A connecting shell 2 is fixedly mounted to one end of each mounting shell 1. The two connecting shells 2 are snapped together to form a speaker shape. A constraint threaded cylinder 3 is threadedly connected to the outer side of each mounting shell 1. A compression cylinder 4 is fixedly mounted to one end of the constraint threaded cylinder 3 at a position corresponding to the connecting shell 2. A detachable speaker channel guiding structure is provided inside each mounting shell 1. A detachable... The speaker's sound-producing structure includes a detachable in-ear capsule structure on the speaker channel guiding structure. The speaker's sound-producing structure includes a mounting block 17, which snaps onto the end faces of two mounting shells 1. A third mounting cavity 20 is formed at one end of the mounting block 17 corresponding to one end of the mounting shell 1. A snap-fit ​​block 21 is fixedly installed on the end face of the mounting shell 1 at the position corresponding to the third mounting cavity 20. The snap-fit ​​block 21 snaps into the interior of the third mounting cavity 20. A mounting cylinder 18 is fixedly installed on the end face of the mounting block 17. The mounting cylinder 18 is a circular cylinder. A fixed speaker 19 is provided, which is installed using a mounting block 17 and a mounting cylinder 18. Anti-slip grooves 5 are equidistantly provided on the outer side of the constraint threaded cylinder 3. Each of the two mounting shells 1 has a second mounting cavity 15 at one corresponding end. The second mounting cavity 15 is rectangular, and a sealing block 16 is engaged inside each of the two corresponding second mounting cavities 15. When the two mounting shells 1 are brought together, they compress the sealing block 16. The constraint threaded cylinder 3 is then threaded onto the outer side of the two mounting shells 1 to lock them in place. First, the speaker channel guide structure is placed inside the two mounting shells 1, and then the two mounting shells 1 are brought together using the constraint threaded cylinder 3. Next, the in-ear capsule structure is installed at one end of the speaker channel guide structure. Finally, the speaker sound-producing structure is installed at the end of the speaker channel guide structure furthest from the in-ear capsule structure, allowing for rapid assembly of the entire speaker structure. The two constraint threaded cylinders 3 and a mounting block 17 lock the mounting shells 1 in place, simplifying the assembly process and improving assembly efficiency.

The limiting ring 11, the connecting block 14 and the compression ring 12 form a snap-fit ​​cavity. The first connecting ring 9 is set inside the snap-fit ​​cavity. The limiting ring 11 and the compression ring 12 compress the first connecting ring 9 to fix the connecting block 14 on the first connecting ring 9 for use. One end of the compression cylinder 4 also compresses one side of the compression ring 12 to help constrain the compression ring 12. The compression ring 12 has an adapter cavity 13 on one side corresponding to the first connecting ring 9. The second connecting ring 10 is fixedly installed on the first connecting ring 9 at the position corresponding to the adapter cavity 13.

[0024] The working principle of this utility model:

[0025] In use, first, the speaker channel guide structure is placed inside the two mounting shells 1. The two mounting shells 1 are then brought together by the constraint threaded cylinder 3. At this time, the in-ear capsule structure is installed at one end of the speaker channel guide structure. Finally, the speaker sound-producing structure is installed at the end of the speaker channel guide structure away from the in-ear capsule structure to quickly assemble the entire speaker structure. The mounting shells 1 are locked by the two constraint threaded cylinders 3 and a mounting block 17, which simplifies the assembly steps and improves assembly efficiency. When the two mounting shells 1 are brought together, they press against the sealing block 16. The mounting shells 1 are then locked by the constraint threaded cylinder 3 threadedly connected to the outside of the two mounting shells 1. The sound is transmitted from the speaker tube 8 to the inside of the in-ear capsule structure. The limiting ring 11 and the compression ring 12 compress the first connecting ring 9 to fix the connecting block 14 on the first connecting ring 9 for use. One end of the compression cylinder 4 also compresses one side of the compression ring 12 to assist in constraining the compression ring 12. The sound-producing speaker 19 is installed by the mounting block 17 and the mounting cylinder 18.
