Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, specifically to a spring-loaded clip-on Bluetooth headset and its case. Background Technology

[0002] Bluetooth headsets have matured significantly and rapidly diversified into various market segments. Clip-on and over-ear headphones are the most common types. Currently, there are three main ways clip-on headphones achieve this: one is through the elastic deformation of soft rubber, the second is through a combination of shape memory metal and soft rubber, and the third is through the micro-deformation of hard rubber.

[0003] Among them, ear-clamping headphones that achieve elastic deformation by combining shape memory metal and soft rubber are exemplified by Chinese utility model patent CN119545232A, which discloses an ear-clamping headphone. This headphone includes two earpieces, a connecting part, and a metal spring. The two earpieces are connected to the two ends of the connecting part, and the metal spring is inserted into the connecting part. The two ends of the metal spring extend towards the two earpieces and are correspondingly inserted into them. The metal spring has two states: a static straight state and a static bent state. The metal spring has at least two trigger points. Pressing one trigger point causes the metal spring to deform to a static straight state, thereby causing the two earpieces to move towards each other to form an ear-clamping position. Pressing the other trigger point causes the metal spring to deform to a static bent state, thereby causing the two earpieces to move in opposite directions, allowing the ear-clamping headphones to be removed from the ears.

[0004] While the aforementioned clip-on earphones achieve elastic deformation and ear clamping through metal springs and soft rubber, the metal springs are prone to fatigue. This means that with repeated deformation, the performance of the metal springs gradually declines, making it difficult to maintain their original elasticity and stability, thus resulting in a shorter lifespan for the entire earphone. After prolonged use, due to fatigue and performance degradation of the metal springs, the earphones tend to loosen, not only reducing their secure fit on the ears and potentially causing them to slip off, but also decreasing user comfort and impacting the overall user experience and evaluation of the earphone product. Furthermore, both earpieces contain electrical components that require wiring for electrical connection. This wiring temporarily occupies internal space in the connection area, limiting the optimization of the connection structure. Utility Model Content

[0005] In order to overcome the problems of easy fatigue of metal springs, short service life and the influence of wiring on the structural optimization of existing clip-on earphones, this utility model provides a spring-loaded clip-on Bluetooth earphone and earphone case.

[0006] The technical solution of this utility model is as follows: In a first aspect, this utility model provides a spring-loaded clip-on Bluetooth headset, comprising: The earphone body and the earphone clamp are connected at one end. The earphone clamp is a spring. The spring is bent and shaped into an arc or U-shape to form an ear clamping space. The two ends of the spring move closer or further apart through deformation. The earphone body contains a speaker module, a circuit board and a battery.

[0007] As a preferred embodiment of this utility model, the other end of the earphone clamp is provided with a mounting accessory.

[0008] In a preferred embodiment of this utility model, the spring component is a coil spring.

[0009] As a preferred embodiment of this utility model, the coil spring is made of metal.

[0010] As a preferred embodiment of this utility model, the coil spring is made of piano wire.

[0011] As a preferred embodiment of this utility model, the surface of the coil spring is provided with a metal plating layer.

[0012] As a preferred embodiment of this utility model, the wire diameter of the coil spring is 0.3mm-0.7mm, and the coil diameter of the coil spring is 1.5mm-4mm.

[0013] As a preferred embodiment of this utility model, the end of the coil spring connected to the headphone body is provided with a first connecting hook / coil, and the end of the coil spring connected to the assembly is provided with a second connecting hook / coil.

[0014] As a preferred embodiment of this utility model, the top of the earphone body is provided with a first connection port for inserting the end of the coil spring, and the inner cavity of the earphone body is provided with a first connector that cooperates with the first connecting hook / coil near the first connection port; The top of the assembly is provided with a second connection port for inserting the end of the coil spring, and the inner cavity of the assembly is provided with a second connector that cooperates with the second connecting hook / coil near the second connection port.

[0015] Fourthly, this utility model provides an earphone case, including a case body, wherein the case body is provided with a receiving groove for placing a spring clip-on Bluetooth earphone of any of the above-mentioned embodiments.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Spring components are used instead of traditional metal springs. Compared with metal springs, which are prone to fatigue, spring components have higher stability. Their performance is not easily degraded during repeated bending, and they can maintain their original elasticity and stability for a long time, ensuring the continuous reliability of the ear clip function. Due to the high stability of spring components, they are not prone to performance degradation, which not only extends their own service life but also extends the service life of the entire headphone product, reducing the frequency of headphone replacement for users. 2. Unlike existing Bluetooth headsets that achieve elastic deformation by combining shape memory metal and soft rubber, the spring component does not require soft rubber wrapping. This reduces the potential problems of aging and detachment caused by soft rubber, and simplifies the production process and structure, thus reducing costs. 3. By integrating all electrical components into the headphone body, there is no need to use the inner cavity of the spring component for wiring, which eliminates the assembly steps and structural design related to wiring. Combined with the characteristic that the spring component does not need to be wrapped with soft rubber, the overall structure of the headphone is further simplified and the production complexity is reduced. At the same time, it avoids the wiring occupying the internal space of the spring component, and removes the restrictions on the optimization of the spring component structure.

It is also declared that the embodiments described below are only for explaining this utility model and are not intended to limit this utility model.

Example 1

[0022] Please see Figure 1 , Figure 2 This embodiment provides a spring-loaded earbud Bluetooth headset, including an earbud body 1 and an earbud clamping part 2. The earbud body 1 is connected to one end of the earbud clamping part 2, and the other end of the earbud clamping part 2 is provided with an accessory 3. The earbud clamping part 2 is a spring, which is bent and shaped into an arc or U-shape to form an ear clamping space. The accessory 3 and the earbud body 1 are respectively connected to the two ends of the spring, which can provide a reliable fulcrum for the deformation of the spring, so that the two ends of the spring can move closer or further apart through deformation, thereby adapting to the ear size and shape of different users and ensuring wearing comfort and versatility.

[0023] The spring component is a coil spring, preferably made of piano wire. Piano wire possesses high strength, a high elastic limit, and excellent fatigue resistance. Using piano wire as the material for the coil spring ensures that it maintains good elasticity and stability even after repeated deformation, effectively extending its service life. This, in turn, improves the overall reliability and durability of the clip-on Bluetooth headset, reducing headset malfunctions caused by coil spring damage. Of course, in other embodiments, the coil spring can also be made of other metal / plastic materials with high strength, a high elastic limit, and good fatigue resistance; this invention does not impose any limitations on this.

[0024] In this embodiment, a spring component is used instead of a traditional metal spring. Compared to easily fatigued metal springs, the spring component has higher stability. Its performance is less prone to degradation during repeated bending, maintaining its original elasticity and stability for a long time, ensuring the continuous reliability of the ear-clamping function. Due to the high stability of the spring component and its resistance to performance degradation, it not only has a long service life but also extends the overall lifespan of the earphone product, reducing the frequency of earphone replacements. Unlike existing ear-clamping earphones that achieve elastic deformation through a combination of memory metal and soft rubber, this spring component does not require soft rubber wrapping. This reduces potential problems such as aging and detachment of the soft rubber, and simplifies the manufacturing process and structure, lowering costs. By processing and bending the spring component into a U-shape, and connecting its two ends to the earphone body 1 and the mounting accessory 3 respectively, an ear-clamping space is formed to hold the ear, achieving a reliable ear-clamping function and providing a stable wearing experience. Simultaneously, the two ends of the spring component can deform to move closer or further apart to adapt to different ear sizes and shapes, improving wearing comfort and versatility.

[0025] Please see Figure 2 In this embodiment, the headphone body 1 houses electrical components such as a speaker module 11, a circuit board, and a battery 12. By integrating all electrical components into the headphone body 1, wiring is eliminated from the inner cavity of the coil spring, thus removing assembly steps and structural design related to wiring. Furthermore, the fact that the coil spring does not require soft rubber wrapping further simplifies the overall headphone structure and reduces production complexity. Simultaneously, it avoids wiring occupying the internal space of the coil spring, removing limitations on coil spring structure optimization.

[0026] It should be noted that this embodiment does not involve the design of the internal circuitry of the ear-clip Bluetooth headset, therefore, this embodiment will not elaborate on it. In other embodiments, the headset body 1 may also be equipped with microphone modules, charging modules, and other functional modules according to actual needs, to adapt to the functional requirements of different usage scenarios and improve the product's versatility. This utility model does not impose any limitations on this.

[0027] In some embodiments, the wire diameter of the coil spring is 0.3mm-0.7mm, the coil diameter of the coil spring is 1.5mm-4mm, the inner spacing between adjacent coils of the coil spring is 0, the outer spacing between adjacent coils of the coil spring is D, and 0<D<0.25mm.

[0028] The wire diameter range of 0.3mm-0.7mm for the coil spring comprehensively considers the elasticity, strength and space occupation of the coil spring; a thinner wire diameter can increase the flexibility of the coil spring to a certain extent, making it easier to deform, so as to better adapt to the auricle shapes of different users and provide a comfortable wearing experience; at the same time, on the premise of ensuring that the coil spring has sufficient strength, the weight and volume of the earphone will not be increased due to an excessively thick wire diameter, ensuring the portability and compactness of the earphone.

[0029] The coil diameter range of 1.5mm-4mm for the coil spring enables the coil spring to deform uniformly when stressed, distributes stress, improves the stability and durability of the coil spring, and ensures the reliable realization of the ear clamping function; if the coil diameter is too small (less than 1.5mm), local stress concentration may occur when the coil spring deforms, leading to easy damage of the coil spring; while if the coil diameter is too large (greater than 4mm), the elastic performance of the coil spring may be degraded, failing to provide sufficient clamping force.

[0030] By setting the inner spacing between adjacent coils of the coil spring to 0, and the outer spacing between adjacent coils of the coil spring to D where 0<D<0.25mm, it is possible to not only ensure the necessary deformation amount when clamping the auricle, but also avoid the situations that the coil spring is too soft with insufficient clamping force and hair pinching caused by an excessively large outer spacing.

[0031] In some embodiments, the surface of the coil spring 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 environmental pollutants). If the coil spring 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 from weakening in strength, losing elasticity, or even breaking due to rust, 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 impart special metallic colors (such as rose gold or gunmetal gray), enhancing the headphone's technological and metallic feel and meeting users' aesthetic demands. In addition, coil springs may have surface defects such as burrs and scratches during the manufacturing process, while the plating (especially electroplating) can make the surface smoother through filling and polishing, avoiding scratching the skin of the ear when wearing them; at the same time, the smooth surface can also reduce friction and snagging with hair and clothing, improving the ease of use.

[0032] Please see Figure 3 , Figure 4 In some embodiments, the end of the coil spring connected to the headphone body 1 is provided with a first connecting hook / coil 21, and the end of the coil spring connected to the assembly 3 is provided with a second connecting hook / coil 22; the top of the headphone body 1 is provided with a first connecting port for the end of the coil spring to be inserted, and the inner cavity of the headphone body 1 is provided with a first connecting member that cooperates with the first connecting hook / coil 21 near the first connecting port; the top of the assembly 3 is provided with a second connecting port for the end of the coil spring to be inserted, and the inner cavity of the assembly 3 is provided with a second connecting member that cooperates with the second connecting hook / coil 22 near the second connecting port.

[0033] In some embodiments, the first connector is formed by a first screw threadedly connected to the inner cavity of the earphone body 1, and the first connecting hook / ring 21 is fitted onto the screw shank of the first screw; the second connector is formed by a second screw threadedly connected to the inner cavity of the assembly 3, and the second connecting hook / ring 22 is fitted onto the screw shank of the second screw. When installing the coil spring, the operator only needs to insert both ends of the coil spring into the first and second connecting ports respectively, then fit the first connecting hook / ring 21 and the second connecting hook / ring 22 onto the screw shanks of the first and second screws, and finally tighten the first and second screws to complete the installation. No complicated tools or operating procedures are required, greatly improving production efficiency and reducing production costs. At the same time, it is also very convenient for users to perform maintenance operations such as replacing the spring themselves; users can easily disassemble and install the spring without requiring professional knowledge or skills.

[0034] In the above embodiments, by opening a first connection port at the top of the earphone body 1 and a second connection port at the top of the mounting part 3, precise insertion positions are provided for both ends of the coil spring, ensuring that the spring can be accurately positioned during installation. Simultaneously, by connecting the first connector in the inner cavity of the earphone body 1 with the first connecting hook / coil 21, and by connecting the second connector in the inner cavity of the mounting part 3 with the second connecting hook / coil 22, a stable connection can be formed between both ends of the coil spring and the earphone body 1 and the mounting part 3, effectively preventing the coil spring from loosening or falling off during use, and ensuring the stability and reliability of the ear-clamping function. When the earphone is subjected to external forces such as pulling or impact, the connection between the coil spring and the earphone body 1 or mounting part 3 can be prevented from failing due to external forces. Furthermore, by providing connection ports and connectors at the top of the earphone body 1 and the mounting part 3, the top space of the earphone is fully utilized, avoiding complex connection structures in other parts of the earphone, thereby optimizing the internal spatial layout of the earphone.

[0035] Of course, in other embodiments, the first connector may also be a first columnar structure integrally formed with the inner cavity of the earphone body 1, with the first connecting hook / ring 21 fitted onto the first columnar structure; the second connector may be a second columnar connector integrally formed with the inner cavity of the assembly 3, with the second connecting hook / ring 22 fitted onto the second columnar connector. When installing the coil spring, the operator only needs to insert both ends of the coil spring into the first connecting port and the second connecting port respectively, and then fit the first connecting hook / ring 21 and the second connecting hook / ring 22 onto the first columnar structure and the second columnar structure to complete the installation.
