Abstract:

Graphene has extremely low mass density and high mechanical strength, and key qualities for efficient wide-frequency-response electrostatic audio speaker design. Low mass ensures good high frequency response, while high strength allows for relatively large free-standing diaphragms necessary for effective low frequency response. Here, we report on construction and testing of a miniaturized graphene-based electrostatic audio transducer. The speakerearphone is straightforward in design and operation and has excellent frequency response across the entire audio frequency range 20 Hz 20 kHz, with performance matching or surpassing commercially available audio earphones
