Title:
METHOD AND APPARATUS FOR IMPROVING SOUND QUALITY OF SPEAKER
Document Type and Number:
WIPO Patent Application WO/2023/274180
Kind Code:
A1
Abstract:
Embodiments of the present application provide a method and apparatus for improving sound quality of a speaker, relating to the technical field of media, and capable of improving low-frequency sound effects of the speaker and improving sound quality of the speaker. The method comprises: performing frequency division on an input signal of a speaker to acquire a first low frequency input signal and a first high frequency input signal, the input signal being a time domain signal; performing transient detection on the first low frequency input signal to determine whether the first low frequency input signal is a transient signal; if the first low frequency input signal is a transient signal, performing signal envelope modulation on the first low frequency input signal to obtain a second low frequency input signal; and determining an output signal of the speaker on the basis of the second low frequency input signal and the first high frequency input signal. A starting voltage of the second low frequency input signal is greater than a starting voltage of the first low frequency input signal, and a loudness of the second low frequency input signal is greater than a loudness of the first low frequency input signal.
