[0031] With the widespread use of audio output devices and the increasing frequency of people's use of headphones and other devices, ear-hook headphones have become an indispensable part of daily life. Currently, the connecting component between the ear hook and the headphone shell, which allows the ear hook to rotate, is usually located outside the headphone shell. This makes the headphone susceptible to damage from external forces, affecting its lifespan.

[0032] Therefore, this application provides an earphone, which includes an earphone shell, a connecting component, and an ear hook. The earphone shell has an ear hook connecting cavity, and the connecting component is disposed within the ear hook connecting cavity. One end of the ear hook extends into the ear hook connecting cavity through a first through hole and is connected to the earphone shell through the connecting component. The ear hook is configured to rotate relative to the earphone shell around a first central axis extending in a first direction and a second central axis extending in a second direction, respectively, with the first and second directions intersecting. The earphone provided by this utility model, by disposing of the connecting component inside the earphone shell, makes the connecting component less susceptible to damage from direct exposure to the external environment of the earphone shell, reducing damage caused by bumps, dust, or sweat during daily use, improving the durability and reliability of the earphone, and extending its service life.

[0033] Below, refer to Figures 1 to 9 Some embodiments of this application will be described in detail.

[0034] Figure 1 A structural schematic diagram of an earphone with the cover removed, provided in some embodiments of this application; Figure 2 This application provides schematic diagrams of the structure of headphones according to some embodiments; Figure 3 Another structural schematic diagram of the earphone with the cover hidden, provided in some embodiments of this application; Figure 4 An exploded view of the earphone with the cover hidden, provided in some embodiments of this application; Figure 5 Cross-sectional views of headphones provided in some embodiments of this application; Figure 6 A schematic diagram of the structure of the main body of the earphone and the elastic damping ring provided in some embodiments of this application; Figure 7 A cross-sectional view of the headphone connection assembly provided in some embodiments of this application; Figure 8 A schematic diagram of the structure of the main body of the earphone provided in some embodiments of this application; Figure 9 This is a partial structural diagram of the ear hook portion of an earphone provided in some embodiments of this application.

[0035] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined. These three directions intersect each other; here, intersecting each other includes perpendicularly intersecting each other. For ease of understanding of the embodiments of this application, in... Figure 1 and Figure 9 In the illustrated embodiment, an example is given where the first and second directions intersect perpendicularly. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where the two directions intersect perpendicularly. For ease of explanation, as follows... Figures 1 to 8 As shown by the arrows in the diagram, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction.

[0036] like Figures 1 to 7 As shown, this application provides an earphone, including an earphone shell 1, a connecting component 2, and an ear hook portion 3. The earphone shell 1 has an ear hook connecting cavity 11 and a first through hole 12 communicating with the ear hook connecting cavity 11, the first through hole 12 extending along a first direction X; the connecting component 2 is disposed in the ear hook connecting cavity 11; one end of the ear hook portion 3 extends into the ear hook connecting cavity 11 through the first through hole 12 and is connected to the earphone shell 1 through the connecting component 2, the ear hook portion 3 is configured to be able to rotate relative to the earphone shell 1 about a first central axis a extending along the first direction X and a second central axis b extending along the second direction Y, the first direction X and the second direction Y intersect.

[0037] like Figure 3 As shown, Figure 3 The dotted line 'a' represents the first central axis, and the dotted line 'b' represents the second central axis. It can be understood that the first central axis 'a' and the second central axis 'b' are both virtual axes, used to represent the rotation central axes of the ear hook 3 around two directions. The extension direction of the first central axis 'a' is consistent with the first direction X, and the extension direction of the second central axis 'b' is consistent with the second direction Y. Since the first direction X and the second direction Y intersect, the extension directions of the first central axis 'a' and the second central axis 'b' are different. That is, the ear hook 3 can rotate around two different rotation central axes, thereby adjusting the rotation angle of the ear hook 3 in two directions, so that the ear hook 3 can adapt to different ear shapes and wearing habits.

[0038] The ear hook 3 can rotate around a first central axis a extending along the first direction X and a second central axis b extending along the second direction Y, with the two axes intersecting. Users can freely adjust the rotation angle of the ear hook to adapt to different ear shapes and wearing habits, improving wearing comfort and stability. Through rotation adjustment, the headphone's sound hole can be more accurately aligned with the user's ear canal, reducing sound loss and interference during transmission, improving sound transmission efficiency, and significantly enhancing sound quality, allowing users to enjoy a clearer and more realistic audio experience. The engagement of the ear hook connecting cavity 11 with the first through hole 12 allows one end of the ear hook 3 to extend into the headphone shell 1. The connecting component 2 is located inside the headphone shell 1, effectively isolating it from external impacts, sweat corrosion, and other risks, significantly improving the durability of the headphones.

[0039] In some embodiments of this application, such as Figures 1 to 5 As shown, the inner wall of the ear hook connecting cavity 11 is provided with a connecting shaft 13, and the second central shaft b is the central shaft of the connecting shaft 13. The connecting assembly 2 includes a main body 21 connected to the ear hook part 3. The main body 21 has a first connecting hole 211. The main body 21 is sleeved on the connecting shaft 13 through the first connecting hole 211, so that the ear hook part 3 can rotate around the connecting shaft 13 with the main body 21.

[0040] It is understandable that the second central axis b is the central axis of the connecting shaft 13. Therefore, when the main body 21 rotates around the connecting shaft 13, it also rotates around the second central axis b.

[0041] The connecting shaft 13, located within the ear hook connecting cavity 11, serves as the connection point. The first connecting hole 211 of the main body 21 is fitted onto this shaft, forming a stable rotational connection between the connecting shaft 13 and the main body 21. This prevents the ear hook 3 from shifting or wobbling when rotating around the second central axis b, effectively improving structural reliability. By directly bearing the rotational function through the connecting shaft 13, mechanical complexity is reduced, the structure is simplified, and this contributes to improved production efficiency and a lower failure rate.

[0042] In some embodiments of this application, such as Figures 1 to 5 As shown, the connecting component 2 also includes a first limiting structure 22 connected to the main body 21. The inner wall of the ear hook connecting cavity 11 opposite to the first through hole 12 along the first direction X is formed with a second limiting structure 14. The first limiting structure 22 and the second limiting structure 14 can interact with each other so that the main body 21 is limited to at least two set angles during the rotation of the connecting shaft 13.

[0043] The cooperation of the first limiting structure 22 and the second limiting structure 14 can limit the rotation range of the ear hook 3 to at least two set angles, so that the ear hook can be adjusted between at least two set angles when rotating around the second central axis b. Users can easily adjust the angle to suit different ear shapes and wearing habits, thereby improving the comfort and stability of wearing.

[0044] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the first limiting structure 22 and the second limiting structure 14 are elastically abutting against each other.

[0045] The two elements elastically abut against each other, allowing relative movement between the first limiting structure 22 and the second limiting structure 14 when subjected to external force, thus adjusting the angle of the ear hook. Furthermore, after the angle is adjusted, the friction between them acts as a damping force, maintaining the adjusted angle and enabling adjustment of the ear hook at multiple angles. Additionally, the elastic abutment reduces deformation or wear of components caused by rigid contact, making it particularly suitable for scenarios requiring frequent adjustments.

[0046] In some embodiments of this application, such as Figures 1 to 5 As shown, the first limiting structure 22 includes a spring pin 221 connected to the main body 21, and the second limiting structure 14 includes a plurality of limiting grooves 15 formed on the inner wall of the ear hook connecting cavity 11. The plurality of limiting grooves 15 are arranged in an arc around the connecting shaft 13. During the rotation of the main body 21 around the connecting shaft 13, the spring pin head 222 of the spring pin 221 is limited to each of the limiting grooves 15 one by one.

[0047] The spring needle 221 refers to a needle-shaped component with elastic function, and the spring needle head 222 of the spring needle 221 elastically abuts against the groove wall of the limiting groove 15.

[0048] For example, multiple limiting grooves 15 are arranged in an arc around the connecting shaft 13 and connected in sequence. This makes the angles that the ear hook part 3 can be positioned relatively close together. That is, the angle difference between adjacent positions of the ear hook part 3 is relatively small, and the angle adjustment is more precise.

[0049] For example, multiple limiting grooves 15 are arranged in an arc around the connecting shaft 13 and spaced apart sequentially. This makes the positioning angle of the ear hook 3 relatively dispersed, that is, the angle difference between adjacent positions of the ear hook 3 is relatively large, and the adjustment range of the position is large. It can be understood that each time the spring pin 221 abuts against a limiting groove 15, the position limited by the limiting groove 15 corresponds to a set angle. The arrangement of multiple limiting grooves 15 allows the main body 21 to be limited to multiple different set angles, thereby giving the ear hook 3 multiple different adjustable positions.

[0050] In the embodiments of this application, "multiple" means two or more.

[0051] The spring pin 221 abuts against the arc-shaped limiting grooves 15 one by one, thus limiting the main body 21 to multiple different set angles, thereby realizing the adjustment of the ear hook part 3 around the second central axis b between multiple positions. The limiting grooves 15 are arc-shaped distributed along the connecting shaft 13, so that the elastic abutment force between the spring pin 221 and each limiting groove 15 is relatively uniform, which allows the spring pin 221 to better cooperate and position with each limiting groove 15, improving the reliability of positioning. In addition, the force felt by the hand during adjustment is relatively uniform, making the adjustment of the position more convenient and comfortable.

[0052] For example, when the spring pin 221 starts from one of the limiting grooves 15 and rotates to the other adjacent limiting groove 15, the ear hook part 3 rotates 15 degrees around the second central axis b.

[0053] For example, the spring pin 221 rotates through all the limiting grooves 15, that is, starting from one of the two limiting grooves 15 with the farthest distance between the two ends of the second limiting structure 14, it rotates through all the limiting grooves 15 until it reaches the other of the two limiting grooves 15 with the farthest distance between the two ends of the second limiting structure 14, and the ear hook part 3 rotates around the second central axis by no less than 60 degrees.

[0054] In some embodiments of this application, such as Figures 1 to 7 As shown, the spring needle head 222 includes a convex arc surface 223, and the groove wall of the limiting groove 15 is a concave arc surface 224 that cooperates with the convex arc surface 223.

[0055] The convex arc-shaped surface 223 of the spring tip 222 fits tightly against the concave arc-shaped surface 224 of the limiting groove 15, thereby increasing the contact area between them, reducing local pressure, and minimizing deformation or breakage of the spring tip 222 or the limiting groove 15 due to stress concentration after long-term use. The arc-shaped surface fit reduces frictional resistance, making the spring tip 222 switch more smoothly between multiple limiting grooves 15, eliminating the feeling of jamming, and improving the smoothness of adjustment.

[0056] In some embodiments of this application, such as Figures 3 to 9 As shown, the main body 21 has a connecting groove 212 and / or a connecting protrusion 213 surrounding the first central axis a, and one end of the ear loop 3 has a connecting protrusion 213 and / or a connecting groove 212 surrounding the first central axis a. The connecting protrusion 213 and the connecting groove 212 are engaged, so that the ear loop 3 can rotate around the first central axis a.

[0057] For example, the main body 21 has a connecting groove 212 surrounding the first central axis a, and one end of the ear loop 3 has a connecting protrusion 213 surrounding the first central axis a. The connecting protrusion 213 engages with the connecting groove 212, allowing the ear loop 3 to rotate relative to the main body 21 around the first central axis a.

[0058] For example, the main body 21 has both a connecting groove 212 and a connecting protrusion 213 surrounding the first central axis a. One end of the ear loop portion 3 has both a connecting protrusion 213 and a connecting groove 212 surrounding the first central axis a. The connecting groove 212 of the main body 21 and the connecting protrusion 213 of the ear loop portion 3 are engaged, allowing the ear loop portion 3 to rotate relative to the main body 21 around the first central axis a. The engagement structure of the connecting protrusion 213 and the connecting groove 212 enables the ear loop portion 3 to rotate relative to the main body 21 around the first central axis a, thereby achieving the function of adjusting the angle of the ear loop portion around the first central axis.

[0059] In some embodiments of this application, such as Figures 4 to 7 As shown, an elastic damping ring 214 is provided in the connecting groove 212, and the opposite sides of the elastic damping ring 214 elastically abut against the wall surface of the main body 21 and the wall surface of the ear hook 3, respectively.

[0060] The elastic damping ring 214 can be, but is not limited to, a rubber ring.

[0061] The elastic damping ring 214 provides damping for the ear hook 3 as it rotates around the first central axis a by elastically contacting the walls of the main body 21 and the ear hook 3, respectively, thereby achieving the positioning of the rotation angle. That is, when the ear hook 3 rotates around the first central axis a under the action of an external force, within the maximum rotation range, the damping force provided by the elastic damping ring 214 between the main body 21 and the ear hook 3 allows the ear hook 3 to be positioned at the angle it would be at when the external force driving its rotation is removed, thus adjusting the ear hook 3 to a suitable angle. Furthermore, the elastic contact of the elastic damping ring 214 continuously applies pressure to the main body 21 and the ear hook 3, preventing the ear hook 3 from rotating due to inertia under vibration or motion, ensuring stable wearing. The elastic damping ring 214 provides uniform frictional resistance through deformation, reducing inaccuracies in angle adjustment caused by excessively smooth rotation.

[0062] In some embodiments of this application, such as Figures 6 to 9 As shown, of the main body 21 and the ear loop 3, one has an arc-shaped limiting groove 215 extending around the first central axis, and the other has a limiting block 33. The limiting block 33 and the arc-shaped limiting groove 215 are slidably engaged. The two ends of the arc-shaped limiting groove 215 along its extension direction are limiting parts 216 that limit the sliding range of the limiting block 33, so that the ear loop 3 reciprocates around the first central axis a between the first rotation angle and the second rotation angle.

[0063] For example, when the ear hook part 3 rotates from the first rotation angle to the second rotation angle, or when the ear hook part 3 rotates from the second rotation angle to the first rotation angle, the angle of rotation of the ear hook part 3 around the first central axis a is not less than 30 degrees.

[0064] The ear hook 3 rotates around the first central axis a between the first rotation angle and the second rotation angle through the cooperating arc-shaped limiting groove 215 and the limiting block 33. It can be understood that the first rotation angle and the second rotation angle are the maximum range of adjustable angles. During the reciprocating rotation of the ear hook 3 between the first rotation angle and the second rotation angle, due to the damping effect provided by the elastic damping ring 214, the ear hook 3 can be positioned at any angle between the first rotation angle and the second rotation angle.

[0065] The cooperation between the arc-shaped limiting groove 215 and the limiting block 33 enables the ear hook part 3 to rotate around the first central axis a between the first rotation angle and the second rotation angle, limiting the maximum range of the rotation angle of the ear hook part 3 and reducing the probability of affecting the angle adjustment speed due to the inclusion of many unsuitable angles in the rotation angle.

[0066] In some embodiments of this application, such as Figures 3 to 8As shown, the outer surface of the main body 21 is configured as a spherical surface 5, and the intersection point of the first central axis a and the second central axis b coincides with the center of the spherical surface 5.

[0067] The spherical surface 5 requires less space during rotation, reducing space occupation and allowing for a smaller headphone shell, which is beneficial for headphone miniaturization. The spherical surface 5 ensures that the intersection of the rotation of the first central axis a and the second central axis b coincides with the center of the sphere, resulting in a uniform torque distribution during rotation and reducing wear caused by eccentric forces.

[0068] In some embodiments of this application, the main body 21 has a cavity inside. The main body 21 has a second connecting hole 217 and a third connecting hole 218 at its two ends in the first direction X. The second connecting hole 217 is closer to the first through hole 12 than the third connecting hole 218, and is connected to the ear loop part 3 via a connector 23. The connector 23 can rotate synchronously with the ear loop part 3 as it rotates around the first central axis a. The third connecting hole 218 is connected to the first limiting structure 22. The second connecting hole 217, the third connecting hole 218, and the first connecting hole 211 all communicate with the cavity of the main body 21.

[0069] The connector 23 can be, but is not limited to, a bolt.

[0070] In some embodiments of this application, the end of the ear loop 3 connected to the main body 21 has a fourth connecting hole 34. The connector 23 enters the fourth connecting hole 34 through the second connecting hole 217. At this time, one end of the connector 23 (e.g., the head of a bolt) is confined in the cavity of the main body 21. The remaining part of the connector 23 (e.g., the shank of a bolt) passes through the second connecting hole 217 and extends into the fourth connecting hole 34 and is fixed to the fourth connecting hole 34, thereby connecting the ear loop 3 to the main body 21. When the ear loop 3 rotates, the connector 23 rotates synchronously with the ear loop 3 relative to the main body.

[0071] In some embodiments of this application, the second connecting hole 217 shares a central axis with the connecting groove 212 and / or connecting protrusion 213 of the main body 21, and the fourth connecting hole 34 shares a central axis with the connecting groove 212 and / or connecting protrusion 213 of the ear hook 3.

[0072] In some embodiments of this application, the surface of the ear loop 3 that comes into contact with the user's skin is made of silicone.

[0073] In some embodiments of this application, the end of the ear hook 3 that connects to the earphone shell 1 can be made of, but is not limited to, polypropylene and polyethylene materials.

[0074] In some embodiments of this application, such as Figures 1 to 5 As shown, the headphones include a battery assembly 6, which is located inside the headphone shell 1 and provides power to the headphones.

[0075] In some embodiments of this application, the earphone shell includes a shell bottom 17 and a shell cover 16. The shell cover 16 covers the shell bottom 17 to form a circuit receiving cavity 18 and an ear hook connecting cavity 11. The battery assembly 6 and the sound generating unit 7 are disposed within the circuit receiving cavity 18. The circuit receiving cavity 18 is located on the side of the ear hook connecting cavity 11 away from the first through hole 12, and the circuit receiving cavity 18 and the ear hook connecting cavity 11 are arranged adjacent to each other. A second limiting structure 14 is formed in the partition wall between the circuit receiving cavity 18 and the ear hook connecting cavity 11.

[0076] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
