Abstract
The present disclosure relates to a balanced armature receiver diaphragm including a paddle (202) flexibly coupled to a frame (204) and spaced apart therefrom by a gap (206). The paddle comprises a material having a specific modulus kg/m3) in at least one direction and density selected to increase stiffness and reduce mass. In one implementation, at least the paddle includes a carbon fiber material. The resulting paddle has improved acoustic performance including improved frequency response and less resonance in the audio band, among other benefits.
