Description

Technical Field

[0001] This application relates to the technical field of headphones, and more particularly to a clip-on headphone. Background Technology

[0002] In the current headphone market, clip-on headphones, with their unique wearing method, allow audio playback without inserting into the ear, avoiding the ear canal discomfort that can occur with prolonged wear of traditional in-ear headphones, thus gaining increasing attention and favor from consumers. Currently, most clip-on headphones on the market use a soft rubber clip-on design. This is achieved through the elastic deformation of soft rubber or a combination of soft rubber and shape-memory metal, thus completing the clip-on wearing action. This soft rubber clip-on design is relatively easy to implement technically, with mature processes and low production costs, which is one of the important reasons for its mainstream adoption. However, this design also has several obvious drawbacks. Due to the low technical threshold, many manufacturers have adopted this design, resulting in minimal product differentiation and a lack of innovation and distinctiveness in appearance, making it difficult to meet consumers' demands for personalized products. From a wearing experience perspective, the clipping force of this design is difficult to precisely control. If the clipping force is too strong, prolonged wear will cause significant pain for the user, greatly affecting comfort; if the clipping force is too weak, the headphones are prone to falling off during daily activities, causing inconvenience. Despite manufacturers’ continuous efforts to optimize, the key issue of pain after prolonged wear remains unresolved, which to some extent limits the further development of this type of clip-on headphone.

[0003] Besides the mainstream forms mentioned above, some manufacturers in the industry have explored innovative ways to achieve ear-clamping wearing by using damping hinges. This form has significant advantages: its novel and unique appearance can attract consumers' attention; at the same time, users can freely adjust the wearing angle and tightness of the headphones according to their own ear characteristics, resulting in a high degree of adaptability and a more secure fit, effectively avoiding the problem of traditional soft rubber ear-clamping headphones easily falling off. However, damping hinge ear-clamping headphones have also encountered technical bottlenecks in their development. Among them, the difficulty of the hinge's electrical connection technology is a key factor restricting its development. Due to this technical difficulty, the electronic components of the headphones must be stacked and integrated on one side of the cavity, while the space utilization of the other side is relatively low. This unreasonable layout prevents the overall size of the product from being further reduced, thus failing to achieve extreme compactness. This not only affects the product's portability but also limits the product's design space to a certain extent, preventing it from fully showcasing its novel appearance advantages. Utility Model Content

[0004] The purpose of this application is to provide an ear clip-on earphone that can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On one hand, a clip-on earphone is provided, comprising: a first housing, a second housing, a connector, and a wire. The two ends of the connector are respectively connected to the first housing and the second housing, and the connector is rotatably connected to at least the first housing. A wire-passing structure is provided at the rotatable connection between the connector and the first housing. The wire is disposed inside the connector, one end of the wire extends into the second housing, and the other end of the wire can extend into the first housing through the wire-passing structure to electrically connect electrical components in the first housing and the second housing.

[0006] Furthermore, the end of the connector that connects to the first housing is provided with a rotating part, and the first housing is provided with a rotating groove that rotatably engages with the rotating part. A rotating assembly is provided between the rotating part and the first housing so that the rotating part can rotate and lock within the rotating groove.

[0007] Furthermore, the wire-passing structure includes a wire-passing groove formed in the rotating part, an inlet provided in the wire-passing groove facing the connector, and an outlet provided in the wire-passing groove away from the connector. One end of the wire passes through the inlet and extends along the groove wall of the wire-passing groove, and extends through the outlet into the first housing.

[0008] Furthermore, the bottom of the rotating groove is provided with a clearance opening, and one end of the wire can pass through the clearance opening and extend into the first housing.

[0009] Furthermore, the diameter of the clearance opening is larger than the diameter of the outlet opening, so that when the first housing rotates, the two inner walls of the clearance opening in the rotation direction never contact the wire.

[0010] Furthermore, the rotating assembly includes a damping plate mounted on the rotating part and a rotating shaft rotatably connected to the damping plate. The rotating shaft is keyed to the first housing, and the wire groove is concentrically arranged with the rotating shaft.

[0011] Furthermore, the first housing can rotate relative to the connector by an angle α to adjust the opening distance A between the first housing and the second housing, wherein 1.8mm≤A≤4.0mm and 30°≤α≤60°.

[0012] Furthermore, the electrical components include a circuit board assembly, a battery assembly, a speaker assembly, and a radio assembly. The circuit board assembly and the battery assembly are disposed within the first housing, and the speaker assembly and the radio assembly are disposed within the second housing. One end of the wire is connected to the circuit board assembly and the battery assembly, and the other end of the wire is connected to the speaker assembly and the radio assembly.

[0013] Furthermore, the connector includes a main body and an upper cover. The main body has a fitting groove for installing the wire, and the upper cover covers the main body to seal the fitting groove.

[0014] Furthermore, the second housing includes an upper housing portion integrally formed with the connector and a lower housing portion detachably mounted on the upper housing portion. The lower housing portion has a sound outlet on the side opposite to the upper housing portion. The ear clip-on earphone is worn behind the ear, and the sound outlet faces the ear canal opening.

[0015] Furthermore, the first housing includes a columnar main housing portion and side cover portions that are detachably installed at both ends of the main housing portion.

[0016] The beneficial effects of this application are as follows: Through the rotating connection design between the connector and the first shell, users can easily adjust the wearing angle and tightness of the headphones according to their own ear characteristics and usage scenarios, so that the headphones can fit the ears perfectly. This will not cause pain after wearing for a long time due to excessive clamping force, nor will they easily fall off due to insufficient clamping force, thus greatly improving the comfort and stability of users wearing them for a long time.

[0017] Meanwhile, the technical challenges of electrical connections at the rotation position were solved, avoiding the problem of low space utilization at the rotation point caused by unreasonable electrical connection layout. The wires are electrically connected through the internal connector and the wire-passing structure, making the overall structure of the headphones more compact and reasonable. It can minimize the product size while ensuring the integrity of functions, creating an extremely compact appearance that is convenient for users to carry and use, meeting the needs of modern consumers for portable electronic products.

[0021] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] like Figures 1-6As shown, this embodiment provides a clip-on earphone, including: a first housing 1, a second housing 2, a connector 3, and a wire 4. The two ends of the connector 3 are respectively connected to the first housing 1 and the second housing 2, and the connector 3 is at least rotatably connected to the first housing 1. A wire-passing structure is provided at the rotatable connection between the connector 3 and the first housing 1. The wire 4 is disposed in the connector 3, one end of the wire 4 extends into the second housing 2, and the other end of the wire 4 can extend into the first housing 1 through the wire-passing structure to electrically connect the electrical components in the first housing 1 and the second housing 2.

[0025] Based on the above scheme, connector 3, as a key connection and transmission component, is connected to the first housing 1 and the second housing 2 at both ends, and forms a rotatable connection with at least the first housing 1. This rotatable connection design gives the headphones flexible adjustment functions. Users can freely rotate the first housing 1 according to their own ear contours and usage needs to adjust the overall wearing angle and tightness of the headphones, thereby achieving a personalized and comfortable wearing experience. This effectively avoids the problems of pain or easy falling off caused by improper clamping force in traditional soft rubber ear clip designs.

[0026] To address the technical challenge of electrical connection at the rotation point, particularly suitable for the damped connection of the rotating shaft 502, this application incorporates a carefully designed wire-passing structure at the rotational connection between the connector 3 and the first housing 1. The wire 4 is cleverly housed inside the connector 3, with one end extending into the second housing 2 and connecting to electrical components therein; the other end extends smoothly into the first housing 1 via the wire-passing structure, achieving electrical connection with electrical components within the first housing 1. The wire-passing structure design fully considers the protection of the wire 4 and the stability of the electrical connection during rotation. While ensuring the connector 3 can rotate freely, it ensures that the wire 4 will not wear or break due to frequent rotation, thus guaranteeing stable transmission of electrical signals within the earphone. This solves the problem of unreasonable product layout and the inability to achieve extreme compactness caused by the difficulty of electrical connection in the damped shaft 502 design.

[0027] This application's clip-on earphone brings a series of significant and multi-dimensional benefits, successfully breaking through the limitations of existing technology and achieving a comprehensive upgrade in experience and performance. Traditional soft silicone clip-on earphones often face the dilemma of clamping force: too much clamping force causes pain after prolonged wear, while too little clamping force makes them prone to falling off, seriously affecting the user experience. However, the earphones of this application, through the rotating connection design of the connector 3 and the first shell 1, allow users to freely adjust the wearing angle and tightness according to their own ear contours and usage scenarios. Whether for long-term listening or use during exercise, it ensures a comfortable and stable fit to the ear, completely eliminating the problems of wearing discomfort and falling off. In existing clip-on earphones with damping hinge 502, the technical difficulties in the electrical connection of hinge 502 result in low space utilization at the tail end of hinge 502, leading to a bulky product size and poor portability. This application innovatively sets a wire-passing structure at the rotatable connection between the connector 3 and the first housing 1, hiding the wire 4 inside the connector 3 and achieving electrical connection through the wire-passing structure. While ensuring the stability of the electrical connection, it optimizes the internal space layout of the product, greatly reducing the size of the earphone, making it compact and exquisite in appearance, easy to carry, highlighting fashion and technology, and meeting the needs of modern consumers for exquisite and lightweight portable electronic products.

[0028] Furthermore, the end of the connector 3 connected to the first housing 1 is provided with a rotating part 301. The first housing 1 has a rotating groove that rotatably engages with the rotating part 301. A rotating assembly 5 is provided between the rotating part 301 and the first housing 1, allowing the rotating part 301 to rotate and lock within the rotating groove. The connector 3's end connected to the first housing 1 is specifically provided with the rotating part 301, and the first housing 1 has a corresponding rotating groove adapted to the rotating part 301. This structural design provides a specific movement space for the rotating part 301. The rotating assembly 5 between the rotating part 301 and the first housing 1 is the core component for realizing the rotation and locking functions. When a user needs to adjust the wearing angle or tightness of the headphones, applying a certain external force to the first shell 1 causes the rotating component 5 to allow the rotating part 301 to rotate smoothly within the rotating groove, thereby changing the position of the first shell 1 relative to the second shell 2. This allows for flexible adjustment of the overall wearing position of the headphones, specifically changing the opening distance between the first shell 1 and the second shell 2, i.e., the space between the first shell 1 and the second shell 2 for clamping the ear. Once the user has adjusted the headphones to a suitable wearing position, the rotating component 5 locks the first shell 1 in place, preventing accidental rotation due to slight external forces or its own weight during daily use, ensuring that the headphones always maintain a stable and comfortable wearing position.

[0029] In some embodiments, the wire-passing structure includes a wire-passing groove 3011 formed within the rotating part 301, an inlet 3012 located on the side of the wire-passing groove 3011 facing the connector 3, and an outlet 3013 located on the side of the wire-passing groove 3011 away from the connector 3. One end of the wire 4 passes through the inlet 3012, extends along the groove wall of the wire-passing groove 3011, and exits through the outlet 3013 into the first housing 1. The rotating part 301 is a key component for the rotatable connection between the connector 3 and the first housing 1, and the wire-passing groove 3011 formed inside it is the core space of the entire wire-passing structure. The inlet 3012 is located on the side of the wire-passing groove 3011 facing the connector 3, while the outlet 3013 is located on the side of the wire-passing groove 3011 away from the connector 3. This layout provides clear guidance for the direction of the wire 4. During headphone assembly, one end of the wire 4 is first led out from inside the connector 3, passing through the inlet 3012 and entering the wire channel 3011. Within the wire channel 3011, the wire 4 extends along the carefully designed channel wall. The channel wall not only provides physical support for the wire 4, preventing it from wobbling or tangling during rotation, but also guides the wire 4 along a specific path, ensuring its orderly arrangement within the limited space. Finally, the wire 4 exits the wire channel 3011 through the outlet 3013, smoothly extending into the first housing 1, where it establishes an electrical connection with the electrical components within the first housing 1.

[0030] During the use of the headphones, the cable guide structure functions effectively when the rotating part 301 rotates within the rotating groove. The cable guide groove 3011 rotates together with the rotating part 301, and the relative position of the wire 4 within the cable guide groove 3011 remains relatively stable. Due to the protection and guidance of the groove wall, the wire 4 is not subjected to excessive pulling, twisting, or wear due to the rotation of the rotating part 301, thereby ensuring the stability and reliability of the electrical connection.

[0031] Meanwhile, a clearance opening 103 is provided at the bottom of the rotating groove, through which one end of the wire 4 can extend into the first housing 1. The clearance opening 103 optimizes the internal spatial layout of the earphone. It cleverly utilizes the space at the bottom of the rotating groove to create an independent channel for the wire 4, preventing it from interfering with or tangling with other components. This not only makes the internal structure of the earphone more compact and orderly but also facilitates assembly and maintenance. During assembly, workers can more easily connect the wire 4 through the clearance opening 103, improving assembly efficiency; during maintenance, problems with the wire 4 can be located and addressed more quickly, reducing maintenance difficulty and cost.

[0032] It is worth noting that the diameter of the clearance opening 103 is larger than the diameter of the cable outlet 3013, so that when the first housing 1 rotates, the two inner walls of the clearance opening 103 in the rotation direction never contact the wire 4. This design advantage is fully demonstrated when the user uses the headphones and the first housing 1 rotates relative to the second housing 2. Because the diameter of the clearance opening 103 is larger than that of the cable outlet 3013, a sufficient safety gap is formed between the two inner walls of the clearance opening 103 and the wire 4 in the rotation direction. No matter which direction the first housing 1 rotates or the magnitude of the rotation, the inner wall of the clearance opening 103 will not contact the wire 4. The wire 4, within the channel formed by the cable groove 3011 and the clearance opening 103, can maintain a stable connection state unaffected by rotation, and importantly, will not be disturbed by external forces such as friction, compression, or jamming from the inner wall of the clearance opening 103, thus maintaining a stable physical state and electrical connection performance.

[0033] Optionally, the rotating assembly 5 includes a damping plate 501 mounted on the rotating part 301 and a rotating shaft 502 rotatably connected to the damping plate 501. The rotating shaft 502 is keyed to the first housing 1, and the wire groove 3011 is concentrically arranged with the rotating shaft 502. The rotating assembly 5 consists of the damping plate 501 mounted on the rotating part 301 and the rotating shaft 502 rotatably connected to the damping plate 501. The rotating shaft 502 is fixed to the first housing 1 by a key connection. When the user needs to adjust the wearing angle or state of the headphones, an external force is applied to rotate the first housing 1 relative to the rotating part 301. At this time, since the damping plate 501 is rotatably connected to the rotating shaft 502, the rotating part 301 will drive the damping plate 501 to rotate around the rotating shaft 502. The damping plate 501 generates a certain damping force during rotation. This damping force provides just the right amount of rotational resistance, preventing the rotation from being too easy and causing instability in the earphones, while also preventing excessive resistance from making rotation difficult. This allows users to precisely and smoothly control the rotation amplitude and flexibly adjust the earphone wearing status.

[0034] Meanwhile, the ingenious design of the wire channel 3011 being concentric with the rotating shaft 502 plays a crucial role during rotation. One end of the wire 4 extends from the connector 3, enters the wire channel 3011 through the inlet 3012, extends along the channel wall, exits through the outlet 3013, and then enters the first housing 1 through the clearance opening 103. Because the wire channel 3011 is concentric with the rotating shaft 502, when the rotating part 301 rotates around the rotating shaft 502, the wire channel 3011 rotates synchronously with the rotating part 301, and the relative position of the wire 4 within the wire channel 3011 changes little and is controllable. The wire 4 can always move smoothly with the rotation of the rotating part 301 under the protection and guidance of the wire channel 3011, without being subjected to excessive pulling, twisting, or tangling due to rotation, thus ensuring the stability of the electrical connection.

[0035] The first housing 1 can rotate relative to the connecting member 3 by an angle α to adjust the opening distance A between the first housing 1 and the second housing 2, wherein 1.8mm ≤ A ≤ 4.0mm and 30° ≤ α ≤ 60°. Since the rotation angle range of the first housing 1 relative to the connecting member 3 is preset to 30° ≤ α ≤ 60°, within this angle range, as the rotation angle α changes, the relative position between the first housing 1 and the second housing 2 changes, thus causing the opening distance A to change accordingly within the range of 1.8mm ≤ A ≤ 4.0mm. For example, when the user rotates the first housing 1 clockwise, as the rotation angle α gradually increases, the first housing 1 and the second housing 2 move further apart, and the opening distance A increases accordingly; conversely, when the user rotates the first housing 1 counterclockwise, as the rotation angle α gradually decreases, the opening distance A decreases accordingly. For users with smaller ears, the rotation angle can be adjusted to reduce the opening gap, allowing the headphones to fit more snugly against the ear and preventing them from loosening and falling out. For users with larger ears, the rotation angle can be increased to widen the opening gap, preventing excessive pressure on the ear and reducing discomfort. This personalized adjustment function allows each user to find the most suitable wearing method, greatly improving wearing comfort and enabling users to comfortably wear headphones to enjoy music or other audio content for extended periods.

[0036] Furthermore, when the opening gap A is within a suitable range, the headphones can better seal the ear canal, forming a relatively enclosed audio space. Within an opening gap range of 1.8mm-4.0mm, the headphones can effectively block external noise interference, allowing users to be more immersed in a pure audio world. At the same time, good sealing also improves the headphones' low-frequency response, making the bass in music deeper and more powerful, bringing users a richer and fuller audio experience. Users can flexibly adjust the opening gap according to different usage scenarios, such as quiet environments or noisy public places, to obtain the best audio effect and noise isolation performance.

[0037] Generally, the electrical components include a circuit board assembly 7, a battery assembly 6, a speaker assembly 8, and a microphone assembly 9. The circuit board assembly 7 and the battery assembly 6 are disposed within the first housing 1, and the speaker assembly 8 and the microphone assembly 9 are disposed within the second housing 2. One end of the wire 4 is connected to the circuit board assembly 7 and the battery assembly 6, and the other end of the wire 4 is connected to the speaker assembly 8 and the microphone assembly 9. The electrical components mainly encompass the circuit board assembly 7, the battery assembly 6, the speaker assembly 8, and the microphone assembly 9. The circuit board assembly 7, as the "brain" of the headphones, integrates various electronic circuits and chips, responsible for processing audio signals, controlling various headphone functions, and coordinating the operation between various components. The battery assembly 6 provides stable power support for the entire headphones, ensuring continuous normal operation. The speaker assembly 8 is a key component that converts electrical signals into sound, emitting sound through vibration to provide the user with an auditory experience. The microphone assembly 9 is used to receive external sound signals, enabling functions such as calls and recording.

[0038] In terms of layout, the circuit board assembly 7 and battery assembly 6 are cleverly arranged inside the first housing 1, while the speaker assembly 8 and receiver assembly 9 are housed inside the second housing 2. The wire 4 plays a crucial role, with one end tightly connected to the circuit board assembly 7 and battery assembly 6 inside the first housing 1, and the other end extending to the second housing 2, connecting to the speaker assembly 8 and receiver assembly 9. This connection method allows power to be stably transmitted from the battery assembly 6 to each component via the wire 4. Simultaneously, the audio signal processed by the circuit board assembly 7 can be accurately transmitted to the speaker assembly 8 for playback, and the sound signal received by the receiver assembly 9 can be promptly fed back to the circuit board assembly 7 for processing.

[0039] The design of the second housing 2, which houses only the speaker assembly 8 and the receiver assembly 9, is based on in-depth consideration of the acoustic cavity characteristics and wearing comfort. The acoustic cavity is a crucial space for the speaker to produce sound, and its size directly affects sound propagation and sound quality. By accommodating only these two components in the second housing 2, the acoustic cavity volume can be minimized. During headphone wear, a smaller acoustic cavity volume reduces pressure on the concha. The concha is a sensitive and limited space in the ear; an excessively large acoustic cavity volume can cause noticeable pressure in this area, affecting wearing comfort. By reducing the acoustic cavity volume, while ensuring that the speaker assembly 8 can produce sound normally and provide good sound quality, pressure on the concha is effectively reduced, making it more comfortable and relaxed for the user.

[0040] In some embodiments, the connector 3 includes a main body 302 and a top cover 303. The main body 302 has a fitting groove for mounting the wire 4, and the top cover 303 covers the main body 302 to seal the fitting groove. In daily use, headphones inevitably come into contact with various complex environments, such as sweat during exercise, outdoor rain, and dust in the air. Without effective protective measures, these factors can easily damage the wire 4, leading to insulation damage, internal core wire breakage, or oxidation, which in turn causes signal transmission interruption, short circuits, noise, and other problems, seriously affecting the normal use of the headphones. The connector 3 design of this application, by placing the wire 4 in the fitting groove and sealing it, can effectively prevent the intrusion of dust and moisture, preventing the wire 4 from being corroded and damaged. At the same time, the top cover 303 also acts as a buffer and isolation, reducing friction and collision between the wire 4 and other components, extending the service life of the wire 4, and reducing the frequency and cost of headphone repairs due to wire 4 failure.

[0041] During the headphone assembly process, the fitting groove of the main body 302 provides a clear installation position for the wire 4, allowing operators to quickly and accurately place the wire 4 into the groove, improving assembly efficiency. The fitting method between the upper cover 303 and the main body 302 is simple and easy, requiring no complicated tools or operating procedures, further simplifying the assembly process and reducing production costs. For later maintenance, if it is necessary to inspect or replace the wire 4, simply open the upper cover 303 to easily access the wire 4 in the fitting groove without disassembling the entire headphone structure, greatly saving maintenance time and costs. This design, which facilitates assembly and maintenance, helps improve headphone production efficiency and after-sales service quality, bringing convenience to both enterprises and users.

[0042] Specifically, the second housing 2 includes an upper housing portion 201 integrally formed with the connector 3, and a lower housing portion 202 detachably mounted on the upper housing portion 201. The lower housing portion 202 has a sound outlet 203 on its side opposite to the upper housing portion 201, wherein the ear-clip earphone is worn behind the ear, and the sound outlet 203 faces the ear canal opening. The upper housing portion 201 and the connector 3 are integrally formed, a design that creates a tightly connected whole, resulting in high structural strength and stability. The integral molding process typically employs injection molding or similar methods. During manufacturing, the materials of the connector 3 and the upper housing portion 201 are formed in one piece, avoiding gaps and loosening issues that may exist in traditional assembly methods, ensuring a firm and reliable connection between the two. The lower housing portion 202 is detachably mounted on the upper housing portion 201, a design that facilitates the assembly, maintenance, and upgrades of the earphone. The lower shell 202 and the upper shell 201 are typically secured by common detachable connection structures such as clips or threads. Users or maintenance personnel can easily remove the lower shell 202 from the upper shell 201 or reinstall it as needed. A sound outlet 203 is located on the side of the lower shell 202 opposite to the upper shell 201; this is the key channel for headphone sound output. When the headphones are worn in the ear, the sound outlet 203 is precisely oriented towards the ear canal opening. This design allows the sound emitted by the speaker assembly 8 to be directly and efficiently transmitted into the ear canal, reducing sound scattering and loss during propagation, thus providing users with a clear and full audio experience.

[0043] Furthermore, the first housing 1 includes a columnar main housing portion 101 and side cover portions 102 that are detachably installed at both ends of the main housing portion 101. The design of the main housing portion 101 and the detachable side cover portions 102 in the first housing 1 greatly facilitates the installation and subsequent maintenance of the internal components of the earphone. During the production assembly process, workers can easily place core components such as the circuit board assembly 7 and the battery assembly 6 into the main housing portion 101. Because the main housing portion 101 is columnar and has a regular internal space, the placement and positioning of components are more accurate and convenient. After the internal components are installed, the side cover portions 102 are then installed at both ends of the main housing portion 101 to complete the overall assembly. This step-by-step assembly method improves production efficiency and reduces assembly difficulty.

[0044] When the headphones malfunction during use, or when internal components need to be upgraded or replaced, the detachable side cover 102 design allows maintenance personnel to quickly and easily open the first housing 1 and directly access the internal components. Unlike traditional one-piece housings, which require complex tools for disassembly, this significantly shortens maintenance time and reduces maintenance costs. For example, if the battery pack 6 experiences power degradation or damage, maintenance personnel can easily replace the battery pack 6 by simply removing the side cover 102, allowing the headphones to quickly return to normal operation.

[0045] It's important to note that the damping torque between the hinge 502 and the damping plate 501 is designed to be between 0.5N and 2.6N. This torque level has been rigorously tested, ensuring moderate force and a smooth feel. Designing the damping torque between 0.5N and 2.6N precisely adapts to the needs of clip-on headphones in various usage scenarios. During daily wear and headphone adjustment, the lower torque (close to 0.5N) allows users to easily rotate the headphone components without excessive effort. For example, when unfolding the headphones from their stored state and putting them on, the operation is natural and smooth, without feeling strained due to excessive torque or difficulty adjusting the position due to insufficient torque. In scenarios requiring relatively stable headphone positions, such as during exercise, the higher torque (close to 2.6N) ensures that the headphone components do not rotate freely due to body movements, always remaining in the user-set, comfortable position and providing a stable wearing experience. This torque design, which can be flexibly adjusted according to different scenarios, allows users to experience a comfortable and convenient operation when using the headphones, greatly improving the ease of use of the product.
