An Experiment:-)
Inspired by Vaclav and Bernhard’s DIY laser projector with speakers and mirrors project at PIFcamp 2021.

Video taken in rush, showing the speakers playing the L and R channels of this sine-wave sample from youtube and a laser shining into one mirror, bouncing off the second and landing on a piece of paper. The mirrors are plastic and I’m holding the laser by hand. The speakers are also shifting because they are not stuck in place.
Video demo showing speakers playing this super low frequency music:
Made from:
two paper speakers (enameled wire, neodym magnet)
two pieces of mirror
one sterio amplifier >> https://www.adafruit.com/product/987
