[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1

[0025] In this embodiment, if Figure 1-Figure 6 As shown, an adjustable headphone comprises two ear shells 1, a headband 2 is arranged between the two ear shells 1, and the distance between the ear shells 1 is adjusted. A slide groove 3 is arranged inside the headband 2, and an adjustment mechanism is also included. The adjustment mechanism is arranged inside the slide groove 3, and is used to adapt to the head circumference of different users. Before the adjustable headphone starts to be used, it is first checked whether the headphone can be used normally. The user then places the headband 2 on the head and adjusts the adjustment mechanism so that the ear accommodating cavity can correspond to the ear, so that the headphone enters a ready-to-use state;

[0026] Among them Figure 3 and Figure 4 The adjusting mechanism comprises a fixed block fixedly mounted on the top of the headband 2, and a turning knob 4 is rotatably connected to the upper end of the fixed block. When the turning knob 4 is rotated, the rotating shaft 5 is rotated, thereby driving the gear 6 to rotate. Since the toothed belt 7 is meshed with the gear 6 for transmission, the toothed belts 7 on both sides can approach or move away from each other along the direction of the slide slot 3, thereby adjusting the position of the ear shell 1. The lower end of the turning knob 4 is fixedly connected to the rotating shaft 5, one end of the rotating shaft 5 extends into the slide slot 3 and is connected to the gear 6, and both sides of the gear 6 are meshed and connected with the toothed belt 7, which is slidably connected to the slide slot 3, and one end of the toothed belt 7 is connected to the top of the ear shell 1. The structure is simple and easy to use, and it is convenient to quickly adjust the position of the two ear shells 1, so as to prevent the ears from being squeezed due to discomfort in wearing, and enhance the comfort of the adjustable headphone during use. The headphone can be fixed on the user's head, and the user does not need to manually support the headphone all the time, and it is also convenient for the user to take off the headphone.

[0027] Among them Figure 5 and Figure 6 As shown, the ear shell 1 includes a shell 8 and an ear shell bracket 9. The ear shell bracket 9 is connected to the shell 8 by bolts, which is convenient for cleaning and disassembly, and convenient for maintenance. An earmuff 10 is arranged on one side of the ear shell bracket 9. An ear accommodating cavity is formed between the earmuff 10 and the ear shell bracket 9. A speaker 11 is arranged inside the ear accommodating cavity. The speaker 11 is arranged inside the ear accommodating cavity, so that the speaker 11 is closer to the ear, thereby improving the sound cavity effect of the ear accommodating cavity. A panel 12 is arranged on one side of the speaker 11. The panel 12 is fixedly connected to the ear shell bracket 9. A plurality of sound outlet holes 13 are opened on the surface of the panel 12. The sound of the speaker 11 is transmitted to the user's ear through the sound outlet holes 13 on the surface of the panel 12, thereby increasing the broadcasting effect of the earphone.

[0028] Among them Figure 4 As shown, a limit block 16 is provided on one side of the toothed belt 7. The function of the limit block 16 is to limit the sliding distance of the toothed belt 7 to prevent the toothed belt 7 from being unable to return to the initial position, thereby affecting the next use;

[0029] Among them Figure 1 and Figure 2 As shown, the outer side of the earmuff 10 is provided with a soundproof cover, which can prevent the earphone from leaking sound during use and improve the privacy of the user;

[0030] Among them Figure 1 As shown, the earmuff 10 is made of elastic rubber material to increase the comfort of the user;

[0031] Example 2

[0032] The difference from Example 1 is that Figure 1 As shown, a connecting rod 14 is provided above the headband 2, and both ends of the connecting rod 14 are fixedly connected to the ear shell 1. The connecting rod 14 limits the length of the headband 2 and makes it convenient for the user to carry the headset and move it around.

[0033] Among them Figure 1 As shown, an anti-skid pad 15 is fixedly provided on the lower surface of the headband 2. The contact between the anti-skid pad 15 and the user's head can increase the friction effect, thereby preventing the earphone from falling off during use and causing damage to the earphone.

[0034] When in use, the user first places the headband 2 on the head and matches the ear accommodating cavity with the ear. When the size of the headband 2 does not match the user's head circumference, the user adjusts the position of the ear shell 1 by turning the knob 4 with one hand. After turning the knob 4, the shaft 5 drives the gear 6 to rotate, thereby driving the toothed belts 7 on both sides to approach or move away from each other along the direction of the slide groove 3. Since the toothed belts 7 are connected to the shell 8, the distance between the ear shells 1 can be adjusted to adapt to users with different head circumferences and enhance the practical effect.

[0035] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
