The end for conventional loudspeakers?

Then there is the prior art.
Bones Hi - Fi: Digital Loudspeakers: Viable Hi-Fi Technology?
The famous digital speaker April fool article, actually published by Stan Curtis back in 1998, which describes the basic technology used by these Australians closely

The article was written in 1980, he come clean about it in 1998.

Just because it was written in jest, does not invalidate the ideas he published from being prior art, limiting just what these Aussies can claim in their patents

Sorry, they are not Aussies, but people from America and Israel, they are using Australia as some sort of proxy.

I can see how this might effectively bypass Fs, Q, and Le.
But I don't see anything that defeats the need for xmax,
nor anything that transforms pressure into air movement
fitting the size package they target.

You are energizing a big coil at high frequency to move
even one unlatched pixel. And hopefully no eddy currents
wasted in anything else nearby. I'm puzzled how such a
scheme could hope to run from a battery....
