Abstract

The embodiment of the invention relates to the field of audio signal processing, and discloses a tone quality adjustment method, which comprises the following steps: acquiring an audio signal to be adjusted; obtaining a resonant frequency and a frequency response curve of an exciter; forming a recursive filter, and determining filter parameters of the recursive filter according to the frequency response curve; inputting the audio signal to be adjusted into the recursive filter within a preset range of the resonant frequency to obtain an equalization signal; performing preset sound effect processing on the equalization signal to obtain a to-be-excited signal, the preset sound effect processing at least comprising inputting the equalization signal into the non-recursive filter; and inputtingthe signal to be excited into the exciter to output an audio signal. The invention also provides a tone quality adjusting device. The tone quality adjusting method and device provided by the invention can enhance the damping effect and improve the screen sounding tone quality.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio signal processing, and in particular, to a sound quality adjustment method and device. Background technique [0002] The screen sound smartphone is a smartphone that perfectly integrates the earpiece function and the IPS high-definition screen. There is no need to set the earpiece sound hole on the front of the phone. When the piezoelectric driver is powered on, the touch screen of the phone will vibrate, and then push the air to produce sound. This design method is not only convenient for users to answer, but also makes the call effect clearer. Through the revolutionary cancellation of the earpiece structure on the smart phone, the full mirror design of the phone is realized, and the front of the phone can be waterproof and dustproof. Screen sound smartphones need to apply screen sound technology. Screen sound technology refers to the technology of placing an exciter behind the screen, ...
