Embodiment 1

[0036] The embodiment of the present invention provides a multi-channel playback method, which can provide users with 3D multi-channel playback effects in different spaces. , through the test data to obtain the number of spatial speakers, the relative position between the speakers, and the location of the user; Each speaker can be set in order to provide users with 3D multi-channel playback effect.

[0037] Specific as figure 1 As shown, the method includes:

[0038] Step 101, determine the number of speakers;

[0039] Wherein, the speakers in the space are interconnected through a wireless or wired network, and the three-dimensional multi-channel sound playback device can determine the number of wireless speakers through the hardware device management module through software. In addition, the device for playing three-dimensional multi-channel sound effects can also output a test sound source to each wireless speaker through the driver program at the bottom of the software....

Embodiment 2

[0085] This embodiment describes a multi-channel playback method, which belongs to another preferred solution of the same inventive concept as the method provided in the first embodiment. Channel application, this scheme uses two speakers, and assumes that the two speakers are placed in the front left and right of the user. After the 3D multi-channel sound effect playback device is identified and calibrated, the listener can achieve the best two. listening effect of the channel.

[0086] Assuming that a sound field environment includes two speakers and an output device (the output device can be a mobile phone, but is not limited to a mobile phone, for ease of understanding, the output device will be described as a mobile phone), the two speakers and the output device are located in same network. like Figure 11 As shown, the method specifically includes:

[0087] Step 201, after the mobile phone starts the 3D multi-channel function (specifically, it can be an application pr...

Embodiment 3

[0095] This embodiment describes a multi-channel playback method, which belongs to another preferred solution of the same inventive concept as the method provided in the first embodiment. Channel application, this scheme uses two speakers, and assumes that the two speakers are placed in the front left and right of the user. After the 3D multi-channel sound effect playback device is identified and calibrated, the listener can achieve the best two. listening effect of the channel.

[0096] like Figure 12 As shown, the specific operations of the method include steps 301 to 306 , wherein, except that step 303 is different from step 203 , other steps are identical to steps 201 to 202 , and steps 204 to 206 . For the same steps, this part will not be repeated, and for different steps 303, it specifically includes:

[0097] Step 303, the mobile phone obtains the relative position between the two speakers input by the user.

[0098] The embodiment of the present invention provides...

Abstract

The embodiment of the invention discloses a multichannel playing method and a system. The method comprises steps: the number of sound boxes is determined; sensing signals from other sound boxes acquired by a microphone of each sound box are acquired, and according to the sensing signals from other sound boxes acquired by the microphone of each sound box, the relative position of each sound box is determined; image signals acquired by a camera of each sound box are acquired, and according to the image signals acquired by the camera of each sound box, the relative position between the user and each sound box is determined; and according to the determined number of the sound boxes, the relative position of each sound box and the relative position between the user and each sound box, each sound box is configured, and playing of 3D multichannel sound effects can be realized. according to the technical scheme provided by the embodiment of the invention, the problem that multiple connected sound boxes can not be integrated in the prior art, and thus 3D multichannel playing effects can not be provided can be solved.

Description

technical field [0001] The invention relates to the technical field of audio systems, in particular to a multi-channel playback method and system. Background technique [0002] The quality of the playback effect of the audio system has a very obvious experience for the user. The audio system with a good playback effect gives users a very pleasant enjoyment, while the audio system with a poor playback effect directly affects the expression of audio resources. What science and technology workers have been pursuing is to allow users to feel immersive while hearing the sound. Especially in a specific space, when there are multiple speakers, how to make the multiple speakers cooperate intelligently and provide users with high-quality playback effects is an important problem that technicians need to solve. [0003] However, in the prior art, each speaker can play its own function. Even if multiple speakers are connected to the network for simultaneous playback, the three-dimensio...
