A Canadian start-up is developing speakers with graphene-based diaphragms that it said could greatly enhance both battery life and sound fidelity. Based in Montreal, Ora Sound has created a proprietary nanocomposite formulation called GrapheneQ, consisting of over 95 per cent graphene combined with oxygen and other additives. According to the company, diaphragms made from GrapheneQ are compatible with existing speaker technology and deliver better frequency response and reduced distortion compared to other materials.
