Graphene oxide based acoustic transducer methods and devices

Abstract

Materials used in acoustic transducer membranes need very specific qualities that in any real system require many tradeoffs to be made. Graphene and graphene related materials are a newly discovered class of materials with some exceptional properties that offer the potential for significant contributions to the performance of many acoustical transduction systems. Accordingly the inventors have established graphene oxide based transducers as the basis of ribbon microphones and diaphragm loudspeakers using low cost manufacturing and processing techniques.
