Printed paper speakers roll into a ring to offer surround sound

Scientists at Germany’s Chemnitz University of Technology have spent years developing compact and discreet speakers that are quite literally paper thin, and the latest breakthrough improves on this technology for a more immersive experience. The scientists have come up with a way to print continuous rolls of paper loudspeakers that can be fashioned into circular rings to offer surround sound, which they hope could serve as low-cost infotainment systems for interior spaces.
The research was carried out at the university’s Institute for Print and Media Technology and builds on a 2015 breakthroug
