Description

Technical Field

[0001] The utility model relates to the field of earphones, in particular to an ear-hook hearing-aid earphone with an anti-slip function. Background Art

[0002] Hearing-assistive headphones are enhanced earphones suitable for people with mild hearing loss. They can perform some of the functions of hearing aids, such as compensating for segmented sound compression. They are primarily designed for people with mild hearing loss caused by long-term use of headphones and listening to music at high volume, or for those experiencing hearing loss with aging. While hearing-assistive headphones can provide some hearing assistance, they differ significantly from hearing aids in terms of function and technology. Hearing aids can be carefully and accurately adjusted based on the individual's specific hearing condition and frequency, meeting various listening needs in different scenarios.

[0003] Existing ear-hook hearing aids are usually hung on the ear through a curved tube extending from the earphone and the motherboard. The curved tube is usually made of plastic. When the skin in the ear area sweats, the friction between the connecting wire and the skin will decrease, causing the earphone to easily slip off the ear and cause damage. In addition, due to the different sizes and shapes of ears, ear-hook hearing aids are not suitable for some people. Utility Model Content

[0004] The purpose of the utility model is to provide an ear-hook hearing aid headset with an anti-slip function, which has the characteristic of being stable when worn.

[0031] The following combination Figures 1 to 6 , describing an ear-hook hearing aid headset with anti-slip function according to an embodiment of the present invention.

[0032] An ear-hook hearing aid headset with anti-slip function includes a host 1 and a receiver 7. The host 1 is spliced ​​by a bottom shell 101 and an outer shell 102. A support plate 2 is provided on one side of the host 1, and a function key 3 is embedded in the support plate 2 to improve the installation stability of the function key 3. The two side edges of the support plate 2 are respectively limited to the bottom shell 101 and the outer shell 102. The top of the host 1 is movably connected to an extension tube 6 through an extended curved tube 4. The curved tube 4 and the extension tube 6 are movably connected, so that the position of the receiver 7 can be adjusted, and the headset can be flexibly The extension tube 6 is adapted to accommodate different ear shapes and sizes. The end away from the curved tube 4 is fixedly connected to the receiver 7. A silicone sleeve 5 is partially covered on the exterior of the curved tube 4 to enhance wearing comfort. The receiver 7 is threadedly connected to a concha block 8, which comprises a connecting ring 802 and a fin-shaped retaining plate 803. The fin-shaped retaining plate 803 is attached to the outer wall of the connecting ring 802. The inner wall of the connecting ring 802 is provided with an internal thread 801, which the receiver 7 engages with via the external external thread 701. The design of the connecting ring 802 allows the concha block 8 to fit more closely against the side surface of the receiver 7.

[0033] Specifically, the concha piece 8 is tightly coupled to the receiver 7 via a threaded connection, allowing the earphones to fit more closely against the concha inside the user's ear. This improves wearing stability, allowing the earphones to remain stable even when sweating, and reduces the risk of slipping. Furthermore, the concha piece 8 is removable and replaceable.

[0034] Preferably, the fin-shaped retaining plate 803 is made of silicone and has a molding wire embedded within it. The molding wire is made of metal. When the hearing aid is in use, the user can deform the fin-shaped retaining plate 803 according to the shape of their ear concha, thereby improving wearing comfort and preventing the hearing aid from slipping. It is understood that the connecting ring 802 is made of hard plastic or metal.

[0035] like Figure 3 As shown, in this embodiment, a plurality of slide grooves 601 are evenly provided on the inner wall of the extension tube 6, and a limit spring 602 is provided at one end of the plurality of slide grooves 601. The curved tube 4 extends to one end of the extension tube 6 and is provided with a protrusion 401 that cooperates with the slide groove 601 on the outside, and the protrusion 401 is slidably engaged with the inside of the slide groove 601.

[0036] Specifically, a slot 601 is defined on the inner wall of the extension tube 6, providing space for the protrusion 401 to move. A limit spring 602 is positioned at one end of the slot 601 to limit the position of the protrusion 401. By sliding the protrusion 401 at one end of the curved tube 4 within the slot 601, the user can adjust the relative length between the curved tube 4 and the extension tube 6, thereby varying the distance between the main unit 1 and the receiver 7 to accommodate different users' ears. In another embodiment, the limit spring 62 can be replaced by an elastic rubber block, which still provides a cushioning effect.

[0037] Furthermore, the curved tube 4 and the extension tube 6 are both made of thermoplastic polyurethane, which is a polymer material with excellent elasticity. It combines the elasticity of rubber and the processability of plastic. The curved tube 4 and the extension tube 6 are made of thermoplastic polyurethane, which can ensure that the earphones can fit the user's ear contour closely when worn, while maintaining sufficient flexibility to adapt to the ear shapes and sizes of different users. This flexibility also prevents the earphones from causing a sense of oppression to the user when worn for a long time, thereby improving the wearing comfort.

[0038] like Figure 5 As shown, in this embodiment, a plurality of metal wires 501 are embedded in the silicone sleeve 5, and the plurality of metal wires 501 are distributed in the silicone sleeve 5 in a mirror-symmetrical manner. The silicone sleeve 5 is mounted on the outside of the curved tube 4. Its soft and skin-friendly material can reduce the pressure on the ear and improve wearing comfort. The metal wires 501 embedded in the silicone sleeve 5 give it a shape memory function, that is, the silicone sleeve 5 can be adaptively adjusted according to the shape and size of the ears of different users, and at the same time, the shape of the curved tube 4 can follow the change. The silicone sleeve 5 can fit the contour of the ear closely, increasing the wearing stability and anti-slip performance.

[0039] Furthermore, the silicone sleeve 5 is at least partially sleeved on the outside of the curved tube 4, and the position of the silicone sleeve 5 is closely fitted to and covers the main contact area of ​​the ear hook on the user's ear.
