Engineers in England unveiled a new type of speaker in April. The design is as flat and thin as a sheet of paper. What's more, the engineers say, it has the ability to project sound across distances without a deterioration of quality or volume. Called the Flat Flexible Loudspeaker, the device was created at Warwick Audio Technologies, a company aligned with the University of Warwick. It is made up of a laminate of two conducting membranes, one continuous and the other comprising a fine mesh, separated by an insulating layer.
