By the use of laser modal analysis and FEM computer simulation, the cause of high-frequency resonance peaks of a cone diaphragm loudspeaker has been studied and removed. The design of this peakless diaphragm incorporates an IIR surround material to damp the first resonance mode, and an arrangement of low-density material on the cone diaphragm surface to make the second mode nonuniform.
