Sound box and sound diffusion system

Abstract

The invention relates to a sound box and a sound diffusion system. The sound box comprises a box body, angle diffusion panels and a front panel are arranged in the box body; the angle diffusion panelsare arranged on the two sides of the front panel, the front panel is enabled to protrude outwards; the sound box also comprises a high-pitch loudspeaker, a medium-pitch loudspeaker and a low-pitch loudspeaker, wherein the high-pitch loudspeaker, the medium-pitch loudspeaker and the low-pitch loudspeaker are arranged on the angle diffusion panels and the front panel, the sound diffusion system comprises a plurality of sound boxes, and the problems that an existing sound box is small in radiation angle, a sound box system is difficult to debug, a sound field in a room where the sound box is located is disordered and the like are solved.

Description

technical field [0001] The invention relates to a sound box, and also relates to a sound diffusion system. Background technique [0002] In the existing KTV box, the speakers are usually hung on the four corners of the room or the left and right sides of the main visual wall through the hanging ribs or the top backboard. Through the adjustment of the angle, the sound can cover the whole room. Figure 1(a) and Figure 1(b) illustrate the arrangement of speakers in the prior art, and Figure 1(a) illustrates the implementation of the prior art in which the speakers are arranged on both sides of the main visual wall, as shown in Figure 1(a ), two speakers 300 are hung on both sides of the main visual wall, and the sound radiation surface forms an included angle by inclining the angle, and the purpose of full coverage of the room is achieved by using the combined effect of direct and reflected sound; Figure 1(b ) shows the implementation form in which speakers are arranged at the ...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from Figure 1(a) and Figure 1(b) that because the radiation angle of the speaker itself is small, after the adjustment of the angle, the radiation areas of each speaker overlap each other, forming a point sound source radiation area in the sound field, In the sound overlapping area, radiation blind area and complete reflection area, due to the different ratio of direct sound or reflected sound in each area, the sound clarity of each area is different; due to the different sound energy superposition of each area, resulting The sound pressure of each partition is different; due to the different radiation intersection points of each speaker, the drift of the sound image positioning in the room is caused. Combining the above reasons, the sound field in the room is finally chaotic, which affects the overall listening and singing experience. Effect

[0004] In addition, in the existing installation method of the speaker, it is very easy to be disturbed by external conditions during actual operation, resulting in uneven hanging points and large angle variables, forming various uncontrollable variable factors, which will ultimately cause problems for later debugging. And use brings unpredictable risks, cannot form a fixed standard, and is not conducive to large-scale promotion and application
