AB  - Using digital signal processing techniques is an effective and low-cost way to compensate for nonlinear distortion of loudspeakers induced by the motor and suspension. Research shows that the nonlinear viscoelasticity of the suspension is also an important factor that distorts the acoustic output, but it is ignored in existing compensator designs. Therefore, in this paper, a new compensator that considers the nonlinear viscoelasticity of the suspension is proposed to reduce the nonlinear distortion. Experimental results demonstrate that the proposed compensator can significantly reduce the total harmonic distortion and intermodulation distortion in sound pressure while negligibly affecting the output sound pressure level.
