[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] See Figure 1-2 This utility model provides an assembly structure 100 for a housing, a sound cavity 20, and a speaker 30. The assembly structure 100 includes a housing 10, a sound cavity 20 disposed within the housing 10, and a speaker 30 disposed within the sound cavity 20. The sound cavity 20 is a hollow structure that forms a receiving space for accommodating the speaker 30. The sound cavity 20 is also provided with an assembly surface, and a plurality of fixing posts 23 are provided on the assembly surface. The housing 10 is provided with a plurality of mounting posts 13 for cooperating with the fixing posts 23. A locking member 40 passes through the mounting posts 13 and locks itself within the fixing posts 23, thereby fixing the housing 10 to the sound cavity 20 and the speaker 30. The assembly structure 100 of the housing and the speaker 30 provided by this utility model uses a locking member 40 to pass through the mounting post 13 of the housing 10 and lock it in the fixing post 23 of the speaker 20. This makes the housing 10 fixedly connected to the speaker 30 and the speaker 30 located in the accommodating space of the speaker 20. This can effectively improve the utilization rate of the internal space of the housing 10, make the structure of the entire audio system more stable, reduce the changes in sound quality caused by vibration or impact, and improve the clarity and layering of the sound. In addition, it can reduce the number of parts required for production, reduce material costs, and simplify the production process and assembly steps, thereby effectively improving production efficiency and reducing labor costs.

[0024] like Figure 1As shown, in the embodiment provided by this utility model, the fixing post 23 on the housing 10 and the mounting post 13 on the mounting surface of the sound cavity 20 are coaxially arranged. By coaxially arranging the fixing post 23 on the housing 10 and the mounting post 13 on the mounting surface of the sound cavity 20, the coaxiality between the fixing post 23 and the mounting post 13 can be effectively guaranteed, thereby effectively ensuring the accuracy of using bolts, studs, and pins and other locking components 40 to pass through the mounting post 13 and lock them in the fixing post 23. In addition, the speaker 30 has a speaker mounting surface 31, the top end of the mounting post 13 abuts against the speaker mounting surface 31, and the locking component 40 passes through the mounting post 13 and locks it in the fixing post 23, so that the housing 10 and the sound cavity 20 are fixedly connected and the mounting surface of the speaker 30 is pressed against the space between the housing 10 and the sound cavity 20. By using bolts, studs, and pins as locking components 40 to pass through the mounting post 13 and lock them into the fixing post 23, the housing 10 and the sound cavity 20 are fixedly connected, and the mounting surface of the speaker 30 is pressed against the housing 10 and the sound cavity 20. This effectively simplifies the installation structure of fixing the speaker 30 together with the housing 10 and the sound cavity 20, and makes the housing 10 and the sound cavity 20 form an integrated assembly design. This further improves the utilization rate of the internal space of the housing 10, makes the structure of the entire audio system more stable, reduces the changes in sound quality caused by vibration or impact, improves the clarity and layering of the sound, and simplifies the production process and assembly steps. While effectively improving production efficiency, it also reduces labor costs.

[0025] like Figure 1 and Figure 2As shown, the mounting post 13 provided by this utility model is provided with a mounting platform 131. The top of the mounting platform 131 and the inner wall of the mounting post 13 enclose a mounting groove for the bottom of the fixing post 23 to be embedded. By embedding the bottom of the fixing post 23 of the sound cavity 20 into the mounting groove formed by the top of the mounting platform 131 and the inner wall of the mounting post 13, the coaxiality between the fixing post 23 and the mounting post 13 can be further guaranteed, thereby further ensuring the accuracy of using bolts, studs, and pins and other locking components 40 to pass through the mounting post 13 and lock it in the fixing post 23, as well as the convenience of operation. The bottom end of the mounting platform 131 and the inner wall of the mounting post 13 enclose a locking space for the locking component 40 to pass through, and a locking hole for the locking component 40 to pass through is provided at the center of the mounting platform 131. The locking component 40 is a bolt. The stud end of the bolt passes through the locking hole of the mounting platform 131 and is locked inside the fixing post 23, while the nut end of the bolt abuts against the bottom of the mounting platform 131. By passing the stud end of the bolt through the locking hole of the mounting platform 131 and locking it inside the fixing post 23, the stability of the housing 10 and the sound cavity 20 can be effectively ensured, as well as the stability of the housing 10 and the sound cavity 20 being fixedly connected and forming an integrated assembly design. The nut end of the bolt abutting against the bottom of the mounting platform 131 can effectively improve the convenience of the operator when tightening the bolt and improve installation efficiency.

[0026] like Figure 2As shown, in the embodiment provided by this utility model, the housing 10 includes an upper housing 11 and a lower housing 12. The upper housing 11 has a housing mounting groove 111, and the lower housing 12 is provided with a housing mounting platform 121. By cooperating the housing mounting groove 111 of the upper housing 11 with the mounting platform 131 on the lower housing 12, the upper housing 11 and the lower housing 12 are snapped together and fixed. This ensures the stability of the snap-fit ​​fixation between the upper housing 11 and the lower housing 12, while effectively simplifying the installation structure between the upper housing 11 and the lower housing 12 and improving the installation efficiency. Furthermore, the acoustic cavity 20 includes an upper acoustic cavity 21 and a lower acoustic cavity 22. The lower acoustic cavity 22 has an acoustic cavity mounting groove 221, and the upper acoustic cavity 21 is provided with an acoustic cavity mounting platform 211. By cooperating the acoustic cavity mounting groove 221 of the lower acoustic cavity 22 with the mounting platform 131 on the upper acoustic cavity 21, the upper acoustic cavity 21 and the lower acoustic cavity 22 are snapped and fixed. This effectively ensures the stability of the snapping and fixing between the upper acoustic cavity 21 and the lower acoustic cavity 22, simplifies the installation structure between the upper acoustic cavity 21 and the lower acoustic cavity 22, improves installation efficiency, and forms an ultrasonic acoustic cavity 20, thereby further improving the clarity and layering of the sound. In the embodiment provided by this utility model, an EVA sealing gasket 50 is also provided between the speaker mounting surface 31 and the acoustic cavity 20. The EVA sealing gasket 50 can effectively improve the sound insulation effect, thereby preventing the sound emitted by the speaker 30 from flowing out of the gap between the speaker mounting surface 31 and the sound cavity 20. This ensures that the sound emitted by the speaker 30 flows within the ultrasonic sound cavity 20 formed by the upper sound cavity 21 and the lower sound cavity 22, thereby further improving the clarity and layering of the sound and ensuring the user's experience during use.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
