Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a headphone that is comfortable to wear. Background Technology

[0002] Headphones are worn on the user's ears and can transmit audio signals directly or indirectly to the user's cochlea in the form of vibrations, so that the user can perceive the audio output by the headphones.

[0003] Currently, there are headphones where the sound unit and battery are integrated. The sound unit of these headphones is relatively heavy, which puts a lot of pressure on the ears and makes them uncomfortable to wear. In addition, there are headphones where the sound unit and battery are separate and connected to the two ends of the ear hook. When wearing headphones with this structure, the battery is located behind the ear and is blocked by the ear, which is not conducive to heat dissipation. Utility Model Content

[0004] This invention provides a pair of headphones that are comfortable to wear, thereby improving wearing comfort and heat dissipation of the battery section.

[0005] This utility model provides a comfortable-to-wear earphone, which includes a sound-generating part, a battery part, a connecting component, and an ear hook part. One end of the battery part is connected to the sound-generating part along a first direction, and the other end is provided with an ear hook connecting cavity. The battery part forms a first through hole communicating with the ear hook connecting cavity, and the first through hole extends along the first direction. The connecting component is disposed in the ear hook connecting cavity. One end of the ear hook part extends into the ear hook connecting cavity through the first through hole and is connected to the battery part through the connecting component.

[0006] Furthermore, the ear hook is configured to be rotatable relative to the battery portion about a first central axis extending in the first direction and a second central axis extending in the second direction, the first direction and the second direction intersecting each other.

[0007] Furthermore, when worn, the sound-emitting part is located inside the user's ear canal, and the battery part fits against the skin between the user's auricular foot and the top of the outer auricular helix.

[0008] Furthermore, the dimension of the battery portion along the first direction is greater than or equal to 37 mm and less than or equal to 40 mm, and the maximum dimension of the battery portion along a third direction intersecting both the first and second directions is greater than or equal to 10 mm and less than or equal to 11 mm. Furthermore, the inner wall of the ear hook connecting cavity is provided with a connecting shaft, the second central shaft being the central shaft of the connecting shaft. The connecting assembly includes a main body portion connected to the ear hook portion, the main body portion forming a first connecting hole, and the main body portion being sleeved onto the connecting shaft through the first connecting hole, allowing the ear hook portion to rotate around the connecting shaft with the main body portion.

[0009] Furthermore, the connecting assembly also includes a first limiting structure connected to the main body, and a second limiting structure is formed on the inner wall of the ear hook connecting cavity opposite to the first through hole along the first direction. The first limiting structure and the second limiting structure can interact with each other so that the main body is limited to at least two set angles during rotation around the connecting shaft.

[0010] Furthermore, the first limiting structure and the second limiting structure elastically abut against each other.

[0011] Furthermore, the first limiting structure includes a spring pin connected to the main body, and the second limiting structure includes a plurality of limiting grooves formed on the inner wall of the ear hook connecting cavity. The plurality of limiting grooves are arranged in an arc around the connecting shaft. During the rotation of the main body around the connecting shaft, the spring pin head of the spring pin is successively limited to each of the limiting grooves.

[0012] Furthermore, the spring needle head includes a convex arc-shaped surface, and the groove wall of the limiting groove is a concave arc-shaped surface that cooperates with the convex arc-shaped surface.

[0013] Furthermore, the main body portion has a connecting groove and / or a connecting protrusion surrounding the first central axis, and one end of the ear loop portion has a connecting protrusion and / or a connecting groove surrounding the first central axis. The connecting protrusion and the connecting groove are engaged, allowing the ear loop portion to rotate around the first central axis.

[0014] Furthermore, an elastic damping ring is provided in the connecting groove, and the opposite sides of the elastic damping ring elastically abut against the wall surface of the main body and the wall surface of the ear hook part, respectively.

[0015] Furthermore, of the main body and the ear loop, one has an arc-shaped limiting groove extending around the first central axis, and the other has a limiting block. The limiting block and the arc-shaped limiting groove are slidably engaged. The two opposite ends of the arc-shaped limiting groove along its extension direction are limiting portions that restrict the sliding range of the limiting block, so that the ear loop rotates back and forth around the first central axis between a first rotation angle and a second rotation angle.

[0016] Furthermore, the outer surface of the main body is configured as a spherical surface, and the intersection point of the first central axis and the second central axis coincides with the center of the spherical surface.

[0017] This invention provides a comfortable pair of headphones, comprising a sound-generating part, a battery part, a connecting component, and an ear hook part. One end of the battery part is connected to the sound-generating part along a first direction, and the other end has an ear hook connecting cavity, within which the connecting component is located. One end of the ear hook part extends into the ear hook connecting cavity through a first through hole and is connected to the battery part via the connecting component. The separate arrangement of the sound-generating part and battery part in this invention results in a more balanced weight distribution, reducing ear pressure and improving wearing comfort. Furthermore, the battery part is located between the sound-generating part and the ear hook part. In the wearing state, the ear hook part is located behind the ear, and the battery part is located in front of the ear, providing a larger heat dissipation space in front of the ear, thus improving the heat dissipation effect of the battery part. Therefore, the headphones provided by this invention not only improve wearing comfort but also enhance the heat dissipation effect of the battery part. Attached Figure Description

Detailed Implementation

[0030] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0031] 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 application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0034] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0035] With the increasing popularity of audio output devices and the growing frequency of people using headphones and other devices, there are currently headphones where the sound unit and battery are integrated. The sound unit of this type of headphone is relatively heavy, which puts a lot of pressure on the ears and is uncomfortable to wear. In addition, there are headphones where the sound unit and battery are separated and connected to the two ends of the ear hook. When wearing this type of headphone, the battery is located behind the ear and is blocked by the ear, which is not conducive to heat dissipation.

[0036] Therefore, this application provides a comfortable pair of headphones, which includes a sound-generating part, a battery part, a connecting component, and an ear hook part. One end of the battery part is connected to the sound-generating part along a first direction, and the other end has an ear hook connecting cavity, in which the connecting component is disposed. One end of the ear hook part extends into the ear hook connecting cavity through a first through hole and is connected to the battery part through the connecting component. This design separates the sound-generating part and the battery part, resulting in a more balanced weight distribution, reducing ear pressure, and thus improving wearing comfort. Furthermore, the battery part is located between the sound-generating part and the ear hook part. In the wearing state, part of the ear hook part is located behind the ear, and the battery part is located in front of the ear. The heat dissipation space in front of the ear is relatively large, thus the heat dissipation effect of the battery part is good. Therefore, the headphones provided by this utility model not only improve wearing comfort but also enhance the heat dissipation effect of the battery part.

[0037] Below, refer to Figures 1 to 10 Some embodiments of this application will be described in detail.

[0038] Figure 1 A schematic diagram illustrating how the headphones are worn according to some embodiments of this application; Figure 2 A structural schematic diagram of an earphone with the cover removed, provided in some embodiments of this application; Figure 3 This application provides schematic diagrams of the structure of headphones according to some embodiments; Figure 4 Another structural schematic diagram of the earphone with the cover hidden, provided in some embodiments of this application; Figure 5 An exploded view of the earphone with the cover hidden, provided in some embodiments of this application; Figure 6 Cross-sectional views of headphones provided in some embodiments of this application; Figure 7 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 8 A cross-sectional view of the headphone connection assembly provided in some embodiments of this application; Figure 9 A schematic diagram of the structure of the main body of the earphone provided in some embodiments of this application; Figure 10 This is a partial structural diagram of the ear hook portion of an earphone provided in some embodiments of this application.

[0039] 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 10 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 2 to 8As 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.

[0040] like Figures 1 to 8 As shown, this application provides a comfortable-to-wear earphone, including a sound-emitting part 4, a battery part 1, a connecting component 2, and an ear hook part 3. One end of the battery part 1 along a first direction X is connected to the sound-emitting part 4, and the other end is provided with an ear hook connecting cavity 11. The battery part 1 forms a first through hole 12 communicating with the ear hook connecting cavity 11, and the first through hole 12 extends along the first direction X. The connecting component 2 is disposed in the ear hook connecting cavity 11. One end of the ear hook part 3 extends into the ear hook connecting cavity 11 through the first through hole 12 and is connected to the battery part 1 through the connecting component 2.

[0041] The sound-generating part 4 and the battery part 1 are separately designed, resulting in a more balanced weight distribution, reducing ear pressure and improving wearing comfort. Furthermore, the battery part 1 is located between the sound-generating part 4 and the ear hook part 3. When worn, the ear hook part 3 hangs on the ear, with part of it located behind the ear and part in front. The battery part 1 is located in front of the ear, where there is a larger heat dissipation space, thus improving the heat dissipation effect of the battery part 1. Therefore, the headphones provided by this invention not only improve wearing comfort but also enhance the heat dissipation effect of the battery part 1.

[0042] In some embodiments of this application, the ear loop portion 3 is configured to be rotatable relative to the battery portion 1 about a first central axis a extending along a first direction X and a second central axis b extending along a second direction Y, respectively, with the first direction X and the second direction Y intersecting.

[0043] like Figure 4 As shown, Figure 4 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.

[0044] For example, such as Figure 1 As shown, the sound-producing part 4 can be an in-ear type or a semi-in-ear type.

[0045] 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 battery compartment 1. The connecting component 2 is located inside the battery compartment 1, effectively isolating it from external impacts, sweat corrosion, and other risks, significantly improving the durability of the headphones.

[0046] In some embodiments of this application, such as Figure 1 As shown, when worn, the sound-emitting part 4 is located inside the user's ear canal, and the battery part 1 is attached to the skin between the user's auricular foot 100 and the top of the outer auricular helix 200.

[0047] This wearing method not only improves wearing comfort, but also allows users to adjust the battery unit 1 to a more snug and stable position against the ear by rotating the ear hook 3 during exercise or other activities. This enhances the stability of the earphone's fit and significantly reduces the risk of it falling out, ensuring stable use in various scenarios. Furthermore, the battery unit 1 fits snugly against the skin between the user's ear helix 100 and outer ear helix 200, allowing the ear hook 3 to wrap around the ear from the top and clamp firmly between the ear and head, preventing it from slipping off and further improving wearing stability.

[0048] In some embodiments of this application, the battery section 1 has a dimension along the first direction X that is greater than or equal to 37 mm and less than or equal to 40 mm, and a maximum dimension along the third direction Z, which intersects both the first and second directions Y, that is greater than or equal to 10 mm and less than or equal to 11 mm. This size of earphone results in a compact overall size, conforms to ergonomic design, and enhances wearing comfort.

[0049] For example, the size of the battery section 1 along the first direction X can be, but is not limited to, 37 mm, 37.5 mm, 38 mm, 38.5 mm, 39 mm, 39.5 mm, or 40 mm. The maximum size of the battery section 1 along the third direction Z can be, but is not limited to, 10 mm, 10.1 mm, 10.2 mm, 10.3 mm, 10.4 mm, 10.5 mm, 10.6 mm, 10.7 mm, 10.8 mm, 10.9 mm, or 11 mm.

[0050] In some embodiments of this application, such as Figures 2 to 6As 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.

[0051] 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.

[0052] 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.

[0053] In some embodiments of this application, such as Figures 2 to 6 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.

[0054] 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.

[0055] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the first limiting structure 22 and the second limiting structure 14 are elastically abutting against each other.

[0056] 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.

[0057] In some embodiments of this application, such as Figures 2 to 6 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] In the embodiments of this application, "multiple" means two or more.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] In some embodiments of this application, such as Figures 2 to 8 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.

[0066] 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.

[0067] In some embodiments of this application, such as Figures 4 to 10 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.

[0068] 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.

[0069] 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.

[0070] In some embodiments of this application, such as Figures 5 to 8 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.

[0071] The elastic damping ring 214 can be, but is not limited to, a rubber ring.

[0072] 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.

[0073] In some embodiments of this application, such as Figures 7 to 10 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] In some embodiments of this application, such as Figures 4 to 9 As 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.

[0078] The spherical surface 5 requires less space during rotation, reducing its footprint and thus the size of the headphone housing, which is beneficial for headphone miniaturization. The spherical surface 5 ensures that the intersection 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.

[0079] 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.

[0080] The connector 23 can be, but is not limited to, a bolt.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] In some embodiments of this application, the end of the ear loop 3 that connects to the battery part 1 can be made of, but is not limited to, polypropylene and polyethylene materials.

[0085] In some embodiments of this application, such as Figures 2 to 6 As shown, the headphones include a battery assembly 6, which is located inside the battery section 1 and provides power to the headphones.

[0086] In some embodiments of this application, the battery section includes a bottom shell 17 and a cover shell 16. The cover shell 16 covers the bottom shell 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.
