Detailed Description

To facilitate understanding of those skilled in the art, the present invention is described in further detail below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, a multi-sound-cavity loudspeaker box comprises a box body 1 which is transversely arranged, wherein a main sound cavity 2 is arranged on the front end surface of the box body 1, the main sound cavity 2 is provided with two loud speakers 3, and the two loud speakers 3 are symmetrically arranged in the left-right direction. A protruding part 4 is arranged between the two big horns 3, and a central horn 5 is arranged on the protruding part 4. Protruding portion 4 can play the effect of separating main sound chamber 2 for two loud speakers 3 are located comparatively independent sound intracavity, and bellying 4 still can make central loudspeaker 5 antedisplacement, thereby makes can not interfere with each other between central loudspeaker 5 and the loud speaker 3, is equivalent to being located independent sound intracavity, and the sound production of front and back different faces has also promoted the stereo effect.

Two installing supports 6 are arranged in the main sound cavity 2, the two installing supports 6 are erected in the dead ahead of the two loud speakers 3 respectively, small speakers 7 are arranged on the two installing supports 6, the small speakers 7 are located in the front of the loud speakers 3, a plurality of sound producing points are formed in a limited space, the positions of the sound producing points are staggered, and the stereo effect is further improved.
