PROBLEM TO BE SOLVED: To provide a diaphragm for a speaker having high sound quality that is excellent in response performance without reducing the output sound pressure level, and can reduce the peak dip on sound pressure frequency characteristics.SOLUTION: There is provided a cone-shaped diaphragm for a speaker, the diaphragm composed of resin material including a carbon fiber-reinforced liquid crystal polymer, cyclic olefin-based resin, and carbon nano-tube, and including a cone-shaped diaphragm main body having a shape symmetrical with respect to a predetermined central axis, and a sound quality adjustment member projecting from a part of the outer peripheral surface of the diaphragm main body. |
