Abstract

The present invention provides a sound quality adaptive adjustment method, which includes the following steps: step S1, the audio system collects the background noise of the environment where it is located; step S2, the processing module performs noise analysis on the background noise, and calculates the background noise according to the analysis result. The total output sound pressure level; Step S3, the processing module calculates the gain size of each frequency band that the power amplifying module needs to adjust according to the analysis result; Step S4, the processing module calculates according to the distance between the target position and the loudspeaker. The overall output sound pressure level meets the preset signal-to-noise ratio; in step S5, the power amplification module adaptively adjusts the gain of each frequency band according to the overall output sound pressure level, and plays the sound through the speaker in a preset playback mode. The present invention also provides an audio system, a display device, and a computer-readable storage medium. Compared with the related art, the signal-to-noise ratio of the audio output using the technical solution of the present invention is high and the sound quality is good.

Description

【Technical field】 [0001] The present invention relates to the field of smart home, in particular to a sound quality adaptive adjustment method applied to a display device, an audio system, a display device and a computer-readable storage medium. 【Background technique】 [0002] With the advent of the smart home era, the number of display devices, especially smart TVs, continues to rise. Currently, smart TVs are extremely versatile, one of which is high-quality sound. [0003] However, in a noisy environment, what users expect is a high-volume sound; in this environment, if you blindly increase the overall volume output of the smart TV, on the one hand, it will cause the output upper limit of the entire audio system to be exceeded; On the one hand, it will exceed the tolerance of the speaker itself, especially the tolerance of the low frequency band, resulting in equipment damage. In a quiet environment, users expect high-fidelity sound. In this environment, the volume is n...
