How does it work? Well, instead of the coil and magnet system that's been used for over a century, MEMS drivers rely on a voltage-driven monolithic piezo drive that convert signals into sound. This design sees a silicon diaphragm used for the speaker, with the piezo layer distributed evenly under the diaphragm surface.

I'm no engineer, but that sounds different than normal speakers to me.

But it doesn't imply solid state. There are ways to move air without moving parts, but this device clearly has moving parts.
