[0022] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in

[0023] In this embodiment, one end of the positioning block 8 passes through the positioning opening and extends into the interior of the barrel 4, and is in contact with the outer side surface of the positioning ring 7. The inner side surface of the positioning ring 7 is in contact with the end of the barrel 4 away from the sound outlet pipe 2. The other end of the positioning block 8 extends to the outside and expands outward to form a positioning portion 6 with an arc structure. A positioning groove with an annular structure is provided on the inner wall surface of the earplug 3 opposite to the positioning portion 6, and the positioning portion 6 is inserted into the positioning groove.

[0024] In this embodiment, the end surface of the sound outlet cylinder 5 away from the Bluetooth headset body 1 is flush with the end surface of the barrel 4, avoiding unevenness that may cause impurities or dust to enter the interior of the sound outlet hole. After removing the earplug, the flush sound outlet net facilitates the removal of dust on the surface.

[0025] In this embodiment, clamping grooves are provided on the top and bottom surfaces of the positioning opening, and clamping blocks 9 protrude from the top and bottom surfaces of the positioning block 8. The clamping blocks 9 are inserted into the clamping grooves and are fixedly clamped with the clamping grooves. The installation and disassembly of the positioning block are facilitated by the clamping connection between the clamping block and the clamping groove.

[0026] In this embodiment, an external thread is provided on the outer wall surface of the sound outlet pipe 2, and an internal thread is provided on the inner wall surface of the barrel 4. The barrel 4 is threadedly connected to the external thread on the sound outlet pipe 2 through the internal thread. The disassembly is facilitated by the threaded connection, and the length of the sound outlet pipe can also be extended.

[0027] In this embodiment, the outer circumferential surface of the sound outlet cylinder 5 is in contact with the inner circumferential surface of the sound outlet hole, so that the sound outlet cylinder can be in full contact with the sound outlet hole, preventing external impurities from entering. The sound outlet cylinder is a sound outlet net in a cylindrical structure.

[0028] During use, the distance that the cylinder body and the earplug extend can be adjusted according to different users, so as to adapt to ear holes of different depths. When adjusting, the cylinder body can be directly rotated to move the cylinder body outward or inward along the thread on the sound outlet pipe. The rotation of the cylinder body drives the earplug, causing the earplug to rotate and extend or retract until the earplug can be in full contact with the ear hole when inserted into the ear hole, increasing the sound insulation effect.

[0029] Among them, after the earplug is unplugged, the positioning part can be pulled outward. The movement of the positioning part drives the positioning block, enabling the positioning block to disengage from the card slot. And after the blocking of the positioning block is removed, the cylinder body can be removed from the sound outlet pipe, and the sound outlet cylinder can be taken out along the opening of the cylinder body, facilitating its replacement. A new sound outlet cylinder can be put into the interior of the cylinder body again until it is inserted into the sound outlet hole. At this time, the positioning block can be inserted again to make the positioning block abut against the positioning ring, thereby positioning the positioning ring and the sound outlet cylinder to ensure the impurity interception effect;

[0030] After the positioning block is installed, the cylinder body can be screwed onto the sound outlet pipe again, and the earplug can be sleeved in the cylinder body again. After the earplug is sleeved, the positioning part can be inserted into the positioning slot of the ear hole, thereby positioning and fixing the ear hole.

[0031] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
