Here's inventor David Schwartz's latest test of his new laser-based microphone design.
We reworked Proto 1 to make this unit. It's half the size of P1, uses a $30 trace line laser, a larger aperture nozzle, and a single fan. Sounds better, but still a long way from being a commercial product.
Schwartz has a patent on his laser mic design - but the current implementation is bulky and sounds muffled.
Whether or not Schwartz is able to translate his patent into a useful microphone, though, it's interesting to be able to look over his shoulder as he develops and iterates his design.
