Abstract
A method includes: performing interpolation on a second nonlinear parameter of a speaker based on direct current resistance of the speaker to obtain a third nonlinear parameter of the speaker, where the second nonlinear parameter is a nonlinear parameter preconfigured in the speaker; performing signal compensation on a first input signal of the speaker based on the third 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.
