[0002] In recent years, with the popularization of portable electronic devices, especially smartphones and tablets, headphones, as one of the important accessories of these devices, have continued to grow in market demand.

[0003] Among the existing earphone designs, ear-hook earphones are favored by many users due to their stability and comfort. This type of earphone usually has a slidable sliding arm on the wearing body, and then the ear-hook is installed on the sliding arm. The sliding arm slides on the wearing body to drive the ear-hook to move, so as to adjust the fit between the earphone and the user's ear. However, when the earphones in the prior art are used for a long time or the position of the ear-hook is adjusted frequently, there is a lot of hard material friction between the connection position of the ear-hook and the sliding arm, which often leads to problems such as wear of components, abnormal noise and even damage. Utility Model Content

[0004] The main purpose of the utility model is to provide an earphone, aiming to solve the technical problems of the earphone in the prior art, such as easy wear of parts and abnormal noise in the process of moving the ear hanging parts.

[0005] To achieve the above-mentioned purpose, the earphones proposed in the utility model include a wearing body, a sliding arm, an ear hook and a fastener, the sliding arm can be slidably arranged on the wearing body, the sliding arm includes a mounting portion exposed outside the wearing body; the ear hook is formed with a mounting hole; the fastener includes a fastening portion and an abutting portion connected to each other, the fastening portion passes through the mounting hole and is fixedly connected to the mounting portion, the abutting portion is located on the side of the mounting hole that is away from the mounting portion, and the abutting portion abuts against the ear hook through an elastic gasket.

[0006] Optionally, the mounting portion includes a mounting tube, the mounting tube is inserted into the mounting hole, and the fastening portion is fixedly connected to the mounting tube.

[0007] Optionally, the mounting portion includes a mounting end surface, the mounting tube protrudes from the mounting end surface, and the mounting end surface abuts against an end wall of the mounting hole via a friction plate.

[0008] Optionally, the friction plate is arranged around the mounting tube.

[0009] Optionally, a limit block is convexly provided on the mounting end surface, a receiving groove is provided on the end wall of the mounting hole corresponding to the position of the limit block, the limit block is arranged in the receiving groove, and the position on the friction plate corresponding to the limit block is hollowed out.

[0010] Optionally, an inner circumferential wall of the mounting tube is provided with an internal threaded portion, and an outer circumferential wall of the fastening portion is provided with an external threaded portion, and the internal threaded portion is threadedly connected to the external threaded portion.

[0011] Optionally, a wiring cavity is provided on the sliding arm, the mounting tube is connected to the wiring cavity, the fastener is provided with a wiring hole passing through the fastening portion and the abutting portion, the wiring hole is connected to the inner cavity of the ear hook, and the electrical connection wire of the wearing body is routed to the inner cavity of the ear hook through the wiring cavity, the mounting tube and the wiring hole.

[0012] Optionally, a partial structure of the elastic gasket is clamped between the abutment portion and an end portion of the mounting tube close to the abutment portion.

[0013] The earphones of the utility model have the following advantages:

[0014] The elastic gasket is located between the abutment part of the fastener and the ear hook. This design innovation effectively reduces the direct hard material contact between the fastener and the ear hook. The elastic gasket, as a buffer medium, can significantly reduce the wear caused by the direct hard contact between the fastener and the ear hook. During the daily use of the earphones, especially when the position is frequently adjusted or worn, the elastic gasket can absorb and disperse the force generated by friction, thereby protecting the contact surface of the ear hook and the fastener from damage and extending the service life of the earphones.

[0015] In addition, the elastic gasket can effectively reduce the noise generated during the contact between the ear hook and the fastener. In the design without elastic gaskets, the direct contact of metal or hard plastic parts often produces unpleasant friction sounds when moving, which is a big disturbance for users who pursue high-quality hearing experience. The use of elastic gaskets greatly reduces this noise through the inherent sound insulation properties of its materials, allowing users to enjoy a quieter use environment even when adjusting the position of the headphones.

[0016] Furthermore, the introduction of the elastic gasket also enhances the overall structural stability of the earphone. By adding an elastic medium between the fastener and the ear hook, the fastener can effectively avoid potential damage or deformation of the ear hook caused by long-term use or external force, especially when the ear hook is made of hard plastic or other fragile materials. This design not only improves the durability of the earphone, but also ensures that the earphone can maintain stable performance even during strenuous exercise or changes in the external environment.

[0017] Finally, the elastic gasket can also provide a certain waterproof and dustproof effect. Since the elastic gasket can fit tightly into the gap between the fastener and the ear hook, it blocks the intrusion of moisture and dust to a certain extent, and plays a positive role in improving the service life and reliability of the headphones in various environments. This protective effect is of great significance for users who often use headphones outdoors or in dusty environments. BRIEF DESCRIPTION OF THE DRAWINGS

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0031] The utility model provides an earphone.

[0032] In the embodiment of the present utility model, Figures 1 to 6 As shown, the earphone includes a wearing body 1, a sliding arm 2, an ear hook 3 and a fastener 4, the sliding arm 2 is slidably provided on the wearing body 1, the sliding arm 2 includes a mounting portion 21 exposed outside the wearing body 1; the ear hook 3 is formed with a mounting hole 31; the fastener 4 includes a fastening portion 41 and abutting portion 42 connected to each other, the fastening portion 41 passes through the mounting hole 31 and is fixedly connected to the mounting portion 21, the abutting portion 42 is located on the side of the mounting hole 31 facing away from the mounting portion 21, and the abutting portion 42 abuts against the ear hook 3 through an elastic gasket 5.

[0033] It can be understood that the elastic gasket 5 is located between the abutment portion 42 of the fastener 4 and the ear hook 3. This design innovation effectively reduces the direct hard material contact between the fastener 4 and the ear hook 3. The elastic gasket 5, as a buffer medium, can significantly reduce the wear caused by the direct hard contact between the fastener 4 and the ear hook 3. During the daily use of the earphone, especially when the position is frequently adjusted or worn, the elastic gasket 5 can absorb and disperse the force generated by friction, thereby protecting the contact surface of the ear hook 3 and the fastener 4 from damage, thereby extending the service life of the earphone.

[0034] In addition, the elastic gasket 5 can also effectively reduce the noise generated during the contact between the ear hook 3 and the fastener 4. In the design without the elastic gasket 5, the direct contact of metal or hard plastic parts often produces unpleasant friction sounds when moving, which is a major disturbance for users who pursue high-quality hearing experience. The use of the elastic gasket 5 greatly reduces this noise through the inherent sound insulation properties of its material, so that users can enjoy a quieter use environment even when adjusting the position of the earphones.

[0035] Furthermore, the introduction of the elastic gasket 5 also enhances the overall structural stability of the earphone. By adding an elastic medium between the fastener 4 and the ear hook 3, the fastener 4 can effectively avoid potential damage or deformation of the ear hook 3 caused by long-term use or external force, which is particularly important when the ear hook 3 is made of hard plastic or other fragile materials. This design not only improves the durability of the earphone, but also ensures that the earphone can maintain stable performance even during intense exercise or changes in the external environment.

[0036] Finally, the elastic gasket 5 can also provide a certain waterproof and dustproof effect. Since the elastic gasket 5 can fit tightly into the gap between the fastener 4 and the ear hook 3, it blocks the invasion of moisture and dust to a certain extent, which plays a positive role in improving the service life and reliability of the earphones in various environments. This protective effect is of great significance for users who often use earphones outdoors or in dusty environments.

[0037] In specific implementation, there are many ways of detachable connection between the fastener 4 and the mounting portion 21, such as threaded connection, snap connection, latch connection, magnetic adsorption, etc., which are not specifically limited here.

[0038] The material of the elastic gasket 5 can be a synthetic material with good elasticity and wear resistance, such as silicone, rubber, polyurethane, etc.

[0039] The mounting portion 21 includes a mounting tube 211 . The mounting tube 211 is inserted into the mounting hole 31 . The fastening portion 41 is fixedly connected to the mounting tube 211 .

[0040] It is not difficult to understand that mutual limitation is achieved through the cooperation between the mounting tube 211 and the mounting hole 31, ensuring the precise alignment of the subsequent fastener 4 during the assembly process, reducing assembly errors, improving the efficiency and quality of earphone assembly, and providing convenience for the fixation of the subsequent fastener 4. The presence of the mounting tube 211 also provides a reinforcement effect for the hole wall of the mounting hole 31.

[0041] The mounting portion 21 includes a mounting end surface 212 , the mounting tube 211 protrudes from the mounting end surface 212 , and the mounting end surface 212 abuts against an end wall of the mounting hole 31 through a friction plate 6 .

[0042] It is not difficult to understand that the presence of the friction plate 6 reduces the friction contact between the sliding arm 2 and the ear hook 3, thereby extending the service life of the earphone components. At the same time, it also provides additional protection for the daily use of the earphone, ensuring the stable performance of the earphone during frequent adjustments or long-term use.

[0043] Since the friction plate 6 can be replaced as an independent component, the maintenance of the earphone is simpler and more economical.

[0044] In a specific implementation, the friction plate 6 may be made of rubber, silicone, polytetrafluoroethylene (PTFE), nylon, etc. These materials have good wear resistance and flexibility.

[0045] The friction plate 6 is arranged around the mounting tube 211. The friction plate 6 is arranged around the mounting tube 211, which has the main beneficial effect of ensuring uniform distribution of pressure and friction in the entire contact area, thereby improving the stability and durability of the connection.

[0046] A limit block 213 is protruding from the mounting end surface 212, a receiving groove 32 is provided on the end wall of the mounting hole 31 at a position corresponding to the limit block 213, the limit block 213 is arranged in the receiving groove 32, and the position on the friction plate 6 corresponding to the limit block 213 is hollowed out.

[0047] It is not difficult to understand that when assembling the earphones, the cooperation between the limit block 213 and the receiving groove 32 can accurately determine the position of the component, thereby avoiding installation errors, ensuring that the various parts of the earphones fit tightly, enhancing the overall structural stability of the earphones, and also simplifying the assembly process and improving assembly efficiency.

[0048] Since the mounting tube 211 is a cylinder, when the limiting block 213 is not provided, the friction plate 6 is easy to move in the circumferential direction of the mounting tube 211. In order to avoid this phenomenon, the limiting block 213 is designed.

[0049] An internal thread portion is disposed on the inner peripheral wall of the installation tube 211 , and an external thread portion is disposed on the outer peripheral wall of the fastening portion 41 . The internal thread portion is threadedly connected to the external thread portion.

[0050] The threaded connection method not only ensures the stability and durability of the connection, allowing the earphones to resist forces and vibrations from all directions and not easily loosen during use, but also provides convenience for maintenance and replacement of parts, because users or maintenance personnel can easily remove and reinstall relevant parts of the earphones by rotating the fastener 4. In addition, the threaded connection method allows fine-tuning of the tightness of the connection, which helps to achieve personalized adjustment of the wearing comfort of the earphones, thereby improving the user experience.

[0051] The sliding arm 2 is provided with a wiring cavity 22, the mounting tube 211 is connected to the wiring cavity 22, the fastener 4 is provided with a wiring hole 43 passing through the fastening portion 41 and the abutment portion 42, the wiring hole 43 is connected to the inner cavity of the ear hook 3, and the electrical connection line of the wearing body 1 is routed to the inner cavity of the ear hook 3 through the wiring cavity 22, the mounting tube 211 and the wiring hole 43.

[0052] The wiring cavity 22 is provided in the sliding arm 2, and the installation tube 211 is connected to the wiring cavity 22, and the wiring hole 43 provided in the fastener 4 is directly connected to the inner cavity of the ear hook 3. In addition to improving the protection of the wire and the aesthetics of the earphone, it also greatly promotes the miniaturization design of the earphone product. This internal direct wiring method avoids the need for the wire to bypass the connection position between the sliding arm 2 and the ear hook 3, reduces the additional space required on the outside of the earphone, and makes the earphone design more compact and lightweight.

[0053] A portion of the elastic gasket 5 is clamped between the abutting portion 42 and an end portion of the mounting tube 211 close to the abutting portion 42 .

[0054] This configuration allows the elastic gasket 5 to form a buffer layer between the fastener 4 and the mounting tube 211, effectively absorbing and dispersing the vibration and impact force generated during use, reducing direct hard contact between components, reducing wear, and thus extending the service life of the earphone. At the same time, the clamping design of the elastic gasket 5 also improves the adaptability of the earphone to changes in the external environment (such as temperature and humidity changes), maintains the safety and stability of the internal components of the earphone, and provides users with a more reliable and comfortable use experience.

[0055] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
