A diaphragm is a diaphragm...wiring a speaker up backwards creates a (piss poor) microphone, just as wiring a microphone up backwards creates a (even more piss poor than the other way around) speaker.
Fact:
Yes, shining a laser at something like a window, and measuring its reflected energy, creates a "laser microphone"... This is literally 70's technology...
At play in what, exactly? Are you still stuck on trying to figure out how they are using lasers to make people hear things...? Because that's not how they do it... Modulating an auditory signal onto an ultrasonic carrier wave is the most basic way to pull off Voice-to-Skull, and has been since they figured it out more than a decade before I was born.....

We are far, FAR beyond that now....
But... Can you induce vibrations with a laser? Or only measure them?
As far as I’m aware, you could only induce vibrations on something very small, such as a hair or piece of paper.
Just happened to read something where "light waves" have no mass, but do have momentum.... Perhaps that is the mechanism at play here?
