Description

Technical Field

[0001] This disclosure relates to the technical field of headphones, and in particular to a rotating headphone connection structure and headphones. Background Technology

[0002] With the widespread adoption of personal audio devices, headphones have become increasingly popular due to their comfortable fit and high soundstage fidelity. Current headphones typically utilize a hinge structure between the earcups and headband to allow for rotation or flipping at a certain angle, adapting to different head shapes and facilitating storage.

[0003] However, these types of rotating structures generally suffer from the following drawbacks:

[0004] Traditional hinges often use a metal shaft with a plastic or metal bushing. Due to structural interference, the earcup can typically only rotate within a limited angle of 90° to 180°, making it difficult to meet users' needs in different usage scenarios, such as the requirement for 360° free rotation of the earcup when listening with one ear. Furthermore, most headphone rotating connection structures on the market use metal materials for the rotating parts and ear straps. However, repeated rotation and friction between metal materials can easily lead to wear and tear on the parts, and the repeated friction can also generate metal debris, thus affecting the overall lifespan of the headphones and the user experience. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a rotating headphone connection structure and headphones with a multi-angle rotating shell and reduced resistance of the rotating parts.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A rotating headphone connection structure includes an arm, a first ear shell, and a second ear shell, wherein the first ear shell is connected to a first end of the arm and the second ear shell is connected to a second end of the arm.

[0008] The rotating earphone connection structure further includes a rotating component and a connecting mounting plate. The rotating component protrudes from the second end of the support arm, and the connecting mounting plate is mounted on the outer peripheral wall of the second ear shell. The connecting mounting plate is provided with a rotating part, which protrudes from the end face of the connecting mounting plate and has a rotating opening. The first end of the rotating component is fixedly connected to the second end of the support arm, and the second end of the rotating component passes through the rotating opening and is rotatably connected to the rotating part. A silicone layer is provided on the surface of the rotating component, and the silicone layer slides on the surface of the rotating part.

[0009] In one embodiment, the rotating member has a rotating groove, which is disposed along the outer peripheral wall of the rotating member and communicates with the rotating opening.

[0010] In one embodiment, the end face of the connecting mounting plate is provided with a first fixing part and a second fixing part, the first end of the rotating part is connected to the first fixing part, and the second end of the rotating part is connected to the second fixing part; the first fixing part has a first connecting cavity, the second fixing part has a second connecting cavity, the first connecting post of the second ear shell is connected to the first fixing part through the first connecting cavity, and the second connecting post of the second ear shell is connected to the second fixing part through the second connecting cavity.

[0011] In one embodiment, the connecting mounting plate is provided with a limiting portion, which is located above the rotating part. The limiting portion has a limiting opening, and the rotating member passes through the limiting opening and the rotating opening in sequence to be rotatably connected to the rotating part. It can be understood that...

[0012] In one embodiment, the silicone layer covers the outer peripheral wall of the rotating member and extends to the end face of the rotating member, and the silicone layer forms a continuous annular damping surface.

[0013] A pair of headphones includes the rotating headphone connection structure described in any of the above embodiments.

[0014] Compared with the prior art, this disclosure has at least the following advantages:

[0015] The first earpiece is connected to the first end of the support arm, and the second earpiece is connected to the second end of the support arm, thus connecting the first and second earpieces together. A rotating component protrudes from the second end of the second support arm, and a connecting mounting plate is mounted on the outer peripheral wall of the second earpiece. A rotating part is provided on the connecting mounting plate, protruding from the end face of the connecting mounting plate and located below the rotating part. The first section of the rotating component is fixedly connected to the second end of the support arm, and the second end of the rotating component passes through a rotating opening and connects to the rotating part. This allows the second earpiece to rotate at multiple angles relative to the support arm through the rotational relationship between the rotating component and the rotating part. The rotating component forms a complete circular axis within the rotating opening, achieving continuous, interference-free 360° rotation of the second earpiece relative to the support arm, meeting the requirements of mono-ear monitoring scenarios. Meanwhile, a silicone layer is provided on the surface of the rotating part, and the silicone layer rotates on the surface of the rotating part, so that the silicone layer acts as an elastic damping medium. The friction between the silicone layer and the rotating part is avoided by the elastic damping medium, which can easily cause wear between parts due to repeated rotational friction. At the same time, it avoids the generation of metal chips caused by repeated friction between metal materials, which significantly reduces the generation of wear debris and extends the service life.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0026] like Figures 1 to 4 As shown, a rotating headphone connection structure 10 of one embodiment includes a support arm 100, a first ear shell 200 and a second ear shell 300. The first ear shell 200 is connected to a first end of the support arm 100, and the second ear shell 300 is connected to a second end of the support arm 100.

[0027] The rotating earphone connection structure 10 further includes a rotating component 400 and a connecting mounting plate 500. The rotating component 400 protrudes from the second end of the support arm 100, and the connecting mounting plate 500 is mounted on the outer peripheral wall of the second ear shell 300. The connecting mounting plate 500 is provided with a rotating part 510, which protrudes from the end face of the connecting mounting plate 500. The rotating part 510 has a rotating opening 5110. The first end of the rotating component 400 is fixedly connected to the second end of the support arm 100, and the second end of the rotating component 400 passes through the rotating opening 5110 and is rotatably connected to the rotating part 510. A silicone layer 410 is provided on the surface of the rotating component 400, and the silicone layer 410 slides on the surface of the rotating part 510.

[0028] In this embodiment, the first ear shell 200 is connected to the first end of the support arm 100, and the second ear shell 300 is connected to the second end of the support arm 100, thereby connecting the first ear shell 200 and the second ear shell 300 together. Meanwhile, a rotating member 400 protrudes from the second end of the second support arm 100, and a connecting mounting plate 500 is mounted on the outer peripheral wall of the second ear shell 300. A rotating part 510 is provided on the connecting mounting plate 500, and the rotating part 510 protrudes from the end face of the connecting mounting plate 500 and is located at the [missing information - likely a location or location]. Below; simultaneously, the first segment of the rotating component 400 is fixedly connected to the second end of the support arm 100, and the second end of the rotating component 400 passes through the rotation port 5110 and is connected to the rotating part 510. This allows the second ear shell 300 to rotate at multiple angles relative to the support arm 100 through the rotation relationship between the rotating component 400 and the rotating part 510. The rotating component 400 forms a complete circumferential axis within the rotation port 5110, achieving 360° continuous and interference-free rotation of the ear shell relative to the support arm 100, meeting the needs of multiple usage scenarios such as single-ear monitoring and neckband storage. Meanwhile, a silicone layer 410 is provided on the surface of the rotating component 400, and the silicone layer 410 rotates on the surface of the rotating part 510. This allows the silicone layer 410 to act as an elastic damping medium, rubbing against the rotating part 510. This avoids the wear between parts caused by repeated rotational friction, and also avoids the generation of metal shavings caused by repeated friction between metal materials, significantly reducing wear debris and extending service life. It should be noted that the silicone layer 410 refers to the surface of the rotating component 400 being covered with a silicone damping material, thereby forming a silicone layer 410 on the surface of the rotating component 400. The silicone damping material is existing technology and will not be described in detail here.

[0029] Combination Figure 1 and Figure 2As shown, in one embodiment, the rotating member 400 has a rotating groove 420, which is disposed along the outer peripheral wall of the rotating member 400 and communicates with the rotating opening 5110. It can be understood that by providing a rotating groove 420 along the outer peripheral wall of the rotating member 400, specifically, by having a ring-shaped structure that surrounds the rotating member 400 circumferentially, the outer peripheral wall of the rotating member 400 forms a concave-convex structure. The groove width of the rotating groove 420 is adapted to the thickness of the inner wall of the rotating opening 5110. When the second end of the rotating member 400 passes through the rotating opening 5110, the rotating part 510 has a limiting protrusion on the inner wall of the rotating opening 5110 that cooperates with the rotating groove 420. The limiting protrusion extends circumferentially along the rotating opening 5110 and is embedded in the rotating groove 420 and slidably connected to the inner wall of the rotating groove 420. By setting a mating structure between the rotating groove 420 and the limiting protrusion, the relative rotation of the rotating component 400 and the rotating part 510 can be axially limited. During the rotation of the second ear shell 300 relative to the support arm 100, the limiting protrusion is always engaged in the rotating groove 420, which can effectively prevent the rotating component 400 from moving along its axial direction and prevent the rotating component 400 from disengaging from the rotating opening 5110, thus ensuring the stability and reliability of the rotating connection.

[0030] Combination Figure 1 and Figure 2As shown, in one embodiment, the end face of the connecting mounting plate 500 is provided with a first fixing part 520 and a second fixing part 530. The first end of the rotating part 510 is connected to the first fixing part 520, and the second end of the rotating part 510 is connected to the second fixing part 530. The first fixing part 520 has a first connecting cavity 5210, and the second fixing part 530 has a second connecting cavity 5310. The first connecting post 310 protruding from the second ear shell 300 is connected to the first fixing part 520 through the first connecting cavity 5210, and the second connecting post 320 protruding from the second ear shell 300 is connected to the second fixing part 530 through the second connecting cavity 5310. It is understood that a first fixing part 520 and a second fixing part 530 are protruding from the end face of the connecting mounting plate 500, and a first connecting cavity 5210 is opened in the first connecting part. The first connecting post 310 protruding from the second ear shell 300 is inserted into the first connecting cavity 5210, thereby fixing the first connecting post 310 to the first fixing part 520. The second connecting post 320 protruding from the second ear shell 300 is inserted into the second connecting cavity 5310, thereby fixing the second connecting post 320 to the second fixing part 530. Furthermore, by fixing the first connecting post 310 and the second connecting post 320 to the first fixing part 520 and the second fixing part 530 respectively, the connecting mounting plate 500 can be stably installed on the end face of the second ear shell 300.

[0031] Combination Figure 1 and Figure 2 As shown, the connecting mounting plate 500 further includes a limiting part 540, which is positioned above the rotating part 510. The limiting part 540 has a limiting opening, through which the rotating member 400 sequentially passes to be rotatably connected to the rotating part 510. It can be understood that when the rotating member 400 sequentially passes through the limiting opening and the rotating opening 5110, the limiting part 540 forms a radial constraint on the upper part of the rotating member 400 through the limiting opening, while the rotating part 510 forms a radial constraint on the lower part of the rotating member 400 through the rotating opening 5110. This double-limiting structure effectively restricts the radial sway of the rotating member 400 during rotation, ensuring that the rotating member 400 maintains a stable axial position, significantly improving the stability and accuracy of the second ear shell 300 during rotation. Simultaneously, the inner wall of the limiting opening also contacts the silicone layer 410 on the surface of the rotating member 400, forming sliding friction during rotation. This not only further enhances the damping effect during rotation, making the rotation operation more responsive, but also reduces the rigid impact between the limiting part 540 and the rotating part 400 through the elastic buffering effect of the silicone layer 410, thus reducing the wear of both.

[0032] Combination Figure 1 and Figure 2 As shown, in one embodiment, the silicone layer 410 covers the outer peripheral wall of the rotating member 400 and extends to the end face of the rotating member 400, forming a continuous annular damping surface. The interference fit between the annular damping surface and the inner peripheral wall of the rotating opening 5110 is 0.1mm to 0.3mm. It can be understood that by completely covering the outer peripheral wall and end face of the rotating member 400, the silicone layer 410 forms an uninterrupted annular damping surface, ensuring that the contact area between the rotating member 400 and the rotating part 510 forms a complete annular friction surface, rather than localized contact. This continuous covering structure ensures the uniformity of the damping force distribution during rotation, avoiding rotational jamming or loosening caused by uneven local friction, and making the rotation of the second ear shell 300 smoother and more fluid. Furthermore, an interference fit of 0.1mm to 0.3mm is provided between the annular damping surface and the inner peripheral wall of the rotating port 5110. When the rotating component 400 passes through the rotating port 5110, the silicone layer 410 undergoes appropriate elastic deformation due to the interference fit, thereby forming a continuous and stable contact pressure on the inner peripheral wall of the rotating port 5110. This pressure ensures sufficient damping effect, providing clear tactile feedback during rotation, while preventing a surge in rotational resistance due to excessive interference fit, thus affecting the user's adjustment experience.

[0033] Combination Figure 2 and Figure 3 As shown, in one embodiment, the rotating headphone connection structure 10 further includes a connecting fastener 600. The support arm 100 has a mounting opening 110 on the side near the second earcup 300. The connecting fastener 600 is installed in the mounting opening 110. The first end of the rotating member 400 is welded to the connecting fastener 600, and the second end of the rotating member 400 passes through the mounting opening 110 and extends to the rotating opening 5110, rotatably connecting to the rotating part 510. It can be understood that the first end of the rotating member 400 is connected to the connecting fastener 600 by welding. This connection method allows the two to form a rigid whole, significantly improving the connection strength. Compared to simple plug-in or threaded connections, welding can effectively prevent the rotating member 400 from loosening or falling off during long-term rotational stress, ensuring the reliability of the connection between the rotating member 400 and the support arm 100. The second end of the rotating component 400 passes through the mounting port 110 and extends to the rotation port 5110, where it is rotatably connected to the rotating part 510. The mounting port 110 provides initial radial restraint to the extension of the rotating component 400, forming a double constraint with the rotation port 5110 of the rotating part 510, further reducing the radial wobble of the rotating component 400 during rotation. Simultaneously, the connecting fastener 600, through its tight fit with the mounting port 110, distributes the rotational torque and axial force borne by the rotating component 400 to the support arm 100, preventing excessive local stress and deformation of the support arm 100, and enhancing the load-bearing capacity of the entire rotary connection structure.

[0034] Combination Figure 1 and Figure 2 As shown, the connecting mounting plate 500 is further detachably connected to the end face of the second ear shell 300. It is understood that this detachable connection facilitates the assembly, maintenance, and replacement of the connecting mounting plate 500 and the second ear shell 300. When the connecting mounting plate 500 or the second ear shell 300 is damaged, it is not necessary to replace the entire earphone; only the damaged part needs to be removed for repair or replacement, greatly reducing maintenance costs.

[0035] like Figure 2 As shown, in one embodiment, a limiting boss 430 is provided at the end of the rotating member 400 away from the second ear shell 300. The limiting boss 430 rotatably abuts against one side of the rotating part 510. The limiting boss 430 protrudes outward along the outer peripheral wall of the rotating member 400, and its diameter is larger than the inner diameter of the rotating opening 5110. When the rotating member 400 passes through the rotating opening 5110, the limiting boss 430 is exactly located on the side of the rotating part 510 away from the second ear shell 300. During the rotation of the second ear shell 300 relative to the support arm 100, the limiting boss 430 always maintains abutment with the side of the rotating part 510. This abutment relationship can play an axial limiting role for the rotating member 400, effectively preventing the rotating member 400 from moving away from the second ear shell 300. The mating structure of the rotating groove 420 and the limiting boss 430 constrains the axial movement of the rotating part 400 from two different directions, further preventing the rotating part 400 from detaching from the rotating port 5110 and significantly improving the stability of the rotating connection.

[0036] like Figure 4 As shown, this application also includes a headset, comprising the rotating headphone connection structure 10 described in any of the above embodiments.

[0037] Compared with the prior art, this disclosure has at least the following advantages:

[0038] The first ear shell 200 is connected to the first end of the support arm 100, and the second ear shell 300 is connected to the second end of the support arm 100, thereby connecting the first ear shell 200 and the second ear shell 300 together; at the same time, the rotating member 400 protrudes from the second end of the second support arm 100, and the connecting mounting plate 500 is installed on the outer peripheral wall of the second ear shell 300. The connecting mounting plate 500 is provided with a rotating part 510, and the rotating part 510 protrudes from the end face of the connecting mounting plate 500 and is located below the rotating part 510. Meanwhile, the first segment of the rotating component 400 is fixedly connected to the second end of the support arm 100, and the second end of the rotating component 400 passes through the rotating opening 5110 and is connected to the rotating part 510. This allows the second ear shell 300 to rotate at multiple angles relative to the support arm 100 through the rotation relationship between the rotating component 400 and the rotating part 510. The rotating component 400 forms a complete circumferential axis within the rotating opening 5110, enabling the ear shell to rotate continuously and without interference at 360° relative to the support arm 100, meeting the needs of various usage scenarios such as single-ear monitoring and neckband storage. Simultaneously, a silicone layer 410 is provided on the surface of the rotating component 400, and the silicone layer 410 rotates on the surface of the rotating part 510. This allows the silicone layer 410 to act as an elastic damping medium, rubbing against the rotating part 510. This avoids the wear between parts caused by repeated rotational friction, and also prevents the generation of metal shavings due to repeated friction between metal materials, significantly reducing wear debris and extending service life.

[0039] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
