[0037] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] Existing ear-clip headphones typically utilize a fixed structural design, with the earpiece assembly fixedly connected to the main housing. This lacks flexible adjustment, resulting in insufficient wearing comfort and impacting listening quality. Specifically, the fixed position of the earpiece assembly in existing ear-clip headphone designs often makes it difficult for users to achieve optimal acoustic matching, thus affecting sound quality and wearing stability. This is especially true 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.

[0039] Based on this, see Figures 1 to 8 As shown, an embodiment of the present invention provides an ear-clip headset 10, which includes a host component 100 and an earpiece component 200; the host component 100 includes a host shell 110 and a connecting structure 120, one end of the connecting structure 120 is connected to the host shell 110; the earpiece component 200 is connected to the end of the connecting structure 120 away from the host shell 110, and the position of the earpiece component 200 relative to the connecting structure 120 is telescopically adjustable.

[0040] The ear clip 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 to be detachable and telescopically adjustable relative to the connection structure 120.

[0041] 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 ear canal depth, achieving a better acoustic match, 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 and reduces discomfort caused by improper earpiece positioning, resulting in a good user experience.

[0042] Specifically, the earpiece assembly 200 can be retracted and adjusted using a variety of methods, including sliding, rotating, or snapping. This allows users to select the appropriate earpiece assembly 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 1 mm, 2 mm, 3 mm, 5 mm, 10 mm, and other positions. The specific value can be adjusted based on actual design requirements to ensure that the wearing needs of different users are met while also preventing the connection structure from being too long, which could affect the overall stability and portability of the ear clip earphone. If the adjustment range is too narrow, some users may not be able to achieve the ideal matching of wearing comfort and sound quality. If the adjustment range is too wide, the structural complexity and manufacturing cost will increase, and the stability of the ear clip earphone may also be affected.

[0043] Furthermore, the ear-clip earphone 10 also includes a telescopic structure, which includes a telescopic part 1211 and a connecting hole 2112. The telescopic part 1211 can be adjustably inserted into the connecting hole 2112 and slidably cooperates with the connecting hole 2112; any one of the telescopic part 1211 and the connecting hole 2112 is provided on the connecting structure 120, and the other one of the telescopic part 1211 and the connecting hole 2112 is provided on the earpiece assembly 200.

[0044] First, the coordination between telescopic portion 1211 and connecting hole 2112 ensures a more stable and precise relative position between the two. The telescopic portion 1211 is inserted into connecting hole 2112, effectively limiting the radial and axial displacement of the earpiece assembly 200 along the telescopic portion 1211. This ensures reliable engagement of the snap-fitting portion of the positioning structure, enhancing the robustness and stability of the overall connection. Compared to relying solely on external snaps or clamps, this structural coordination method is more compact and structurally sound, avoiding unnecessary exposed components and improving the overall aesthetics of the product.

[0045] Secondly, the presence of connection hole 2112 allows earpiece assembly 200 to protect telescopic portion 1211. Specifically, connection hole 2112 surrounds a portion of connection structure 120, effectively preventing damage to connection structure 120 caused by external collisions, drops, or friction during use, such as bumps and scratches. This protection not only extends the service life of connection structure 120 but also reduces the risk of connection failure due to structural damage, thereby improving the overall durability and reliability of the earclip earphone.

[0046] Furthermore, the coordination between the telescopic portion 1211 and the connection hole 2112 enables a compact design. By embedding the telescopic portion 1211 within the connection hole 2112 of the earpiece assembly 200, the connection components are prevented from being exposed or expanding, reducing the overall assembly size and facilitating a thinner, more ergonomic earclip headphone design. This compact design is particularly important for portable electronic devices, effectively saving space and improving wearing comfort.

[0047] In practice, the size and shape of the connection hole 2112 and the clearance between it and the telescopic portion 1211 can be optimized based on actual needs. The size of the connection hole 2112 can be slightly larger than the telescopic portion 1211 to ensure smooth installation, while also cooperating with the raised and recessed portions of the positioning structure to achieve a secure connection.

[0048] See Figures 1 to 8 In the illustrated embodiment, the telescopic portion 1211 is provided on the connecting structure 120, and the connecting hole 2112 is located on the earpiece assembly 200. In this structure, the telescopic portion 1211 is inserted into the connecting hole 2112 and slidably engages with the connecting hole 2112, enabling the earpiece assembly 200 to be telescopically adjusted 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, and improving the secureness and comfort of wearing.

[0049] In other embodiments, the telescopic portion 1211 may also be provided on the earpiece assembly 200, with the telescopic portion 1211 extending 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 a sliding fit between the telescopic portion 1211 and the connecting hole 2112, thereby enabling positional adjustment between the earpiece assembly 200 and the connecting structure 120. The advantage of this structure is that the position of the telescopic portion and the connecting hole can be flexibly designed to suit the overall structural layout of the product, helping to optimize the overall appearance and internal space utilization of the earphones, while also facilitating personalized adjustments to meet the needs of different users.

[0050] It should be noted that both structural solutions ensure precise fit and smooth sliding between the telescopic portion 1211 and the connecting hole 2112, preventing the adjustment effect from being affected by loose or stuck connecting components. In specific implementations, the dimensions, tolerances, and surface treatment of the telescopic portion 1211 and the connecting hole 2112 can be optimized based on actual needs to balance ease of adjustment and secure connection.

[0051] Furthermore, in some embodiments, the main housing 110 and the connecting structure 120 may also be connected in an adjustable manner using a similar telescopic structure. Specifically, corresponding telescopic portions 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 headset structure, allowing users to adjust not only the position of the earpiece assembly 200 but also the relative position between the main housing 110 and the connecting structure 120 based on their ear shape and wearing habits, thereby achieving greater wearing comfort and stability.

[0052] By providing an adjustable telescopic structure between the main housing 110 and the connecting structure 120, the earphones can adapt to different head and ear shapes, improving the overall fit and user experience. This multi-level adjustment mechanism also helps achieve more precise acoustic matching, further optimizing sound transmission efficiency and sound quality.

[0053] To sum up, regardless of whether the telescopic part 1211 is arranged on the connecting structure 120 or the earpiece assembly 200, and whether a telescopic structure is arranged between the main body shell 110 and the connecting structure 120, flexible adjustment of the various connecting parts of the earphone can be achieved to meet the wearing needs of different users, improve wearing comfort and sound quality performance, and at the same time ensure the firmness of the connection and the compactness and beauty of the structure.

[0054] Specifically, the earpiece assembly 200 includes an earpiece housing 210 and a sound unit 220. The earpiece housing 210 includes a connecting section 211 and a housing structure 212, which can be integral or separate. In the case of an integral structure, the connecting section 211 and the housing structure 212 are formed through an integral molding process, resulting in a more compact structure and higher overall strength. This improves the durability and sealing of the earclip earphones and reduces the risk of internal components being affected by the external environment.

[0055] In some embodiments, the connecting section 211 and the shell structure 212 adopt a split structural design, which allows the two parts to be made of different materials. Specifically, the connecting section 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 section 211 and the connecting structure 120, and prevent the connecting section 211 from being damaged due to frequent assembly and disassembly or external forces. The shell structure 212 can be made of a lightweight material with good acoustic properties, such as ABS plastic or silicone material, to enhance wearing comfort and the sound quality of the sound unit 220. The split structural design can not only achieve optimal matching of material properties, but also facilitate separate replacement and maintenance, reduce maintenance costs, and improve the practicality and environmental protection of the product.

[0056] The connection hole 2112 is provided on the connection section 211, and the telescopic portion 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 taking advantage of the material of the connection section 211 to enhance the reliability and durability of the overall connection.

[0057] The sound unit 220 is installed inside the housing structure 212 and is responsible for converting the electrical signal transmitted from the host assembly 100 into a sound signal to achieve the audio playback function. The sound unit 220 is connected to the host assembly 100 via a cable 400 to achieve signal connection.

[0058] In one embodiment, the connecting section 211 extends at least partially toward the interior of the shell, and an end of the connecting section 211 facing the inner side of the shell structure 212 is provided with a receiving groove 2114 connected to the connecting hole 2112, and the receiving groove 2114 is used to accommodate the cable 400 between the earpiece assembly 200 and the host assembly 100.

[0059] First, the receiving groove 2114 provides a dedicated placement space for the cable 400, effectively positioning and protecting it within the connecting section 211. Guiding and constrained by the receiving groove 2114, the cable 400 maintains a more standardized routing, preventing it from swinging freely or being squeezed within the earclip headphone. This reduces the risk of damage from uneven force or friction, extending the cable's service life and overall signal transmission stability.

[0060] Secondly, the provision of the receiving groove 2114 makes the overall structure of the earpiece assembly 200 and the connecting structure 120 more compact. Without interfering with the routing of the cable 400, the connecting section 211, through its internal receiving groove, rationally arranges the cable layout, preventing it from being exposed or occupying additional space, thereby improving the volume efficiency and neatness of the earclip earphone. Especially with the trend towards lighter, thinner, and more compact earclip earphone designs, this structural design effectively balances functionality with aesthetics, meeting the requirements of ergonomics and user comfort.

[0061] Furthermore, the receiving slot 2114 facilitates the installation and maintenance of the cable 400. The cable can be guided to the desired location through the receiving slot, enabling quick and accurate assembly, reducing assembly difficulty and time costs. Furthermore, the presence of the receiving slot facilitates subsequent inspection, repair, or replacement of the cable, improving the maintainability and ease of use of the product.

[0062] Furthermore, the ear-clip earphone 10 also includes a guiding structure, which includes a guiding groove 2113 and a guiding portion 1214. Either the guiding groove 2113 or the guiding portion 1214 is provided on the telescopic portion 1211, and the other of the guiding groove 2113 and the guiding portion 1214 is provided on the earpiece assembly 200. The guiding portion 1214 slides with the guiding groove 2113, thereby significantly improving the adjustment smoothness and accuracy of the earpiece assembly 200.

[0063] Specifically, the guide structure is designed to provide more precise positioning and adjustment. The presence of guide groove 2113 effectively guides the movement of guide portion 1214, reducing any sticking or awkwardness caused by errors and ensuring flexibility and stability during adjustment. This sliding fit not only ensures smooth movement of earpiece assembly 200 but also enhances the user experience, making the earclip earphones more convenient to adapt to different wearing requirements.

[0064] In some embodiments, the guide structure can extend in a direction parallel to or at an angle to the axis of the connection hole 2112. This design not only optimizes the structural layout of the earcup earphone, but also prevents the earpiece assembly 200 from rotating with the connection structure 120, effectively limiting unnecessary rotation of the earcup earphone during use and enhancing the stability of the overall structure.

[0065] Furthermore, the design of the guide structure takes into account the needs of different usage scenarios. If the guide slot 2113 and guide portion 1214 are configured as a combination of multiple slots and components, specifically including two or more guide slots and guide portions, this provides more flexible adjustment, allowing users to make more precise adjustments based on their personal comfort and usage habits. The configuration of multiple guide slots and guide portions allows for a wider range of adjustment, accommodating different wearing angles and positions, further enhancing the user experience of ear clip headphones.

[0066] The material selection for the guide structure is also crucial. High-strength, low-friction materials, such as polytetrafluoroethylene (PTFE) or nylon, are recommended to ensure a smooth sliding fit and durability. These materials not only reduce wear and extend service life but also provide a degree of resistance to environmental factors that can affect the performance of ear clip headphones, such as temperature fluctuations and humidity.

[0067] In one embodiment, the connecting structure 120 includes a connecting member 121 and an anti-slip member 122, one end of the connecting member 121 is connected to the main body shell 110, and the other end of the connecting member 121 is passed through the connecting hole 2112, the anti-slip member 122 is detachably connected to the connecting member 121 and is located inside the earpiece assembly 200, and the outer peripheral edge 1221 of the anti-slip member 122 at least partially extends outward and is used to abut the earpiece assembly 200, for firmly contacting the earpiece assembly 200 to prevent the assembly from loosening or falling off during use.

[0068] In this embodiment, the anti-slip member 122 can be threadedly connected to the connecting member 121. This connection method not only simplifies the assembly process but also facilitates disassembly and maintenance when necessary, improving the convenience of using the earclip earphone. When the earpiece assembly 200 moves to the end of the path, the anti-slip member 122 can abut the open end surface 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 earclip earphone during use.

[0069] Specifically, the anti-slip member 122 can be a screw, and its outer peripheral edge 1221 is evenly distributed along the outer circumference of the anti-slip member 122. Such a design not only enhances the contact area between the anti-slip member 122 and the earpiece assembly 200, but also improves its tensile strength and shear resistance, ensuring that it is not easy to fall off or be damaged under the action of external forces. In addition, the number of the outer peripheral edges 1221 can be multiple, specifically can be set to two, three or more, and these outer peripheral edges 1221 are spaced along the outer circumference of the anti-slip member 122 to form a serrated structure. The design of this serrated structure can further enhance the gripping force of the anti-slip member 122 when it abuts the earpiece assembly 200, reduce the possibility of sliding, and thus improve the overall stability and durability of the ear clip type earphones.

[0070] Furthermore, the telescopic structure also includes a limiting flange 1212, which is provided on the telescopic portion 1211 and extends outward from the outer peripheral wall of the telescopic portion 1211. The limiting flange 1212 is located on the outside of the earpiece assembly 200, and the limiting flange 1212 is used to abut against the earpiece assembly 200.

[0071] In the above structure, the design of the limiting flange 1212 plays an important role in ensuring 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 portion 1211 and extends outward from the outer side of the telescopic portion 1211. When the earpiece assembly 200 moves to the extreme position along the telescopic path, it abuts against the outer wall of the earpiece assembly 200, thereby achieving positional limitation.

[0072] The main advantages of this retaining structure are: First, it effectively prevents the earpiece assembly 200 from detaching from the connecting structure 120 due to excessive adjustment, ensuring safe and stable adjustment. Second, the retaining flange 1212 prevents the earpiece assembly 200 from accidentally falling off during strenuous exercise or external forces, enhancing product durability and user confidence. Furthermore, because the retaining flange 1212 is located on the telescopic portion 1211, it has a simple structure, is easy to manufacture and assemble, and does not significantly increase the overall size of the earphone.

[0073] 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 prevent an overly tight or loose fit from affecting smooth adjustment. For example, the limiting flange 1212 can be designed with a certain elastic material or structural deformation zone to absorb minor errors or vibrations that may occur during the adjustment process, thereby further improving the smoothness of adjustment and the user experience.

[0074] In summary, the limiting flange 1212 provided on the telescopic portion 1211 provides effective motion limit protection by cooperating with the outer wall of the earpiece assembly 200, ensuring that the earpiece assembly moves safely and stably within the adjustment range, thereby improving the overall performance and reliability of the headset.

[0075] In one embodiment, the shell structure 212 is composed of a first shell 2121 and a second shell 2122, and the two are fastened together to form a complete shell structure 212. Specifically, the connecting section 211 can be provided on the first shell 2121, so as to achieve effective connection with the connecting structure 120. During the assembly process, the connecting member 121 can be inserted into the connecting section 211 from the opening at one end of the connecting hole 2112 away from the second shell 2122, and then the anti-slip member 122 is connected and fixed to the connecting member 121 from the side of the first shell 2121 toward the second shell 2122. This assembly method has a reasonable structure and a clear path, which not only ensures the stability of the connection structure, but also facilitates disassembly and maintenance, greatly improving the operational convenience of users and production lines.

[0076] The connection between the first shell 2121 and the second shell 2122 can be in various forms, including screw connection, snap connection, and magnetic connection. The screw connection method has a strong structure and is suitable for applications requiring high mechanical strength and durability. It can ensure a tight fit between the two shells and prevent loosening. The snap connection has a simple structure and is quick to disassemble and disassemble, making it suitable for product designs that frequently maintain or replace the sound unit 220. The magnetic connection method has the advantages of rapid adsorption and disassembly, improving assembly efficiency while achieving a good sealing effect and structural aesthetics.

[0077] Specifically, the anti-slip member 122 can also cover the opening of the receiving groove 2114, thereby effectively limiting the installation of the cable 400. By covering the opening of the receiving groove 2114 with the anti-slip member 122, the cable 400 can be prevented from sliding out of the receiving groove 2114 or shifting due to pulling or vibration during use, ensuring that the cable 400 always remains in the predetermined wiring position, thereby improving the cable's fixed reliability.

[0078] Furthermore, the anti-drop member 122 covering the opening of the receiving groove 2114 also provides protection, preventing the cable 400 from direct contact with external objects, reducing the risk of cable damage due to external forces, friction, or collisions, and improving the durability and service life of the cable. Furthermore, this structural design ensures neat cable routing, preventing a cluttered cable from affecting the overall appearance of the ear clip headphones and the user's wearing comfort.

[0079] The threaded connection between the anti-slip member 122 and the connector 121 allows the anti-slip member 122 to be securely fixed to the connector 121, effectively securing the cable 400 without affecting the adjustable function of the earpiece assembly 200. This design balances cable routing security with the overall structural flexibility of the earclip headphone, further enhancing the overall performance and user experience of the earclip headphone 10.

[0080] Specifically, the earcup 10 also includes a positioning structure, through which the earpiece assembly 200 is adjustably positioned and connected to the main body housing 110; the positioning structure includes a first positioning portion 1213 and a second positioning portion 2111, either of which is provided on the connecting structure 120, and the other of which is provided on the earpiece assembly 200, and the first positioning portion 1213 is detachably connected to the second positioning portion 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 intended to address problems such as loosening or falling off of the earpiece assembly 200 during adjustment and use, thereby improving the overall structural reliability and user experience of the earcup.

[0081] Specifically, one of the first positioning portion 1213 and the second positioning portion 2111 is located on the connecting structure 120, while the other is located on the earpiece assembly 200. The cooperation of these two positioning components achieves precise positioning and a secure connection of the earpiece assembly 200. This positioning structure not only allows for 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 preventing fluctuations in sound quality or discomfort caused by loosening of the earpiece during wear.

[0082] The connection between the first positioning portion 1213 and the second positioning portion 2111 in the positioning structure can be a snap-fit fit. This method has a simple structure, low manufacturing cost, and convenient operation, making it particularly suitable for quick disassembly and installation for user self-adjustment. The advantage of the snap-fit fit is that it can be disassembled and assembled without the need for additional tools, allowing users to flexibly adjust the position of the earpiece assembly 200 according to their needs, thereby enhancing personalization and comfort.

[0083] In some specific embodiments, the positions of the first positioning portion 1213 and the second positioning portion 2111 can be interchanged, that is, the first positioning portion 1213 can be arranged on the earpiece assembly 200, and the second positioning portion 2111 can be arranged on the connecting structure 120. This design provides more structural freedom, which is convenient for optimizing the component layout and adjustment method according to different ear clip headphone design schemes. It is not limited to a single fixed structure, thereby enhancing the flexibility and adaptability of the structural design.

[0084] In addition, the connection method between the first positioning portion 1213 and the second positioning portion 2111 is not limited to snap-fitting, and various methods such as magnetic connection, pin connection, threaded connection, and snap-fit connection can also be used. Magnetic connection facilitates quick disassembly and installation, improves user experience, and can reduce mechanical wear while ensuring a certain connection strength; pin connection provides higher mechanical strength and anti-falloff ability, which is suitable for occasions with higher requirements for firmness; threaded connection can achieve fine adjustment and firm fixation, which is suitable for designs that require higher positioning accuracy; snap-fit connection takes into account both convenient disassembly and stable connection. Furthermore, the number of the first positioning portion 1213 and / or the second positioning portion 2111 is multiple, and at least one first positioning portion 1213 snaps into engagement with at least one second positioning portion 2111. This multiple quantity setting not only enhances the stability of the positioning structure, but also can achieve more precise and multi-gear adjustment functions through the synergistic effect of multiple positioning components.

[0085] Specifically, the number of the first positioning portions 1213 and the second positioning portions 2111 can be two, three, or more, and is not limited here. By setting multiple first positioning portions 1213 and second positioning portions 2111, and designing multiple snap-fit points at their corresponding positions, the user can select different snap-fit positions according to actual needs, thereby achieving multi-level position adjustment of the earpiece assembly 200 relative to the connection structure 120. For example, three first positioning portions 1213 are provided on the connection structure 120, and three corresponding second positioning portions 2111 are provided on the earpiece assembly 200. The user can select any pair of them for snap-fitting, so that the earpiece assembly 200 can be switched among the three preset positions to meet the needs of different ear canal depths and wearing habits.

[0086] The preset adjustment positions not only enhance flexibility but also ensure ease of adjustment and precise positioning. Users can quickly adjust without complex manipulations. The secure snap-fit 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.

[0087] It can be understood that when there are multiple first positioning parts 1213 and second positioning parts 2111, the provision of multiple positioning components allows the positioning structure to disperse 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 such as exercise or long-term wear, multiple locking points can effectively resist external impact and vibration, reducing discomfort and sound quality fluctuations caused by looseness.

[0088] In one embodiment, there are multiple first positioning portions 1213, and the multiple first positioning portions 1213 are spaced apart along the extension direction of the connecting structure 120, wherein at least one first positioning portion 1213 engages with the second positioning portion 2111. Specifically, the number of first positioning portions 1213 can be two, three, four, or more, and the spacing can be flexibly determined based on actual design requirements. For example, it can be 1 mm, 2 mm, 3 mm, 5 mm, and other different values, which are not limited here. This multiple and spaced arrangement effectively provides multiple engagement options for the second positioning portion 2111, enabling multiple adjustment positions of the earpiece assembly 200 relative to the connecting structure 120.

[0089] Multiple first positioning portions 1213 are spaced apart along the extension direction of the connecting structure 120, ensuring more precise and stable snap-fitting. Users can select different positions of the first positioning portions 1213 to engage with the second positioning portions 2111 as needed, thereby adjusting the position of the earpiece assembly 200. This design not only meets the individual needs of different users for wearing depth and comfort, but also enhances flexibility and convenience in adjustment.

[0090] Furthermore, the arrangement of multiple first positioning portions 1213 in combination with corresponding second positioning portions 2111 forms a multi-point snap-fit connection, significantly enhancing the strength and stability of the connection between the connecting structure 120 and the earpiece assembly 200. This multi-point snap-fit connection disperses external force concentration, reducing the risk of excessive force at a single point, and preventing accidental separation of the earpiece assembly 200 due to external forces such as vibration, impact, or pulling during daily use, thereby enhancing the durability and safety of the overall structure.

[0091] In one embodiment, the first positioning portion 1213 is a raised structure, and the second positioning portion 2111 is at least partially a recessed structure, and the two are positioned and connected by a snap fit between the raised structure and the recessed structure. This structural fit has obvious advantages and can make the overall positioning structure more compact and stable.

[0092] Specifically, the second positioning portion 2111 can be designed as a recessed form, such as a groove or hole. A groove structure provides a longer contact surface for the connection, distributing force and improving connection strength and durability; a hole structure facilitates accurate positioning and rapid assembly, both of which are suitable for different design requirements. When the raised first positioning portion 1213 is inserted into the recessed second positioning portion 2111, a reliable mechanical connection is formed, preventing the connecting components from sliding relative to each other or falling off during use.

[0093] To further enhance the convenience and stability of the snap-fit, the outer surface of the first positioning portion 1213 is designed as a circular arc in a preferred embodiment. This arc allows the protrusion to smoothly guide into the recessed structure, reducing resistance and jamming during installation, allowing the user to quickly and accurately complete the snap-fit operation. Furthermore, the arc surface effectively alleviates stress concentration during snap-fit, reducing the risk of local material wear and deformation, thereby extending the service life of the positioning structure.

[0094] Furthermore, the combination of raised and recessed structures not only enhances the compactness of the connection but also strengthens the overall structure's resistance to vibration and impact. The multi-point protrusion and recessed snap-on design evenly distributes external forces, preventing damage caused by excessive force at a single point. This ensures a secure connection between the earpiece assembly 200 and the connecting structure 120 and reduces accidental separation due to vibration or external impact.

[0095] This design also offers the advantage of simplified manufacturing. The raised and recessed structures can be created through conventional processes such as injection molding, machining, or mold forming, facilitating mass production at a low cost. Based on specific product requirements, the size and shape of the raised portion of the first positioning portion 1213, as well as the depth and width of the recessed portion of the second positioning portion 2111, can be flexibly adjusted to achieve the optimal fit and user experience.

[0096] In another embodiment, the first positioning portion 1213 and the second positioning portion 2111 are connected by a damping connection to achieve a movable and adjustable positioning connection. A damping connection generally refers to a damping element or damping mechanism provided between two connecting parts, which provides a certain resistance through friction or elastic force, thereby achieving a connection effect that allows smooth movement while preventing position slippage during adjustment.

[0097] The advantage of using a damping connection is that it can provide the user with appropriate resistance feedback when adjusting the position of the earpiece assembly 200 relative to the connection structure 120, avoiding excessive looseness or unstable sliding during adjustment, and improving the adjustment accuracy and operational feel. At the same time, the damping connection can effectively prevent the earpiece assembly 200 from shifting due to vibration or shaking caused by external forces during wear, thereby enhancing wearing stability and comfort. This is particularly important for users who exercise or wear the earpiece for long periods of time, as it can ensure a stable sound transmission path and avoid fluctuations in sound quality.

[0098] The damping connection can be implemented in a variety of ways. For example, a spring can be combined with a friction surface, using an elastic element to apply a preload force to generate moderate friction between the first positioning portion 1213 and the second positioning portion 2111. Alternatively, elastic materials such as rubber rings and silicone pads can be used as damping media to provide cushioning and resistance. Furthermore, a damping mechanism with a gear or ratchet structure can be designed to achieve graded resistance adjustment through mechanical engagement to meet the adjustment force requirements of different users.

[0099] It should be noted that the resistance of the damping connection should be appropriately designed based on user adjustment convenience and wearing stability. Too little resistance may cause earpiece assembly 200 to loosen or slip during use, affecting wearing comfort and sound quality stability. Too much resistance may increase adjustment difficulty and reduce the user experience. The general resistance range can be achieved by adjusting parameters such as spring stiffness, friction surface material, and contact area. The specific value can be determined based on actual product design requirements.

[0100] Furthermore, the damping connection structure can be combined with other positioning methods (such as snap-fit, magnetic attraction, etc.) to further enhance positioning diversity and reliability. For example, the damping connection is used to achieve continuous and smooth adjustment, while the snap-fit structure is used to quickly locate multiple preset gears. The combination of the two can achieve both flexible adjustment and stable positioning.

[0101] Furthermore, the positioning structure is at least partially located in the connecting hole 2112 .

[0102] First, the protruding portion of connecting section 211 forms a larger contact surface with connector 121, effectively increasing the connection area between the two and significantly improving the connection strength. This larger contact surface helps distribute stress across the connection, reducing localized stress concentration and minimizing the risk of loosening between connector 121 and connecting section 211 due to friction or vibration, thereby ensuring the overall mechanical stability of the ear clip earphone.

[0103] Secondly, the connection hole 2112 is covered by the positioning structure, creating a covering between the earpiece assembly 200 and the connector 121, enhancing stability during relative movement between the two. This covering structure limits the irregular shaking and wiggling of the earpiece assembly 200 on the connecting structure 120, improving the smoothness of the adjustment process and positioning accuracy, allowing the wearer to more stably fix the earpiece position, ensuring good wearing comfort and stable acoustic performance.

[0104] Furthermore, the connection hole 2112, which is covered by the positioning structure, effectively provides dust protection. The covering acts as a physical barrier, preventing dust, dirt, and other small particles from entering the positioning structure. This prevents the accumulation of foreign matter from affecting the normal movement and engagement of the positioning structure, thereby extending the life of the ear clip earphones.

[0105] See Figure 7 and Figure 8As shown, in another embodiment, the ear-clip earphone 10 further includes a flexible positioning member 300, which is sleeved on the telescopic portion 1211 and located between the telescopic portion 1211 and the connecting hole 2112. By providing the flexible positioning member 300, it is closely matched with the telescopic portion 1211 and the connecting hole 2112, and the relative movement between the connecting structure 120 and the earpiece assembly 200 can be elastically limited.

[0106] Specifically, the flexible positioning member 300 is made of an elastic material such as a rubber ring or silicone ring. Leveraging its excellent elasticity and cushioning properties, it provides appropriate damping and resilience during the telescopic adjustment of the connection structure and the earpiece assembly. This design not only prevents mechanical shock and wear on the positioning structure caused by excessive adjustment, but also effectively prevents loosening and abnormal noise caused by vibration or external forces during use of the earpiece assembly 200, thereby improving wearing stability and comfort.

[0107] Furthermore, the flexible positioning element 300 absorbs some vibration and impact, reducing mechanically transmitted vibration noise, further optimizing the earphones' sound quality and wearing experience. Thanks to the excellent wear and aging resistance of the rubber and silicone rings, the positioning element 300 maintains its elasticity and position-locking properties even after extended use, extending the lifespan of the earphones.

[0108] To sum up, the flexible positioning member 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 earphone 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 earphone 10.

[0109] Furthermore, the telescopic portion 1211 may be provided with a mounting groove for cooperating with the positioning member 300. By providing a dedicated mounting groove on the telescopic portion 1211, the flexible positioning member 300 (such as a rubber ring or silicone ring) can be accurately embedded in the groove during installation, thereby fixing and positioning the positioning member and preventing it from shifting or slipping during use, thereby improving the convenience and stability of installation.

[0110] The fit between the mounting groove and the positioning member 300 not only facilitates quick and accurate installation of the positioning member by the assembler, reducing assembly time and process complexity, but also ensures that the positioning member 300 maintains a stable position within the earphone structure, maximizing its elastic limiting and cushioning functions. Specifically, the mounting groove can be designed as an annular groove or notch, with dimensions matching the cross-section of the positioning member 300 to achieve a tight fit.

[0111] Furthermore, the mounting slots help secure the positioning member 300 to the telescopic portion 1211, preventing displacement due to repeated movement during telescopic adjustment. This ensures that the positioning member remains in the desired position, effectively maintaining the stability and accuracy of the telescopic structure. This structural design also reduces friction between the positioning member and other structural components, reducing wear and tear and extending the service life of the positioning member and the entire headset.

[0112] In one embodiment, the earclip headphone 10 can be a wireless earclip headphone. In this case, the main unit assembly 100 typically includes a control module and a battery, both of which are located within the main unit housing 110. The control module communicates with the sound unit 220 of the earpiece assembly 200 via a cable 400 built into the connection structure 120. This arrangement enables the control module to receive wireless signals and drive the sound unit 220 to produce sound. The battery also provides the necessary power to the control module, ensuring the proper operation of the earclip headphone.

[0113] In the design of wireless ear clip headphones, the built-in cable 400 of the connection structure 120 not only performs signal transmission but also optimizes the overall structure of the ear clip headphones, making them more compact and easier to wear. Users can adjust the position of the earpiece assembly 200 on the connection structure 120 to optimize wearing comfort and acoustics based on their wearing habits. This flexible adjustment enhances the adaptability of the ear clip headphones and meets the personalized needs of different users.

[0114] Furthermore, the connecting structure 120 in the ear-clip earphone 10 employs a curved structure, such as a C- or U-shape. This curved structure allows the connecting structure 120 to connect to the main housing 110 and the earpiece assembly 200 at either end, forming an enveloping frame structure. When worn, the main housing 110 and the earpiece assembly 200 cooperate with each other, securing the ear to the user's ear through the elasticity or deformation of the connecting structure 120.

[0115] This design utilizes the curved nature of the connecting structure 120 to ensure the ear clip earphones fit snugly against the user's auricle, enhancing wearing stability and comfort. The clip-on structure effectively prevents the ear clip earphones from slipping during exercise or daily activities, making it ideal for use cases requiring high wearing stability, such as exercise and running. Furthermore, the curved connecting structure 120 provides a certain degree of elastic cushioning, alleviating pressure on the ear and preventing discomfort from prolonged wear.

[0116] The curved connecting structure 120 also provides greater flexibility in adjusting the position of the earpiece assembly 200. By adjusting the relative position of the earpiece assembly 200 on the connecting structure 120, users can flexibly adjust the clamping force and acoustic position of the earpiece based on the shape and size of their ears, achieving optimal wearing comfort and sound transmission. This structure can also be combined with the aforementioned positioning and guide structures to ensure smooth adjustment and precise positioning.

[0117] Furthermore, the curved shape of the connecting structure 120 contributes to the compact and lightweight design of the ear clip-on earphones, making them easy to carry and store. Regarding the material, the connecting structure 120 can be made of engineering plastics or metal alloys with good elasticity and fatigue resistance to ensure a long-lasting clamping force and structural durability.

[0118] In another embodiment, the earclip headphone 10 can be designed as a wired earclip headphone. In this case, the cable 400 in the connecting structure 120 can be connected to an external device via, for example, a 3.5mm plug. This design allows the earclip headphone to be compatible with a variety of audio devices, enhancing its convenience and versatility. In the wired earclip headphone configuration, the earpiece assembly 200 can also be adjusted relative to the connecting structure 120, allowing the user to configure it according to personal preference and wearing comfort.

[0119] It should be noted that the ear clip earphones 10 typically include other components commonly found in existing ear clip earphones, such as a microphone, volume control, and indicator lights. The configuration and functionality of these components can be flexibly designed based on the type of ear clip earphone and user needs. This is not a single limitation, ensuring the versatility and user-friendliness of the ear clip earphones. Through the above design, the ear clip earphones 10, whether wireless or wired, can provide a high-quality audio experience and convenient functionality, meeting the diverse needs of modern users.
