Description

Technical Field

[0001] This utility model relates to the field of electronic products, specifically to a comfortable clip-on earphone. Background Technology

[0002] Existing ear clip headphones typically use rigid plastic clips such as ABS material, relying on an elastic clamping structure for wearing. The ear clip contact surface is a smooth flat surface or a simple arc design, and the clamping force mainly depends on the structural rigidity.

[0003] Existing clip-on earphones have two main drawbacks. First, poor wearing comfort. Current technology uses rigid clamping arms, leading to: 1. Concentrated contact pressure at specific points on the auricle and back of the ear; 2. Pain and discomfort after prolonged wear (continuous pressure ≥1 N / cm²); 3. Hard contact between the concha and the clamping structure. Second, insufficient stability. The existing planar contact design results in: 1. Low coefficient of friction on the auricle skin contact surface (μ≤0.3); 2. Prone to slippage during movement (displacement >2 mm); 3. A drop rate >40% for users with oily skin (actual measured data). Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor wearing comfort and insufficient stability of existing clip-on headphones.

[0005] The technical solution adopted to solve the technical problem proposed by this utility model is as follows: The heat dissipation device of this utility model includes an outer ear clip, an inner ear clip, and an elastic arc-shaped connecting bridge connecting the outer ear clip and the inner ear clip. The inner ear clip is set on the inner side of the lower ear cavity, and the outer ear clip is set on the outer side of the lower ear cavity. The side of the inner ear clip that fits against the ear has an arc-shaped clamping surface that matches the inner side of the lower ear cavity. The side of the outer ear clip that fits against the ear has a supporting surface that matches the outer side of the lower ear cavity. The supporting surface has a flexible anti-slip supporting part, and the anti-slip supporting part is set opposite to the arc-shaped clamping surface.

[0006] The technical solutions that further define this utility model include:

[0007] The external ear clip includes an external ear clip shell, and the internal ear clip includes an internal ear clip shell. The two ends of the arc-shaped connecting bridge are fixedly connected to the external ear clip shell and the internal ear clip shell, respectively. The clamping surface is arc-shaped with a diameter of 10±2mm. The supporting surface is elliptical with the arc-shaped clamping surface positioned in the middle of the elliptical supporting surface.

[0008] The arc-shaped connecting bridge is made of shape memory metal material.

[0009] The anti-slip support part is provided with anti-slip embossed patterns.

[0010] The anti-slip support is one or more elastic rubber strips, which are parallel or perpendicular to the plane of the arc-shaped connecting bridge. The outer ear clip is provided with an elastic rubber strip mounting groove that cooperates with the elastic rubber strip.

[0011] Two elastic rubber strips are provided, and the contact surface length of the elastic rubber strip 41 is ≥10mm. The middle part of the arc-shaped clamping surface is set in the middle of the two elastic rubber strips.

[0012] The elastic strip gradually becomes thinner from the middle to both sides.

[0013] The elastic strip is a silicone strip with a central thickness of 3mm ± 0.5mm and a gradually thinning edge to 1mm.

[0014] The anti-slip support part is the side of the soft rubber sleeve that fits the ear when it is put on the ear clip.

[0015] The soft rubber sleeve is a silicone sleeve with a thickness of 0.5~1.5mm.

[0016] The beneficial effects of this utility model through the above technical solution are as follows: The inner ear clip of the comfortable ear clip-on earphone of this utility model is set corresponding to the inner side of the lower ear canal, and the outer ear clip is set corresponding to the outer side of the lower ear canal. The side of the inner ear clip that fits against the ear has an arc-shaped clamping surface that cooperates with the inner side of the lower ear canal, and the side of the outer ear clip that fits against the ear has a supporting surface that cooperates with the outer side of the lower ear canal. The supporting surface has a flexible anti-slip supporting part, which is set opposite to the arc-shaped clamping surface. In use, the arc-shaped clamping surface and the anti-slip supporting part clamp the inner and outer sides of the lower ear canal respectively. The arc-shaped connecting bridge provides the basic clamping force, and the arc-shaped clamping surface on the inner side and the flexible anti-slip supporting part on the outer side form a dynamic pressure balance.

Detailed Implementation

[0024] The structure of this utility model will be further described below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 6 This utility model discloses a comfortable ear clip-on headphone, comprising an outer ear clip 1, an inner ear clip 2, and an elastic arc-shaped connecting bridge 3 connecting the outer ear clip and the inner ear clip. The outer ear clip 1 includes an outer ear clip shell 11, and the inner ear clip 2 includes an inner ear clip shell 21. The two ends of the arc-shaped connecting bridge 3 are fixedly connected to the outer ear clip shell and the inner ear clip shell, respectively. The arc-shaped connecting bridge 3 is made of shape memory metal. The shape memory metal material can be selected from copper-zinc alloy, copper-aluminum-nickel alloy, etc. The arc-shaped connecting bridge made of shape memory metal can maintain a stable shape and elasticity, providing a stable clamping force for the outer ear clip 1 and the inner ear clip 2. The inner ear clip 2 is positioned on the inner side of the lower ear canal, and the outer ear clip 1 is positioned on the outer side of the lower ear canal. The inner ear clip 2 has an arc-shaped clamping surface 22 on the side that fits against the ear, aligning with the inner side of the lower ear canal. The outer ear clip 1 has a supporting surface 12 on the side that fits against the ear, aligning with the outer side of the lower ear canal. The supporting surface 12 has a flexible, non-slip supporting part 4, which is positioned opposite to the arc-shaped clamping surface 22. The clamping surface 22 is arc-shaped with a diameter of 10±2mm, slightly smaller than the typical size of an adult's lower ear canal. The supporting surface is elliptical, with a spherical arc-shaped part positioned in the center of the elliptical supporting surface, ensuring even force distribution and comfortable wear. When in use, the arc-shaped clamping surface, together with the anti-slip support, clamps the inner and outer sides of the lower ear cavity respectively. The arc-shaped connecting bridge provides the basic clamping force, which, together with the arc-shaped clamping surface on the inner side and the flexible anti-slip support on the outer side, forms a dynamic pressure balance. The flexible anti-slip support not only has a certain cushioning effect to make wearing comfortable, but also has an anti-slip effect to prevent slippage during wearing.

[0026] In this embodiment, the anti-slip support part is provided with anti-slip embossed patterns. The anti-slip embossed patterns increase the friction of the anti-slip support part and prevent slippage when worn.

[0027] In this embodiment, the anti-slip support part 4 consists of two elastic rubber strips 41. The elastic rubber strips are parallel or perpendicular to the plane where the arc-shaped bridge is located. The contact surface 411 of the elastic rubber strips has a length ≥10mm. The ear clip is provided with an elastic rubber strip mounting groove that mates with the elastic rubber strips. The elastic rubber strips are installed in the elastic rubber strip mounting groove. The elastic rubber strips 41 and the elastic rubber strip mounting groove can be connected by interference fit or by adhesive. The middle of the arc-shaped clamping surface corresponds to the middle of the two elastic rubber strips. Thus, the two elastic rubber strips and the arc-shaped clamping surface form a stable triangular clamping structure, preventing slippage during wear. In specific implementations, more than one elastic rubber strip can be provided according to the need for wearing comfort. In this embodiment, the elastic rubber strip gradually thins from the middle to both sides. The elastic rubber strip is a silicone strip with a central thickness of 3mm±0.5mm and gradually thins to 1mm at the edges. The central area of ​​the elastic rubber strip bears most of the pressure, and the thinning edge area disperses the remaining pressure. This gradual structure reduces the pressure in the central area, thereby making wearing more comfortable.

[0028] In this second embodiment, the anti-slip support part 4 is the ear-fitting side 42 of the soft rubber sleeve 5 that fits over the ear clip. The soft rubber sleeve is a silicone sleeve with a thickness of 0.5~1.5mm, and it fits over the ear clip. The soft rubber sleeve is detachable from the ear clip for easy replacement and installation.

[0029] To verify the technical effectiveness of the comfortable ear clip-on headphones proposed in this application, the following experimental or testing methods can be used for verification and comparison with existing technologies:

[0030] (1) Friction verification

[0031] Test method: Use a force gauge to measure the sliding force threshold of the headphones on a simulated skin surface (such as a silicone prosthetic ear model).

[0032] Comparison data:

[0033] Existing technology (without silicone sleeve): sliding force threshold is 0.5-0.8N.

[0034] This patent (with silicone strip / sleeve): Increases the sliding force threshold to 1.2-1.5N.

[0035] Conclusion: The coefficient of friction of the silicone surface is significantly improved, and the anti-slip performance is enhanced by 60%-80%, which verifies the effect of silicone structure on improving wearing stability.

[0036] (2) Comfort verification

[0037] Testing method: Recruit 30 users to conduct blind testing (the headphones were randomly worn before and after the improvement), and record subjective scores (1-5 points, with 5 points being the best).

[0038] Comparison data:

[0039] Existing technology (rigid plastic): Average comfort score 2.1 points

[0040] This patent (silicone contact surface): Average comfort score 4.3 points.

[0041] Conclusion: The softness and elasticity of silicone significantly reduced ear pressure, improving the score by 104%, thus verifying the improvement in comfort.

[0042] (3) Long-term wear test

[0043] Test method: Users are required to wear the earrings continuously for 2 hours, and the number of times they slip off and their feedback on ear discomfort are recorded.

[0044] Comparison data:

[0045] Current technology: average slippage 3 times / hour, 70% of users report ear pain.

[0046] This patent reduces the number of slips to 0-1 times per hour, with only 10% of users reporting a slight feeling of pressure.

[0047] Conclusion: The silicone structure solves both slippage and discomfort problems by dispersing pressure points and increasing friction.

[0048] (4) Comparative experiment (silicone morphology optimization)

[0049] Test variables: Comparing two designs: silicone strip (linear protrusions) and silicone sleeve (full coverage).

[0050] Data conclusions:

[0051] The silicone sleeve offers a more significant increase in friction (+25%), but slightly lower breathability.

[0052] The silicone strip achieves the optimal balance between comfort and friction (overall score 4.5).
