  > Piezoelectricity Ceramic capacitors can have similar issues: apply voltage, part warps a tiny bit. @ the right frequencies some (mechanical) resonance effects might come into play. Yay! But I have a hard time imagining this to be a real-world problem. Edit: "microphony" or "microphonics" https://en.wikipedia.org/wiki/Microphonics https://en.wikipedia.org/wiki/Microphonics Just an idea: coil whine might be reversible too. Vibrate coil, get some (noise in) inductor current. Oh yeah: don't yell too loud at your (spinning) harddrives.
