Description

Technical Field

[0001] This utility model relates to the field of hearing aid accessories technology, and in particular to a hearing aid earplug structure with high comfort. Background Technology

[0002] Hearing aids compensate for and amplify sound for people with hearing loss, enabling them to better perceive speech and ambient sounds, thereby improving their participation and quality of communication, learning, and work. Essentially, it's a small electronic medical device; it doesn't restore damaged hearing, but rather makes full use of residual hearing to make sound clearer and more intelligible. To improve the seal and achieve noise reduction, many hearing aids on the market use an in-ear design, with an in-ear headpiece and earplug structure.

[0003] However, traditional hearing aid earplugs have a simple structure, and earplugs of a single size or fixed shape are difficult to match the ear canal structure of different users. In order to ensure a tight fit, users need to press the earplugs tightly. Such compression and sealing of the ear canal during long-term wear can easily cause discomfort during the wearing process. For example, although some hearing aid brands offer different sizes of ear tips for users to choose from, the fixed structure of the ear tips can never effectively match the ear canal structure of most users, resulting in poor fit during the selection process. Utility Model Content

[0004] This utility model discloses a highly comfortable hearing aid earplug structure, aiming to solve the technical problems of traditional hearing aid earplug structures being simple to set, with single-size or fixed-shape earplugs that are difficult to match the ear canal structures of different users. In order to ensure a tight fit, users need to press the earplug tightly, and the compression and closure of the ear canal during such long-term wear can easily cause discomfort during the wearing process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A comfortable hearing aid earbud structure includes an earphone head and an earbud body and an earphone cable connected to the earphone head. The earbud body includes an outer earbud and an inner earbud, and an adjustment component is provided between the outer earbud and the inner earbud. The adjustment assembly includes a connection structure disposed inside the outer earplug. The connection structure consists of a sleeve and a threaded portion. The inner wall of the inner earplug is provided with an inner sleeve, which is adapted to the threaded portion. A retaining ring is provided at the end of the threaded portion away from the sleeve.

[0006] By adopting the above technical solution, the distance between the inner and outer earplugs can be finely adjusted by adjusting the component. In actual use, the inner earplug can be adjusted according to the ear canal structure of different users. The inner sleeve of the inner wall of the inner earplug can be rotated and finely adjusted with the threaded part. Under the limitation of the threaded trajectory, the rotation adjustment can control the inner earplug to move closer to or further away from the outer earplug. In this process, the outer earplug can block the user's ear canal opening. Together with the inner earplug that is inserted to a suitable depth, they maintain the connection between the hearing aid and the ear canal. The highly adaptable contact connection effectively improves comfort.

[0007] As a further embodiment of this utility model: the inner earplug has vent holes that are equidistantly distributed in a circular pattern, and the vent holes are located in the inner ring portion of the inner earplug.

[0008] By adopting the above technical solution, the ventilation hole opened in the inner ring will not be blocked when the inner earplug is pressed against the ear canal. It is far away from the squeezing contact part between the inner earplug and the ear canal, thus ensuring ventilation to a certain extent. It should be noted that there is no hole on the outer earplug, so the ventilation between the outer earplug and the outside world mainly relies on the gap formed by the movement of the ear canal when the user speaks, thus maximizing the effect of the hearing aid.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. Strong adaptability: Unlike traditional single-structure hearing aid earplugs, the dual-layer earplugs in this solution, combined with the adjustable design of the adjustment components, ensure that the hearing aid earplugs can fit the user's ear canal more closely, thereby improving the comfort of use.

[0010] 2. High comfort: The coordinated fixation of the double-layer earplugs can improve connection stability while maintaining comfort. The air holes on the inner earplug and the gaps created by the outer earplug when the auricle moves work together to optimize the ventilation of the ear canal and further ensure that the ear canal is dry and comfortable.

[0011] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 , Figure 2 and Figure 3 A comfortable hearing aid earplug structure includes an earphone head 2 and an earplug body and an earphone cable 1 connected to the earphone head 2. The earplug body includes an outer earplug 3 and an inner earplug 4, and an adjustment component is provided between the outer earplug 3 and the inner earplug 4. The adjustment assembly includes a connection structure disposed inside the outer earplug 3. The connection structure consists of a sleeve portion 8 and a threaded portion 9. The inner wall of the inner earplug 4 is provided with an inner sleeve 10, which is adapted to the threaded portion 9. A retaining ring is provided at the end of the threaded portion 9 away from the sleeve portion 8.

[0018] The retaining ring design prevents the inner earplug 4 from being dislodged from the threaded part 9 due to excessive adjustment.

[0019] Specifically, the distance between the inner earplug 4 and the outer earplug 3 can be finely adjusted by adjusting the component. In actual use, the inner earplug 4 can be adjusted according to the ear canal structure of different users. The inner sleeve 10 of the inner wall of the inner earplug 4 can be rotated and finely adjusted with the threaded part 9. Under the limitation of the threaded trajectory, the rotation adjustment can control the inner earplug 4 to move closer to or further away from the outer earplug 3. In this case, the outer earplug 3 can block the user's ear canal opening. Together with the inner earplug 4 with a suitable insertion depth, they maintain the connection between the hearing aid and the ear canal. The highly adaptable contact connection effectively improves comfort.

[0020] The outer earplug 3 is larger than the inner earplug 4.

[0021] It should be noted that the threaded part 9, the sleeve part 8, and the inner sleeve 10 are all made of hard silicone material, while the outer earplug 3 and the inner earplug 4 are both made of soft silicone material.

[0022] The inner sleeve 10 made of hard silicone material can be adjusted on the threaded part 9 of hard silicone material, while the inner earplug 4 and outer earplug 3 made of soft silicone material can ensure the tactile feel of contact with the skin and ensure comfort.

[0023] Reference Figure 3 In a preferred embodiment, a sound tube is connected to one side of the earphone head 2, and a sound tube connector 7 is provided at one end of the sound tube. A sleeve 8 is sleeved on the outer wall of the sound tube connector 7, and the sleeve 8 is connected to the outer earplug 3. The inner sleeve 10 is connected to the inner earplug 4.

[0024] Reference Figure 2 and Figure 3 In a preferred embodiment, the inner earplug 4 has vent holes 6 that are equidistantly distributed in a circular pattern, and the vent holes 6 are located in the inner ring portion of the inner earplug 4.

[0025] Specifically, the ventilation hole 6 on the inner ring will not be blocked when the inner earplug 4 is pressed tightly against the ear canal. It is far away from the squeezing contact part between the inner earplug 4 and the ear canal, thus ensuring ventilation to a certain extent. It should be noted that there is no hole on the outer earplug 3. Therefore, the ventilation between the outer earplug 3 and the outside world mainly relies on the gap formed by the movement of the ear canal when the user speaks, thus maximizing the effect of the hearing aid.

[0026] The top of the threaded part 9 is connected to a filter plug 5, which can prevent dirt and debris in the ear canal from entering the sound tube and causing hearing aid malfunction.

[0027] Working principle: When using, the user first ensures that the ear canal is clean, then installs the earplug body onto the sound tube connector 7 on the earphone head 2, adjusts the position of the inner earplug 4 on the threaded part 9, and finds the appropriate position for the double earplug to connect with the ear canal through multiple attempts, and then turns on the hearing aid. After using it for a period of time, the position of the inner earplug 4 can also be finely adjusted again to avoid discomfort caused by pressing against one place for a long time.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
