[0049] The inventors discovered that the receiver module of an externally mounted hearing aid is prone to damage. Specifically, the wire between the receiver module and the main unit is easily broken, especially at the ends where it connects to the moving iron and the main unit, where it is easily worn down and damaged. Furthermore, the wire between the receiver module and the main unit is not adjustable in length, preventing users from freely changing the wire to a suitable size based on ear size, ear canal depth, and outer ear contour. This negatively impacts the stability and comfort of wearing the hearing aid.

[0050] Based on this, the present invention provides a receiver module for a hearing aid and a hearing aid, which will be described in detail below through specific embodiments.

[0051] Example 1

[0052] This utility model embodiment provides a receiver module for a hearing aid that can be connected to the main body of the hearing aid, see reference. Figures 1-6 As shown, it includes an outer shell 1, a limiting inner shell 2, a sound-generating assembly 3, a quick-release fastener 4, a flexible tube 5, and an earplug 6;

[0053] The sound-generating component 3 and the limiting inner shell 2 are disposed inside the outer shell 1;

[0054] The limiting inner shell 2 partially encloses the sound-generating component 3 and is bonded to the sound-generating component 3;

[0055] One end of the quick-release fastener 4 can be detachably snapped into the limiting inner shell 2 and aligned with the sound outlet of the sound-generating component 3, while the other end can be detachably inserted into the flexible tube 5.

[0056] The end of the hose 5 away from the quick-release fastener 4 can be detachably inserted into the earplug 6.

[0057] In this embodiment, refer to Figures 3-6As shown, the quick-release fastener 4 faces the sound outlet of the sound-generating component 3, and the flexible tube 5 is sleeved on the quick-release fastener 4. The sound emitted by the sound-generating component 3 can be transmitted to the center of the earplug 6 through the quick-release fastener 4 and the flexible tube 5, thereby transmitting it into the ear canal. By setting the limiting inner shell 2 and the sound-generating component 3 together inside the outer shell 1, the receiver module can be placed outside the main body of the hearing aid without being connected to the main body by a wire. This eliminates concerns about hearing aid malfunctions caused by wire wear and reduces the risk of hearing aid damage.

[0058] In this embodiment, the sound-generating component 3 is partially wrapped and fixed by the limiting inner shell 2, and then the limiting inner shell 2 and the sound-generating component 3 are set together in the outer shell 1. This ensures that there is enough space around the sound-generating component 3, thereby reducing the physical contact between the sound-generating component 3 and other components, reducing vibration interference, reducing sound wave reflection and resonance, avoiding sound distortion, ensuring sound purity, and improving sound quality.

[0059] The receiver module of the hearing aid provided in this embodiment of the invention is detachably connected to the flexible tube 5 and the limiting inner shell 2 via a quick-release fastener 4. The earpiece 6 is detachably connected to the flexible tube 5, thus connecting the sound-generating component 3 to the flexible tube 5 and effectively transmitting the sound from the sound-generating component 3 to the earpiece 6. The quick-release fastener 4 can be quickly removed from the limiting inner shell 2, and the flexible tube 5 can also be pulled out from the earpiece 6 and the quick-release fastener 4, providing users with greater freedom to replace or clean the flexible tube 5, which improves the user experience. Furthermore, the flexible tube 5 can be detached from the quick-release fastener 4 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.

[0060] In an optional embodiment, the limiting inner shell 2 is a semi-elliptical shell and the outer shell 1 is a hollow ellipsoid, so that the outer side wall of the limiting inner shell 2 is in close contact with the inner side wall of the outer shell 1, ensuring that the limiting inner shell 2 and the outer shell 1 are tightly connected, thereby ensuring the stability of the sound-generating component 3.

[0061] In an optional implementation, refer to Figures 3-8 As shown, the quick-release fastener 4 includes a pressing connector 41 and a insertion tube 42. The pressing connector 41 is disposed on the outer periphery of the insertion tube 42, and the end of the pressing connector 41 near the limiting inner shell 2 is integrally connected to the end of the insertion tube 42 near the limiting inner shell 2. The pressing connector 41 can be pressed inward, that is, moved closer to the insertion tube 42, thereby reducing the outer diameter of the pressing connector 41, so that the pressing connector 41 can be smoothly inserted into the limiting inner shell 2. After being inserted into the limiting inner shell 2, the pressing is released, so that the pressing connector 41 can tightly abut against the inner wall of the limiting inner shell 2, thereby achieving a stable connection between the quick-release fastener 4 and the limiting inner shell 2.

[0062] Furthermore, refer to Figures 3-8As shown, the inner wall of the limiting inner shell 2 is provided with a recessed engaging portion 21, and the outer wall of the pressing connector 41 is provided with a corresponding protrusion 411. When the pressing connector 41 is pressed inward, it can be smoothly inserted into the limiting inner shell 2, and the protrusion 411 is engaged with the engaging portion 21. After the pressing is released, the protrusion 411 and the engaging portion 21 are tightly fitted, which strengthens the connection strength between the quick-release fastener 4 and the limiting inner shell 2, and effectively prevents the quick-release fastener 4 from coming out of the limiting inner shell 2.

[0063] In an optional implementation, refer to Figures 3-8 As shown, a pressing part 412 is provided at the end of the pressing connector 41 away from the limiting inner shell 2. The end of the pressing part 412 near the hose 5 is bent outward with the insertion tube 42 as the center, so that the pressing connector 41 can be brought closer to the insertion tube 42 by pressing the bent part. Furthermore, with the protrusion 411 engaged with the engaging part 21, the pressing part 412 is located outside the limiting inner shell 2. If the quick-release fastener 4 needs to be removed from the limiting inner shell 2, pressing the pressing part 412 can separate the protrusion 411 from the engaging part 21, thereby quickly removing the quick-release fastener 4 for easy cleaning.

[0064] In an optional implementation, refer to Figures 3-6 As shown, a sealing plug 421 is provided at the end of the connector 42 near the hose 5. The outer diameter of the sealing plug 421 increases sequentially in the direction of the inner limiting shell 2. Specifically, the outer diameter of the end of the sealing plug 421 furthest from the inner limiting shell 2 is smaller than the inner diameter of the hose 5, and its outer diameter increases sequentially along the direction of the inner limiting shell 2, with the outer diameter of the end closest to the inner limiting shell 2 being equal to or greater than the inner diameter of the hose 5. When the connector 42 and the hose 5 are connected, the smaller inner diameter end of the sealing plug 421 can be smoothly inserted into the hose 5, and after its larger inner diameter end is fully inserted into the hose 5, it fits the hose 5 with an interference fit, thereby ensuring a firm connection between the hose 5 and the quick-release fastener 4, and effectively preventing the hose 5 from separating from the quick-release fastener 4 when the user wears it.

[0065] In an optional implementation, refer to Figures 3-6 As shown, the earplug 6 has a through hole 61 in the center. The end of the flexible tube 5 away from the limiting inner shell 2 is inserted into the through hole 61 and is press-fitted with the through hole 61 to achieve a tight connection between the flexible tube 5 and the earplug 6, preventing the flexible tube 5 from coming out of the earplug 6 and improving the wearing stability.

[0066] In an optional implementation, refer to Figures 3-6 As shown, a limiting groove 62 is provided at the end of the through hole 61 away from the tube 5. That is, when the earplug 6 is inserted into the concha cavity, the side close to the auricle is provided with a limiting groove 62 at the end of the through hole 61, and the end of the tube 5 is inserted into the limiting groove 62, thereby preventing the tube 5 from protruding from the through hole 61 and ensuring wearing safety.

[0067] In this embodiment, since the flexible tube 5 needs to cooperate with the limiting groove 62, there are requirements for the shape of this end of the flexible tube 5. The end of the flexible tube 5 connected to the earplug 6 is not easy to cut freely. However, the other end of the flexible tube 5 is sleeved on the insertion tube 42, and the connection stability is ensured by the interference fit with the sealing plug 421. Therefore, the end of the flexible tube 5 sleeved on the insertion tube 42 can be cut freely. The cut flexible tube 5 will not affect the connection stability with the quick-release fastener 4, so it is convenient for users to cut it according to their actual situation and meet their personalized needs.

[0068] In an optional embodiment, the sound-generating component 3 is a moving iron unit, and the sound-generating port of the moving iron unit is aligned with the quick-release fastener 4.

[0069] In an optional implementation, the hose is made of PVC and is highly flexible, allowing it to be bent freely, thereby improving wearing comfort.

[0070] In an optional embodiment, the earplug 6 sleeve, i.e., the bowl-shaped structure where the earplug 6 contacts the ear canal, is provided with a pressure-reducing hole (not shown in the figure). The pressure-reducing hole can prevent the ear canal from being completely blocked by the earplug 6, causing excessive pressure in the ear canal, thereby protecting hearing and improving wearing comfort.

[0071] The receiver module of the hearing aid provided in this embodiment has an outer shell 1 that can be fixedly connected to the main body of the hearing aid. When the main body is worn behind the ear, the earplug 6 can be inserted into the ear canal. The sound emitted by the sound-generating component 3 is transmitted to the ear canal through the flexible tube 5, making the sound received by the user more stable.

[0072] The receiver module of the hearing aid provided in this embodiment of the utility model encloses the sound-generating component 3 and the sound-generating component 3 in the outer shell 1, allowing the receiver module to be externally mounted on the hearing aid main body. Compared to the traditional method where the receiver module is connected to the main body via a wire, there is no need to worry about hearing aid malfunctions caused by wire wear, reducing the risk of hearing aid damage. Compared to the method where the receiver is built into the hearing aid, it can effectively reduce the probability of feedback and improve the auditory experience of the hearing aid.

[0073] Example 2

[0074] Based on the same inventive concept, this utility model embodiment also provides a hearing aid, including the receiver module of the hearing aid described in Embodiment 1.

[0075] 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. Thus, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model is also intended to include these modifications and variations.
