[035] Based on the attached embodiments, the technical solutions in the embodiments of the present invention can be clearly and completely described as follows. Obviously, the embodiments described are only a part of the embodiments of the present invention rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art under the premise of no creative work are within the scope of protection of the present invention.

[036] In the present invention, an acoustic device may be a hearing aid, a listening bracelet, a headset, a loudspeaker, a pair of smart glasses, and other devices with acoustic output functions. In some embodiments, an acoustic device 1 may be a bone conduction hearing aid, a bone conduction hearing bracelet, a bone conduction headset, a bone conduction loudspeaker, a pair of bone conduction smart glasses, and other devices that implement acoustic output based on bone conduction. In the present invention, the acoustic device 1 as a bone conduction hearing aid may be taken as an example for illustration.

[037] A hearing aid is a small speaker that amplifies a sound that is originally inaudible, and then, with the residual hearing of the hearing-impaired person, the sound can be sent to a brain auditory center. However, due to damage or degeneration of the hearing of the hearing-impaired, the traditional method of transmission through the ear canal has a limited improvement in the hearing effect for the hearing-impaired. In some modalities, bone conduction technology can be applied to the hearing aid. Bone conduction technology can break the traditional method of sound transmission through the ear canal and effectively improve the hearing effect for the hearing-impaired, allowing the hearing-impaired to receive a clearer and more stable sound.

[038] Bone conduction hearing aids can convert audio into a mechanical vibration with different frequencies, using a human bone as a medium that transmits the mechanical vibration, and then transmitting the mechanical vibration to an auditory nerve, so that the user can receive sound without the use of an external auditory canal and tympanic membrane. In some modalities, an application of bone conduction technology to hearing aids can effectively improve a defect in a method of sound transmission in the auditory canal. For more information on the application of bone conduction technology to hearing aids, please refer to the illustrative descriptions of the modalities below.

[039] Figure 1 is a structural diagram illustrating an acoustic device according to some embodiments in this present invention. As shown in Figure 1, in some embodiments, an acoustic device 1 may include one or more loudspeakers 10 and one or more ear hook components 20. One or more ear hook components 20 may be connected with one or more loudspeakers 10 and one or more ear hook components 20 may be hung on a user's ears, so that one or more loudspeakers 10 may be hung on the user's ears. In some embodiments, the count of one or more loudspeakers 10 may be two, the count of one or more ear hook components 20 may be two, the two loudspeakers 10 and the two ear hook components 20 may be arranged in a one-to-one correspondence. The count of one or more loudspeakers 10 and the count of one or more ear hook components 20 may be selected according to actual use. For example, when the acoustic device is a bone conduction hearing aid, if the user has hearing loss in one ear, the count of one or more speakers 10 and one or more ear hook components 20 may be one; if the user has hearing loss in both ears, the count of speakers 10 and ear hook components 20 may be two. In some embodiments, the acoustic device may further include a rear hook component 30, and the rear hook component may be connected between the two ear hook components 20, so that the ear hook components 20 may be more stable in the user's ears.

[040] In some embodiments, the acoustic device 1 may include two loudspeakers 10, two ear hook components 20 and a rear hook component 30. One end of the two ear hook components 20 may be connected to a loudspeaker 10, that is, the two ear hook components 20 connect respectively to a loudspeaker 10. The rear hook component 30 connects the other end of the two ear hook components 20 from their corresponding loudspeakers 10. In some embodiments, the acoustic device 1 may also include one or more pickup components 40.

[041] One or more loudspeakers 10 can be configured to transform audio into a mechanical vibration of different frequencies. When using the acoustic device 1, one or more loudspeakers 10 can be fitted to the user's head near the ears, and then the mechanical vibration can be transmitted to the human auditory system through the skull bone. One or more ear hook components 20 can be configured to hang on the user's ears. In some embodiments, the two ear hook components 20 can be provided with a battery component 50 and a control circuit component 60. The control circuit component 60 can be configured to control an operation of the entire acoustic device 1, such as increasing and decreasing volume, switching on/off, headphone mode selection, wireless connection or data transmission, etc. The battery component 50 can be configured to power the entire acoustic device 1.

[042] When using acoustic device 1, the back hook component 30 can be placed around the back of the user's head. The back hook component 30 can be connected between the other ends of the two ear hook components 20, whose structure is reliable and stable, so that acoustic device 1 can be used stably.

[043] In some embodiments, the back hook component 30 may be a rod. In some embodiments, the back hook component 30 may be an arc to match the shape of the user's head. In some embodiments, the back hook component 30 may contour the top or back of the user's head. In some embodiments, the back hook component 30 may include a telescopic structure, so that the user can adjust the length of the back hook component 30 and have a comfortable wearing experience.

[044] The pickup component 40 can be arranged in a plurality of positions in the acoustic device. In some embodiments, the pickup component 40 can be arranged in one or more loudspeakers 10. In some embodiments, the pickup component 40 can be arranged in one or more ear hook components 20. In some embodiments, the pickup component 40 can be arranged in the rear hook component 30. In some embodiments, the pickup component 40 can be arranged at the end of one or more ear hook components 20 away from one or more loudspeakers 10. Arranging the pickup component 40 at the end of one or more ear hook components 20 away from one or more loudspeakers 10 can improve the "howling" situation of the pickup component 40. For details, see the relevant explanations below.

[045] The acoustic device 1 including a plurality of pickup components 40 may be taken as an example for explanation. In some embodiments, the plurality of pickup components 40 may be arranged in at least two of the two loudspeakers 10 and the rear hook component 30. In some other embodiments, the plurality of pickup components 40 may be spaced in the rear hook component 30. The plurality of pickup components 40 may be separate and independent of each other, so that they may independently perform the pickup and amplification of the signal. It should be explained that the "plurality of" described in the embodiment refers to "at least two", such as "two", "three", "four", etc.

[046] In some embodiments, one of the plurality of pickup components 40 may be arranged on the rear hook component 30 and may be arranged in an intermediate position of the rear hook component 30. In some embodiments, the intermediate position of the rear hook component 30 may be a midpoint of the rod-shaped rear hook component 30. In some embodiments, at least two pickup components 40 may be arranged on the rear hook component 30 and one of which may be arranged in the midpoint position of the rear hook component (e.g., the midpoint of the rod-shaped rear hook component 30). The remaining pickup component 40 may be arranged on one or two sides of the intermediate position and the at least two pickup components 40 may be spaced apart. In some other embodiments, the acoustic device 1 may include three pickup components 40, two of which may be arranged in a one-to-one correspondence on the two ear hook components 20 and the other may be arranged on the rear hook component 30. The above pickup components 40 may be independent of each other and may independently perform the pickup and amplification of the signal and may process sounds of different orientations independently, so that the hearing impaired may adapt to sounds of different orientations and the hearing effect of the hearing impaired may be improved.

[047] In some embodiments, the plurality of pickup components 40 may be spaced in a length direction of the rear hook component 30. In some embodiments, the distance between two adjacent pickup components 40 may be equal. In some other embodiments, the distance between any two adjacent pickup components 40 may be different.

[048] In some embodiments, to apply bone conduction technology to a hearing aid headset, one or more loudspeakers 10 need to have a good sound conduction effect, which is used to transmit an audio signal in the form of a mechanical vibration. Normally, if there is a large vibration of the air inside one or more loudspeakers 10, the sound conduction effect of the mechanical vibration of one or more loudspeakers 10 can be affected and the sound quality can be reduced, thus affecting the hearing effect of the hearing impaired. In some embodiments, one or more loudspeakers 10 can be configured according to the following descriptions of the embodiments of the present invention. In some other embodiments, the following one or more loudspeakers 10 can also be applied to other types of bone conduction acoustic devices, which are not limited to the acoustic device 1 described in the present invention.

[049] Figure 2 is a schematic diagram illustrating a disassembled structure of an acoustic device according to some embodiments of the present invention; Figure 3 is a schematic diagram illustrating a cross-section of the acoustic device in Figure 1 along section line A-A; Figure 4 is a schematic diagram illustrating another cross-section of the acoustic device in Figure 1 along section line A-A; Figure 5 is a schematic diagram illustrating a disassembled structure of a protective component and an upper cover of an acoustic device in Figure 4; Figure 6 is a schematic diagram illustrating another cross-section of the acoustic device along section line A-A in Figure 1. In some embodiments, the acoustic device described in Figures 2-6 may be a specific embodiment of one or more loudspeakers 10 in Figure 1.

[050] As shown in figures 2 to 6, in some embodiments, an acoustic device 200 may include one or more shell-type enclosures 11, one or more loudspeakers 12 and one or more protective components 13. One or more loudspeakers 12 may be bone conduction loudspeakers. One or more protective components 13 may be mesh structures with meshes. One or more loudspeakers 12 may be housed in one or more shell-type enclosures 11. One or more protective components 13 may be supported in one or more shell-type enclosures 11, which may be used to protect one or more loudspeakers 12.

[051] As shown in Figure 2, in some embodiments, each of the one or more shell-type enclosures 11 may have an accommodation cavity 110 and an opening 111. The side of each or more shells 11 with the opening 111 may be used to fit the user's head. The accommodation cavity 110 may be configured to accommodate one or more loudspeakers 12. A portion of each or more loudspeakers 12 may be extended out of the accommodation cavity 110 through the opening 111, so that a mechanical vibration generated by the one or more loudspeakers 12 may be transmitted to the user's head.

[052] In some embodiments, an inner wall of each or more shell-type enclosures 11 may be provided with a bearing platform 112. In some embodiments, the bearing platform 112 may be a ring. The inner wall of each of the one or more shell-type enclosures 11 refers to the inner wall of each of the one or more shell-type enclosures 11 that form the housing cavity 110. The bearing platform 112 may be disposed adjacent to the opening 111. In some embodiments, the bearing platform 112 may be used to support each of the one or more protective components 13. In some embodiments, when each of the one or more protective components 13 is supported on the bearing platform 112, each or more of the protective components 13 may cover or roughly cover the opening 111, thus protecting one or more loudspeakers 12. In some embodiments, the protective components 13 covering the openings may be understood as being the openings 111 covered by the protective components 13.

[053] In some embodiments, the bearing platform 112 may also be in other forms. In some embodiments, the bearing platform 112 may include a plurality of protruding structures arranged on the inner wall. The plurality of protruding structures may be spaced along a specified direction. For example, when the housing cavity 110 is a cylinder, the plurality of protruding structures may be spaced along the circumference of the cylinder to form a non-continuous annular bearing platform.

[054] In some embodiments, each of the one or more loudspeakers 12 may include a vibration component 121 and a vibration transmission plate 122. In some embodiments, the vibration component 121 may include a voice coil and a magnetic circuit component (not shown in the figure). In some embodiments, at least a portion of the elements of the vibration component 121 may be accommodated within the accommodation cavity 110. For example, the vibration diaphragm of the vibration component 121 may be accommodated within the accommodation cavity. The vibration transmission plate 122 can be connected to the vibration component 121 and exposed at the opening 111. In some embodiments, the vibration transmission plate 122 exposed at the opening 111 may refer to the vibration transmission plate 122 that extends through the opening 111 to the outside of the housing cavity 110. One or more loudspeakers 12 may project from the inside of one or more shell-type enclosures 11 outwards, and the vibration transmission plate 122 may extend through the opening 111 to the outside of the housing cavity 110 and be exposed. Upon receiving an audio signal, one or more vibration components 121 may convert the audio signal into a mechanical vibration and transmit the vibration from one or more loudspeakers 12 through the vibration transmission plate 122 to a user's bone (such as a skull) and then to a human auditory nerve.

[055] In some embodiments, one or more speakers 12 may be completely located within the housing cavity 110. In some embodiments, the vibration transmission plate 122 may be at the same level with the opening 111 in terms of position. In some embodiments, the vibration component 121 may be extended outside the housing cavity 110 through the opening 111.

[056] In some embodiments, one or more protective components 13 may be disposed at the opening end of each of the shell-type enclosures 11 and may fit into the vibration transmission plate 122. For example, one or more protective components 13 may fit into one end of the vibration transmission plate 122 away from the vibration component 121. In some embodiments, as shown in Figures 3-4, each of the one or more protective components 13 may include a fitting portion 131 (i.e., the first portion of the protective component 13), an annular wall portion 132, and a support portion 133 (the annular wall portion 132 and the support portion 133 may be the second portion of the protective component 13). In some embodiments, the support portion 133 may be a ring. In some embodiments, the fitting portion 131 and the annular wall portion 132 may form a cylindrical accommodation portion. In some embodiments, the vibration transmission plate 122 may be disposed in the cylindrical accommodation portion. The fitting portion 131 can be connected to one end of the annular wall portion 132 to seal one end of the accommodation portion, and the fitting portion 131 can be fitted with an outer end surface (the end surface away from the vibration component 121) of the vibration transmission plate 122. Specifically, one end of the cylindrical accommodation portion can refer to the end of the cylindrical accommodation portion away from the accommodation cavity 110, and the other end of the cylindrical accommodation portion can refer to the end of the cylindrical accommodation portion near the accommodation cavity 110. The outer end surface of the vibration transmission plate 122 refers to the end surface away from the accommodation cavity 110, or the end surface away from the vibration component 121. During the component-specific process, each of the one or more protective components 13 can be covered in the opening 111 and the vibration transmission plate. 122 can be extended into the cylindrical accommodation portion, and the outer end surface of the vibration transmission plate 122 can be fitted with the fitting portion 131. The support portion 133 can be connected to the other end of the annular wall portion 132 and extend toward the outside of the ring wall portion 132. The support portion 133 can be configured to support the opening end of each of the shell-type housings 11. In some embodiments, the support portion 133 can be supported on the bearing platform 112 (such as the annular bearing platform). In some embodiments, an adhesive layer can be provided between the support portion 133 and the bearing platform 112 to bond the support portion 133 and the bearing platform 112.

[057] By the arrangement of the vibration transmission plate 122 connecting the vibration component 121 extending out of the accommodation cavity of the opening 111 and using each of the protective components 13 to fit the vibration transmission plate 122, the vibration transmission plate 122 can be closer to the user's head and the vibration of the vibration transmission plate 122 can be transmitted to the user's bone more quickly and powerfully. The mechanical vibration can be more complete and less likely to lose a frequency band in the embodiments of the present invention patent, thus effectively improving an auditory effect for the hearing impaired. Furthermore, since each of the one or more protective components 13 has a mesh structure, the air inside and outside the housing cavity 110 can communicate with each other in the process of mechanical vibration described above to balance a pressure difference between the air inside and outside the housing cavity 110, thus reducing the sound generated by the vibration of the air inside the housing cavity 110, attenuating the sound generated by the vibration of the air that is different from the sound generated by the mechanical vibration of the vibration transmission plate 122, and as a result, sound leakage can be reduced. Compared to a sealed cavity structure 110, the protective component 13 can reduce the effect of air vibration in the housing cavity 110 on the vibration transmission plate 122, thus effectively improving the sound quality and sound effect of the acoustic device 200.

[058] In some embodiments, the acoustic device 200 may include an upper cover 14 and at least a portion of the support portion 133 may be clamped between the upper cover 14 and the bearing platform 112, so that the support portion 133 of each of the protective components 13 may be pressed into the bearing platform 112. Therefore, the support portion 133 may be stably supported on the bearing platform 112 to prevent a fall of each of the protective components 13. In some embodiments, the upper cover 14 may be annular.

[059] In some embodiments, the adhesive layer may be placed between the support portion 133 and the top cover 14 to join the support portion 133 and the top cover 14.

[060] In some embodiments, the shape of the top cover 14 may be consistent with the shape of the bearing platform 112. For example, when the bearing platform 112 is annular, the top cover 14 may also be annular. As another example, when the bearing platform 112 includes a plurality of protruding structures, the top cover 14 may include a plurality of protruding platforms. When the top cover 14 presses the second portion onto the bearing platform 112, the plurality of protruding platforms may be arranged above the plurality of protruding structures in a one-to-one correspondence, or the plurality of protruding platforms and the plurality of protruding structures may be staggered.

[061] For a positional relationship between the top cover 14, the support portion 133 and the bearing platform 112, there may be the following implementation modes:

[062] In some embodiments, as shown in Figure 3, the support portion 133 may be clamped between the upper cover 14 and the bearing platform 112. An outer surface (or an upper surface) of the support portion 133 may be close to the upper cover 14, an annular inner surface (or a lower surface) of the support portion 133 may be close to the bearing platform 112. As described in the present invention, the inner surface of each of the protective components 13 refers to a surface that fits an end surface of the vibration transmission plate 122 away from the vibration component 121. The inner surface of the support portion 133 refers to the portion of the inner surface of each or more protective components 13 in an annular support portion 133. Correspondingly, the outer surface of each of the protective components 13 may be disposed opposite the inner surface of each or more protective components 13. The surface The outer surface of the support portion 133 refers to the outer surface portion of each of the one or more protective components 13 in the annular support portion 133. In some embodiments, the top cover 14 may directly attach to the outer surface of the support portion 133 and then attach the inner surface of the support portion 133 to the annular bearing platform 112. In other words, the support portion 133 extends from the inside of a gap between the annular top cover 14 and the bearing platform 112 to the outside of the gap. A portion of the structure in Figure 1 is shown in Figure 3, while the vibration component 121 is not shown in Figure 3.

[063] In some embodiments, an adhesive layer may be disposed between the inner surface of the support portion 133 and the bearing platform 112 to directly or indirectly bond the support portion 133 and the bearing platform 112. Furthermore, an adhesive layer may be disposed between the outer end surface of the vibration transmission plate 122 and the fitting portion 131 to bond the vibration transmission plate 122 and the fitting portion 131. In an actual component process, one or more protective components 13 may be directly or indirectly fixed to the vibration transmission plate 122 and one or more shell-type housings 11 by means of adhesive simultaneously to form the adhesive layer above, and then the top cover 14 may be applied to the support portion 133. Naturally, there may also be an adhesive layer between the outer surface layer of the support portion 133 and the top cover 14, which bonds the support portion. 133 and the top cover 14

[064] Connecting one or more protection components 13 using the method described in figure 3 above can simplify the structures of one or more loudspeakers 12 and facilitate the assembly of one or more loudspeakers 12. In addition, the support for one or more protection components 13 can also be more stable.

[065] In some embodiments, as shown in Figure 6, the inner surface of the support portion 133 may enclose an edge portion of the top cover 14 and the support portion 133 may be folded and extended between the top cover 14 (such as an annular cover) and the bearing platform 112 (such as an annular platform), and the outer surface of the support portion 133 may be close to the bearing platform 112. In some embodiments, the inner surface of the support portion 133 may enclose the edge portion of the top cover 14 and then the support portion 133 may extend from the outside inwards through the gap between the top cover 14 and the bearing platform 112. A portion of the structure in Figure 1 is shown in Figure 6, while the vibration component 121 is not shown in Figure 6.

[066] In some embodiments, as shown in figures 5 and 6, the support portion 133 may include an annular subportion 1331 (i.e., a portion of the extended portion) and a bending subportion 1332 (i.e., a bending portion). Annular subportion 1331 can connect to annular wall portion 132 and extend outward from annular wall portion 132. Bending subportion 1332 can connect to an edge of annular subportion 1331 that extends outward from annular wall portion 132, i.e., bending subportion 1332 can be connected to the edge of annular subportion 1331 that extends outward from annular wall portion 132 and can extend away from the edge of annular subportion 1331. In some embodiments, the bending subportion 1332 can be multiple and can extend respectively outward from the edge of bending subportion 1331. Bending subportion 1332 can be spaced at the edge of annular subportion 1331. In some embodiments, the The bending sub-portion 1332 may also be a continuous ring extending outward from the edge of the annular sub-portion 1331.

[067] In some embodiments, the annular subportion 1331 may enclose the edge portion of the top cover 14 and the bending subportion 1332 may extend from the annular subportion 1331 to between the top cover 14 and the bearing platform 112. The inner surface of the support portion 133 may be close to the top cover 14. In some embodiments, the inner surface of the annular subportion 1331 and the inner surface of the bending subportion 1332 may be close to the top cover 14. The outer surface of the support portion 133 may be close to the bearing platform 112. Specifically, the outer surface of the bending subportion 1332 may be close to the bearing platform 112.

[068] In some embodiments, an adhesive layer may be disposed between the outer surface of the support portion 133 and the bearing platform 112 to fix the support portion 133 and the bearing platform 112. An adhesive layer may also be disposed between an outer end surface of the vibration transmission plate 122 and the fitting portion 131 to fix the vibration transmission plate 122 and the fitting portion 131. In an effective component process, one or more protective components 13 may first enclose the top cover 14 and then be fixed with the vibration transmission plate 122 and one or more shell-type enclosures 11 by means of the adhesive simultaneously, and then the adhesive layer above may be formed. In some embodiments, an adhesive layer may be disposed between the inner surface of the support portion 133 and the top cover 14 to fix the support portion 133 and the top cover 14.

[069] Through the embodiment of figure 6, one or more protective components 13 can be fixed. Compared with the direct fixing of the support portion 133 between the upper cover 14 and the bearing platform 112, as described in figure 3, enclosing the upper cover 14 with the inner surface of the support portion 133 can prevent the formation of a gap between one or more protective components 13 and an inner surface of the upper cover 14 (the surface facing the housing cavity 110), and based on the effective support of the support portion 133, enclosing the upper cover 14 with the inner surface of the support portion 133 can further prevent dust accumulation in the gap above, which can block one or more protective components 13 and reduce the failure rate of the acoustic device.

[070] In some embodiments, as shown in Figure 4, the top cover 14 may include a first body 141 and a second body 142 arranged in layers. The first body 141 may be closer to the bearing platform 112 (such as the annular bearing platform) than the second body 142, and the second body 142 may be supported on the bearing platform 112. The support portion 133 may be fixed between the first body 141 and the second body 142. In some embodiments, the inner surface of the support portion 133 (such as the lower surface shown in Figure 4) may be close to the first body 141, and the outer surface of the support portion 133 (such as the upper surface shown in Figure 4) may be close to the second body 142. A portion of the structure in Figure 1 is shown in Figure 4, while the vibration component 121 is not shown in Figure 4.

[071] In some embodiments, one or more protective components 13 may form a whole with the top cover 14 through an injection molding technology. An injection mold used in injection molding technology may also be called an overmolding. In some embodiments, the injection mold may include at least two sets of plastic molds. One set of plastic molds may be used to make a harder portion, and then the hard portion formed may be placed in another set of plastic molds for injection molding. Taking one or more protective components 13 and the top cover 14 forming a whole using injection molding technology as an example, a material of the top cover 14 may be a rigid plastic, whose hardness is greater than the hardness of one or more protective components 13. One or more protective components 13 may be formed first, then one or more protective components 13 may be placed in a mold corresponding to the top cover 14, and then the top cover 14 may be formed and a structure in which the first body 141 and the second body 142 hold the support portion 133 of one or more protective components 13. In some other embodiments, a connection method between one or more protective components 13 and the top cover 14 may also be: an adhesive layer may be disposed between the inner surface of the support portion 133 and the first body 141 (applying an adhesive, which may form an adhesive layer after solidification), which joins the support portion into 133 and the first body 141. An adhesive layer may be placed between the outer surface of the support portion 133 and the second body 142, which joins the support portion 133 and the second body 142.

[072] After one or more protective components 13 and the top cover 14 form a whole, an adhesive layer may be disposed between the first body 141 and the bearing platform 112 (such as the annular bearing platform) and then the first body 141 and the bearing platform 112 may be fixed. An adhesive layer may also be disposed between the outer end surface of the vibration transmission plate 122 and the fitting portion 131, thus fixing the vibration transmission plate 122 and the fitting portion 131.

[073] In some embodiments, the support portion 133 and the first body 141, and the support portion 133 and the second body 142 may also be connected to each other by tightening, threaded connection, etc.

[074] In some embodiments, the inner surface of the support portion 133 (such as the annular support portion) may enclose an edge portion of the second body 142 and the support portion 133 (such as the annular support portion) may be folded and extended from the rolled edge portion of the second body 142 towards the accommodation portion between the first body 141 and the second body 142.

[075] By arranging the top cover 14 to include the first body 141 and the second body 142 according to the embodiment described in figure 4, the first body 141 and the second body 142 can be made as a whole with one or more protective components 13 in advance, which is convenient for later assembly with one or more shell-type enclosures 11. The fastening of the first body 141 and the second body 142 (i.e., one or more protective components 13 can be fastened between the first body 141 and the second body 142, and the two surfaces of each of one or more protective components 13 can fit respectively into the first body 141 and the second body 142) can make the fastening of one or more protective components 13 more stable.

[076] In some embodiments, since the opening 111 is sealed, for example, each of the one or more shell-type enclosures 11 is entirely encased with a silica gel, the air within the housing cavity 110 can vibrate and produce sound. For example, the vibration of the air can cause a large resonant peak of natural frequency within 20Hz to 20,000Hz when one or more loudspeakers 10 operate, resulting in a serious sound leakage and howling and reducing the sound effect of one or more loudspeakers 12.

[077] In some embodiments, using one or more mesh-structured protective components 13 instead of sealing the opening 111, the air inside and outside the accommodation cavity 110 can communicate with each other, so that the resonant peak can be effectively reduced, thus effectively reducing sound leakage. One or more protective components 13 of the present invention have a plurality of meshes that are distributed in some positions of one or more protective components 13, or the meshes can be spread throughout the entirety of each or more protective components 13. For example, the meshes can be arranged in the annular wall portion 132. For another example, the meshes can be arranged in the support portion 131, in the ring wall portion 132 and in the annular support portion 133, but as the mesh structure is dense and subtle, it is not specifically shown in Figure 2-Figure 8.

[078] In some embodiments, the mesh count of each of the one or more protective components 13 may be 250-600. In some embodiments, the mesh count of each of the one or more protective components 13 may be 300-500. In some embodiments, the mesh count of each of the one or more protective components 13 may be 380-480 and the mesh count of each of the one or more protective components 13 may be 400-430. In some embodiments, the thickness of each of the one or more protective components 13 may be from 0.01 mm to 0.3 mm. In some embodiments, the thickness of each of the one or more protective components 13 may be from 0.05 mm to 0.25 mm. In some embodiments, the thickness of each of the one or more protective components 13 may be from 0.1 mm to 0.2 mm. In some configurations, the thickness of each or more protective components 13 can be from 0.125 mm to 0.15 mm. The mesh count and thickness designs of each or more protective components 13 can more effectively reduce sound leakage and ensure a higher intensity of each or more protective components 13.

[079] In some embodiments, a material of one or more protective components 13 may be at least one of PC (polycarbonate), PET (polyethylene terephthalate glycol) and nylon. In some embodiments, the material of one or more protective components 13 may be a metallic material or an alloy material, such as steel and aluminum. In some embodiments, the material of one or more protective components 13 may be a fiber material, such as carbon fiber, fiberglass, etc.

[080] In some embodiments, one or more protective components 13 may be thermoformed, which causes one or more protective components 13 to form a structure that includes the support portion 131, the annular wall portion 132 and the annular support portion 133. Specifically, the following embodiment may be used to improve the performance and structural stability of one or more protective components 13.

[081] In some forms, one or more protective components 13 can be made by means of 3D printing.

[082] The beneficial effects of the present invention include: the present invention applies bone conduction technology to the hearing aid device, which can solve the problem of a limited improvement in the hearing effect of the hearing impaired using a traditional hearing aid. Furthermore, by arranging the vibration transmission plate 122 to extend out of the accommodation cavity 110 through the opening 111 and fitting one or more protective components 13 with the transmission plate 122, the vibration transmission plate 122 can be directly closer to the user's head and the vibration of the vibration transmission plate 122 extended out of the accommodation cavity 110 can be transmitted to the user's bones more quickly and powerfully, which in turn makes the transmission of mechanical vibration more complete and less likely to lose the frequency band, effectively improving the hearing effect of the hearing impaired. Furthermore, due to the mesh structure of one or more protective components 13, the air inside and outside the accommodation cavity 110 can communicate with each other, thus reducing the sound caused by air vibration in the accommodation cavity 110, attenuating the sound generated from air vibration in addition to mechanical vibration, and sound leakage can be effectively reduced. Moreover, compared with a sealed accommodation cavity structure 110, one or more protective components 13 with a mesh structure can further reduce the impact of air vibration on the mechanical vibration of the vibration transmission plate 122 in the accommodation cavity 110, and the sound quality and hearing aid effect of the acoustic device 200 can be effectively improved.

[083] The present invention patent also provides a production method for preparing the acoustic device's protective component. The method may include the following operations.

[084] In S1, a combination can be formed by fitting the mesh structure (e.g., a gauze element) and a coating material, wherein the hardness of the coating material is greater than the hardness of the mesh structure.

[085] In S2, a molded combination can be obtained by molding the combination using a molding technique. In some embodiments, the molding technology may include a thermoforming technology, a coating technology, a 3D printing molding, etc. In some embodiments, the combination may be formed by thermoforming. In some other embodiments, the combination may be formed first by thermoforming and then coating. In some other embodiments, the combination may be formed by coating first and then thermoformed.

[086] In S3, one or more protective components can be obtained based on the molded combination. The molded combination in S3 can be the combination formed by coating and then thermoforming, and it can also be the combination formed by thermoforming and then coating, or it can be the combination formed by direct thermoforming. After separating the coating material and the mesh structure from the molded combination, a molded mesh structure can be obtained (i.e., one or more protective components). The molded mesh structure can constitute each of the one or more protective components with a first portion and a second portion. The first and second portions can form a cylindrical structure. At least one portion of the second portion can form a cylindrical wall of the cylindrical structure (for example, an annular wall, i.e., an annular wall, for example, annular wall portion 132 in Figure 3); The first portion may form a lower wall of the cylindrical structure (e.g., the fitting portion 131 in Figure 3). The first and second portions may form the accommodation cavity. In some embodiments, the first portion may be approximately perpendicular to the second portion. In some embodiments, the second portion may include the cylinder wall of the cylindrical structure and a lateral portion extending in a direction approximately perpendicular to the cylinder wall (e.g., the support portion 133 in Figure 3). In some embodiments, the mesh structure may be further processed according to the usage requirements of one or more protective components, such as adding grooves or threaded holes in the mesh structure.

[087] In some embodiments, thermoforming can be performed directly on the mesh, so that the mesh can form each of the one or more protective components with the first portion and the second portion.

[088] The present invention patent further provides a mesh component, which can be applied to the loudspeaker of the acoustic device in the invention patent above. Figure 7 is a schematic diagram illustrating a disassembled structure of a mesh component according to some embodiments of the present invention patent. Figure 8 is a structural schematic diagram illustrating a cross-section of an adjusted mesh component according to some embodiments of the present invention patent. Figure 9 is a schematic diagram illustrating a preparation flow of the mesh component according to some embodiments of the present invention patent. As shown in Figure 7, the mesh component of the embodiment may include one or more protective components 13 and the sheathing material 15 fitted together.

[089] In some embodiments, as shown in figures 7 to 9, one or more protective components 13 (which may refer to a molded mesh) and the coating material 15 (which may refer to a molded coating material) may obtain corresponding structures after performing thermoforming on the mesh and the coating material. For example, one or more protective components 13 (which may refer to the molded mesh) may include the interlocking portion 131, the annular wall portion 132, and the support portion 133. The interlocking portion 131 may be used to seal one end of the annular wall portion 132, the support portion 133 may be connected to the other end of the annular wall portion 132 and extend toward the outside of the annular wall portion 132. The hardness of the coating material 15 may be greater than the hardness of one or more protective components 13, and the coating material 15 and one or more protective components 13 may have the same shape after molding, thus supporting one or more protective components 13 to maintain their shape after thermoforming. In some embodiments, the material of the coating material 15 may be plastic.

[090] In some embodiments, where the hardness of the coating material 15 is greater than the hardness of one or more protective components 13, when one or more protective components 13 and the coating material 15 are molded together by thermoforming, the coating material 15 and one or more protective components 13 can deform into the corresponding shape together. At this point, the two can be shaped and the coating material 15 can support one or more protective components 13 to maintain the corresponding shape. During assembly, one or more protective components 13 can be mounted in one or more housings 11.

[091] The specific method for preparation using the above-mentioned solution to form one or more protective components 13 may refer to the detailed descriptions in Figure 9 and Figure 10.

[092] Figure 9 is a flowchart that illustrates a mesh component preparation process according to some embodiments of the present invention.

[093] As shown in figure 9, a 900 process may include the following operations.

[094] In S11: an original 13C mesh and an original 15B coating material can be prepared and assembled;

[095] S12: stamping can be performed on the original mesh 13C fitted and on the original lining material 15B, obtaining one or more protective components 13 and the lining material 15 of a predetermined size;

[096] S13: After fitting one or more protective components 13 and the coating material 15, thermoforming can be performed, the coating material 15 and one or more protective components 13 can be shaped so that the coating material 15 can support one or more protective components 13 to maintain its shape after thermoforming. Each of the one or more protective components 13 after thermoforming can include the fitting portion 131, the annular wall portion 132 and the support portion 133. The fitting portion 131 can be used to seal one end of the annular wall portion 132, the support portion 133 can be connected to the other end of the annular wall portion 132 and extend towards the outside of the annular wall portion 132;

[097] S14: the coating material 15 can be peeled off and one or more protective components 13 can be obtained.

[098] Figure 10 is a flowchart that illustrates another process for preparing the mesh component according to some embodiments of the present invention.

[099] As shown in figure 10, a process 1000 may include the following operations.

[0100] In S21: an original 13C mesh and an original 15B coating material can be prepared.

[0101] S22: Thermoforming can be performed on the original mesh 13C and the original coating material 15B. The coating material 15 and one or more protective components 13 can be formed so that the coating material 15 can support one or more protective components 13 to maintain the shape after thermoforming.

[0102] S23: the covering can be carried out on the original mesh 13C and the original sheathing material 15B after thermoforming and obtain one or more insulating protective components 13 and sheathing material 15. One or more protective components 13 may include the interlocking portion 131, the annular wall portion 132 and the support portion 133. The interlocking portion 131 can be used to seal one end of the annular wall portion 132, the support portion 133 can be connected to the other end of the annular wall portion 132 and extend towards the outside of the annular wall portion 132;

[0103] S24: the coating material 15 can be peeled off and one or more protective components 13 can be obtained.

[0104] The embodiment uses the coating material 15 to assist one or more protective components 13 in performing thermoforming. Because the hardness of the coating material 15 is greater than the hardness of one or more protective components 13, after thermoforming, the coating material 15 can support one or more protective components 13 to maintain their shape, thus obtaining one or more protective components 13 with a stable shape and structure, improving the yield and structural stability of one or more protective components 13 and facilitating subsequent assembly to one or more corresponding shell-type enclosures 11. Furthermore, since one or more protective components 13 can effectively maintain their shape after thermoforming, they can fit into the structures and shapes of one or more loudspeakers 12 and can effectively fit into the outer end surface of the vibration transmission plate 122. The stable mesh structure of each or more protective components 13 can allow air communication in and out of the housing cavity 110, thus reducing the sound caused by air vibration in the housing cavity 110, attenuating the sound generated by air vibration in addition to mechanical vibration, and sound leakage can be effectively reduced. Compared with the sealing structure of the housing cavity 110, one or more protective components 13 can reduce sound leakage from loudspeaker components 10.

[0105] The mesh component of the modality can improve the structural stability of one or more protective components 13 and helps to improve the hearing aid effect of the acoustic device 200.

[0106] Figure 11 is a schematic diagram illustrating an acoustic device according to some embodiments of the present invention. As shown in Figure 11, an acoustic device 1100 (for example, a bone conduction loudspeaker, a bone conduction headset, etc.) may include a support component 1102, a magnetic circuit component 1104, a vibration component 1106 and one or more protection components 1108.

[0107] The support component 1102 may support the magnetic circuit component 1104, the vibration component 1106 and/or one or more protective components 1108. The support component 1102 may include one or more shell-type enclosures, one or more connectors, etc. One or more shell-type enclosures may form an accommodation cavity to accommodate at least the magnetic circuit component 1104 and the vibration component 1106, and one or more shell-type enclosures may be used to install one or more protective components 1108. One or more connectors may connect one or more shell-type enclosures and the magnetic circuit component 1104, and the connectors may further connect the vibration component 1106 and one or more protective components 1108. In some embodiments, one or more shell-type enclosures may have openings. In some embodiments, the openings can be used to equalize changes in air pressure in the housing cavity during a vibration process of the vibration component 1106. In some embodiments, the openings can be used to install the magnetic circuit component 1104 and/or the vibration component 1106 in the housing cavity.

[0108] In some embodiments, the support component 1102 may include a bearing platform, and the bearing platform may be arranged in one or more shell-type enclosures. The bearing platform may be used to support one or more protective components 1108. In some embodiments, the bearing platform may be annular. In some embodiments, the support component 1102 may include a top cover, and the top cover and the bearing platform may be used to secure the protective component 1108, so that one or more protective components 1108 may be stably attached to the support component 1102. In some embodiments, the top cover may be annular. In some embodiments, the top cover may include a first body and a second body arranged in layers. The first body and the second body may be used to secure one or more protective components 1108. In some embodiments, the first body and the second body may be annular.

[0109] Magnetic circuit component 1104 can provide a magnetic field. The magnetic field can be used to convert a signal containing sound information into a vibration signal. In some embodiments, the sound information may include a video or audio file with a specific data format, or data or a file that can be converted into sound via a specific channel.

[0110] The vibration component 1106 can produce a mechanical vibration. The generation of vibration is accompanied by energy conversion; the acoustic device can use the specific magnetic circuit component 1104 and the vibration component 1106 to perform a conversion of a signal containing sound information into mechanical vibration. The conversion process can involve the coexistence and conversion of a variety of different types of energy. For example, in the present invention, an electrical signal can be directly converted into mechanical vibration through a transducer to generate sound. In some embodiments, the vibration component 1106 can convert an audio signal (e.g., the electrical signal) into a mechanical vibration signal under the action of a magnetic field and transmit the mechanical vibration signal through the skin, bone, etc. of a user to the auditory center so that the user can hear the sound. In some embodiments, the vibration component 1106 may include a voice coil, a vibrating plate, and a vibration transmission plate. The voice coil can be placed in a magnetic gap formed by the magnetic circuit component 1104. The voice coil can vibrate under the action of the magnetic field; after the passage of the electrical signal (i.e., the audio signal), the voice coil can be physically connected to the vibrating plate to transmit the vibration to the vibrating plate. The vibration transmission plate can be physically connected to the vibrating plate so that the vibration generated by the vibration component 1106 can be transmitted to the human bone. As described in the present invention, the magnetic circuit component 1104 and the vibration component 1106 can be called a transducer or loudspeaker. In some embodiments, the vibration component 1106 may include the magnetic circuit component 1104. In some embodiments, the acoustic device 1100 can perform the conversion of the audio signal to a mechanical signal through another component.

[0111] One or more protective components 1108 may be used to prevent a foreign object (such as dust, dander, etc.) from entering the interior of one or more shells through the opening in the shells. One or more protective components 1108 may protect the magnetic circuit component 1104 and the vibration component 1106 to extend the service life of the acoustic device. At least part of the protective component 1108 and the vibration component 1106 may be physically connected to transmit the vibration of the vibration component 1106 to the outside world. The protective component 1108 includes a mesh structure to make the housing cavity communicate with the outside world. In some embodiments, one or more protective components 1108 may include a first portion and a second portion, and the second portion may be connected to the first portion. The first and second portions can form an accommodation portion, which can be used to accommodate at least one portion of the vibration component 1106. For example, the vibration transmission plate can be located in the accommodation portion, and the first portion can fit an end surface of the vibration transmission plate away from the vibration component 1106; that is, the first portion can be used to seal one end of the accommodation portion, and the first portion can fit the end surface of the vibration component 1106 (e.g., the vibration transmission plate) facing the opening. The shape of the accommodation portion varies. For example, the shape can be a sphere, a cylinder, an elliptical cylinder, a cone, or other irregular shapes, etc. In some embodiments, the second portion can be physically connected with one or more shells at the end with openings. In some embodiments, the second portion may be connected to one or more shell-type enclosures at the ends with openings by means of fastening, gluing, welding, threading, etc. In some embodiments, one or more protective components 1108 may include the mesh structure with meshes, and the meshes may allow air inside and outside the accommodation cavity to communicate with each other, so that the accommodation cavity can communicate with the outside world. In some embodiments, one or more protective components 1108 may be physically connected with one or more shell-type enclosures at the ends with openings.

[0112] In some embodiments, at least part of the outer surface of the second part may fit into the top cover and at least part of the inner surface of the second part may fit into the bearing platform to secure the second part between the top cover and the bearing platform.

[0113] In some embodiments, the second portion of each of the one or more protective components 1108 includes an annular wall portion (e.g., annular wall portion 132 in Figures 3-7) and a support portion (e.g., support portion 133 in Figure 3). The annular wall portion may be connected to the first portion and may extend toward the vibration component 1106, and the support port may be connected to an edge of the annular wall portion away from the first portion. The support portion may extend from an extension portion to between the top cover and the bearing platform, or between the first body and the second body. In some embodiments, the ring wall, the support portion, and the first portion may be connected by linkage, clamping, etc. In some other embodiments, the ring wall portion, a bending portion, and the first portion may form a whole to make each of the one or more 1108 protection components an integrated structure.

[0114] In some embodiments, the supporting portion of the second portion of each or more protective components 1108 (for example, the supporting portion 133 in Figure 6) may include a first sub-portion (for example, the annular sub-portion 1331 in Figure 6) and a second sub-portion (for example, the bending sub-portion 1332 in Figure 6). The first sub-portion may be approximately perpendicular to the second sub-portion. The first sub-portion and the second sub-portion may enclose an edge area or an entire area of the top cover (for example, the annular cover). The first sub-portion and the second sub-portion may be fixed between the top cover and a convex.

[0115] In some forms, when the upper covering includes the first body and the second body, at least part of the second part may be trapped between the first body and the second body. In other words, the two opposite sides of the second portion may touch the first body and the second body respectively.

[0116] Further descriptions of one or more protective components 1108 may be referred to in the descriptions of other parts of the present invention patent (for example, figures 2-7 and the detailed descriptions).
