Technical Field

[0001] The invention relates to the technical field of earphones, in particular to a wire-hiding structure, an earphone and an assembly method thereof. Background Art

[0002] Although many electronic products on the market use wireless connections to optimize wire issues, they also bring problems such as high latency, poor transmission stability, insufficient power, and non-plug-and-play. Therefore, for practical products, they tend to choose wired connections. For many active headphone products, most of their components must be movable to meet ergonomic design. The length of the wire will affect the appearance and function of the headphone product. The external wiring and internal connection of the product are problems that many electronic products need to face, including the service life of the wire. In existing expandable and deformable headphone products, the internal wires are easily constrained by length or pulled by the solder joints after the headphones are deformed, which affects the performance or service life of the wires.

[0003] Therefore, the earphones need to be improved to reduce the impact of expansion deformation on the wires and better improve the user experience of the earphones. Summary of the invention

[0004] In view of the technical problem that in the above-mentioned expandable and deformable earphone products, the internal wires are easily constrained in length or pulled by the welding points after the earphones are deformed, thereby affecting the performance or service life of the wires, the technical solution adopted by the present invention to solve the technical problem is: A wire hiding structure comprises a shell, wherein the shell is provided with a first channel for one end of a wire to pass through, a second channel for the other end of the wire to pass through, and a storage space located between the first channel and the second channel, wherein the storage space is provided with a limit end, and when the wire moves out of or passes into the first channel or the second channel, the limit end is used to keep the wire bent in the storage space, and the storage space is symmetrically arranged, and the wire is arranged in an S shape in the storage space.

[0005] Furthermore, in some embodiments of the present invention, the storage space is provided with an arc-shaped inner wall abutting against the wire, and the limiting ends are respectively arranged between the arc-shaped inner wall and the first channel, and between the arc-shaped inner wall and the second channel.

[0006] Further, in some embodiments of the present invention, the arcuate inner wall includes a first arcuate inner wall arranged opposite to the first channel, the limit end includes a first limit end arranged between the first arcuate inner wall and the second channel, the arcuate inner wall includes a second arcuate inner wall arranged opposite to the second channel, and the limit end includes a second limit end arranged between the second arcuate inner wall and the first channel.

[0007] Furthermore, in some embodiments of the present invention, the storage space is provided with a first straight inner wall located between the first channel and the first arc-shaped inner wall, and a second straight inner wall located between the second channel and the second arc-shaped inner wall.

[0008] Furthermore, in some embodiments of the present invention, the first limit end is arranged in a V-shape, the first limit end protrudes toward the second arc-shaped inner wall, and the first limit end is provided with a first arc-shaped limit end connected to the first arc-shaped inner wall and a first straight limit end connected to the second channel.

[0009] Furthermore, in some embodiments of the present invention, the second limit end is arranged in a V-shape, the two limit ends protrude toward the first arc-shaped inner wall, and the second limit end is provided with a second arc-shaped limit end connected to the second arc-shaped inner wall and a second straight limit end connected to the first channel.

[0010] Furthermore, in some embodiments of the present invention, the first channel, the storage space, and the second channel are enclosed in an S-shape, and the first channel and the second channel are staggered and arranged relative to each other.

[0011] Another object of the present invention is to provide an earphone, comprising the wire hiding structure as described above, wherein the shell is connected to a cover body, and the cover body is used to cover the storage space.

[0012] Furthermore, in some embodiments of the present invention, the cover body is provided with a cover body cavity, the cover body cavity structure is symmetrically arranged with the storage space structure, and the cover body is detachably connected to the shell.

[0013] Another object of the present invention is to provide an assembling method of an earphone, comprising the earphone as described above, wherein the assembling method comprises: S1, passing one side of the wire into the storage space from one side of the first channel or the second channel; S2, the wire is in contact with the limit end and bent into an S shape; S3, passing one side of the wire out of the storage space from the other side of the first channel or the second channel; S4.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 9 A wire hiding structure shown in the figure comprises a shell 1, wherein the shell 1 is provided with a first channel 3 for one end of a wire 2 to pass through, a second channel 4 for the other end of the wire 2 to pass through, and a storage space 5 located between the first channel 3 and the second channel 4, wherein the storage space 5 is provided with a limiting end 6, and when the wire 2 movably passes through the first channel 3 or the second channel 4, the limiting end 6 is used to keep the wire 2 bent and arranged in the storage space 5.

[0028] During the expansion and deformation process of traditional headphones, the built-in wires will be forcibly pulled due to the limited length, and the solder joints will also be subjected to huge stress, which is very likely to cause wire breakage, insulation layer damage or solder joint shedding, greatly shortening the life of the wires. The present invention provides a buffer space for the wires by cooperating with the storage space and the limit end. When different parts of the headphones are expanded or bent and deformed, the wires located in the storage space can adaptively move in the first channel or the second channel, thereby reducing the problem of solder joint pulling or wire breakage. When the deformation of the headphones causes the length of the wires to change, the wires can bend or shrink in the storage space, avoiding direct over-stretching. At the same time, the limit end constrains the bending shape of the wires to ensure that they will not be excessively displaced, greatly reducing the pulling on the solder joints, allowing the built-in activities of the wires to be free of length constraints, thereby maintaining the physical integrity of the wires and extending their service life. When the elastic parts of the headphones are restored, the wires are restricted by the limit end and change from a contracted state to a bent state again.

[0029] Furthermore, as a preferred embodiment of the present invention but not a limitation, in the prior art, in order to deal with the problems that may arise when the wire is expanded or bent, it is often necessary to reserve a larger redundant length of the wire, which undoubtedly occupies the internal space of the earphone and easily causes knots or squeezing between the wires to create fault points. The present invention can limit the movement path of the wire by setting a storage space. Under the premise of ensuring the safety of the wire and reducing pulling, the required wire length can be controlled to reduce unnecessary space occupation, so that the earphones can be more easily designed in the direction of miniaturization and lightweight while realizing the complex wire hiding function, thereby meeting the market demand for portable earphones.

[0030] like Figures 1 to 7 In the wire hiding structure shown, the first channel 3 and the second channel 4 are arranged relative to each other in a staggered manner, and the storage space 5 is arranged symmetrically.

[0031] Furthermore, as a preferred embodiment of the present invention but not a limitation, the first channel and the second channel are offset and relatively arranged to prevent the wire from being pulled and moved in a straight line on the one hand, and on the other hand, allow the wire to form a symmetrical layout inside the earphone. When the earphone undergoes expansion deformation, no matter from which direction the external force is applied, the pulling force on both ends of the wire can be more evenly distributed throughout the wire-hiding structure. For example, in a sports scene, the user's head shakes quickly, and the symmetrical channel design prevents the wire from being overstressed on one side and relatively loose on the other side, effectively avoiding wire damage caused by uneven force and greatly extending the service life of the wire.

[0032] Specifically, the symmetrical storage space provides a stable and symmetrical buffer area for the wires during the bending and storage process. Regardless of whether the wires enter or exit from the first channel or the second channel, they can receive equal protection in the corresponding symmetrical storage space, ensuring that the forces on various parts of the wires are coordinated and consistent, reducing stress concentration points.

[0033] In addition, the offset relative setting of the first channel and the second channel and the symmetrical design of the storage space can more efficiently utilize the limited space inside the headset and avoid wasting space or confusing layout. Compared with the asymmetric design, it can more reasonably plan the direction, storage position and spacing of the wires with the same space volume, and reserve regular and sufficient installation space for other key components such as batteries and circuit boards, so that the headset can achieve a compact and delicate structural design.

[0034] Furthermore, when installing wires, due to the symmetry of the channels and storage spaces, workers can easily follow a unified standard operating procedure to pass the wires through the corresponding channels and accurately place them in the symmetrical storage spaces, greatly shortening the assembly time.

[0035] like Figures 1 to 7 In the wire hiding structure shown, the first channel 3, the storage space 5, and the second channel 4 are surrounded in an S-shape, and the wire 2 is arranged in the storage space in an S-shape.

[0036] Furthermore, as a preferred embodiment of the present invention but not a limitation, the S-shaped layout can make full use of the originally irregular or difficult to use narrow and long space inside the earphone. Compared with the straight or simply curved channel and storage space design, it can fit the internal contour of the earphone, further arrange the wires in a limited space area, free up more regular layout space for other components, and realize the compact optimization of the internal structure of the earphone.

[0037] Specifically, the wires are arranged in an S shape in the storage space, ensuring the effective use of the wire length. The reserved wires will not be too long, causing messy storage and entanglement, nor will the wires be too short to adapt to the expansion or bending deformation of the headphones, so that the wires can be stored in an orderly manner and used efficiently in a limited space. When the headphones are subject to expansion and deformation, the S-shaped wire layout can disperse the stress in a progressive manner. Under the action of external force, the wire is not subjected to sudden huge tension at a certain point or section, but along the S-shaped curve, the tension is evenly dispersed to multiple bending parts and segments. The impact force and pulling force from different directions are gradually dissipated to avoid stress concentration, greatly reduce the risk of wire breakage, and extend its service life.

[0038] In addition, the S-shaped enclosure of the first channel, the storage space and the second channel provides a stable support structure for the wire. When the wire moves in the S-shaped channel, each bending point and line segment can be restrained and buffered by the inner wall of the enclosure structure, preventing the wire from deviating from the path due to excessive shaking and displacement, further ensuring the integrity of the wire in a complex force environment.

[0039] Furthermore, the S-shaped layout effectively controls the position and direction of the wires, reducing the noise and hum caused by wire interference, ensuring that the headphones can work stably and maintain good acoustic performance, bringing users a clearer and more realistic listening experience.

[0040] Optionally, in some embodiments, a storage space is provided between the neck ring 7 and the earpiece of the headset, and when the neck ring expands and deforms, the wires in the neck ring require more wire length to adapt to the expansion path of the neck ring, and the wires in the neck ring can drive the wires in the storage space to move toward the side close to the neck ring. At this time, the wires switch from a bent and stored state to a bent and contracted state. When the neck ring is reset, the expansion path of the neck ring is restored and shortened, and the wires in the neck ring need to shorten the wire length to adapt to the neck ring. The wires are synchronously reset under the drive of the limit end, so that the wires can be stored in the storage space and switch from the bent and contracted state to the bent and stored state.

[0041] Optionally, in some embodiments, the storage space is provided between the neck ring 7 and the microphone rod 8 of the earphone. Similarly, when the neck ring expands and deforms, the wire can be driven to move to the side close to the neck ring. When the neck ring is reset, the wire is reset synchronously under the drive of the limit end, so that the wire can be stored in the storage space. When the microphone rod is bent and deformed, the wire inside the microphone rod needs more wire length to adapt to the bending path of the microphone rod. The wire of the microphone rod can drive the wire in the storage space to move to the side close to the microphone rod. At this time, the wire switches from the bent storage state to the bent contraction state. When the microphone rod is reset, the bending path of the microphone rod is restored and shortened. The wire inside the microphone rod needs to shorten the wire length to adapt to the microphone rod. The wire is reset synchronously under the drive of the limit end, so that the wire can be stored in the storage space and switch from the bent contraction state to the bent storage state.

[0042] If the wire is arranged in the storage space in a wavy or continuous S shape, the wire with a width that is too small may easily become tangled and entangled if it cannot fit tightly in the storage space, and the partially coiled position may abut against the limit end in advance, resulting in the wire being unable to be further stretched and the wire length in the storage space being unable to be fully utilized, which may also easily cause damage to the wire surface.

[0043] like Figures 1 to 7 In the wire hiding structure shown, the storage space 5 is provided with an arc-shaped inner wall 51 abutting against the wire 2, and the limiting ends 6 are respectively arranged between the arc-shaped inner wall 51 and the first channel 3, and between the arc-shaped inner wall 51 and the second channel 4.

[0044] Furthermore, as a preferred embodiment of the present invention but not a limitation, the arc-shaped inner wall provided in the storage space abuts against the wire, which can provide an additional support surface for the wire. When the earphone is deformed, the wire fits tightly against the arc-shaped inner wall during the bending process, dispersing the pressure on the wire and avoiding stress concentration at a certain point that causes damage to the wire. The arc-shaped design can better conform to the bending curvature of the wire, reduce the friction between the wire and the inner wall of the storage space by sliding, reduce the risk of wear of the insulation layer, and further ensure the physical properties of the wire.

[0045] Specifically, the limiting ends are respectively arranged between the arc-shaped inner wall and the first channel, and between the arc-shaped inner wall and the second channel, so as to limit the bending area when the wire passes through the first channel or the second channel. By working together with the arc-shaped inner wall, the movement of the wire is restricted to a certain extent in the buffer zone of the storage space, thereby minimizing unnecessary displacement of the wire during the deformation process. On the one hand, it avoids the wire from being unable to return to its original position after leaving the storage space, and on the other hand, it can reduce the pulling on the welding point and extend the service life of the wire.

[0046] In addition, compared with traditional right-angle or flat inner walls, the curved inner wall design can provide a larger contact area and more reasonable bending space for the wires within the same spatial volume, allowing the storage space to be more fully utilized. Without increasing the overall size of the earphones, it can accommodate more wires of varying lengths, optimize the layout of the wire storage structure, and contribute to the compact design of the internal structure of the earphones.

[0047] like Figures 3 to 7 In the wire-hiding structure shown, the arc-shaped inner wall 51 includes a first arc-shaped inner wall 511 arranged opposite to the first channel 3 , and the limiting end 6 includes a first limiting end 61 arranged between the first arc-shaped inner wall 511 and the second channel 4 .

[0048] Furthermore, as a preferred embodiment of the present invention but not a limitation, since the first curved inner wall is arranged opposite to the first channel, when the wire passes through the first channel, it can naturally bend along the curvature of the first curved inner wall, providing a guide for the wire to enter the storage space, avoiding the wire from bending dead corners or scratching with other components due to loss of direction control at the entrance, greatly reducing the risk of damage to the wire.

[0049] Specifically, the first limit end disposed between the first arc-shaped inner wall and the second channel can control the path of the wire from the storage space to the second channel. It ensures that the wire passes out at a predetermined, optimized bending angle and position when leaving the storage space, preventing the wire from being overstretched or twisted, effectively protecting the integrity of the wire and ensuring the stable operation of the earphone.

[0050] In addition, the first curved inner wall makes full use of the space between the first channel and the second channel, and by fitting the natural bending characteristics of the wire, the wire is smoothly stored with minimal space occupancy, so that the limited space inside the earphone is used more efficiently, and more layout space is reserved for other components, which contributes to the miniaturization and lightweight design of the overall structure of the earphone.

[0051] Furthermore, due to the control of the wire path by the first limiting end, even if the earphones experience repeated expansion and deformation during frequent use, such as severe shaking of the earphones during running or jumping by sports enthusiasts, the wire can always move stably within the range defined by the first arc-shaped inner wall and the first limiting end, ensuring the continuity and stability of signal transmission, effectively reducing problems such as audio signal interruption or distortion caused by loose wires and displacement, greatly enhancing the reliability of the earphones, thereby improving the user experience.

[0052] like Figures 3 to 7 In the illustrated wire-hiding structure, the arc-shaped inner wall 51 includes a second arc-shaped inner wall 512 arranged opposite to the second channel 4 , and the limiting end 6 includes a second limiting end 62 arranged between the second arc-shaped inner wall 512 and the first channel 3 .

[0053] Furthermore, as a preferred embodiment of the present invention but not a limitation, the second arc-shaped inner wall is arranged opposite to the second channel, providing a bending support for the wire passing through the second channel. When the wire passes through the storage space from the second channel, the wire can smoothly enter the storage space along the second arc-shaped inner wall, avoiding wire wear or excessive bending caused by a poor entrance angle. By cooperating with the first arc-shaped inner wall, all-round guidance of the wire entering the storage space from different directions is achieved, greatly reducing the probability of wire damage.

[0054] Specifically, the second limit end located between the second arc-shaped inner wall and the first channel controls the path of the wire from the storage space back to the first channel. It complements the first limit end, and has a corresponding limit effect regardless of whether the wire moves forward or backward, ensuring that the wire follows the preset angle and position when passing through, preventing stretching and twisting caused by improper passing, protecting the integrity of the wire in all directions, and ensuring the stable operation of the headset.

[0055] In addition, the setting of the second curved inner wall can adapt to the direction of the wire, making the storage space layout more balanced and symmetrical without increasing the overall volume, further improving the space utilization efficiency and achieving a compact and reasonable structural design.

[0056] like Figure 3In the wire-hiding structure shown, the storage space 5 is provided with a first straight inner wall 521 located between the first channel 3 and the first arc-shaped inner wall 511 , and a second straight inner wall 522 located between the second channel 4 and the second arc-shaped inner wall 512 .

[0057] Furthermore, as a preferred embodiment of the present invention but not a limitation, the first straight inner wall is located between the first channel and the first curved inner wall. When the wire passes through the first channel, it provides a straight guide for the wire, thereby ensuring that the wire can move smoothly along the first straight inner wall before entering the first curved inner wall, avoiding the wire from becoming scattered, entangled or excessively bent immediately after passing through the channel, thereby reducing the risk of damage to the starting section of the wire.

[0058] Furthermore, the second straight inner wall is located between the second channel and the second curved inner wall, and plays a guiding role for the wire passing through the second channel, so that the wire can transition to the second curved inner wall in an orderly manner, thereby ensuring the smoothness of the wire passing process.

[0059] Specifically, the first straight inner wall cooperates with the first curved inner wall, so that when the wire enters the storage space, the first straight inner wall assists the wire to move forward stably, and the first curved inner wall provides buffering and protection for the wire, making the wire storage process more streamlined and improving the space utilization. Furthermore, the second straight inner wall cooperates with the second curved inner wall to achieve symmetrical space partitioning for the wires that penetrate, so that no matter whether the wires move forward or backward, they can be balanced on both sides of the storage space, avoiding various problems caused by the wires running around in the storage space.

[0060] Specifically, when the earphones frequently undergo expansion and deformation, the first straight inner wall and the second straight inner wall provide additional support points for the wire. For example, when the earphones are squeezed laterally, causing the wire to have a tendency to move in the storage space, the first straight inner wall and the second straight inner wall can support the wire and prevent it from excessive displacement, and together with the first curved inner wall, the second curved inner wall, and the limit end, they build a stable three-dimensional support system to ensure that the wire remains firmly in the storage space under complex force conditions, thereby ensuring the stability of the earphone audio transmission.

[0061] like Figure 3 A hidden wire structure is shown, wherein the first limiting end 61 is arranged in a V-shape, the first limiting end 61 protrudes toward the second arc-shaped inner wall 512, and the first limiting end 61 is provided with a first arc-shaped limiting end 611 close to the first arc-shaped inner wall 511 and a first straight limiting end 612 close to the second channel 4.

[0062] Furthermore, as a preferred embodiment of the present invention but not a limitation, the shape of the first limit end arranged in a V-shape provides multi-dimensional constraints for the wire. The design of convex toward the second arc-shaped inner wall can effectively limit the lateral displacement and longitudinal deviation of the wire in the process of passing from the storage space to the second channel. The first arc-shaped limit end is close to the first arc-shaped inner wall, and can accurately clamp the wire to prevent it from deviating from the path due to excessive movement in the bending area, ensuring that the wire moves along a predetermined trajectory that fits the arc-shaped inner wall, thereby ensuring the stability of the wire in the bending part.

[0063] Specifically, the first straight limit end is close to the second channel, and plays a calibration role for the wire passing through the second channel. It ensures that the wire enters the second channel in a straight and stable state, avoids the wire from being skewed, entangled, and other chaos in the second channel, and avoids various faults caused by poor wire passing.

[0064] Furthermore, as a preferred embodiment of the present invention but not a limitation, when the first limit end of the V-shaped structure contacts the wire, it can disperse the tension on the wire. When the earphone expands and deforms, and the wire is subjected to an outward pulling force, the first arc-shaped limit end and the first straight limit end each bear a portion of the force. Compared with the traditional single limit structure, the stress concentration on the wire is greatly reduced, the risk of wire breakage due to uneven force is reduced, and the service life of the wire is extended.

[0065] Specifically, the first limit end utilizes the irregular space between the first arc-shaped inner wall and the second channel. The V-shaped design can flexibly adjust the limit angle according to the width of the space in the area, which can fully exert the limit function without taking up too much unnecessary space, making the layout around the storage space more compact and reasonable, which helps to optimize the overall structure of the headset and integrate more functions in a limited space.

[0066] Optionally, in order to improve the continuity of the storage space, the first arc-shaped limiting end 611 is connected to the first arc-shaped inner wall 511 , and the first straight limiting end 612 is connected to the second channel 4 .

[0067] like Figure 3 A hidden wire structure is shown, wherein the second limiting end 62 is arranged in a V-shape, and the second limiting end 62 protrudes toward the first arc-shaped inner wall 511. The second limiting end 62 is provided with a second arc-shaped limiting end 621 close to the second arc-shaped inner wall 512 and a second straight limiting end 622 close to the first channel 3.

[0068] Furthermore, as a preferred embodiment of the present invention but not a limitation, the second limit end is arranged in a V-shape and convex to the first arc-shaped inner wall, forming a symmetrical layout with the first limit end. The wire is multi-dimensionally constrained from opposite directions. When the wire passes from the storage space to the first channel, the second limit end can limit the lateral displacement of the wire or the longitudinal deviation in the direction close to the first arc-shaped inner wall. The second arc-shaped limit end is close to the second arc-shaped inner wall, closely fitting the bending path of the wire, ensuring the stable transition of the wire in the reverse bending area, preventing it from deviating from the track, and ensuring the stability of the wire in the key bending part.

[0069] Specifically, the second straight limit end is close to the first channel, ensuring that the wire can pass through smoothly in a regular and straight state, avoiding problems such as entanglement and skewness at the exit, and preventing various faults caused by abnormal wire passing through. It cooperates with the first straight limit end to realize the control of the two-way passing of the wire.

[0070] In addition, when the second limit end of the V-shaped structure contacts the wire, it cooperates with the first limit end to form an efficient dispersed pulling force. When the earphones face expansion deformation in different directions, causing the wire to be pulled, the second arc limit end and the second straight limit end of the V-shaped structure each bear part of the force, avoiding excessive stress on the wire locally, and working together with the first limit end, all-roundly reducing the stress concentration phenomenon of the wire, greatly reducing the risk of wire breakage, further extending its service life, and ensuring the continuity of audio transmission of the earphones under various working conditions.

[0071] Furthermore, the second limiting end can adapt to the spatial characteristics between the second curved inner wall and the first channel, and the V-shaped design can adapt to the contour of the storage space, so as to flexibly adjust the limiting angle, give full play to the limiting function without wasting space, and make the layout on the other side of the storage space more compact and reasonable.

[0072] Optionally, in order to improve the continuity of the storage space, the second arc-shaped limiting end 621 is connected to the second arc-shaped inner wall 512 , and the second straight limiting end 622 is connected to the first channel 3 .

[0073] like Figures 1 to 7 The earphone shown includes the wire hiding structure as described above, and the housing 1 is connected to a cover body 9 , and the cover body 9 is used to cover the storage space 5 .

[0074] The present invention provides a buffer space for the wire by cooperating with the storage space and the limit end. When different parts of the earphone are expanded or bent, the wire located in the storage space can adaptively move in the first channel or the second channel, thereby reducing the problem of solder joint pulling or wire breakage, allowing the wire to move internally without length constraints, thereby extending the service life of the wire.

[0075] Furthermore, as a preferred embodiment of the present invention but not a limitation, the wire hiding structure of the present invention can provide all-round protection for the wires in the earphones, and can prevent the wires in the earphones from being frequently pulled, squeezed and bumped. The S-shaped channel and storage space layout in the wire hiding structure, combined with the curved inner wall, limit ends and other settings, can effectively disperse stress and prevent the wires from being damaged due to uneven force or excessive pulling, greatly extending the overall service life of the earphones and reducing the need for frequent replacement due to wire problems.

[0076] Furthermore, as a preferred embodiment of the present invention but not a limitation, the hidden wire structure makes efficient use of the internal space of the earphone, so that the internal components can be reasonably arranged without increasing the overall volume of the earphone. This not only helps to achieve the miniaturization and lightweight design of the earphone, satisfying the user's pursuit of portability, but also makes the earphone more exquisite and beautiful, enhances the attractiveness of the product in appearance design, and makes the earphone have both appearance and portability, satisfying the user's experience needs.

[0077] The cover is used to cover the storage space. The cover can effectively block dust and sand from entering the storage space, prevent dust from accumulating on the surface of the wire and wearing away the insulation layer, or block the channel and affect the movement of the wire, ensure that the wire works stably in a clean environment, and further extend its service life. The cover fits tightly with the shell to form a relatively closed space. Even if the earphones are accidentally dropped, collided, or slightly squeezed, the cover can directly withstand the external impact, avoiding external force directly acting on the wire in the storage space, reducing the risk of damage to the wire due to accidents.

[0078] In terms of after-sales maintenance, if the components in the storage space need to be inspected, the internal structure can be easily accessed by simply removing the cover, which reduces the difficulty of maintenance and shortens the maintenance time. During the production process, the operator can quickly install the cover on the shell according to the assembly process, thereby improving production efficiency and reducing production costs.

[0079] like Figure 8 In the earphone shown, the cover body 9 is provided with a cover body cavity 91 , the structure of the cover body cavity 91 is symmetrically arranged with the structure of the storage space 5 , and the cover body 9 is detachably connected to the shell 1 .

[0080] The cover cavity and the storage space are symmetrically arranged, which opens up a double regular storage area for the wires inside the earphones. When the earphones face a greater expansion and deformation, the wires can not only be bent in an orderly manner in the original storage space, but also extend into the cover cavity, making full use of the extra space to buffer the change in wire length, ensuring that the wires are protected throughout the process, greatly improving the earphones' ability to adapt to complex deformations. At the same time, by flexibly guiding the wires to be reasonably distributed in two symmetrical spaces, the wires are avoided from being entangled and knotted, achieving efficient use and precise management of the wires, and further extending the life of the wires.

[0081] Optionally, in some embodiments, the cover is detachably connected to the housing, which provides great convenience for users and maintenance personnel. Users can easily remove the cover, quickly clean up the debris in the storage space and the cover cavity, or readjust the position of the wires to ensure that the headset is always in good working condition.

[0082] Optionally, in some embodiments, the cover body can be detachably connected to the shell by one or more methods such as magnetic connection, snap connection, fastener connection, mortise and tenon connection, and groove connection.

[0083] The earphones of the present invention utilize a hidden wire structure to reduce problems such as wire breakage, insulation layer damage or solder joint shedding, and can ensure the stability and durability of the sound quality transmission effect without affecting the appearance and internal space.

[0084] Optionally, in some embodiments, Figure 2 and Fig. 9 As shown, when the earphone is vertically arranged, the extension direction of the first channel is parallel to the extension direction of the second channel, and the angle α formed by the first channel and the horizontal plane is between 40-60 degrees.

[0085] Specifically, when the earphones are stationary, the wire naturally droops under the traction of gravity and gently falls to the bottom of the storage space along the channel, avoiding the formation of stress concentration points at the welding points and bends when the earphones are suspended vertically. During exercise, such as the up and down bumps during running and the rapid rotation of the head during aerobics, the wire will not generate torque due to complete horizontality due to the angle of the channel, causing outer skin wear and internal wire breakage, nor will it exceed the elastic limit due to vertical pulling. The evenly dispersed force greatly delays fatigue damage, fundamentally ensuring the long-term and stable operation of the wire and significantly extending the service life of the earphones.

[0086] Optionally, a first connecting line 11 is formed between the first limiting end and the arc midpoint of the second arc-shaped inner wall, and a second connecting line 12 is formed between the second limiting end and the arc midpoint of the first arc-shaped inner wall. The first connecting line and the second connecting line are parallel, and the first connecting line and the second connecting line are both parallel to the first straight inner wall and the second straight inner wall.

[0087] Specifically, the parallel arrangement of the first and second connecting lines means that the wire passing through the first channel will be firmly constrained by the relative position relationship between the first limiting end and the second curved inner wall during the process of extending and bending toward the second channel. Since the first connecting line is parallel to the key inner wall, the wire can only move along a predetermined path parallel to the connecting line, thus preventing the wire from tilting or deviating from the ideal trajectory in the storage space, ensuring that each bend is accurate and correct, and minimizing the risk of damage to the wire due to improper displacement. Similarly, the wire passing through the second channel can also be stably transitioned along a direction parallel to the second connecting line under the coordinated limitation of the second limiting end and the first curved inner wall, which fully guarantees the standardization and stability of the wire in the complex threading process.

[0088] Specifically, this design in which the connection line is parallel to the inner wall makes full use of the geometric space characteristics inside the earphone. This allows each area of ​​the storage space, whether close to the curved inner wall or the straight inner wall, to be optimally laid out according to the ideal direction of the wire. There will be no waste of space or wire congestion due to the confusion between the limit end and the inner wall, and every inch of space is reasonably utilized. In a limited earphone shell, the wires, acoustic components and other necessary parts can be compactly placed, which will help promote the development of earphones in the direction of miniaturization and lightweight, and meet users' growing demand for portable earphones.

[0089] Specifically, when the earphones are subjected to external impact, vibration, or frequent expansion and deformation, the parallel connection structure and the inner wall together provide strong mechanical support for the wire. The tension and torsion of the wire can be evenly distributed to each support point, that is, transmitted to the curved inner wall and the straight inner wall along the connection direction, avoiding stress concentration in a certain local area. For example, in sports scenes, when the user is exercising vigorously, the earphones are subjected to forces from multiple angles. The wire can still remain in place with this stable mechanical structure without displacement or entanglement, ensuring that the audio signal transmission is not disturbed, greatly enhancing the reliability of the earphones in complex usage environments.

[0090] Optionally, the wire width is close to the width of the first channel and the second channel, respectively, the distance between the first connecting line and the second straight inner wall is equal to the distance between the second connecting line and the first straight inner wall, the distance between the first connecting line and the second straight inner wall is between three-tenths and one-third of the distance between the first straight inner wall and the second straight inner wall, the distance between the second connecting line and the first straight inner wall is between three-tenths and one-third of the distance between the first straight inner wall and the second straight inner wall, and the distance between the first connecting line and the second connecting line is between one-third and four-tenths of the distance between the first straight inner wall and the second straight inner wall.

[0091] Specifically, the first connecting line and the second straight inner wall, as well as the second connecting line and the first straight inner wall, maintain a specific distance ratio, so that the storage space is finely divided in the horizontal dimension. When the wire passes from the first channel to the second channel, or in the opposite direction, there is just the right amount of reserved space on both sides, so that the wire will not rub or squeeze against the inner wall due to being too close, nor will the wire shake or deviate from the ideal path due to lack of effective support during the bending process due to being too far. This precise spatial adaptation ensures that the wire can stably and smoothly complete complex S-shaped bends regardless of whether it is flowing in the forward or reverse direction, making full use of the storage space and achieving efficient storage and protection of the wire.

[0092] Moreover, this distance setting allows the area formed between the straight inner wall and the connecting wire to be optimized according to the stress characteristics of the wire. For example, when the earphone expands and deforms, the wire is stretched, and these areas can provide appropriate buffer space to prevent the wire from directly hitting the inner wall, dispersing stress and further ensuring the life of the wire.

[0093] Specifically, the precise distance ratio provides excellent mechanical performance guarantee for the earphones when dealing with external forces. When the earphones are subjected to extrusion, collision or frequent expansion deformation, such as accidental collision scenarios during outdoor sports and daily commuting, the tension and torsion of the wires can be evenly and efficiently dispersed throughout the entire hidden wire structure based on the stable distance relationship between the components. Because the distance between the first and second connecting lines and between them and the straight inner wall has been finely adjusted, a stable mechanical support network is formed, so that the wires can remain in place under complex force environments without displacement or entanglement, ensuring the stability of audio signal transmission and greatly enhancing the reliability of the earphones under various working conditions.

[0094] Specifically, a stable and reasonable internal structure distance relationship plays a vital role in improving acoustic performance. When the wire moves in an orderly manner along the predetermined trajectory, it will not generate additional noise or murmurs due to shaking or collision caused by improper distance from the inner wall.

[0095] Furthermore, an assembling method of earphones, including the earphones as described above, is as follows: S1, passing one side of the wire 2 through one side of the first channel 3 or the second channel 4 into the storage space 5; When starting to assemble, the first thing to do is to select wires of appropriate specifications to ensure that they have good conductivity and flexibility to meet the subsequent use requirements of the headphones. The worker holds one end of the wire, accurately aligns it with the entrance of the first channel or the second channel, and gently pushes it so that the wire flows smoothly into the storage space along the inner wall of the channel.

[0096] S2, the wire 2 abuts against the limiting end 6, and the wire 2 is bent into an S shape; After the wire passes through the storage space, as the wire goes deeper, it is bent along the guidance of the limit end, gradually forming an S-shaped layout. For the first limit end and the second limit end set in a V shape, the wire is inserted into the V-shaped first limit end and the second limit end respectively to ensure that the wire does not deviate from the predetermined path during the bending process and stably abuts against the first limit end and the second limit end. During the bending process, it is ensured that the S-shaped bend not only fits the shape of the storage space, but also makes full use of the space, provides good buffering and protection for the wire, and effectively disperses the stress that may be borne during the subsequent use of the headphones.

[0097] S3, passing one side of the wire 2 through the other side of the first channel 3 or the second channel 4 out of the storage space 5; After completing the S-bend, the other side of the wire needs to pass through the other side of the first channel or the second channel to avoid problems such as jamming and entanglement at the exit. The length of the wire after passing through should be reasonable, which should not only meet the requirements of connecting with other components of the headset, but also should not be too long to cause the wire to be messy during subsequent use.

[0098] S4, cover the cover 9 on the surface of the shell 1.

[0099] After the wires are properly arranged in the storage space, check whether the inside of the cover cavity is clean and free of debris to ensure that there are no foreign objects that affect the subsequent performance of the headphones. Then, align the cover with the corresponding part on the shell according to the predetermined detachable connection method, such as snap-on connection, magnetic connection, etc., and gently press or approach to make the cover fit tightly with the shell. During the closing process, ensure good sealing so that the cover is completely covered on the shell surface.

[0100] The earphone assembly method of the present invention is simple and convenient, and the wire hiding structure can be used to quickly adjust the wire position and length, thereby avoiding misalignment, tangling, extrusion, etc. of the wire, and effectively ensuring the stability of the wire.

[0101] Embodiment 1 like Figures 1 to 9 A wire hiding structure shown includes a shell 1, wherein the shell 1 is provided with a first channel 3 for one end of a wire 2 to pass through, a second channel 4 for the other end of the wire 2 to pass through, and a storage space 5 located between the first channel 3 and the second channel 4, wherein the storage space 5 is provided with a limiting end 6, and when the wire 2 movably passes through or passes through the first channel 3 or the second channel 4, the limiting end 6 is used to keep the wire 2 bent and arranged in the storage space 5, and the storage space 5 is centrally symmetrically arranged, and the wire 2 is arranged in an S shape in the storage space.

[0102] The present invention provides a buffer space for the wire 2 by cooperating with the storage space 5 and the limit end 6. When different components of the earphone are expanded or bent, the wire 2 located in the storage space 5 can adaptively move in the first channel 3 or the second channel 4, thereby reducing the problem of welding point pulling or wire 2 breakage, allowing the wire 2 to move internally without length constraints, thereby extending the service life of the wire 2.

[0103] The storage space 5 is arranged between the neck ring 7 and the earpiece of the earphone, and when the neck ring expands and deforms, the wire 2 in the neck ring needs more wire 2 length to adapt to the expansion path of the neck ring, and the wire 2 of the neck ring can drive the wire 2 in the storage space 5 to move to the side close to the neck ring. At this time, the wire 2 switches from the bent storage state to the bent and contracted state. When the neck ring is reset, the expansion path of the neck ring is restored and shortened, and the wire 2 in the neck ring needs to shorten the wire 2 length to adapt to the neck ring. The wire 2 is synchronously reset under the drive of the limit end 6, so that the wire 2 can be stored in the storage space 5 and switch and restore from the bent and contracted state to the bent storage state.

[0104] Embodiment 2 The difference between the second embodiment and the first embodiment is that: The storage space is set between the neck ring 7 and the microphone rod 8 of the earphone. When the neck ring expands and deforms, the wire 2 in the neck ring needs more wire 2 length to adapt to the expansion path of the neck ring. The wire 2 in the neck ring can drive the wire 2 in the storage space 5 to move to the side close to the neck ring. At this time, the wire 2 switches from the bent storage state to the bent and contracted state. When the neck ring is reset, the expansion path of the neck ring is restored and shortened. The wire 2 in the neck ring needs to shorten the wire 2 length to adapt to the neck ring. The wire 2 is synchronously reset under the drive of the limit end 6, so that the wire 2 can be stored in the storage space 5 and switch from the bent and contracted state to the bent storage state.

[0105] When the microphone rod is bent and deformed, the wire 2 in the microphone rod needs more wire 2 length to adapt to the bending path of the microphone rod. The wire 2 of the microphone rod can drive the wire 2 in the storage space 5 to move to the side close to the microphone rod. At this time, the wire 2 switches from the bent and stored state to the bent and contracted state. When the microphone rod is reset, the bending path of the microphone rod is restored and shortened. The wire 2 in the microphone rod needs to shorten the wire 2 length to adapt to the microphone rod. The wire 2 is synchronously reset under the drive of the limit end 6, so that the wire 2 can be stored in the storage space 5 and switch from the bent and contracted state to the bent and stored state.

[0113] Furthermore, as a preferred embodiment of the present invention but not a limitation, the hidden wire structure makes efficient use of the internal space of the earphone, so that the internal components can be reasonably arranged without increasing the overall volume of the earphone.
