[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 5, the speaker box includes a first housing 1, a second housing 2 assembled with the first housing 1 to form a containing cavity 10, and a sound generating unit 3 disposed in the containing cavity 10, wherein the containing cavity 10 is divided into a front cavity 10A and a rear cavity 10B by the sound generating unit 3.

The first housing 1 has a bottom wall 11 disposed opposite to the second housing 2, and a side wall 13 extending from an outer peripheral edge of the bottom wall 11 to the second housing 2.

The side wall 13 is stretched in a direction away from the housing chamber 10 to form a stepped portion 15.

The step part 15 comprises a step surface 151 facing the second shell 2, and the second shell 2 is welded and fixed on the step surface 151 and surrounds the side wall 13 to form a glue containing groove 5. Sealing between the first housing 1 and the second housing 2 can be achieved by applying glue in the glue receiving slot 5.

In the present embodiment, the second housing 2 is laser-welded and fixed to the stepped surface 151.
