[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Existing clip-on headphones typically employ a fixed structural design, with a fixed connection between the earpiece assembly and the main body shell. This lack of flexible adjustment results in insufficient wearing comfort and affects sound quality. Specifically, in existing clip-on headphone structures, because the earpiece assembly is fixed in position, users often find it difficult to achieve optimal acoustic matching, thus affecting sound quality and wearing stability. This is especially problematic for users with significant differences in ear canal depth, as the fixed earpiece position can lead to reduced sound transmission efficiency and discomfort during wear.

[0040] Based on this, see Figures 1 to 8As shown, this utility model embodiment provides an ear clip-on earphone 10, which includes a main unit assembly 100 and a handset assembly 200; the main unit assembly 100 includes a main unit housing 110 and a connecting structure 120, one end of the connecting structure 120 being connected to the main unit housing 110; the handset assembly 200 is connected to the end of the connecting structure 120 away from the main unit housing 110, and the position of the handset assembly 200 relative to the connecting structure 120 is telescopically adjustable.

[0041] The ear clip-on earphone 10 of this embodiment effectively solves the problem of insufficient wearing comfort and sound quality caused by the fixed position of the earpiece in the prior art by designing the earpiece assembly 200 as detachable and telescopically adjustable relative to the connecting structure 120.

[0042] By using the retractable and adjustable earpiece assembly 200 in conjunction with the main unit assembly 100, users can flexibly adjust the position of the earpiece assembly 200 according to their own ear canal depth to achieve better acoustic matching, thereby improving sound transmission efficiency, reducing sound loss, and improving sound quality. At the same time, the retractable and adjustable connection structure 120 enhances wearing stability, reduces discomfort caused by improper earpiece position, and provides a good user experience.

[0043] Specifically, the earpiece assembly 200 can be adjusted in several ways, including sliding, rotating, or snapping. This allows users to select the appropriate earpiece position based on differences in ear canal depth and shape. For example, the distance between the earpiece assembly 200 and the main housing 110 can be set to multiple levels, such as 1 mm, 2 mm, 3 mm, 5 mm, and 10 mm. These values ​​can be adjusted according to actual design requirements to ensure that the wearing needs of different users are met while avoiding excessively long connection structures that could affect the overall stability and portability of the ear-clip headphones. If the adjustment range is too small, some users may not achieve the ideal wearing comfort and sound quality; if the adjustment range is too large, it will increase structural complexity and manufacturing costs, and may also affect the secure fit of the ear-clip headphones.

[0044] Furthermore, the ear clip-on earphone 10 also includes a telescopic structure, which includes a telescopic part 1211 and a connecting hole 2112. The telescopic part 1211 is adjustablely inserted into the connecting hole 2112 and slides in cooperation with the connecting hole 2112. Either the telescopic part 1211 or the connecting hole 2112 is provided on the connecting structure 120, and the other one is provided on the earpiece assembly 200.

[0045] First, the cooperation between the telescopic part 1211 and the connecting hole 2112 makes their relative positional relationship more stable and precise. The telescopic part 1211 passes through the connecting hole 2112, effectively limiting the radial and axial displacement of the earpiece assembly 200 along the telescopic part 1211, thereby ensuring a reliable fit at the snap-fit ​​part of the positioning structure and improving the overall connection's robustness and stability. Compared to simply relying on external clips or clamps, this structural cooperation method is more compact and structurally sound, avoiding unnecessary exposed parts and improving the overall aesthetics of the product.

[0046] Secondly, the presence of the connecting hole 2112 allows the earpiece assembly 200 to protect the telescopic part 1211. Specifically, the connecting hole 2112 surrounds a portion of the connecting structure 120, effectively preventing damage such as bumps, scratches, or impacts to the connecting structure 120 during use due to external collisions, drops, or friction. This protection not only extends the service life of the connecting structure 120 but also reduces the risk of connection failure due to structural damage, improving the overall durability and reliability of the clip-on earphone.

[0047] Furthermore, the cooperation between the telescopic part 1211 and the connecting hole 2112 enables a compact structural design. By embedding the telescopic part 1211 inside the connecting hole 2112 of the earpiece assembly 200, exposed and expanded connecting parts are avoided, reducing the overall size of the assembly and facilitating a thinner, more ergonomic ear clip-on headphone design. This compact structural design is particularly important for portable electronic devices, effectively saving space and improving wearing comfort.

[0048] In practical implementation, the size and shape of the connecting hole 2112, as well as the fitting clearance with the telescopic part 1211, can be optimized according to actual needs. The size of the connecting hole 2112 can be slightly larger than that of the telescopic part 1211 to ensure smooth installation, while cooperating with the protrusions and recesses of the positioning structure to achieve a secure snap-fit.

[0049] See Figures 1 to 8 In the illustrated embodiment, the telescopic part 1211 is disposed on the connecting structure 120, and the connecting hole 2112 is located on the earpiece assembly 200. In this structure, the telescopic part 1211 passes through the connecting hole 2112 and slides in cooperation with the connecting hole 2112, realizing the telescopic adjustment of the earpiece assembly 200 relative to the connecting structure 120. This design makes the connection between the connecting structure 120 and the earpiece assembly 200 more stable and compact, effectively preventing loosening of the connection part and improving the wearing security and comfort.

[0050] In other embodiments, the telescopic portion 1211 can also be disposed on the earpiece assembly 200, and the telescopic portion 1211 extends outward from the outer wall of the earpiece assembly 200, while the connecting hole 2112 is correspondingly located within the connecting structure 120. This reverse configuration also enables the sliding engagement of the telescopic portion 1211 and the connecting hole 2112, thereby achieving positional adjustment between the earpiece assembly 200 and the connecting structure 120. The advantage of this structure is that the positions of the telescopic portion and the connecting hole can be flexibly designed according to different overall product structural layouts, which helps to optimize the overall appearance and internal space utilization of the headphones, and also facilitates personalized adjustments to meet the needs of different users.

[0051] It should be noted that both structural designs can ensure the fitting accuracy and smooth sliding between the telescopic part 1211 and the connecting hole 2112, avoiding any impact on the adjustment effect due to loosening or jamming of the connecting parts. In actual implementation, the dimensions, tolerances, and surface treatment parameters of the telescopic part 1211 and the connecting hole 2112 can be optimized according to actual needs to balance the convenience of adjustment and the robustness of the connection.

[0052] Furthermore, in some embodiments, the main housing 110 and the connecting structure 120 can also be adjusted via a similar telescopic structure. That is, corresponding telescopic parts and connecting holes are provided between the main housing 110 and the connecting structure 120, allowing for axial positional adjustment between the two. This design further enhances the flexibility of the overall headphone structure, enabling users not only to adjust the position of the earpiece assembly 200, but also to adjust the relative position between the main housing 110 and the connecting structure 120 according to their own ear shape and wearing habits, thereby achieving better wearing comfort and stability.

[0053] By incorporating an adjustable telescopic structure between the main housing 110 and the connecting structure 120, the headphone can adapt to differences in head shape and ear shape, improving overall fit and user experience. Simultaneously, this multi-layered adjustment mechanism helps achieve more precise acoustic matching, thereby further optimizing sound transmission efficiency and sound quality.

[0054] In summary, regardless of whether the telescopic part 1211 is located on the connecting structure 120 or the earpiece assembly 200, and whether a telescopic structure is provided between the main housing 110 and the connecting structure 120, flexible adjustment of each connecting part of the earphone can be achieved to meet the wearing needs of different users, improve wearing comfort and sound quality, while ensuring the firmness of the connection and the compact and beautiful structure.

[0055] Specifically, the earpiece assembly 200 includes an earpiece housing 210 and a sound-generating unit 220. The earpiece housing 210 includes a connecting section 211 and a housing structure 212, which can be integrated or separate. When an integrated structure is used, the connecting section 211 and the housing structure 212 are manufactured using an integral molding process, resulting in a more compact structure and higher overall strength. This improves the durability and sealing of the clip-on earphones and reduces the risk of internal components being affected by the external environment.

[0056] In some embodiments, the connecting segment 211 and the housing structure 212 adopt a separate structure design, which allows the two parts to be manufactured from different materials. Specifically, the connecting segment 211 can be made of high-strength, wear-resistant engineering plastics or metal materials, such as polyamide (PA), polycarbonate (PC), aluminum alloy, etc., to enhance the connection strength between the connecting segment 211 and the connecting structure 120 and prevent damage to the connecting segment 211 due to frequent assembly and disassembly or external forces. The housing structure 212 can be made of lightweight materials with good acoustic properties, such as ABS plastic or silicone, to improve wearing comfort and the sound quality performance of the speaker unit 220. Through the separate structure design, not only can the material performance be optimized and matched, but it also facilitates individual replacement and maintenance, reduces maintenance costs, and improves the practicality and environmental friendliness of the product.

[0057] A connection hole 2112 is provided on the connection section 211, and the telescopic part 1211 is inserted into the connection section 211. This design ensures a stable connection between the connection structure 120 and the earpiece assembly 200, while utilizing the material advantages of the connection section 211 to enhance the overall reliability and durability of the connection.

[0058] The sound-generating unit 220 is installed inside the housing structure 212 and is responsible for converting the electrical signals transmitted from the main unit 100 into sound signals to realize the audio playback function. The sound-generating unit 220 is connected to the main unit 100 via a cable 400.

[0059] In one embodiment, the connecting segment 211 extends at least partially toward the interior of the housing, and one end of the connecting segment 211 toward the interior of the housing structure 212 is provided with a receiving groove 2114 communicating with the connecting hole 2112. The receiving groove 2114 is used to receive the cable 400 between the earpiece assembly 200 and the main unit assembly 100.

[0060] First, the receiving groove 2114 provides a dedicated space for the cable 400, enabling it to be effectively positioned and protected within the connection section 211. Guided and constrained by the receiving groove 2114, the cable 400's routing path is more standardized, preventing free swinging or compression of the cable within the ear clip-on headphones. This reduces the risk of damage caused by uneven cable stress or friction, improving cable lifespan and overall signal transmission stability.

[0061] Secondly, the inclusion slot 2114 makes the overall structure formed by the earpiece assembly 200 and the connecting structure 120 more compact. Without affecting the cable 400 wiring, the connecting section 211 uses the internal inclusion slot to rationally arrange the cable layout, avoiding exposed cables or occupying extra space, thus improving the volume utilization and aesthetics of the clip-on headphones. Especially in the trend of lightweight and miniaturized design for clip-on headphones, this structural design effectively balances functionality and aesthetics, meeting the needs of ergonomics and user comfort.

[0062] Furthermore, the receiving slot 2114 facilitates the installation and maintenance of the cable 400. The cable can be guided to a predetermined position through the receiving slot, enabling quick and accurate assembly and reducing assembly difficulty and time costs. At the same time, the presence of the receiving slot also facilitates later inspection, repair, or replacement of the cable, improving the maintainability and ease of use of the product.

[0063] Furthermore, the ear clip-on earphone 10 also includes a guide structure, which includes a guide groove 2113 and a guide portion 1214. Either the guide groove 2113 or the guide portion 1214 is provided on the telescopic portion 1211, and the other of the guide groove 2113 or the guide portion 1214 is provided on the earpiece assembly 200. The guide portion 1214 slides in conjunction with the guide groove 2113, thereby significantly improving the smoothness and accuracy of adjustment of the earpiece assembly 200.

[0064] Specifically, the guide structure is designed to provide more precise positioning and adjustment functions. The presence of the guide groove 2113 effectively guides the movement trajectory of the guide part 1214, reducing jamming or unevenness caused by errors, and ensuring the flexibility and stability of the ear clip headphones during adjustment. This sliding fit not only ensures the smoothness of the earpiece assembly 200 during movement, but also improves the user's operating experience, making the ear clip headphones more convenient to adapt to different wearing needs.

[0065] In some embodiments, the extension direction of the guide structure may be parallel to or at an angle to the axis of the connecting hole 2112. This design not only optimizes the structural layout of the ear clip-on headphones but also provides an anti-rotation function between the earpiece assembly 200 and the connecting structure 120, effectively limiting unnecessary rotation of the ear clip-on headphones during use and enhancing the overall structural stability.

[0066] Furthermore, the design of the guide structure takes into account the needs of different usage scenarios. If the guide slot 2113 and guide part 1214 are configured as a combination of multiple slots and components, specifically including two or more guide slots and guide parts, this provides a more flexible adjustment method, allowing users to make more precise adjustments according to personal comfort and usage habits. The configuration of multiple guide slots and guide parts enables a wider range of adjustments, adapting to different wearing angles and positions, further enhancing the user experience of clip-on headphones.

[0067] In addition, the choice of materials for the guide structure is also crucial. High-strength, low-friction materials, such as polytetrafluoroethylene (PTFE) or nylon, are recommended to ensure smooth sliding and durability. These materials not only reduce wear and extend service life but also offer some protection against environmental factors that can affect the performance of clip-on headphones, such as temperature and humidity changes.

[0068] In one embodiment, the connection structure 120 includes a connector 121 and an anti-detachment component 122. One end of the connector 121 is connected to the main housing 110, and the other end of the connector 121 passes through the connection hole 2112. The anti-detachment component 122 is detachably connected to the connector 121 and is located inside the earpiece assembly 200. The outer periphery 1221 of the anti-detachment component 122 extends outward at least partially and is used to abut against the earpiece assembly 200 to securely contact the earpiece assembly 200 and prevent the assembly from loosening or falling off during use.

[0069] In this embodiment, the anti-dislodgement component 122 can be threadedly connected to the connector 121. This connection method not only simplifies the assembly process but also allows for convenient disassembly and maintenance when needed, improving the ease of use of the clip-on earphone. When the earpiece assembly 200 moves to the end of the path, the anti-dislodgement component 122 can abut against the open end face of the connecting hole 2112, thereby effectively limiting the movement of the earpiece assembly 200 relative to the connecting structure 120, ensuring the safety and stability of the clip-on earphone during use.

[0070] Specifically, the anti-slip element 122 can be a screw, with its outer periphery 1221 evenly distributed along the outer circumference of the anti-slip element 122. This design not only enhances the contact area between the anti-slip element 122 and the earpiece assembly 200, but also improves its tensile strength and shear resistance, ensuring that it is not easily detached or damaged under external forces. Furthermore, there can be multiple outer periphery 1221s, specifically two, three, or more, and these outer periphery 1221s are spaced apart along the outer circumference of the anti-slip element 122 to form a serrated structure. This serrated structure design further enhances the gripping force of the anti-slip element 122 when it abuts against the earpiece assembly 200, reducing the possibility of slippage, thereby improving the overall stability and durability of the clip-on earphone.

[0071] Furthermore, the telescopic structure also includes a limiting flange 1212, which is disposed on the telescopic part 1211 and extends outward from the outer peripheral wall of the telescopic part 1211. The limiting flange 1212 is located on the outside of the earpiece assembly 200 and is used to abut against the earpiece assembly 200.

[0072] In the above structure, the design of the limiting flange 1212 plays an important role in ensuring the safe and reliable movement of the earpiece assembly 200 within the adjustment range. Specifically, the limiting flange 1212 is provided on the outer peripheral wall of the telescopic part 1211 and extends outward from the outside of the telescopic part 1211. When the earpiece assembly 200 moves to its limit position along the telescopic path, it abuts against the outer wall of the earpiece assembly 200, thereby achieving a limited position.

[0073] The main advantages of this limiting structure are: First, it effectively prevents the earpiece assembly 200 from detaching from the connecting structure 120 due to over-adjustment, ensuring the safety and stability of the adjustment. Second, the limiting flange 1212 can prevent the earpiece assembly 200 from accidentally falling off under violent movement or external force, improving the product's durability and user confidence. Furthermore, since the limiting flange 1212 is located on the telescopic part 1211, the structure is simple, easy to manufacture and assemble, and does not significantly increase the overall size of the earphone.

[0074] In practical applications, the design of the limiting flange 1212 and the outer wall of the earpiece assembly 200 should ensure sufficient buffer space within the adjustment range to avoid excessively tight or loose fits affecting the smoothness of adjustment. For example, the limiting flange 1212 can be designed as a material or structural deformation zone with a certain degree of elasticity to absorb minor errors or vibrations that may occur during adjustment, thereby further improving the smoothness of adjustment and the user experience.

[0075] In summary, the limiting flange 1212 provided on the telescopic part 1211, through its cooperation with the outer wall of the earpiece assembly 200, provides effective protection against movement limits, ensuring that the earpiece assembly moves safely and stably within the adjustment range, thereby improving the overall performance and reliability of the headphones.

[0076] In one embodiment, the housing structure 212 consists of a first housing 2121 and a second housing 2122, which are fastened together to form a complete housing structure 212. Specifically, a connecting segment 211 can be disposed on the first housing 2121 to achieve effective connection with the connecting structure 120. During assembly, the connector 121 can be inserted into the connecting segment 211 from the opening of the connecting hole 2112 away from the second housing 2122, and then the anti-detachment component 122 can be connected and fixed to the connector 121 from the side of the first housing 2121 facing the second housing 2122. This assembly method has a reasonable structure and a clear path, which not only ensures the stability of the connecting structure, but also facilitates disassembly and maintenance, greatly improving the operational convenience for users and production lines.

[0077] The connection between the first housing 2121 and the second housing 2122 can take several forms, including screw connection, snap-fit ​​connection, and magnetic connection. Screw connection offers a robust structure, suitable for applications requiring high mechanical strength and durability, ensuring a tight fit between the two housings and preventing loosening. Snap-fit ​​connection is simple in structure, quick to assemble and disassemble, and suitable for product designs requiring frequent maintenance or replacement of the sound unit 220. Magnetic connection offers the advantage of rapid adsorption and disassembly, improving assembly efficiency while achieving good sealing and structural aesthetics.

[0078] Specifically, the anti-detachment component 122 can also be installed over the opening of the receiving groove 2114 to effectively limit the installation of the cable 400. By covering the opening of the receiving groove 2114 with the anti-detachment component 122, the cable 400 can be prevented from slipping out or shifting from the receiving groove 2114 due to pulling or vibration during use, ensuring that the cable 400 always remains in the predetermined wiring position and improving the reliability of cable fixation.

[0079] Furthermore, the anti-dislodgement component 122, located at the opening of the receiving slot 2114, also serves a protective function, preventing the cable 400 from direct contact with external objects. This reduces the risk of cable damage caused by external pressure, friction, or collision, thus improving the cable's durability and lifespan. Simultaneously, this structural design ensures neat cable routing, preventing tangled cables from affecting the overall appearance of the earbuds and user comfort.

[0080] By combining the threaded connection between the anti-detachment component 122 and the connector 121, the anti-detachment component 122 can be securely fixed to the connector 121, effectively limiting the cable 400 without affecting the adjustment function of the earpiece assembly 200. This design balances the safety of cable routing with the flexibility of the overall structure of the ear clip-on headphones, further improving the overall performance and user experience of the ear clip-on headphones 10.

[0081] Specifically, the earcup earphone 10 also includes a positioning structure. The earpiece assembly 200 and the main body housing 110 are adjustablely positioned and connected via the positioning structure. The positioning structure includes a first positioning part 1213 and a second positioning part 2111. Either the first positioning part 1213 or the second positioning part 2111 is disposed on the connecting structure 120, and the other of the first positioning part 1213 and the second positioning part 2111 is disposed on the earpiece assembly 200. The first positioning part 1213 is detachably connected to the second positioning part 2111, ensuring that the position of the earpiece assembly 200 relative to the connecting structure 120 can be stably and flexibly adjusted. The introduction of the positioning structure is to solve problems such as loosening and falling off that may occur during adjustment and use of the earpiece assembly 200, thereby improving the overall structural reliability and user experience of the earcup earphone.

[0082] Specifically, one of the first positioning part 1213 and the second positioning part 2111 is disposed on the connecting structure 120, and the other is disposed on the earpiece assembly 200. Through the cooperation of these two positioning components, precise positioning and a secure connection of the earpiece assembly 200 are achieved. The positioning structure not only allows for position adjustment of the earpiece assembly 200 on the connecting structure 120, but also ensures that the adjusted position will not shift or separate due to external forces, thereby avoiding sound quality fluctuations or wearing discomfort caused by earpiece loosening during wear.

[0083] The connection between the first positioning part 1213 and the second positioning part 2111 in the positioning structure can be achieved through a snap-fit ​​connection. This method is simple in structure, low in manufacturing cost, and easy to operate, making it particularly suitable for quick disassembly and installation when users adjust the position themselves. The advantage of the snap-fit ​​connection is that disassembly and installation can be completed without additional tools, which allows users to flexibly adjust the position of the earpiece assembly 200 according to their own needs, improving the personalization and comfort of wearing it.

[0084] In some specific embodiments, the positions of the first positioning part 1213 and the second positioning part 2111 can be interchanged. That is, the first positioning part 1213 can be disposed on the earpiece assembly 200, and the second positioning part 2111 can be disposed on the connecting structure 120. This design provides more structural freedom, which makes it easier to optimize the component layout and adjustment method according to different ear clip-on headphone design schemes. It is not limited to a single fixed structure, which enhances the flexibility and adaptability of structural design.

[0085] Furthermore, the connection method of the first positioning part 1213 and the second positioning part 2111 is not limited to snap-fit, but can also adopt magnetic connection, pin connection, threaded connection, snap-fit ​​connection, and other methods. Magnetic connection facilitates quick disassembly and installation, improves user experience, and reduces mechanical wear while ensuring a certain connection strength; pin connection provides high mechanical strength and anti-detachment capability, suitable for applications requiring high firmness; threaded connection enables fine adjustment and stable fixation, suitable for designs requiring high positioning accuracy; snap-fit ​​connection balances convenient disassembly and stable connection. Further, there can be multiple first positioning parts 1213 and / or second positioning parts 2111, with at least one first positioning part 1213 snap-fitting with at least one second positioning part 2111. This multiple arrangement not only enhances the stability of the positioning structure but also enables more precise and multi-level adjustment functions through the synergistic effect of multiple positioning components.

[0086] Specifically, the number of the first positioning part 1213 and the second positioning part 2111 can be two, three, or more, and is not limited to a single number. By setting multiple first positioning parts 1213 and second positioning parts 2111, and designing multiple locking points at their corresponding positions, users can select different locking positions according to their actual needs, realizing multi-level position adjustment of the earpiece assembly 200 relative to the connecting structure 120. For example, the connecting structure 120 has three first positioning parts 1213, and the earpiece assembly 200 has three corresponding second positioning parts 2111. Users can select any pair for locking, allowing the earpiece assembly 200 to switch arbitrarily between three preset positions to meet the needs of different ear canal depths and wearing habits.

[0087] The preset adjustment settings not only enhance usability but also ensure ease of adjustment and accurate positioning. Users can quickly adjust without complicated operations, while the secure locking mechanism prevents accidental slippage or detachment of the earpiece assembly after adjustment, ensuring stability and comfort during wear. The multi-position design also caters to the diverse needs of different user groups, expanding the product's applicability.

[0088] Understandably, when there are multiple first positioning parts 1213 and multiple second positioning parts 2111, the arrangement of multiple positioning components allows the positioning structure to distribute the force, reducing the risk of excessive force on a single point and improving the durability and reliability of the overall structure. For use scenarios involving sports or prolonged wear, multiple locking points can effectively resist external impacts and vibrations, reducing discomfort and sound quality fluctuations caused by loosening.

[0089] In one embodiment, there are multiple first positioning parts 1213, and these multiple first positioning parts 1213 are spaced apart along the extending direction of the connecting structure 120, wherein at least one first positioning part 1213 engages with a second positioning part 2111. Specifically, the number of first positioning parts 1213 can be two, three, four, or more, and the spacing distance can be flexibly determined according to actual design requirements, for example, it can be different values ​​such as 1 mm, 2 mm, 3 mm, 5 mm, etc., and is not limited to a single value here. By using this multiple and spaced arrangement, multiple engagement options can be effectively provided for the second positioning part 2111, realizing multi-level adjustment of the earpiece assembly 200 relative to the connecting structure 120.

[0090] Multiple first positioning parts 1213 are arranged at intervals along the extension direction of the connecting structure 120, which enables more precise and stable positioning of the snap-fit. Users can select different positions of the first positioning parts 1213 and the second positioning parts 2111 to achieve snap-fit, thereby adjusting the position of the earpiece assembly 200. This design not only meets the personalized needs of different users for wearing depth and comfort, but also improves the flexibility and convenience of adjustment.

[0091] Furthermore, the arrangement of multiple first positioning parts 1213 in combination with corresponding second positioning parts 2111 forms a multi-point snap-fit, which can significantly enhance the connection strength and stability between the connection structure 120 and the earpiece assembly 200. The multi-point snap-fit ​​can disperse the concentration of external forces, reduce the risk of excessive force at a single point, and prevent the earpiece assembly 200 from accidentally separating due to external forces such as vibration, impact, or pulling during daily use, thereby improving the durability and safety of the overall structure.

[0092] In one embodiment, the first positioning part 1213 is a protruding structure, and the second positioning part 2111 is at least partially a recessed structure. The two are positioned and connected through a snap-fit ​​engagement between the protruding and recessed structures. This structural engagement method has significant advantages, making the overall positioning structure more compact and stable.

[0093] Specifically, the second positioning part 2111 can be designed as a recessed shape such as a groove or a hole. A groove structure provides a longer engagement contact surface, which helps to distribute stress and improve connection strength and durability; a hole structure facilitates accurate positioning and rapid assembly. Both are suitable for different design requirements. After the protruding first positioning part 1213 is inserted into the recessed second positioning part 2111, a reliable mechanical engagement is formed, preventing relative sliding or detachment of the connected parts during use.

[0094] To further enhance the convenience and stability of the snap-fit ​​connection, the outer surface of the first positioning part 1213 is designed as an arc surface in a preferred embodiment. The arc surface allows the protruding part to be smoothly guided when entering the recessed structure, reducing resistance and jamming during installation, and facilitating quick and accurate snap-fit ​​operation for the user. Simultaneously, the arc surface effectively alleviates stress concentration during snap-fit, reducing the risk of localized material wear and deformation, thereby extending the service life of the positioning structure.

[0095] Furthermore, the combination of the raised and recessed structures not only improves the compactness of the connection but also enhances the overall structure's resistance to vibration and impact. The multi-point protrusion and recess interlocking design can evenly distribute external forces, avoiding damage caused by excessive force at a single point, ensuring a stable connection between the earpiece assembly 200 and the connecting structure 120, and reducing accidental separation caused by vibration or external impact.

[0096] This design also boasts the advantage of simplified manufacturing processes. The protrusions and recesses can be achieved through conventional processes such as injection molding, machining, or mold forming, facilitating mass production and reducing costs. Depending on specific product requirements, the size and shape of the protrusions in the first positioning part 1213, as well as the depth and width of the recesses in the second positioning part 2111, can be flexibly adjusted to achieve optimal fit and user experience.

[0097] In another embodiment, the first positioning part 1213 and the second positioning part 2111 are connected by a damping connection to achieve an adjustable positioning connection. A damping connection typically refers to a connection between two connecting parts with a damping element or mechanism, which provides resistance through friction or elasticity, thereby achieving a connection effect that allows for smooth movement while preventing position slippage during adjustment.

[0098] The advantage of using a damped connection is that it provides the user with appropriate resistance feedback when adjusting the position of the earpiece assembly 200 relative to the connecting structure 120, preventing excessive looseness or unstable sliding during adjustment and improving the accuracy and feel of the adjustment. At the same time, the damped connection effectively prevents the earpiece assembly 200 from shifting position due to vibration or shaking caused by external forces during wear, enhancing stability and comfort. This is especially important for users who exercise or wear the earpiece for extended periods, ensuring a stable sound transmission path and preventing sound quality fluctuations.

[0099] The specific implementation of the damping connection can be varied. For example, a combination of a spring and a friction surface can be used to apply a preload using an elastic element, generating a moderate frictional force between the first positioning part 1213 and the second positioning part 2111. Alternatively, elastic materials such as rubber rings or silicone pads can be used as the damping medium to provide buffering and resistance. Furthermore, a damping mechanism with gears or ratchet structures can be designed to achieve graded resistance adjustment through mechanical meshing, meeting the different adjustment force requirements of various users.

[0100] It should be noted that the resistance of the damping connection should be designed reasonably based on the ease of user adjustment and the stability of wearing the device. Too little resistance may cause the earpiece assembly 200 to loosen or slip during use, affecting wearing comfort and sound quality stability; too much resistance may increase the difficulty of adjustment and reduce the user experience. Generally, the resistance range can be achieved by adjusting parameters such as spring stiffness, friction surface material, and contact area; the specific values ​​can be determined based on the actual product design requirements.

[0101] Furthermore, the damping connection structure can be combined with other positioning methods (such as snap-fit ​​and magnetic attraction) to further enhance the versatility and reliability of positioning. For example, the damping connection is used to achieve continuous and smooth adjustment, while the snap-fit ​​structure is used to quickly position multiple preset gears. The combination of the two can balance the flexibility of adjustment and the stability of positioning.

[0102] Furthermore, the positioning structure is at least partially located within the connection hole 2112.

[0103] First, the protruding portion of the connecting segment 211 forms a large contact surface with the connector 121, effectively increasing the connection area between the two and thus significantly improving the connection strength. The larger contact surface helps to disperse the stress borne by the connection part, reduce local stress concentration, reduce the risk of loosening between the connector 121 and the connecting segment 211 due to friction or vibration, and ensure the overall mechanical stability of the ear clip headphones.

[0104] Secondly, the connection hole 2112, when placed on the positioning structure, creates a covering between the earpiece assembly 200 and the connector 121, enhancing stability during relative movement. This covering structure restricts irregular wobbling and swinging of the earpiece assembly 200 on the connection structure 120, improving the smoothness and positioning accuracy of the adjustment process. This allows the wearer to more stably fix the earpiece position, ensuring good wearing comfort and stable acoustic performance.

[0105] Furthermore, the connection hole 2112, when covered on the positioning structure, effectively provides dust protection. This covered portion acts as a physical barrier, preventing dust, dirt, and other tiny particles from entering the positioning structure, thus avoiding the accumulation of foreign matter that could affect its normal movement and engagement, and extending the lifespan of the clip-on headphones.

[0106] See Figure 7 and Figure 8As shown, in another embodiment, the ear clip-on earphone 10 further includes a flexible positioning member 300, which is sleeved on the telescopic part 1211 and located between the telescopic part 1211 and the connecting hole 2112. By providing this flexible positioning member 300, which fits tightly with the telescopic part 1211 and the connecting hole 2112, the relative movement between the connecting structure 120 and the earpiece assembly 200 can be elastically limited.

[0107] Specifically, the flexible positioning element 300 is made of elastic materials such as rubber or silicone rings. Utilizing its excellent elasticity and cushioning properties, it provides appropriate damping and rebound force during the extension and retraction adjustment of the connecting structure and the earpiece assembly. This design not only prevents mechanical shock and wear caused by over-adjustment of the positioning structure, but also effectively avoids loosening and abnormal noises in the earpiece assembly 200 due to vibration or external forces during use, thus improving wearing stability and comfort.

[0108] Furthermore, the flexible positioning element 300 can absorb some vibration and impact, reducing mechanically transmitted vibration noise, thereby further optimizing the sound quality and wearing experience of the headphones. Thanks to the excellent wear resistance and aging resistance of the rubber and silicone ring materials, the positioning element 300 maintains its elasticity and limiting effect even after prolonged use, extending the lifespan of the headphones.

[0109] In summary, the flexible positioning component 300, as a flexible elastic limiting element, combined with the telescopic part 1211 and the connecting hole 2112, not only improves the stability and durability of the headphone adjustment structure, but also optimizes the user's wearing comfort and listening experience by buffering vibration and noise. It is an important auxiliary positioning and protection design in the ear clip-on headphones 10.

[0110] Furthermore, the telescopic part 1211 may also be provided with an installation groove for installation in conjunction with the positioning component 300. By providing a dedicated installation groove on the telescopic part 1211, the flexible positioning component 300 (such as a rubber ring or silicone ring) can be accurately embedded in the groove during installation, thereby fixing and positioning the positioning component and preventing it from shifting or slipping during use, thus improving the ease and stability of installation.

[0111] The fit between the mounting slot and the positioning component 300 not only facilitates quick and accurate installation of the positioning component by assembly personnel, reducing assembly time and process complexity, but also ensures that the positioning component 300 maintains a stable position within the headphone structure, maximizing its elastic limiting and buffering functions. Specifically, the mounting slot can be designed as an annular groove or slot, with dimensions matching the cross-section of the positioning component 300 to achieve a tight fit.

[0112] Furthermore, the mounting groove helps to secure the positioning component 300 to the telescopic part 1211, preventing displacement due to repeated movement during telescopic adjustment and ensuring that the positioning component remains in the predetermined position, thereby effectively maintaining the stability and accuracy of the telescopic structure. Simultaneously, this structural design reduces friction between the positioning component and other structural components, lowers wear, and extends the service life of the positioning component and the overall earphone.

[0113] In one embodiment, the earcup earphone 10 can be a wireless earcup earphone. In this case, the main unit 100 typically includes a control module and a battery, both housed within the main unit housing 110. The control module communicates with the sound-emitting unit 220 of the earpiece assembly 200 via a cable 400 integrated within the connection structure 120. This configuration allows the control module to receive wireless signals and drive the sound-emitting unit 220 to produce sound, while the battery provides the necessary power to ensure the normal operation of the earcup earphone.

[0114] In the design of wireless clip-on headphones, the built-in cable 400 of the connecting structure 120 not only serves the function of signal transmission but also optimizes the overall structure of the clip-on headphones, making them more compact and easier to wear. Users can adjust the position of the earpiece assembly 200 on the connecting structure 120 according to their own wearing habits to achieve optimal wearing comfort and acoustic performance. This flexible adjustment function enhances the adaptability of the clip-on headphones, meeting the personalized needs of different users.

[0115] Furthermore, the connecting structure 120 in the ear clip-on earphone 10 adopts a curved structure, such as a C-shaped or U-shaped structure. This curved structure allows the two ends of the connecting structure 120 to connect to the main housing 110 and the earpiece assembly 200 respectively, forming a cover-like frame structure. When worn, the main housing 110 and the earpiece assembly 200 cooperate with each other, and the elasticity or deformation of the connecting structure 120 achieves clamping and fixing to the user's ear.

[0116] This design utilizes the bending characteristics of the connecting structure 120 to allow the ear-clip headphones to fit snugly against the user's ear, thereby improving wearing stability and comfort. The clip-on structure effectively prevents the ear-clip headphones from slipping off during exercise or daily activities, making it suitable for usage scenarios requiring high-intensity wearing stability, such as sports and running. In addition, the bending connecting structure 120 also provides a certain degree of elastic cushioning, reducing pressure on the ears and avoiding discomfort caused by prolonged wear.

[0117] Meanwhile, the design of the curved connection structure 120 also provides greater freedom for adjusting the position of the earpiece assembly 200. By adjusting the relative position of the earpiece assembly 200 on the connection structure 120, users can flexibly adjust the clamping force and acoustic position of the earpiece according to the shape and size of their ears, achieving optimal wearing comfort and sound transmission performance. This structure can also be combined with the aforementioned positioning and guiding structures to ensure smooth adjustment and precise positioning.

[0118] Furthermore, the curved shape of the connecting structure 120 contributes to the compact and lightweight design of the overall ear clip-on headphones, making them easy to carry and store. In terms of materials, the connecting structure 120 can be made of engineering plastics or metal alloys with good elasticity and fatigue resistance to ensure the durability of the clamping force and the structural robustness.

[0119] In another embodiment, the earcup headphone 10 can be designed as a wired earcup headphone, in which case the cable 400 in the connection structure 120 can be connected to an external device via, for example, a 3.5mm plug. This design allows the earcup headphone to be compatible with a variety of audio devices, improving its ease of use and versatility. In the wired earcup headphone configuration, the earpiece assembly 200 can also be adjusted relative to the connection structure 120 so that the user can set it according to personal preference and wearing comfort.

[0120] It should be noted that the ear-clip headphones 10 typically include other components commonly found in existing ear-clip headphones, such as microphones, volume controls, and indicator lights. The configuration and functions of these components will be flexibly designed according to different ear-clip headphone types and user needs. No single limitation is made here to ensure the versatility and user-friendliness of the ear-clip headphones. Through the above design, the ear-clip headphones 10, whether wireless or wired, can provide a high-quality audio experience and convenient functionality, meeting the diverse needs of modern users.
