[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: like Figure 1 As shown, this embodiment of the invention provides a headphone with detachable ear tips, including a headphone frame 1. A protective strip 2 is provided on the upper inner surface of the headphone frame 1. The protective strip 2 is made of flexible material and serves to protect the head and provide comfort. The bottom two sides of the headphone frame 1 are connected to telescopic strips 3 by locking mechanisms 9. The two telescopic strips 3 can move in and out of the headphone frame 1 and are locked by locking mechanisms 9.

[0021] In the above structure, the two telescopic strips 3 extend and retract inside the headphone frame 1 and are locked by the locking mechanism 9, thereby adapting to different head shapes.

[0022] Speakers 4 are fixedly connected to the bottom of both telescopic strips 3. A housing 5 is provided on one side of the speaker 4. A limiting ring 7 is fixedly sleeved on the outer wall of the housing 5. An earphone cover 6 is threadedly connected to the outer side of the housing 5. Limiting mechanisms 8 are provided on the upper and lower sides of the housing 5. When the earphone cover 6 is fully threaded into the housing 5, the earphone cover 6 abuts against the limiting ring 7, and the limiting end of the limiting mechanism 8 limits and locks the earphone cover 6. A diaphragm 10 is provided inside the earphone cover 6 to protect and comfort the ears.

[0023] With the above structure, when the earphone cover 6 is fully threaded into the outer shell 5, the limiting end of the limiting mechanism 8 limits and locks the earphone cover 6 to prevent the threads from loosening.

[0024] Example 2: Based on Example 1, combined with Figure 2 , Figure 3 and Figure 4Specifically, the limiting mechanism 8 includes limiting frames 81 embedded on the upper and lower sides of the outer shell 5. A guide rod 83 slides through one side of the limiting frame 81. A pressing block 82 is fixedly connected to the upper end of the guide rod 83. A connecting plate 84 is fixedly connected to the bottom end of the guide rod 83. A clip head 87 is fixedly connected to the upper surface of the other side of the connecting plate 84. The upper end of the clip head 87 is inserted into the slot 61 opened inside the earphone cover 6.

[0025] Two first springs 85 are fixedly connected to the inner bottom wall of the limiting frame 81. The upper end of the first spring 85 is fixedly connected to the connecting plate 84, which plays a rebound role. A telescopic rod 86 is fixedly connected to the middle of the inner bottom wall of the limiting frame 81. The upper end of the telescopic rod 86 is fixedly connected to the connecting plate 84, which plays a limiting and guiding role.

[0026] In the above structure, when the earphone cover 6 is fully threaded into the outer shell 5, the limiting end of the limiting mechanism 8 limits and locks the earphone cover 6. Specifically, manually pressing the pressing block 82 causes the guide rod 83, connecting plate 84 and locking head 87 to retract. When the earphone cover 6 is fully threaded into the outer shell 5, the locking head 87 will be aligned with the slot 61 by default. Then, by releasing the pressing block 82, under the action of the first spring 85, the locking head 87 will be locked into the slot 61, thus preventing the threads from loosening.

[0027] Secondly, combining Figure 5 , Figure 6 and Figure 7 Specifically, the locking mechanism 9 includes a locking frame 901 fixedly connected to the outer surface of the headphone frame 1. The locking frame 901 has a movable worm gear 910 and a worm wheel 911 rotatably connected inside the locking frame 901. A connecting shaft 912 is fixedly connected to the middle of the worm wheel 911. The outer end of the connecting shaft 912 extends into the interior of the headphone frame 1 and is fixedly connected to a positioning gear 913. The side of the positioning gear 913 meshes with the teeth 31 fixed to the surface of the telescopic strip 3.

[0028] A sliding rod 903 slides through the bottom of the locking frame 901. A pressing head 902 is fixedly connected to the bottom of the sliding rod 903. A first rack 904 is fixedly connected to the upper end of the sliding rod 903. A connecting gear 906 is meshed with the left side of the first rack 904. A second rack 907 is meshed with the left side of the connecting gear 906. A slide 908 is fixedly connected to the upper end of the second rack 907. Slider 914s are fixedly connected to both sides of the slide 908. Slide grooves 915 are provided on both inner walls of the locking frame 901. The slider 914 is slidably connected to the slide grooves 915 to limit the sliding. A rotating shaft 909 is rotatably connected to the middle of the slide 908. A worm gear 910 is fixedly sleeved on the outer wall of the rotating shaft 909.

[0029] A second spring 905 is fixedly connected to the bottom of the first rack 904. The bottom of the second spring 905 is fixedly connected to the inner wall of the locking frame 901, which serves as a springback mechanism.

[0030] A counterweight 916 is provided on the outer side of the first rack 904 to serve as a counterweight.

[0031] In the above structure, the two telescopic strips 3 move telescopically inside the headphone frame 1 and are locked by the locking mechanism 9, thus adapting to different head shapes. Specifically, manually pressing the pressing head 902 moves it upward, and under the connection of the first rack 904, the connecting gear 906, and the second rack 907, it drives the slide 908 downward, causing the worm gear 910 and the worm wheel 911 to separate. This allows the telescopic strips 3 to move telescopically inside the headphone frame 1 for adjustment. After adjustment, releasing the pressing head 902 causes the worm gear 910 and the worm wheel 911 to re-engage under the action of the second spring 905 and the counterweight 916, achieving self-locking and preventing the telescopic strips 3 from moving on their own.

[0032] Working principle: When using this detachable earphone, the user manually squeezes the pressing head 902 to move it upward according to the size of the user's head. At this time, the telescopic strip 3 can be moved inside the headphone frame 1 to adjust the size. After adjustment, the pressing head 902 is released, and the telescopic strip 3 will lock itself inside the headphone frame 1, preventing the telescopic strip 3 from moving on its own. Secondly, when it is necessary to remove the earphone cover 6, manually squeeze the pressing block 82 to disengage the locking head 87 from the slot 61. At this time, the earphone cover 6 can be unscrewed for cleaning or other treatment. When reinstalling, manually squeeze the pressing block 82. When the earphone cover 6 is fully threaded into the outer shell 5, the earphone cover 6 abuts against the limiting ring 7. At this time, release the pressing block 82, and the locking head 87 will snap into the slot 61 to complete the locking and prevent the threads from loosening.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
