Great documentation about piezo

A project log for Stupidly Cheap Electronic Piano

I will try to make an electronic piano that looks good, for the lower possible price.

I found this documentation about piezo speakers:

The most interesting part for this project is the one where they exaplin how to calculate dimension of a resonnant chamber. If paper resonnant chamber gives good results, I will modify the polyphonic algorithm so it can select the piezo with closer resonnant frequency for each played note.
