Abstract: The present application provides a method of audio signal processing. The method comprises obtaining a voice coil direct current resistance of a speaker. The method further comprises obtaining an audio input signal to be input into the speaker. The method further comprises determining an audio input power based on the voice coil direct current resistance and the audio input signal. The method further comprises obtaining a thermal model of the speaker, and determining a transient power threshold based on the audio input power and the thermal model. The method further comprises determining a power constraint gain based on the audio input power and the transient power threshold. The method further comprises obtaining a voice coil temperature of the speaker. The method further comprises determining a temperature constraint gain based on the voice coil temperature and an upper operating temperature limit of the speaker. The method further comprises adjusting the audio input signal based on the power constraint gain and the temperature constraint gain, to obtain a target signal.

Abstract: A method for improving sound quality of a speaker includes: performing frequency division on an input signal of the speaker to obtain a first low-frequency input signal and a first high-frequency input signal, where the input signal is 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; determining an output signal of the speaker based on the second low-frequency input signal and the first high-frequency input signal, where a startup voltage of the second low-frequency input signal is higher than a startup voltage of the first low-frequency input signal, and loudness of the second low-frequency input signal is greater than loudness of the first low-frequency input signal.
