1. A method for improving sound quality of a speaker, the method comprising:
performing, based on a direct current resistance of the speaker, interpolation on a first nonlinear parameter of the speaker to obtain a second nonlinear parameter of the speaker, wherein the first nonlinear parameter is preconfigured in the speaker;
performing signal compensation on a first input signal of the speaker based on the t-hifd second nonlinear parameter to obtain a compensated first input signal; and
performing filtering on the compensated first input signal to obtain an output signal of the speaker.
