Why downloading more RAM when you can burn more SWAP

"When an AC voltage is applied to an X7R MLCC—such as the AC ripple on a switching power supply output—the capacitor physically vibrates at the ripple frequency. If that frequency falls in the audible range (20 Hz–20 kHz), the PCB acts as a speaker diaphragm and the capacitor generates acoustic noise"*
Does anyone tried to use that effect on purpose, to make a capacitor based solid state speaker? I'd be curious to see that in action! #electronics
