Description

Technical Field

[0001] This application relates to the field of smart wearable product technology, specifically to an earphone and an earphone assembly. Background Technology

[0002] Ear-hook headphones are headphones with an added auxiliary suspension device to help users hang the headphones on the outside of their ears. Ear-hook headphones are widely popular due to their ease of wear and high comfort during extended periods of use.

[0003] Ear-hook headphones consist of an ear cup, an ear hook, and an ear hook end connected in sequence. The ear hook hangs on the user's ear, the ear cup is located in front of the ear, corresponding to the concha, and the ear hook end is located behind the ear. Because different users have different angles between their auricle and head, the current ear hook end is difficult to adapt to different angles, resulting in an ill-fitting fit and a poor user experience. Utility Model Content

[0004] This application provides an earphone and an earphone assembly. The ear hook of the earphone is adjustable in position, providing a high degree of fit and a better user experience.

[0005] In a first aspect, embodiments of this application provide an earphone, which includes an earcup, an ear hook, and an ear hook end. The ear hook includes a first end and a second end opposite to each other, the earcup is connected to the first end, the second end has a central axis and extends along the central axis, and the ear hook end is rotatably connected to the second end about the central axis, and the ear hook end has a non-centrally symmetrical structure relative to the central axis.

[0006] In this application, because the ear hook end rotates around the central axis to connect to the second end of the ear hook, and the ear hook end has a non-centrally symmetrical structure relative to the central axis, its own posture changes and its relative position to the second end changes when it rotates relative to the second end. For example, the tilt angle or orientation of the ear hook end relative to the second end may change, or the relative position of a certain surface or area of ​​the ear hook end to the second end may change. Therefore, when a user wears headphones, they can adjust the posture of the ear hook end by rotating it, allowing it to rotate to a suitable position for a good fit against the user's head and the back of the ear, improving the fit and providing a better user experience.

[0007] In some possible implementations, the ear hook end has an inner cavity and a mounting hole, the mounting hole connecting the inner cavity to the external space of the ear hook end, and the second end is inserted into the mounting hole.

[0008] In this implementation, since the second end of the ear hook is inserted into the mounting hole at the end of the ear hook, the end of the ear hook wraps around and protects the second end of the ear hook, which helps to reduce the risk of damage to the second end of the ear hook and improves the structural reliability of the headphones.

[0009] In some possible implementations, the wall of the mounting hole includes a first surface and a second surface, which are arranged opposite to each other and spaced apart along the axial direction of the mounting hole. The ear hook includes a limiting block located at the second end, which is engaged between the first surface and the second surface.

[0010] In this implementation, the first surface of the ear hook end can limit the second end of the ear hook by restricting it with a limiting block, preventing the second end of the ear hook from detaching from the ear hook end; the second surface of the ear hook end can also limit the second end of the ear hook by restricting it with a limiting block, preventing the second end of the ear hook from overextending into the ear hook end. Therefore, the ear hook end, through the joint restriction of the limiting block by the first and second surfaces, improves the assembly accuracy and connection reliability between the second end of the ear hook and the ear hook end.

[0011] In some possible implementations, the ear hook end includes a housing and a mating component, with the mating component fixed to the inside of the housing. A mounting hole and an inner cavity are located on opposite sides of the mating component. A first surface is located on the housing, and a second surface is located on the mating component.

[0012] In this implementation, the first and second surfaces of the ear hook end are respectively set on the housing and the mating part. Then, the limiting block is limited by the assembly structure of the housing and the mating part. This not only reduces the structural processing difficulty of the ear hook end, but also helps to reduce the assembly difficulty of the headphones.

[0013] In some possible implementations, the wall of the mounting hole further includes a third and a fourth surface, which are arranged opposite each other and spaced apart along the circumference of the mounting hole, with a limiting block located between the third and fourth surfaces. Specifically, when the end of the ear loop rotates relative to the second end, the limiting block moves between the third and fourth surfaces.

[0014] In this implementation, the ear hook end is limited by the third and fourth surfaces to restrict the movement of the limiting block in the circumferential direction, thereby limiting the relative rotation angle between the second end of the ear hook and the ear hook end. This prevents the relative rotation angle from being too large and damaging the internal connecting parts (such as wires) of the ear hook and the ear hook end, thus improving the reliability of the headphones.

[0015] For example, by adjusting the distance between the third and fourth surfaces in the circumferential direction of the mounting hole, and / or adjusting the width of the limiting block in the circumferential direction of the mounting hole, the range of rotation angles of the ear hook end relative to the second end of the ear hook can be adjusted.

[0016] In some possible implementations, multiple movable slots are formed between the third and fourth surfaces, and these slots are arranged at intervals along the circumference of the mounting holes. Multiple limiting blocks are also present, each corresponding to one of the multiple movable slots.

[0017] In this implementation, the ear hook end and the second end of the ear hook are connected by multiple movable slots and multiple limiting blocks, thereby limiting the two in multiple places in the circumferential direction around the central axis, making the limiting structure of the two more stable and reliable.

[0018] In some possible implementations, the ear hook end includes a housing and a mating component, with the mating component fixed to the inside of the housing. A mounting hole and an inner cavity are located on opposite sides of the mating component. Alternatively, the first and third surfaces are located on the housing, and the second and fourth surfaces are located on the mating component; or, the first surface is located on the housing, and the second, third, and fourth surfaces are located on the mating component; or, the first, third, and fourth surfaces are located on the housing, and the second surface is located on the mating component.

[0019] In this implementation, the ear hook end has some of the structures from the first to the fourth surface set on the shell and some of the structures set on the mating parts. Then, the limiting block is limited by the assembly structure of the shell and the mating parts. This not only reduces the structural processing difficulty of the ear hook end, but also helps to reduce the assembly difficulty of the headphones.

[0020] In some possible implementations, the ear hook end includes a housing and a mating part, with the mating part fixed to the inside of the housing, and the mounting hole and the inner cavity located on both sides of the mating part, respectively.

[0021] The housing includes a sleeve, a first protrusion, and a second protrusion. The sleeve is arranged around the mounting hole. The first protrusion and the second protrusion are both protruding from the inner wall surface of the sleeve. The first surface is located on the side surface of the first protrusion facing the inner cavity, the second protrusion is located on the side surface of the first protrusion facing the inner cavity, and the third surface is located on the side surface of the second protrusion close to the first surface.

[0022] The mating parts include a plate and a protrusion. A sleeve is fixedly connected to the periphery of the plate. The second surface is located on the plate. The protrusion protrudes from the plate and is located inside the sleeve. One end of the protrusion abuts against the surface of the second protrusion away from the third surface, and the other end of the protrusion forms a fourth surface.

[0023] In this implementation, by setting the self-structure and mating structure of the shell and the mating parts, the processing difficulty of the ear hook end and the assembly difficulty with the second end of the ear hook are reduced, which is conducive to improving the production yield of the headphones.

[0024] In some possible implementations, the ear hook includes a connector, a cover, and a wire. The connector, at least partially located at the second end, is a rigid structural member. One end of the wire connects to the ear cup, and the other end passes through the connector and extends into the inner cavity. The wire provides a conductive connection between devices within the ear cup and devices at the end of the ear hook. The cover, a flexible structural member, covers the connector and the wire, separating the connector from the wall of the mounting hole.

[0025] In this implementation, the second end of the ear hook is secured to the wire by a rigid connector, ensuring a stable connection between the wire and the ear hook end. A flexible covering material encapsulates the connector and wire, providing cushioning and protection, thus enhancing the structural reliability of the second end of the ear hook. The covering material can be, but is not limited to, a soft rubber material.

[0026] In some possible implementations, the ear hook also includes a sealing ring located at the second end. The sealing ring surrounds the cover and is fixed to the circumferential side of the cover, with an interference fit between the sealing ring and the wall of the mounting hole. In this implementation, the sealing ring enables a sealed connection between the second end and the end of the ear hook, providing waterproofing and dustproofing to improve the reliability of the headphones. Furthermore, the sealing ring also provides damping during relative rotation between the second end and the end of the ear hook, resulting in a better user experience when rotating the end of the ear hook.

[0027] Damping can be controlled by adjusting the interference between the sealing ring and the wall of the mounting hole, such as by adjusting the protrusion height of the sealing ring, thereby controlling the force required for the user to rotate the end of the ear loop.

[0028] In some possible implementations, the sealing ring and the covering are integrally formed structural components. In this case, the connection structure between the sealing ring and the covering is stable and reliable, and the manufacturing process is relatively simple.

[0029] In some possible implementations, at least two sealing rings are used, spaced apart along the central axis. In this case, multiple sealing rings provide better sealing between the second end and the final end of the ear hook, and offer greater flexibility in damping adjustment.

[0030] In some possible implementations, the ear hook also includes a reinforcing wire. The reinforcing wire is stiffer than the conductor and also stiffer than the sheath. The reinforcing wire is located inside the sheath and one end is connected to the connector. In this case, the reinforcing wire increases the structural stiffness of the ear hook, allowing the earphone to be stably suspended by the ear hook, resulting in better wearing stability. The reinforcing wire can be, but is not limited to, at least one metal wire.

[0031] In some possible implementations, the headphones also include an elastic element connecting the second end to the ear hook end. When the ear hook end rotates relative to the second end, the elastic element deforms. In this implementation, when a user wears the headphones, the ear hook end can be rotated at an angle, and then, under the elastic force of the elastic element, the ear hook end can automatically conform to the back of the user's ear and head, maintaining a stable fit after conforming. This improves the ease of wearing, fit, and stability of the headphones.

[0032] In some possible implementations, the elastic element is a torsion spring, with the centerline of the helical spring body parallel to the central axis. The first torsion arm of the torsion spring is inserted at the second end, and the second torsion arm is inserted at the end of the ear loop. In this case, the structure of the elastic element is simple, and the connection structure between the elastic element and the second end and the end of the ear loop is simple and easy to implement.

[0033] In some possible implementations, the ear hook end has an initial position and an adjusted position relative to the second end. In the initial position, the elastic element is compressed and has a first compression amount. The ear hook end can rotate relative to the second end to the adjusted position under the action of an external force. In the adjusted position, the elastic element is compressed and has a second compression amount, which is greater than the first compression amount.

[0034] In this implementation, the elastic element is in a pre-compressed state in the initial position, ensuring that the second end of the ear hook and the end of the ear hook maintain a relatively stable positional relationship when no external force is applied, which is beneficial for earphone storage. When adjusting the position, the elastic force of the elastic element increases, allowing for fine-tuning of the position of the end of the ear hook to fit the back of the user's ear and head, while maintaining a stable fit.

[0035] In some possible implementations, the ear hook end includes a connecting end and a suspension end, with the connecting end connecting to the second end. In the direction from the connecting end to the suspension end, the center points of each cross-section of the ear hook end are connected to form a centerline of the ear hook end, and this centerline is curved.

[0036] In this embodiment, the end of the ear hook is curved and has a non-centrally symmetrical structure. Therefore, the end of the ear hook can be rotated to adjust its posture, so as to better fit the back of the ear and head of different users and improve wearing comfort.

[0037] In some examples, the end of the ear loop can be a surface-symmetrical structure and a non-centrosymmetric structure. In this case, when the end of the ear loop rotates relative to the second end of the ear loop, its posture changes, and its relative position to the second end of the ear loop changes.

[0038] In some examples, the ear loop end may also exhibit a centrally symmetrical structure, but the center line of symmetry does not coincide with the central axis. In this case, when the ear loop end rotates relative to the second end of the ear loop, its relative position to the second end of the ear loop also changes.

[0039] In some possible implementations, the earcup may include a speaker and a circuit board, and the ear hook end includes a battery, with the ear hook electrically connected to the battery and the circuit board. In this implementation, the speaker and battery are located at the earcup and the ear hook end of the headphones, respectively, which can distribute the weight of the headphones and help improve the stability and comfort of wearing the headphones.

[0040] Secondly, embodiments of this application provide an earphone assembly, which includes a charging case and earphones as described above, wherein the charging case is used to store the earphones. Attached Figure Description

[0070] The embodiments of this application are described below with reference to the accompanying drawings.

[0071] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The term "multiple" refers to at least two. The term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. The term "integral-molded structural component" means that during the formation of one part of the structural component, that part is connected to another part without requiring further processing (such as bonding, welding, snap-fit ​​connection, screw connection) to connect the two parts together.

[0072] The directional terms mentioned in the embodiments of this application, such as "left", "right", "inner", "outer", "side", "upper", "lower", etc., are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0073] In the embodiments of this application, the relative positional relationships mentioned, such as parallel, perpendicular, and aligned, are defined in relation to the current technological level, rather than being absolutely strict. Slight deviations are permissible; approximations of parallelism, perpendicularity, or alignment are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0074] In the embodiments of this application, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature.

[0075] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an earphone 100 provided in an embodiment of this application.

[0076] In some embodiments, the earphone 100 may include an earcup 10, an ear hook 20, and an ear hook end 30. The ear hook 20 includes a first end 201 and a second end 202 opposite to each other, with the earcup 10 connected to the first end 201 and the ear hook end 30 connected to the second end 202. In this embodiment, the earphone 100 may be an ear hook type earphone, which can be suspended on the user's ear for wearing. The earphone 100 may also be a wireless earphone, capable of wirelessly connecting with other communication devices.

[0077] Other communication devices may include, but are not limited to, mobile phones, tablet personal computers, laptop computers, smart screens, personal digital assistants (PDAs), cameras, personal computers, laptops, in-vehicle devices, wearable devices, augmented reality (AR) glasses, AR helmets, virtual reality (VR) glasses, or VR helmets.

[0078] In some embodiments, the ear hook 20 is curved to allow the user to hang the earphone 100 on their ear for wearing.

[0079] For example, the earcup 10 may include a speaker 40 and a circuit board 50, and the ear hook end 30 may include a battery 60. The ear hook 20 is electrically connected to the battery 60 and the circuit board 50. In this embodiment, the speaker 40 and the battery 60 are located in the earcup 10 and the ear hook end 30 of the earphone 100, respectively, which can distribute the weight of the earphone 100 and help improve the stability and comfort of the earphone 100 when worn.

[0080] Please refer to the following: Figure 1 and Figure 2 , Figure 2 yes Figure 1 The diagram shows a partial exploded view of the structure of the earphone 100 in some embodiments.

[0081] In some embodiments, the second end 202 of the ear hook 20 may have a central axis 203, and the second end 202 of the ear hook 20 extends along the central axis 203. The ear hook end 30 is rotatably connected to the second end 202 of the ear hook 20 about the central axis 203, and the ear hook end 30 has a non-centrally symmetrical structure relative to the central axis 203.

[0082] In this application, since the ear hook end 30 is rotatably connected to the second end 202 of the ear hook 20 around the central axis 203, the ear hook end 30 has a non-centrally symmetrical structure relative to the central axis 203. Therefore, when the ear hook end 30 rotates relative to the second end 202 of the ear hook 20, the posture of the ear hook end 30 changes, and the relative position of the ear hook end 30 and the second end 202 of the ear hook 20 changes. For example, the tilt angle or tilt direction of the ear hook end 30 relative to the second end 202 of the ear hook 20 may change, or the relative position of a certain surface or area of ​​the ear hook end 30 with the second end 202 of the ear hook 20 may change. Therefore, when a user wears the headphones 100, the posture of the ear hook end 30 can be adjusted by rotating it, so that the ear hook end 30 rotates to a suitable position to fit well with the user's head and the back of the ear, improving the wearing fit of the ear hook end 30 and providing a better user experience.

[0083] When using the earphone 100, the user can directly twist the ear hook end 30, or press the ear hook 20 near the ear hook end 30 and then twist the ear hook end 30 to make the ear hook end 30 rotate relative to the second end 202 of the ear hook 20 to achieve posture adjustment.

[0084] For example, the second end 202 of the ear hook 20 can be inserted into the ear hook end 30. The ear hook end 30 rotates around the second end 202 of the ear hook 20 as a solid axis, which is simple and easy to implement. In some other embodiments, the earphone 100 can also be inserted into the second end 202 of the ear hook 20 through a partial structure of the ear hook end 30 to achieve a rotatable connection between the two. Alternatively, the earphone 100 can also connect the ear hook end 30 and the second end 202 of the ear hook 20 through an intermediate structural member to achieve a rotatable connection between the two.

[0085] It is understood that, in the embodiments of this application, the extension of the second end 202 of the ear hook 20 along the central axis 203 means that the overall structure of the second end 202 of the ear hook 20 extends approximately along the central axis 203. The centerline of the overall structure of the second end 202 of the ear hook 20 may completely coincide with, partially coincide with, be parallel to, or form a small angle with the central axis 203. Furthermore, the embodiments of this application do not limit every structure of the second end 202 of the ear hook 20 to extend along the central axis 203.

[0086] In some embodiments, the ear loop end 30 may include a connecting end 301 and a suspension end 302, with the connecting end 301 connected to the second end 202 of the ear loop 20. In the direction from the connecting end 301 to the suspension end 302, the center points of each cross-section of the ear loop end 30 are connected to form a center line 303 of the ear loop end 30, and the center line 303 is a curve.

[0087] In this embodiment, the ear hook end 30 is curved as a whole and has a non-centrally symmetrical structure. Therefore, the ear hook end 30 can be rotated to adjust its posture so as to better fit the back of the ear and head of different users and improve wearing comfort.

[0088] In some examples, the ear hook end 30 can be a surface-symmetrical structure and a non-centrally symmetrical structure. In this case, when the ear hook end 30 rotates relative to the second end 202 of the ear hook 20, its posture changes, and its relative position to the second end 202 of the ear hook 20 changes.

[0089] In some examples, the ear loop end 30 may also have a centrally symmetrical structure, but the center line of symmetry does not coincide with the central axis 203 of the second end 202 of the ear loop 20. In this case, when the ear loop end 30 rotates relative to the second end 202 of the ear loop 20, its relative position to the second end 202 of the ear loop 20 also changes.

[0090] In some examples, the ear hook end 30 has an asymmetrical structure. When the ear hook end 30 rotates relative to the second end 202 of the ear hook 20, its posture changes, and its relative position to the second end 202 of the ear hook 20 changes. It is understood that the shape of the ear hook end 30 can be implemented in various ways, and the embodiments of this application do not strictly limit it.

[0091] Please refer to the following: Figures 1 to 3 , Figure 3 yes Figure 2 The exploded structure diagram of the ear hook 20 is shown.

[0092] In some embodiments, the ear hook 20 may include a connector 1, a cover 2, a wire 3, a reinforcing wire 4, and a sealing ring 5.

[0093] The connector 1 is a rigid structural component. For example, the connector 1 can be made of materials such as plastic. The connector 1 is at least partially located at the second end 202 of the ear hook 20. For example, the main part or all of the connector 1 can be located at the second end 202 of the ear hook 20.

[0094] The wire 3 extends from the first end 201 of the ear hook 20 to the second end 202 of the ear hook 20. One end of the wire 3 can be connected to the ear cup 10, and the other end of the wire 3 can pass through the connector 1 and extend into the ear hook end 30. The wire 3 can achieve a conductive connection, used to conductively connect the device inside the ear cup 10 and the device inside the ear hook end 30. The portion of the wire 3 that passes through the connector 1 can be fixedly connected to the connector 1.

[0095] The end of the wire 3 that extends into the ear cup 10 and / or the ear hook end 30 may protrude relative to other structures of the ear hook 20 to facilitate connection with devices within the ear cup 10 / ear hook end 30. In this embodiment, the description of the extension direction of the second end 202 of the ear hook 20 may disregard the portion of the wire 3 protruding relative to other structures of the second end 202 of the ear hook 20.

[0096] The cover 2 covers the connector 1 and the wire 3, and the cover 2 is a flexible structural component. The cover 2 may be, but is not limited to, made of soft rubber material. In some examples, the cover 2 may extend from the first end 201 of the ear hook 20 to the second end 202 of the ear hook 20. In other examples, the cover 2 may also be located at a portion of the ear hook 20, such as at or near the second end 202 of the ear hook 20.

[0097] In this embodiment, the second end 202 of the ear hook 20 is fixed with the wire 3 by the rigid connector 1, which can ensure that the wire 3 is stably connected to the end 30 of the ear hook; the flexible covering 2 covers the connector 1 and the wire 3, which can play a role in buffering and protection, making the structure of the second end 202 of the ear hook 20 highly reliable.

[0098] For example, the stiffness of the reinforcing wire 4 is greater than that of the conductor 3 and also greater than that of the covering 2. The reinforcing wire 4 can be embedded inside the covering 2. In this case, the reinforcing wire 4 increases the structural stiffness of the ear hook 20, allowing the earphone 100 to be stably suspended by the ear hook 20, resulting in better wearing stability. The reinforcing wire 4 can extend along the extension direction of the ear hook 20 and be laid along its entire length to reinforce the ear hook 20 as a whole; alternatively, the reinforcing wire 4 can be laid along a portion of the length of the ear hook 20 to reinforce a specific area of ​​the ear hook 20. The reinforcing wire 4 can be, but is not limited to, at least one metal wire, such as steel wire.

[0099] For example, the sealing ring 5 is located at the second end 202 of the ear loop 20, and the sealing ring 5 surrounds the cover 2 and is fixed to the peripheral side of the cover 2.

[0100] In this embodiment, the sealing ring 5 and the covering component 2 can be integrally formed structural components. In this case, the connection structure between the sealing ring 5 and the covering component 2 is stable and reliable, and the processing technology is relatively simple. In some other embodiments, the sealing ring 5 can also be fixed to the covering component 2 by assembly.

[0101] For example, the number of sealing rings 5 ​​is at least two, and the at least two sealing rings 5 ​​are arranged at intervals along the central axis 203.

[0102] Please see Figure 4 , Figure 4 yes Figure 3 The diagram shows the structure of the cover 2 and the sealing ring 5 from another angle.

[0103] In some embodiments, the covering member 2 has a first groove 21, a second groove 22, a first hole 23, and a second hole 24. The first groove 21 is located at one end of the covering member 2, forming an opening on the end face of that end. A sealing ring 5 is disposed around the first groove 21. The second groove 22 is located on the bottom wall of the first groove 21. The first hole 23 and the second hole 24 are spaced apart and both communicate with the second groove 22. The first hole 23 and the second hole 24 can extend along the length of the covering member 2.

[0104] Please refer to the following: Figure 3 , Figure 5A and Figure 5B , Figure 5A yes Figure 3 Schematic diagram of the internal structure of connector 1 shown Figure 1 , Figure 5B yes Figure 3 Schematic diagram of the internal structure of connector 1 shown Figure 2 .

[0105] In some embodiments, the connector 1 includes a first body 11, a second body 12, a boss 13, and a limiting block 14. The first body 11 is cylindrical. The boss 13 is fixed to one end face of the first body 11, and the second body 12 is fixed to the other end face of the first body 11. The second body 12 is also cylindrical, with an outer diameter smaller than the outer diameter of the first body 11, and its centerline may coincide with the centerline of the first body 11. The limiting block 14 is fixed to the peripheral surface of the second body 12, and is spaced apart from the first body 11. There may be one or more limiting blocks 14; when there are multiple limiting blocks 14, they can be arranged at intervals along the circumference of the first body 11. The accompanying drawings illustrate an example with two limiting blocks 14.

[0106] The connector 1 may have a third hole 15 and a fourth hole 16. The third hole 15 passes through the boss 13, the first body 11, and the second body 12. The fourth hole 16 passes through the boss 13 and extends to the first body 11; or, the fourth hole 16 may also pass through the boss 13 and the first body 11 and extend to the second body 12. The end of the fourth hole 16 may be bent.

[0107] Please refer to the following: Figures 3 to 6 , Figure 6 yes Figure 2 The diagram shows the internal structure of the ear hook 20.

[0108] In some embodiments, the connector 1 is fixed to the inner side of the cover 2. Specifically, the boss 13 of the connector 1 is embedded in the second groove 22 of the cover 2, the first body 11 of the connector 1 is embedded in the first groove 21 of the cover 2, and the second body 12 and the limiting block 14 of the connector 1 are located on the outer side of the cover 2. The first body 11, the second body 12, and the limiting block 14 of the connector 1 are located at the second end 202 of the ear loop 20, and the portion of the cover 2 that covers the periphery of the first body 11 is located at the second end 202 of the ear loop 20.

[0109] The wire 3 is located inside the cover 2 and is inserted into the first hole 23 of the cover 2 and the third hole 15 of the connector 1, and is fixedly connected to the cover 2 and the connector 1. The third hole 15 can be tilted relative to the central axis 203 so that when the wire 3 extends out of the second end 202 of the ear loop 20, it can extend from the middle position of the second end 202.

[0110] The reinforcing wire 4 is located inside the covering 2. It is inserted into the second hole 24 of the covering 2 and the fourth hole 16 of the connector 1, and is fixedly connected to both the covering 2 and the connector 1. One end of the reinforcing wire 4 is connected to the connector 1. Because the end of the fourth hole 16 is bent, the end of the reinforcing wire 4 is also bent, making it less likely for the reinforcing wire 4 to detach from the connector 1, thus increasing the stability of the connection between the reinforcing wire 4 and the connector 1.

[0111] Please refer to the following: Figure 2 and Figure 7 , Figure 7 yes Figure 2 The diagram shows the exploded structure of the ear loop end 30.

[0112] In some embodiments, the ear loop end 30 may include a housing 6 and a mating component 7, the mating component 7 being fixed to the inner side of the housing 6. The housing 6 is the main structural component of the ear loop end 30, used to form the main shape and space of the ear loop end 30. The centerline of the ear loop end 30 is referenced to the outer surface of the housing 6. The housing 6 may include one or more shell components. For example, the housing 6 may include two assembled shell components, which can be assembled horizontally, vertically, at an angle, or using other combined assembly structures, as long as the design meets the requirements for processing and assembly. This application does not strictly limit this aspect.

[0113] Please refer to the following: Figures 8 to 9B , Figure 8 yes Figure 7 The diagram shows the structure of the shell 6 from another angle. Figure 9A yes Figure 7 Schematic diagram of the internal structure of the housing 6 shown Figure 1 , Figure 9B yes Figure 7 Schematic diagram of the internal structure of the housing 6 shown Figure 2 .

[0114] In some embodiments, the housing 6 may include a sleeve 61, a first protrusion 62, and a second protrusion 63. A through hole 610 is formed on the inner side of the sleeve 61, and the through hole 610 may be a cylindrical hole. At least a portion of the inner wall surface of the sleeve 61 is a cylindrical surface. Both the first protrusion 62 and the second protrusion 63 protrude from the inner wall surface of the sleeve 61. The first protrusion 62 and the second protrusion 63 may be arranged axially along the through hole.

[0115] The number of first protrusions 62 can be one or more. When there are multiple first protrusions 62, they are arranged at intervals along the circumference of the through hole 610. The accompanying drawings of this application illustrate an example with two first protrusions 62.

[0116] The number of second protrusions 63 can be the same as the number of first protrusions 62, and they are set to correspond one-to-one with the first protrusions 62.

[0117] For example, the housing 6 may also include a locking protrusion 64, which can be fixed to the bottom of the sleeve 61.

[0118] Please refer to the following: Figure 7 and Figure 10 , Figure 10 yes Figure 7 The structural schematic diagram of the mating part 7 shown from another angle.

[0119] In some embodiments, the mating component 7 may include a plate 71 and a protrusion 72, with the protrusion 72 protruding from the plate 71. The plate 71 may be generally circular. The plate 71 may have a locking groove 73, which is offset from the protrusion 72. There may be one or more protrusions 72; when there are multiple protrusions 72, they are arranged at intervals along the circumference of the plate 71. The accompanying drawings of this application illustrate an example with two protrusions 72.

[0120] The mating component 7 may further include an extension sleeve 74, which protrudes from the side of the plate 71 opposite to the protrusion 72. The plate 71 may have a hole that communicates with the inner space of the extension sleeve 74.

[0121] Please refer to the following: Figures 11A to 12 , Figure 11A yes Figure 2 Schematic diagram of the internal structure of the ear loop end 30 shown Figure 1 , Figure 11B yes Figure 2 Schematic diagram of the internal structure of the ear loop end 30 shown Figure 2 , Figure 12 yes Figure 2 Schematic diagram of the internal structure of the ear loop end 30 shown Figure 3 .

[0122] In some embodiments, the mating member 7 is fixed to the inside of the housing 6. For example, the peripheral edge of the plate 71 of the mating member 7 is fixedly connected to the sleeve 61, for example, it can be fixed to the bottom of the sleeve 61.

[0123] For example, the ear hook end 30 has an inner cavity 81 and a mounting hole 82. The mounting hole 82 connects the inner cavity 81 with the external space of the ear hook end 30. The mounting hole 82 and the inner cavity 81 can be located on opposite sides of the mating member 7. The sleeve 61 of the housing 6 can be arranged around the mounting hole 82, and the second protrusion 63 is located on the side of the first protrusion 62 facing the inner cavity 81.

[0124] The protrusion 72 of the mating part 7 can be located inside the sleeve 61. The protrusion 72 can be located between the first protrusion 62 and the plate 71. One end of the protrusion 72 can abut against the second protrusion 63, and the other end of the protrusion 72 can be spaced apart from another second protrusion 63.

[0125] For example, the wall of the mounting hole 82 may include a first surface 83 and a second surface 84, which are opposite to each other and spaced apart along the axial direction of the mounting hole 82. The first surface 83 may be located on the housing 6, for example, the first surface 83 may be located on the side surface of the first protrusion 62 facing the inner cavity 81; the second surface 84 may be located on the mating member 7, for example, the second surface 84 may be located on the plate 71.

[0126] For example, the wall of the mounting hole 82 may further include a third surface 85 and a fourth surface 86, which are arranged opposite to each other and spaced apart along the circumference of the mounting hole 82. The third surface 85 may be located on the housing 6, for example, on the surface of the second protrusion 63 near the first surface 83; the fourth surface 86 may be located on the mating member 7, for example, one end of the protrusion 72 of the mating member 7 abuts against the surface of the second protrusion 63 away from the third surface 85, and the other end of the protrusion 72 forms the fourth surface 86.

[0127] For example, a movable slot 87 is formed between the third surface 85 and the fourth surface 86. The movable slot 87 can also be located between the first surface 83 and the second surface 84. There can be one or more movable slots 87; when there are multiple movable slots 87, they are arranged at intervals along the circumference of the mounting hole 82. The accompanying drawings of this application illustrate a scenario with two movable slots 87.

[0128] For example, the locking protrusion 64 of the housing 6 (such as...) Figure 9A (As shown) can be snapped into the slot 73 of the plate 71 (e.g.) Figure 7 (As shown) to improve the assembly accuracy and connection stability between the fitting component and the housing 6.

[0129] Please refer to the following: Figure 13 and Figure 14 And see also Figure 11A and Figure 12 , Figure 13 yes Figure 1 The internal structure of the earphone 100 shown in some embodiments is illustrated. Figure 1 , Figure 14 yes Figure 1 The internal structure of the earphone 100 shown in some embodiments is illustrated. Figure 2 .

[0130] In some embodiments, the second end 202 of the ear hook 20 is inserted into the mounting hole 82 of the ear hook end 30. In this embodiment, since the second end 202 of the ear hook 20 is inserted into the mounting hole 82 of the ear hook end 30, the ear hook end 30 wraps around and protects the second end 202 of the ear hook 20, which helps to reduce the risk of damage to the second end 202 of the ear hook 20 and improves the structural reliability of the earphone 100.

[0131] In this design, the cover 2 of the ear hook 20 separates the connector 1 from the wall of the mounting hole 82. At this time, the second end 202 of the ear hook 20 is in flexible contact with the wall of the mounting hole 82, which helps to reduce the risk of the second end 202 of the ear hook 20 breaking during long-term use and improves the reliability of the headphone 100.

[0132] For example, the sealing ring 5 of the ear hook 20 is interference-fitted with the wall of the mounting hole 82. In this embodiment, the sealing ring 5 enables a sealed connection between the second end 202 of the ear hook 20 and the ear hook end 30, providing waterproofing and dustproofing to improve the reliability of the earphone 100. Furthermore, the sealing ring 5 also provides damping during the relative rotation of the second end 202 of the ear hook 20 and the ear hook end 30, resulting in a better user experience when rotating the ear hook end 30.

[0133] Damping can be controlled by adjusting the interference between the sealing ring 5 and the wall of the mounting hole 82, for example, by adjusting the protrusion height of the sealing ring 5, thereby controlling the force required for the user to rotate the end of the ear loop 30.

[0134] Furthermore, since at least two sealing rings 5 ​​are arranged at intervals along the central axis 203, the sealing performance between the second end 202 of the ear hook 20 and the end 30 of the ear hook is better, and the damping adjustment is more flexible.

[0135] For example, the limiting block 14 of the second end 202 of the ear hook 20 is engaged between the first surface 83 and the second surface 84.

[0136] In this embodiment, the first surface 83 of the ear hook end 30 can limit the second end 202 of the ear hook 20 by limiting the limiting block 14, preventing the second end 202 of the ear hook 20 from detaching from the ear hook end 30; the second surface 84 of the ear hook end 30 can limit the second end 202 of the ear hook 20 by limiting the limiting block 14, preventing the second end 202 of the ear hook 20 from excessively extending into the ear hook end 30. Therefore, the ear hook end 30 improves the assembly accuracy and connection reliability of the second end 202 of the ear hook 20 and the ear hook end 30 by the joint limiting of the limiting block 14 by the first surface 83 and the second surface 84.

[0137] In addition, the ear hook end 30 has the first surface 83 and the second surface 84 respectively set on the housing 6 and the mating part 7, and then the limiting block 14 is limited by the assembly structure of the housing 6 and the mating part 7. This not only reduces the structural processing difficulty of the ear hook end 30, but also helps to reduce the assembly difficulty of the earphone 100.

[0138] For example, the limiting block 14 is also located between the third surface 85 and the fourth surface 86. When the ear loop end 30 rotates relative to the second end 202 of the ear loop 20, the limiting block 14 moves between the third surface 85 and the fourth surface 86.

[0139] In this embodiment, the ear hook end 30 limits the movement of the limiting block 14 in the circumferential direction through the third surface 85 and the fourth surface 86, thereby limiting the relative rotation angle between the second end 202 of the ear hook 20 and the ear hook end 30, so as to avoid the relative rotation angle between the two being too large and damaging the internal connecting parts (such as the wire 3) of the ear hook 20 and the ear hook end 30, thus improving the reliability of the earphone 100.

[0140] For example, by adjusting the spacing between the third surface 85 and the fourth surface 86 in the circumferential direction of the mounting hole 82, and / or adjusting the width of the limiting block 14 in the circumferential direction of the mounting hole 82, the range of rotation angles of the ear hook end 30 relative to the second end 202 of the ear hook 20 can be adjusted.

[0141] For example, multiple limit blocks 14 are located one-to-one within multiple active slots 87.

[0142] In this embodiment, the ear hook end 30 and the second end 202 of the ear hook 20 are connected by multiple movable slots 87 and multiple limiting blocks 14, thereby limiting the two in multiple places around the central axis 203, making the limiting structure of the two more stable and reliable.

[0143] In this embodiment of the application, by setting the self-structure and mating structure of the housing 6 and the mating parts 7, such as the position and structural design of the first surface 83 to the fourth surface 86, the processing difficulty of the ear hook end 30 and the assembly difficulty with the second end 202 of the ear hook 20 are reduced, which is conducive to improving the manufacturing yield of the earphone 100.

[0144] For example, battery 60 (see reference) Figure 1 The ear hook 20 can be installed in the inner cavity 81. For example, one end of the wire 3 of the ear hook 20 extends into the inner cavity 81 of the ear hook end 30 to facilitate connection to a device located in the inner cavity 81, such as a battery 60. The wire 3 also passes through the extension sleeve 74 of the mating member 7, which can guide the position of the wire 3 and help protect the wire 3.

[0145] In the preceding embodiments, the first surface 83 and the third surface 85 of the ear loop end 30 are located on the housing 6, and the second surface 84 and the fourth surface 86 are located on the mating part 7. In some other embodiments, the first surface 83 of the ear loop end 30 may be located on the housing 6, and the second surface 84, the third surface 85, and the fourth surface 86 may be located on the mating part 7; or, the first surface 83, the third surface 85, and the fourth surface 86 may be located on the housing 6, and the second surface 84 may be located on the mating part 7.

[0146] In this embodiment, the ear hook end 30 has some structures from the first surface 83 to the fourth surface 86 disposed on the housing 6 and some structures disposed on the mating part 7. Then, the limiting block 14 is limited by the assembly structure of the housing 6 and the mating part 7. This not only reduces the structural processing difficulty of the ear hook end 30, but also helps to reduce the assembly difficulty of the earphone 100. In this embodiment, the specific constituent structure of the first surface 83 to the fourth surface 86 and the specific mating structure of the ear hook end 30 and the mating part 7 are not strictly limited.

[0147] It is understood that in some other embodiments, the ear hook end 30 may also adopt other structures to form spaces such as mounting hole 82, inner cavity 81, movable slot 87, etc., and to form limiting surfaces such as first surface 83, second surface 84, third surface 85 and fourth surface 86. The specific structure and configuration of the ear hook end 30 are not strictly limited in the embodiments of this application.

[0148] Please see Figure 15 , Figure 15 yes Figure 1 The diagram shows a partial exploded view of the structure of the earphone 100 in some other embodiments. The earphone 100 in this embodiment may include most of the technical features of the earphone 100 in the previous embodiments. The following mainly describes the differences between the two, and the majority of the contents that are the same in both will not be repeated.

[0149] In some embodiments, the earphone 100 may further include an elastic element 9 for connecting the second end 202 of the ear hook 20 to the ear hook end 30. For example, the elastic element 9 may be a torsion spring, which includes a helical spring body 91 and a first torsion arm 92 and a second torsion arm 93.

[0150] Among them, the structure of the second end 202 of the ear hook 20 and the structure of the end 30 of the ear hook 20 are adapted to the assembly requirements of the elastic element 9.

[0151] Please refer to the following: Figure 16 and Figure 17 , Figure 16 yes Figure 15 An exploded structural diagram of part of the ear loop 20 shown. Figure 17 yes Figure 16 A schematic diagram of the internal structure of the connector 1 of the ear hook 20 shown.

[0152] In some embodiments, the ear hook 20 may include a connector 1, a cover 2, a wire 3, a reinforcing wire 4, and a sealing ring 5.

[0153] The connector 1 may include a first body 11, a second body 12, a boss 13, a limiting block 14, and a positioning boss 17. The positioning boss 17 is fixed to the back of the second body 12 facing away from the first body 11, and a third hole 15 can penetrate the positioning boss 17. The outer peripheral surface of the positioning boss 17 can be a cylindrical surface. The connector 1 may also have an insertion hole 18, which may be partially located in the second body 12, partially located in the limiting block 14, or entirely located in either the second body 12 or the limiting block 14. Other embodiments of the connector 1 are described in the preceding embodiments and will not be repeated here.

[0154] Please see Figure 18 , Figure 18 yes Figure 15 The diagram shows the assembly structure of the ear hook 20 and the elastic element 9.

[0155] In some embodiments, the helical spring body 91 of the torsion spring (i.e., elastic element 9) can be sleeved on the positioning boss 17 of the connector 1, which can position the approximate location of the torsion spring. The first torsion arm 92 of the torsion spring can be inserted into the second end 202 of the ear loop 20. For example, the first torsion arm 92 of the torsion spring can be inserted into the insertion hole 18 of the connector 1.

[0156] Please refer to the following: Figures 19 to 21B , Figure 19 yes Figure 15 The diagram shows an exploded view of the ear loop end 30. Figure 20 yes Figure 19 The diagram shows the structure of the mating component 7 from another angle. Figure 21A yes Figure 15 Schematic diagram of the internal structure of the ear loop end 30 shown Figure 1 , Figure 21B yes Figure 15 Schematic diagram of the internal structure of the ear loop end 30 shown Figure 2 .

[0157] In some embodiments, the ear loop end 30 may include a housing 6 and a mating member 7, the mating member 7 being mounted inside the housing 6. The mating member 7 may include a plate 71 and a protrusion 72. A portion of the plate 71 may be recessed away from the protrusion 72 to form a recess 75. The plate 71 may also have a through hole 76 in the bottom wall of the recess 75.

[0158] The ear hook end 30 also includes spaces such as an inner cavity 81, a mounting hole 82, and a movable slot 87, as well as surfaces such as a first surface 83, a second surface 84, a third surface 85, and a fourth surface 86. The recessed groove 75 can form part of the mounting hole 82, and the through hole 76 can connect the mounting hole 82 and the inner cavity 81. Other designs for the ear hook end 30 are described in the preceding embodiments and will not be repeated here.

[0159] Please refer to the following: Figures 22 to 24 , Figure 22 yes Figure 1 The internal structure of the earphone 100 shown in some other embodiments is illustrated. Figure 1 , Figure 23 yes Figure 1 The internal structure of the earphone 100 shown in some other embodiments is illustrated. Figure 2 , Figure 24 yes Figure 1 The internal structure of the earphone 100 shown in some other embodiments is illustrated. Figure 3 .

[0160] In some embodiments, the second end 202 of the ear hook 20 is inserted into the mounting hole 82 of the ear hook end 30, and the second end 202 of the ear hook 20 and the ear hook end 30 are rotatably connected about the central axis 203. The limiting block 14 of the connector 1 is also limited between the first surface 83 and the second surface 84, and between the third surface 85 and the fourth surface 86.

[0161] For example, the torsion spring (i.e., the elastic element 9) is located in the mounting hole 82, for example, it can be located in the recess 75. The centerline 94 of the helical spring body 91 of the torsion spring can be parallel to the central axis 203. Wherein, when the centerline 94 of the helical spring body 91 and the central axis 203 form a small angle (e.g., less than 20°), they are also considered to be parallel. When the first torsion arm 92 of the torsion spring is inserted into the second end 202 of the ear loop 20, the other second torsion arm 93 of the torsion spring is inserted into the end 30 of the ear loop. For example, the second torsion arm 93 of the torsion spring can be inserted into the housing 6.

[0162] In this embodiment, the elastic element 9 connects the second end 202 of the ear hook 20 to the ear hook end 30. When the ear hook end 30 and the second end 202 of the ear hook 20 rotate relative to each other, the elastic element 9 deforms.

[0163] In this embodiment, when a user wears the earphone 100, the ear hook end 30 can be rotated at an angle. Then, under the elastic force of the elastic member 9, the ear hook end 30 can automatically fit the back of the user's ear and head, and maintain a stable fit after fitting, thereby improving the wearing convenience, fit and stability of the earphone 100.

[0164] In addition, the elastic element 9 is a torsion spring. The structure of the elastic element 9 is simple, and the connection structure between the elastic element 9 and the second end 202 of the ear hook 20 and the end 30 of the ear hook is simple and easy to implement.

[0165] For example, the ear hook end 30 can have an initial position and an adjusted position relative to the second end 202 of the ear hook 20. In the initial position, the elastic element 9 is compressed and has a first compression amount. The ear hook end 30 can rotate relative to the second end 202 of the ear hook 20 to the adjusted position under the action of an external force. For example, when the user twists the ear hook end 30, causing the ear hook end 30 to rotate at an angle relative to the second end 202 of the ear hook 20, the ear hook end 30 rotates from the initial position to the adjusted position. In the adjusted position, the elastic element 9 is compressed and has a second compression amount, which is greater than the first compression amount. At this time, the ear hook end 30 can rotate from the adjusted position and be finely adjusted to a position that fits the back of the user's ear and head under the elastic force of the elastic element 9, which can also be understood as a fitting position.

[0166] In this embodiment, in the initial position, the elastic element 9 is in a pre-compressed state, so that the second end 202 of the ear hook 20 and the end 30 of the ear hook maintain a relatively stable positional relationship when no external force is applied, which is beneficial for the storage of the earphone 100. When adjusting the position, the elastic force of the elastic element 9 increases, which allows the position of the end 30 of the ear hook to be finely adjusted to fit the back of the user's ear and head, and to maintain a stable fit.

[0167] It is understood that other solutions for the headphone 100 in this embodiment can be found in the relevant descriptions of the previous embodiments, and will not be repeated here.

[0168] This application embodiment also provides an earphone assembly, which includes a charging case and the aforementioned earphones 100. The charging case is used to store the earphones 100. The charging case can also be called a charging case or earphone case. The charging case contains a battery, which can charge the earphones 100 stored inside the case to meet the user's needs for long-term use. For example, the charging case may have two earphone slots, which can be used to hold the left and right earphones respectively.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
