Abstract
Description
Technical Field
[0001] This utility model relates to the field of headphone technology, and in particular to a headphone. Background Technology
[0002] In the audio equipment field, wireless headphones have gradually replaced traditional wired headphones due to their convenience. Currently, the mainstream wireless headphones on the market are mainly divided into two categories: ear-hook headphones (the headphone body and ear hook are molded as one piece) and in-ear Bluetooth headphones without ear hooks. However, both of these structures have significant drawbacks in practical use:
[0003] Poor adaptability to different scenarios: Users need to frequently switch devices in different usage scenarios. For example, in sports scenarios, ear hooks are needed to secure the headphones and prevent them from falling off, while in non-sports scenarios, the rigid structure of the ear hooks can easily put pressure on the auricle, and users tend to choose Bluetooth headphones without ear hooks to reduce the feeling of restriction.
[0004] High usage costs: To meet the needs of multiple scenarios, users need to purchase two types of headphones at the same time, resulting in equipment redundancy and economic burden.
[0005] Disjointed experience: Frequent device switching requires re-pairing and adjustment of wearing method, affecting the continuity of use. Utility Model Content
[0006] Therefore, the purpose of this utility model is to provide an earphone to solve the problems mentioned above in the background art.
[0007] An earphone includes an ear hook and an earphone body detachably connected to the ear hook via a connecting assembly. The connecting assembly includes a positioning member extending to the end of the earphone body, a limiting portion elastically mounted at both ends of the positioning member, a positioning groove formed at the end of the ear hook, a driving portion disposed on both sides of the positioning groove, and a limiting groove. The positioning member and the positioning groove are inserted into each other. The limiting portion contacts the driving portion through an elastic member, so that the limiting portion is engaged with or disengaged from the limiting groove under the guidance of the driving portion.
[0008] Compared to existing technologies, the advantages of this application are as follows: This structure, through the insertion and engagement of the positioning component and the positioning groove, combined with the elastic locking mechanism of the limiting part and the limiting groove, enables quick assembly and disassembly of the earphone body and the ear hook. The dual-locking design not only ensures the reliability of the connection during exercise and effectively prevents accidental detachment caused by external forces, but also meets the needs of multiple usage scenarios through a modular structure, allowing for adaptation to various scenarios without the need to replace different earphones, significantly reducing usage costs and improving the continuity of the experience.
[0009] Furthermore, the positioning member and the ear hook are respectively provided with connection holes at their ends away from the headphone body, and the connection holes remain exposed whether the headphone body and the ear hook are connected or separated.
[0010] Furthermore, guide grooves are provided on both sides of the drive unit, and guide plates are connected to both sides of the drive unit. The guide plates are adapted to the guide grooves so that the drive unit is limited to moving on the ear hook.
[0011] Furthermore, the ear hook is provided with weight-reducing holes.
[0012] Furthermore, the ear hook is made of shape memory alloy, and its curvature is adapted to the contour of the ear.
[0013] Furthermore, the positioning element and the positioning groove have rectangular cross-sections.
[0014] Furthermore, the limiting part is a hemispherical or wedge-shaped protrusion structure, and its outer surface is provided with anti-slip texture.
[0015] Furthermore, the elastic element is a compression spring or elastic arm structure, with its two ends connected to the inner wall of the positioning element and the limiting part, respectively. Attached Figure Description

Detailed Implementation
[0023] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.
[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] Please see Figures 1 to 5 The image shows an earphone according to an embodiment of the present invention, including an ear hook 10 and an earphone body 30 detachably connected to the ear hook 10 via a connecting component 20. The connecting component 20 includes a positioning member 21 extending to the end of the earphone body 30, a limiting part 22 elastically mounted at both ends of the positioning member 21, a positioning groove 23 formed at the end of the ear hook 10, a driving part 24 disposed on both sides of the positioning groove 23, and a limiting groove 25. The positioning member 21 and the positioning groove 23 form an insertion engagement, and the limiting part 22 contacts and engages with the driving part 24 through an elastic member 26, so that the limiting part 22, guided by the driving part 24, engages or disengages from the limiting groove 25.
[0027] When the headphones are not in use (or when the ear hook 10 causes pressure on the ear), the user can trigger the disassembly mechanism by pressing the drive unit 24: the drive unit 24 squeezes the limiting part 22 to move it away from the limiting groove 25, while compressing the elastic member 26. At this time, the limiting part 22 disengages from the limiting groove 25, releasing the limiting constraint on the positioning member 21, and the user can then pull the positioning member 21 out of the positioning groove 23 to use the headphone body 30 alone. This design allows the headphones to work independently in scenarios where the ear hook 10 is not needed, avoiding discomfort caused by prolonged wear.
[0028] When the ear hook 10 needs to be installed, the user can trigger the assembly process by pressing the limiting part 22: after being squeezed by external force, the limiting part 22 retracts into the groove where the elastic element 26 is placed, and at the same time, the elastic element 26 is compressed and stores energy. Then, the limiting part is aligned and inserted into the positioning groove 23. After reaching the predetermined position, the elastic element 26 releases the stored elastic potential energy, pushing the limiting part 22 to reset and lock into the limiting groove 25, thereby achieving precise locking between the positioning element 21 and the positioning groove 23, thus completing the stable installation of the ear hook 10.
[0029] This structure, through the insertion and engagement of the positioning component 21 and the positioning groove 23, combined with the elastic locking mechanism of the limiting part 22 and the limiting groove 25, enables quick assembly and disassembly of the earphone body 30 and the ear hook 10. The dual-locking design ensures reliable connection during exercise, effectively preventing accidental detachment due to external forces. Furthermore, the modular structure meets the needs of multiple usage scenarios, allowing for adaptation to both sports and non-sports scenarios without the need to replace different earphones, significantly reducing usage costs and improving user experience consistency. The synergistic effect of the drive part 24 and the elastic component 26 simplifies complex mechanical operations into intuitive plugging and unplugging actions. Users only need to apply pressure in one direction to switch connection states, greatly improving operational convenience and human-computer interaction efficiency.
[0030] Furthermore, the positioning member 21 and the ear hook 10 are respectively provided with connection holes 31 at their ends away from the headphone body 30. The connection holes 31 remain exposed whether the headphone body 30 is connected to or separated from the ear hook 10. The exposed connection holes 31 in both connected and separated states allow users to easily perform additional functions on the headphone body 30 (such as hanging ornaments, earrings, etc.) in both states, enhancing the product's versatility and flexibility.
[0031] Please see Figure 6 Furthermore, guide grooves 27 are provided on both sides of the drive unit 24, and guide plates 28 are connected to both sides of the drive unit 24. The guide plates 28 are adapted to the guide grooves 27 so that the drive unit 24 is limited to move on the ear hook 10. The cooperation between the guide grooves 27 and the guide plates 28 limits the movement trajectory of the drive unit 24, ensuring that the drive unit 24 moves only in a preset direction during operation, avoiding jamming or wear problems caused by skew or misalignment, and improving the service life and reliability of the connecting assembly 20.
[0032] Furthermore, the ear hook 10 is provided with weight-reducing holes 11. The weight-reducing holes 11 effectively reduce the overall weight of the ear hook 10, reduce the pressure felt by the user when wearing it, and at the same time enhance the structural strength of the ear hook 10 by optimizing the material distribution, thus achieving a balance between lightweight and durability.
[0033] In this embodiment, the ear hook 10 is made of shape memory alloy, and its curvature is adapted to the contour of the ear. The ear hook 10 made of shape memory alloy can adapt to the shape of different users' ear, providing a personalized fit, and has good deformation recovery ability. It is not easily deformed after long-term use, thus improving wearing comfort and stability.
[0034] Specifically, the positioning member 21 and the positioning groove 23 have rectangular cross-sections. The rectangular cross-section design of the positioning member 21 and the positioning groove 23 increases the insertion contact area, improves the anti-torsion performance, and prevents the headphone body 30 from rotating or shifting due to external forces during wearing, thus ensuring the accuracy of the audio output direction.
[0035] Specifically, the limiting part 22 is a hemispherical or wedge-shaped protrusion structure, and its outer surface is provided with anti-slip texture. The hemispherical or wedge-shaped protrusion of the limiting part 22, combined with the anti-slip texture, reduces the frictional resistance when in contact with the limiting groove 25, and increases the coefficient of friction through the texture, preventing accidental disengagement due to a smooth surface and enhancing the reliability of the engagement.
[0036] Optionally, the elastic element 26 is a compression spring or an elastic arm structure, with its two ends connected to the inner wall of the positioning element 21 and the limiting part 22, respectively. In this embodiment, the elastic element 26 is a compression spring.
[0037] In summary, in the above embodiments of this utility model, when the headphones are used in a non-exercise state (or when the ear hook 10 causes pressure on the auricle), the user can trigger the disassembly mechanism by pressing the drive unit 24: the drive unit 24 squeezes the limiting part 22 to move it away from the limiting groove 25, while compressing the elastic member 26. At this time, the limiting part 22 disengages from the limiting groove 25, releasing the limiting constraint on the positioning member 21, and the user can then pull the positioning member 21 out of the positioning groove 23 to use the headphone body 30 alone. This design allows the headphones to work independently in scenarios where the ear hook 10 is not needed, avoiding discomfort caused by long-term wear.
[0038] When the ear hook 10 needs to be installed, the user can trigger the assembly process by pressing the limiting part 22: after being squeezed by external force, the limiting part 22 retracts into the groove where the elastic element 26 is placed, and at the same time, the elastic element 26 is compressed and stores energy. Then, the limiting part is aligned and inserted into the positioning groove 23. After reaching the predetermined position, the elastic element 26 releases the stored elastic potential energy, pushing the limiting part 22 to reset and lock into the limiting groove 25, thereby achieving precise locking between the positioning element 21 and the positioning groove 23, thus completing the stable installation of the ear hook 10.
[0039] This structure, through the insertion and engagement of the positioning component 21 and the positioning groove 23, combined with the elastic locking mechanism of the limiting part 22 and the limiting groove 25, enables quick assembly and disassembly of the earphone body 30 and the ear hook 10. The dual-locking design ensures reliable connection during exercise, effectively preventing accidental detachment due to external forces. Furthermore, the modular structure meets the needs of multiple usage scenarios, allowing for adaptation to both sports and non-sports scenarios without the need to replace different earphones, significantly reducing usage costs and improving user experience consistency. The synergistic effect of the drive part 24 and the elastic component 26 simplifies complex mechanical operations into intuitive plugging and unplugging actions. Users only need to apply pressure in one direction to switch connection states, greatly improving operational convenience and human-computer interaction efficiency.
