When it comes to high-fidelity sound, what could be better at reproducing a human's voice than an actual human? Bypassing the vocal chords, Nic Wallenburg's Human Speaker collar uses the wearer's mouth and lips to control and amplify sounds, essentially turning the wearer into a speaker.
It's just too bad that each collar can only produce up to two notes at a time — the dream of using these collars as high-fidelity human speakers goes out the window. But if you can wrangle enough folks wearing these collars, you can put on a performance that rivals even Queen's Bohemian Rhapsody. [Nic Wallenberg via PSFK]
