[0036] To more clearly illustrate the technical solutions of the embodiments of this application, the following is a brief introduction to the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0037] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0038] It should be understood that the terms "data block," "system," "engine," "unit," "component," "module," and / or "block" used herein are a method of distinguishing different components, elements, parts, portions, or assemblies at different levels. However, other expressions may be used to replace the aforementioned terms if they can achieve the same purpose.

[0039] Various terms are used to describe the spatial and functional relationship between elements (e.g., between layers), including "connection", "engagement", "interface" and "coupling". Unless explicitly described as "directly", when describing the relationship between the first and second elements in this application, the relationship includes a direct relationship in which there are no other intermediate elements between the first and second elements, and an indirect relationship in which there are (spatially or functionally) one or more intermediate elements between the first and second elements. On the contrary, when an element is referred to as being "directly" connected, engaged, interfaced or coupled to another element, there is no intermediate element. In addition, the spatial and functional relationship between the elements can be achieved in various ways. For example, the mechanical connection between two elements can include a welded connection, a key connection, a pin connection, an interference fit connection, etc., or any combination thereof. Other words used to describe the relationship between the elements should be interpreted in a similar manner (e.g., "between", "between ... ", "adjacent" and "directly adjacent", etc.).

[0040] The present application provides an acoustic device. The acoustic device may include a housing, one or more pickup assemblies, and one or more channel members. The housing may have a storage space and one or more communication holes. Each communication hole connects the storage space to the outside world. The one or more pickup assemblies may be disposed within the storage space for picking up sound through the communication holes. The one or more channel members may be disposed within the storage space, wherein at least one of the one or more channel members is disposed between a pickup element in the one or more pickup assemblies and one of the one or more communication holes, such that the sound is transmitted through the communication hole and then to the pickup element through at least one of the one or more channel members. Therefore, by providing one or more channel members, the sound path of the corresponding pickup assembly can be extended, thereby improving the "wind noise" phenomenon caused by the pickup assembly's short sound path. In addition, in some embodiments, by providing multiple pickup assemblies that can independently perform sound pickup and signal processing (e.g., amplification), it is possible to adapt to sounds from different directions, allowing the wearer (e.g., a hearing-impaired person) to adapt to sounds from different directions and improve the wearer's hearing effect.

[0041] In some embodiments, the acoustic device may further include a plurality of speaker assemblies, a control circuit assembly and a plurality of interactive assemblies. The control circuit assembly may include a plurality of control elements, each control element corresponding to at least one speaker assembly among the plurality of speaker assemblies. Each interactive assembly corresponds to each speaker assembly among the plurality of speaker assemblies and its corresponding control element, and is configured to trigger, in response to receiving a user operation instruction, the control element corresponding to the interactive assembly to control the corresponding speaker assembly to implement the function corresponding to the user operation instruction. Therefore, for the hearing-impaired (for example, a user with normal hearing in one ear and hearing loss in the other ear), the two speaker assemblies can be adaptively adjusted according to actual usage needs to adapt to the different hearing of their two ears, thereby avoiding the sound heard being always "one side loud and the other side small", thereby improving the user experience.

[0042] Figure 1 This is a block diagram of an exemplary acoustic device according to some embodiments of the present application. The acoustic device 100 can pick up the user's voice, the ambient sound of the user's environment, etc., and convert the picked up sound into an audio signal (for example, an electrical signal). In some embodiments, the acoustic device 100 may include hearing aids, headphones (for example, noise reduction headphones, bone conduction headphones), listening bracelets, smart glasses, mobile phones, microphones, and other devices with sound pickup capabilities. Figure 1 As shown, the acoustic device 100 may include a support assembly 110 , a core module 120 and a channel member 130 .

[0043] The support assembly 110 may include a housing and a shell, with a communication hole provided in the shell. The communication hole may connect the housing to the outside world. In some embodiments, one or more components of the acoustic device 100 may be disposed in the housing. For example, the movement module 120 and the channel member 130 may be located in the housing. For another example, the movement module 120 may include multiple pickup assemblies. The multiple pickup assemblies may be spaced apart in the housing.

[0044] In some embodiments, the shell may include a first shell and a second shell. The first shell and the second shell may be coupled to form the accommodating space. The second shell may include a bottom wall and a side wall connected to the bottom wall. The first shell may be physically connected to the side wall to form the accommodating space. In some embodiments, a flange may be provided on the side of the bottom wall facing the first shell to form an accommodating groove that can accommodate the pickup assembly. The channel member 130 may be covered on the flange to press the pickup assembly into the accommodating groove. In the present application, the channel member pressing the pickup assembly into the accommodating groove may refer to a surface of the channel member and the accommodating groove forming an accommodating cavity, and the pickup assembly may fit with the side wall of the accommodating cavity when placed in the accommodating cavity.

[0045] In some embodiments, the shape of the support component 110 (e.g., a shell) can be set accordingly according to the specific use requirements of the acoustic device 100, and is not specifically limited here. For example, the acoustic device 100 may be a bone conduction hearing aid, and its support component 110 may cooperate with the user's auricle so that the bone conduction hearing aid can be hung on the user's ear and is not easy to fall off. The bone conduction hearing aid with the support component 110 may also be called an ear-hook hearing aid. For another example, the acoustic device 100 may be an open binaural headset, and its support component 110 may be hung horizontally on the top of the user's head, fixed to the human head in a form similar to a headband, and its two ends are a certain distance away from the user's ears. For another example, the support component 110 may be as follows Figure 2 The structure shown includes a first portion 212, a second portion 214, and a third portion 216. In some embodiments, the first portion 212 and the second portion 214 may also be referred to as an ear hook assembly. The third portion 216 may also be referred to as a back hook assembly. For more descriptions of the ear hook assembly and / or back hook assembly, please refer to other places in this application (e.g., Figure 2 、 Figure 3 and Figure 4 and its related descriptions).

[0046] In some embodiments, the support assembly 110 can be made of metal materials (e.g., copper, aluminum, titanium, gold, etc.), alloy materials (e.g., aluminum alloy, titanium alloy, etc.), plastic materials (e.g., polyethylene, polypropylene, epoxy resin, nylon, etc.), fiber materials (e.g., acetate fiber, propionate fiber, carbon fiber, etc.), etc. In some embodiments, a protective sheath can be provided on the outside of the support assembly 110. The protective sheath can be made of a soft material with a certain degree of elasticity, such as soft silicone or rubber, to provide a good tactile feel when worn by the user.

[0047] The movement module 120 may include a sound pickup assembly. The sound pickup assembly can be used to pick up sound (i.e., mechanical vibration signals) through the communication holes on the surface of the housing and convert the picked up sound into an audio signal (e.g., an electrical signal). In some embodiments, the acoustic device 100 can transmit the audio signal to other acoustic devices, such as speakers, loudspeakers, etc. In some embodiments, the acoustic device 100 can transmit the audio signal to other components in the acoustic device 100. For example, the movement module 120 may also include a speaker assembly so that the audio signal is converted into a mechanical vibration signal by the speaker assembly and transmitted to the auditory nerve through the wearer's bones, etc., to achieve a hearing aid function. In some embodiments, the speaker assembly can be physically connected to other components of the acoustic device 100, such as the support assembly 110 and the sound pickup assembly. By way of example only, the physical connection may include injection molding, welding, riveting, bolting, bonding, snap-on connection, etc., or any combination thereof. In some embodiments, the sound pickup assembly may include one or more microphones (e.g., a microphone array). In some embodiments, the acoustic device 100 may include multiple sound pickup assemblies. Each sound pickup assembly may correspond to a communication hole. Multiple sound pickup components can be spaced apart and arranged in the housing. For more information on the arrangement positions of the multiple sound pickup components, please refer to other places in this application (for example, Figure 2 and Figure 7 and its description).

[0048] The channel member 130 may be disposed in the accommodating space. In some embodiments, the channel member 130 may be disposed between the pickup assembly and the connecting hole, so that the sound is transmitted to the pickup assembly through the channel member 130 after passing through the connecting hole. In some embodiments, at least one of the one or more pickup assemblies may correspond to a channel member 130, so as to improve the sound pickup effect of the corresponding pickup assembly. In some embodiments, the channel member 130 may include a first hole (also referred to as a sound inlet hole), a channel, and a second hole (also referred to as a sound outlet hole). In some embodiments, the first hole and the connecting hole may be connected to each other, and the second hole may be disposed adjacent to the pickup assembly so that the sound is transmitted to the pickup assembly through the connecting hole, the first hole, the channel, and the second hole in sequence. For more descriptions of the channel member, please refer to other places in this application (such as Figures 6A-6B and its related descriptions).

[0049] In some embodiments, the acoustic device 100 may further include a control circuit component and one or more interactive components (not shown in the figure). The control circuit component can be used to control the acoustic device 100, such as volume control, power on / off control, operating mode selection (for example, play / pause), wireless connection or data transmission control, etc. In some embodiments, the control circuit component may include multiple control elements. Each control element may correspond to at least one speaker component among a plurality of speaker components. Each interactive component may correspond to each speaker component and its corresponding control element. Each interactive component can be used to receive user operation instructions, trigger the control element corresponding to the interactive component to control the corresponding speaker component to implement the function corresponding to the user operation instruction. For more description of the control circuit component and the interactive component, please refer to other places in this application (such as Figure 8 and 9 and its related descriptions).

[0050] In some embodiments, the acoustic device 100 may further include a protective component (not shown). In some embodiments, the protective component may have the function of protecting the acoustic device 100, for example, waterproof and dustproof functions. In some embodiments, the protective component may be disposed in the support component 110 and physically connected to the support component to form a protective barrier for protecting the acoustic device 100. For example, the movement module 120 may be disposed in the accommodation space inside the shell of the support component 110, and the protective component may be disposed between the movement module 120 and the shell of the support component 110 to form a protective barrier for protecting the movement module 120, thereby achieving functions such as waterproof and dustproof functions.

[0051] It should be noted that the above description of the acoustic device 100 is intended to illustrate, not to limit the scope of this application. Many alternatives, modifications and variations will be apparent to those of ordinary skill in the art. The features, structures, methods and other features of the exemplary embodiments described herein may be combined in various ways to obtain additional and / or alternative exemplary embodiments. In some embodiments, the acoustic device 100 may further include a battery assembly, a Bluetooth assembly, etc., or a combination thereof. The battery assembly may be used to power the acoustic device 100. The Bluetooth assembly may be used to wirelessly connect the acoustic device 100 to other devices (e.g., mobile phones, computers, etc.).

[0052] Figure 2 Schematic diagram of an exemplary acoustic device according to some embodiments of the present application. Figure 2 As shown, acoustic device 200 may include a support assembly 210 , one or more pickup assemblies (e.g., pickup assemblies 222 , 224 , and 226 ), two speaker assemblies (e.g., speaker assemblies 232 and 234 ), a battery assembly 240 , and a control circuit assembly 250 .

[0053] The support assembly 210 may include a first portion 212 (i.e., earhook assembly 212), a second portion 214 (i.e., earhook assembly 214), and a third portion 216 (i.e., rear-hook assembly 216). The two ends of the rear-hook assembly 216 may be connected to one end of the two earhook assemblies (i.e., earhook assembly 212 and earhook assembly 214), respectively. When the user wears the acoustic device 200, the earhook assembly 212 and the earhook assembly 214 may be respectively hung on the user's ears, and the rear-hook assembly 216 may be wrapped around the back of the user's head or neck so that the acoustic device 200 can be worn stably.

[0054] In some embodiments, the speaker assemblies 232 and 234 can be used to convert audio signals (e.g., electrical signals) into mechanical vibrations of different frequencies. Two speaker assemblies (i.e., speaker assemblies 232 and 234) can be arranged at the other end of the two ear hook assemblies. For example, the ear hook assembly 212 and the ear hook assembly 214 can respectively include a housing space, the speaker assembly 232 can be arranged in the housing space of the ear hook assembly 212, and the speaker assembly 234 can be arranged in the housing space of the ear hook assembly 214. When the acoustic device 200 is worn, the two speaker assemblies can transmit mechanical vibrations to the human auditory system through the wearer's bones and / or cochlea, so that the wearer can hear the sound. In some embodiments, the speaker assemblies 232 and / or 234 can exist independently of the ear hook assembly. That is, the speaker assemblies 232 and / or 234 can include a speaker housing. The speaker housing can be connected to the ear hook assembly 212 and / or 214, and the speaker assembly can be arranged outside the ear hook assembly 212 and the ear hook assembly 214. For more descriptions about the ear hook assembly, please refer to Figure 3-4 Detailed description.

[0055] In some embodiments, one or more components of the acoustic device 200 may be disposed within the housing space formed by the support assembly 210. For example, Figure 2 As shown, the battery assembly 240 can be arranged in the accommodation space within the ear hook assembly 212. The control circuit assembly 250 can be arranged in the accommodation space within the ear hook assembly 214. For another example, the battery assembly 240 and / or the control circuit assembly 250 can be arranged in the rear hanging assembly 216. For another example, the acoustic device 200 can also include a Bluetooth assembly. The Bluetooth assembly can be arranged in the accommodation space within the rear hanging assembly 216. For another example, the acoustic device 200 can also include one or more channel members. At least one of the one or more channel members can be arranged between at least one of the one or more pickup assemblies and one of the one or more connecting holes on the support assembly 210. For more descriptions of the channel members, please refer to the description elsewhere in this application (for example, Figures 6A-6B Detailed description in ).

[0056] In some embodiments, the acoustic device 200 may include multiple sound pickup assemblies, for example, 2, 3, 4, 5, etc. Each sound pickup assembly may be positioned near a communication hole on the support assembly 210 so that the sound pickup assembly can pick up sound through the corresponding communication hole. The multiple sound pickup assemblies may be independent of each other and may independently perform sound pickup and signal amplification, thereby independently picking up and processing sounds from different directions, allowing the wearer (e.g., a hearing-impaired person) to adapt to sounds from different directions and improve the wearer's hearing experience. In some embodiments, the multiple sound pickup assemblies may be spaced apart at different positions on the support assembly 210. For example, the multiple sound pickup assemblies may be spaced apart within the rear hanging assembly 216 (e.g., positions F, G, H, and I). For another example, one of the multiple sound pickup assemblies may be positioned in the middle position (i.e., position I) of the rear hanging assembly 216, and the remaining sound pickup assemblies may be spaced apart on one side or both sides of the middle position. For another example, the multiple sound pickup assemblies may be spaced apart within the ear hook assemblies 212 and / or 214. For another example, some of the multiple sound pickup components can be spaced apart in the ear hook component (for example, Figure 2 Middle positions E and B and / or Figure 4 The remaining pickup assemblies may be spaced apart within the rear mounting assembly 216. In some embodiments, when the speaker assembly exists independently, the plurality of pickup assemblies may also be disposed within the speaker housing. In some embodiments, a portion of the plurality of pickup assemblies may be spaced apart within the support assembly 210, while the remaining portion may be spaced apart within the speaker housing. In some embodiments, the location of a pickup assembly may also be referred to as the location of its corresponding communication hole.

[0057] It should be noted that, since the sound pickup component is mainly used to pick up the user's voice, the ambient sound of the user's environment, etc., therefore, for the wearer (for example, the hearing-impaired), the sound pickup effect of the sound pickup component will affect the clarity and stability of the sound received by the wearer through the acoustic device 200. In general, the sound pickup component can be set at any position on the acoustic device 200. However, the closer the sound pickup component is to the speaker component, the more easily it is affected by the speaker component, and the more likely it is to cause "howling" due to the acoustic coupling between the two. Therefore, the setting position of the sound pickup component can be determined according to the requirements for the howling threshold of the acoustic device 200. For more information on the relationship between the howling threshold of the sound pickup component and its relative position on the acoustic device, please refer to other places in this application (such as Figure 7 and its description).

[0059] In some embodiments, the ear hook housing 310, the connecting component 320 and / or the speaker housing 330 can be integrally formed. For example, the connecting component 320 can be connected to the ear hook housing 310 and the speaker housing 330 by injection molding. In some embodiments, the ear hook housing 310, the connecting component 320 and / or the speaker housing 330 can be connected by a connecting structure to form a foldable ear hook assembly. Exemplary connecting structures may include a snap-on structure, a plug-in structure, a hinge structure, or the like, or a combination thereof.

The housing space 360 ​​may accommodate one or more of a battery assembly, a control circuit assembly, a pickup assembly, a channel member, a Bluetooth assembly, and the like. By way of example only, the housing space 360 ​​may accommodate the pickup assembly 340. In some embodiments, the second earhook housing 314 may be physically connected to the connecting component 320. For example, the second earhook housing 314 may be fixedly connected to one end of the connecting component 320 by injection molding. For another example, the second earhook housing 314 may be connected to one end of the connecting component 320 by welding, riveting, bonding, or snapping. In some embodiments, the first earhook housing 312 may be physically connected to the second earhook housing 314. For example, the first earhook housing 312 may be connected to the second earhook housing 314 by welding, riveting, bonding, or snapping. In some embodiments, the first ear hook housing 312 and the second ear hook housing 314 can be physically connected to the connecting component 320. For example, the first ear hook housing 312 and the second ear hook housing 314 can be connected to one end of the connecting component 320 by injection molding.

[0061] In some embodiments, a receiving groove (such as a groove) for receiving the pickup assembly 340 may be provided in the receiving space 360. Figure 5accommodating slot 525 in). In some embodiments, a connecting hole 350 is provided on the ear hook shell 310 to connect the accommodating space 360 ​​and the outside world. The sound pickup assembly 340 can be arranged in the accommodating space 360 ​​and adjacent to the connecting hole 350, so that the sound pickup assembly 340 can pick up sound through the connecting hole 350. In some embodiments, the distance between the sound pickup assembly 340 and the connecting hole 350 may be not less than 1 mm. For example, the distance between the sound pickup assembly 340 and the connecting hole 350 may be 1 mm, 2 mm, 3 mm, 5 mm, 7 mm, 10 mm, etc. In some embodiments, the connecting hole 350 may be provided on the first ear hook shell 312 of the ear hook shell 310. For more descriptions about the first ear hook shell 312, please refer to other places in this application (for example, Figure 5 and its description).

[0062] Usually, the speaker assembly may cause the outside air to vibrate during the process of sound production, which is the phenomenon of "sound leakage". Therefore, the connecting hole 350 can be opened on the side of the ear hook shell 310 away from the speaker assembly (located in the speaker shell 330) (such as position C) or away from the side of the connecting part 320 (such as position D), so as to avoid the "sound leakage" caused by the sound pickup assembly 340 picking up the speaker assembly as much as possible, thereby reducing the interference of the speaker assembly on the sound pickup assembly 340. In addition, the sound pickup assembly 340 is arranged on the side away from the speaker assembly in the accommodating space 360, which can also reduce the mechanical vibration generated by the speaker assembly from being transmitted to the sound pickup assembly 340, thereby reducing the occurrence of "howling" or noise generated by the sound pickup assembly 340. It should be noted that in some embodiments, the position of the connecting hole 350 can also be referred to as the position of its corresponding sound pickup assembly. In some embodiments, the connecting hole 350 can also be opened at other positions of the ear hook shell 310. For example, the communication hole 350 may be provided on the side of the ear hook housing 310 facing the speaker assembly, or on the side of the acoustic device (or ear hook assembly 300) facing the user's head when worn, or on the side of the acoustic device (or ear hook assembly 300) facing away from the user's head when worn (e.g., position O). For another example, the communication hole 350 may be provided at positions B, D, or E on the first ear hook housing 312.

[0063] In some embodiments, as Figure 4As shown, the connecting component 320 may include a first elastic coating 321, a second elastic coating 322 and an elastic support member 323. One end of the elastic support member 323 can be connected to the ear hook housing 310 (for example, the second ear hook housing 314), and the other end of the elastic support member 323 can be connected to the speaker housing 330 (or speaker assembly). In some embodiments, a wire (not shown) can be provided in the connecting component 320. One end of the wire can be electrically connected to the pickup assembly 340, the battery assembly, the control circuit assembly, etc. provided in the accommodating space 360, and the other end of the wire can be electrically connected to the speaker assembly in the speaker housing 330.

[0064] In some embodiments, the first elastic coating 321 and the second elastic coating 322 can be formed by injection molding (for example, two-color injection molding) and wrap the elastic support member 323 and the wire. In some embodiments, the elastic support member 323 can wrap the wire. In some embodiments, the elastic support member 323 can be curved and have a certain rigidity / strength to form the basic form of the ear hook assembly 300, thereby making it easier for the user to wear the acoustic device. The first elastic coating 321 and the second elastic coating 322 can protect the elastic support member 323 and the wire they wrap. In some embodiments, the first elastic coating 321 and the second elastic coating 322 can be made of a soft material with a certain elasticity, such as soft silicone, rubber, fiber, etc., to provide a better touch for the user to wear. In some embodiments, the joint seam of the first elastic coating 321 and the second elastic coating 322 can divide the surface of the connecting part 320 into an inner side and an outer side that are arranged opposite to each other. The exposed surface of the first elastic coating 321 can serve as the inner surface of the connecting component 320, and the exposed surface of the second elastic coating 322 can serve as the outer surface of the connecting component 320. It should be noted that when the acoustic device (or earhook assembly 300) is worn, the inner surface of the connecting component 320 is closer to the wearer's skin than the outer surface. The inner surface of the connecting component 320 mostly contacts the user's ear and the surrounding head.

[0065] In some embodiments, when making the connecting component 320, an auxiliary metal wire can be used. The auxiliary metal wire can be arranged side by side with the elastic support member 323. In some embodiments, the auxiliary metal wire and the elastic support member 323 can have substantially the same structural parameters such as shape, length, and radius of curvature. In some embodiments, the diameter of the auxiliary metal wire can be less than or equal to the diameter of the wire. Furthermore, an elastic coating can be formed on the surface of the auxiliary metal wire and the elastic support member 323 by injection molding, and then the auxiliary metal wire can be pulled out to obtain the connecting component 320. Finally, when making the acoustic device, the wire can be passed through the elastic coating (that is, the position where the auxiliary metal wire was originally located). However, during the above-mentioned injection molding process, since the auxiliary metal wire and the elastic support member 323 have a certain length and radius of curvature, the two (especially the middle area therebetween) may deviate from their original position under the impact of the injection molding material, ultimately resulting in uneven wall thickness of the elastic coating, affecting the molding quality of the connecting component 320. Especially when the elastic covering is designed to have a thin wall thickness, the connecting component 320 may be "broken" during long-term use of the acoustic device, thereby affecting the user experience.

[0066] In some embodiments, the elastic coating can be divided into a first elastic coating 321 and a second elastic coating 322. The first elastic coating 321 and the second elastic coating 322 can be injection molded in two steps. Specifically, a through groove 324 can be formed on one side of one of the elastic coatings (for example, the first elastic coating 321). The through groove 324 can be extended along the extension direction of the first elastic coating 321 and can be used to place the elastic support 323 and the auxiliary metal wire. Furthermore, the second elastic coating 322 can be injection molded on the side of the through groove 324 of the first elastic coating 321, and cover the elastic support 323 and the auxiliary metal wire, so that after the first elastic coating 321 and the second elastic coating 322 are spliced ​​and fixed, by pulling out the auxiliary metal wire, a lead channel ( Figure 4 (not marked in the figure). The lead channel can be used to pass wires. It should be noted that because the through groove 324 has a certain depth, the first elastic coating 321 can partially wrap the elastic support member 323 and the auxiliary metal wire, thereby limiting them. This allows the elastic support member 323 and the auxiliary metal wire to withstand the impact of the injection molding material, which helps to improve the problem of the elastic support member 323 and the auxiliary metal wire deviating from their original position.

[0067] In some embodiments, the depth of the through-slot 324 can be equal to the radius of the larger diameter of the elastic support member 323 or the auxiliary wire. In some embodiments, the depth of the through-slot 324 can be greater than the radius of the smaller diameter of the elastic support member 323 or the auxiliary wire, and less than the radius of the larger diameter of the elastic support member 323 or the auxiliary wire. In some embodiments, the depth of the through-slot 324 can be greater than the radius of the larger diameter of the elastic support member 323 or the auxiliary wire. In some embodiments, there can be two through-slots 324. Two through-slots 324 can be arranged side by side and used to accommodate the elastic support member 323 and the auxiliary wire, respectively, so that the lead channel and the elastic support member 323 are separated from each other, thereby preventing interference between the elastic support member 323 and the auxiliary wire (or conductor). In some embodiments, there can be only one through-slot 324, and the elastic support member 323 and the auxiliary wire can be accommodated together in the through-slot 324, so that the elastic support member 323 is exposed to the lead channel, thereby simplifying the structure of the connecting component 320.

[0068] In some embodiments, the ear hook shell 310 (for example, the second ear hook shell 314) can be connected to one end of the connecting part 320 (for example, the elastic support member 323) by injection molding. Furthermore, the second elastic coating 322 can be connected to the third elastic coating 316 that covers at least part of the outer surface of the ear hook shell 310 by injection molding. The first elastic coating 321 can be located between the ear hook shell 310 and the speaker shell 330 and does not cover the outer surface of the ear hook shell 310. For example, the second elastic coating 322 can cover the outer surface of the first ear hook shell 312, that is, the third elastic coating 316 and the second elastic coating 322 are the same coating, and the first elastic coating 321 can be located between the first ear hook shell 312 and the speaker shell 330 and does not cover the outer surface of the first ear hook shell 312.

[0069] In some embodiments, the molding process of the ear hook assembly 300 may include the following operations: operation 1) forming a speaker shell 330 and a second ear hook shell 314 at both ends of the elastic support member 323; operation 2) obtaining a first elastic coating 321 having a through groove 324 by a first injection molding method; operation 3) assembling the first elastic coating 321 obtained in operation 2) with the semi-finished product and the auxiliary metal wire in operation 1); operation 4) forming a second elastic coating 321 at the location of the through groove 324 by a second injection molding method. A second elastic coating 322 is formed on one side, and a third elastic coating 316 is formed on one side of the outer surface of the second ear hook shell 314 to wrap the elastic support 323 and the auxiliary metal wire, and cover the outer surface of the second ear hook shell 314; operation 5) extracts the semi-finished auxiliary metal wire obtained in operation 4) to form a lead channel, and then passes the wire through the lead channel; operation 6) fixes the first ear hook shell 312 and the second ear hook shell 314 in operation 5) by one of the methods such as gluing, clamping, and threaded connection or a combination thereof.

[0070] It should be noted that the acoustic device may include two earhook assemblies 300, and the number of sound pickup assemblies 340 and the number of channel members may also be two. Specifically, the accommodation space 360 ​​of each earhook assembly 300 may be provided with a sound pickup assembly 340 and a channel member, so as to improve the sound pickup effect of each sound pickup assembly 340.

[0071] Figure 5 yes Figure 4 Schematic diagram of the structure of the first ear hook shell. Figure 5 As shown, the first ear hook shell 312 may include a bottom wall 3122 and a side wall 3124 connected to the bottom wall 3122. The second ear hook shell 314 may cover the side wall 3124 and be arranged opposite to the bottom wall 3122 to form an accommodating space 360. In some embodiments, a receiving groove 525 for accommodating the pickup assembly 340 may be provided in the accommodating space 360. In some embodiments, a flange 3126 may be provided on a side of the bottom wall 3122 facing the second ear hook shell 314. The flange 3126 may enclose the accommodating groove 525 to limit and fix the pickup assembly 340. In some embodiments, the flange 3126 and at least a portion of the side wall 3124 may together enclose the accommodating groove 525.

[0072] In some embodiments, a communication hole 350 may be provided on the first ear hook housing 312. In some embodiments, in order to minimize the interference of the speaker assembly with the pickup assembly, the communication hole 350 may be provided on the side wall 3124 away from the speaker assembly (e.g., Figure 4 In some embodiments, the communication hole 350 may also be formed on the bottom wall 3122.

[0073] It should be noted that if the sound pickup component 340 is directly connected to the outside world through the connecting hole 350, the sound path between the sound pickup component 340 and the outside world (which can also be simply referred to as the sound path of the sound pickup component 340) will be shorter. When the acoustic device is in a complex environment (for example, when the air flow is relatively intense), the sound pickup component 340 picks up more noise, thereby causing the "wind noise" phenomenon. The "wind noise" phenomenon may refer to the phenomenon that the sound pickup component 340 picks up external noise and generates noise. Therefore, according to some embodiments of the present application, a channel member (such as a channel member) may be provided between the sound pickup component 340 and the connecting hole 350. Figure 6A The channel piece 600 shown in the figure) is used to extend the sound path of the sound pickup assembly 340, thereby improving the sound pickup effect of the sound pickup assembly 340. In some embodiments, the channel piece may include a first hole (also referred to as a sound inlet hole), a channel, and a second hole (also referred to as a sound outlet hole). In some embodiments, the channel piece may be disposed in the accommodating space 360 ​​and covered on the flange 3126. In other words, the channel piece may cover the accommodating groove 525 and press the sound pickup assembly 340 in the accommodating groove 525, with the sound inlet hole facing the side wall 3124 and docking and communicating with the connecting hole 350, and the sound outlet hole docking and communicating with the sound pickup assembly 340. With this arrangement, the channel piece not only extends the sound path of the sound pickup assembly, but also achieves the fixation of the sound pickup assembly. For more descriptions of the channel piece, please refer to other places in this application (for example, Figure 6A and its description).

[0074] In some embodiments, the communication hole 350 can be a gap with a certain width (e.g., 0.2 mm, 0.5 mm, 1 mm, etc.) to increase the contact area between the sound path of the pickup assembly 340 and the outside world, thereby improving the sound pickup effect of the pickup assembly 340. In some embodiments, the shape of the communication hole 350 can be circular, square, oval, triangular, etc. In some embodiments, to prevent the excessive contact area between the sound path of the pickup assembly 340 and the outside world from reducing the waterproof and dustproof performance of the earhook housing 310 and / or causing "wind noise", a protective member 540 can be provided in the sound path of the pickup assembly 340. By way of example only, the protective member 540 can be provided between the channel member and the earhook housing 310, thereby separating the communication hole 350 from the sound inlet of the channel member, thereby enhancing the windproof and noise reduction capabilities of the pickup assembly 340 and improving the waterproof and dustproof performance of the earhook assembly 300. In some embodiments, the protective member 540 can include one or more stacked meshes, such as a first mesh 542 and a second mesh 544. In some embodiments, one or more nets may be made of different or the same materials. In some embodiments, the first net 542 may include a metal net (e.g., an iron net, an aluminum net) and the second net 544 may include a non-metallic net (e.g., a nylon net, a cotton and linen net). In some embodiments, the second net 544 is closer to the channel member than the first net 542. In some embodiments, the structural strength of the first net 542 may be greater than the structural strength of the second net 544. In some embodiments, the mesh number of the second net 544 may be greater than the mesh number of the first net 542, and the two cooperate to enable the protective member 540 to take into account its own structural strength, the sound pickup requirements of the sound pickup assembly 340, and the waterproof and dustproof requirements of the ear hook assembly 300.

[0075] In some embodiments, a volume button hole 550 and / or a function key hole 555 may be further provided on the first ear hook shell 312. The volume button may be provided in the volume button hole 550 and exposed through the volume button hole 550, so that the user can control the corresponding processing chip on the circuit board of the acoustic device by pressing / swiping the volume button, thereby adjusting the audio gain of the speaker assembly of the acoustic device. Similarly, the function key may be provided in the function key hole 555 and exposed through the function key hole 555, so that the user can control the corresponding processing chip on the circuit board of the acoustic device by pressing / swiping the function key, thereby adjusting the corresponding function of the acoustic device. In some embodiments, the functions controlled by the function key may include controlling power on / off, controlling pause / play, controlling wireless connection or data transmission, etc., or any combination thereof.

[0076] Figure 6A It is a schematic structural diagram of a channel member according to some embodiments of the present application. Figure 6B yes Figure 3 Schematic diagram of the structure of the pickup component. Figure 6AAs shown, the channel member 600 may include a first hole 610 (also referred to as a sound inlet hole), a channel 620, and a second hole 630 (also referred to as a sound outlet hole). The sound inlet hole 610 and the sound outlet hole 630 may be spaced apart and connected to the channel 620. The sound inlet hole 610 may be connected to a communication hole on the earhook assembly (e.g., the communication hole 350 on the earhook assembly 300). The sound outlet hole 630 may be located adjacent to the sound pickup assembly 340 so that sound can be transmitted to the sound pickup assembly 340 in sequence through the communication hole, the sound inlet hole 610, the channel 620, and the sound outlet hole 630.

[0077] In some embodiments, the shape of the sound inlet 610 can be the same as or similar to that of the communication hole. For example, when the communication hole is a slit with a certain width, the sound inlet 610 can be configured as a slit. For another example, when the communication hole is configured as a circular hole, the sound inlet 610 can be configured as an elliptical hole or a circular hole.

[0078] In some embodiments, the channel 620 may include a channel top wall 640, a channel bottom wall 650, and a channel sidewall 660. The channel top wall 640 and the channel bottom wall 650 may be located at opposite ends of the channel sidewall 660, respectively. Specifically, the channel top wall 640 and the channel bottom wall 650 may be disposed opposite each other, and the channel sidewall 660 may be connected between the channel top wall 640 and the channel bottom wall 650. In some embodiments, the length of the channel 620 along the direction connecting the channel top wall 640 and the channel bottom wall 650 may range from 0.45 to 0.75 mm. For example, the length of the channel 620 along the direction connecting the channel top wall 640 and the channel bottom wall 650 may be 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, etc. In some embodiments, when the channel member 600 presses against the pickup assembly 340, specifically, the channel bottom wall 650 may press against the pickup assembly 340. As an example, the channel top wall 640 and the channel bottom wall 650 are arranged in parallel and spaced apart, so that the channel 620 is arranged in a flat shape to adapt to the flat structure of the shell.

[0079] In some embodiments, the sound inlet 610 can be provided in the channel sidewall 660 or the channel top wall 640, and the sound outlet 630 can be provided in the channel bottom wall 650. In some embodiments, the distance between the sound inlet 610 and the sound outlet 630 along the channel 620 can be greater than or equal to 4 mm to extend the sound path of the pickup assembly 340. For example, the distance between the sound inlet 610 and the sound outlet 630 along the channel 620 can be 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 8 mm, 10 mm, etc. In some embodiments, the channel member 600 can be a tubular structure with both ends open, consisting only of sidewalls. One end of the tubular structure can be the sound inlet, and the other end can be the sound outlet.

[0080] In some embodiments, as Figure 6B As shown, the pickup assembly 340 may include a pickup element 342 and a protective cover 344. The protective cover 344 may be disposed around the periphery of the pickup element 342. In some embodiments, the protective cover 344 may define a groove 346 facing the channel bottom wall 650, with the pickup element 342 at least partially located in the groove 346. This configuration allows the protective cover 344 to abut against and fit against the sidewalls (e.g., flange 3126) of the receiving slot 525 when the channel member 600 (e.g., the channel bottom wall 650 of the channel member 600) holds the pickup assembly 340 within the receiving slot 525 (i.e., when the channel member 600 is disposed over the pickup assembly 340). The groove 346 and the sound outlet 630 may be in contact and in communication with each other, allowing the picked-up sound to enter the pickup element 342 through the sound outlet 630 and the groove 346. It should be noted that, in this application, the abutment between the protective cover 344 and the sidewalls of the receiving groove 525 refers to the presence of a force between the protective cover 344 and the sidewalls of the receiving groove, thereby allowing the protective cover 344 and the sidewalls of the receiving groove to fit tightly together. In some embodiments, the protective cover 344 can be elastic (e.g., a silicone cover) so that during assembly of the acoustic device, the protective cover 344 can elastically deform, thereby increasing the securing effect of the sidewalls of the receiving groove on the pickup assembly 340 and enhancing the sealing of the sound path between the pickup assembly 340 and the channel member 600, thereby improving the sound pickup performance of the pickup assembly 340. In some embodiments, the protective cover 344 and the pickup element 342 can fit tightly together, and the pickup portion (e.g., the diaphragm) of the pickup element 342 can be exposed in the groove 346. This prevents sound from leaking from between the protective cover 344 and the pickup element 342 to the rear side of the pickup element 342 after transmitting to the groove 346, thereby effectively maintaining the sound pickup performance of the pickup element 342.

[0081] Figure 7 : is a diagram showing the relationship between the howling threshold of the pickup assembly and its position in the acoustic device according to some embodiments of the present application. Figure 7 As shown in the figure, the horizontal axis can represent the position of the sound pickup component (or the connecting hole corresponding to the sound pickup component) in the acoustic device, and the vertical axis can represent the howling threshold of the sound pickup component (in dB). It should be noted that the larger the howling threshold of the sound pickup component, the lower the probability of the sound pickup component experiencing "howling" and the less it is affected by the speaker component.

[0082] exist Figure 7 In the figure, positions O, B, C, D, E, F, G, H and I indicate that the pickup components are respectively located at Figure 2 and Figure 4 Positions O, B, C, D, E, F, G, H and I. Figure 4 The ear hook assembly 300 in Figure 2212 and / or 214 of the acoustic device. Figure 2 and 4 As shown, when the acoustic device is in the wearing state, position O is located on the outside of the ear hook assembly 300 away from the user's head, positions B and E are located above the ear hook shell 310 of the ear hook assembly 300, and position E is further away from the speaker assembly than position B, position D is located below the ear hook shell 310, and position C is located at the rear of the ear hook shell 310 away from the speaker assembly. Figure 2 , positions F, G, H, and I are sequentially away from the speaker assembly 232 and / or 234. Among them, position I can correspond to the middle position of the rear hanging assembly 216.

[0083] The howling threshold corresponding to position O can be used as a reference threshold, that is, the howling threshold of position O is defined as 0. Figure 7 As shown, the howling thresholds of positions B, C, D, E, F, G, H, and I are all greater than 0, which means that the sound pickup components set at these positions are conducive to improving the "howling" phenomenon. Furthermore, the howling thresholds of positions F, G, H, and I are significantly higher than those of positions B, C, D, and E, which means that the sound pickup component set on the rear-hanging component is more conducive to improving the "howling" phenomenon. It is worth noting that for the earhook shell, the howling thresholds of positions C and E are also significantly higher than those of positions B and D, which means that the further the sound pickup component is set on the earhook shell away from the speaker component, the more conducive it is to improving the "howling" phenomenon. For position E, there may be structural interference between the earhook component and the rear-hanging component, so it is preferred to set the sound pickup component at position C on the earhook component.

[0084] Figure 8 1 is a block diagram of an exemplary acoustic device according to some embodiments of the present application. Figure 8 As shown, the acoustic device 800 may include a plurality of speaker assemblies 810 (eg, speaker assemblies 810 - 1 , 810 - 2 ), a control circuit assembly 820 , and a plurality of interaction assemblies 830 (eg, interaction assemblies 830 - 1 , 830 - 2 ).

[0085] The speaker assembly 810 can be used to convert an audio signal (e.g., an electrical signal) into a mechanical vibration signal. For example, the speaker assembly 810 can receive an audio signal from a microphone, a mobile phone, an MP3 player, etc., and convert it into a mechanical vibration signal, thereby producing sound. In some embodiments, the speaker assembly 810 may include a bone conduction speaker, an air conduction speaker, or a combination thereof. By way of example only, the speaker assembly 810 may be a bone conduction speaker. A bone conduction speaker may include a magnetic circuit assembly, a vibration assembly, and a speaker housing. The magnetic circuit assembly can be used to provide a magnetic field. Upon receiving an audio signal, the vibration assembly can convert the audio signal into a mechanical vibration signal under the influence of the magnetic field. For example, the vibration assembly may include a voice coil and a vibrating plate. The voice coil is disposed in a magnetic gap formed by the magnetic circuit assembly. When the speaker assembly 810 receives an electrical signal (i.e., an audio signal), the voice coil vibrates under the influence of the magnetic field. The voice coil is physically connected to the vibrating plate and transmits the vibration to the vibrating plate. The speaker housing may include a vibration panel (i.e., a vibration transmission plate) facing the user's body. The speaker housing may accommodate the vibration assembly. In some embodiments, the vibration component can be physically connected to the vibration panel to cause the vibration panel to vibrate so as to be transmitted to the user's auditory nerve through the user's head, thereby allowing the user to hear the sound.

[0086] In some embodiments, the speaker assembly 810 can provide various resonance peaks. For example, the speaker assembly 810 can provide a low-frequency resonance peak below 500 Hz, a low-frequency resonance peak below 1000 Hz, or a high-frequency resonance peak above 5000 Hz. In some embodiments, the speaker assembly 810 can include various types, such as electromagnetic (e.g., moving coil, moving iron, etc.), piezoelectric, inverse piezoelectric, electrostatic, etc., which are not limited in this application.

[0087] The control circuit component 820 can be used to control other components of the acoustic device 800 (for example, the speaker component 810) to achieve one or more functions of the acoustic device 800. In some embodiments, the control circuit component 820 may include multiple control elements (for example, control elements 820-1, 820-2, etc.). Each control element can control at least one speaker component to independently control the speaker component, for example, independently control the audio gain of the corresponding speaker component. In some embodiments, the control circuit component 820 may also include one or more function buttons to control the power on / off, pause / play, wireless connection / disconnection, etc. of the acoustic device 800. For more descriptions of the control circuit component, please refer to other places in this application (for example, Figure 9 and its description).

[0088] The interactive component 830 can be used to enable interaction between a user and the acoustic device 800. For example, the interactive component 830 can be used to enable interaction between a user and the speaker component 810 and the control circuit component 820. Furthermore, in response to receiving a user operation instruction, the interactive component 830 can trigger the control circuit component 820 to control the acoustic device 800 to implement the function corresponding to the user operation instruction. For example, in response to receiving a user press instruction, the interactive component 830 can control the control circuit component 820 to turn the acoustic device 800 on and off. For another example, each interactive component can correspond to a speaker component and its corresponding control element. Furthermore, each interactive component can be used to trigger the control element in the control circuit component 820 to control the corresponding speaker component 810 to implement the function corresponding to the user operation instruction in response to receiving a user operation instruction. For example, the interactive component 830-1 can control the control element 820-1 to increase or decrease the audio gain of the speaker component 810-1 in response to receiving a user press or dial instruction.

[0089] In some embodiments, the interactive component 830 may include one or more third holes provided on the support component (e.g., ear hook component) of the acoustic device 800 and first components respectively provided in the third holes, for triggering the control circuit component 820 (e.g., control element) to control one or more functions of the acoustic device 800. The first component may be used to receive user operation instructions. In some embodiments, the user instruction may be in the form of force, sound, or the like. For example, a user may generate a user operation instruction by pressing, stroking, or the like. As another example, the first component may be a sound sensor that receives user sound to generate the user operation instruction. In some embodiments, the first component may include one or more buttons, such as a volume button and a function button. In some embodiments, the control circuit component 820 (e.g., each control element) may include a second component. In response to a user operation instruction (e.g., a press, a touch) received by the first component, the second component may trigger the control circuit component 820 to implement the function corresponding to the operation instruction, such as volume increase / decrease, play / pause, power on / off, etc. In some embodiments, the second component may include a function switch, such as a mechanical switch or a voice-activated switch. For example, a switch receiving area may be provided on one side of the first component. The switch accommodation area can be used to accommodate a function switch, so that when the first component receives an operation instruction from the user (e.g., a toggle), the function switch is toggled, thereby triggering the control unit in the control circuit assembly 820 to implement the function corresponding to the instruction. For another example, the second component can trigger the function switch in response to a sound of a certain intensity to implement the function corresponding to the second component.

Figure 9 As shown, the acoustic device 900 may include a speaker assembly 910, a speaker assembly 920, an ear hook assembly 930, an ear hook assembly 940 and a rear hanging assembly 950. It should be noted that a part of the shell and the various components contained in its corresponding accommodation space can be collectively referred to as a shell assembly. Specifically, an ear hook assembly 930 and 940 and a corresponding speaker assembly 910 and 920 can be respectively provided at both ends of the rear hanging assembly 950. In some embodiments, the various electrical devices (such as a pickup assembly, a speaker assembly, etc.) at both ends of the rear hanging assembly 950 can be electrically connected through wires built into the rear hanging assembly 950 to realize the transmission of control instructions, electrical energy, etc.

[0091] In some embodiments, the earhook assembly 930 may include a main circuit board 932, a volume button 934, a function button 936, a sound pickup assembly 938, or any combination thereof. The earhook assembly 940 may include a secondary circuit board 942, a volume button 944, a battery assembly 946, a sound pickup assembly 948, or any combination thereof. In some embodiments, the main circuit board 932 may be accommodated within the housing space of the earhook assembly 930, and the battery assembly 946 may be accommodated within the housing space of the earhook assembly 940 to facilitate balanced weight distribution of the acoustic device 900.

[0092] In some embodiments, the main circuit board 932 may be integrated with two independent audio processing chips (also referred to as control elements) to independently control the audio gain of the two speaker assemblies 910 and 920. In some embodiments, the main circuit board 932 may be integrated with an audio processing chip for controlling the speaker assembly 910 to independently control the audio gain of the speaker assembly 910, and the auxiliary circuit board 942 may be integrated with an audio processing chip for controlling the speaker assembly 920 to independently control the audio gain of the speaker assembly 920. By way of example only, the audio processing chip may be a digital signal processing (DSP) chip.

[0093] In some embodiments, a user can control the two speaker assemblies 910 and 920 respectively using two volume buttons 934 and 944. For example, a volume button hole connected to the accommodating space can be formed on the earhook housing corresponding to each earhook assembly. Each volume button 934 or 944 is correspondingly disposed within the volume button hole of the earhook housing and exposed through the volume button hole, so that the user can control the corresponding audio processing chip by pressing or dialing the volume button, thereby adjusting the audio gain of the corresponding speaker assembly.

[0094] In some embodiments, the volume button 934 and the volume button 944 can be referred to as interactive components. In some embodiments, the interactive components (volume button 934 and volume button 944) and the main circuit board 932 can be collectively referred to as a control circuit component. In this case, two independent audio processing chips can be integrated on the main circuit board 932. In some embodiments, the control circuit component may further include a sub-circuit board 942. In some embodiments, the main circuit board 932 and the sub-circuit board 942 can be located in the corresponding accommodation spaces of different ear hook shells. For example, the main circuit board 932 can be coupled to the volume button 934 and cover the volume button hole corresponding to the volume button 934 to withstand the pressure applied by the user to the volume button 934. Similarly, the sub-circuit board 942 can be coupled to the volume button 944 and cover the volume button hole corresponding to the volume button 944 to withstand the pressure applied by the user to the volume button 944. In this application, the coupling between two elements can refer to a direct connection or an indirect connection. In some embodiments, the secondary circuit board 942 can also be electrically connected to the main circuit board 932 so that the main circuit board 932 can process the pressing operation of the volume button 944 coupled to the secondary circuit board 942. In some embodiments, the secondary circuit board and the battery assembly 946 can be disposed in the same accommodation space of the ear hook housing.

[0095] In some embodiments, the control circuit assembly may further include a function button 936. The function button 936 may be coupled to the main circuit board 932. In some embodiments, since the main circuit board 932 is generally smaller in volume than the battery assembly 946, the function button 936 may be disposed within the earhook housing on the side where the main circuit board 932 is located to balance the volume distribution of the acoustic device 900. In some embodiments, the function button 936 may replace the volume button 934 or coexist with the volume button 934. In some embodiments, the function button 936 may implement functions such as play / pause and power on / off to expand the interaction capabilities of the acoustic device 900 with the user.
