The provision of the partition wall 15 can be used to restrict the movement of the speaker unit 30 on the one hand, and can also restrict the sound-absorbing material outside the partition wall 15 from entering the speaker unit 30 on the other hand. The isolation net 20 is directly connected with the isolation wall 15, so that the number of parts during assembly is reduced, the assembly difficulty is reduced, the assembly efficiency of operators can be improved, and the productivity of the loudspeaker box is improved.

Referring to fig. 5 to 8, the through holes 21 on the separation net 20 are kidney-shaped holes, which facilitate the arrangement of the electrical connectors 40 electrically connected to the positive and negative electrodes of the speaker unit 30, respectively. Preferably, the shape of the electrical connector 40 is matched with the structural shape of the through hole 21, which facilitates the sealing between the electrical connector 40 and the isolation net 20, and prevents sound-absorbing material from entering the accommodating cavity 111 through the through hole 21, thereby ensuring the reliability of the operation of the speaker unit 30. In particular, the electrical connection 40 may be a cable.
