Chalmers University to develop graphene-based loudspeaker membranes
Chalmers University in Sweden has launched a project, which received Vinnova funding, to design a graphene-based speaker membrane that would be stiff and capable of efficiently dissipating the exceeding heat of the speaker.
A cellulose-graphene composite will be designed, capitalizing on the intrinsic properties of the materials. To demonstrate this, Chalmers plans to use a commercial paper loudspeaker membrane modified with the composite. This way it will be possible to modify any size of paper cones from small 20 mm (tweeters) up to 460 mm (18” woofers) with the same technology, while offering the possibility of decreasing the distortion.
