Description

Technical Field

[0001] This utility model belongs to the field of Bluetooth headset technology, and more specifically, it relates to an ear clip-on Bluetooth headset. Background Technology

[0002] In existing clip-on Bluetooth headset structures, the connection between the flexible ear clip and the speaker shell is a weak point in terms of sealing. Traditional connection methods often rely on adhesive bonding for adhesion and sealing. However, this process has significant drawbacks: First, the uniformity and integrity of the adhesive application are difficult to control precisely, easily leading to tiny gaps or discontinuities; second, with prolonged use or under external pulling force, the adhesive layer may age, crack, or peel off. These factors combined make this connection highly susceptible to water ingress and air leakage. Water ingress directly threatens the safety of the electronic components inside the speaker shell, shortening the product's lifespan; while air leakage severely compromises the acoustic seal of the speaker's rear cavity, causing distortion, attenuation, muffled sound, or abnormal noise in the audio signal (especially low frequencies), significantly degrading sound quality. Furthermore, if poor adhesive bonding leads to seal failure or requires repair, forced disassembly often damages the ear clip, shell, or other precision components due to excessive adhesive force, resulting in irreversible "disassembly damage," increasing after-sales costs and wasting resources. Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide an ear clip-on Bluetooth headset, in order to achieve a more practical value. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an ear clip-on Bluetooth headset, which is achieved by the following specific technical means:

[0004] An ear clip-on Bluetooth headset includes an ear shell, a speaker shell, and a flexible ear clip. The two ends of the flexible ear clip are connected to the ear shell and the speaker shell, respectively. Each end of the flexible ear clip is provided with a connecting foot one and a connecting foot two. The top of the ear shell has a connecting hole one, into which the connecting foot one is inserted and forms an interference fit. A silicone sealing ring is fitted onto the outer side of the connecting foot two. The top of the speaker shell has a connecting hole two, into which the silicone sealing ring is installed and forms an interference fit.

[0005] Furthermore, the silicone sealing ring has a central mounting hole for connecting to the second connecting leg, and the mounting hole and the second connecting leg are interference fit.

[0006] Furthermore, an anti-detachment flange is provided on the outer side of the bottom end of the second connecting foot, and a sealing flange is provided on the outer side of the bottom end of the silicone sealing ring. The sealing flange is located on the top side of the anti-detachment flange; the dimensions of the anti-detachment flange and the sealing flange are both larger than the dimensions of the second connecting hole.

[0007] Furthermore, two sets of limiting blocks are symmetrically arranged at the inner bottom end of the first connecting hole, and a pair of anti-disengagement blocks that can engage with the limiting blocks are arranged at the bottom end of the first connecting foot.

[0008] Furthermore, the flexible ear clip is made of soft silicone, while the connecting feet at both ends are made of hard plastic.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This invention fundamentally solves the problem of weak sealing at the connection between the flexible ear clip and the speaker shell by using a physical interference fit structure instead of traditional adhesive bonding. This ensures a uniform and complete seal at the connection point, effectively eliminating tiny gaps caused by uneven adhesive application, aging and cracking, or external pulling. This significantly improves waterproof and airtight performance, eliminates the risk of water damage to internal electronic components, and ensures the acoustic airtightness of the speaker's rear cavity, avoiding low-frequency distortion, attenuation, muffled sound, or abnormal noise. This greatly optimizes and stabilizes the product's sound quality performance. Attached Figure Description

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides an ear clip-on Bluetooth headset, including an ear shell 1, a speaker shell 2, and a flexible ear clip 3. The two ends of the flexible ear clip 3 are connected to the ear shell 1 and the speaker shell 2, respectively. The two ends of the flexible ear clip 3 are respectively provided with a first connecting foot 301 and a second connecting foot 302. The top of the ear shell 1 is provided with a first connecting hole 101, and the first connecting foot 301 is inserted into the first connecting hole 101, forming an interference fit. A silicone sealing ring 4 is fitted onto the outer side of the second connecting foot 302. The top of the speaker shell 2 is provided with a second connecting hole 201, and the silicone sealing ring... 4. It is installed in the second connecting hole 201 and forms an interference fit with it; through the interference fit between the first connecting foot 301 and the first connecting hole 101, and the interference fit between the second connecting foot 302 and the second connecting hole 201 through the silicone sealing ring 4, the traditional glue bonding sealing method is completely replaced. This physical interference fit structure fundamentally solves the gap problem caused by uneven glue application and easy aging and cracking, significantly improves the initial sealing integrity of the connection part, and effectively prevents moisture and gas from entering or escaping from these key connection points, laying a solid foundation for waterproof and acoustic airtightness.

[0025] The silicone sealing ring 4 has a central mounting hole for connecting to the second connecting leg 302, and the mounting hole and the second connecting leg 302 are in an interference fit. The interference fit between the central mounting hole of the silicone sealing ring 4 and the second connecting leg 302 ensures that the silicone sealing ring can tightly wrap around the second connecting leg 302, eliminating the risk that moisture or air may seep into the inside of the speaker shell 2 along the surface of the second connecting leg 302, forming the first sealing barrier. At the same time, this tight fit firmly fixes the silicone sealing ring 4 to the second connecting leg 302, preventing it from shifting or falling off during assembly or use, and ensuring the durability of the seal.

[0026] The bottom outer side of the connecting foot 302 is provided with an anti-detachment flange, and the bottom outer side of the silicone sealing ring 4 is provided with a sealing flange. The sealing flange is located on the top side of the anti-detachment flange. The dimensions of the anti-detachment flange and the sealing flange are both larger than the dimensions of the connecting hole 201. After assembly, the anti-detachment flange is locked below the connecting hole 201, providing a stable mechanical locking force, effectively preventing the connecting foot 302 from accidentally coming out of the speaker shell 2, enhancing the tensile strength of the overall structure, and forming a tight fit with the sealing flange, which can further improve the sealing performance.

[0027] Among them, two sets of limiting blocks 102 are symmetrically arranged at the inner bottom end of the connecting hole 101, and a pair of anti-disengagement blocks 303 that can engage with the limiting blocks 102 are arranged at the bottom end of the connecting foot 301. The interlocking structure of the limiting blocks 102 and the anti-disengagement blocks 303 provides additional mechanical locking for the connection between the connecting foot 301 and the ear shell 1, preventing the connecting foot 301 from axially loosening in the connecting hole 101, and ensuring the firmness and stability of the connection between the flexible ear clip 3 and the ear shell 1.

[0028] The flexible ear clip 3 is made of soft silicone, while the connecting pins 301 and 302 at both ends are made of hard plastic. All three components (flexible ear clip 3, connecting pin 301, and connecting pin 302) have interconnected cable routing channels. The soft silicone of the flexible ear clip 3 ensures comfort and a snug fit, while the hard plastic connecting pins 301 and 302 provide the necessary structural strength and rigidity, ensuring reliable interference fit and locking mechanisms. The interconnected cable routing channels provide a neat and protected hidden path for the internal cables, avoiding wear and tear risks caused by exposed cables and improving the neatness and long-term durability of the product's internal structure.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
