The invention provides a tone quality self-adaptive adjustment method which comprises the following steps that S1, an audio system collects background noise of the environment where the audio system is located; S2, the processing module performs noise analysis on the background noise and calculates the total output sound pressure level of the background noise according to an analysis result; s3, the processing module calculates the gain of each frequency band needing to be adjusted by the power amplification module according to the analysis result; S4, the processing module calculates the total output sound pressure level needing to be generated at the target position according to the distance between the target position and the loudspeaker so as to meet the preset signal-to-noise ratio; S5, the power amplification module adaptively adjusts the gain of each frequency band according to the total output sound pressure level, and plays the gain according to a preset playing mode through aloudspeaker. The invention further provides the audio system, display equipment and a computer readable storage medium. Compared with the prior art, the audio output by adopting the technical schemeof the invention is high in signal-to-noise ratio and good in tone quality.
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...
