[0002] Clip-on headphones typically consist of two earbuds and a connector that links them. The connector is elastic, allowing the earbuds to clip onto either side of the ear. When wearing the headphones, the user needs to apply force to pull the earbuds apart to fit them on their ears, and the same applies when removing them. Over time, the connector will repeatedly undergo deformation and return to its original shape under stress.

[0003] In related technologies, the connectors of clip-on headphones are prone to breakage and loss of elasticity after repeated deformation, resulting in a short service life. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide an ear clip-on earphone with a longer service life.

The arc-shaped connecting portion connects the first housing and the second housing; the arc-shaped connecting portion includes a wire core, a first elastic portion, and a second elastic portion, the second elastic portion covering the outside of the wire core, and a reset groove formed by a recess on the outer surface of the second elastic portion, the reset groove extending circumferentially along the second elastic portion, and at least a portion of the first elastic portion being disposed within the reset groove.

[0006] In one embodiment, the reset slot is formed at the middle position in the extension direction of the arc-shaped connection.

[0008] In one embodiment, the reset slot includes a first half-slot and a second half-slot, which are arranged symmetrically with respect to the central axis of the arc-shaped connecting portion.

[0009] In one embodiment, the width of the reset slot along the extension direction of the arc-shaped connection is 0.7 to 2.0 mm.

[0010] In one embodiment, the second elastic portion and / or the first elastic portion are integral injection molded structures.

[0011] In one embodiment, the first elastic portion covers the outside of the second elastic portion, and an elastic protrusion is formed on the inner surface of the first elastic portion, with at least a portion of the elastic protrusion located within the reset slot.

[0012] In one embodiment, at least one fixing groove is formed at each of the opposite ends of the second elastic portion extending in the direction of extension, and at least a portion of the elastic protrusion is located within the fixing groove.

[0013] In one embodiment, the wire core includes a wire core body and two fixing rings, which are respectively sleeved on both ends of the wire core body, and the second elastic part is fixed between the two fixing rings.

[0014] In one embodiment, two connecting rings are formed at opposite ends of the second elastic part, and the first and second chambers are formed with connecting grooves that cooperate with the connecting rings; wherein, a limiting groove is formed on the periphery of the connecting ring, and a limiting protrusion that cooperates with the limiting groove is formed in the connecting groove.

[0026] Clip-on headphones typically consist of two earbuds and a connector that links them. The connector is elastic, allowing the earbuds to clip onto either side of the ear. When wearing the headphones, the user needs to apply force to pull the earbuds apart to fit them on their ears, and the same applies when removing them. Over time, the connector will repeatedly undergo deformation and return to its original shape under stress.

[0027] In related technologies, the connectors of clip-on headphones are prone to breakage and loss of elasticity after repeated deformation, resulting in a short service life.

[0028] In view of this, refer to Figure 1This application aims to provide an ear-clamping earphone 100, including a first housing 110, a second housing 120, and an arc-shaped connecting portion 130. The arc-shaped connecting portion 130 connects the first housing 110 and the second housing 120; the arc-shaped connecting portion 130 includes a wire core 131, a first elastic portion 132, and a second elastic portion 133. The second elastic portion 133 covers the outside of the wire core 131, and a reset groove 1331 is recessed on the outer surface of the second elastic portion 133. The reset groove 1331 extends circumferentially, and at least a portion of the first elastic portion 132 is disposed within the reset groove 1331.

[0029] To facilitate understanding, the wearing process of the clip-on earphone 100 is explained below: First, in its natural state, the first housing 110, the second housing 120, and the arc-shaped connecting part 130 of the clip-on earphone 100 together form a clamping space 100a. At this time, the first housing 110 and the second housing 120 are relatively close, and their distance is considered as the first distance, which is adapted to the thickness of the ear helix. When the user needs to wear the clip-on earphone 100, they need to increase the distance between the first housing 110 and the second housing 120. At this time, the user needs to apply external force to the arc-shaped connecting part 130. Understandably, this external force can be applied to the first housing 110 and the second housing 120, or it can be applied directly to the arc-shaped connecting part 130. At this time, the first distance will be increased, which is considered as the second distance. Naturally, the second distance will be greater than the thickness of the user's ear helix, and sufficient for the ear helix to pass through. Afterwards, once the user's earlobe enters the clamping space 100a, the user removes the external force. At this point, the first chamber 110, the second chamber 120, and the arc-shaped connecting part 130 will return to their natural state, and the second gap will be pulled back to the first gap, thus allowing the ear-clamping headphone 100 to clamp the user's earlobe, achieving wearing. The specific structural form of the first chamber 110 and the second chamber 120 is not limited; their shapes and / or sizes can be the same or different.

[0030] At least one of the first chamber 110 and the second chamber 120 is provided with a sound-emitting structure to realize the sound-emitting function. As an example, one of the first chamber 110 and the second chamber 120 is provided with a sound-emitting structure (e.g., the one closer to the user's external auditory canal in actual use), and the other (e.g., the one farther away from the user's external auditory canal in actual use) is provided with one or more of a battery, a communication device, a control panel, and control buttons.

[0031] The wire core 131 is used to electrically connect the first housing 110 and the second housing 120. The second elastic portion 133 covers the outside of the wire core 131. As an example, the second elastic portion 133 has a U-shaped outer contour extending around the clamping space 100a.

[0032] Reference Figure 1A reset groove 1331 is formed on the outer surface of the second elastic portion 133. The reset groove 1331 extends circumferentially along the second elastic portion 133, and at least a portion of the first elastic portion 132 is located within the reset groove 1331.

[0033] In this embodiment, the first elastic portion 132 can be entirely located within the reset slot 1331. For example, the first elastic portion 132 can be formed into a block structure, ring structure, semi-ring structure, etc., corresponding to the shape of the reset slot 1331, and is disposed within the reset slot 1331 by means of bonding, secondary injection molding, etc. Alternatively, in combination with... Figure 2 and Figure 3 The first elastic portion 132 may also be located only in the reset slot 1331. For example, the first elastic portion 132 may cover or surround the outside of the second elastic portion 133. The first elastic portion 132 may form an elastic protrusion 132a, which is located in the reset slot 1331.

[0034] Taking the elastic protrusion 132a as an example, the outer surface of the elastic protrusion 132a establishes a fitting relationship with the inner surface of the reset slot 1331. When the first gap is pulled to the second gap, the end of the reset slot 1331 near the clamping space 100a is stretched, and the elastic protrusion 132a at this point is also stretched; at the same time, the end of the reset slot 1331 away from the clamping space 100a is compressed, and the elastic protrusion 132a at this point is also compressed. During the process of returning from the second gap to the first gap, the gap of the reset slot 1331 near the clamping space 100a will be restored by the recovery trend of the elastic protrusion 132a at this point, and the same applies to the gap of the reset slot 1331 away from the clamping space 100a.

[0035] In this embodiment, by setting the reset slot 1331, the arc-shaped connecting part 130 can buffer some of the bending stress, thereby reducing the probability of internal tearing of the arc-shaped connecting part 130 during repeated deformation and bending, improving the strength and toughness of the arc-shaped connecting part 130, and thus improving the service life of the ear clip earphone 100.

[0036] Furthermore, during the deformation of the arc-shaped connecting portion 130, a portion of elastic potential energy is stored in the first elastic portion 132, and this elastic potential energy is released during the recovery deformation process, which helps the arc-shaped connecting portion 130 return to its natural state, thereby increasing the deformation recovery capability of the arc-shaped connecting portion 130.

[0037] In some embodiments, refer to Figure 1 and Figure 3 The first elastic portion 132 covers the outer side of the second elastic portion 133, and an elastic protrusion 132a is formed on the inner surface of the first elastic portion 132. At least a portion of the elastic protrusion 132a is located in the reset slot 1331.

[0038] Specifically, the first elastic part 132 forms a complete protective layer on the outside of the second elastic part 133, and the elastic protrusion 132a inside the first elastic part 132 fits against the inner side of the reset slot 1331.

[0039] Thus, the second elastic part 133 and the wire core 131 will not come into contact with the outside world under the cover of the first elastic part 132. On the one hand, it can better protect the second elastic part 133 and the wire core 131. On the other hand, the elastic protrusion 132a fits into the reset slot 1331 and plays a certain limiting role, reducing the possibility of the first elastic part 132 moving relative to the second elastic part 133.

[0040] In some embodiments, the hardness of the second elastic portion 133 is higher than the hardness of the first elastic portion 132.

[0041] In the relevant technical means, the hardness distribution of the arc-shaped connecting part 130 is relatively uniform. This means that when the hardness of the arc-shaped connecting part 130 is designed to be high, the ear clip earphone 100 will generate a large clamping force, which may cause fatigue and damage to the muscle group at the helix of the ear when worn for a long time. On the other hand, when the hardness of the arc-shaped connecting part 130 is designed to be low, it is not possible to maintain sufficient clamping force to maintain the stability of wearing the earphone.

[0042] Thus, the first elastic part 132, with its lower hardness, makes flexible contact with the auricle at its periphery, facilitating the contact between the ear-clamping earphone 100 and the skin, thereby improving the wearing comfort of the ear-clamping earphone 100. The second elastic part 133, with its higher hardness, shapes the arc-shaped connecting part 130, reducing the risk of the two ends of the arc-shaped connecting part 130 springing back outward, ensuring that the ear-clamping earphone 100 is reliably clamped to the ear. On the other hand, the second elastic part 133 is disposed within the first elastic part 132, and the lower hardness of the first elastic part 132 can cushion the second elastic part 133, reducing the risk of the second elastic part 133 undergoing abrupt shape changes due to accidental contact or drop. The elastic force of the elastic element is related to the usage time. In this embodiment, the first elastic part 132 and the second elastic part 133 work together to reduce the risk of the arc-shaped connecting part, made of a single elastic element, becoming unbalanced and detaching under long-term wear, thereby improving the reliability of wearing.

[0043] In some embodiments, the Shore hardness range of the first elastic portion 132 is 70A to 90A. The Shore hardness range of the second elastic portion 133 is 80A to 100A. Furthermore, the hardness of the second elastic portion 133 is higher than that of the first elastic portion 132. It should be explained that Shore hardness refers to the degree measured using a Shore hardness tester; it is an absolute hardness value. A higher degree indicates a harder material, and a lower degree indicates a softer material. In this embodiment, the first elastic portion 132 can be understood as a kind of "soft rubber," which is easier to process and bend, making the outer contour surface of the arc-shaped connecting portion 130 smoother and further improving user wearing comfort. The second elastic portion 133 can be understood as a kind of "skeleton," with greater elasticity. On the one hand, it can deform under external force; on the other hand, it also has the ability to quickly return to its natural state after the external force is removed.

[0044] In some embodiments, refer to Figure 1 The reset slot 1331 is formed at the middle position in the extending direction of the arc-shaped connecting portion 130.

[0045] Understandably, the middle position of the arc-shaped connecting part 130 in the extending direction is the position where the stress on the ear clip earphone 100 is most concentrated due to bending deformation. Therefore, the resistance to plastic deformation at this position should be stronger.

[0046] Thus, by forming the reset slot 1331 at the middle position in the extending direction of the arc-shaped connecting portion 130, the ear clip earphone 100's resistance to plastic deformation is further enhanced, and the elastic life of the ear clip earphone 100 is improved.

[0047] In some embodiments, refer to Figure 1 There are multiple reset slots 1331, which are distributed at intervals along the extension direction of the arc-shaped connecting part 130.

[0048] Specifically, refer to Figure 2 A rib-shaped reinforcing rib 1333 is formed between multiple spaced reset slots 1331. The width of the rib-shaped reinforcing rib 1333 along the extension direction of the arc-shaped connecting portion 130 is approximately the same as the width of the reset slot 1331 along the extension direction of the arc-shaped connecting portion 130.

[0049] Thus, on the one hand, the multiple reset slots 1331 are evenly spaced on the arc-shaped connecting portion 130, which makes the bending stress received by the arc-shaped connecting portion 130 more evenly distributed and reduces the possibility of stress concentration. On the other hand, the provision of multiple reset slots 1331 also means that the first elastic portion 132 can be provided with more elastic protrusions 132a to cooperate with the reset slots 1331, thereby achieving better deformation recovery of the arc-shaped connecting portion 130.

[0050] In some embodiments, refer to Figure 1 and Figure 3 The reset slot 1331 includes a first half-slot 1331a and a second half-slot 1331b, which are arranged symmetrically with respect to the central axis of the arc-shaped connecting part 130.

[0051] As an example, refer to Figure 3 and Figure 4 The arc-shaped connecting portion 130 can be divided into an upper part and a lower part by taking the central axis of the arc-shaped connecting portion 130 as the boundary. The first half-groove 1331a and the second half-groove 1331b are symmetrically arranged in the upper and lower parts and correspond one-to-one. A ridge 1334 is formed between each first half-groove 1331a and its corresponding second half-groove 1331b. Naturally, a portion of the ridge 1334 is formed on the side closer to the clamping space 100a, and a portion of the ridge 1334 is formed on the side away from the clamping space 100a.

[0052] Thus, simultaneously providing the first half-groove 1331a and the second half-groove 1331b will provide a better deformation recovery effect for the arc-shaped connecting part 130. In addition, when the ear-clamping earphone 100 deforms from its natural state, the spine 1334 on the side closer to the clamping space 100a will be stretched, and the spine 1334 on the side farther from the clamping space 100a will be compressed. This will also generate a certain amount of elastic potential energy, so that the spine 1334 can also provide additional elastic force during the process of the ear-clamping earphone 100 returning to its natural state.

[0053] In some embodiments, refer to Figure 1 The width distribution of the reset slot 1331 along its circumferential extension direction is not uniform. In its natural state, the width of the reset slot 1331 is smaller on the side closer to the clamping space 100a and larger on the side farther from the clamping space 100a. Correspondingly, the elastic protrusion 132a within the reset slot 1331 is smaller on the side closer to the clamping space 100a and larger on the side farther from the clamping space 100a.

[0054] Thus, when the arc-shaped connecting part 130 deforms, the elastic protrusion 132a on the wider side will be compressed, storing greater elastic potential energy, and thus achieving better deformation recovery.

[0055] In one embodiment, the width of the reset slot 1331 along the extension direction of the arc-shaped connecting portion 130 is 0.7 to 2.0 mm. Further, the width of the rib-shaped reinforcing rib 1333 along the extension direction of the arc-shaped connecting portion 130 is also 0.7 to 2.0 mm.

[0056] In some embodiments, the second elastic portion 133 and / or the first elastic portion 132 are integral injection molded structures.

[0057] Thus, the inner contour surface of the first elastic part 132 of the one-piece injection molded structure can better fit the outer side of the wire core 131, and the inner contour surface of the second elastic part 133 of the one-piece injection molded structure can similarly better fit the outer contour of the first elastic part 132. Better fit means better deformation recovery capability. Moreover, since both the first elastic part 132 and the second elastic part 133 are irregularly shaped parts, the one-piece injection molding method is simpler, more efficient, and less costly.

[0058] Reference Figure 2 In an embodiment where the first elastic portion 132 covers the outer side of the second elastic portion 133, at least one fixing groove 1332 is formed at each of the opposite ends of the second elastic portion 133 in the extending direction, and at least a portion of the elastic protrusion 132a is located in the fixing groove 1332.

[0059] Specifically, the fixing slot 1332 is similar in structure to the reset slot 1331, and is a slot structure extending circumferentially formed by recessing into the outer surface of the second elastic portion 133. Exemplarily, in one embodiment, the fixing slot 1332 includes two semi-grooves arranged symmetrically with respect to the central axis of the arc-shaped connecting portion 130; in another embodiment, the fixing slot 1332 is a closed-loop groove circumferentially surrounding the second elastic portion 133.

[0060] Understandably, since the first elastic part 132 has a certain degree of elasticity, during long-term use of the ear-clamping earphone 100, the two ends of the first elastic part 132 will inevitably tend to shrink towards the middle, which will cause the two ends of the second elastic part 133 to be exposed. The purpose of providing the fixing slot 1332 is that the elastic protrusion 132a located in the fixing slot 1332 will cooperate with the fixing slot 1332 to play a limiting role and reduce the tendency of the first elastic part 132 to shrink towards the middle.

[0061] In some embodiments, refer to Figure 2 The wire core 131 includes a wire core body 1311 and a fixing ring 1312. There are two fixing rings 1312, which are respectively sleeved on both ends of the wire core body 1311, and the second elastic part 133 is fixed between the two fixing rings 1312.

[0062] Specifically, the length of the core body 1311 will be greater than the length of the second elastic part 133 along its extension direction. After the second elastic part 133 covers the outside of the core body 1311, two fixing rings 1312 are then snapped onto both ends of the core body 1311.

[0063] In this way, the retaining ring 1312 can play a limiting role, controlling the second elastic part 133 between the two retaining rings 1312, reducing the possibility of the second elastic part 133 sliding along the core body 1311.

[0064] In some embodiments, refer to Figure 1 and Figure 2 Connecting rings 1335 are formed at opposite ends of the second elastic portion 133, and connecting grooves that mate with the connecting rings 1335 are formed on the first compartment 110 and the second compartment 120. This not only fixes the first compartment 110 and the second compartment 120 on the second elastic portion 133, but also further limits the position of the second elastic portion 133.

[0065] Specifically, refer to Figure 4 A limiting groove 1335a is formed on the periphery of the connecting ring 1335, and a limiting protrusion that mates with the limiting groove is formed in the connecting groove. In this way, the limiting groove 1335a can reduce the possibility of the first compartment 110 or the second compartment 120 rotating around the connecting ring 1335.

[0066] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
