Detailed Implementation

[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0029] A quick-connect speaker tube includes a speaker tube bottom cover 1. A channel cover plate 2 is provided on one side of the speaker tube bottom cover 1. A plug-in part 3 is fixedly connected to one side of the speaker tube bottom cover 1. One side of the plug-in part 3 is inserted into the interior of the channel cover plate 2. A slot 4 is provided on both sides of the plug-in part 3. A locking groove 5 is provided on one side of the inner cavity of the slot 4. A sliding hole 6 is provided on one side of the inner cavity of the locking groove 5. A positioning pin 7 is slidably installed in the inner cavity of the sliding hole 6. A spring 8 is fixedly connected to one end of the positioning pin 7. One end of the spring 8 is fixedly connected to the inner wall of the sliding hole 6. Locking blocks 16 that are adapted to the slot 4 and locking groove 5 are fixedly connected to both sides of the inner cavity of the channel cover plate 2. A positioning groove 17 that is adapted to the positioning pin 7 is provided on one side of the locking block 16.

[0030] The specific usage process is as follows: It should be noted that the positioning pin 7 is directly inserted into the positioning groove 17 and, under the action of the spring 8, will not easily move out of the positioning groove 17. The locking block 16 is engaged in the locking groove 5 and will not easily move axially or laterally. Under the action of the positioning pin 7, it will also not easily rotate. Therefore, the locking block 16 is difficult to move out of the slot 4. Thus, without the user actively and forcefully rotating the speaker base cover 1 or the channel cover 2, the speaker base cover 1 will not disassemble from the channel cover 2, ensuring the firmness and stability of the assembly of the speaker base cover 1 and the channel cover 2. When the channel cover 2 is damaged, that is, when a vulnerable part of the speaker is damaged, the user can hold the speaker base cover 1 in place with one hand, and then... With the other hand, rotate the channel cover 2. Because the positioning pin 7 is inserted into the positioning groove 17, the user needs to rotate the channel cover 2 with force. The user can determine the specific force according to the actual operation needs. As the channel cover 2 is rotated, the positioning pin 7 will be squeezed by the locking block 16, and then the positioning pin 7 will move out of the positioning groove 17, thereby retracting into the inner cavity of the sliding hole 6. At the same time, the spring 8 is compressed, and then the locking block 16 will move out of the inner cavity of the locking groove 5. At this time, the channel cover 2 can be moved to one side and removed. During the process of removing the channel cover 2, the locking block 16 will pass through the slot 4 and move out of the slot 4. This completes the disassembly of the channel cover 2. It should be noted that the channel cover 2 and the speaker tube 1 integrally formed on the channel cover 2 are also included. Part 8 is the most vulnerable part. Therefore, after removing the channel cover 2, a new channel cover 2 can be installed. This method does not require disassembling all other components inside the speaker tube bottom cover 1, saving a significant amount of maintenance time and allowing for quick maintenance and replacement of the speaker tube. It not only allows for quick disassembly but also quick reassembly. During assembly, align the channel cover 2 with the speaker tube bottom cover 1. The connector 3 on the speaker tube bottom cover 1 will insert into the channel cover 2. At this time, the locking block 16 will insert into the slot 4 and then pass through the slot 4 into the locking groove 5. It should be noted that the ball bearing 12 on the connector 3 must also be aligned with the groove 11. After the locking block 16 is engaged in the locking groove 5, the ball bearing 12 will also pass through the groove. 11 is inserted into the fitting groove 10, and then the channel cover 2 is rotated. At this time, the locking block 16 will enter the locking groove 5. During this process, the locking block 16 will press the positioning pin 7, and the positioning pin 7 will retract into the sliding hole 6. At the same time, the spring 8 is compressed. When the positioning groove 17 is aligned with the positioning pin 7, under the action of the spring 8, the positioning pin 7 is ejected from the inner cavity of the sliding hole 6 and finally inserted into the positioning groove 17, thereby fixing the locking block 16 in the locking groove 5, completing the assembly of the channel cover 2 and the speaker tube bottom cover 1. At the same time, the ball bearing 12 will also move away from the position of the groove 11, but at the same time, the ball bearing 12 will still slide in a rolling state within the fitting groove 10. This ensures the smoothness and flexibility of the installation and rotation of the channel cover 2, while also providing a limiting and positioning function for the channel cover 2.In other words, when the ball bearing 12 is not aligned with the groove 11, the ball bearing 12 remains locked within the fitting groove 10, thus preventing the channel cover 2 from moving freely. After the channel cover 2 is fully fitted onto the insertion part 3, the end of the insertion part 3 will abut against the retaining flange 9. In this way, the retaining flange 9 can limit the installation of the channel cover 2, ensuring the tightness of the connection and assembly between the channel cover 2, the speaker tube bottom cover 1, and the insertion part 3, providing convenience for the user's installation work. When the channel cover 2 is fully fitted onto the insertion part 3, the ball bearing 12 also engages in the fitting groove 10. With the locking block 16 aligned with the locking groove 5, when the user rotates the channel cover 2 to engage the locking block 16 into the locking groove 5, the ball bearing 12 will also move within the adapting slide 10, thus limiting the locking block 16 and ensuring that the movable word module area 15 can be precisely and smoothly engaged into the locking groove 5. This improves the installation speed of the channel cover 2 and provides convenience for the user's installation work. The groove 11 is used for the ball bearing 12 to engage. When installing the channel cover 2, align the groove 11 with the ball bearing 12 so that the channel cover 2 can be easily engaged. Connecting to the connector 3 ensures that the locking block 16 can smoothly engage with the slot 4, thus providing guidance and limitation for the installation of the channel cover 2, facilitating user installation. The speaker tube 18 connects to the port 13 on the channel cover 2 and is integrally formed and connected to the channel cover 2. This allows the sound generated by the speaker tube to be diffused and conducted out through the speaker tube 18, providing convenience for user operation. The vent 14 guides airflow; when the speaker operates in a high-temperature environment, the high-temperature airflow generated inside can be discharged to the outside through the vent 14, thereby balancing the temperature inside and outside the speaker tube and ensuring its normal operation, providing convenience for user operation. Movable word module area one 15 and movable word module area two 19 are used to display lettering information. Product parameters and other information can be displayed in these areas for user information. Furthermore, this lettering information can be changed and adjusted according to different product models, providing convenience for user production.

[0031] Therefore, a detachable speaker tube structure is adopted, dividing the speaker tube into a main body that houses the internal components and a easily damaged part. The easily damaged part can be quickly disassembled from the main body for replacement, reducing maintenance costs, improving the efficiency of speaker tube maintenance and replacement, and providing convenience for users' maintenance work.

[0032] The inner cavity of the sound channel cover plate 2 is integrally formed with a retaining flange 9 that is adapted to the insertion part 3. The inner diameter of the retaining flange 9 is the same as the inner diameter of the insertion part 3.

[0033] Specifically, the flange 9 is designed so that after the channel cover 2 is fully fitted onto the plug part 3, the end of the plug part 3 will abut against the flange 9. In this way, the flange 9 can limit the installation of the channel cover 2, ensuring the tightness of the connection and assembly between the channel cover 2, the speaker tube bottom cover 1, and the plug part 3, and providing convenience for the user's installation work.

[0034] The inner wall of the sound channel cover plate 2 is provided with a matching groove 10, and the surface of the plug part 3 is embedded with a ball bearing 12 that matches the matching groove 10.

[0035] Specifically, with the adaptation groove 10 and ball bearing 12 in place, when the channel cover 2 is fully fitted onto the plug part 3, the ball bearing 12 also engages within the adaptation groove 10, and the locking block 16 aligns with the locking groove 5. When the user rotates the channel cover 2 to engage the locking block 16 within the locking groove 5, the ball bearing 12 also moves within the adaptation groove 10, thus limiting the locking block 16 and ensuring that the movable word module area 15 can be precisely and smoothly engaged within the locking groove 5. This improves the installation speed of the channel cover 2 and provides convenience for the user's installation work.

[0036] The inner wall of the sound channel cover plate 2 is provided with a plurality of grooves 11 that communicate with the matching slide groove 10, and the grooves 11 are adapted to the ball bearings 12.

[0037] Specifically, the groove 11 is designed to allow the ball bearing 12 to engage. When installing the channel cover 2, the groove 11 is aligned with the ball bearing 12, so that the channel cover 2 can be smoothly engaged with the connector 3. This also ensures that the locking block 16 can be smoothly engaged with the slot 4, thereby providing guidance and limiting for the installation of the channel cover 2 and making the installation work more convenient for the user.

[0038] A port 13 is provided at the bottom of one side of the channel cover plate 2, and a speaker tube 18 communicating with the port 13 is integrally formed on one side of the bottom of the channel cover plate 2.

[0039] Specifically, regarding the configuration of port 13 and speaker tube 18, the speaker tube 18 is connected to the position of port 13 on the channel cover plate 2, and the speaker tube 18 is integrally formed and connected to the channel cover plate 2. In this way, the sound generated by the speaker tube can be diffused and transmitted through the speaker tube 18, providing convenience for the user's work.

[0040] The top of one side of the sound channel cover plate 2 is provided with multiple vent holes 14, and all of the multiple vent holes 14 are connected to the inner cavity of the sound channel cover plate 2.

[0041] Specifically, the ventilation hole 14 is designed to guide airflow. When the loudspeaker is operating in a high-temperature environment, the high-temperature airflow generated inside can be discharged to the outside through the ventilation hole 14, thereby balancing the temperature inside and outside the loudspeaker, ensuring the normal operation of the loudspeaker, and providing convenience for users.

[0042] One side of the speaker tube 18 is provided with a movable word module area 2 19, and one side of the channel cover plate 2 is provided with a movable word module area 15.

[0043] Specifically, the settings of movable text module area 15 and movable text module area 2 are both used to display text information. Product parameters and other information can be displayed in the positions of movable text module area 15 and movable text module area 2 for users to understand the product. Moreover, the text information can be changed and adjusted according to different product models, providing convenience for users' production work.

[0044] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
