Description

Technical Field

[0001] This utility model relates to the technical field of headphone hinges, and more particularly to a headphone hinge structure and headphone. Background Technology

[0002] Headphones are audio devices worn on the head and covering both ears. They offer significant advantages in sound quality, comfort, and functionality, making them suitable for users with high demands for audio experience. They are also suitable for long-term wear, providing good sound quality and noise isolation, and have gained widespread attention from consumers.

[0003] Common over-ear headphones mainly consist of earcups, headband, and driver units. The earcups are located at both ends of the headband, and the driver units are located inside the earcups. When using them, first adjust the length of the headband, then put the earcups on and wrap them around your ears. By controlling the driver units, you can produce sound effects and achieve a good user experience.

[0004] With technological advancements, the functions and materials of headphones have been continuously enriched and improved. Some headbands are made by assembling two shells together. Furthermore, some headphones also have a folding function. Specifically, a hinge is usually set in the area near the end of the headband so that the earcups can be bent and stored, further improving the user experience.

[0005] However, the current foldable headband structure still has many shortcomings. For example, the core component of the hinge is usually the pivot. During the installation of the pivot to the two shells, there is a risk of insufficient stability in the pivot assembly, which can lead to structural loosening and may also affect the tightness of the connection between the two shells. Therefore, the existing technology still lacks a solution that can effectively improve the stability of the pivot assembly, so improvement is needed.

[0037] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0039] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0040] The following is in conjunction with the appendix Figure 1-8 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0041] Example 1:

[0042] Please refer to Figure 1This utility model provides a headphone hinge structure, including a shell 1, an internal component 2, and a hinge 3.

[0043] The outer shell 1 and the built-in component 2 can be understood as part of the head beam. For ease of distinction, the part of the head beam excluding the outer shell 1 and the built-in component 2 is defined as the head beam body. The outer shell 1 and the built-in component 2 are usually assembled at both ends of the head beam body.

[0044] Optionally, the materials of the outer shell 1 and the internal components 2 can be the same or different.

[0045] When the outer shell 1 and the inner component 2 are made of different materials, in one embodiment, the outer shell 1 is made of metal and the inner component 2 is made of plastic, which facilitates structural design and further enhances the texture and feel of the headband; in another embodiment, the outer shell 1 can also be made of plastic and the inner component 2 can be made of metal, which also enhances the texture and feel of the headband.

[0046] It is understood that no restrictions are placed on the specific material settings of the outer shell 1 and the internal component 2. As long as the two use the same material or two different materials, they should be included in the scope of interpretation of this application.

[0047] Combination Figure 2 The outer shell 1 is provided with a first mounting hole 11, and the inner component 2 is provided with a second mounting hole 21. The inner component 2 is connected to the outer shell 1. When the two are connected to each other, they are combined to form a long rod-shaped profile. At the same time, when the two are connected to each other, the first mounting hole 11 and the second mounting hole 21 are interconnected. The first mounting hole 11 and the second mounting hole 21 mainly serve to provide a mounting space for the rotating shaft 3.

[0048] Based on this, refer to Figure 3 The rotating shaft 3 is provided with a patterned part 31. The surface of the patterned part 31 is a rough surface. The rotating shaft 3 is press-fitted into the first mounting hole 11 and the second mounting hole 21. At this time, the patterned part 31 extends into the first mounting hole 11 and the second mounting hole 21 at the same time, and the patterned part 31 is respectively interference-fitted into the first mounting hole 11 and the second mounting hole 21.

[0049] It should be explained that the rotating shaft 3 can be installed into the first mounting hole 11 and the second mounting hole 21 by pressing. In another embodiment, it can also be installed by temperature difference method, hydraulic assembly method or expansion and contraction method. The specific installation method of the rotating shaft 3 is not limited here.

[0050] Furthermore, the interference fit between the patterned part 31 and the first mounting hole 11 and the interference fit between the patterned part 31 and the second mounting hole 21 are both ≥0.10mm. This enables the patterned part 31 to form a material extrusion effect, thereby enabling it to engage with the outer shell 1, and also enabling the patterned part 31 to engage with the inner component 2.

[0051] Understandably, in the above scheme, when the interference is less than 0.10mm, the extrusion force may be insufficient, and the shaft 3 may still be at risk of loosening. When the interference is ≥0.10mm, sufficient extrusion force can be obtained, and the shaft 3 is not easy to loosen after assembly.

[0052] For example, the interference of the patterned part 31 can be 0.10mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm, etc. The specific interference of the patterned part 31 can be adjusted according to actual needs, and no specific limitation is made here. In this embodiment, 0.15mm is selected as an example. In another embodiment, the value range of the interference can also be selected between any two of the above parameter values.

[0053] In the above scheme, by providing a patterned part 31 on the rotating shaft 3, the surface pattern of the patterned part 31 can increase the friction during the assembly of the rotating shaft 3. On this basis, by interfering with the patterned part 31 into the first assembly hole 11 and the second assembly hole 21, the connection stability between the rotating shaft 3 and the outer shell 1 can be improved, and the connection stability between the rotating shaft 3 and the built-in component 2 can also be improved. At the same time, the connection stability between the outer shell 1 and the built-in component 2 can also be indirectly optimized, thereby improving the overall structural stability.

[0054] In one embodiment provided in this example, the surface of the patterned portion 31 is a diamond pattern. The diamond pattern has a dense diamond grid pattern, which can significantly improve the surface roughness of the patterned portion 31, thereby enabling the patterned portion 31 to stably engage with the outer shell 1 and the internal component 2, resulting in a more stable connection.

[0055] In other embodiments, the surface of the patterned portion 31 can also be equivalently replaced with a checkered pattern, a wavy pattern, or a threaded structure. Here, regardless of the specific texture used on the surface of the patterned portion 31, as long as it can improve the surface roughness of the patterned portion 31, it should be included in the equivalent interpretation scope of this solution. The specific solutions shown in the embodiments of this application are not intended to be specific limitations on the actual protection scope of this application.

[0056] Furthermore, continue to refer to Figure 2 and Figure 3The patterned part 31 is located at the end of the rotating shaft 3. Specifically, in this embodiment, the patterned part 31 is located at one end of the rotating shaft 3. In this embodiment, the outer shell 1 has wing portions 12 bent to one side on opposite sides of its end, and the first mounting holes 11 are respectively disposed through the two wing portions 12. At the same time, the inner component 2 has a connecting protrusion 22 at one end. There are also two connecting protrusions 22, and the two connecting protrusions 22 are located on opposite sides of the inner component 2. When the outer shell 1 and the connecting protrusions 22 are connected to each other, the wing portions 12 and the connecting protrusions 22 are paired up in pairs. At this time, the first mounting hole 11 and the second mounting hole 21 can be arranged adjacent to each other, and the ends of the first mounting hole 11 and the second mounting hole 21 are directly opposite each other, so that the first mounting hole 11 and the second mounting hole 21 are in a state of mutual communication, thereby forming two sets of first mounting holes 11 and second mounting holes 21 that are interconnected.

[0057] At this time, the patterned part 31 located at one end of the rotating shaft 3 can form an assembly relationship with one of the pairs of first assembly holes 11 and second assembly holes 21. This means that the rotating shaft 3 can be pressed in from either side of the outer shell 1 and the inner component 2 during assembly. The assembly process is quick and convenient, and the installation difficulty is low.

[0058] Optionally, in another embodiment, the patterned portion 31 can also be provided at both ends of the rotating shaft 3, so that the two patterned portions 31 can form an assembly relationship with the two sets of matching first assembly holes 11 and second assembly holes 21 respectively, and the assembly stability of the rotating shaft 3 can be further optimized and improved.

[0059] Furthermore, the outer diameter of the patterned part 31 is larger than the outer diameter of the rotating shaft 3. At this time, a stepped shaft structure is formed between the body of the rotating shaft 3 and the patterned part 31, which has good structural strength. On this basis, the outer diameter of the patterned part 31 is ≥1.6mm.

[0060] It is understandable that when the outer diameter of the patterned part 31 is less than 1.6mm, the overall structure of the patterned part 31 is relatively thin, which may lead to deformation and affect the structural stability. When the outer diameter of the patterned part 31 is greater than or equal to 1.6mm, the patterned part 31 can have good structural strength, the structure is not easily deformed, and it meets the usage requirements.

[0061] For example, the outer diameter of the patterned portion 31 can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, etc., and the size of the patterned portion 31 is not specifically limited here; in another embodiment, the value range of the patterned portion 31 can also be selected between any two of the above values.

[0062] Furthermore, referring to Figure 2 To ensure a stable connection between the outer shell 1 and the inner component 2, the first mounting hole 11 is located at one end of the outer shell 1, while the other end of the outer shell 1 is provided with a first fastening position 4; the second mounting hole 21 is located at one end of the inner component 2, while the other end of the inner component 2 is provided with a second fastening position 5, and the second fastening position 5 and the first fastening position 4 are fastened to each other.

[0063] Specifically, in one embodiment, the first fastening position 4 can be a fastening protrusion, and the second fastening position 5 can be a fastening recess. With the cooperation of the fastening protrusion and the fastening recess, the first fastening position 4 and the second fastening position 5 can be fastened together. In another embodiment, the first fastening position 4 can be a fastening recess, and the second fastening position 5 can be a fastening protrusion. In this way, the fastening function between the first fastening position 4 and the second fastening position 5 can also be achieved. The specific structural form of the first fastening position 4 and the second fastening position 5 is not limited here. As long as the two can be fastened together, they should be included in the technical scope of this application.

[0064] Based on the above configuration, the pivot 3 can fix one end of the outer shell 1 to one end of the inner component 2, while the first fastener 4 and the second fastener 5 can quickly fasten the other end of the outer shell 1 to the other end of the inner component 2. On the one hand, it can fix the outer shell 1 and the inner component 2 to each other and make the connection stable; on the other hand, it can also realize the quick installation between the outer shell 1 and the inner component 2, reducing the assembly difficulty of the outer shell 1 and the inner component 2.

[0065] Furthermore, referring to Figure 4 The headphone hinge mechanism disclosed in this embodiment also includes a built-in connector 6. It can be understood that the built-in connector 6 is typically used to connect with the earcups, serving to assemble the earcups and ear bridge together, and the built-in connector 6 also serves to drive the earcups to rotate, so as to realize the folding and storage function of the headphones.

[0066] The built-in connector 6 has a third mounting hole 61 through it. When the rotating shaft 3 is installed into the first mounting hole 11 and the second mounting hole 21, it is also inserted into the third mounting hole 61. The built-in connector 6 and the rotating shaft 3 are rotatably engaged.

[0067] By adopting the above technical solution, under the action of the third assembly hole 61, the built-in connector 6 achieves a rotatable connection with the outer shell 1 and the built-in component 2, etc., with a stable structure and not easy to loosen.

[0068] Furthermore, the sound-generating elements within the earcups typically require wires for connection, and these wires need to be routed around the ear bridge to allow the sound-generating elements in both earcups to communicate with each other. Based on this, refer to... Figure 5To facilitate wire routing, a first wire groove 7 is provided between the outer shell 1 and the internal component 2. In addition, a second wire groove 8 is provided on the internal connector 6. The first wire groove 7 and the second wire groove 8 are interconnected. At this time, the wire can pass through the second wire groove 8 into the first wire groove 7, and then enter the ear beam through the first wire groove 7, realizing hidden wiring. The compactness of the structure and the overall aesthetics are optimized and improved.

[0069] It is understood that, in one embodiment, the first wire groove 7 may be recessed on the surface of the outer casing 1 facing the inner member 2, and in another embodiment, the first wire groove 7 may also be recessed on the surface of the inner member 2 facing the outer casing 1. No specific limitation is made on the forming method of the first wire groove 7; any scheme that uses a groove feature to accommodate the wire should be included within the scope of protection of this application.

[0070] Furthermore, during the folding and storage of the earcups, there is a problem with the poor connection stability between the hinge 3 and the built-in connector 6, which may cause the earcups to loosen and fall off on their own, thus making it impossible for the earcups to maintain a stable folded state and affecting the user experience.

[0071] To overcome the above-mentioned technical obstacles, refer to Figure 6 The outer shell 1 or the internal component 2 is provided with an internal spring 9. It is understood that the internal spring 9 can be fixedly set on the outer shell 1 or the internal component 2 according to actual needs. There is no restriction on the specific assembly position of the internal spring 9. In this embodiment, the internal spring 9 is fixedly set on the inner wall of the outer shell 1 and located in the first groove 7. In this way, the internal space of the first groove 7 can be used to accommodate the internal spring 9, making the structure more compact and beautiful.

[0072] Based on this, the built-in spring 9 has a locking bend 91. Specifically, the built-in spring 9 in this embodiment includes two interconnected support arms, which are connected to each other and have an overall L-shaped outline. One support arm is used to fix it to the outer shell 1, while the other support arm extends in a direction away from the outer shell 1. At the same time, the middle area of ​​the extended portion is recessed towards the location of the built-in connector 6 to form the locking bend 91, and, combined with Figure 7 and Figure 8 On the opposite sides of the bend in the locking position 91, a first locking point 92 and a second locking point 93 are formed respectively.

[0073] Based on this, one end of the built-in connector 6 is provided with a cam locking part 10. The cam locking part 10 protrudes towards the location of the locking bending part 91 and abuts against the locking bending part 91. In addition, the protruding part of the cam locking part 10 has a certain outward protrusion length, which is just enough to lift the locking bending part 91 so that the locking bending part 91 can be elastically deformed.

[0074] Based on the above configuration, during the rotation of the built-in connector 6, the cam locking part 10 can reciprocate between the first locking point 92 and the second locking point 93. During this process, the cam locking part 10 pushes the locking bending part 91 to deform, thereby causing the built-in spring 9 to avoid the cam locking part 10, and thus allowing the cam locking part 10 to reciprocate and engage with the locking bending part 91 on both sides. That is, the cam locking part 10 can form limiting resistance with the built-in spring 9 at the first locking point 92 and the second locking point 93 respectively.

[0075] At this time, the built-in connector 6 has the following positional state:

[0076] When the built-in connector 6 is engaged at the first engagement point 92, the built-in connector 6 can extend horizontally relative to the outer shell 1 or the built-in component 2, which is equivalent to the earcup being in an open state relative to the ear bridge body.

[0077] When the built-in connector 6 is engaged in the second slot, the built-in connector 6 can be folded relative to the outer shell 1 or the built-in component 2, which is equivalent to the earcups being folded relative to the ear bridge.

[0078] During the switching between the two states, on the one hand, the cam locking part 10 can generate a passing feel as it passes through the locking bending part 91, and the deformation of the locking bending part 91 applies force to produce a limiting effect, so that the earphone neckband is not easy to fall off when folded; on the other hand, it also reminds the user to reach the optimal rotation angle of the cable to avoid excessive folding damage to the cable.

[0079] Optionally, when the built-in connector 6 pushes the bent portion 91 to deform, the relative rotation angle of the built-in connector 6 is 30°-90°. It can be understood that the relative rotation angle of the built-in connector 6 can be understood as the rotation angle of the built-in connector 6 relative to the outer shell 1 and the built-in component 2, based on the straight extended state. At this time, when the built-in connector 6 pushes the bent portion 91 to deform, it will produce a slight over-touch feel. The above setting is equivalent to controlling the rotation angle that produces this over-touch feel between 30° and 90°.

[0080] With the above-mentioned settings, when the rotation angle that produces the over-touch feel is less than 30°, there is a problem of premature limiting, resulting in insufficient folding space for the earcups and poor earcup storage. When the rotation angle that produces the over-touch feel is greater than 90°, the wire may bend too much, which can easily damage the wire. Therefore, this embodiment of the application limits the relative angle of the built-in connector 6 to the range of 30° to 90°, which can both meet the storage space requirements and avoid excessive bending of the wire and damage.

[0081] For example, the relative rotation angle of the built-in connector 6 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 70°, 75°, 80°, 85° or 90°, etc., and there is no limitation on the specific relative rotation angle of the built-in connector 6. In another embodiment, the value range of the relative rotation angle of the built-in connector 6 can also be selected between any two of the above parameter values.

[0082] Therefore, the headphone hinge structure provided in this embodiment has the following beneficial effects:

[0083] 1. In situations where the product structure space is small and the addition of parts is limited, by adding a patterned part 31 to the pivot 3, the engagement of the outer shell 1 and the internal component 2 can be controlled, making the structural connection more secure, which is suitable for the hinge installation of headphones.

[0084] 2. The first wire groove 7 and the second wire groove 8 can facilitate the concealment of wires and the structure is beautiful and compact;

[0085] 3. The built-in connector 6 provides a smooth feel when rotating, making the folding and storage action more stable and reliable, and effectively reminding the user to operate, thus optimizing and improving the user experience.

[0086] Example 2:

[0087] Based on Embodiment 1, features not explained in this embodiment are explained using the methods described in Embodiment 1, and will not be repeated here. This embodiment further provides an earphone, including the headphone hinge structure described in Embodiment 1.

[0088] In addition, it also includes the headband body, earcups, and sound-generating elements. The outer shell 1 and the internal component 2 are set on the headband body. The internal connector 6 is connected to the outer shell 1 and the internal component 2 through the rotating shaft 3. The internal connector 6 is rotatably set on the rotating shaft 3, and the earcups are set on the internal connector 6. At the same time, the sound-generating elements are set at the earcups.

[0089] By adopting the above configuration scheme, a headset with stable connection and good operating feel was finally obtained.

[0090] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
