Problems solved by technology

For existing electronic equipment, take TV as an example, considering the manufacturing cost of TV, generally there are only two built-in speakers in TV, that is, two pairs of sound channels on the left and right, and both speakers are located on the screen of the TV. In the X-axis direction of the TV, when the TV is playing a movie, the sound can only be played from the two speakers, and the user will feel that the sound is continuously played from the X-axis direction, and the three-dimensional effect is not obvious, which greatly reduces the user's perception Shadow perception
In order to solve the above-mentioned problems in the prior art, the method of connecting the TV to an external audio system is adopted, and the audio system is placed around the user to improve the stereoscopic effect of the sound, but the above-mentioned method has certain limitations:
[0004] First, the way of connecting external speakers will greatly increase the cost of users. Users must purchase additional speakers to improve the three-dimensional effect of the sound. For users with relatively poor economic conditions, the way of connecting external speakers is not advisable;
[0005] Second, the way of external audio will also take up a lot of space in the family house, and users have to reserve more space to install audio, which is also not advisable for users with limited economic conditions.

Embodiment 1

[0054] Before the description of embodiment one, in embodiment one:

[0055] The position coordinate target value set includes nine position coordinate target values:

[0056] The preset conversion function relationship is specifically:

[0057]

[0058]

[0059]

[0060]

[0061]

[0062]

[0063]

[0064]

[0065]

[0066] Among them, X L (n) is the coordinate source value of the left channel position, X R (n) is the right channel position coordinate source value, N is the average value of the sum of the left channel position coordinate source value and the right channel position coordinate source value, k is the volume value, CM(n), LM(n), RM(n), LH(n), LL(n), CH(n), CL(n), RH(n), RL(n) are nine position coordinate target values;

[0067] Correspondingly, see again figure 2 , the sound group 200 includes nine speakers 210, and the nine speakers 210 are all arranged in the 2D screen of the object to be tested, and the nine speakers 210 are arr...

Abstract

The invention discloses a Y-axis audio regeneration method and a Y-axis audio regeneration system. A sound box group comprises nine loudspeakers, at least two loudspeakers are located in the X-axis direction of the two-dimensional plane of the to-be-measured target, and at least one loudspeaker is located in the Y-axis direction of the two-dimensional plane of the to-be-measured target; the central processing module acquires the dual-track position coordinate source value and the volume value, disassembles the dual-track position coordinate source value into a position coordinate target valueset according to a preset conversion function relationship, and finally outputs the position coordinate target value set through corresponding loudspeakers; because the loudspeakers are arranged in the X-axis direction and the Y-axis direction, and the position coordinate target value set comprises nine position coordinate target values, the sound played by the audio image synchronization system is more stereoscopic, and the auditory feeling of the user is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of sound processing, in particular to a Y-axis audio reproduction method and a Y-axis audio reproduction system. Background technique [0002] With the continuous development of technology, people have transitioned from the silent film era to the sound film era. The emergence of sound films allows people to go to the cinema to watch films in their spare time to enrich their lives. But in the early days, only a small number of people could enjoy it due to the high ticket price of the movie theater. Subsequently, with the rise of electronic devices, such as televisions, mobile phones, tablet computers, etc., electronic devices have entered thousands of households, and people can use electronic devices to watch the movies they want to watch at home. [0003] However, unlike watching in theaters, due to the limitations of the structure of the electronic device itself, when the user uses the electronic device to...
