Abstract
The method can include depositing a graphene oxide containing material from solution to form a laminar nano-structure of graphene oxide paper, and assembling at least a portion of the graphene oxide paper as a diaphragm of the acoustic transducer. The acoustic transducer can be a magnetic induction based microphone, a diaphragm loudspeaker, or a magnetic induction based loudspeaker, for instance.
