Document Type and Number:
WIPO Patent Application WO/2021/052110
Kind Code:
A1
Abstract:
The embodiments in the present application relate to the technical field of media, and provided therein are a method and device for improving the sound quality of a speaker, which can effectively improve the sound quality of a speaker. The method comprises: according to the direct current resistance of a speaker, interpolating a second non-linear parameter of the speaker to obtain a third non-linear parameter of the speaker, the second non-linear parameter being a non-linear parameter that is pre-configured in the speaker; performing signal compensation on a first input signal of the speaker by using the third non-linear parameter so as to obtain a compensated first input signal; and filtering the compensated first input signal to obtain an output signal of the speaker.
