Description

Technical Field

[0001] This utility model relates to the technical field of headphone microphone rod angle adjustment structure, and in particular to a novel headphone microphone rod adjustment structure and a novel headphone. Background Technology

[0002] Headphones are typically equipped with a microphone boom. In order to accurately adjust the microphone to the vicinity of the user's mouth during use, and to maintain a stable position after adjustment, and to be stored away to reduce size when not in use, the microphone boom needs to be adjustable and able to maintain a stable angle.

[0003] Chinese patent CN219740587U discloses a microphone lever device for headphones with damping adjustment. This device uses an internal gear slot within the microphone lever connector. Damping and a tactile feedback are generated by the engagement of a protrusion on a limiting spring sleeved on a plug pin with the internal gear slot. While this structure achieves adjustment, it relies on gear engagement, resulting in a distinct tactile feedback rather than stepless adjustment. The feel is discontinuous, and the structure is relatively complex, with numerous parts, making assembly difficult.

[0004] Another solution, as shown in Chinese Patent Publication No. CN209250843U, is a slim headphone with a support structure. It uses a positioning block on a damping plate and a positioning groove on a damping cover plate to achieve the rotation and positioning of the microphone boom. This "protrusion-groove" positioning structure produces a noticeable jerking sensation during rotation, making smooth, stepless adjustment impossible.

[0005] Furthermore, Chinese patent CN216930278U discloses a rotatable headset, which achieves rotation and damping by using an elastic protrusion on the inner part to engage with an interference fit hole in the middle connecting part. This structure also relies on the interference fit between discrete protrusions and the hole walls, resulting in insufficient uniformity and continuity of damping, which affects the user experience.

[0006] Therefore, existing headphone microphone rod adjustment structures either suffer from uneven damping and poor stability, or are structurally and installation-intensive, or cannot simultaneously achieve stepless adjustment and stable angle maintenance. Thus, there is an urgent need for a novel headphone microphone rod adjustment structure that is simple in structure, provides uniform and stable damping, enables smooth stepless adjustment, and reliably maintains the angle.

[0012] Preferably, a pair of mutually cooperating limiting elements are provided between the first housing and the second housing; when the first housing and the second housing rotate relative to each other to a set angle, the limiting elements interfere with each other to limit the first housing from continuing to rotate.

[0022] This utility model provides a novel headphone microphone adjustment structure and a novel headphone, wherein the novel headphone microphone adjustment structure includes: The first housing 10 is provided with a microphone rod 11, a first connecting part 12, and a first annular damping structure 13 surrounding the first connecting part 12. The second housing 20 has a second connecting part 21 rotatably connected to the first connecting part 12, and a second annular damping structure 22 surrounding the second connecting part 21. When the first connecting part 12 and the second connecting part 21 are assembled, the first annular damping structure 13 and the second annular damping structure 22 are interference-fitted to provide damping force for the relative rotation between the first housing 10 and the second housing 20, so as to maintain the adjustment angle of the microphone rod 11.

[0023] In specific implementation, such as Figures 1-6 As shown, the novel headphone microphone adjustment structure includes: like Figure 2 As shown, the first housing 10 has a microphone rod 11, a first connecting part 12 and a first annular damping structure. The first connecting part 12 is located on the first side wall of the first housing 10 when worn, the microphone rod 11 is located on the second side wall, the first side wall and the second side wall are not parallel, and the first annular damping structure 13 is located on the first side wall of the first housing 10 and surrounds the first connecting part 12. The second housing 20 is provided with a second connecting part 21 rotatably connected to the first connecting part 12, and a second annular damping structure 22 surrounding the second connecting part 21; the rotatable connection structure includes, but is not limited to, shaft connection, snap-fit ​​bushing and other structures. During assembly, the first connecting part 12 and the second connecting part 21 are rotatably connected, allowing the first housing 10 to rotate relative to the second housing 20. After assembly, the first annular damping structure 13 and the second annular damping structure 22 are interference-fitted, resulting in uniform and continuous frictional resistance (i.e., damping force) on the 360° annular contact surface of the first housing 10. This large-area annular damping force can counteract the weight of the microphone pole 11 and slight external forces at any angle, achieving stepless, smooth adjustment and reliable angle maintenance. This eliminates the shifting and jerking sensations caused by gears or protrusions, improving the user experience.

[0024] The novel headphone microphone adjustment structure provided in this embodiment of the utility model achieves uniform distribution of damping force throughout the entire rotation range through the interference fit of the annular damping surface, providing users with a smooth, unobstructed, and precise stepless adjustment experience. It is also simple in structure and easy to assemble.

[0025] Furthermore, the first connecting portion 12 includes a plurality of lever arms 121 protruding from the side wall of the first housing 10 and a hook 122 provided at the end of the lever arm 121, and the plurality of lever arms 121 are arranged around the perimeter. The second connecting part 12 is a through hole; During assembly, the hook 122 passes through the through hole and engages with the edge of the through hole.

[0026] In specific implementation, such as Figure 5 , Figure 6 As shown, the first connecting portion 12 includes several elastic lever arms 121 protruding from the sidewall of the first housing 10 and hooks 122 disposed at the ends of the lever arms 121, and these lever arms 121 are arranged around the central axis; correspondingly, the second connecting portion 21 is a through hole (such as... Figure 5 As shown); during assembly, simply align the hook 122 of the first housing 10 with the through hole of the second housing 20 and press it in. After the hook 122 passes through the through hole, its elastic arm 121 rebounds, causing the hook 122 to engage with the edge of the through hole, thus quickly completing the assembly of the rotating shaft. This "snap-on" design requires no screws or additional shaft pins, resulting in high assembly efficiency and low cost.

[0027] Furthermore, the first annular damping structure 13 is a first annular protrusion; The second annular damping structure includes a first annular groove 221 and an annular damping element 222 disposed in the first annular groove 221; The first annular protrusion is disposed within the first annular groove 221, and the first annular protrusion is in interference contact with the annular damping member 222.

[0028] In specific implementation, such as Figure 2 As shown, the first annular damping structure 13 is a first annular protrusion protruding from the first housing 10, and the second annular damping structure 22 includes a first annular groove 221 and an annular damping element 222 embedded in the groove. The annular damping element 222 is, but is not limited to, made of an elastic material (such as rubber, silicone, polyurethane, or special rubber) with a high coefficient of friction and good wear resistance. After assembly, the first annular protrusion is pressed into the first annular groove 221 and continuously and interference-pressed against the side wall of the annular damping element 222. In this embodiment, the structure of the annular groove, annular protrusion, and annular damping element 222 cooperating utilizes the properties of the elastic material to provide a softer and more stable frictional force, improving the feel, while concentrating wear mainly on this replaceable damping element, protecting the plastic housing body and extending the service life of the overall structure.

[0029] Furthermore, a second annular groove 223 is provided on one side of the first annular groove 221; The first housing 10 has a second annular protrusion 14 at the part corresponding to the second annular groove 223; the groove width of the second annular groove 223 is adapted to the thickness of the second annular protrusion 14.

[0030] Furthermore, the outer wall of the second annular protrusion is a stepped structure 15; the stepped structure 15 is engaged with the slot of the second annular groove 223.

[0031] In specific implementation, such as Figure 2 , Figure 4 As shown, a second annular groove 223 communicating with the first annular groove 221 is provided on one side. A second annular protrusion 14 is provided on the first housing 10 at a position corresponding to the second annular groove 223. The groove width of the second annular groove 223 is precisely matched with the thickness of the second annular protrusion 14. The outer wall of the second annular protrusion 14 is designed as a stepped structure 15 (e.g., Figure 2 As shown, the stepped structure 15 can precisely engage with the slot of the second annular groove 223, forming an axial limit. This embodiment provides precise radial guidance and robust axial locking, effectively preventing the risk of wobbling or axial separation of the two housings during rotation, ensuring the stability and consistency of the damping fit, and making the entire adjustment structure more stable and reliable.

[0032] Furthermore, a pair of mutually cooperating limiting elements are provided between the first housing 10 and the second housing 20; when the first housing 10 and the second housing 20 rotate relative to each other to a set angle, the limiting elements interfere with each other to restrict the first housing 10 from continuing to rotate.

[0033] In specific implementation, such as Figure 4 As shown in Figure 5, the pair of mutually cooperating limiting elements include a limiting protrusion 16 and a limiting stop 23, which are respectively disposed in the first housing 10 and the second housing 20. The limiting protrusion 16 rotates with the first housing 10 and abuts against the limiting stop 23 on the second housing 20 when it rotates to a set angle (e.g., 180°), thereby limiting the rotation range of the first housing 10 and preventing the internal connecting wires from getting tangled or damaged due to excessive rotation.

[0034] Furthermore, the interference fit between the first annular damping structure 13 and the second annular damping structure 22 is 0.05-0.15 mm. In this embodiment, the interference fit between the first annular damping structure 13 and the second annular damping structure 22 is controlled between 0.05 mm and 0.15 mm. Within this range, sufficient damping force to maintain the angle is provided without causing adjustment difficulties or structural damage due to excessive interference fit. Preferably, the interference fit between the first annular damping structure 13 and the second annular damping structure 22 is 0.1 mm.

[0035] Furthermore, the first housing 10 and / or the second housing 20 are provided with an angle detection device for detecting the relative rotation angle between the first housing 10 and the second housing 20.

[0036] Furthermore, the angle detection device includes a magnetic element 17 fixed to the first housing 10 and a sensing element fixed to the second housing 20; when the first housing 10 and the second housing 20 rotate relative to each other, the sensing element determines the relative rotation angle between the first housing 10 and the second housing 20 by sensing the change in the magnetic field generated by the magnetic element 17.

[0037] In specific implementation, such as Figure 5 As shown, the first housing 10 is provided with a slot, and a magnetic element 17 (such as a magnet) is provided in the slot. A sensing element (such as a Hall sensor) is set on the second housing 20 as needed. When the user adjusts the microphone rod 11, the magnetic element 17 rotates synchronously with the first housing 10, and its magnetic field direction relative to the fixed Hall sensor changes. The Hall sensor detects this magnetic field change, converts it into an electrical signal, and sends it to the control circuit of the headset for subsequent function control.

[0038] This utility model also provides a novel earphone, which adopts the novel earphone microphone adjustment structure described above.

[0039] A novel earphone employs the microphone rod adjustment structure described above. Therefore, the novel earphone of this utility model embodiment has a series of advantages such as smooth stepless adjustment, stable angle maintenance, compact and durable structure, and is significantly superior to earphones using traditional adjustment structures in terms of call clarity, ease of use and product reliability.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
