Crystalline Nanocellulose-Reinforced Paper for Speaker Design

NE_2014_13 Crystalline Nanocellulose (CNC) is a novel green material with mechanical properties rivaling those of Kevlar. Cellulose paper has long been used in the production of loudspeaker cones as it yields desirable acoustic properties. By implementing CNC into a paper composite, we hope to achieve superior mechanical properties without compromising audio quality, allowing for thinner, lighter speaker cones and a significant reduction in speaker driver cost.
