Description

Technical Field

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

[0002] As an accessory for hearing aids, an earmold is typically placed in the user's external auditory canal to deliver sound emitted by the hearing aid's speaker into the user's ear canal.

[0003] Existing ear molds generally include universal ear molds and custom ear molds. Because universal ear molds have fixed sizes, while different users have different ear canal structures and sizes, they can easily cause discomfort or ear molds to fall off when worn. Custom ear molds are more expensive and require higher processing precision. Therefore, existing ear molds are usually not suitable for different users. Utility Model Content

[0004] Therefore, it is necessary to provide an earmold and hearing aid to address the above problems and improve the adaptability of the earmold.

[0005] This utility model first provides an ear mold, including: a fixing part with a speaker mounting hole; and an insertion part connected to one end of the fixing part, wherein the insertion part has a sound transmission hole communicating with the speaker mounting hole; wherein the fixing part and the insertion part are both made of soft silicone, and the soft silicone has a Shore hardness of 20 to 40 degrees.

[0006] In the aforementioned earmold, the soft silicone component has a low Shore hardness and good ductility and plasticity. Therefore, when wearing the earmold, the user can freely adjust the shape of the earmold and the angle and depth of insertion according to the shape of the ear canal. This allows the outer surface of the fixing part to completely fit the user's external auditory canal opening, stably fixing the fixing part to the user's external auditory canal opening. At the same time, it prevents sound leakage from gaps between the fixing part and the user's external auditory canal opening, avoiding feedback howling. The insertion part can extend into the user's ear canal to guide the sound emitted by the speaker into the user's ear canal through the sound transmission hole. In this way, the earmold can be used by different users, improving the adaptability of the earmold and reducing the overall cost of the earmold and hearing aid. Furthermore, speakers of different sizes and shapes can be inserted into the speaker mounting hole through interference fit to ensure the stability and reliability of the speaker fixed in the speaker mounting hole.

[0007] In one embodiment, the cross-sectional dimension of the extended portion gradually decreases from the end near the fixed portion toward the end away from the fixed portion.

[0008] With this design, after the insertion part is inserted into the user's ear canal, the outer surface of the insertion part does not contact the wall of the user's ear canal, avoiding sound wave reflection or energy loss, thereby ensuring the sound transmission efficiency and sound transmission effect of the sound transmission hole.

[0009] In one embodiment, the extension is configured as a cone shape.

[0010] This design simplifies the structure of the conical insertion part, making it easier to manufacture ear molds and allowing it to better fit ear canals of different structures and sizes. Furthermore, the smooth outer surface of the conical insertion part enhances user comfort when wearing the ear mold.

[0011] In one embodiment, the sound transmission hole includes an equal diameter section and a gradually expanding section that are interconnected. The end of the equal diameter section away from the gradually expanding section is connected to the speaker mounting hole. The cross-sectional size of the gradually expanding section gradually increases from the end closer to the equal diameter section toward the end away from the equal diameter section.

[0012] With this design, the expanding section can guide sound waves into the ear canal with a wider diffusion angle, avoiding excessive concentration of sound energy at a certain point, thereby reducing sound absorption by the ear canal wall and improving the naturalness of the sound; in addition, the expanding section also makes it easier to process the sound transmission hole from the end of the extension part away from the fixed part.

[0013] In one embodiment, the center line of the sound transmission hole coincides with the center line of the extension portion.

[0014] This design places the sound transmission hole in the center of the user's ear canal, thereby reducing the scattering or reflection of sound waves due to collisions with the ear canal wall, ensuring the efficiency and effectiveness of sound transmission within the user's ear canal; it also facilitates the processing of the sound transmission hole in the insertion part.

[0015] In one embodiment, the cross-sectional dimension of the fixing part gradually decreases from the end away from the extension part toward the end closer to the extension part; and / or, the outer surface of the fixing part is smoothly connected to the outer surface of the extension part.

[0016] This design, with its gradually decreasing cross-sectional dimensions, allows the shape of the fixing part to better fit the structure of the user's external auditory canal, enabling the outer surface of the fixing part to better conform to the wall of the user's external auditory canal, avoiding feedback whistling. Furthermore, the user can control the insertion depth of the fixing part according to the size of their own external auditory canal to achieve a secure and comfortable fit, thereby improving the adaptability of the earmold. The smooth connection between the outer surface of the fixing part and the outer surface of the insertion part makes the overall outer surface of the fixing part and the insertion part smooth, thus improving the user's comfort when wearing the earmold.

[0017] In one embodiment, the ear mold further includes a support portion connected to the end of the fixing portion away from the insertion portion, the support portion being configured as a soft silicone material.

[0018] With this design, the support part can abut against the user's auricle, providing support for the entire earmold and preventing the fixing part from loosening or coming out of the ear canal, thereby improving the stability and comfort of the user when wearing the earmold. Furthermore, when wearing the earmold, the user can adjust the shape of the support part according to the distance between the external auditory canal and the auricle, as well as the shape of the auricle, so that the earmold can be adapted to different users, thus improving the adaptability of the earmold.

[0019] In one embodiment, the support portion is provided with weight-reducing holes; and / or, the support portion is arc-shaped.

[0020] This design allows the weight-reducing holes to decrease the overall weight of the earmold, improving user comfort when wearing it. The weight-reducing holes also make it easier for users to pick up or put on the earmold. The curved support part is more compatible with the shape of the user's auricle, increasing the contact area between the support part and the user's auricle, thereby improving the support effect and comfort of the support part.

[0021] In one embodiment, the fixing part, the extending part, and the supporting part are integrally formed.

[0022] This design facilitates the production and processing of ear molds, ensures the stability and reliability of the connection between the fixing part, the insertion part and the support part, and improves the overall integrity and consistency of the ear mold, thereby enhancing the aesthetics and wearing comfort of the ear mold.

[0023] This invention also provides a hearing aid, including the earmold described above. Attached Figure Description

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0036] As accessories for hearing aids, earmolds are typically placed in the user's outer ear canal to deliver sound from the hearing aid's speaker into the ear canal. Existing earmolds generally include universal earmolds and custom earmolds. Because universal earmolds have fixed sizes, and different users have different ear canal structures and sizes, discomfort or earmold dislodgement can easily occur. For example, if a universal earmold is too large, it may cause pressure on the user's ear canal; if it is too small and cannot fit well at the user's ear canal opening, feedback whistling may occur, affecting the hearing aid's effectiveness. Custom earmolds, on the other hand, are more expensive and require higher manufacturing precision; therefore, existing earmolds are generally not suitable for all users.

[0037] To solve the above problems, such as Figures 1 to 5 As shown, this utility model provides an earmold and a hearing aid to improve the adaptability of the earmold.

[0038] like Figures 1 to 3 As shown, specifically, the earmold includes a fixing part 1 and an insertion part 2, wherein: the fixing part 1 is provided with a horn mounting hole 11, which is used to install the horn of the hearing aid (not shown); the insertion part 2 is connected to one end of the fixing part 1, and the insertion part 2 is provided with a sound transmission hole 21 communicating with the horn mounting hole 11; both the fixing part 1 and the insertion part 2 are made of soft silicone, and the Shore hardness of the soft silicone is 20 to 40 degrees.

[0039] In the earmold provided by this embodiment of the utility model, because the soft silicone part has a low Shore hardness and good ductility and plasticity, the user can freely adjust the shape of the earmold and the angle and depth of insertion according to the shape of the ear canal when wearing the earmold. This allows the outer surface of the fixing part 1 to fit completely against the wall of the user's external ear canal, so as to stably fix the fixing part 1 to the user's external ear canal opening. At the same time, it prevents sound leakage from the gap between the fixing part 1 and the user's external ear canal opening, thus avoiding feedback howling. The insertion part 2 can be inserted into the user's ear canal to guide the sound emitted by the speaker into the user's ear canal through the sound transmission hole 21. In this way, the earmold can be used by different users, thereby improving the adaptability of the earmold and reducing the overall cost of the earmold and hearing aid.

[0040] And, as Figure 2 As shown, the fixing part 1 is made of soft silicone, which allows speakers of different sizes and shapes to be inserted into the speaker mounting hole 11 through an interference fit, and ensures the stability and reliability of the speaker fixed in the speaker mounting hole 11. The cross-section of the speaker mounting hole 11 can be... Figure 3 The square shown can also be in the form of Figure 5 The circle shown can also be in the form of a triangle, trapezoid, or other regular or irregular shapes, as long as the stability and reliability of the speaker within the speaker mounting hole 11 can be guaranteed. This embodiment of the present invention does not impose any specific limitations.

[0041] The Shore hardness of the soft silicone part can be any hardness in the range of 20 to 40 degrees, such as 20 degrees, 25 degrees, 30 degrees, 35 degrees, and 40 degrees, preferably 30 degrees, to ensure the ductility and plasticity of the soft silicone part, while ensuring the seal between the fixing part 1 and the user's external auditory canal.

[0042] like Figure 1 As shown, in one embodiment, the cross-sectional dimension of the insertion portion 2 gradually decreases from the end near the fixing portion 1 towards the end away from the fixing portion 1. Here, the cross-sectional dimension of the insertion portion 2 refers to the total cross-sectional area of ​​the insertion portion 2, including the cross-sectional area of ​​the sound transmission hole 21. Thus, after the insertion portion 2 is inserted into the user's ear canal, the outer surface of the insertion portion 2 does not contact the user's ear canal wall, avoiding sound wave reflection or energy loss, thereby ensuring the sound transmission efficiency and sound transmission effect of the sound transmission hole 21.

[0043] The insertion part 2 can be cone-shaped. A cone-shaped insertion part 2 has a simple structure, facilitating the production and processing of earmolds, and also allows it to better fit ear canals of different structures and sizes. Furthermore, the smooth outer surface of the cone-shaped insertion part 2 improves user comfort when wearing the earmold. It should be noted that the cone shape includes straight cones and oblique cones, and the outer surface of the insertion part 2 can be arched, with the end of the insertion part 2 away from the fixing part 1 having rounded corners to further improve user comfort. Alternatively, the insertion part 2 can also be shaped like a frustum, pyramid, or other regular or irregular shapes, as long as it ensures that the outer surface of the insertion part 2 does not contact the ear canal wall after it is inserted into the user's ear canal. This embodiment of the invention does not impose specific limitations here.

[0044] Of course, in other embodiments, the cross-sectional dimensions of the insertion part 2 can remain unchanged; for example, the insertion part 2 can be cylindrical. Furthermore, the cross-sectional dimensions of the insertion part 2 are smaller than the cross-sectional dimensions of the fixing part 1, so that after the insertion part 2 is inserted into the user's ear canal, the outer surface of the insertion part 2 does not contact the wall of the user's ear canal.

[0045] like Figure 4 As shown, in one embodiment, the sound transmission hole 21 includes an equal-diameter section 211 and a gradually expanding section 212 that are interconnected. The end of the equal-diameter section 211 away from the gradually expanding section 212 is connected to the speaker mounting hole 11. The cross-sectional dimension of the gradually expanding section 212 gradually increases from the end closer to the equal-diameter section 211 towards the end away from the equal-diameter section 211. The cross-sectional dimension of the gradually expanding section 212 refers to its cross-sectional area. The sound emitted by the speaker is sequentially introduced into the user's ear canal through the equal-diameter section 211 and the gradually expanding section 212. The gradually expanding section 212 can guide the sound waves into the ear canal with a wider diffusion angle, avoiding excessive concentration of sound energy at a single point, thereby reducing sound absorption by the ear canal wall and improving the naturalness of the sound. Furthermore, the gradually expanding section 212 also facilitates the machining of the sound transmission hole 21 from the end of the insertion portion 2 away from the fixing portion 1. Of course, in other embodiments, the sound transmission hole 21 may only include the equal-diameter section 211, or the sound transmission hole 21 may only include the gradually expanding section 212.

[0046] Preferably, the cross-section of the sound transmission hole 21 is circular, making the inner wall of the sound transmission hole 21 smooth and reducing sound loss during transmission within the sound transmission hole 21. Furthermore, when the cross-section of the sound transmission hole 21 is circular, the inner diameter of the constant diameter section 211 remains unchanged, while the inner diameter of the gradually expanding section 212 gradually increases.

[0047] like Figure 4As shown, in one embodiment, the centerline of the sound transmission hole 21 coincides with the centerline of the extension portion 2. Specifically, when both the extension portion 2 and the sound transmission hole 21 have circular cross-sections, the centerline of the extension portion 2 is the axis of the sound transmission hole 21, and the centerline of the sound transmission hole 21 is also the axis of the sound transmission hole 21. Furthermore, the shortest distance between any point on the inner wall of the sound transmission hole 21 and the outer wall of the extension portion 2 is always equal. This ensures that the sound transmission hole 21 is located at the center of the user's ear canal, thereby reducing scattering or reflection caused by sound waves colliding with the ear canal wall, ensuring efficient and effective sound transmission within the user's ear canal. It also facilitates the processing of the sound transmission hole 21 within the extension portion 2. It should be noted that the coincidence of the centerline of the sound transmission hole 21 with the centerline of the extension portion 2 means that the centerline of the sound transmission hole 21 and the centerline of the extension portion 2 are completely or approximately coincident; the influence of manufacturing errors is ignored here.

[0048] Of course, in other embodiments, the center line of the sound transmission hole 21 may also be at an angle to or parallel to the center line of the extension portion 2, as long as it does not affect the normal transmission of sound in the sound transmission hole 21. This utility model embodiment does not impose specific limitations here.

[0049] like Figure 1 As shown, in one embodiment, the cross-sectional dimension of the fixing part 1 gradually decreases from the end furthest from the insertion part 2 toward the end closest to the insertion part 2. Here, the cross-sectional dimension of the fixing part 1 refers to the total cross-sectional area of ​​the fixing part 1, including the cross-sectional area of ​​the speaker mounting hole 11, and the minimum value of the cross-sectional dimension of the fixing part 1 is greater than the maximum value of the cross-sectional dimension of the insertion part 2. Since the cross-sectional dimension of the user's external auditory canal opening generally gradually decreases toward the inside of the ear canal, setting the cross-sectional dimension of the fixing part 1 to gradually decrease from the end furthest from the insertion part 2 toward the end closest to the insertion part 2 allows the shape of the fixing part 1 to better fit the structure of the user's external auditory canal opening, thereby allowing the outer surface of the fixing part 1 to better conform to the wall of the user's external auditory canal opening and avoiding feedback howling. Furthermore, the user can control the insertion depth of the fixing part 1 according to the size of their own external auditory canal opening to achieve a secure and comfortable fit, thereby further improving the adaptability of the earmold.

[0050] The fixing part 1 can be configured as a frustum shape. The frustum shape of the fixing part 1 is simple in structure, facilitating the production and processing of ear molds, and also allowing it to better fit ear canals of different structures and sizes. Furthermore, the smooth outer surface of the frustum shape of the fixing part 1 improves user comfort when wearing the ear mold. It should be noted that the frustum shape includes straight frustum and oblique frustum, and the outer surface of the fixing part 1 can be arched to further enhance user comfort when wearing the ear mold.

[0051] Of course, in other embodiments, the cross-sectional dimensions of the fixing part 1 can remain unchanged; for example, the fixing part 1 can be set as a cylinder.

[0052] like Figure 1 As shown, the outer surface of the fixing part 1 is smoothly connected to the outer surface of the insertion part 2, that is, the outer surface of the fixing part 1 and the outer surface of the insertion part 2 form a continuous and flat surface. In this way, the outer surface of the fixing part 1 and the insertion part 2 as a whole is smooth, thereby improving the comfort of the user when wearing the earmold.

[0053] like Figures 1 to 2 As shown, the earmold also includes a support part 3, which is connected to the end of the fixing part 1 away from the insertion part 2. The support part 3 is made of soft silicone. The support part 3 can abut against the user's auricle, providing support for the entire earmold and preventing the fixing part 1 from loosening or falling out of the ear canal, thereby improving the stability and comfort of the user when wearing the earmold. Furthermore, making the support part 3 a soft silicone part also gives it good extensibility and plasticity. When wearing the earmold, the user can adjust the shape of the support part 3 according to the distance between the external auditory canal opening and the auricle, as well as the shape of the auricle, so that the earmold can be adapted to different users, thereby improving the adaptability of the earmold.

[0054] like Figures 1 to 2 As shown, the support part 3 is provided with a weight reduction hole 31. The weight reduction hole 31 can reduce the overall weight of the earmold, further improving the user's comfort when wearing the earmold; in addition, the weight reduction hole 31 can also make it convenient for the user to pick up or put on the earmold, so as to facilitate the user's operation.

[0055] like Figures 1 to 2 As shown, in one embodiment, the support portion 3 is arc-shaped. The arc-shaped support portion 3 is more adaptable to the shape of the user's auricle, increasing the contact area between the support portion 3 and the user's auricle, thereby improving the support effect and comfort of the support portion 3. Both ends of the arc-shaped support portion 3 can be connected to the fixing portion 1 to form a weight-reducing hole 31 between the fixing portion 1 and the support portion 3, improving the stability and reliability of the connection between the support portion 3 and the fixing portion 1; alternatively, only one end of the arc-shaped support portion 3 may be connected to the fixing portion 1. Of course, in other embodiments, the support portion 3 can also be semi-circular, triangular, or other regular or irregular shapes, as long as the end of the support portion 3 away from the fixing portion 1 can contact the user's auricle to provide overall support for the earmold. This embodiment of the present invention does not impose specific limitations here.

[0056] like Figures 1 to 2As shown, in one embodiment, the fixing part 1, the insertion part 2, and the support part 3 are integrally formed. This facilitates the production and processing of the earmold, ensures the stability and reliability of the connection between the fixing part 1, the insertion part 2, and the support part 3, and improves the overall integrity and consistency of the earmold, thereby enhancing its aesthetics and wearing comfort. Of course, in other embodiments, the fixing part 1, the insertion part 2, and the support part 3 can also be separate structures, and can be fixedly connected by other methods such as adhesive bonding or pressing. This embodiment of the present invention does not impose specific limitations here.

[0057] This embodiment of the invention also provides a hearing aid, including the aforementioned earmold. The hearing aid's speaker is installed within the speaker mounting hole 11. When the user wears the earmold, the sound emitted by the speaker can be guided into the user's ear canal through the sound transmission hole 21. The hearing aid uses the aforementioned soft silicone earmold, which is suitable for different users and allows users to fix speakers of different shapes and sizes, thereby reducing the cost of the hearing aid. Of course, in other embodiments, the earmold can also be used for cochlear implants, headphones, and other hearing aids; this embodiment of the invention does not impose specific limitations here.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
