Description

Technical Field

[0001] This utility model belongs to the field of medical assistive device technology, specifically relating to a hearing aid anti-loss rope. Background Technology

[0002] A hearing aid is an assistive tool designed for people with hearing impairments. Its basic structure includes a mechanism, a housing, and a sound tube. The mechanism is the core component of the hearing aid, responsible for amplifying and processing sound; the housing protects the mechanism and provides a suitable appearance; and the sound tube guides sound to the hearing aid's microphone or output from the hearing aid. These components work together to enable the hearing aid to convert sound signals into electrical signals, amplify and process them, and then convert them back into acoustic signals, helping users hear sounds that were otherwise difficult to detect. Any hearing aid includes six basic structural components, primarily consisting of a microphone, amplifier, receiver, battery, and various volume and tone knobs.

[0003] Hearing aids are crucial assistive devices for people with hearing impairments, and their delicate and valuable nature makes them extremely easy to lose. Although there are anti-loss measures on the market, many of them have problems such as complicated operation and inconvenience in wearing. Utility Model Content

[0004] While existing technologies offer anti-loss measures, many suffer from problems such as complex operation and inconvenience in wearing. This invention provides an anti-loss cord for hearing aids.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A hearing aid anti-loss cord includes a neck connecting cord and a hearing aid connecting cord, which are connected at the middle. One end of the neck connecting cord is detachably connected to the other end. The two ends of the hearing aid connecting cord are respectively provided with a left connector and a right connector with the same structure. The left connector includes several elastic rings arranged sequentially on the hearing aid connecting cord. The elastic rings can be interference-fitted onto the hearing aid. Fixing rings are provided on both sides of the neck connecting cord where it connects to the hearing aid connecting cord. The fixing rings are fitted onto the neck connecting cord and the hearing aid connecting cord and are slidably connected to them.

[0007] With this technical solution, the hearing aid connects to the neck via a neck strap, and the hearing aid is connected to the neck via elastic loops on the strap. This is convenient and simple to use, effectively preventing the hearing aid from being lost. Furthermore, considering that the elasticity of the loops weakens over time, resulting in a poor connection with the hearing aid, this invention incorporates multiple elastic loops on the neck strap. When the elasticity of the end loop weakens, it can be cut off, and a second elastic loop can be used. At this point, the fixing ring can be moved to release the hearing aid connecting strap from the neck strap, thereby adjusting the distance between the second elastic loop and the ear. This avoids the hearing aid connecting strap being too long and prone to tangling, and allows adjustment of the distance between each elastic loop and the ear. It does not add complexity to the structure while ensuring the long-term effectiveness of the hearing aid anti-loss strap. Additionally, after removing the hearing aid, the fixing ring can be moved closer to the end of the neck strap to store the hearing aid connecting strap, preventing the two ends from tangling.

[0008] Preferably, both the neck strap and the hearing aid strap are silicone straps, and the fixing ring is a silicone ring that can be interference-fitted onto the neck strap and the hearing aid strap.

[0009] With this technology, the hearing aid anti-loss cord is made entirely of flexible material, which will not irritate the patient during use and improves comfort.

[0010] Preferably, the two ends of the neck connecting rope are respectively provided with a first magnet and a second magnet, and the first magnet and the second magnet can be connected by magnetic force.

[0011] With this technical solution, the detachable connection of the two ends of the neck rope can be achieved by magnetic force without any additional operation. Simply bring the first and second magnets close together, which is easy to do.

[0012] Preferably, the first magnet is a cylindrical structure, the second magnet is larger than the first magnet, and the second magnet is provided with a cavity for accommodating the first magnet. The front and rear ends of the second magnet are respectively provided with a first opening that matches the size of the first magnet and a second opening that matches the size of the neck connecting rope. The side wall of the second magnet has a third opening that communicates with the cavity, and the size of the third opening matches the size of the neck connecting rope.

[0013] With this technical solution, simply connecting by magnetic force may cause the first and second magnets to separate when the neck connecting rope is accidentally pulled, making the hearing aid easy to lose. Therefore, this utility model further provides the second magnet with a receiving cavity that can be used to accommodate the first magnet. The first magnet can be inserted into the receiving cavity through the cooperation of three openings, thereby improving the connection effect between the first and second magnets.

[0014] Preferably, the inner surface of each elastic ring is provided with several grooves.

[0015] With this technical solution, several grooves are set on the elastic ring. When the elastic ring is connected to the hearing aid, the air in the grooves is forced out by the elasticity of the elastic ring itself, forming a negative pressure, thereby enhancing the connection effect between the elastic ring and the hearing aid.

[0016] Preferably, the width of the elastic ring is 0.5-1cm.

[0017] With this technical solution, the length of the elastic ring refers to the height of the curved surface of the elastic ring. If the elastic ring is too long, it will affect the normal use of the hearing aid, and if it is too short, the connection effect will be poor. Therefore, it is set to 0.5-1cm.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, the hearing aid is connected to the neck via a neck connecting cord, and can be connected to the hearing aid via elastic rings on the hearing aid connecting cord. It is convenient to use and simple to operate, and can effectively prevent the hearing aid from being lost. In addition, considering that the elasticity of the elastic rings weakens after long-term use, resulting in poor connection with the hearing aid, this utility model is equipped with multiple elastic rings on the neck connecting cord. When the elasticity of the end elastic ring weakens, the end elastic ring can be directly cut off and the second elastic ring can be used. At this time, the fixing ring can be moved to release the hearing aid connecting cord from the neck connecting cord, thereby adjusting the distance from the second elastic ring to the ear. This avoids the hearing aid connecting cord being too long and prone to tethering, and ensures that each elastic ring can reach the ear. It does not add a complicated structure, and ensures the long-term effectiveness of the hearing aid anti-loss cord.

[0020] 2. In this utility model, because a fixing ring is provided, after the hearing aid is removed, the fixing ring can be moved to the end near the neck connecting rope to store the hearing aid connecting rope and prevent the two ends of the hearing aid connecting rope from getting tangled together.

Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] The following is combined Figures 1-4 This utility model will be described in detail.

[0030] Example 1

[0031] like Figure 1As shown, a hearing aid anti-loss cord includes a neck connecting cord 1 and a hearing aid connecting cord 2. The neck connecting cord 1 and the hearing aid connecting cord 2 are connected at the middle, and one end of the neck connecting cord 1 is detachably connected to the other end. The two ends of the hearing aid connecting cord 2 are respectively provided with a left connector and a right connector with the same structure. The left connector includes several elastic rings 5 ​​arranged sequentially on the hearing aid connecting cord 2. The elastic rings 5 ​​can be interference-fitted onto the hearing aid 4. Fixing rings 3 are provided on both sides of the connection point between the neck connecting cord 1 and the hearing aid connecting cord 2. The fixing rings 3 are fitted on the neck connecting cord 1 and the hearing aid connecting cord 2 and can be slidably connected to the neck connecting cord 1 and the hearing aid connecting cord 2.

[0032] In this embodiment, as Figure 1 As shown, both the neck connecting cord 1 and the hearing aid connecting cord 2 are silicone cords (in other embodiments, the neck connecting cord 1 and the hearing aid connecting cord 2 can also be made of flexible materials such as rubber cords or cotton cords). The fixing ring 3 and the elastic ring 5 are silicone rings. The fixing ring 3 can be interference-fitted onto the neck connecting cord 1 and the hearing aid connecting cord 2, and the elastic ring 5 can be interference-fitted onto the hearing aid 4. The interference fit means that when the elastic ring 5 is fitted onto the hearing aid 4, it is in a stretched state, and the inner surface of the elastic ring 5 is in close contact with the hearing aid 4. The friction between the elastic ring 5 and the hearing aid 4 keeps them tightly connected. Similarly, the fixing ring 3 can be interference-fitted onto the neck connecting cord 1 and the hearing aid connecting cord 2. Since the fixing ring 3 is connected to the neck connecting cord 1 and the hearing aid connecting cord 2 through friction, the fixing ring 3 can slide relative to the neck connecting cord 1 and the hearing aid connecting cord 2 under the action of external force. Of course, if comfort is not a consideration, in other embodiments the neck connecting rope 1 and / or fixing ring 3 can also be made of rigid materials such as plastic.

[0033] In this embodiment, a first magnet 6 and a second magnet 7 are respectively provided at both ends of the neck connecting rope 1. The first magnet 6 and the second magnet 7 attract each other magnetically, and the first magnet 6 and the second magnet 7 can be connected by magnetic force.

[0034] In this embodiment, the width of the elastic ring 5 is 0.5 cm, and the thickness of the elastic ring 5 is 1 mm.

[0035] In this embodiment, three elastic rings 5 ​​are provided, and the distance between two adjacent elastic rings 5 ​​is 1cm. When the elastic force of the end elastic ring weakens to the point that it can no longer meet the fixing requirements, the hearing aid connecting rope 2 between two adjacent elastic rings 5 ​​can be cut. Since the hearing aid connecting rope 2 is made of silicone, it can be cut smoothly.

[0036] Reference Figure 1In use, the user first passes the hearing aid 4 through the elastic ring 5, so that the elastic ring 5 is fitted in the middle of the hearing aid 4. The elastic ring 5, in a stretched state, connects to the hearing aid 4 through friction, forming a... Figure 1 The user can then adjust the length of the hearing aid cord 2 as shown in the diagram. If the cord is too long, the user can slide the retaining ring 3 towards the first magnet 6 to secure the excess hearing aid cord 2 to the neck cord 1. If the cord is too short, the user can slide the retaining ring towards the connection point between the hearing aid cord 2 and the neck cord 1 to release the portion of the neck cord 1 that is in contact with it. This prevents the hearing aid cord 2 from being too long and accidentally getting caught. This method is also suitable for patients with different neck lengths. After adjusting the length, the user can place the neck cord 1 around the neck. The magnetic force between the first magnet 6 and the second magnet 7 connects the two ends of the neck cord 1, forming a loop around the user's neck. Finally, the user can wear the hearing aid 4 connected to the elastic ring 5. If the elastic ring 5 ages and loses its elasticity after a period of use, the end of the elastic ring can be cut off and a second elastic ring used. At this time, the fixing ring can be moved to release the hearing aid connecting cord 2 from the neck connecting cord 1, thereby adjusting the distance between the second elastic ring 5 and the ear to meet wearing requirements. After removing the hearing aid 4, the fixing ring 3 can be moved closer to the end of the neck connecting cord 1 to store the hearing aid 4 connecting cord and prevent the two ends of the hearing aid connecting cord 2 from tangling.

[0037] Example 2

[0038] This embodiment is basically the same as Embodiment 1, except that: Figure 2 As shown, the first magnet 6 has a cylindrical structure, the second magnet 7 is larger than the first magnet 6, and the second magnet 7 has a cavity for accommodating the first magnet 6. The front and rear ends of the second magnet 7 are respectively provided with a first opening 8 that matches the size of the first magnet 6 and a second opening 9 that matches the size of the neck connecting rope 1. Figure 4As shown, the diameter of the first opening 8 is slightly larger than the diameter of the first magnet 6, allowing the first magnet 6 to enter the receiving cavity. The diameter of the second opening 9 is larger than the diameter of the neck connecting rope 1 but smaller than the diameter of the first magnet 6, allowing the neck connecting rope 1 to pass through the second opening 9, but preventing the first magnet 6 from passing through. Therefore, when pulled, the first magnet 6 cannot detach from the receiving cavity. A third opening 10 communicating with the receiving cavity is opened on the side wall of the second magnet 7. The size of the third opening 10 matches the size of the neck connecting rope 1. Both the first opening 8 and the second opening 9 communicate with the third opening 10. The width of the third opening 10 is larger than the diameter of the neck connecting rope 1 but smaller than the diameter of the first magnet 6, allowing the neck connecting rope 1 to enter the second opening from the third opening 10 during the process of the first magnet 6 entering the receiving groove.

[0039] Example 3

[0040] This embodiment is basically the same as embodiment 1 or 2, except that: Figure 3 As shown, each of the elastic rings 5 ​​has several grooves 11 on its inner surface. With several grooves 11 on the elastic ring 5, when the elastic ring 5 is connected to the hearing aid 4, the air in the grooves 11 is forced out by the elastic force of the elastic ring 5 itself, forming a negative pressure, thereby enhancing the connection effect between the elastic ring 5 and the hearing aid 4.

[0041] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
