Preferably, rectangular openings are formed in the outer walls of the two sides of the earphone shell, and the two rectangular openings are communicated with the two sliding grooves respectively.

Preferably, the inner walls of the two rectangular openings are both connected with sliding blocks in a sliding mode.

Preferably, two sliding block top outer wall all sets up threaded hole, and the equal spiro union of inner wall of two threaded holes has fastening bolt.

Preferably, the two sliding blocks are respectively connected to the two mounting blocks through two fastening bolts.

Preferably, earphone shell bottom outer wall is provided with the spool, one side outer wall that earphone shell was kept away from to the sound pipe is provided with the filter screen.

The utility model has the advantages that:

1. this in-ear earphone through be provided with the thread bush in the rubber sleeve, through the screw thread of thread bush spiro union on the sliding tube, avoids the rubber sleeve to drop easily through the connection of this kind of screw thread formula, has solved the problem that current in-ear earphone dropped easily.

2. This in-ear earphone through set up the slide tube in earphone shell inside, drags the slide tube through the sliding block and removes, and then drives the rubber sleeve and remove, makes the sound pipe release the earwax in the rubber sleeve, has solved the problem of the frequent adhesion earwax of the rubber sleeve inner wall of current in-ear earphone.
