[0065] The application will be further described in detail through specific embodiments combined with the drawings. In different embodiments, similar elements are associated with similar element reference signs. In the following embodiments, many details are described in order to make the application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification, in order to avoid the core part of the application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for those skilled in the art according to the description in the specification and general technical knowledge in the art.

[0066] In addition, features described in the specification, operations or characteristics can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially changed or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0067] The serial numbers of the components in the specification, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connection (coupling) unless otherwise specified.

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

[0069] The hearing assistance device repositions the microphone hole, which is relatively hidden, without blocking the normal sound collection of the microphone hole. The hearing assistance device sets the microphone hole in the inner recess structure, which is a relatively small structure, and the user's fingers cannot enter the inner recess structure, so that when the user (especially the elderly user) operates the key, even if the inner recess structure is touched, the hidden microphone hole will not be blocked, the microphone hole can maintain communication with the external atmosphere, avoid the howling caused by blocking the microphone hole, and thus improve the user experience.

[0070] When the microphone hole is blocked, a sealed cavity is formed at the microphone hole, and when the volume of the sealed cavity changes, the air pressure in the cavity also changes, causing the microphone diaphragm to fluctuate, thereby forming howling. In this embodiment, the position of the microphone hole is redesigned to avoid blocking the microphone hole and thus avoid howling.

[0071] Please refer to FIGS. 1-6, the hearing assistance device of the present embodiment mainly comprises a microphone 1, a processor 2, a loudspeaker 3 and a support 4.

[0072] The hearing assistance device can be a back-hanging structure, which can be worn on the user's head, part of which is located on the user's ear. The back-hanging hearing assistance device is more stable to wear, and will not fall off in the case of walking or exercise. In addition, the left and right parts of the back-hanging hearing assistance device are connected as an integrated structure, which is not easy to lose.

[0073] In other embodiments, the hearing assistance device can also be in an ear-hanging structure, and the hearing assistance device can be worn on the ear of the user. The hearing assistance device in the ear-hanging structure can be designed as a single-ear structure or a double-ear structure, that is, the user can choose to wear the hearing assistance device on one of the left and right ears, or can choose to wear the hearing assistance device on both the left and right ears.

[0074] In this embodiment, the support 4 includes a rear hanging part 401, an ear hanging part 402, a first mounting part 403, and a second mounting part 404. The support 4 includes one rear hanging part 401, and two ear hanging parts 402, first mounting parts 403, and second mounting parts 404. The two ends of the rear hanging part 401 are respectively connected to one first mounting part 403, and the first mounting part 403 is connected to the second mounting part 404 through an ear hanging part 402, that is, the second mounting part 404, the ear hanging part 402, the first mounting part 403, the rear hanging part 401, the first mounting part 403, the ear hanging part 402, and the second mounting part 404 are sequentially connected, and the ear hanging part 402, the first mounting part 403, and the second mounting part 404 connected to the two ends of the rear hanging part 401 can be symmetrically arranged. The rear hanging part 401 is an arc-shaped structure adapted to the human head, and is used to be worn on the rear side of the head of the user (a hearing-impaired patient). The ear hanging part 402 is an arc-shaped structure adapted to the external auditory meatus, and is used to be worn on the upper end of the ear of the user. The first mounting part 403 is used to be worn on the position behind the upper end of the ear of the user. The second mounting part 404 is used to be worn on the ear canal opening of the user.

[0075] The first mounting part 403 and the second mounting part 404 are each provided with a receiving cavity, which can be used to mount components.

[0076] The microphone 1 is a sound receiver, which is configured to receive an initial sound signal and convert the initial sound signal into an electric signal. The microphone 1 is arranged in the support 4 and can be mounted in one or two first mounting parts 403 of the support 4.

[0077] The processor 2 is a control and processing device, which is in signal connection with the microphone 1, obtains the electric signal converted by the microphone 1, and is configured to process the electric signal and generate a control signal. The processor 2 is arranged in the support 4 and can be arranged in the first mounting part 403, or can be arranged in the second mounting part 404, the rear hanging part 401, or the ear hanging part 402.

[0078] The speaker 3 is an audio output device, which is in signal connection with the processor 2, is configured to convert the control signal into a hearing-aid sound signal, and transmits the hearing-aid sound signal to the user. The speaker 3 is arranged in the support 4 and is mounted in two second mounting parts 404. Part of the speaker 3 can be exposed from the second mounting part 404 to achieve a better playing effect.

[0079] The support 4 can also be provided with components such as a battery, which can be installed in one or more of the rear hanging part 401, the ear hanging part 402, the first mounting part 403, and the second mounting part 404, and can provide power for the hearing aid.

[0080] The outer surface of the support 4 is provided with a key 41, which is provided on the outer surface of the first mounting part 403 and is configured to input a control signal. The key 41 is in signal connection with the processor 2 and can include one or more of a volume adjustment key and a start-stop key. For example, the key 41 includes a first key and a second key, the first key is used to increase the playing volume of the loudspeaker 3, and the second key is used to decrease the playing volume of the loudspeaker 3. The key 41 protrudes from the outer surface of the first mounting part 403, and the user can operate the key 41 by pressing it with a finger.

[0081] The outer surface of the support 4 is also provided with a concave part 42, which is specifically provided on the outer surface of the first mounting part 403. The support 4 is also provided with a microphone hole 43, which is specifically provided on the first mounting part 403. The microphone hole 43 is a hole structure with two open ends, having opposite first and second openings 431 and 432. The first opening 431 of the microphone hole 43 is located in the concave part 42, and the second opening 432 of the microphone hole 43 is located on the inner surface of the first mounting part 403. The second opening 432 of the microphone hole 43 is in connection with the microphone 1, which is arranged in the first mounting part 403 and abuts the inner surface of the first mounting part 403, and the microphone 1 covers the second opening 432 in the first mounting part 403, so that the microphone 1 can communicate with the outside atmosphere through the microphone hole 43.

[0082] The first mounting part 403 can include a top surface 4a, a bottom surface 4b, an inner side surface 4c, and an outer side surface 4d. When the user wears the hearing aid, the top surface 4a faces upward, the bottom surface 4b faces downward, the inner side surface 4c faces the user, and the outer side surface 4d faces away from the user.

[0083] In this embodiment, the key 41 is arranged on the bottom surface 4b, which is convenient for the user to touch and press, and the key 41 is not easily touched by other objects, for example, when wearing a hat or lying on one's side, the key 41 will not be touched by mistake.

[0084] The concave part 42 is arranged on the bottom surface 4b, i.e., the microphone hole 43 is arranged at the lower end of the first mounting part 403. When worn, the first opening 431 of the microphone hole 43 faces downward, and dust and other foreign matter is not easy to enter the microphone hole 43, and rainwater or sweat is not easy to flow into the microphone hole 43, which can play a protective role in preventing dust and water.

[0085] When the user's finger is pressed into the inner recess 42, the finger is blocked by the inner recess 42 and cannot cover the first opening 431 of the microphone hole 43. The inner recess 42 forms a blocking protection for the first opening 431, avoiding the generation of howling caused by the finger covering the first opening 431.

[0086] In other embodiments, the inner recess 42 can also be arranged on other surfaces of the first mounting portion 403 except the inner side surface 4c, such as the top surface 4a or the outer side surface 4d. That is, the microphone hole 43 can be arranged on other surfaces of the first mounting portion 403 except the inner side surface 4c, and the inner recess 42 can also play a role in blocking the user's touch from covering the first opening 431, thereby preventing howling.

[0087] In this embodiment, the inner recess 42 can be a groove structure with a U-shaped cross-section, and the inner recess 42 has a bottom wall 421 and a side wall 422. The first opening 431 of the microphone hole 43 is arranged on the bottom wall 421 of the inner recess 42, and the first opening 431 is arranged at the bottommost part of the inner recess 42. When the finger is accidentally pressed, even if part of the finger is squeezed into the inner recess 42, it cannot contact the first opening 431. In other words, the first opening 431 is arranged at the bottommost part of the inner recess 42, which has the best anti-blocking effect.

[0088] In other embodiments, the first opening 431 of the microphone hole 43 can also be arranged on the side wall 422 of the inner recess 42, such as being arranged on the side wall 422 of the inner recess 42 close to the bottom wall 421. When the user accidentally touches, it is also impossible to contact and cover the first opening 431, which can also play a role in preventing the first opening 431 from being blocked.

[0089] In other embodiments, the inner recess 42 can also be a groove structure with a V-shaped cross-section, and the inner recess 42 has two opposite inclined side walls 422. The first opening 431 of the microphone hole 43 can also be arranged on the side wall 422 of the inner recess 42, and the first opening 431 is located at the position close to the bottom of the side wall 422 of the inner recess 42. When the user accidentally touches, it is also impossible to contact and cover the first opening 431, which can also play a role in preventing the first opening 431 from being blocked.

[0090] In this embodiment, the inner recess 42 is a strip-shaped groove, and the strip-shaped groove has a sufficient length, such as a length of more than 5 mm, for example, the length of the inner recess 42 is 10 mm. When the user's finger accidentally presses on the opening of the inner recess 42, one end or both ends of the strip-shaped inner recess 42 are not covered by the finger, that is, the user's finger cannot completely block the opening of the inner recess 42, so that the first opening 431 in the inner recess 42 can always be in communication with the atmosphere, thereby avoiding the generation of howling.

[0091] In this embodiment, the inner recess 42 can be a linear strip-shaped groove, and the length direction of the strip-shaped groove is parallel to the inner-outer direction of the first mounting portion 403. In this way, the strip-shaped groove is more likely to extend to the edge position of the bottom surface 4b. The edge position of the bottom surface 4b is generally provided with a circular arc transition, so that the end of the inner recess 42 can extend to the edge circular arc transition of the bottom surface 4b. It is difficult for a user's finger to press the flat surface and the edge circular arc transition of the bottom surface 4b at the same time, which can ensure that the opening of the inner recess 42 is not completely blocked, and thus the first opening 431 can be prevented from being blocked.

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

[0093] Please refer to FIG. 10, the inner recess 42 is located at different surfaces, such as the connecting edge position of the bottom surface 4b and the inner side surface 4c is a circular arc transition surface, one part of the opening of the inner recess 42 located at the bottom surface 4b faces the first direction A, and the other part of the opening of the inner recess 42 located at the circular arc transition surface faces the second direction B, which is the direction of the end position opening of the inner recess 42. Please refer to FIG. 11, the inner recess 42 is located at different surfaces, such as the connecting edge position of the bottom surface 4b and the inner side surface 4c and the outer side surface 4d is a circular arc transition surface, one part of the opening of the inner recess 42 located at the circular arc transition surface between the bottom surface 4b and the outer side surface 4d faces the first direction A, which is the direction of the end position opening of the inner recess 42; the other part of the opening of the inner recess 42 located at the circular arc transition surface between the bottom surface 4b and the inner side surface 4c faces the second direction B, which is the direction of the other end position opening of the inner recess 42. The plane direction of the opening of the inner recess 42 is shown by the dashed line in FIG. 10, the first direction A and the second direction B are both the normal direction of the opening of the inner recess 42, and the included angle θ between the first direction A and the second direction B is greater than or equal to 60°, so that the length of the inner recess 42 is longer, and the normal angle of the inner recess 42 is larger. When a user's finger is accidentally touched, it is difficult to press the inner recess 42 located at different surfaces and having a certain angular span, and thus this design can better protect the first opening 431.

[0094] In other embodiments, one end of the inner recess 42 can also extend to the outer side surface 4d, and / or the other end of the inner recess 42 extends to the inner side surface 4c. Extending the end of the inner recess 42 to the outer side surface 4d and / or the inner side surface 4c can lengthen the inner recess 42 and place the inner recess 42 on different surfaces, and also make the angle between the normal directions of the two ends of the opening of the inner recess 42 greater than 60°, so that the user's fingers cannot cover the entire opening of the inner recess 42 at the same time, and also can prevent the first opening 431 from being blocked. Please refer to FIG. 10, preferably, the inner recess 42 extends to the inner side surface 4c, and the user's fingers are less likely to contact the inner recess 42 on the inner side surface 4c, which can provide better protection. Please refer to FIG. 11, more preferably, one end of the inner recess 42 extends to the outer side surface 4d, and the other end of the inner recess 42 extends to the inner side surface 4c, the inner recess 42 is longer, and the inner recess 42 spans three outer side surfaces at the same time, so that it is more difficult for the user to block the opening of the inner recess 42 at the same time, and the protection is the best.

[0095] In this embodiment, the first opening 431 is arranged at the bottom of the inner recess 42, and the first opening 431 and the opening of the inner recess 42 form the maximum spacing, so that it is more difficult for the user's fingers to contact and cover the first opening 431.

[0096] The position of the first opening 431 in the length direction of the strip-shaped groove can be set according to the sound collection requirements of the microphone hole 43, for example, the first opening 431 can be located in the middle of the length direction of the strip-shaped groove, that is, the microphone hole 43 is located in the middle of the first mounting portion 403, which facilitates the installation and layout of the microphone hole 43, and the probability of being mistakenly touched and blocked by the fingers is smaller.

[0097] In other embodiments, the first opening 431 is located in the inner recess 42, and the first opening 431 is arranged at a position offset to the outside of the symmetric surface between the outer side surface 4d and the inner side surface 4c, that is, the first opening 431 is arranged relatively close to the outside.

[0098] When the hearing aid is worn, the inner side 4c will vibrate and generate sound waves. The sound waves can not only be directly transmitted to the bottom surface 4b, but also be transmitted to the user's head and reflected to the bottom surface 4b. Therefore, in fact, the sound waves generated by the inner side 4c on the bottom surface 4b are the superposition of two sound waves. As a result, on the symmetry plane between the outer side 4d and the inner side 4c, the sound waves generated by the inner side 4c are slightly larger than the sound waves generated by the outer side 4d, which causes the vibration cancellation surface between the inner side 4c and the outer side 4d to be located on the symmetry plane between the inner side 4c and the outer side 4d, and the vibration cancellation surface is closer to the outer side 4d. Based on this analysis, the first opening 431 is arranged on the bottom surface 4b and is relatively close to the outer side of the symmetry plane, so that the double microphone 3 is located on the actual vibration cancellation surface between the inner side 4c and the outer side 4d, which can maximize the elimination of the interference of the vibration on the microphone 1.

[0099] In other embodiments, the length direction of the linear strip-shaped groove (inner recess 42) can also be parallel or inclined to the front-rear direction of the first mounting portion 403, and the front-rear direction of the first mounting portion 403 is greater than the inner-outer direction, so that the length of the strip-shaped groove can be relatively long, and the length of the strip-shaped groove is also elongated, which makes it difficult for the user's finger to completely cover the opening of the inner recess 42, and thus the first opening 431 can be avoided from being blocked.

[0100] In other embodiments, the inner recess 42 can also have other shapes, for example, referring to FIG. 7, the inner recess 42 is of a curved type; referring to FIG. 8, the inner recess 42 is of an X type; and referring to FIG. 9, the inner recess 42 is of a herringbone type. The inner recess 42 of other shapes can also have the effect of elongating the length of the inner recess 42, so that it is difficult for the user's finger to completely cover the opening of the inner recess 42, and thus the first opening 431 can be avoided from being blocked.

[0101] In the embodiment, in order to prevent the user's finger from contacting and blocking the first opening 431 in the inner recess 42, the inner recess 42 needs to be designed in a small size. The cross section of the U-shaped inner recess 42 mainly includes two dimensions, i.e., the width and the depth. When the width of the inner recess 42 is relatively large, the depth of the inner recess 42 also needs to be relatively large. When the width of the inner recess 42 is relatively large, the depth of the inner recess 42 needs to be large enough to prevent the user's finger from contacting the bottom of the inner recess 42. When the width of the inner recess 42 is relatively small, the depth of the inner recess 42 can be relatively small. When the width of the inner recess 42 is relatively small, the opening is small, and the user's finger cannot enter the inner recess 42. At this time, the depth of the inner recess 42 is relatively small, and the user's finger cannot contact the bottom of the inner recess 42. When the width of the inner recess 42 is relatively small, the depth of the inner recess 42 can be relatively small. In this way, the processing difficulty of the inner recess 42 can be reduced. Of course, when the width of the inner recess 42 is relatively small, the depth of the inner recess 42 can also be relatively large, which can also prevent the user's finger from blocking the first opening 431 in the inner recess 42.

[0102] In the embodiment, the width of the inner recess 42 is not greater than 2 mm, and the width of the inner recess 42 can be 1-2 mm. The depth of the inner recess 42 is not less than 0.5 mm, and the depth of the inner recess 42 can be 0.5-1.5 mm, to prevent the user's finger from entering the inner recess 42 and blocking the first opening 431. More preferably, when the width of the inner recess 42 is 1-1.5 mm, the depth of the inner recess 42 is 0.5-1 mm. The depth of the inner recess 42 is selected to be relatively small, which can better ensure the sound collection effect of the microphone 1. Alternatively, more preferably, when the width of the inner recess 42 is 1.5-2 mm, the depth of the inner recess 42 is 1-1.5 mm. The width of the inner recess 42 is selected to be relatively large, which can facilitate the installation of the microphone 1 at the corresponding position. At the same time, when the width and the depth of the inner recess 42 are selected, the depth and the width of the inner recess 42 need to be adjusted at the same time. For example, when the width of the inner recess 42 is relatively large, the depth of the inner recess 42 needs to be further increased, which can reduce the probability of blocking the first opening 431.

[0103] In the embodiment, the outer surface of the support 4 is provided with the inner recess 42, and the first opening 431 of the microphone hole 43 is located in the inner recess 42. The microphone hole 43 is formed in a sunken hidden manner, and the inner recess 42 forms a convex blocking structure relative to the microphone hole 43. When the user touches the control button, the user can only touch the outer edge of the inner recess 42 and cannot contact the microphone hole 43 in the inner recess 42. That is, when the user touches the button, the user cannot block the microphone hole 43, which can avoid the howling caused by blocking the microphone hole 43 and improve the user experience.

[0104] In this embodiment, no other additional blocking structure is arranged at the opening of the inner recess 42, so that the sound collection of the first opening 431 of the microphone hole 43 is not blocked, and the sound collection effect of the microphone 1 is ensured.

[0105] Referring to FIGS. 12 and 13, in an embodiment, a hearing assistance device is provided, which is different from the hearing assistance device of any of the above embodiments in that a blocking structure 423 is added.

[0106] In this embodiment, the support 4 is provided with the blocking structure 423, which can be arranged at the opening in the inner recess 42. The blocking structure 423 is arranged above the first opening 431, and blocks the first opening 431 of the microphone hole 43. The blocking structure 423 is not in contact with the first opening 431, but is arranged in a spaced manner therefrom, and has a gap therebetween, which allows the microphone hole 43 to be in communication with the external atmosphere.

[0107] The blocking structure 423 further protects the first opening 431, and directly blocks the first opening 431, so that the user's fingers cannot contact the first opening 431.

[0108] When the support 4 is provided with the blocking structure 423, the inner recess 42 can not need to be arranged to be narrow or deep, but can be arranged to be wider and shallower, for example, the width of the inner recess 42 can be greater than 2 mm, and the depth can be less than 0.5 mm. On the basis of the physical blocking of the blocking structure 423, the inner recess 42 is arranged to be wider and shallower, and the user's fingers also cannot contact the first opening 431 of the microphone hole 43. Of course, when the inner recess 42 is provided with the blocking structure 423, the inner recess 42 can also be arranged to be narrow and deep, so as to have 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, and in the direction perpendicular to the plane, the projection of the blocking structure 423 covers the entire first opening 431, i.e., the first opening 431 is completely hidden below the blocking structure 423, so that the user's fingers cannot contact and cover the first opening 431, and a good blocking effect can be achieved. Of course, the bottom surface 4b of the first mounting portion 403 can also be a curved surface. At this time, in the direction directly opposite the microphone hole 1, the projection of the blocking structure 423 covers the entire first opening 431, and also has a blocking effect.

[0110] In other embodiments, the projection of the barrier structure 423 covers part of the first opening 431, i.e. part of the first opening 431 is hidden under the barrier structure 423, and other part of the first opening 431 is exposed relative to the barrier structure 423. The barrier structure 423 can still play a barrier role, so that the user's finger cannot contact and cover the first opening 431. Even if the user's finger can contact the exposed part of the first opening 431, it cannot contact the part of the first opening 431 covered by the barrier structure 423. The first opening 431 cannot be completely covered and blocked, so the projection of the barrier structure 423 covering part of the first opening 431 can also play a blocking role.

[0111] In the embodiment, the barrier structure 423 can be a barrier plate, and the barrier structure 423 can also be a barrier net or a barrier strip. The barrier net and the barrier plate can play a surface barrier role and have a certain barrier area, which can be greater than the area of the first opening 431 to achieve complete barrier coverage of the first opening 431. The barrier strip can be provided with a plurality of barrier strips arranged side by side, which can also play the same surface barrier role as the barrier plate.

[0112] In the embodiment, the upper surface of the barrier structure 423 can be flush with the bottom surface 4b of the first mounting portion 403, i.e. the barrier structure 423 does not protrude from the bottom surface 4b, and the user will not feel the existence of the barrier structure 423 when mis-touching. In other words, the protruding barrier structure 423 will give the user a bad user experience.

[0113] In other embodiments, part or all of the barrier structure 423 can also protrude from the bottom surface 4b, and the upper surface of the barrier structure 423 is provided as an arc-shaped structure such as a spherical surface. When the user mis-touches, no corner contact is formed, and the user experience can be improved.

[0114] Please refer to FIG. 14. In an embodiment, a hearing assistance device is provided. The hearing assistance device is different from the hearing assistance device of any of the above embodiments in that a plurality of key bosses 45 are provided, and the area between the key bosses 45 forms a concave portion 42.

[0115] In the embodiment, the outer surface of the support 4 is provided with a plurality of key bosses 45, such as the bottom surface 4b of the first mounting portion 403. One or more keys 41 are provided on each key boss 45. Any two key bosses 45 in the plurality of key bosses 45 are close to each other and have a small gap, and the small gap forms the concave portion 42.

[0116] The bottom wall 421 of the inner recess 42 is the bottom surface 4b, and the side wall 422 of the inner recess 42 is the side surface of the key boss 45. When the first opening 431 is located at the bottom wall 421 of the inner recess 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 at the side wall 422 of the inner recess 42, it is equivalent to the first opening 431 being located on the side surface of the key boss 45.

[0117] In this embodiment, by arranging the two key bosses 45 close to each other, the inner recess 42 for blocking the user from contacting the first opening 431 can also be formed. When the user accidentally touches, the user will press on the key boss 45 and cannot touch the first opening 431 between the two key bosses 45, thereby preventing the howling caused by accidental touch.

[0118] Please refer to FIG. 15 and FIG. 16, in an embodiment, a hearing assistance device is provided, which is different from the hearing assistance device of any of the above embodiments in that a protruding portion 44 is provided instead of the inner recess 42, and the first opening 431 is located near the protruding portion 44.

[0119] In this embodiment, the first opening 431 can be directly arranged on any outer surface of the support 4, for example, the first opening 431 is arranged on the bottom surface 4b of the first mounting portion 403, and the protruding portion 44 is further arranged on the bottom surface 4b of the first mounting portion 403, and the protruding portion 44 has a small gap with the first opening 431, and at the same time, the protruding portion 44 has a certain height, so that the protruding portion 44 can block the user from touching and plugging the first opening 431.

[0120] The protruding portion 44 can be a structure integrally formed with the first mounting portion 403, or the protruding portion 44 can be fixed to the first mounting portion 403 by bonding, heat sealing or other methods.

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

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

[0123] When the height of the protrusion 44 and the distance between the protrusion 44 and the first opening 431 are selected, the height of the protrusion 44 and the distance between the corresponding protrusion 44 and the first opening 431 need to be adjusted at the same time, for example, when the height of the protrusion 44 is lower, the distance between the protrusion 44 and the first opening 431 needs to be further reduced, so as 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 set closer, so that the protrusion 44 can play a blocking role. 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 set wider, and the protrusion 44 can also play a blocking role.

[0125] In other embodiments, the outer surface of the support 4 is provided with one or more key bosses 45, a first opening 431 is provided beside one key boss 45, and the part of the key boss 45 close to the first opening 431 forms a protrusion 44. The key boss 45 has sufficient height, and the distance between the key boss 45 and the first opening 431 is small enough, which can also achieve the blocking of the user's fingers, thereby avoiding whistling.

[0126] Please refer to FIG. 17, in an embodiment, a hearing aid device is provided, which is different from the hearing aid device of any of the above embodiments in that: no inner recess 42 and protrusion 44 are provided, and the first opening 431 is located at both ends of the key 41 provided on the same surface of the support 4.

[0127] In this embodiment, the first opening 431 is located at both ends of the key 41 provided on the same surface of the support 4, which increases the distance between the first opening 431 and the key 41, so that when the user operates the key 41, even if the user accidentally touches the key 41, it is difficult to touch the first opening 431 far away from the key 41. By such arrangement, the probability of the user accidentally blocking the first opening 431 can be greatly reduced, that is, the probability of whistling caused by accidental touch can be reduced.

[0128] In the embodiment, the first opening 431 and the button 41 can be arranged at two ends of any face of the support 4, except the inner face which will be blocked by the user's head. For example, the first opening 431 and the button 41 are arranged at two ends of the bottom face 4b of the first mounting portion 403, the button 41 is located at the front end of the bottom face 4b, the first opening 431 is located at the rear end of the bottom face 4b, and the corresponding microphone hole 43 is located at the rear end of the first mounting portion 403.

[0129] The first mounting portion 403 has a strip-shaped structure, and the length in the front-rear direction is greater than the length in other directions, so that the first opening 431 and the button 41 are located at two ends of the bottom face 4b of the first mounting portion 403 in the front-rear direction, and have a large spacing, which can well protect the first opening 431, reduce the probability of the user accidentally touching the first opening 431, and further reduce the probability of generating howling due to accidental touch.

[0130] The above application of specific examples is used to illustrate the present application, which is only used to help understand the present application, and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
