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 headset case. Background Technology

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

[0003] Among them, clip-on headphones that achieve elastic deformation by combining shape memory metal and soft rubber are exemplified by Chinese utility model patent CN119545232A, which discloses a clip-on headphone comprising: 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 the two earpieces. The metal spring has two states: static straight and static bent. The metal spring has at least two trigger points. Pressing one of the trigger points can trigger the metal spring to deform to the static straight state, thereby causing the two earpieces to move towards each other to form an ear-clamping position; pressing the other trigger point can trigger the metal spring to deform to the static bent state, thereby causing the two earpieces to move in opposite directions, thus allowing the clip-on headphones to be removed from the ears.

[0004] While the aforementioned clip-on headphones 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 its original elasticity and stability, thus resulting in a shorter lifespan for the entire clip-on headphone. After prolonged use, due to the fatigue and performance degradation of the metal springs, the headphones may loosen, not only reducing their secure fit on the ears and potentially causing them to slip off, but also decreasing user comfort and ultimately affecting the user's overall experience and evaluation of the clip-on headphone product. Utility Model Content

[0005] In order to overcome the problems of easy fatigue and short service life of the metal spring in the existing clip-on earphones that achieve elastic deformation through metal springs and soft rubber, 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:

[0007] On one hand, this utility model provides a spring-loaded ear-clamping Bluetooth earphone, including a cavity part, an earphone body part, and a metal coil spring connected between the cavity part and the earphone body part. The metal coil spring is bent and shaped into an ergonomic arc or U shape. The two ends of the metal coil spring are respectively connected to the cavity part and the earphone body part, so that an ear clamping space for clamping the auricle is formed between the cavity part and the earphone body part. A wiring channel connecting the inner cavity of the cavity part and the inner cavity of the earphone body part is formed inside the metal coil spring.

[0008] As a preferred embodiment of this utility model, the two ends of the metal coil spring are provided with snap-fit ​​parts, and the cavity part and the earphone body part are provided with snap-fit ​​grooves or recesses that cooperate with the snap-fit ​​parts.

[0009] As a preferred embodiment of this utility model, the cavity portion and the earphone body portion are respectively provided with connecting portions that cooperate with the two ends of the metal coil spring.

[0010] As a preferred embodiment of this utility model, the wire diameter of the metal coil spring is between 0.3 mm and 0.7 mm.

[0011] As a preferred embodiment of this utility model, the coil diameter of the metal coil spring is between 1.5 mm and 4 mm.

[0012] In a preferred embodiment of this invention, the outer spacing between the coils of the metal coil spring is D. .

[0013] As a preferred embodiment of this utility model, the metal coil spring is made of piano wire.

[0014] As a preferred embodiment of this utility model, the surface of the metal coil spring is provided with a metal plating layer.

[0015] As a preferred embodiment of this utility model, a circuit board, a battery module and a charging module are provided inside the cavity, a charging hole is provided on the cavity, the charging module and the charging hole are correspondingly provided, and the circuit board and the charging module are both electrically connected to the battery module;

[0017] On the other hand, this utility model provides an earphone case, including a case body, wherein a receiving groove is provided in the case body for placing the spring-loaded clip-on Bluetooth earphone described in any of the above embodiments.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Metal coil springs are used instead of traditional metal springs. Compared with easily fatigued metal springs, metal coil springs 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 their high stability and the fact that they are not prone to performance degradation, metal coil springs have a long service life, which also extends the service life of the entire headphone product and reduces the frequency with which users need to replace the headphones due to component damage.

[0020] 2. Unlike existing clip-on headphones that achieve elastic deformation by combining shape memory metal and soft rubber, this metal coil spring does not require soft rubber wrapping. On the one hand, it reduces the problems of aging and falling off that may be caused by soft rubber, and on the other hand, it simplifies the production process and structure, and reduces costs.

[0021] 3. The internal wiring design of the metal coil spring not only improves the utilization of the internal space of the headphones, but also showcases a unique metallic technological feel, bringing users a novel visual experience; at the same time, it also increases the playability of the product.

[0033] Please see Figures 1 to 4This utility model provides a spring-loaded ear-clamping Bluetooth headset, including a cavity portion 1, an earphone body portion 2, and a metal coil spring 3 connected between the cavity portion 1 and the earphone body portion 2. The metal coil spring 3 is bent and shaped into an ergonomic U-shape. Both ends of the metal coil spring 3 are connected to the cavity portion 1 and the earphone body portion 2 respectively, forming an ear-clamping space between the cavity portion 1 and the earphone body portion 2 for clamping the ear. The size of the ear-clamping space is adjusted by bending the metal coil spring 3 to change the relative position between the cavity portion 1 and the earphone body portion 2, thereby clamping the ear. The interior of the metal coil spring 3 forms a wiring channel connecting the inner cavity of the cavity portion 1 and the inner cavity of the earphone body portion 2.

[0034] This invention uses a metal coil spring 3 instead of a traditional metal spring. Compared to easily fatigued metal springs, the metal coil spring 3 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 its high stability and low performance degradation, the metal coil spring 3 has a long service life, extending the overall lifespan of the earphone and reducing the frequency of earphone replacements due to component damage. Unlike existing ear-clamping earphones that achieve elastic deformation through a combination of memory metal and soft rubber, this metal coil spring 3 does not require soft rubber wrapping. This reduces potential problems such as aging and detachment of the soft rubber, simplifies the manufacturing process and structure, and lowers costs. Furthermore, the internal wiring design of the metal coil spring 3 not only improves the utilization of the earphone's internal space but also showcases a unique metallic technological feel, providing users with a novel visual experience and increasing the product's playability.

[0035] In one embodiment, the metal coil spring 3 has snap-fit ​​portions at both ends, and the cavity portion 1 and the earphone body portion 2 have slots or recesses that mate with the snap-fit ​​portions. The snap-fit ​​portions engaging with the slots or recesses provide a certain connection strength, maintaining a relatively stable connection between the metal coil spring 3 and the cavity portion 1 and the earphone body portion 2. Simultaneously, the snap-fit ​​method simplifies and speeds up the installation process; simply aligning the snap-fit ​​portion with the slot or recess and inserting it completes the connection without complex tools or procedures, improving production and assembly efficiency and reducing labor costs. Furthermore, when the metal coil spring 3 is damaged or needs replacement, the snap-fit ​​structure simplifies disassembly. By carefully removing the snap-fit ​​portion from the slot or recess, the metal coil spring 3 can be separated from the cavity portion 1 and the earphone body portion 2, facilitating individual repair or replacement of the metal coil spring 3, reducing product maintenance costs, and improving product lifespan and sustainability. It should be noted that this embodiment does not limit the specific structure of the snap-fit ​​part, the snap-fit ​​slot, or the groove; it is sufficient to achieve the snap-fit ​​function of both.

[0036] In one embodiment, the cavity portion 1 and the earphone body portion 2 are respectively provided with connecting portions that mate with both ends of the metal coil spring 3. The metal coil spring 3 is tightly connected to the cavity portion 1 and the earphone body portion 2 through the connecting portions, forming an organic whole. By specifically providing connecting portions that mate with both ends of the metal coil spring 3, precise design can be made according to the specific shape, size, and mechanical properties of the metal coil spring 3, achieving a tight fit and optimal force transmission effect between the metal coil spring 3 and the cavity portion 1 and the earphone body portion 2. It should be noted that this embodiment does not limit the specific structure of the connecting portions; it only needs to achieve the function of connecting with both ends of the metal coil spring 3.

[0037] In one embodiment, the wire diameter of the metal coil spring 3 ranges from 0.3mm to 0.7mm, and the coil diameter ranges from 1.5mm to 4mm. A suitable wire diameter (0.3mm to 0.7mm) for the metal coil spring 3 can reduce the weight of the headphones while ensuring the necessary clamping force, reducing pressure on the ear and improving wearing comfort. A suitable coil diameter (1.5mm to 4mm) helps the metal coil spring 3 better conform to the shape of the ear, resulting in a more even distribution of clamping force and avoiding discomfort caused by excessive local pressure.

[0038] In one embodiment, the inner spacing between the coils of the metal coil spring 3 is 0, and the outer spacing between the coils of the metal coil spring 3 is D. The parameter design of the metal coil spring 3 described above can ensure the necessary deformation when clamping the auricle, while avoiding the situation where the spring is too soft, the clamping force is insufficient, or the hair is caught due to excessively large outer spacing.

[0039] In one embodiment, the metal coil spring 3 is made of piano wire. Piano wire has high strength, high elastic limit, and good fatigue resistance. Using piano wire as the material for the metal coil spring 3 ensures that the spring maintains good elasticity and stability during repeated deformation, effectively extending the spring's service life. This, in turn, improves the overall reliability and durability of the clip-on Bluetooth headset and reduces headset malfunctions caused by spring damage.

[0040] Of course, in other embodiments, the material of the metal coil spring 3 may also be stainless steel, titanium alloy, shape memory alloy, etc. This utility model does not limit this, and those skilled in the art can freely choose according to their own needs.

[0041] In one embodiment, the surface of the metal coil spring 3 is provided with a metal plating layer, which can play a role in preventing rust and corrosion, increasing the metallic feel, and increasing surface smoothness. As an everyday wearable device, 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 metal coil spring 3 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 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 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 metal coil spring 3 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.

[0042] Please see Figure 2 , Figure 3 In one embodiment, the cavity 1 is provided with a circuit board 11, a battery module 12 and a charging module 13, and a charging hole 14 is provided on the cavity 1. The charging module 13 and the charging hole 14 are respectively provided. The circuit board 11 and the charging module 13 are both electrically connected to the battery module 12. The earphone body 2 is provided with a speaker unit 21, and the speaker unit 21 and the circuit board 11 are electrically connected through a flexible circuit.

[0043] Specifically, when the clip-on Bluetooth earbuds are placed in the earphone case, the charging port 14 on the earbuds corresponds to the metal contacts inside the earphone case. The metal contacts pass through the charging port 14 and are electrically connected to the charging module 13. The charging module 13 receives electrical energy from the power source inside the earphone case and converts it into a form of electrical energy (usually direct current) suitable for charging the battery module 12 of the clip-on Bluetooth earbuds through its internal circuitry, thereby charging the earbuds. It should be noted that this embodiment does not involve the design of the internal circuitry of the clip-on Bluetooth earbuds; therefore, this embodiment will not elaborate on it. Example 2

[0044] Please see Figure 5 This utility model provides a spring-loaded ear-clamping Bluetooth headset, including a cavity portion 1, an earphone body portion 2, and a metal coil spring 3 connected between the cavity portion 1 and the earphone body portion 2. The metal coil spring 3 is bent and shaped into an ergonomic arc. Both ends of the metal coil spring 3 are connected to the cavity portion 1 and the earphone body portion 2 respectively, forming an ear-clamping space between the cavity portion 1 and the earphone body portion 2 for clamping the ear. The size of the ear-clamping space is adjusted by bending the metal coil spring 3 to change the relative position between the cavity portion 1 and the earphone body portion 2, thereby clamping the ear. The interior of the metal coil spring 3 forms a wiring channel connecting the inner cavity of the cavity portion 1 and the inner cavity of the earphone body portion 2.

[0045] This invention uses a metal coil spring 3 instead of a traditional metal spring. Compared to easily fatigued metal springs, the metal coil spring 3 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.
