The loudspeaker box 10 comprises a shell 100 and a loudspeaker 200, the loudspeaker 200 is arranged in the shell 100, the shell 100 is provided with a first sound cavity 110 and a second sound cavity 120, the first sound cavity 110 and the second sound cavity 120 are arranged on two sides of the loudspeaker 200 at intervals in the radial direction X of the loudspeaker 200, the axial direction Y of the first sound cavity 110 and the second sound cavity 120 is parallel to the axial direction Y of the loudspeaker 200, and the side walls of the first sound cavity 110 and the second sound cavity 120 are respectively provided with a sound inlet 130 for communicating the loudspeaker 200.

The housing 100 may include an upper case 101 and a lower case 102, and the upper case 101 and the lower case 102 may be detachably coupled to each other so as to form the first and second sound chambers 10 and 120 while facilitating the installation of the speaker 200 in the housing 100. The first sound chamber 110, the speaker 200, and the second sound chamber 120 are arranged in the radial direction X of the speaker 200, and it is easier to design the cabinet 10 to be flattened and to make the cabinet 10 slim, compared to arranging the first sound chamber 110, the speaker 200, and the second sound chamber 120 in the axial direction Y of the speaker 200. Meanwhile, the axial directions Y of the first sound cavity 110 and the second sound cavity 120 are parallel to the axial direction Y of the loudspeaker 200, so that the first sound cavity 110, the loudspeaker 200 and the second sound cavity 120 are more regularly arranged, and the volume of the loudspeaker box 10 is further reduced. Meanwhile, the first sound cavity 110 and the second sound cavity 120 are provided with the sound inlet 130 on the respective side walls for communicating with the loudspeaker 200, so that the sound quality of the loudspeaker box 10 can be improved.

Meanwhile, the first sound cavity 110 and the auxiliary sound outlet 220 of the loudspeaker 200 form a closed space, and the second sound cavity 120 and the main sound outlet 210 of the loudspeaker 200 form a closed space, so that the problems of insufficient low-frequency extension and excessive high-frequency extension of the loudspeaker 10 can be solved, and the low-frequency and high-frequency extension can be effectively widened through the structure of the loudspeaker 10 so as to provide the sound quality of the loudspeaker 10.
