[0035] In order to make the purpose, technical solution and advantages of this utility model clearer and more understandable, the following further details this utility model in conjunction with the accompanying drawings and embodiments.

[0036] Please refer to Figures 1 to 7 , and now the speaker 20 with a quick-assembly integrated air duct provided by the embodiment of this application is described. The speaker 20 with a quick-assembly integrated air duct includes: a speaker housing 10 and an integrated air duct 20.

[0037] The integrated air duct 20 is snap-fitted into the speaker housing 10. A first notch 11 is provided on the outer surface of the speaker housing 10, and a first mounting opening 12 is provided in the first notch 11. The first mounting opening 12 penetrates through the inner side surface of the speaker housing 10 backward; a first fitting convex ring 21 is provided at the front end of the integrated air duct 20. When the integrated air duct 20 is inserted into the first mounting opening 12, the first fitting convex ring 21 is located in the first notch 11; at least two first elastic arms 22 are provided on the rear side of the first fitting convex ring 21. Each first elastic arm 22 extends backward, and each first elastic arm 22 is provided with a first snap-fitting convex portion 23 for snapping into the inner side surface of the speaker housing 10.

[0038] Specifically, by providing the integrated air duct 20, the two first elastic arms 22 of the first fitting convex ring 21 are used to snap-fit and install the integrated air duct 20 into the first mounting opening 12; with such a structure, there is no need for screw fastening or glue fixing, which facilitates the assembly of the integrated air duct 20.

[0039] In some other embodiments of the present application, the front end of the integrated air duct 20 is larger than the rear end, so that the integrated air duct 20 can be inserted into the first mounting opening 12 from front to back, and the first fitting convex ring 21 is provided at the front end of the integrated air duct 20.

[0040] Specifically, by providing the integrated air duct 20 with a front end larger than the rear end, when assembling the integrated air duct 20, the integrated air duct 20 can be directly inserted into the speaker housing 10 from the outside through the first mounting opening 12, without the need to reach into the interior of the speaker housing 10 for assembling the air duct; with such a structure, the convenience of the operator in assembling the integrated air duct 20 can be further improved, the assembly difficulty can be reduced, and thus the assembly efficiency can be improved.

[0041] More specifically, the speaker housing 10 is provided with a first abutting convex portion 13 at the first mounting opening 12. The front surface of the first abutting convex portion 13 is flush with the front end of the first mounting opening 12; the first abutting convex portion 13 extends backward into the interior of the speaker housing 10. The rear side surface of the first abutting convex portion 13 is a first vertical abutting surface 131. The first snap-fitting convex portion 23 is provided on one side surface of each first elastic arm 22 facing the first mounting opening 12. The front surface of the first snap-fitting convex portion 23 is a second vertical abutting surface 231; when the integrated air duct 20 is inserted into the first mounting opening 12, the second vertical abutting surface 231 abuts against the first vertical abutting surface 131 to complete the snap-fitting installation of the integrated air duct 20.

[0042] Further, the front surface of the first abutting convex portion 13 is a first inclined surface 132, and the first inclined surface 132 is inclined backward from bottom to top; the rear surface of the first fastening convex portion 23 is a second inclined surface 232 adapted to the first inclined surface 132. During the process of inserting the integrated air duct 20 into the first installation opening 12, the second inclined surface 232 can abut against the first inclined surface 132.

[0043] It can be understood that when assembling the integrated air duct 20, during the process of inserting the integrated air duct 20 into the first installation opening 12 from front to back; first, the first inclined surface 132 and the second inclined surface 232 abut against each other, so that each first elastic arm 22 deforms and abuts against the side wall of the first installation opening 12; when the first fastening convex portion 23 passes through the first installation opening 12 and extends into the interior of the speaker housing 10, due to the lack of the acting force of the first installation opening 12, each first fastening convex portion 23 is buckled into the inner surface of the speaker housing 10, and the first vertical abutting surface 131 and the second vertical abutting surface 231 abut against each other to complete the buckling and assembly.

[0044] Preferably, the first abutting convex portions 13 are respectively arranged on the upper and lower sides of the first installation opening 12, the corresponding first elastic arms 22 are arranged on the upper and lower sides of the integrated air duct 20, and the first elastic arms 22 are arranged parallel to the side wall of the first installation opening 12, and the first installation opening 12 and the first notch 11 are coaxially arranged.

[0045] In some other embodiments of the present application, a first sealing ring 30 is further included, and the first sealing ring 30 is installed in the first notch 11; when the integrated air duct 20 is inserted into the first installation opening 12, the rear surface of the first sealing ring 30 abuts against the side surface of the first notch 11, and the rear surface of the first assembly convex ring 21 abuts against the front surface of the first sealing ring 30. By providing the first sealing ring 30, the functions of sealing and preventing vibration and noise can be achieved.

[0046] Specifically, when the integrated air duct 20 is inserted into the first installation opening 12 and the second vertical abutting surface 231 abuts against the first vertical abutting surface 131; the distance between the rear side surface of the first assembly convex ring 21 and the side surface of the first notch 11 is set to form a first gap, and the width w1 of the first gap is 0.2 mm - 0.3 mm, and the thickness of the first sealing ring 30 is twice that of the first gap. By providing the first sealing ring 30 with a thickness twice that of the first gap, when the integrated air duct 20 is buckled and installed on the speaker housing 10, the abutting reliability between the first vertical abutting surface 131 and the second vertical abutting surface 231 can be further improved by squeezing the first sealing ring 30, and loosening is not likely to occur; at the same time, the sealing effect of the first sealing ring 30 on the gap between the first installation opening 12 and the integrated air duct 20 can also be improved, thereby improving the waterproof effect.

[0047] In more detail, the integrated air duct 20 is integrally formed by an injection mold, and has a channel 201, which penetrates the front surface of the integrated air duct 20 to form a first opening 202, and penetrates the rear surface of the integrated air duct 20 to form a second opening 203. Since the integrated air duct 20 adopts a structure with one end larger than the other end, it is easy to demold; at the same time, the integrated molding structure does not need to be set up separately, and does not need to be fastened by screws, glue or welding later, so as to maintain the flatness in the channel 201.

[0048] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
