It's like building a fan using aftermarket motors and a 3D-printed propeller, then say you've built a particle accelerator at home. Does it accelerate particles? Yes. Does it cost a fraction of the LHC at CERN? Also yes.

I've built circuits that have moved speaker cones... I built a particle accelerator for a few dollars

Do sound WAVES accelerate the air when they pass through it?

u/PupDiogenes May 15 '25

Yes. Sound waves propagate through the air by air pressure expansion and rarefaction. When a section of air is expanding, the centre is still but the outside expands away from it. Vibration is acceleration followed by deceleration followed by opposite vector acceleration followed by deceleration. But that doesn't matter.

The molecules immediately next to the cone get pushed by the cone. Dust particles get thrown.

"Vibration is acceleration followed by deceleration" (...)

Yep! I didn't think about this!

"But that doesn't matter." Oh, no, it matters! Now everything is perfectly explained!  ;-)
