The term "and / or" used in the present application includes any and all combinations of one or more of the associated listed items.

[0027] Please refer to Figures 1 to 3 An embodiment of the present application provides a hearing device, which comprises a package shell 10, a sound tube 20, and an acoustic component 30. The package shell 10 is provided with an assembly cavity 101, the acoustic component 30 is arranged in the assembly cavity 101, and the acoustic component 30 comprises a receiver 31 and a microphone 32. The sound tube 20 is connected to the package shell 10 and is provided with a first channel 21 and a second channel 22, the first channel 21 and the second channel 22 are arranged in a spaced manner and do not interfere with each other, one of the two corresponds to the receiver 31, and the other corresponds to the microphone 32.

[0028] In the related art, the hearing device is mostly used in cooperation with a hearing aid. The hearing device is worn in the ear canal of a user. A microphone on the hearing aid collects external sound, which is amplified by the hearing aid. The amplified electrical signal is converted into a sound signal by a receiver in the hearing device, which is transmitted to the ear canal of the user. In addition, the sound signal in the ear canal is received by the microphone of the hearing device and fed back to the hearing aid, which detects and processes the feedback signal. Therefore, due to the need to extend the hearing device into the ear canal of the user, the corresponding sound tube has a small size, which is very inconvenient when manufacturing a channel for sound signal transmission. Therefore, most sound tubes of the hearing device only have one channel, which leads to the fact that the signal received by the microphone in the hearing device is not completely from the sound in the ear canal, but also partly from the sound directly emitted by the receiver. Therefore, during processing and analysis, there is often interference, resulting in unclear and inaccurate sound signal transmission.

[0029] To this end, as shown in Figures 1 to 3 , the hearing device provided by the embodiment has a first channel 21 and a second channel 22 arranged at intervals in a sound tube 20. One of a microphone 32 and a receiver 31 is arranged corresponding to the first channel 21, and the other is arranged corresponding to the second channel 22. That is, the first channel 21 and the second channel 22 are respectively used as a sound channel of the microphone 32 and a sound channel of the receiver 31, so as to ensure that the microphone 32 and the receiver 31 have independent receiving channels and transmission channels. Therefore, such an arrangement is equivalent to isolating the sound channels of the microphone 32 and the receiver 31, so as to ensure that the sound signal acquisition of the microphone 32 is not affected by the receiver 31. This is conducive to the microphone 32 to clearly and accurately feed back the sound signal to the hearing aid, reduce the interference of the feedback sound signal, and is conducive to the hearing aid to correctly detect the sound fed back by the microphone 32 in the hearing device, thereby improving the detection accuracy and processing accuracy.

[0030] It is worth noting that the first channel 21 and the second channel 22 are not connected to each other, which means that the areas in the two channels are not connected, and the areas outside the channels are not included.

[0031] In actual use, an earplug is sleeved outside the sound tube 20 to improve the comfort and stability of wearing. A limiting protrusion 23 can be provided on the end of the sound tube 20 away from the packaging shell 10 to axially limit the assembly of the earplug, so as to avoid the earplug from being easily detached.

[0032] As shown in Figure 1 and Figure 2As shown, in some specific embodiments, the first channel 21 and the second channel 22 are arranged at intervals along a first direction, which is at an angle to the central axis of the sound tube 20. The length extension direction of the first channel 21 and the length extension direction of the second channel 22 are substantially along the central axis of the sound tube 20. The microphone 32 is configured corresponding to the first channel 21, and the receiver 31 is configured corresponding to the second channel 22. Alternatively, the microphone 32 is configured corresponding to the second channel 22, and the receiver 31 is configured corresponding to the first channel 21.

[0033] The first channel 21 and the second channel 22 can be arranged in parallel or at an angle. As long as the microphone 32 and the receiver 31 each correspond to an independent audio channel.

[0034] Furthermore, any cross-section of the sound tube 20 can be circular, near-circular, square, or near-square, etc., and any cross-section of the first channel 21 and any cross-section of the second channel 22 can also be circular, near-circular, square, or near-square, etc. For example, if any cross-section of the first channel 21 and any cross-section of the second channel 22 are both circular, it ensures that the surface of each channel is smooth, which is more conducive to the transmission of sound signals; and, any cross-section of the sound tube 20 is circular, which is conducive to adapting to the user's ear canal, making it easier to wear and reducing discomfort. This is only an example for illustration.

[0035] It is worth noting that a near-circular shape is roughly circular, a shape that expands uniformly outwards from a center point. Its characteristic is that the boundary lines are arc-shaped, and the curvature of these arcs is equal. Near-circular shapes possess radial symmetry and rotational invariance. A near-square shape is roughly square; that is, not strictly a square or rectangle, but rather a shape that is square overall, roughly having two pairs of opposite sides, and rounded or chamfered corners. The edges of a near-square shape can include straight lines, arcs, curves, and other line types.

[0036] Alternatively, any cross-section of the first channel 21 can be semi-circular, and any cross-section of the second channel 22 can be circular. This is only for illustrative purposes.

[0037] like Figures 1 to 3 As shown, in an optional embodiment, both the first channel 21 and the second channel 22 are through holes extending along the central axis of the sound tube 20. This not only simplifies the structure but also facilitates manufacturing and reduces costs. Alternatively, one of the first channel 21 and the second channel 22 can be a through hole formed in the sound tube 20, and the other can be a hollow tubular structure passing through the sound tube 20; or both the first channel 21 and the second channel 22 can be hollow tubular structures passing through the sound tube 20. This arrangement facilitates adjustment of the corresponding dimensions of each channel. For example, the first channel 21 can be a through hole, and the second channel 22 can be formed as a hollow tubular structure. It is sufficient that it can meet the requirements of the microphone 32 for receiving sound signals and the receiver 31 for transmitting sound signals.

[0038] The aperture corresponding to the first channel 21 and the aperture corresponding to the second channel 22 can be the same or different.

[0039] Please refer to Figure 1 and Figure 2 As some examples, the packaging shell 10 includes a shell body 11 and a partition plate 12, the partition plate 12 is arranged in the shell body 11, and the assembly cavity 101 is divided into a first cavity 1011 and a second cavity 1012 through the partition plate 12. One of the receiver 31 and the microphone 32 is arranged in the first cavity 1011, and the other is arranged in the second cavity 1012. The first cavity 1011 is communicated with the first channel 21, and the second cavity 1012 is communicated with the second channel 22. That is, by arranging the partition plate 12 to isolate the receiver 31 and the microphone 32 in assembly, further reducing the interference between the receiver 31 and the microphone 32 in sound signal processing.

[0040] As can be seen from the above, the hearing device provided by the embodiment uses the arrangement of the first channel 21 and the second channel 22 to meet the sound channel isolation of the receiver 31 and the microphone 32; and cooperates with the arrangement of the partition plate 12 to meet the assembly isolation of the receiver 31 and the microphone 32. In this way, the sound signal processing interference between the two can be more effectively reduced, and the feedback sound signal of the microphone 32 can be more clear and reliable.

[0041] The partition plate 12 is provided to divide the assembly cavity 101 into the first cavity 1011 and the second cavity 1012 arranged in an upper and lower manner. The microphone 32 is installed in the first cavity 1011 and fixed with the packaging shell 10; and the receiver 31 is installed in the second cavity 1012 and fixed with the packaging shell 10. At this time, the microphone 32 and the receiver 31 are arranged in an upper and lower spaced manner. The first cavity 1011 and the second cavity 1012 can be sealed cavities that do not interfere with each other, so as to fully isolate the microphone 32 and the receiver 31. Alternatively, the microphone 32 and the receiver 31 can be arranged in a spaced manner along the central axis direction of the sound tube 20. At this time, the partition plate 12 can be at least two and spliced with each other to divide the first cavity 1011 and the second cavity 1012, and one of the two is arranged in an L shape. It mainly meets the assembly isolation of the receiver 31 and the microphone 32, which is only used as an example here.

[0042] For example, the first cavity 1011 is assembled with the microphone 32, and the second cavity 1012 is assembled with the receiver 31. The size of the first cavity 1011 is slightly larger than the size of the microphone 32, and the size of the second cavity 1012 is slightly larger than the size of the receiver 31, so as to ensure that the microphone 32 and the receiver 31 are smoothly inserted and assembled, and the connection reliability is ensured. When the microphone 32 and the receiver 31 are assembled in place, the two can be fixed by using the point gluing method with respect to the respective corresponding cavity walls, so as to improve the connection reliability and avoid shaking of the two. Alternatively, welding fixation or clamping cooperation can be used to achieve fastening. As long as the microphone 32 and the receiver 31 are assembled reliably and do not shake, it is acceptable.

[0043] Alternatively, the size of the first cavity 1011 and the size of the second cavity 1012 are both significantly larger than the size of the corresponding receiver 31 and the size of the microphone 32, so as to ensure that the receiver 31 and the microphone 32 are not in contact with the partition plate 12. Alternatively, one of the receiver 31 and the microphone 32 is in contact with the partition plate 12 and is connected, and the other is not in contact with the partition plate 12.

[0044] As shown in Figure 1 and Figure 2 , in actual use, the microphone 32 includes a microphone body 321 and a vibration isolation sleeve 322, and the vibration isolation sleeve 322 is sleeved outside the microphone body 321. By using the vibration isolation sleeve 322, the microphone body 321 can be further prevented from being interfered by the vibration generated by the receiver 31.

[0045] Please refer to Figures 1 to 4 , further, the acoustic component 30 is also connected with an ear tube connecting line 33, the ear tube connecting line 33 passes through the packaging shell and is connected with the microphone 32 and the receiver 31 respectively, so as to meet the signal transmission. The other end of the ear tube connecting line 33 is connected with other elements on the hearing aid, so as to realize the signal transmission. The ear tube connecting line 33 can be fixed by point gluing with the packaging shell, so as to not only ensure the connection reliability of the two, but also effectively ensure the good sealing performance of the connection.

[0046] As shown in Figure 1 , in some embodiments, the sound tube 20 is integrally formed with the packaging shell 10, for example, integrally injection molded, or integrally formed by using 3D printing technology. The integrally formed setting not only simplifies the manufacturing process, but also is beneficial to the structural integrity and the sealing performance.

[0047] As shown in Figure 2As shown, alternatively, the sound tube 20 and the packaging shell 10 can be formed separately and connected. For example, the sound tube 20 and the packaging shell 10 can be manufactured by injection molding respectively, and then the sound tube 20 is fixed with the packaging shell 10 by snap fitting. In the snap fitting, one of the packaging shell 10 and the sound tube 20 is provided with a clamping groove 51, and the other is provided with a clamping protrusion 52, the clamping protrusion 52 is inserted and clamped in the clamping groove 51. The size of the packaging shell 10 is larger than the size of the sound tube 20, the clamping protrusion 52 can be provided on the edge of one end of the packaging shell 10, the clamping groove 51 can be provided on the outer side wall of one end of the sound tube 20, the sound tube 20 is inserted into the packaging shell 10 and the clamping protrusion 52 is clamped in the clamping groove 51, so as to realize fastening. Alternatively, the clamping groove 51 can be provided on the end surface of the packaging shell 10 facing the sound tube 20, and the clamping protrusion 52 can be provided on the sound tube 20, so as to satisfy the snap fitting.

[0048] Alternatively, the sound tube 20 is formed by injection molding or machining, and the packaging shell 10 is formed by stamping, and then the two are welded or glued to be fixed. Here, only an example is given, which mainly satisfies the stable fixation of the sound tube 20 and the packaging shell 10.

[0049] As shown in Figure 2 and Figure 4 Further, the packaging shell 10 can also be formed separately. Specifically, the packaging shell 10 includes at least two packaging petals 111 adjacent along the circumference of the packaging shell 10, and each packaging petal 111 is fixed by bonding or welding. The partition plate 12 can also be fixed by welding or bonding with one of the packaging petals 111; alternatively, the partition plate 12 can be directly fixed by welding or bonding with the sound tube 20, and then placed between the at least two packaging petals 111.

[0050] Please refer to Figures 1 to 4 In actual use, the hearing device further includes a packaging back cover 40 connected to the packaging shell 10 and sealing one end of the assembly cavity 101 away from the sound tube 20. The packaging back cover 40 and the packaging shell 10 are provided, which is equivalent to the shell of the entire hearing device being provided separately, which is beneficial to the assembly of the receiver 31 and the microphone 32 relative to the packaging shell 10, and then the sealing is performed by the packaging back cover 40, so as to ensure the sealing requirement of the entire hearing device.

[0051] Further, the packaging back cover 40 is provided with a holding portion 402. Specifically, the part of the packaging back cover 40 outside the assembly cavity 101 is extended with a convex to serve as the holding portion 402, which is convenient for the user to hold the holding portion 402 to take, place, wear and the like of the hearing device. The holding portion 402 includes a cylindrical segment and a spherical convex connected to the end of the cylindrical segment, which is convenient for the user to hold and not easy to fall off. At the same time, the packaging back cover 40 is provided with a through hole 401, which is in communication with the assembly cavity 101. The aforementioned ear tube connecting line 33 passes through the through hole 401 and extends into the assembly cavity 101 to be connected with the receiver 31 and the microphone 32. The ear tube connecting line 33 includes a sleeve tube and a metal lead wire, and the sleeve tube is wrapped outside the metal lead wire. The metal lead wire is provided with a plurality of metal lead wires, which are respectively connected with the receiver 31 and the microphone 32 to realize signal transmission. The sleeve tube protects the metal lead wire and is glued and fixed and sealed with the hole wall of the through hole 401.

[0052] As shown in Figure 2 , wherein the packaging back cover 40 can also be snap-fitted with the packaging shell 10, and the snap-fitting manner is basically similar to the snap-fitting manner of the packaging shell 10 and the sound tube 20 as described above, which will not be described here.

[0053] As shown in Figure 1 , alternatively, the packaging back cover 40 and the packaging shell 10 can also be glued and fixed, i.e. glued and fixed.

[0054] Alternatively, the packaging back cover 40 and the packaging shell 10 can be welded and fixed, screwed and connected and the like. As long as it can realize the assembly of the packaging back cover 40 and the packaging shell 10.

[0055] It can be understood that by using the snap-fitting or screwing manner, the packaging back cover 40 can be conveniently disassembled relative to the packaging shell 10, and the internal microphone 32 or receiver 31 can be replaced in time when damaged. By using the gluing or welding manner, the sealing property of the connection can be improved, and the infiltration of external impurities or liquid can be avoided.

[0056] In some embodiments, the packaging back cover 40 and the sound tube 20 can be respectively snap-fitted with the packaging shell 10, or the packaging back cover 40 and the packaging shell 10 can be glued and fixed, and the sound tube 20 can be snap-fitted with the packaging shell 10. Alternatively, the sound tube 20 and the packaging shell 10 can be integrally formed, and the packaging back cover 40 and the packaging shell 10 can be glued and fixed. This is only an example.

[0057] In actual use, when the packaging shell 10 is integrally formed, the microphone 32 and the receiver 31 can be loaded from the rear end of the packaging shell 10, and then the packaging rear cover 40 is fixed with the packaging shell 10. When the packaging shell 10 is separately formed, taking the example that the packaging shell 10 includes two packaging petals 111, the microphone 32 and the receiver 31 can be loaded into one of the two packaging petals 111, and the baffle 12 is arranged between the two, and then the packaging rear cover 40 is fixed with the packaging shell 10 after the two packaging petals 111 are fixed. It is worth noting that the rear end of the packaging shell 10 refers to the end facing the packaging rear cover 40, and the front end of the packaging shell 10 refers to the end facing the sound tube 20.

[0058] Please refer to Figure 1 As another example, the side of the microphone 32 facing the sound tube 20 is provided with a first sealing member 61 to achieve waterproof and dustproof effects for the microphone 32. For example, the first sealing member 61 can be a waterproof sound-permeable film, which can ensure smooth transmission of sound signals while meeting waterproof and dustproof requirements.

[0059] As shown in Figure 2 Further, the side of the receiver 31 facing the sound tube 20 can also be provided with a first sealing member 61 to meet the waterproof and dustproof performance of the receiver 31. At this time, the receiver 31 and the microphone 32 are both provided with a first sealing member 61.

[0060] Further, a second sealing member is provided at the end of the sound tube 20 away from the packaging shell 10 to achieve waterproof and dustproof effects at the front end of the sound tube 20. In addition, the provision of the second sealing member can effectively prevent cerumen and the like in the ear canal from entering the first channel 21 or the second channel 22, thereby ensuring normal use of the hearing device. The second sealing member can be a dust screen or a cerumen baffle, and of course can also be a waterproof sound-permeable film.

[0061] As can be seen from the above, the second sealing member mainly plays a role in dustproof, cerumen-proof, and preventing larger particles and secretions in the ear canal, and the first sealing member 61 mainly plays a role in waterproofing and preventing gas particles and the like. Of course, when the second sealing member is not provided at the end of the sound tube 20 away from the packaging shell 10, the first sealing member 61 at the microphone 32 can have two layers, with the outer layer used for dustproof, cerumen-proof, and preventing larger particles, and the inner layer used for waterproofing and preventing gas particles and the like.

[0062] In actual use, since the receiver 31 is used to transmit sound signals to the ear canal, if a waterproof sound-permeable film is provided at the front end of the receiver 31, it may affect the frequency response amplitude of the sound signals. Therefore, as shown in Figure 1 In some specific embodiments, based on the provision of the second sealing member at the sound tube 20, no first sealing member 61 needs to be installed at the receiver 31, and only a first sealing member 61 is provided at the microphone 32.

[0063] As shown in Figure 1 , taking the microphone 32 provided with the first sealing member 61 and the sound tube 20 provided with the second sealing member as an example. The sound tube 20 is provided with an assembly surface at one end thereof facing the packaging shell 10, the first sealing member 61 is provided with adhesive on both sides thereof, one side of the first sealing member 61 is adhered to the assembly surface, and the other side is adhered and fixed to the microphone 32. At the same time, the sound tube 20 is recessed with an assembly groove 24 at the other end thereof away from the packaging shell 10, the second sealing member is embedded in the assembly groove 24, and the side of the second sealing member facing the packaging shell 10 is adhered to the groove wall of the assembly groove 24.

[0064] The aforementioned through holes corresponding to the first channel 21 and the second channel 22 respectively penetrate to the bottom wall of the assembly groove 24.

[0065] Alternatively, the front end edge of the packaging shell 10 can extend radially inward to form an assembly surface, and the first sealing member 61 can be adhered to the assembly surface of the packaging shell 10; and the front end edge of the packaging shell 10 can be recessed with a clamping groove 51 to be clamped and fixed with the sound tube 20.

[0066] As shown in Figure 1 , in actual use, the sound tube 20 is integrally formed with the packaging shell 10. The first sealing member 61 is adhered to the front end of the microphone 32, and then inserted into the corresponding first cavity 1011 as a whole, so that the first sealing member 61 is adhered and fixed to the assembly surface on the aforementioned sound tube 20, and is point-glued and sealed at the rear end of the microphone 32.
