[0058] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0059] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "rear," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] The inventors discovered that the main body of behind-the-ear (BTE) hearing aids is quite prominent and has a strong professional appearance, making it easy for others to distinguish between regular headphones and hearing aids. This may bother some users who value discreetness, affecting their psychological well-being. Furthermore, the wearing method of BTE hearing aids may restrict certain activities to some extent. For example, users who wear glasses may find interference between the BTE hearing aid and their glasses temples, causing inconvenience. Due to the larger size of the BTE hearing aid, there is a greater risk of displacement or falling during vigorous movements, further hindering the wearer's mobility.

[0062] In addition, because behind-the-ear hearing aids are relatively large and are worn between the back of the ear and the head, users may experience strong pressure or stuffiness behind the ear when wearing them for a long time, especially the part behind the ear that comes into contact with the head, which can easily cause discomfort.

[0063] Based on this, this utility model embodiment provides an ear clip-on hearing aid with an external receiver, see reference. Figures 1-9 As shown, it includes a receiver module 1, a main unit module 2, and an arc-shaped connector 3;

[0064] The host module 2 includes a main housing 21 and a PCBA board 22 housed within the main housing 21;

[0065] The arc-shaped connector 3 includes a flexible shell 31, a memory elastic element (not shown in the figure), and an electrical connector (not shown in the figure), wherein the flexible shell 31 encloses the memory elastic element and the electrical connector;

[0066] The flexible shell 31 is connected to the main shell 21 and the receiver module 1 respectively. The main shell 21 and the receiver module 1 can be clamped to the auricle under the elastic force of the memory elastic element.

[0067] The electrical connectors are respectively connected to the receiver module 1 and the PCBA board 22.

[0068] In an optional embodiment, the receiver module 1 includes a sub-housing 11, a sound-generating assembly 12, a flexible tube 14, and an earpiece 15. The sound-generating assembly 12 is disposed within the sub-housing 11. One end of the flexible tube 14 is connected to the sub-housing 11 and communicates with the sound-generating assembly 12, while the other end is connected to the earpiece 15. The sound emitted by the sound-generating assembly 12 can be transmitted to the user's ear canal through the flexible tube 14. The sub-housing 11 is connected to a flexible housing 31, and the sound-generating assembly 12 is electrically connected to the electrical connector.

[0069] In this embodiment of the utility model, reference is made to Figure 1As described in section 6, the host module 2 also includes a microphone assembly and a digital signal processor (not shown in the figure). The digital signal processor is electrically connected to the PCBA board 22, which is connected to the sound-generating assembly 12 via electrical connectors within the flexible housing 31, thus enabling the digital signal processor to be electrically connected to both the microphone assembly and the sound-generating assembly 12. The microphone assembly captures ambient sound signals and converts sound waves into electrical signals. These converted electrical signals are transmitted to the digital signal processor, where they are amplified and optimized to enhance sound intensity and optimize sound quality. The amplified electrical signals are then transmitted to the receiver, which converts them back into sound signals and transmits them directly to the user's ear canal, ensuring that the amplified sound can be clearly heard by the user. Furthermore, the digital signal processor is a chip integrated on the PCBA board, which can amplify and optimize the signal according to the user's hearing loss, thereby achieving on-demand enhancement of sound intensity.

[0070] The external receiver clip-on hearing aid provided in this embodiment abandons the traditional behind-the-ear hearing aid shape, separating the main unit module 2 and the receiver module 1 and connecting them via a flexible shell 31 and electrical connection. This represents a novel external receiver design. Compared to hearing aids with a built-in receiver, it reduces the probability of feedback whistling, resulting in a more stable and pure sound output, providing users with a more comfortable auditory experience. Furthermore, compared to traditional external receiver hearing aids, there is no need to wear the receiver first and then the hearing aid main unit, solving the problem of inconvenient operation and improving the ease, comfort, and stability of wearing. In addition, it also solves the problem of easily damaged wires in traditional external receiver hearing aids.

[0071] The external receiver ear clip-on hearing aid provided in this embodiment connects the main unit module 2 and the receiver module 1 via a flexible shell 31, achieving an ear clip wearing method. This reduces the professional appearance of the hearing aid, helps to reduce the attention of others to the hearing aid, and alleviates the psychological pressure on users who value discreetness. Furthermore, the secondary shell 11 can be accommodated in the concha cavity. Due to the clamping force on the auricle generated by the memory elastic element, the hearing aid can be securely clamped to the auricle. The flexible shell 31 provides flexible cushioning, reducing discomfort during clamping. Thus, while ensuring wearing stability, it improves comfort, reduces restrictions on user movement, and enhances the user experience. In particular, this external receiver ear clip-on hearing aid greatly facilitates people who need to wear glasses daily, solving the problem of inconvenience caused by interference between behind-the-ear hearing aids and the temples of glasses, and has high application value.

[0072] In an optional implementation, refer to Figures 1-4As shown, the main housing 21 includes a front housing 211 and a rear housing 212. The front housing 211 and rear housing 212 are fastened together, with the front housing 211 facing the secondary housing 11. When worn, the front housing 211 and secondary housing 11 fit snugly against the auricle, clamping it in place. The secondary housing 11 has an ellipsoidal external shape. The outer wall of the front housing 211 has a recess 2111 corresponding to the curvature of the secondary housing 11, and there is a clamping gap between the secondary housing 11 and the recess 2111. The front housing 211 and secondary housing 11 can be clamped against the auricle under the elastic force of the memory elastic element. The secondary housing 11 fits the concha cavity. Due to the recess 2111, the shape of the front housing 211 also fits more closely to the back of the ear, improving wearing stability and comfort.

[0073] In an optional implementation, refer to Figure 6 As shown, 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, thereby enabling the hearing aid to receive ambient sounds from different directions.

[0074] In an optional implementation, refer to Figure 3 and Figure 6 As shown, the upper part of the front shell 211 is provided with a first microphone mesh 25 corresponding to the position of the first microphone 241, and the lower part of the front shell 211 is provided with a second microphone mesh 26 corresponding to the position of the second microphone 242. The microphone port of the first microphone 241 is aligned with the first microphone mesh 25, and the microphone port of the second microphone 242 is aligned with the second microphone mesh 26. When worn, the back shell 212 is away from the back of the ear, and the front shell 211 is close to the back of the ear, with the first microphone mesh 25 facing upward and the second microphone mesh 26 facing downward, ensuring more comprehensive reception of ambient sounds and improving sound reception. Especially when users communicate with others, it can accommodate people of different heights and improve the accuracy of sound reception.

[0075] In an optional implementation, refer to Figure 1 , Figure 5 and Figure 6 As shown, the main unit module 2 also includes a battery 27 disposed within the main housing 21. The battery 27 is electrically connected to the PCBA board 22 and is used to power the hearing aid. The rear housing 212 is provided with charging contacts 28, which pass through the rear housing 212 and are electrically connected to the PCBA board 22. External power (by contacting the corresponding position inside the charging case) can be charged into the battery 27 through the charging contacts 28. The charging contacts 28 are located in a position on the rear housing 212 that will not come into contact with the skin, thereby preventing sweat from accumulating on the charging contacts 28 and causing corrosion.

[0076] In an optional embodiment, the host module 2 further includes a control button (not shown) and a button FPC (not shown). The button FPC is housed 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 which the control button is housed. The button FPC is electrically connected to the PCBA board 22 by means of soldering or crimping; 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. This change is transmitted to the corresponding circuit point on the PCBA board 22 through the button FPC. After detecting this change, the circuit system on the PCBA board 22 will perform the corresponding operation, such as increasing or decreasing the volume.

[0077] In an optional 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 can achieve wireless connection with other devices through the Bluetooth module.

[0078] In an optional implementation, refer to Figure 5 As shown, the host module 2 also includes a magnet 23 disposed in the main housing 21 for magnetic attraction with accessories such as the earphone box.

[0079] In an optional implementation, refer to Figures 8-9 As shown, the receiver module 1 also includes a quick-release connector 13. One end of the quick-release connector 13 is snapped into the sub-housing 11 and abuts against the sound-generating assembly 12, while the other end is inserted into a flexible tube 14. The end of the flexible tube 14 away from the quick-release connector 13 is inserted into the earpiece 15. The sound emitted by the sound-generating assembly 12 can be transmitted to the center of the earpiece 15 through the quick-release connector 13 and the flexible tube 14, thereby reaching the ear canal. By enclosing the sound-generating assembly 12 in the sub-housing 11, it is possible to eliminate the need for a wire connection to the main unit module 2, thus eliminating concerns about hearing aid malfunctions caused by wire wear.

[0080] In an optional implementation, refer to Figures 8-9 As shown, the sub-shell 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 within the outer shell 111. The limiting inner shell 112 partially encloses the sound-generating component 12 and is bonded to it. By partially enclosing and fixing the sound-generating component 12 with the limiting inner shell 112, and then placing the limiting inner shell 112 and the sound-generating component 12 together within the outer shell 111, sufficient space is ensured around the sound-generating component 12. This reduces physical contact between the sound-generating component 12 and other components, reduces vibration interference, reduces sound wave reflection and resonance, avoids sound distortion, ensures sound purity, and improves sound quality.

[0081] In an optional implementation, refer to Figures 8-9As shown, the limiting inner shell 112 is a semi-elliptical shell, and the outer shell 111 is a hollow ellipsoid, so 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 that the limiting inner shell 112 and the outer shell 111 are tightly connected, thereby ensuring the stability of the sub-shell 11 and the sound-generating component 12.

[0082] In an optional implementation, refer to Figures 8-10 As shown, the quick-release connector 13 includes a press connector 131 and a insertion tube 132. The press connector 131 is disposed on the outer periphery of the insertion tube 132, and the end of the press connector 131 near the sub-housing 11 is integrally connected to the end of the insertion tube 132 near the sub-housing 11. The press connector 131 can be pressed inward, that is, moved closer to the insertion tube 132, thereby reducing the outer diameter of the press connector 131, so that the press connector 131 can be smoothly inserted into the sub-housing 11. After being inserted into the sub-housing 11, the press is released, so that the press connector 131 can tightly abut against the inner wall of the sub-housing 11, thereby achieving a stable connection between the quick-release connector 13 and the sub-housing 11.

[0083] Furthermore, refer to Figures 8-10 As shown, the inner wall of the limiting inner shell 112 of the sub-shell 11 is provided with a recessed engaging portion 1121, and the outer wall of the pressing connector 131 is provided with a corresponding protrusion 1311. When the pressing connector 131 is pressed inward, it can be smoothly inserted into the sub-shell 11, and the protrusion 1311 is engaged with the engaging portion 1121. After the pressing is released, the protrusion 1311 and the engaging portion 1121 are tightly fitted, which strengthens the connection strength between the quick-release connector 13 and the sub-shell 11 and effectively prevents the quick-release connector 13 from coming out of the sub-shell 11.

[0084] In an optional implementation, refer to Figures 8-10 As shown, a pressing part 1312 is provided at the end of the pressing connector 131 away from the sub-housing 11. The end of the pressing part 1312 near the hose 14 is bent outward with the insertion tube 132 as the center, so that the pressing connector 131 can be brought closer to the insertion tube 132 by pressing the bent part. Furthermore, with the protrusion 1311 engaged with the engaging part 1121, the pressing part 1312 is located outside the sub-housing 11. If the quick-release connector 13 needs to be removed from the sub-housing 11, pressing the pressing part 1312 can separate the protrusion 1311 from the engaging part 1121, thereby quickly removing the quick-release connector 13 for easy cleaning.

[0085] In an optional implementation, refer to Figures 8-10As shown, a sealing plug 1321 is provided at the end of the connector 132 near the hose 14. The outer diameter of the sealing plug 1321 increases sequentially in the direction of the sub-housing 11. Specifically, the outer diameter of the end of the sealing plug 1321 furthest from the sub-housing 11 is smaller than the inner diameter of the hose 14, and its outer diameter increases sequentially along the direction of the sub-housing 11, with the outer diameter of the end closest to the sub-housing 11 being equal to or greater than the inner diameter of the hose 14. When connecting the connector 132 and the hose 14, the smaller inner diameter end of the sealing plug 1321 can be smoothly inserted into the hose 14, and after its larger inner diameter end is fully inserted into the hose 14, it fits the hose 14 with an interference fit, thereby ensuring a firm connection between the hose 14 and the quick-release connector 13, effectively preventing the hose 14 from separating from the quick-release connector 13 when the user wears it.

[0086] In an optional implementation, refer to Figures 8-9 As shown, the earplug 15 has a through hole 151 in the center. The end of the flexible tube 14 away from the sub-shell 11 is inserted into the through hole 151 and is press-fitted with the through hole 151 to achieve a tight connection between the flexible tube 14 and the earplug 15, preventing the flexible tube 14 from coming out of the earplug 15 and improving wearing stability.

[0087] In an optional implementation, refer to Figures 8-9 As shown, a limiting groove 152 is provided at the end of the through hole 151 away from the flexible tube 14. That is, when the earplug 15 is inserted into the concha cavity, the side close to the auricle is provided with a limiting groove 152 at the end of the through hole 151, and the end of the flexible tube 14 is inserted into the limiting groove 152, thereby preventing the flexible tube 14 from protruding from the through hole 151 and ensuring wearing safety.

[0088] In this embodiment, since the flexible tube 14 needs to cooperate with the limiting groove 152, the end of the flexible tube 14 connected to the earplug 15 is not easy to cut freely. However, the other end of the flexible tube 14 is sleeved on the insertion tube 132, and the connection stability is ensured by the interference fit with the sealing plug 1321. Therefore, the end of the flexible tube 14 sleeved on the insertion tube 132 can be cut freely. The cut flexible tube 14 will not affect the connection stability with the quick-release connector 13, thus allowing users to cut it according to their actual situation and meet their personalized needs.

[0089] In this embodiment of the invention, the flexible tube 14 and the secondary housing 11 are detachably connected via the quick-release connector 13. The earplug 15 is detachably connected via the flexible tube 14, thus connecting the sound-generating component 12 to the flexible tube 14 and effectively transmitting the sound from the sound-generating component 12 to the earplug 15. The quick-release connector 13 can be quickly detached from the secondary housing 11, and the flexible tube 14 can also be pulled out from the earplug 15 and the quick-release connector 13, providing users with greater freedom to replace or clean the flexible tube 14, which is beneficial to improving the user experience. Furthermore, the flexible tube 14 can be detached from the quick-release connector 13 and can be freely cut to adapt to different sizes and shapes of auricles, improving the comfort and stability of the hearing aid and meeting the personalized needs of users.

[0090] In an optional embodiment, the sound-generating component 12 is a moving iron unit, and the sound-generating port of the moving iron unit is aligned with the quick-release connector 13.

[0091] In an optional implementation, refer to Figure 7 and Figure 8 As shown, the main shell 21, the flexible shell 31, and the secondary shell 11 form a C-shaped structure. The main shell 21, the arc-shaped connector 3, and the secondary shell 11 together form a C-shaped structure. The shape-memory elastic element deforms under external force, facilitating wearing. When worn, the main shell 21 and the secondary shell 11 are close together, with the secondary shell 21 located inside the cochlea and the main shell 11 located behind the auricle. This makes the hearing aid compact, easy to wear, and less likely to fall out. To fit the auricle, the maximum thickness of both the main shell 21 and the secondary shell 11 is greater than the thickness of the flexible shell 31, making the hearing aid heavier at the sides and lighter in the middle, facilitating wearing.

[0092] In optional embodiments, the flexible shell 31, the main shell 21 and the secondary shell 11 are made of materials including but not limited to TPU soft rubber, silicone, etc.

[0093] In one specific embodiment, the memory elastic element can be made of nickel-titanium memory steel wire, which has good elasticity and thermal stability, ensuring that the memory elastic element can provide sufficient elastic force.

[0094] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. This disclosure is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
