[0065] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0066] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0067] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0068] In one embodiment, a hearing aid is provided, which may be a bone conduction hearing aid or an air conduction hearing aid.

[0069] This hearing aid features a redesigned microphone hole, placing it in a relatively concealed position without obstructing its normal sound pickup. The microphone hole is located within a concave structure, a relatively small structure that prevents users' fingers from entering. This ensures that even if users (especially elderly users) touch the concave structure while operating the buttons, the hidden microphone hole will not be blocked. The microphone hole remains open to the outside atmosphere, preventing feedback caused by blockage and thus improving the user experience.

[0070] When the microphone hole is blocked, a sealed cavity is formed at the microphone hole. When the volume of the sealed cavity changes, the air pressure inside the cavity also changes, causing fluctuations in the microphone diaphragm, thus creating a howling sound. In this embodiment, the position of the microphone hole has been redesigned to avoid blockage and thus prevent howling.

[0071] Please refer to Figures 1 to 6 The hearing aid device in this embodiment mainly includes a microphone 1, a processor 2, a speaker 3, and a support 4.

[0072] Hearing aids can be worn on the head, with one part located on the ear. The behind-the-ear design makes the hearing aid more stable and prevents it from falling off while walking or exercising. Furthermore, the two parts of the behind-the-ear hearing aid are connected as one unit, making it less likely to be lost.

[0073] In other embodiments, the hearing aid can also be an ear-hook structure, which can be worn on the user's ear. The ear-hook structure hearing aid can be designed as a single-ear structure or a binaural structure, that is, the user can choose to wear the hearing aid in one of the left or right ears, or choose to wear the hearing aid in both ears.

[0074] In this embodiment, the support member 4 includes a back hook portion 401, an ear hook portion 402, a first mounting portion 403, and a second mounting portion 404. Specifically, the support member 4 includes one back hook portion 401, two ear hook portions 402, a first mounting portion 403, and a second mounting portion 404. Each end of the back hook portion 401 is connected to a first mounting portion 403. The first mounting portion 403 is connected to the second mounting portion 404 via an ear hook portion 402. That is, the second mounting portion 404, ear hook portion 402, first mounting portion 403, back hook portion 401, first mounting portion 403, ear hook portion 402, and second mounting portion 404 are sequentially connected, and the ear hook portions 402, first mounting portions 403, and second mounting portions 404 connected to both ends of the back hook portion 401 can be symmetrically arranged. The back hook portion 401 is an arc-shaped structure adapted to the human head and is used to be worn on the back of the head of the user (hearing-impaired patient). The ear hook 402 is an arc-shaped structure that fits the outer ear. The ear hook 402 is used to wear on the upper part of the user's ear. The first mounting part 403 is used to wear on the back side of the upper part of the user's ear. The second mounting part 404 is used to wear on the opening of the user's ear canal.

[0075] Both the first mounting section 403 and the second mounting section 404 are provided with accommodating cavities, which can be used to mount components.

[0076] Microphone 1 is a sound receiving device, configured to receive an initial sound signal and convert it into an electrical signal. Microphone 1 is disposed within support member 4, and microphone 1 can be installed within one or both first mounting portions 403 of support member 4.

[0077] Processor 2 is a control and processing device. Processor 2 is connected to microphone 1 for signal transmission. Processor 2 acquires the electrical signals converted by microphone 1 and is configured to process the electrical signals and generate control signals. Processor 2 is disposed within support member 4. Processor 2 can be disposed within first mounting part 403, second mounting part 404, rear hanging part 401, or ear hook part 402.

[0078] Speaker 3 is an audio output device. Speaker 3 is connected to processor 2 via a signal. Speaker 3 is configured to convert control signals into hearing aid sound signals and transmit the hearing aid sound signals to the user. Speaker 3 is disposed within support member 4 and mounted within two second mounting portions 404. Part of speaker 3 can be exposed within the second mounting portions 404 for better playback effect.

[0079] The support member 4 may also contain components such as batteries. These components can be installed in one or more of the rear hanging part 401, ear hook part 402, first mounting part 403, and second mounting part 404. The battery can provide power to the hearing aid device.

[0080] The outer surface of the support member 4 is provided with a button 41. The button 41 is located on the outer surface of the first mounting part 403 and is configured to input control signals. The button 41 is signal-connected to the processor 2. The button 41 may include one or more of a volume adjustment button and a start / stop button. For example, the button 41 includes a first button and a second button. The first button is used to increase the playback volume of the speaker 3, and the second button is used to decrease the playback volume of the speaker 3. The button 41 protrudes from the outer surface of the first mounting part 403, and the user can operate the button 41 by pressing it with their finger.

[0081] The outer surface of the support member 4 is also provided with a recessed portion 42, which is specifically located on the outer surface of the first mounting portion 403. The support member 4 is also provided with a microphone hole 43, which is specifically located on the first mounting portion 403. The microphone hole 43 is a hole structure with openings at both ends. The microphone hole 43 has a first opening 431 and a second opening 432 opposite to each other. The first opening 431 of the microphone hole 43 is located inside the recessed portion 42, and the second opening 432 of the microphone hole 43 is located on the inner surface of the first mounting portion 403. The second opening 432 of the microphone hole 43 is connected to the microphone 1. The microphone 1 is disposed inside the first mounting portion 403 and abuts against the inner surface of the first mounting portion 403. The microphone 1 covers the second opening 432 inside the first mounting portion 403, so that the microphone 1 can communicate with the outside atmosphere through the microphone hole 43.

[0082] The first mounting part 403 may include a top surface 4a, a bottom surface 4b, an inner surface 4c, and an outer surface 4d. When the user wears the hearing aid, the top surface 4a faces upward, the bottom surface 4b faces downward, the inner surface 4c faces the user and is in contact with the user's head, and the outer surface 4d faces away from the user.

[0083] In this embodiment, button 41 is located on the bottom surface 4b. The button 41 is located on the bottom surface 4b, which makes it convenient for users to touch and press. Button 41 is also not easily touched by other objects. For example, when wearing a hat or lying on the side, button 41 will not be accidentally touched.

[0084] The recessed portion 42 is located on the bottom surface 4b, that is, the microphone hole 43 is located at the lower end of the first mounting portion 403. When worn, the first opening 431 of the microphone hole 43 faces downward, so dust and other foreign objects are not easy to enter the microphone hole 43, and rain or sweat is not easy to flow into the microphone hole 43, which can play a protective role against dust and water.

[0085] When a user presses their finger on the recessed portion 42, the finger will be blocked by the recessed portion 42, preventing the finger from covering and blocking the first opening 431 of the microphone hole 43. The recessed portion 42 forms a barrier to protect the first opening 431, preventing feedback caused by the finger covering and blocking the first opening 431.

[0086] In other embodiments, the recess 42 can also be provided on other surfaces of the first mounting portion 403 other than the inner side 4c, for example, the recess 42 can be provided on the top surface 4a or the outer side 4d. That is, the microphone hole 43 can be provided on other surfaces of the first mounting portion 403 other than the inner side 4c. The recess 42 can also block the user's touch and seal the first opening 431, thereby preventing howling.

[0087] In this embodiment, the recessed portion 42 can be a U-shaped groove structure, having a bottom wall 421 and a side wall 422. The first opening 431 of the microphone hole 43 is located on the bottom wall 421 of the recessed portion 42. Since the first opening 431 is located at the very bottom of the recessed portion 42, even if a finger is accidentally pressed, it cannot contact the first opening 431, even if part of the finger is squeezed into the recessed portion 42. In other words, the first opening 431 being located at the very bottom of the recessed portion 42 provides the best anti-blocking effect.

[0088] In other embodiments, the first opening 431 of the microphone hole 43 can also be provided on the side wall 422 of the recess 42. For example, the first opening 431 is provided on the side wall 422 of the recess 42 near the bottom wall 421. When the user accidentally touches it, the first opening 431 cannot be touched or covered, which can also prevent the first opening 431 from being blocked.

[0089] In other embodiments, the recess 42 may also be a groove structure with a V-shaped cross-section. The recess 42 has two relatively inclined sidewalls 422. The first opening 431 of the microphone hole 43 may also be provided on the sidewall 422 of the recess 42. The first opening 431 is located near the bottom of the sidewall 422 of the recess 42. When the user accidentally touches it, the first opening 431 cannot be touched or covered, which can also prevent the first opening 431 from being blocked.

[0090] In this embodiment, the recessed portion 42 is a strip-shaped groove with sufficient length, greater than 5mm, for example, the length of the recessed portion 42 is 10mm. When a user's finger accidentally presses on the opening of the recessed portion 42, one or both ends of the strip-shaped recessed portion 42 are not covered by the finger, that is, the user's finger cannot completely block the opening of the recessed portion 42, so that the first opening 431 inside the recessed portion 42 can always communicate with the atmosphere, thereby avoiding the generation of a whistling sound.

[0091] In this embodiment, the recessed portion 42 can be a straight strip groove, the length direction of which is parallel to the inward and outward directions of the first mounting portion 403. This design makes it easier for the strip groove to extend to the edge of the bottom surface 4b. The edge of the bottom surface 4b is generally designed with a rounded transition, so that the end of the recessed portion 42 can extend to the rounded edge of the bottom surface 4b. It is difficult for the user's finger to press the flat surface of the bottom surface 4b and the rounded edge at the same time, which can ensure that the opening of the recessed portion 42 is not completely blocked, thereby preventing the first opening 431 from being blocked.

[0092] One end of the recessed portion 42 extends to the edge connecting the bottom surface 4b and the outer surface 4d, and the other end of the recessed portion 42 extends to the edge connecting the bottom surface 4b and the inner surface 4c, so that both ends of the recessed portion 42 are exposed on the outside. Alternatively, one end of the recessed portion 42 is located on the bottom surface 4b, and the other end of the recessed portion 42 extends to the edge of one side of the bottom surface 4b.

[0093] Please refer to Figure 10 The recessed portion 42 is located on different surfaces. For example, the connection edge between the bottom surface 4b and the inner surface 4c is a circular arc transition surface. A portion of the opening of the recessed portion 42 on the bottom surface 4b faces a first direction A, while the other portion of the opening of the recessed portion 42 on the circular arc transition surface faces a second direction B. The second direction B is the direction of the opening at the end of the recessed portion 42. Please refer to... Figure 11 Please refer to Figure 11The recessed portion 42 is located on different surfaces. For example, the connection edge between the bottom surface 4b and the inner surface 4c and the outer surface 4d is a circular arc transition surface. A portion of the opening of the circular arc transition surface between the bottom surface 4b and the outer surface 4d of the recessed portion 42 faces a first direction A, which is the direction of the opening at one end of the recessed portion 42. The other portion of the opening of the circular arc transition surface between the bottom surface 4b and the inner surface 4c of the recessed portion 42 faces a second direction B, which is the direction of the opening at the other end of the recessed portion 42. The planar direction of the opening of the recessed portion 42 is as follows: Figure 10 As shown by the dashed lines, both the first direction A and the second direction B are normal directions perpendicular to the opening of the concave portion 42 and pointing outwards. The angle θ between the first direction A and the second direction B is greater than or equal to 60°, which makes the length of the concave portion 42 longer and the angle between the normals of the concave portion 42 larger. When the user accidentally touches it with their finger, it is difficult to press and cover the concave portion 42 located on different surfaces and with a certain angular span. This design can play a better protective role for the first opening 431.

[0094] In other embodiments, one end of the recess 42 may extend to the outer surface 4d, and / or the other end of the recess 42 may extend to the inner surface 4c. Extending the end of the recess 42 to the outer surface 4d and / or the inner surface 4c can lengthen the recess 42 and place the recess 42 on different surfaces, thus making the angle between the normal directions at both ends of the opening of the recess 42 greater than 60°, preventing the user's finger from simultaneously covering the entire opening of the recess 42, and also preventing blockage of the first opening 431. Please refer to... Figure 10 Preferably, the recessed portion 42 extends to the inner surface 4c, making it difficult for the user's fingers to contact the recessed portion 42 located on the inner surface 4c, thus providing better protection. Please refer to... Figure 11 More preferably, one end of the recess 42 extends to the outer surface 4d, and the other end of the recess 42 extends to the inner surface 4c. The recess 42 is longer and spans across three outer surfaces, making it more difficult for users to block the opening of the recess 42 at the same time, thus providing the best protection.

[0095] In this embodiment, the first opening 431 is located at the bottom of the concave portion 42, and the first opening 431 and the opening of the concave portion 42 form the maximum distance, making it more difficult for the user's fingers to touch and cover the first opening 431.

[0096] The position of the first opening 431 along the length of the strip can be set according to the sound pickup requirements of the microphone hole 43. For example, the first opening 431 can be located in the middle of the length of the strip, that is, the microphone hole 43 is located in the middle of the first mounting part 403, which facilitates the installation and layout of the microphone hole 43 and reduces the probability of it being accidentally blocked by a finger.

[0097] In other embodiments, the first opening 431 is located inside the recess 42, and the first opening 431 is positioned on the outer side of the symmetrical plane between the outer side 4d and the inner side 4c. The distance between the first opening 431 and the outer side 4d is less than the distance between the first opening 431 and the inner side 4c, that is, the first opening 431 is positioned relatively outward.

[0098] When the hearing aid is worn, the inner surface 4c vibrates and generates sound waves. These sound waves are transmitted directly to the bottom surface 4b and also to the user's head, reflecting back to the bottom surface 4b. Therefore, the sound waves generated by the inner surface 4c on the bottom surface 4b are actually the superposition of two sound waves. Consequently, on the symmetrical plane between the outer surface 4d and the inner surface 4c, the sound waves generated by the inner surface 4c are slightly larger than those generated by the outer surface 4d. This results in the vibration cancellation surface between the inner surface 4c and the outer surface 4d being located closer to the outer surface 4d on the symmetrical plane. Based on this analysis, the first opening 431 is positioned on the bottom surface 4b, slightly to the outside of the symmetrical plane. This positions the dual microphones 3 on the actual vibration cancellation surface between the inner surface 4c and the outer surface 4d, minimizing the interference of vibration on the microphones 1.

[0099] In other embodiments, the length direction of the straight strip groove (recessed portion 42) may also be parallel or inclined to the front-back direction of the first mounting portion 403. The front-back direction of the first mounting portion 403 is greater than the inside-outside direction, so that the length of the strip groove can be set to be relatively long. Extending the length of the strip groove also makes it difficult for the user's finger to completely cover the opening of the recessed portion 42, thereby preventing the first opening 431 from being blocked.

[0100] In other embodiments, the recess 42 may also be of other shapes, for example, please refer to Figure 7 The concave portion 42 is curved; please refer to... Figure 8 The concave portion 42 is X-shaped; please refer to... Figure 9 The concave portion 42 is herringbone shaped. Other shapes of concave portions 42 can also extend the length of the concave portion 42, making it difficult for the user's finger to completely cover the opening of the concave portion 42, thereby preventing the first opening 431 from being blocked.

[0101] In this embodiment, to prevent the user's finger from touching and blocking the first opening 431 within the recessed portion 42, the recessed portion 42 needs to be designed with a smaller size. The cross-section of the U-shaped recessed portion 42 mainly includes two dimensions: depth and width. The width and depth of the recessed portion 42 are interrelated. When the width of the recessed portion 42 is relatively large, the depth also needs to be correspondingly deep. When the recessed portion 42 is wide, sufficient depth must be ensured to prevent the user's finger from touching the bottom of the recessed portion 42. When the width of the recessed portion 42 is relatively small, the depth can be correspondingly shallower. When the recessed portion 42 is narrow, a smaller opening is formed, preventing the user's finger from entering the recessed portion 42. In this case, the depth of the recessed portion 42 is shallow, preventing the user's finger from touching the bottom of the recessed portion 42. Specifically, when the width of the recessed portion 42 is narrow, the depth can be relatively shallow, thus reducing the processing difficulty of the recessed portion 42. Of course, when the width of the concave portion 42 is narrow, the depth of the concave portion 42 can be set to be deeper, which can also prevent the user's finger from blocking the first opening 431 inside the concave portion 42.

[0102] In this embodiment, the width of the recessed portion 42 is no greater than 2mm, the width of the recessed portion 42 can be 1-2mm, the depth of the recessed portion 42 is no less than 0.5mm, and the depth of the recessed portion 42 can be 0.5-1.5mm, to prevent fingers from being inserted into the recessed portion 42 and blocking the first opening 431. More preferably, when the width of the recessed portion 42 is 1-1.5mm, the depth of the recessed portion 42 is 0.5-1mm. Choosing to set the depth of the recessed portion 42 to be shallower can better ensure the sound reception effect of the microphone 1; or more preferably, when the width of the recessed portion 42 is 1.5-2mm, the depth of the recessed portion 42 is 1-1.5mm. Choosing to set the width of the recessed portion 42 to be wider can facilitate the installation of the microphone 1 in the corresponding position. At the same time, when selecting the width and depth of the recess 42, the corresponding depth and width of the recess 42 need to be adjusted simultaneously. For example, when the width of the recess 42 is wider, the depth of the recess needs to be further increased, which can reduce the probability of the first opening 431 being blocked.

[0103] In this embodiment, since the outer surface of the support member 4 is provided with a recessed portion 42, the first opening 431 of the microphone hole 43 is located inside the recessed portion 42, and the microphone hole 43 forms a sunken hidden setting. The recessed portion 42 forms an outwardly convex partition structure relative to the microphone hole 43, so that when the user touches the control button, the user can only touch the outer edge of the recessed portion 42 and cannot touch the microphone hole 43 inside the recessed portion 42. That is, the user will not block the microphone hole 43 when accidentally touching the button, which can avoid the howling caused by blocking the microphone hole 43 and improve the user experience.

[0104] In this embodiment, no additional obstruction structure needs to be provided at the opening of the recessed portion 42, so that the sound reception of the first opening 431 of the microphone hole 43 is not blocked, which is beneficial to ensuring the sound reception effect of the microphone 1.

[0105] Please refer to Figure 12 and Figure 13 In one embodiment, a hearing aid device is provided. The difference between this hearing aid device and the hearing aid device of any of the above embodiments is that a partition structure 423 is added.

[0106] In this embodiment, the support member 4 is provided with a partition structure 423. The partition structure 423 can be located at the opening in the recess 42. The partition structure 423 is located above the first opening 431. The partition structure 423 blocks the first opening 431 of the microphone hole 43. The partition structure 423 does not contact the first opening 431. The partition structure 423 and the first opening 431 are spaced apart. There is a gap between the partition structure 423 and the first opening 431. This gap allows the microphone hole 43 to remain in communication with the outside atmosphere.

[0107] The partition structure 423 provides further protection for the first opening 431 and forms a direct physical barrier to the first opening 431, preventing the user's fingers from touching the first opening 431.

[0108] When the support member 4 is provided with a baffle structure 423, the recessed portion 42 does not need to be narrow or deep. It can be wider and shallower. For example, the width of the recessed portion 42 can be greater than 2mm and the depth can be less than 0.5mm. Based on the physical baffle structure 423, the recessed portion 42 is made wider and shallower, so that the user's fingers cannot touch the first opening 431 of the microphone hole 43. Of course, when the recessed portion 42 is provided with a baffle structure 423, the recessed portion 42 can also be made narrower and deeper, which can form a double protection effect and better prevent howling.

[0109] In this embodiment, the bottom surface 4b of the first mounting portion 403 is a plane. In the direction perpendicular to this plane, the projection of the barrier structure 423 completely covers the first opening 431, meaning the first opening 431 is completely hidden below the barrier structure 423. This prevents the user's fingers from touching or covering the first opening 431, thus providing a good barrier effect. Alternatively, the bottom surface 4b of the first mounting portion 403 can also be curved. In this case, in the direction directly opposite the microphone hole 1, the projection of the barrier structure 423 covers the entire first opening 431, also providing a barrier effect.

[0110] In other embodiments, the projection of the partition structure 423 covers a portion of the first opening 431, meaning that a portion of the first opening 431 is hidden below the partition structure 423, while the other portion of the first opening 431 is exposed relative to the partition structure 423. The partition structure 423 can still function as a barrier, preventing the user's fingers from touching and covering the first opening 431. Even if the user's fingers can touch the exposed portion of the first opening 431, they cannot touch the portion of the first opening 431 covered by the partition structure 423. The first opening 431 cannot be completely covered and blocked. Therefore, the projection of the partition structure 423 covering a portion of the first opening 431 can also serve as a barrier.

[0111] In this embodiment, the partition structure 423 can be a partition plate, a partition mesh, or a partition strip, etc. The partition mesh and partition plate can function as surface partitions, having a certain partition area, which can be larger than the area of ​​the first opening 431, to achieve complete air gap coverage of the first opening 431. Multiple partition strips can be provided, and multiple partition strips arranged side-by-side can also serve the same surface partition function as the partition plate.

[0112] In this embodiment, the upper surface of the partition structure 423 can be flush with the bottom surface 4b of the first mounting part 403, that is, the partition structure 423 does not protrude from the bottom surface 4b, and the user will not feel the presence of the partition structure 423 when accidentally touched. In other words, a protruding partition structure 423 would give the user a bad user experience.

[0113] In other embodiments, part or all of the partition structure 423 may protrude from the bottom surface 4b. The upper surface of the partition structure 423 may be set as a spherical or other arc-shaped structure so that when the user accidentally touches it, no sharp corner contact will be formed, which can also improve the user experience.

[0114] Please refer to Figure 14 In one embodiment, a hearing aid device is provided. The difference between this hearing aid device and the hearing aid device of any of the above embodiments is that it is provided with a plurality of button protrusions 45, and the area between the button protrusions 45 forms a concave portion 42.

[0115] In this embodiment, the outer surface of the support member 4 is provided with a plurality of button protrusions 45, such as the bottom surface 4b of the first mounting part 403, which is provided with a plurality of button protrusions 45, and one or more buttons 41 are provided on one button protrusion 45. Any two button protrusions 45 among the plurality of button protrusions 45 are close to each other and have a small gap, which forms a recess 42.

[0116] The bottom wall 421 of the recessed portion 42 is the bottom surface 4b, and the side wall 422 of the recessed portion 42 is the side surface of the button boss 45. When the first opening 431 is located on the bottom wall 421 of the recessed portion 42, it is equivalent to the first opening 431 being located on the upper surface of the bottom surface 4b; when the first opening 431 is located on the side wall 422 of the recessed portion 42, it is equivalent to the first opening 431 being located on the side surface of the button boss 45.

[0117] In this embodiment, by placing the two button protrusions 45 close to each other, a recessed portion 42 can be formed to block the user from contacting the first opening 431. When the user accidentally presses the button, the user will press on the button protrusion 45 and will not be able to contact the first opening 431 between the two button protrusions 45, thereby preventing the howling sound caused by accidental touch.

[0118] Please refer to Figure 15 and Figure 16 In one embodiment, a hearing aid device is provided. The difference between this hearing aid device and the hearing aid device of any of the above embodiments is that a protrusion 44 is provided instead of a concave portion 42, and a first opening 431 is located near the protrusion 44.

[0119] In this embodiment, the first opening 431 can be directly set on any outer surface of the support member 4. For example, the first opening 431 can be set on the bottom surface 4b of the first mounting part 403, and a protrusion 44 is also provided on the bottom surface 4b of the first mounting part 403. There is a small gap between the protrusion 44 and the first opening 431, and the protrusion 44 has a certain height so that the protrusion 44 can block the user from touching and sealing the first opening 431.

[0120] The protrusion 44 can be an integrally formed structure with the first mounting part 403, or the protrusion 44 can be fixed to the first mounting part 403 by means of bonding, heat sealing or other methods.

[0121] In the direction perpendicular to the bottom surface 4b, the protrusion 44 can be a straight line, a curved line, an L-shaped line, or a U-shaped structure. The first opening 431 is located on one side or in the middle of the protrusion 44. The protrusion 44 forms a barrier on one side of the first opening 431 or forms a semi-enclosed barrier on the first opening 431. This can prevent the user from accidentally blocking the first opening 431 and thus avoid howling.

[0122] In this embodiment, the height of the protrusion 44 is greater than 0.8 mm, and the minimum distance between the protrusion 44 and the edge of the first opening 431 is less than 0.4 mm, so as to prevent the finger from blocking the first opening 431.

[0123] When selecting the height of the protrusion 44 and the distance between the protrusion 44 and the first opening 431, it is necessary to adjust the height of the protrusion 44 and the corresponding distance between the protrusion 44 and the first opening 431 at the same time. For example, when the height of the protrusion 44 is lower, it is necessary to further reduce the distance between the protrusion 44 and the first opening 431 in order to reduce the probability of the first opening 431 being blocked.

[0124] For example, when the height of the protrusion 44 is 0.8 mm, the minimum distance between the protrusion 44 and the edge of the first opening 431 is 0.2 mm. When the protrusion 44 is set lower, the distance between the protrusion 44 and the first opening 431 needs to be closer so that the protrusion 44 can function as a barrier. When the height of the protrusion 44 is 1 mm, the minimum distance between the protrusion 44 and the edge of the first opening 431 can be 0.4 mm. When the protrusion 44 is set higher, the distance between the protrusion 44 and the first opening 431 can be relatively wider, and the protrusion 44 can also function as a barrier.

[0125] In other embodiments, the outer surface of the support member 4 is provided with one or more button protrusions 45, and a first opening 431 is provided next to one button protrusion 45. The portion of the button protrusion 45 near the first opening 431 forms a protrusion 44. The button protrusion 45 has sufficient height, and the gap between the button protrusion 45 and the first opening 431 is small enough to block the user's finger, thereby avoiding howling.

[0126] Please refer to Figure 17 In one embodiment, a hearing aid device is provided. The difference between this hearing aid device and the hearing aid device of any of the above embodiments is that: it does not have a concave portion 42 and a protruding portion 44, and the first opening 431 is located at both ends of the button 41 on the same surface of the support member 4.

[0127] In this embodiment, the first opening 431 is located at both ends of the button 41 on the same surface of the support member 4. This increases the distance between the first opening 431 and the button 41, so that even if the user accidentally touches the button 41, the touch will be near the button 41, making it less likely for the user to accidentally touch the first opening 431, which is farther away from the button 41. This design also greatly reduces the probability of the user accidentally blocking the first opening 431, thus reducing the probability of a howling sound caused by accidental touch.

[0128] In this embodiment, the first opening 431 and the button 41 can be located at either end of any surface of the support member 4, except for the inner surface that will be obscured by the user's head. For example, the first opening 431 and the button 41 can be located at either end of the bottom surface 4b of the first mounting part 403, with the button 41 located at the front end of the bottom surface 4b and the first opening 431 located at the rear end of the bottom surface 4b, and the corresponding microphone hole 43 located at the rear end of the first mounting part 403.

[0129] The first mounting part 403 is a long strip structure, and its length in the front-to-back direction is greater than its length in other directions. This makes the first opening 431 and the button 41 located at the two ends in the front-to-back direction of the bottom surface 4b of the first mounting part 403, with a large gap. This can play a good protective role for the first opening 431, reduce the probability of the user accidentally blocking the first opening 431, and thus reduce the probability of accidental touch causing a howling sound.

[0130] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
