Graphene loudspeaker


"Researchers in the US have made a graphene loudspeaker that has an excellent frequency response across the entire audio frequency range (20 Hz–20 kHz). While the speaker has no specific design, it is already as good as, or even better than, certain commercial speakers and earphones in terms of both frequency response and power consumption. "

This project will fabricate and study an electrostatic graphene based acoustic speaker.
