abstract = "Graphene is an excellent two-dimensional (2D) material and can be deployed as sound emitters based on electrical thermoacoustic effect (ETA). Traditional graphene-based ETA emitter renders ineffective audio quality in low frequency range due to its small output magnitude and large total harmonic distortion. Here we propose a packaging method that boosts its low frequency output magnitude from 58 dB to 70 dB at 5 kHz as well as a fully digital operation that eliminates its major source of distortion down to 2.29\%. Besides, a Bluetooth module is applied to extend the application of graphene in wireless communication field. Our work shows the great potential of using wireless graphene earphone for practical applications.",
