Sound then streams out from printed speakers, which are made from more layers of conductive inks that sit over an empty cavity to form a diaphragm. Mikael Gulliksson, who led the research project, told the BBC News website: “When you approach the billboard and put your hand on a postcard that shows a picture of a beach, you can hear a very brief description of that beach.”
