Description

Novel sound system

Technical Field

The utility model relates to a stereo set technical field, concretely relates to new-type sound system.

Background

The sound system is a sound system which is formed by converting sound wave signals of original sound production field sounds into electric signals by a microphone, processing the electric signals by some electronic equipment according to certain requirements, and finally converting the electric signals into the sound wave signals by a loudspeaker for reproduction. The 5.1 sound track sound system is applied to various traditional cinemas and home cinemas, the 5.1 sound track is a sound system consisting of a central sound track, a front left sound track, a front right sound track, a rear left surround sound track, a rear right surround sound track and a 0.1 sound track bass sound track, a set of the system can be connected with 6 loudspeakers (horns) in total, and the 5.1 sound track realizes an immersive music playing mode by using 5 horns and 1 subwoofer. Because the sound is output in five directions of left (L), middle (C), right (R), left rear (LS) and right Rear (RS) in the 5.1 sound track system, people feel like approaching a concert hall. The five channels are independent, wherein the '0.1' channel is a specially designed subwoofer channel. Just because there are speakers all around, so will produce the sense of reality of being surrounded by the music.

In order to ensure the original taste and flavor of the 5.1 sound channel and highlight the effect of a 5.1 sound channel system, the position of each sound box has very strict requirements, the sound boxes cannot be randomly placed beside a computer, and the sound boxes cannot be placed according to a common method. The front sound box is arranged in a manner of being arranged in a straight line to face a listener, the left and the right of the front sound box are respectively provided with a sound box, and the middle sound box is arranged on a desktop in front of the display or on the top of the display. The heights of the front sound box and the middle sound box are as same as possible, and the front faces of the three sound boxes are on the same plane, or the front face of the middle sound box is slightly backward but parallel to the front face of the front sound box. The distance between the front left and right sound boxes is related to the position of a listener, and in a normal viewing position, the angle between the sound boxes and the listener is 45 degrees.

One disadvantage is highlighted by the requirement of the position arrangement, namely the arrangement of the middle sound box. It needs to be as high as possible as the left and right main loudspeakers and to be placed at the center line of the display, which will conflict with the display. If placed on the top of the display or on a desktop, it can interfere with field decoration, wiring, and overall aesthetics.
