In this embodiment, the front ends of the two extension walls 130 extend toward each other, and a stopper groove 131 is formed between the extension walls 130 and the front side surface of the housing 100. Specifically, the front end of the upper extension wall 130 protrudes downward, and the front end of the lower extension wall 130 protrudes upward. The protrusion forms a stopper groove 131 between the corresponding extension wall 130 and the front side surface of the housing 100, and the stopper groove 131 extends to both left and right ends of the housing 100.

In some embodiments, an upper edge or a lower edge of the front side of the housing 100 extends forward in the limiting groove 131, and a step is formed at the front side of the housing 100 to adjust the size of the limiting groove 131.

Referring again to fig. 3 to 5, the plurality of speakers includes a center channel speaker 410 and two left and right channel speakers 420; the center channel speaker 410 is a woofer, which is a center channel. The left and right channel speakers 420 are tweeters. Two left and right channel speakers 420 are located on the left and right sides of the center channel speaker 410, respectively, to form front left and right channels. The center channel speaker 410 and the two left and right channel speakers 420 are respectively located in one accommodating cavity 110, and a window 120 opened forward is correspondingly arranged in the accommodating cavity 110; the center channel speaker 410 and the two left and right channel speakers 420 are fixed at the corresponding front-side opening windows 120, respectively, to emit sound forward.

In this embodiment, the center speaker 410 is located in the middle of the housing 100. In some embodiments, a subwoofer is also disposed within the housing 410. The subwoofer is located in a single chamber 120 and the center speakers 410 are located on the left and right sides of the enclosure.

Referring to fig. 2 to 5, a window 120 is disposed on an upper surface of at least one of the accommodating cavities 110, a sky sound channel speaker 430 is disposed at the window 120, and the sky sound channel speaker 430 is used for providing a sky sound to enhance a sound channel performance of the sound bar. An inclined bracket 800 is fixed on the window 120; the sky sound channel speaker 430 is fixed to the tilt bracket 800 to be tilted forward and upward to output sound. After the sky sound channel speaker 430 is fixed to the tilting bracket 800, the tilting bracket 800 passes through the corresponding window 120 to drive the sky sound channel speaker 430 to tilt and set on the housing 100.

In this embodiment, two sky sound channel speakers 430 are provided, and the two sky sound channel speakers 430 are respectively provided near the left and right ends of the casing 100. In some embodiments, the sky channel speakers 430 may be set to one.

In this embodiment, the sky sound channel speaker 430 and the left and right channel speakers 420 on the left and right sides of the casing 100 are located in the same accommodating cavity 110, so that the sound bar has a compact structure, and the casing 100 can be set to have a smaller length and volume. The inclined bracket 800 alone forms a closed space, effectively preventing the sky sound channel speaker 430 and the left and right channel speakers 420 from interfering with each other.

In some embodiments, the sky sound channel speaker 430 and the left and right channel speakers 420 are respectively accommodated in different accommodating cavities 110, so that the operation of the sky sound channel speaker 430 and the left and right channel speakers 420 is not affected by each other, and the sound quality of the sound bar is better.
