Claim 7:
8. A sound quality improvement apparatus, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and configured to store programming instructions for execution by the at least one processor to cause the sound quality improvement apparatus to:
perform, based on a direct current resistance of a 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;
perform signal compensation on a first input signal of the speaker based on the second nonlinear parameter to obtain a compensated first input signal; and
perform filtering on the compensated first input signal to obtain an output signal of the speaker.
