Embodiment 1

[0108] Such as figure 1 As shown, the method for reconstructing stereo in Embodiment 1 of the present invention is applied to speakers, and the method includes:

[0109] Step 11: Determine the location of the current listener;

[0110] Step 12: Obtain the predetermined optimal relative position of the speaker, the optimal relative position of the speaker is determined based on the pickup position of the collected stereo sound and determined according to a predetermined algorithm, and is used to indicate the distance between the speaker itself, other speakers and simulated listeners Relative positional relationship;

[0111] Step 13: According to the position of the current listener and the best relative position of the speakers, adjust the position of the speakers themselves to reconstruct the stereo sound.

[0112] Wherein, the predetermined algorithm is an algorithm corresponding to the flow algorithm of the information sent by the speaker using the pickup.

[0113] The s...

Embodiment 2

[0123] The method for reconstructing stereo sound provided by Embodiment 2 of the present invention is specifically as follows:

[0124] When the speaker is rebuilding the stereo (before the stereo synthesis), the position adjustment is carried out in the following way:

[0125] 1. The audience sends instructions to the speaker, which may be voice or infrared light signals, and the speaker locates the audience through the phase difference of the sound or other methods.

[0126] 2. Adjust the speaker to the best position according to the position of the audience and the best relative position of the speaker. The best position must be the position of the pickup in the simulation state, which is calculated by simulation;

[0127] If the speaker is in the best position at the beginning, there is no need to move it, and the stereo can be directly reconstructed;

[0128] If the speaker is not in the best position at the beginning, it will automatically walk, and there is no restric...

Embodiment 3

[0135] Such as figure 2 As shown, the speaker in Embodiment 3 of the present invention includes:

[0136] The first determination module 21 is configured to determine the position of the current audience;

[0137] The first acquiring module 22 is used to acquire the predetermined best relative position of the sound box, the best relative position of the sound box is determined based on the pickup position of the collected stereo sound and determined according to a predetermined algorithm, and is used to indicate the sound box itself and other sound boxes and Simulate the relative positional relationship between listeners;

[0138] The first processing module 23 is configured to adjust the position of the sound box itself according to the position of the current listener and the best relative position of the sound box to reconstruct the stereo sound.

[0139] Wherein, the predetermined algorithm is an algorithm corresponding to the flow algorithm of the information sent by t...

Abstract

The invention provides a method for rebuilding stereo, a loudspeaker box, a position information processing method, and a pickup. The method for rebuilding stereo comprises the steps of determining a position of a current audience; acquiring a predetermined optimal relative position of the loudspeaker box, wherein the predetermined optimal relative position of the loudspeaker box is determined based on a position of the pickup for collecting the stereo and according to a predetermined algorithm, and used for indicating relative position relations between the loudspeaker and the other loudspeakers and simulative audiences; and adjusting the own position of the loudspeaker according to the position of the current audience and the optimal relative position of the loudspeaker box to rebuild the stereo. According to the scheme of the method provided by the invention, the own position of the loudspeaker is adjusted according to the position of the current audience and the optimal relative position of the loudspeaker box, so that the position of the loudspeaker box relative to the current audience and the other loudspeakers accords with the predetermined optimal relative position of the loudspeaker box to rebuild the stereo, and thus the best sound field reproduction can be achieved, a user can hear the best stereo effect, and high quality requirements of the user can be met.

Description

technical field [0001] The invention relates to the technical field of data services, in particular to a method for reconstructing stereo sound, a sound box, a position information processing method and a sound pickup. Background technique [0002] The so-called surround sound, usually compared with two-channel stereo, refers to a playback method in which the sound seems to surround the listener. The replay sound field generated by this method, in addition to retaining the sense of direction of the original signal, is also accompanied by the sound effect of creating a sense of surround and expansion (the sound diffuses away from the listener or has a feeling of reverberation). When listening to surround sound, the listener can distinguish the sound from the front, rear, left, and right, that is, the surround sound can expand the spatial sound source from the line to the entire horizontal plane and even the vertical plane, so it can realistically reproduce the spatial reverbe...
