[0021] In order to make the objectives, technical solutions, and advantages of this application clearer, the following further details this application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0022] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0023] It should also be noted that the orientation terms such as left, right, up, and down in the embodiments of the present application are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0024] Please refer to Figures 3 - 7 , the present application provides a speaker, including a sound cavity 10 and an air duct 20. The air duct 20 is communicatively connected to the sound cavity 10. Preferably, the air duct 20 and the sound cavity 10 are integrally formed. The air duct 20 includes a first wall 21 and a second wall 22; one end of the first wall 21 is connected to the sound cavity 10, and the other end first bends upward and then extends parallel to the sound cavity 10 away from the sound cavity 10. The second wall 22 is connected to and close to the sound cavity 10, is disposed opposite to the first wall 21, and forms an air duct with the first wall 21; the speaker further includes a connecting member 30, which is disposed at the connection between the second wall 22 and the sound cavity 10, near one end inside the sound cavity 10, and the side of the connecting member 30 opposite to the first wall 21 has a smooth arc.

[0025] For the speaker provided by the present application, the integral formation of the sound cavity 10 and the air duct 20 can reduce the production and manufacturing cost of the speaker. In addition, by providing a connecting member 30 with a smooth arc at the inner corner of the sound cavity 10 and the air duct 20, it is possible to avoid the problem in the prior art that the sharp corners at the corner of the sound cavity 10 and the air duct 20 increase the wind noise and affect the sound effect of the product.

[0026] In a specific embodiment, the second wall 22 of the air duct 20 and the outer wall of the sound cavity 10 are integrated; the connecting member 30 is connected to one end of the second wall 22 close to the inside of the sound cavity 10. Integrating the second wall 22 of the air duct 20 and the outer wall of the sound cavity 10 can, on the one hand, facilitate the processing and manufacturing of the product, and on the other hand, reduce the manufacturing cost of the product.

[0027] Preferably, as Figure 3 shown, the connecting member 30 has the same arc as the first wall 21 of the air duct 20 opposite to it, that is, the arc of the inscribed circle of the connecting member 30 is the same as the arc of the first wall 21 and is mirror-symmetrical. In this embodiment, by setting the arc of the connecting member 30 to be the same as the bending arc of the first wall 21 of the air duct and mirror-symmetrical, a smooth air duct is formed, so that the resistance suffered by the sound wave during the propagation in the sound channel is minimized, thereby reducing the noise generated by the sound wave passing through the air duct and improving the sound effect of the speaker.

[0028] In a specific embodiment, as Figure 3, 4 As shown, the connecting member 30 is fixedly connected to the second wall 22 or the inner wall of the sound cavity 10 by screws. Further, a sealing colloid is provided at the connection between the connecting member 30 and the second wall 22 or the inner wall of the sound cavity 10. In other embodiments, the connecting member 10 can also be directly connected to the second wall 22 or the inner wall of the sound cavity 10 by a sealing colloid. Thereby, the sealing performance at the connection between the connecting member 30 and the second wall 22 or the inner wall of the sound cavity 10 can be improved, and air leakage in the air duct can be avoided from affecting the sound effect.

[0029] As Figures 5 - 7 shown, in one embodiment, the speaker further includes a speaker 50, and the speaker 50 is disposed on the opposite wall of the sound cavity 10 to the air duct 20. For example, the speaker 50 is disposed on the front wall of the sound cavity 10, the air duct is disposed on the rear wall of the sound cavity, and the air outlet of the air duct is disposed on the side wall of the sound cavity. Preferably, the diameter of the air inlet at the connection end of the air duct and the sound cavity is larger than the diameter of the air outlet. In addition, the speaker further includes a housing 40, and the housing 40 is disposed outside the speaker 50. The speaker 50 vibrates back and forth to generate sound waves. The sound waves emitted forward are directly transmitted into the air, and the sound waves generated backward are led out from the sound cavity 10, and are emitted from the side wall of the speaker after passing through the air duct 20. Thereby, the backward vibration sound waves can be effectively utilized, and the sound waves transmitted to the user are enhanced. In this way, the sound waves in both the forward and backward directions of the speaker 50 are utilized, thereby improving the sound quality of the speaker.

[0030] The speaker provided by this application can take into account the product manufacturing cost while avoiding the problem that the sound quality of the speaker deteriorates due to structural problems caused by production and manufacturing.

[0031] The above are only the preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent replacements, or improvements made within the spirit and principle of this application shall be included within the protection scope of this application.
