The piezo rod element in an electronic spark lighter generates a decent blue spark, they have an impact spring like the automatic centre punches. They make very sensitive vibration transducers if you can figure out how to mount them.

My TL431 electret booster works extremely well with such a transducer. Elektor paid me for the copyright, so I can't post the schematic - but it obviously has escaped into the wild, because other people have posted it here several times.
