[0039] This utility model discloses a headset to solve the technical problem that users cannot accurately judge whether the headset shell has been rotated to a safe angle that allows for disassembly, which can easily lead to blind operation by users and cause structural damage.

[0040] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 9 This utility model provides a type of over-ear headphone, including a headband 1 and a headphone shell 3 for accommodating the headphone body. The headphone shell 3 includes a shell body 301 and a cover plate 302 detachably fitted onto the shell body 301. Mounting brackets 2 are provided at opposite ends of the headband 1. The headphone shell 3 is rotatably connected to the mounting brackets 2. A rotating shaft 5 is provided on the mounting bracket 2. The shell body 301 has a rotating hole. The rotating shaft 5 is rotatably connected to the rotating hole so that the shell body 301 can be driven to rotate relative to the mounting bracket 2. An elastic engaging part 6 is provided inside the shell body 301. The rotating shaft 5 has a first guide groove 501 and a second guide groove 502 arranged sequentially along its circumference, which can engage with the elastic engaging part 6.

[0042] In this embodiment of the headphones, when the user needs to remove the cover plate 302 on the headphone shell 3 from the shell body 301, they only need to rotate the headphone shell 3 relative to the mounting bracket 2 to a preset angle, so that the elastic engaging part 6 leaves the first guide groove 501 and engages in the second guide groove 502, thus putting the headphone shell 3 in a detachable state. At this time, the user can disassemble the headphone shell 3. Through the above design, during the rotation of the headphone shell 3, the elastic engaging part 6 will move from the first guide groove 501 into the second guide groove 502. The elastic engaging part 6 will generate a sudden torque change during the process of switching to engage with different guide grooves, thereby providing the user with a clear tactile feeling, so that the user can accurately judge that the headphone shell 3 has entered the detachable state, effectively avoiding structural damage to the headphones caused by user misoperation.

[0043] Specifically, the earphone housing 3 has a working state and a detachable state;

[0044] When the elastic engaging part 6 engages with the first guide slot 501, the headset is in use.

[0045] When the earphone shell 3 rotates relative to the mounting bracket 2 by a preset angle in a preset direction, the elastic engaging part 6 disengages from the first guide groove 501 and engages within the second guide groove 502. The earphone shell 3 is then in a detachable state. Specifically, after the earphone shell 3 rotates by the preset angle, there is sufficient space between the earphone shell 3 and the mounting bracket 2 for the user to disassemble the earphone shell 3. The preset direction can be either clockwise or counterclockwise, and can be selected according to actual design requirements.

[0046] Furthermore, in this embodiment, the elastic engaging part 6 is specifically a spring piece that is bent to form an engaging protrusion 601, wherein the spring piece can be installed inside the housing body 301 by means of screw fixing or the like.

[0047] It should be noted that when the engaging protrusion 601 engages with the first guide slot 501, the headset is in use.

[0048] When the earphone shell 3 rotates at a preset angle relative to the mounting bracket 2, the engaging protrusion 601 leaves the first guide groove 501 and engages in the second guide groove 502. At this time, the spring will undergo a certain elastic deformation, thereby providing the user with a certain tactile sensation so that the user can determine that the earphone shell 3 is in a detachable state.

[0049] Specifically, the spring in this embodiment is a metal spring.

[0050] It should be noted that, through the above design, when the metal spring contacts the first guide slot 501 or the second guide slot 502, the engaging protrusion 601 of the metal spring will collide with the slot wall and generate a certain sound, so that the user can judge from the sound that the headphone shell 3 is in a detachable state.

[0051] In addition, the engaging protrusion 601 in this embodiment is an arc-shaped protrusion.

[0052] Furthermore, in this embodiment, the housing body 301 is provided with an elastic hook 4, and the cover plate 302 is provided with a fixing hook 7 that cooperates with the elastic hook 4;

[0053] The elastic hook 4 has a trigger portion 402 exposed outside the housing body 301.

[0054] It should be noted that when the cover plate 302 is closed on the housing body 301, the elastic hook 4 and the fixed hook 7 engage with each other to fix the cover plate 302 on the housing body 301;

[0055] When the earphone housing 3 is in a detachable state, the trigger part 402 is driven to move inward toward the interior of the housing body 301 so that the elastic hook 4 separates from the fixed hook 7.

[0056] Specifically, the elastic hook 4 in this embodiment includes a hook part 401, an elastic element 403, and the trigger part 402;

[0057] The top of the housing body 301 has a movable through hole. The trigger part 402 is movably inserted into the movable through hole and connected to the hook part 401. The end of the trigger part 402 away from the hook part 401 is exposed outside the housing body 301. One end of the elastic member 403 is connected to the hook part 401, and the other end of the elastic member 403 is connected to the interior of the housing body 301. The elastic member 403 tends to engage the hook part 401 with the fixed hook 7.

[0058] It should be noted that, through the above design, when the trigger part 402 is not pressed, the elastic element 403 continuously provides elastic force to the hook part 401, so that the hook part 401 is continuously and stably engaged with the fixed hook 7, thereby ensuring the connection stability between the cover plate 302 and the housing body. Specifically, the elastic element 403 is preferably a spring.

[0059] In addition, when the trigger part 402 is pressed, the pressing force is greater than the elastic force of the elastic member 403, and the hook part 401 and the fixed hook 7 are displaced relative to each other to disengage from the fixed hook 7. At this time, the user can remove the cover plate 302 from the housing body 301.

[0060] Furthermore, in this embodiment, when the headphones are in use, the distance between the end of the trigger part 402 away from the hook part 401 and the mounting bracket 2 is in the range of 0~0.3mm.

[0061] It should be noted that by limiting the distance mentioned above, the user is prevented from accidentally triggering the trigger unit 402 when the headphones are in use.

[0062] Furthermore, the preset angle in this embodiment ranges from 40° to 50°.

[0063] It should be noted that, in this embodiment, the earphone shell 3 is preferably rotated 45° relative to the mounting bracket 2 to enter a detachable state. At this time, the elastic locking part 6 enters the second guide slot 502 from the first guide slot 501.

[0064] Furthermore, in this embodiment, the first guide slot 501 and the second guide slot 502 are V-shaped guide slots.

[0065] It should be noted that in this embodiment, the first guide slot 501 and the second guide slot 502 have the same shape and structure. The opposite side walls of the first guide slot 501 and the second guide slot 502 form an included angle of 120°, and the connection between the side walls and the outer wall of the rotating shaft 5 is designed with rounded corners so that the elastic engaging part 6 can switch positions more easily between the first guide slot 501 and the second guide slot 502.

[0066] Furthermore, in order to better improve the rotational damping of the earphone shell 3, a damping pad is provided on the inner wall of the rotating hole in this embodiment;

[0067] The damping pad abuts against the rotating shaft 5.

[0068] Furthermore, in this embodiment, the damping pad is preferably a silicone pad or a rubber pad with a compression range of 0.3mm to 0.5mm.

[0069] The above provides a detailed description of the over-ear headphones provided by this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
