[0006] Furthermore, a plurality of the first air guiding holes are opened on the rear wall of the speaker box, and the plurality of the first air guiding holes are evenly arranged on the rear wall.

[0007] Furthermore, at least one second air guide hole is provided on the side wall of the speaker box.

[0008] Furthermore, a plurality of the second air guiding holes are opened on the side box wall of the speaker box body, and the plurality of the second air guiding holes are evenly arranged on the side box wall.

[0009] Furthermore, the side box wall is provided with grooves at opposite ends of the outer wall, and a spring clamping structure mounting portion is provided in the groove.

[0010] Compared with the prior art, the beneficial effects of the ceiling speaker of the utility model are as follows:

[0011] 1. The ceiling speaker of the utility model can minimize the acoustic short circuit phenomenon and present complete sound quality by arranging a speaker in the box body compared with ordinary ceiling speakers.

[0012] 2. A ceiling speaker of the utility model is provided with a first air guide hole on the rear wall of the speaker box. Low-frequency airflow enters the ceiling through the first air guide hole, making the ceiling another large box. The speaker box and the ceiling work at the same time to better restore the low-frequency sound quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0019] In view of the technical problems in the background technology, the embodiment of the utility model provides a ceiling speaker, which is fixed on the installation hole of the ceiling. Figure 1-2 As shown, in one embodiment, the ceiling speaker includes a speaker box 1 and a speaker 2. The speaker box 1 includes a front box wall 11, a side box wall 12 and a rear box wall 13. The speaker 2 is arranged on the front box wall 11 of the speaker box 1. The speaker 2 is specifically a circular speaker 2 or an elliptical speaker 2. At least one first air guide hole 14 is opened on the rear box wall 13 of the speaker box 1. After the speaker 2 generates low-frequency airflow, the low-frequency airflow enters the ceiling through the first air guide hole 14, so that the ceiling becomes another large box. The speaker box 1 and the ceiling act simultaneously to achieve a more complete restoration of the low-frequency sound quality.

[0020] Preferably, if Figure 2As shown, a plurality of first air guide holes 14 are opened on the rear wall 13 of the speaker box 1, and the plurality of first air guide holes 14 are evenly arranged on the rear wall 13. The low-frequency airflow enters the ceiling through the plurality of first air guide holes 14, realizing faster airflow and restoring stronger low-frequency sound quality.

[0021] In one embodiment, at least one second air guide hole (not shown) may be provided on the side wall 12 of the speaker box 1, and low-frequency airflow may flow from the speaker box 1 to the ceiling in multiple directions to achieve better sound quality restoration. More preferably, a plurality of second air guide holes are provided on the side wall 12 of the speaker box 1, and the plurality of second air guide holes are evenly arranged on the side wall 12.

[0022] like Figure 2 As shown, in one embodiment, the side box wall 12 is provided with grooves 15 at opposite ends of the outer wall, and a spring clamping structure mounting portion 16 is provided in the groove 15. The existing spring clamping structure can be installed on the spring clamping structure mounting portion 16, and the groove 15 on the side box wall 12 can protect the spring clamping structure.

[0023] Compared with the prior art, the beneficial effects of a ceiling speaker in the embodiment of the utility model are as follows:

[0024] 1. A ceiling speaker box according to an embodiment of the utility model can minimize the phenomenon of acoustic short circuit and present complete sound quality by arranging a speaker in the box body, compared with ordinary ceiling speakers.

[0025] 2. A ceiling speaker in an embodiment of the utility model is provided with a first air guide hole on the rear wall of the speaker box. Low-frequency air flows into the ceiling through the first air guide hole, making the ceiling another large box. The speaker box and the ceiling act at the same time to better restore the low-frequency sound quality.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
