Technical Field

The invention relates to the technical field of Internet of things equipment, in particular to a sound quality optimization method for an intelligent sound with a screen, the intelligent sound and a playing system.

Background

With the development of various audio processing technologies and the updating of playing devices, the sound quality performance gradually becomes an important index for users to evaluate the quality of products. Similarly, the sound quality requirement of the user on the smart home device is higher and higher.

At present, most of intelligent sound equipment with a screen is subjected to constant-amplitude promotion in low, medium and high frequency bands under different volumes. In fact, however, the sound in the low frequency band needs to be played at a higher sound pressure than the medium and high frequencies to be more easily perceived by the human ear, so that the human ear does not have high perception of the low sound in the low-volume playing process, and even cannot completely perceive the low frequency.

Supposing that bass is excessively promoted at low volume, the periodic saturation topping phenomenon of bass is easy to occur at the time of equalizing volume, so that the audibility of bass is greatly reduced, and even the bass is broken; similar problems exist for medium and high frequencies as well.

Preferably, since the low and high frequencies are adjusted more frequently, the input mode that is easier to detect or operate can be selected to correspond to the adjustment of the low and high frequency portions.

In the embodiment of the present invention, the gain adjustment is further performed on the corresponding frequency band according to the number of times or the duration of the operation input, it should be noted that, it is not necessarily said that the greater the number of times of input or the greater the adjustment amplitude, specifically, in the embodiment of the present invention, the number of times or the duration of input is determined to be the number of segments of the audio, that is, the fine degree of the audio gain adjustment.

In the embodiment of the present invention, as a further preferred scheme, the amplitude of the adjusted gain is further amplified according to the current volume, the amplification range is 1 to 2 times, the corresponding volume is from 0 to the maximum, that is, when the volume is 0 or close to 0, the gain obtained by calculation is taken as the current gain; and when the volume is adjusted to be maximum, taking 2 times of the calculated gain as the current gain. The method can further balance the difference between the volume and the gain, so that the gain is adjusted along with the volume, and the problem that the low gain cannot be heard well due to the volume is solved.

if the input operation is gesture input, performing gain adjustment on low frequency;

if the input operation is voice input, performing gain adjustment on the intermediate frequency;

and if the input operation is remote control input, performing gain adjustment on the high frequency.

In the embodiment of the present invention, the correspondence between the input mode and the frequency band is an optional specific implementation mode, which can be matched according to the setting of the user; of course, more generally, an input mode corresponding to gain adjustment and differentiation of all frequency bands may be adopted, for gesture input, different gestures may be used to correspond to different frequency bands, for voice input, different specific keywords may be made to correspond to different frequency bands, and for remote control input, different keys may be made to correspond to different frequency bands.

In one embodiment, the gain adjustment is performed on the corresponding frequency band according to the number of the input operations, and specifically includes, for a low frequency band, the steps of:

wherein:in order to achieve the adjusted gain, the gain is adjusted,gain before adjustment;the number of frequency points with the frequency within the range of 5 Hz-50 Hz in the ith section and the jth section is shown;the gain corresponding to the j frequency point in the ith segment (or the (i + 1) th segment) is obtained.

In the embodiment of the invention, for the low-frequency part, the gain of the low-frequency band can be correspondingly increased through the formula, so that the low-frequency band can have higher hearing feeling under the same volume and is easier to be felt by human ears. In general, for gain adjustment in the low frequency band, the goal is to boost the gain. As a further implementation, the magnitude of the gain may also be combined with the current volume, with particular reference to the foregoing embodiments of the invention. In addition, the gain adjusting mode in the invention considers the problem of uniform adjusting amplitude between different segments, and the average value of the original gain between two adjacent segments of audio is used as the adjusting reference, so that each segment of audio after adjustment can provide gain, the difference of the gain between different segments is kept, and both gain adjustment and fidelity are considered.

In one embodiment, the gain adjustment is performed on the corresponding frequency band according to the number of the input operations, and specifically includes, for the intermediate frequency band, the steps of:

In the embodiment of the invention, for the intermediate frequency part, the gain of the intermediate frequency band can be correspondingly adjusted through the formula, so that the low frequency band can have more balanced hearing feeling under the same volume, and the low frequency band can be more easily accepted by human ears. Different from the gain adjustment of the low-frequency part, the gain adjustment of the intermediate-frequency part comprises two directions of increasing and decreasing, because human ears feel more sensitive to the intermediate-frequency part, the gain is higher, the value is increased through lowering to obtain more balanced hearing, and the gain is lower to improve; generally, for gain adjustment in the mid-band, equalization is targeted. As a further implementation, the magnitude of the gain may also be combined with the current volume, with particular reference to the foregoing embodiments of the invention. In addition, the gain adjusting mode in the invention considers the problem of uniform adjusting amplitude between different segments, and the average value of the original gain between two adjacent segments of audio is used as the adjusting reference, so that each segment of audio after adjustment can provide gain, the difference of the gain between different segments is kept, and both gain adjustment and fidelity are considered.

In the embodiment of the invention, for the high-frequency part, the gain of the high-frequency band can be correspondingly reduced through the formula, so that the high-frequency band can have softer hearing feeling under the same volume and can be more easily accepted by human ears. As a further implementation, the magnitude of the gain may also be combined with the current volume, with particular reference to the foregoing embodiments of the invention. In addition, the gain adjusting mode in the invention considers the problem of uniform adjusting amplitude between different segments, and the average value of the original gain between two adjacent segments of audio is used as the adjusting reference, so that each segment of audio after adjustment can provide gain, the difference of the gain between different segments is kept, and both gain adjustment and fidelity are considered.
