[0057] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0058] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "far", "near", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0059] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0060] The inventor found that the main body of the behind-the-ear hearing aid is relatively obvious and has a strong professional sense, making it easy for others to distinguish between a conventional earphone and a hearing aid, which may cause trouble to some users who pay attention to wearing concealment and affect the wearer's psychological feeling. Moreover, the wearing method of the behind-the-ear hearing aid may limit the wearer's certain activities to a certain extent. For example, users wearing glasses will feel that there is interference between the behind-the-ear hearing aid and the temple of the glasses, resulting in inconvenient wearing; due to the relatively large main body of the behind-the-ear hearing aid, when performing some large-scale movements, the risk of displacement or dropping of the hearing aid is relatively large, resulting in inconvenient movement of the wearer.

[0061] In addition, since the main body of the behind-the-ear hearing aid is relatively large and is worn between the back of the ear and the head, users may experience a strong sense of ear-back compression or ear-back sweating when wearing it for a long time. In particular, the area where the back of the ear contacts the head is prone to discomfort.

[0062] Based on this, an embodiment of the present invention provides an ear-clip type hearing aid with an external receiver. Referring to Figures 1-9 as shown, it includes a receiver module 1, a main unit module 2, and an arc-shaped connecting member 3;

[0063] The main unit module 2 includes a main housing 21 and a PCBA board 22, a digital signal processor (not shown in the figure), and a microphone assembly accommodated in the main housing 21;

[0064] The PCBA board 22 is electrically connected to the microphone assembly and the digital signal processor respectively;

[0065] The receiver module 1 includes a sub-housing 11, a sound generating assembly 12, a hose 14, and an earplug 15;

[0066] The sound generating assembly 12 is arranged in the sub-housing 11;

[0067] One end of the hose 14 is connected to the sub-housing 11 and is aligned with the sound generating assembly 12, and the other end is connected to the earplug 15;

[0068] The arc-shaped connecting member 3 includes a flexible housing 31, a memory elastic member (not shown in the figure), and an electrical connecting member (not shown in the figure). The flexible housing 31 wraps the memory elastic member and the electrical connecting member;

[0069] The flexible housing 31 is connected to the main housing 21 and the sub-housing 11 respectively. The main housing 21 and the sub-housing 11 can clamp the auricle under the elastic force of the memory elastic member;

[0070] The electrical connecting member is connected to the sound generating assembly 12 and the PCBA board 22 respectively;

[0071] The digital signal processor is used to process the signal transmitted by the microphone assembly and transmit the processed signal to the sound generating assembly 12.

[0072] In the embodiments of the present invention, a microphone assembly and a digital signal processor are electrically connected to a PCBA board 22 respectively, and the PCBA board 22 is connected to a sound generating assembly 12 through an electrical connector within a flexible housing 31, thereby realizing the electrical connection between the digital signal processor and the microphone assembly and the sound generating assembly 12 respectively. The microphone assembly is used to capture surrounding sound signals and convert sound waves into electrical signals. The converted electrical signals are transmitted to the digital signal processor, where these electrical signals are optimized to enhance the sound intensity and optimize the sound quality. The processed electrical signals are transmitted to the receiver, which converts the electrical signals into sound signals again and directly transmits them to the user's ear canal, ensuring that the optimized sound can be clearly and naturally heard by the user.

[0073] Furthermore, the digital signal processor is a chip integrated on the PCBA board, which can amplify, reduce noise, and optimize signals according to preset algorithms and the user's hearing loss situation, so as to enhance the sound intensity and optimize the sound quality according to the user's needs.

[0074] The earclip-type hearing aid with an external receiver provided by the embodiments of the present invention abandons the shape of the traditional behind-the-ear hearing aid. Instead, the main unit module 2 and the receiver module 1 are separated and connected through a flexible housing 31 and electrical connection, which is a completely new form of an external receiver. Compared with a hearing aid with an internal receiver, it can reduce the probability of feedback whistling, making the sound output by the hearing aid more stable and pure, and the user can obtain a more comfortable auditory experience. Compared with the traditional external receiver hearing aid, there is no need to wear the receiver first and then the hearing aid main unit, solving the problem of inconvenient operation, improving the convenience, comfort, and stability of wearing. In addition, it also solves the problem that the wires of the traditional external receiver hearing aid are easily damaged.

[0075] The earclip-type hearing aid with an external receiver provided by the embodiments of the present invention realizes an earclip-type wearing method by connecting the main unit module 2 and the receiver module 1 through a flexible housing 31 respectively, reducing the professional feeling of the hearing aid, helping to reduce the attention of others to the hearing aid, and reducing the psychological pressure of users who pay attention to wearing concealment. Moreover, the sub-housing 11 can be accommodated in the concha cavity. Due to the clamping force on the auricle generated by the memory elastic member, the hearing aid can be firmly clamped on the auricle. The flexible housing 31 can provide flexible buffering to reduce the discomfort of clamping, thereby improving the comfort on the premise of ensuring wearing stability, reducing the restriction on the user's activities, and enhancing the user experience. In particular, this earclip-type hearing aid with an external receiver greatly facilitates people who need to wear glasses daily, solving the problem of inconvenient wearing caused by the mutual interference between the behind-the-ear hearing aid and the temple of the glasses, and has high popularization and application value.

[0076] In an alternative embodiment, refer to Figures 1-4As shown in the figure, the main housing 21 includes a front housing 211 and a rear housing 212. Among them, the front housing 211 is snap-connected to the rear housing 212. The front housing 211 faces the auxiliary housing 11. When worn, the front housing 211 and the auxiliary housing 11 are closely attached to the auricle and clamp the auricle. The external shape of the auxiliary housing 11 is an ellipsoid. A recess 2111 corresponding to the radian of the auxiliary housing 11 is provided on the outer side wall of the front housing 211. And there is a clamping distance between the auxiliary housing 11 and the recess 2111. The front housing 211 and the auxiliary housing 11 can clamp the auricle under the elastic force of the memory elastic member. The auxiliary housing 11 fits the concha. Due to the setting of the recess 2111, the shape of the front housing 211 also fits the back of the ear better, which can improve the wearing stability and comfort.

[0077] In an alternative embodiment, referring to Figure 6 As shown in the figure, the microphone assembly includes a first microphone 241 and a second microphone 242. The first microphone 241 is fixed to the upper part inside the front housing 211, and the second microphone 242 is fixed to the lower part inside the front housing 211, so that the hearing aid can receive ambient sounds from different directions.

[0078] In an alternative embodiment, referring to Figure 3 and Figure 6 As shown in the figure, a first microphone mesh 25 corresponding to the position of the first microphone 241 is provided on the upper part of the front housing 211, and a second microphone mesh 26 corresponding to the position of the second microphone 242 is provided on the lower part of the front housing 211. The sound receiving port of the first microphone 241 is aligned with the first microphone mesh 25, and the sound receiving port of the second microphone 242 is aligned with the second microphone mesh 26. When worn, the rear housing 212 faces away from the back of the ear, the front housing 211 is closely attached to the back of the ear, the first microphone mesh 25 faces upward, and the second microphone mesh 26 faces downward, ensuring that ambient sounds from the surrounding can be received more comprehensively, which is beneficial to optimizing the sound receiving effect. Especially when the user communicates with others, people of different heights can be taken into account, improving the accuracy of sound reception.

[0079] In an alternative embodiment, referring to Figure 1 、 Figure 5 and Figure 6 As shown in the figure, the main body module 2 further includes a battery 27 disposed inside the main housing 21. The battery 27 is electrically connected to the PCBA board 22 and is used to supply power to the hearing aid. The rear housing 212 is provided with a charging contact 28. The charging contact 28 passes through the rear housing 212 and is electrically connected to the PCBA board 22. Through the charging contact 28, external power (by abutting against the corresponding position inside the charging box) can be charged into the battery 27. The charging contact 28 is disposed at a position on the rear housing 212 that will not come into contact with the skin, thereby preventing sweat from accumulating on the charging contact 28 and causing corrosion.

[0080] In an alternative embodiment, the host module 2 further includes a control button (not shown in the figure) and a button FPC (not shown in the figure). The button FPC is received in the main housing 21 and electrically connected to the PCBA board 22. The rear housing 212 is provided with a button receiving hole (not shown in the figure), and the control button is received in the button receiving hole. The button FPC is electrically connected to the PCBA board 22 by means of soldering or crimping, etc.; the control button is electrically connected to the button FPC and thus electrically connected to the PCBA board 22. When the control button is pressed, a circuit change is triggered, and this change is transmitted to the corresponding circuit point on the PCBA board 22 through the button FPC. After the circuit system on the PCBA board 22 detects this change, corresponding operations will be performed, such as increasing the volume, decreasing the volume, etc.

[0081] In an alternative embodiment, the host module 2 further includes a Bluetooth module (not shown in the figure) disposed in the main housing 21. The Bluetooth module is electrically connected to the PCBA board 22, and wireless connection with other devices can be achieved through the Bluetooth module.

[0082] In an alternative embodiment, referring to Figure 5 As shown, the host module 2 further includes a magnet 23 disposed in the main housing 21 for magnetic attraction and cooperation with accessories such as an earphone case.

[0083] In an alternative embodiment, referring to Figures 8-9 As shown, the receiver module 1 further includes a quick-release connector 13. One end of the quick-release connector 13 is snap-connected to the sub-housing 11 and abuts against the sound generating component 12, and the other end is inserted into the hose 14. The end of the hose 14 remote from the quick-release connector 13 is inserted into the earplug 15. The sound emitted by the sound generating component 12 can be transmitted to the center of the earplug 15 through the quick-release connector 13 and the hose 14 and thus transmitted into the ear canal. By wrapping the sound generating component 12 with the sub-housing 11, it is possible to avoid connecting to the host module 2 through a wire, so there is no need to worry about hearing aid failures caused by wire wear.

[0084] In an alternative embodiment, referring to Figures 8-9 As shown, the sub-housing 11 includes an outer shell 111 and a limiting inner shell 112. The sound generating component 12 and the limiting inner shell 112 are disposed in the outer shell 111. The limiting inner shell 112 semi-wraps the sound generating component 12 and is bonded to the sound generating component 12. By semi-wrapping and fixing the sound generating component 12 with the limiting inner shell 112 and then disposing the limiting inner shell 112 and the sound generating component 12 together in the outer shell 111, sufficient space is ensured around the sound generating component 12, so that physical contact between the sound generating component 12 and other components can be reduced, vibration interference can be reduced, sound wave reflection and resonance can be reduced, sound distortion can be avoided, pure sound can be ensured, and the sound quality can be improved.

[0085] In an alternative embodiment, referring to Figures 8-9As shown, the limiting inner shell 112 is a semi-elliptical shell, and the outer shell 111 is a hollow ellipsoid, such that the outer side wall of the limiting inner shell 112 is in close contact with the inner side wall of the outer shell 111, ensuring the tight connection between the limiting inner shell 112 and the outer shell 111, thereby guaranteeing the stability of the secondary housing 11 and the sound generating assembly 12.

[0086] In an alternative embodiment, referring to Figures 8-10 As shown, the quick-release connector 13 includes a pressing joint 131 and an insertion tube 132. The pressing joint 131 is disposed on the outer periphery of the insertion tube 132, and one end of the pressing joint 131 close to the secondary housing 11 is integrally connected to one end of the insertion tube 132 close to the secondary housing 11. The pressing joint 131 can be pressed inward, that is, closer to the insertion tube 132, thereby reducing the outer diameter of the pressing joint 131, enabling the pressing joint 131 to be smoothly inserted into the secondary housing 11. After being inserted into the secondary housing 11 and the pressing is released, the pressing joint 131 can tightly abut against the inner wall of the secondary housing 11, thereby achieving the stable connection between the quick-release connector 13 and the secondary housing 11.

[0087] Furthermore, referring to Figures 8-10 As shown, a concave engaging portion 1121 is provided on the inner wall of the limiting inner shell 112 of the secondary housing 11, and a protruding portion 1311 is correspondingly provided on the outer wall of the pressing joint 131. When the pressing joint 131 is pressed inward, the pressing joint 131 can be smoothly inserted into the secondary housing 11, and the protruding portion 1311 is engaged with the engaging portion 1121. After the pressing is released, the protruding portion 1311 and the engaging portion 1121 are tightly fitted, strengthening the connection strength between the quick-release connector 13 and the secondary housing 11, effectively preventing the quick-release connector 13 from disengaging from the secondary housing 11.

[0088] In an alternative embodiment, referring to Figures 8-10 As shown, a pressing portion 1312 is provided at one end of the pressing joint 131 away from the secondary housing 11. One end of the pressing portion 1312 close to the hose 14 is bent outward with the insertion tube 132 as the center, thereby facilitating the pressing of the bent portion to make the pressing joint 131 closer to the insertion tube 132. Moreover, when the protruding portion 1311 is engaged with the engaging portion 1121, the pressing portion 1312 is located outside the secondary housing 11. If it is necessary to disassemble the quick-release connector 13 from the secondary housing 11, by pressing the pressing portion 1312, the protruding portion 1311 can be separated from the engaging portion 1121, thereby quickly removing the quick-release connector 13 for easy cleaning.

[0089] In an alternative embodiment, referring to Figures 8-10As shown, a sealing plug 1321 is provided at one end of the insertion pipe 132 close to the hose 14. The outer diameter of the sealing plug 1321 increases successively in the direction of the auxiliary housing 11. Specifically, the outer diameter of the end of the sealing plug 1321 away from the auxiliary housing 11 is smaller than the inner diameter of the hose 14, and its outer diameter increases successively in the direction of the auxiliary housing 11, and the outer diameter of its end closest to the auxiliary housing 11 is equal to or greater than the inner diameter of the hose 14. When docking the insertion pipe 132 with the hose 14, the end with the smaller inner diameter of the sealing plug 1321 can be smoothly inserted into the hose 14. After its end with the larger inner diameter completely enters the hose 14, it is in interference fit with the hose 14, thus ensuring a firm connection between the hose 14 and the quick-release connector 13 and effectively preventing the hose 14 from separating from the quick-release connector 13 when the user wears it.

[0090] In an alternative embodiment, referring to Figures 8-9 As shown, a through hole 151 is provided at the center of the earplug 15. One end of the hose 14 away from the auxiliary housing 11 is inserted into the through hole 151 and is in interference fit with the through hole 151, realizing a tight connection between the hose 14 and the earplug 15, preventing the hose 14 from coming out of the earplug 15, and improving the wearing stability.

[0091] In an alternative embodiment, referring to Figures 8-9 As shown, a limiting groove 152 is provided at one end of the through hole 151 away from the hose 14, that is, on the side of the through hole 151 close to the auricle when the earplug 15 is inserted into the concha cavity. The end of the hose 14 is clamped into the limiting groove 152, thus preventing the hose 14 from protruding from the through hole 151 and ensuring wearing safety.

[0092] In this embodiment, since the hose 14 needs to cooperate with the limiting groove 152, it is not convenient to freely cut the end of the hose 14 connected to the earplug 15. However, the other end of the hose 14 is sleeved on the insertion pipe 132, and the connection stability is ensured by interference fit with the sealing plug 1321. Therefore, the end of the hose 14 sleeved on the insertion pipe 132 can be freely cut, and the cut hose 14 will not affect the connection stability with the quick-release connector 13, thus facilitating the user to cut it according to their actual situation and meeting the personalized needs of the user.

[0093] In an embodiment of the present invention, the quick-release connector 13 is detachably connected to the hose 14 and the auxiliary housing 11 respectively. The hose 14 is detachably connected to the earplug 15, so that the sound generating component 12 is connected to the hose 14, thereby effectively transmitting the sound of the sound generating component 12 to the earplug 15. The quick-release connector 13 can be quickly detached from the auxiliary housing 11, and the hose 14 can also be pulled out from the earplug 15 and the quick-release connector 13, providing a greater degree of freedom for the user to replace or clean the hose 14, which is beneficial to improving the user experience. Moreover, the hose 14 can be detached from the quick-release connector 13 and can be freely cut to adapt to auricles of different sizes and shapes, improving the comfort and stability of wearing the hearing aid and meeting the personalized needs of users.

[0094] In an alternative embodiment, the sound generating component 12 is a balanced armature unit, and the sound outlet of the balanced armature unit is aligned with the quick-release connector 13.

[0095] In an alternative embodiment, referring to Figure 7 and Figure 8 As shown, the main housing 21, the flexible housing 31 and the auxiliary housing 11 form a C-shaped structure. The main housing 21, the arc-shaped connector 3 and the auxiliary housing 11 integrally form a C-shaped structure. The memory elastic member is deformed by an external force, which is convenient for wearing. When wearing, the main housing 21 and the auxiliary housing 11 approach each other. The auxiliary housing 21 is located inside the cochlea, and the main housing 11 is located behind the auricle, making the shape of the hearing aid small and convenient to wear and not easy to fall off. In order to adapt to the auricle, the maximum thicknesses of the main housing 21 and the auxiliary housing 11 are both greater than the thickness of the flexible housing 31, making the overall hearing aid heavier on both sides and lighter in the middle, which is convenient for wearing.

[0096] In an alternative embodiment, the materials of the flexible housing 31, the main housing 21 and the auxiliary housing 11 include but are not limited to TPU soft glue, silica gel, etc.

[0097] In a specific embodiment, the memory elastic member can be made of nickel-titanium memory wire, which has good elasticity and thermal stability, ensuring that the memory elastic member can provide sufficient elastic force.
