Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically to a spring-loaded ear-hook Bluetooth headphone. Background Technology

[0002] With the iteration of consumer electronics technology and the upgrading of user needs, Bluetooth headphones have evolved from early single-function products into mainstream audio devices with mature technology and diverse experiences. The market landscape continues to differentiate, giving rise to several subcategories such as clip-on, ear-hook, in-ear, and over-ear headphones, based on wearing scenarios, usage needs, and comfort. Among them, clip-on and ear-hook headphones, with their feature of not needing to be inserted into the ear canal, have become popular choices for scenarios such as sports, commuting, and office work.

[0003] Currently, there are four main types of ear-hook implementations for ear-hook headphones:

[0004] 1. Utilizing the elastic properties of soft rubber material, it conforms to the earlobe through natural deformation during wear;

[0005] 2. It adopts a composite structure of memory steel wire and soft rubber, combining the toughness of memory steel wire with the skin-friendliness of soft rubber to balance support and fit.

[0006] 3. By utilizing the micro-deformation design of the hard plastic material, basic fit is provided while ensuring structural stability;

[0007] 4. It uses only memory steel wire as the core support structure and relies on the elastic deformation of the steel wire itself to achieve the fixing of the ear.

[0008] In the fourth type of ear-hook design that relies solely on memory wire, the diameter of the memory wire is usually controlled at around 0.8mm due to the limitations of the elastic deformation force of the memory wire and the lightweight design of the product. This results in the support force of the memory wire being concentrated on the local area behind the ear when the headphones are worn for a long time, which can easily cause pressure on the skin and cartilage behind the ear, leading to discomfort such as soreness and pressure in the ear. Utility Model Content

[0009] In order to overcome the problem that existing ear-hook headphones, which rely solely on memory steel wires to achieve the ear-hook function, can cause discomfort such as soreness and pressure in the ear after prolonged wear, this utility model provides a spring-loaded ear-hook Bluetooth headset.

[0010] The technical solution of this utility model is as follows:

[0011] A spring-loaded ear-hook Bluetooth headset includes a headset body and an ear-hook portion. The ear-hook portion includes a memory metal wire and a coil spring. One end of the memory metal wire is connected to the headset body, and the coil spring is sleeved outside the memory metal wire. Both the coil spring and the memory metal wire are bent and shaped into an arc-shaped ear-hook structure.

[0012] As a preferred embodiment of this utility model, the coil spring includes a transition portion near the main body of the earphone and an abutment portion connected to the transition portion. After the transition portion is connected to the main body of the earphone, it forms an ear hook support structure. The ear hook support structure passes around the upper ear wheel when worn, and the abutment portion abuts against the back of the auricle when worn.

[0013] As a preferred embodiment of this utility model, the end of the earphone body connected to the memory metal wire is provided with a connecting part, the end face of the transition part abuts against the end face of the connecting part, and the diameter of the end face of the transition part is not greater than the diameter of the end face of the connecting part.

[0014] As a preferred embodiment of this utility model, the diameter of the transition portion gradually decreases in the direction away from the headphone body until it is the same as the diameter of the abutment portion.

[0015] As a preferred embodiment of this utility model, the wire diameter of the coil spring is 0.3mm-0.7mm, the diameter of the abutting part is 1.3-2mm, and the end face diameter of the transition part is 3.5-5mm.

[0016] As a preferred embodiment of this utility model, one end of the memory metal wire near the main body of the earphone passes through the coil spring and is provided with a first connector. An opening is provided on the connecting part for the first connector to pass through, and a second connector connected to the first connector is provided inside the connecting part.

[0017] As a preferred embodiment of this utility model, the end of the coil spring is provided with an assembly auxiliary component.

[0018] In a preferred embodiment of this utility model, the spacing between the coils of the coil spring is 0.

[0019] As a preferred embodiment of this utility model, the coil spring is made of piano wire.

[0020] As a preferred embodiment of this utility model, the surface of the coil spring is provided with a metal plating layer.

[0021] As a preferred embodiment of this utility model, the diameter of the memory metal wire is 0.3m-0.8mm.

[0022] As a preferred embodiment of this utility model, the memory metal wire is a memory steel wire.

[0023] As a preferred embodiment of this utility model, the main body of the earphone is provided with a speaker module, a circuit board and a battery.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. The ear hook uses a combination of fine memory metal wire and thick coil spring, which increases the contact area between the ear hook and the auricle, transforming concentrated pressure into evenly distributed contact force. This not only improves wearing stability but also disperses the support pressure when the wearer wears the headphones, improving wearing comfort and preventing a single memory metal wire from directly pressing on the local area behind the ear, effectively alleviating discomfort such as soreness and pressure pain from prolonged wear.

[0026] 2. By utilizing the elastic properties of the spring coil itself and the memory metal wire to form a synergistic deformation, the adaptability of the ear hook is improved, better fitting the ear size and shape of different wearers, ensuring wearing comfort and versatility;

[0027] 3. By applying the transition part and the abutment part of the coil spring to the upper ear helix and the back of the ear respectively, a multi-point fixing structure is formed, which effectively prevents the earphone from slipping off when the head shakes or moves; at the same time, the smooth size transition of the transition part allows the force during wearing to be evenly transmitted from the main body of the earphone to the ear hook, reducing the local pressure concentration caused by structural abrupt changes, making the product structure simpler and smoother, avoiding abrupt size differences, and reducing structural gaps.

[0028] 4. By attaching auxiliary parts to the end of the coil spring to wrap or cover the sharp end of the coil spring, the sharp end of the coil spring is prevented from contacting the skin behind the ear when wearing, thus improving the wearing experience; the coil spring made of metal (such as piano wire) can be combined with metal plating to present different lusters such as bright and matte, and can also create special colors such as rose gold and gunmetal gray, enhancing the metal's technological feel and aesthetics.

[0039] like Figures 1 to 3As shown, an embodiment of this utility model provides a spring-loaded ear-hook Bluetooth headset, including a headset body 1 and an ear-hook 2. The ear-hook 2 includes a memory metal wire 21 and a coil spring 22. One end of the memory metal wire 21 is connected to the headset body 1. The coil spring 22 is sleeved on the outside of the memory metal wire 21. Both the coil spring 22 and the memory metal wire 21 are bent and shaped into an arc-shaped ear-hook structure. When worn, the coil spring 22 passes around the upper auricle of the wearer's auricle and abuts against the back of the wearer's auricle. In this embodiment, the ear hook 2 retains the high toughness and deformation recovery capability of the memory metal wire 21, providing core support for the ear hook 2 and ensuring that it is not easily deformed during wear. The ear hook 2 uses a smaller diameter memory metal wire 21 in combination with a larger diameter coil spring 22, which increases the contact area between the ear hook 2 and the auricle, transforming concentrated pressure into a uniformly distributed contact force. This not only improves wearing stability but also disperses the support pressure when the wearer wears the headphones, improving wearing comfort and preventing the single memory metal wire 21 from directly pressing on the local area behind the ear, effectively alleviating discomfort such as soreness and pressure pain from prolonged wear. The elastic properties of the spring coil spring 22 and the memory metal wire 21 form a synergistic deformation, improving the adaptability of the ear hook 2 and better fitting the ear size and shape of different wearers, ensuring wearing comfort and versatility. The arc-shaped design of the coil spring 22 fits the upper helix and the curve of the back of the ear, enhancing wearing stability and preventing sharp edges from contacting the skin, thus improving the wearing experience.

[0040] like Figures 1 to 3 As shown, in one embodiment, the coil spring 22 includes a transition portion 221 near the headphone body 1 and an abutment portion 222 connected to the transition portion 221. After the transition portion 221 is connected to the headphone body 1, it forms an ear hook support structure 3. The ear hook support structure 3 passes around the upper ear helix when worn, and the abutment portion 222 abuts against the back of the ear when worn. The transition portion 221 of the coil spring 22 provides support at the upper ear helix, and the abutment portion 222 enhances the fit on the back of the ear. The two work together to form multi-point fixation, preventing the headphones from slipping off due to head shaking when worn.

[0041] Furthermore, such as Figures 1 to 4As shown, the end of the earphone body 1 connected to the memory metal wire 21 is provided with a connecting part 11. The end face of the transition part 221 abuts against the end face of the connecting part 11, and the diameter of the end face of the transition part 221 is equal to or slightly smaller than the diameter of the end face of the connecting part 11, making the transition between the earphone body 1 and the coil spring 22 smoother. Specifically, the diameter of the transition part 221 gradually decreases in the direction away from the earphone body 1 until it is the same as the diameter of the abutting part 222, thus forming a smooth dimensional transition. This allows the force during wearing to be evenly transmitted from the earphone body 1 to the ear hook 2, reducing local pressure concentration caused by structural abrupt changes. At the same time, the smooth diameter transition makes the product structure simpler and smoother, avoiding abrupt dimensional differences, improving the product's aesthetics, reducing structural gaps, lowering the probability of dust and sweat intrusion, and extending service life.

[0042] In one embodiment, the coil spring 22 is preferably made of piano wire. Piano wire has high strength, high elastic limit, and good fatigue resistance. Using piano wire as the material for the coil spring 22 ensures that the coil spring 22 maintains good elasticity and stability during repeated deformation, effectively extending the service life of the coil spring 22, thereby improving the reliability and durability of the headphones, reducing headphone malfunctions caused by damage to the coil spring 22, and also giving the headphones a technological and metallic feel, meeting users' aesthetic demands. Of course, in other embodiments, the coil spring 22 can also be made of other metal / plastic materials with high strength, high elastic limit, and good fatigue resistance; this invention does not limit this.

[0043] In one embodiment, the diameter of the memory metal wire 21 is 0.3mm-0.8mm, meeting the product's lightweight requirements and avoiding additional weight; at the same time, it retains the core toughness of the memory metal wire 21, ensuring that the ear hook 2 is not easily deformed and maintains stable support. The spacing between the coils of the coil spring 22 is 0, which completely avoids the problem of hair getting caught when wearing the ear, improving ease of use. The wire diameter of the coil spring 22 is 0.3mm-0.7mm, comprehensively considering the elasticity, strength, and space occupation of the coil spring 22; the thinner wire diameter can increase the flexibility of the coil spring 22 to a certain extent, making it easier to deform, thereby better adapting to the ear shape of different wearers and providing a comfortable wearing experience; at the same time, while ensuring that the coil spring 22 has sufficient strength, the weight and volume of the headphones will not be increased due to excessive wire diameter, ensuring the lightweight and compactness of the headphones. The diameter of the abutment portion 222 is 1.3-2mm, and the end face diameter of the transition portion 221 is 3.5-5mm. The end face diameter of the transition portion 221 and the diameter of the abutment portion 222 form a reasonable difference, which avoids discomfort caused by abrupt size changes and improves the stability of the upper ear helix support through the larger diameter of the transition portion 221. The moderate diameter of the abutment portion 222 balances fit and weight. In particular, the larger diameter of the transition portion 221 increases the contact area of ​​the upper ear helix, and the moderate diameter of the abutment portion 222 ensures the fit on the back of the ear, further dispersing local pressure and enhancing the comfort experience.

[0044] like Figures 2 to 4 As shown, in one embodiment, the end of the memory metal wire 21 near the headphone body 1 passes through the coil spring 22 and is provided with a first connector 211. An opening 111 is provided on the connecting part 11 for the first connector 211 to pass through, and a second connector connected to the first connector 211 is provided inside the connecting part 11. By passing the first connector 211 of the memory metal wire 21 through the opening 111 of the connecting part 11 and mating it with the second connector of the connecting part 11, a mechanical locking structure is formed, allowing the memory metal wire 21 to be firmly connected to the headphone body 1, preventing it from falling off or loosening due to deformation or shaking during wear. The assembly method of the first connector 211 and the second connector provides a stable force support point for the memory metal wire 21, ensuring its toughness and deformation recovery ability are fully utilized, while avoiding stress concentration at the connecting part 11, extending the product's service life. At the same time, the first connector 211 and the second connector adopt a standardized design, facilitating precise assembly during the production process, reducing assembly errors, ensuring product consistency, and providing convenience for subsequent maintenance and component replacement.

[0045] like Figures 1 to 3As shown, in one embodiment, the end of the coil spring 22 is provided with an assembly auxiliary member 23 to wrap or cover the sharp ends of the coil spring 22 and the memory metal wire 21. The assembly auxiliary member 23 can fix the ends of the coil spring 22 and the memory metal wire 21 together to prevent the coil spring 22 from falling off the memory metal wire 21, and can also prevent the sharp ends of the coil spring 22 and the memory metal wire 21 from contacting the skin behind the ear when worn, thus improving the wearing experience.

[0046] Furthermore, the assembly aid 23 is a spherical or arc-shaped elongated structure, and its size is slightly larger than the end diameter of the coil spring 22. The spherical structure has a small contact area but distributes force evenly, avoiding additional localized pressure. Its rounded shape naturally conforms to the skin behind the ear, balancing comfort and scratch resistance, while its compact size does not compromise the product's lightweight design. The arc-shaped elongated structure has a higher degree of conformity to the ear's curve, increasing the contact area with the skin, further dispersing pressure, and extending the protection range to avoid potential scratches around the coil end, thus accommodating users with different ear shapes. In addition, both the spherical and arc-shaped elongated structures employ a cornerless design, completely eliminating the risk of sharp ends, and their simple shape does not compromise the overall aesthetics of the product, balancing practicality and visual appeal. Of course, in other embodiments, the assembly aid 23 may also adopt other cornerless structures; this invention does not limit this.

[0047] In one embodiment, the assembly aid 23 is made of soft rubber or plastic. A soft rubber assembly aid 23 is soft and elastic, providing a gentle touch against the skin and avoiding the discomfort caused by friction from hard materials, making it suitable for prolonged wear. Simultaneously, the micro-elasticity of soft rubber conforms to the contours of the ear, further dispersing contact pressure and cushioning slight movement during wear, thus improving stability. A plastic assembly aid 23 has moderate hardness, allowing it to be stably fixed to the end of the spring coil, preventing it from easily falling off due to deformation or compression, and maintaining its protective effect even after long-term use. Furthermore, plastic is lightweight, not adding extra burden to the headphones, and its mature processing technology and controllable cost make it suitable for mass production, ensuring product cost-effectiveness. Of course, in other embodiments, the assembly aid 23 can also be made of other materials, and this invention does not limit this.

[0048] In one embodiment, the surface of the coil spring 22 is provided with a metal plating layer, which can serve to prevent rust and corrosion, enhance the metallic feel, and increase surface smoothness. As everyday wearable devices, headphones are easily exposed to sweat, moisture, and acidic or alkaline substances in the air (such as sebum secreted by the body and pollutants in the environment). If the coil spring 22 is directly exposed, it is prone to oxidation or electrochemical corrosion. A metal plating layer (such as a nickel plating layer, zinc plating layer, or alloy plating layer) can form a dense barrier on the metal surface, isolating the external corrosive medium from contact with the metal substrate, preventing the coil spring 22 from weakening due to rust, losing elasticity, or even breaking, thereby significantly extending the lifespan of the spring and the entire headphone. The metal plating layer can be electroplated to achieve different gloss levels (such as bright, matte, or frosted textures) or to impart special metallic colors (such as rose gold or gunmetal gray), enhancing the technological and metallic feel of the headphones and meeting users' aesthetic demands. In addition, the coil spring 22 may have surface defects such as burrs and scratches during the processing, while the plating (especially the electroplating layer) can make the surface smoother through filling and polishing, avoiding scratching the skin of the ear when wearing it; at the same time, the smooth surface can also reduce friction and snagging with hair and clothing, improving the convenience of use.

[0049] In one embodiment, the memory metal wire 21 is a memory steel wire. Memory steel wire possesses excellent toughness and shape memory properties, allowing it to quickly recover its original curved ear hook structure even after repeated bending. It is not easily deformed during long-term wear, providing durable and reliable core support for the ear hook 2. While maintaining high structural strength, the memory steel wire can achieve a thin wire diameter (e.g., 0.3mm-0.8mm), meeting the mechanical requirements of ear hook support without increasing the overall weight of the headphones, ensuring a lightweight wearing experience. Simultaneously, the memory steel wire is wear-resistant and corrosion-resistant, able to withstand minor impacts and friction during daily use. It also exhibits strong resistance to sweat and temperature changes, making it less prone to breakage and rust with long-term use, extending the product's lifespan. Furthermore, the processing technology for memory steel wire is mature, allowing precise control of parameters such as wire diameter and hardness, facilitating mass production. Its stable elastic deformation characteristics can adapt to different ear shapes, balancing support and fit. Of course, in other embodiments, the memory metal wire 21 can also be made of other materials, and this invention does not limit this.

[0050] like Figure 4 , Figure 5As shown, in one embodiment, the housing 12 of the earphone body 1 houses a speaker module 13, a circuit board 14, and a battery 15. Both the speaker module 13 and the battery 15 are electrically connected to the circuit board 14. A speaker hole 121 is provided on the housing 12 of the earphone body 1 at the position corresponding to the speaker module 13. It should be noted that this embodiment does not involve the design of the internal circuitry of the ear-hook Bluetooth earphone; therefore, this embodiment will not elaborate on it. In other embodiments, the earphone body 1 can also be equipped with microphone modules, charging modules, and other functional modules according to actual needs, adapting to the functional requirements of different usage scenarios and improving product versatility. This utility model does not impose any limitations on this.

[0051] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
