Novel graphene loudspeaker

The invention discloses a novel graphene loudspeaker. The novel graphene loudspeaker comprises sound production graphene and a driving circuit thereof; the drive circuit comprises a filter module anda modulator module, and a boost circuit; the filter module, the modulator module, the boost circuit are electrically connected in sequence; the filter module comprises a filter A module and a filter Bmodule, the output end of the filter A module is connected with the input end of the filter B module, the output end of the filter B module is connected with the input end of the modulator module, and the output end of the booster circuit is connected with the input end of the graphene. The graphene sheet replaces the whole sound production device, so that the area of the loudspeaker is greatly reduced, the graphene sheet can be developed into flexible wearable electronic equipment, the sound pressure level of sound is improved, and the distortion condition of the loudspeaker is improved. 本发明公开一种新型石墨烯扬声器，包括发声的石墨烯及其驱动电
