Problems solved by technology
[0007] The speaker arrangement in the prototype system of 3D audio playback of 22.2-channel technology in the prior art does not exactly match the existing standard 5.1 system, 7.1 system, 8.1 system and 10.1 system
If there are no speakers at M+110 and M-110 in the prototype system, they can only be replaced by two sets of speakers M+135 and M-135, which will cause changes in the position of the rear sound object and different reverberation bands. Different sound field perception, reducing the sound quality effect
