Speaker printed on paper

[ShearMe]

Not exactly the best sounding speaker, but none-the-less, a speaker printed on paper: http://www.wired.com/design/2013/12/a-tiny-speaker-made-out-of-paper/

there was a 3d printed plastic speaker done a while back as well. they had to change the heads a couple times to switch between plastic and metal layers.

Sweet concept.. Combine this with the conductive ink and soon you'll have books that can read by itselves when flipping page by page.  What sort of paper are they using? I hope it is recycleable.
