezo elements at the NXT website, but couldn`t find them again.
Does anybody know what has happened to them? And were they fullrange?

Greets, Oliver

I have seen something like that this year at the "Hannover Messe"
can't remember it exactly, but must have been shown by a Fraunhofer institute.
Regards
