Description

Six-channel speaker surround system

technical field

The utility model relates to the field of audio technology, in particular to a six-channel loudspeaker surround system.

Background technique

People only have two ears, but they can feel the sound in three-dimensional space. But a mono system can only convey the most important information in music, such as melody, timbre, beat, reverberation, etc., without a sense of space and surround. The two-channel system can only reproduce a limited front sound field, which is difficult to satisfy the reproduction of the original sound field and obtain a sense of presence, which often leads to the exaggeration of the hollow effect and the left and right channel effects. As people's requirements for hearing become higher and higher, the four-channel system came into being. The four-channel system stipulates four pronunciation points: front left, front right, back left, and back right. As far as the overall effect is concerned, the four-channel system can bring the listeners surround sound from multiple different directions, and can obtain the auditory experience of being in various environments, but these different environments are based on the playback of movies and TV. . If it is from the perspective of game lovers, it will not meet the requirements. Similar to the current "chicken eating" game, the sense of direction, space, gunshots, etc. need to be accurately positioned in terms of hearing.

5.1 channels include six channels: front left channel, front right channel, rear left channel, rear right channel, center channel and subwoofer channel. 5.1 channels can highlight the surround sound of home theater more The effect has been widely used in various traditional theaters and home theaters. However, the 5.1-channel audio system used in theaters usually includes multiple speakers, and each speaker must be placed in a corresponding position, which is very inconvenient to use and is not suitable for game lovers.
