Intriguing, it sounds like this uses the piezoelectric effect, but could you DIY a surround sound electrostatic speaker using the same kind of form factor?

- cesaref 6y agoWell, not electrostatic, as that requires static charge, stators, and rather high voltages (10s of kv) which is unlikely to happen in a piece of paper. The basic approach reminds me of the flat panel speakers that came out of QinetiQ I think in the early 2000s, that a large surface vibrating somewhat chaotically doesn't suffer from the directional phasing you see with pistonic movement of the surface. I'd definitely like to hear how this setup sounds. I guess another interesting fact is that many traditional speaker cones are made from paper, it's amazing stuff!
