They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 A loudspeaker with a highly efficient dustproof structure includes a loudspeaker body 1, a frame 2 at the upper end of the loudspeaker body 1, a dustproof tuning cover 3 at the upper end of the frame 2, two symmetrically distributed rectangular slots 4 at the upper end of the loudspeaker body 1 away from the center, a circular cover 5 being snapped into the two rectangular slots 4, and rectangular blocks 8 inserted into each of the two rectangular slots 4. The lower end of the circular cover 5 is fixedly connected to the upper end of the two rectangular blocks 8, and circular grooves 9 are provided on the opposite inner walls of the two rectangular slots 4. Springs 10 are fixedly connected to the opposite inner walls of the two circular grooves 9, and cylindrical blocks 11 are fixedly connected to the ends of the two springs 10 away from the inner walls of the circular grooves 9. Circular through slots 12 are provided on the two rectangular blocks 8, with the two rectangular slots 4 facing the inner walls of the circular grooves 9. The wall is provided with circular holes 13. Two cylindrical blocks 11 are respectively set through two circular slots 12 and circular holes 13. The circular cover 5 is connected to the basket 2 on the speaker body 1, so that the two rectangular blocks 8 at the lower end of the circular cover 5 are respectively inserted into the two rectangular slots 4 on the basket 2. Press the cylindrical blocks 11 in the two rectangular slots 4 and compress the spring 10 in the circular opening 6 until the rectangular blocks 8 can be fully inserted into the rectangular slots 4. At this time, the compressed spring 10 elastically returns to its original position, causing the rectangular blocks 8 to pass through the circular slots 12 on the rectangular blocks 8 and the circular holes 13 in the rectangular slots 4, effectively fixing the circular cover 5 on the basket 2. This allows the dustproof tuning cover 3 and the circular dustproof mesh 16 on the circular cover 5 to provide double-layer dust filtration for the speaker body 1, improving the dustproof effect.
[0023] The rectangular insert 8 is welded and fixed to the circular cover 5. The diameters of the circular groove 9, the circular through groove 12, and the circular hole 13 are equal. The upper end of the frame 2 is fixedly connected to the first annular sealing ring 14. The dustproof tuning cover 3 is located inside the first annular sealing ring 14. The second annular sealing ring 15 is fixedly connected to the annular inner wall of the circular cover 5 near the lower end. The first annular sealing ring 14 and the second annular sealing ring 15 slide and seal against each other. The first annular sealing ring 14 and the second annular sealing ring 15 are both corrosion-resistant rubber products. The first annular sealing ring 14 and the second annular sealing ring 15 made of corrosion-resistant rubber products can provide a seal for the gap between the circular cover 5 and the speaker body 1, preventing dust and other impurities from entering the frame 2 along the gap.
[0024] A circular opening 6 is provided at the upper end of the center of the circular cover 5. A dustproof component is provided inside the circular opening 6. The dustproof component includes a circular dustproof mesh 16 inserted into the circular opening 6. A first annular magnetic sheet 17 is fixedly connected to the bottom of the circular opening 6. The first annular magnetic sheet 17 is arranged around the circular sound-transmitting opening 7. A second annular magnetic sheet 18 is fixedly connected to the lower end of the circular dustproof mesh 16 inside the circular opening 6. The first annular magnetic sheet 17 and the second annular magnetic sheet 18 have opposite magnetic properties and are attracted and fixed. The circular sound-transmitting opening 7 is located at the bottom of the center of the circular opening 6. When the circular dustproof mesh 16 is inserted into the circular opening 6 on the circular cover 5, the first annular magnetic sheet 17 on the circular dustproof mesh 16 and the second annular magnetic sheet 18 inside the circular opening 6 are attracted and fixed, effectively positioning the circular dustproof mesh 16 inside the circular opening 6. This facilitates the removal and replacement of the circular dustproof mesh 16 and the circular cover 5 for cleaning. The structure is simple and practical.
[0025] In use, the circular cover 5 is aligned with the speaker frame 2 on the speaker body 1, so that the two rectangular inserts 8 at the lower end of the circular cover 5 are respectively inserted into the two rectangular slots 4 on the speaker frame 2. The cylindrical locking blocks 11 in the two rectangular slots 4 are pressed and the spring 10 in the circular opening 6 is compressed until the rectangular inserts 8 can be fully inserted into the rectangular slots 4. At this time, the compressed spring 10 elastically returns to its original position, causing the rectangular inserts 8 to pass through the circular through groove 12 on the rectangular inserts 8 and the circular hole 13 in the rectangular slots 4, effectively fixing the circular cover 5 onto the speaker frame 2, so that the dustproof tuning cover 3 and the circular dustproof mesh 16 on the circular cover 5 are aligned. The main body 1 provides double-layer dust filtration to improve dust prevention. When disassembling, simply press the two cylindrical clips 11 again to separate them from the circular slot 12 and the circular hole 13. Pull the circular cover 5 to separate the rectangular insert 8 from the rectangular slot 4. This makes it easy to clean the dustproof tuning cover 3 after disassembling the circular cover 5. Insert the circular dustproof mesh 16 into the circular opening 6 on the circular cover 5 so that the first annular magnetic piece 17 on the circular dustproof mesh 16 is attracted and fixed to the second annular magnetic piece 18 in the circular opening 6. This effectively positions the circular dustproof mesh 16 in the circular opening 6, making it easy to replace the circular dustproof mesh 16 and the circular cover 5 for cleaning. The structure is simple and practical.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
