It is understood that, when the first housing 100 is provided with the first rib 120, the second housing 200 is provided with the second rib 210, and the second rib 210 is protruded toward the first housing 100. When the second housing 200 is provided with the first ribs 120, the first housing 100 is provided with the second ribs 210, and the second ribs 210 are protruded toward the second housing 200. The second rib 210 is located in the sound cavity 600 or the second rib 210 is located outside the sound cavity 600, and the second rib 210 is adjacent to the first rib 120. Thus, by providing the second rib 210, the sealing property of the sound chamber 600 can be further improved, and the sound can be blocked from being transmitted from the free end of the first rib 120.

For example, as shown in fig. 1 to 3, a side of the first housing 100 facing the second housing 200 may be provided with a first rib 120, and an end of the first rib 120 away from the first housing 100 extends toward the second housing 200.

second housings

100 and 200, and the first and

second chambers

610 and 620 may be configured by the horn assembly 300 and the bracket 400.

As shown in fig. 3, in some embodiments of the present application, the connecting portion of the first casing 100 and the second casing 200 has a notch 160, and the other end of the bracket 400 is located in the notch 160. It is understood that an end of the bracket 400 remote from the horn assembly 300 may extend toward a connection position of the first and

second housings

100 and 200. A gap 160 may be provided at a connection position of the first casing 100 and the second casing 200. For example, the first housing 100 may be provided with a notch 160. Or the second housing 200 is provided with the notch 160. For another example, the first housing 100 and the second housing 200 together form the gap 160.
