It's made from a ceramic and polymer composite film, and that composite nature is why the film has minimal sound distortion no matter how the speaker might be folded or bent. And just to show one extreme example of how it might be folded, FujiFilm made the fan at right from the film. It's not a practical product yet, but it does offer decent sound.
Even if this never shows up in mobile devices, it still has great market potential. This film would make a great alternative to the existing tiny mobile speakers on the market now. It's both lighter and larger, and yet can simply be tossed into a bag when not in use.
I'd really like to see this speaker film be adapted for laptops. Most of the ones I've used have only marginal sound from tiny speakers. But if this film were mounted behind the screen, that could change. It would probably need to slide out of the case for best effect, but I think that's a fair trade off.
