Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, and in particular to a stable flexible earmold, earmold assembly and hearing aid. Background Technology

[0002] Hearing aids are devices that provide hearing assistance to people with hearing impairments. The earmold is one of the key components of a hearing aid, used to directly insert into the ear canal to transmit sound. Flexible earmolds are made of flexible materials, thus offering greater comfort compared to rigid earmolds. To ensure a continuous flow of sound into the ear, the earmold needs to be stable within the ear. Currently, flexible earmolds are usually custom-made to fit the shape of the user's ear canal, relying on friction between the earmold and the ear canal for stability. However, for universal earmolds, the shape sometimes cannot perfectly conform to the ear canal, potentially causing them to fall out during use, resulting in poor stability and impacting the user experience. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a stable flexible earmold, earmold assembly and hearing aid, which has the advantage of improving wearing stability.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] According to a first aspect of the present disclosure, a stable flexible earmold is provided, comprising:

[0006] An earmold body made of flexible material has a mounting cavity for inserting and fixing a receiver, and a sound guide hole communicating with the mounting cavity is provided at the front end of the earmold body; and,

[0007] A positioning support foot is integrally formed at the rear end of the ear mold body and is adapted to the contour of the concha cavity. The end of the positioning support foot is formed with a deformable hook for the human hand to pinch and remove the ear mold from the human ear.

[0008] To achieve the above technical solution, during installation, the receiver is inserted into the mounting cavity. The receiver and the mounting cavity are fixed by frictional damping. When the earmold is worn in the ear, the earmold body first undergoes a certain elastic deformation upon contact with the ear canal, which allows the earmold body to be initially fixed in the ear. Secondly, because the positioning feet match the contour of the concha, they can provide support for the earmold body when it is embedded in the concha, so that the earmold is stably positioned in the ear. The sound is transmitted through the receiver and enters the ear through the sound guide hole to achieve the hearing aid function. Since the claws are easily deformed, when it is necessary to remove the earmold, the earmold can be removed by pinching the claws, rather than by pulling the receiver's wire, thus avoiding damage to the wire.

[0009] In some exemplary embodiments, a limiting step is formed between the mounting cavity and the tone guide hole to limit the mounting position of the receiver.

[0010] The above technical solution enables the rapid installation of positioning receivers.

[0011] In some exemplary embodiments, the mounting cavity is capable of elastic deformation to tighten the receiver.

[0012] The above technical solution makes the receiver more stable.

[0013] In some exemplary embodiments, the front end of the earmold body has an arc-shaped transition, and the sound guide hole is disposed on the front end surface of the earmold body.

[0014] The above technical solution facilitates the insertion of the earmold into the ear and the transmission of sound into the ear.

[0015] In some exemplary embodiments, the hook extends along the arc direction of the positioning leg, and the end of the hook is rounded.

[0016] The above technical solution facilitates the molding of the hook and makes it more comfortable when the hook is inserted into the concha cavity.

[0017] According to a second aspect of the present disclosure, an earmold assembly is provided, comprising: a stable flexible earmold as described in the first aspect, and a receiver connected to an external host via a wire.

[0018] According to a third aspect of the present disclosure, a hearing aid is provided, comprising: an earmold assembly as described in the second aspect, and an external host, the external host being configured to receive and process external sound signals, and transmit the processed sound signals to a human ear via the receiver.

[0019] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0020] This utility model embodiment provides a stable flexible earmold, an earmold assembly, and a hearing aid. The stable flexible earmold includes: an earmold body made of flexible material, with an installation cavity for inserting and fixing a receiver, and a sound guide hole communicating with the installation cavity at the front end of the earmold body; and a positioning support foot integrally formed at the rear end of the earmold body and adapted to the contour of the concha cavity, with a deformable hook at the end of the positioning support foot for hand-pinching and removing the earmold from the ear. During installation, the receiver is inserted into the mounting cavity. The receiver and the mounting cavity are fixed in place by frictional damping. When the earmold is worn in the ear, the earmold body first undergoes a certain elastic deformation upon contact with the ear canal, which allows the earmold body to be initially fixed in the ear. Secondly, because the positioning feet match the contour of the concha, they can provide support for the earmold body when it is embedded in the concha, so that the earmold is stably positioned in the ear. The sound is transmitted through the receiver and enters the ear through the sound guide hole to achieve the hearing aid function. Since the claws are easily deformed, when it is necessary to remove the earmold, the earmold can be removed by pinching the claws, rather than by pulling the receiver's wire, to avoid damage to the wire.

[0025] 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.

[0026] like Figure 1 and Figure 2As shown, the first aspect of this utility model provides a stable flexible earmold, including: an earmold body 10 made of flexible material, an earmold body 10 having an installation cavity 11 for inserting and fixing a receiver, and a sound guide hole 12 communicating with the installation cavity 11 at the front end of the earmold body 10; and a positioning support 20 integrally formed at the rear end of the earmold body 10 and adapted to the contour of the concha cavity, the end of the positioning support 20 having a deformable hook 21 for allowing a person to pinch and remove the earmold from the ear.

[0027] Both the earmold body 10 and the positioning foot 20 can be made of transparent silicone material. The shape of the earmold body 10 can be obtained by collecting a large number of ear canal shapes and modifying them to form a universal earmold body 10 shape. It can be understood that the mounting cavity 11 is a space formed inside the earmold body 10 and opening at the rear end of the earmold body 10. The receiver can be inserted and fixed in the mounting cavity 11 through the opening. A limiting step 13 is formed between the mounting cavity 11 and the tone hole 12 to limit the installation position of the receiver. During installation, the receiver is inserted until it abuts against the limiting step 13, so that the receiver can be quickly installed and positioned.

[0028] The mounting cavity 11 can generate elastic deformation to tighten the receiver. It is understood that this elastic deformation capability is brought about by the molding of the earmold body 10, thereby making the receiver more stable. Usually, by sampling and statistically analyzing the sizes of receivers sold on the market, the mode or median of the receiver size can be selected as the size of the mounting cavity 11, so as to be able to accommodate the installation of most receivers of various sizes.

[0029] The front end of the earmold 10 has an arc-shaped transition, and the sound guide hole 12 is provided on the front end surface of the earmold 10 so as to insert the earmold 10 into the ear and facilitate the sound to enter the ear. The hook 21 extends along the arc direction of the positioning foot 20, and the end of the hook 21 is rounded to facilitate the shaping of the hook 21 and make the hook 21 more comfortable when it is embedded in the concha cavity.

[0030] During installation, the receiver is inserted into the mounting cavity 11. The receiver and the mounting cavity 11 are fixed by frictional damping. When the earmold is worn in the ear, the earmold body 10 will first undergo a certain elastic deformation when it comes into contact with the ear canal, so that the earmold body 10 can be initially fixed in the ear. Secondly, since the positioning foot 20 matches the contour of the concha cavity, it can support the earmold body 10 when it is embedded in the concha cavity, so that the earmold is stably positioned in the ear. Even if the earmold body 10 does not fit the ear canal perfectly, it can still be stably fixed in the ear by the support of the positioning foot and the hook 21. The sound is transmitted through the receiver and enters the ear through the sound guide hole 12 to realize the hearing aid function. Since the hook 21 is easy to deform, when it is necessary to remove the earmold, the earmold can be removed by pinching the hook 21, rather than by pulling the receiver wire, so as to avoid damage to the wire.

[0031] A second aspect of this utility model provides an earmold assembly, including: a stable flexible earmold as described in the first aspect, and a receiver, the receiver being connected to an external host via a wire, the receiver being fitted into an installation cavity 11 and abutting against a limiting step 13.

[0032] The third aspect of this utility model provides a hearing aid, including: an earmold assembly as described in the second aspect, and an external host. The external host is used to receive and process external sound signals, and transmit the processed sound signals to the human ear via a receiver. The structure and function of the external host are prior art and will not be described in detail here.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
