Technical Field

The present application relates generally to the field of electronic equipment, and more particularly, to an acoustic device.

Background

The bone conduction headset can convert sound into mechanical vibration of different frequencies, uses human bones/tissues as a medium for transmitting the mechanical vibration, and then transmits the mechanical vibration to auditory nerves, so that a user can receive the sound without passing through the external auditory canal and eardrum of the ear. For hearing impaired people (e.g., users with normal hearing in one ear and hearing impaired in one ear), they require higher acoustic performance (e.g., better sound pickup) and more sophisticated functional structure (e.g., volume control to match their hearing conditions) for bone conduction headphones due to their hearing impairment or degradation. Accordingly, it is desirable to provide an acoustic device having higher acoustic performance and a more sophisticated functional structure to meet the needs of users.

Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings used in the description of the embodiments will be briefly introduced below. It is obvious that the drawings in the following description are only examples or embodiments of the application, from which the application can also be applied to other similar scenarios without inventive effort for a person skilled in the art. Unless otherwise apparent from the context, or otherwise indicated, like reference numbers in the figures refer to the same structure or operation.

As used in this application and in the claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to include the plural, unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.

It should be understood that the terms "data block," "system," "engine," "unit," "component," "module," and/or "block" as used herein are a means for distinguishing between different components, elements, components, parts, or parts of a component at different levels. However, other words may be substituted by other expressions if they accomplish the same purpose.

Various terms are used to describe spatial and functional relationships between elements (e.g., between layers), including "connected," engaged, "" interface, "and" coupled. Unless explicitly described as "direct," when a relationship between a first and a second element is described in the present application, the relationship includes a direct relationship in which no other intermediate element exists between the first and the second element, and an indirect relationship in which one or more intermediate elements exist (spatially or functionally) between the first and the second element. In contrast, when an element is referred to as being "directly connected," joined, interfaced, or coupled to another element, there are no intervening elements present. In addition, the spatial and functional relationships between elements may be implemented in various ways. For example, the mechanical connection between two elements may include a welded connection, a keyed connection, a pinned connection, an interference fit connection, or the like, or any combination thereof. Other words used to describe relationships between elements should be interpreted in a similar manner (e.g., "between," "and.. between," "adjacent" and "directly adjacent," etc.).

An acoustic device is provided. The acoustic device may include a housing, one or more pickup assemblies, and one or more channel members. The housing may have an accommodating space and one or more communication holes. Each communication hole communicates the accommodation space with the outside. The one or more pickup assemblies may be disposed in the accommodating space for picking up sound through the communication hole. The one or more channel members may be disposed in the receiving space, wherein at least one of the one or more channel members is disposed between a sound pickup element of the one or more sound pickup assemblies and a communication hole of the one or more communication holes, so that the sound is transmitted to the sound pickup element through the communication hole and then through the at least one of the one or more channel members. Therefore, the sound path of the corresponding sound pickup assembly can be prolonged by arranging one or more channel pieces, so that the phenomenon of wind noise caused by the fact that the sound path of the sound pickup assembly is too short is improved. In addition, in some embodiments, by providing a plurality of sound pickup assemblies capable of independently picking up sound and processing (e.g., amplifying) signals, different directions of sound can be accommodated, so that a wearer (e.g., a hearing-impaired person) can adapt to different directions of sound, and hearing effects of the wearer are improved.

In some embodiments, the acoustic device may further include a plurality of speaker components, a control circuit component, and a plurality of interaction components. The control circuit assembly may include a plurality of control elements, each control element corresponding to at least one speaker assembly of the plurality of speaker assemblies. Each interactive component corresponds to each loudspeaker component in the loudspeaker components and the corresponding control element, and is used for responding to the received user operation instruction and triggering the control element corresponding to the interactive component to control the corresponding loudspeaker component to realize the function corresponding to the user operation instruction. Therefore, for hearing impaired people (for example, a user with normal hearing in one ear and hearing impaired in one ear), the two speaker assemblies can be respectively and adaptively adjusted according to actual use requirements so as to adapt to different hearing of the two ears, so that the situation that the heard sound is always large on one side and small on the other side is avoided, and the user experience is further improved.

FIG. 1 is a block diagram of an exemplary acoustic device according to some embodiments of the present application. The acoustic device 100 may pick up a user's voice, an environmental sound of an environment in which the user is located, and the like, and convert the picked-up sound into an audio signal (e.g., an electrical signal). In some embodiments, the acoustic device 100 may include a hearing aid, an earpiece (e.g., a noise reduction earpiece, a bone conduction earpiece), a listening bracelet, smart glasses, a cell phone, a microphone, or other device with sound pickup capabilities. As shown in fig. 1, the acoustic device 100 may include a support assembly 110, a engine block 120, and a tunnel member 130.

The support assembly 110 may have an accommodating space and a housing provided with a communication hole. The communicating hole can communicate the accommodating space with the outside. In some embodiments, one or more components of the acoustic device 100 may be disposed in the receiving space. For example, the movement module 120 and the channel member 130 may be located in the accommodating space. Also for example, cartridge module 120 may include a plurality of pickup assemblies. A plurality of pickup assemblies can be arranged in the accommodating space at intervals.

In some embodiments, the housing may include a first housing and a second housing. The first shell and the second shell can be connected in a matching mode to form the accommodating space. The second housing may include a bottom wall and a side wall that is joined to the bottom wall. The first shell can be physically connected to the side wall to form an accommodating space. In some embodiments, a flange may be protruded from a side of the bottom wall facing the first housing to form a receiving groove for receiving the pickup assembly. Channel member 130 may be configured to cover the flange to hold the pickup assembly in place within the receiving cavity. In this application, the certain surface that passageway piece can indicate the passageway piece with the holding tank pressure holding of passageway piece can form the holding chamber in the holding tank, can laminate with the lateral wall in holding chamber when this holding chamber is arranged in to the pickup subassembly.

In some embodiments, the shape of the support member 110 (e.g., the housing) may be configured accordingly according to the specific use requirements of the acoustic device 100, and is not particularly limited herein. For example, the acoustic device 100 may be a bone conduction hearing aid, and the support member 110 may be configured to interact with the pinna of the user such that the bone conduction hearing aid may be hung on the ear of the user and not be easily dropped. The bone conduction hearing aid provided with the support member 110 may also be referred to as an ear-hang hearing aid. As another example, the acoustic device 100 may be an open binaural earphone, and the support member 110 may be suspended across the top of the user's head, secured to the person's head in a headband-like manner, and spaced from the user's ears at opposite ends. As another example, support assembly 110 may be a structure as shown in FIG. 2, including 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 earhook assembly. The third portion 216 may also be referred to as a rear hang assembly. Further description of the earhook assembly and/or the rear hook assembly may be found elsewhere in this application (e.g., fig. 2, 3, and 4 and their associated descriptions).

In some embodiments, the support member 110 may be made of a metal material (e.g., copper, aluminum, titanium, gold, etc.), an alloy material (e.g., an aluminum alloy, a titanium alloy, etc.), a plastic material (e.g., polyethylene, polypropylene, epoxy, nylon, etc.), a fiber material (e.g., acetate, propionate, carbon fiber, etc.), and the like. In some embodiments, a sheath may be disposed externally to support assembly 110. The sheath can be made of soft materials with certain elasticity, such as soft silica gel, rubber and the like, and provides a better touch feeling for a user to wear.

The engine module 120 may include a pickup assembly. The sound pickup assembly may be used to pick up sound (i.e., mechanical vibration signals) through the communication holes of the housing surface and convert the picked-up sound into audio signals (e.g., electrical signals). In some embodiments, the acoustic apparatus 100 may transmit the audio signal to other acoustic devices, such as a speaker, a horn, and the like. In some embodiments, the acoustic device 100 may transmit the audio signal to other components in the acoustic device 100, for example, the movement module 120 may further include a speaker assembly, so that the audio signal is converted into a mechanical vibration signal through the speaker assembly, transmitted to the auditory nerve through the bones of the wearer, and the like, to achieve a hearing aid function. In some embodiments, the speaker assembly may be physically connected to other components of the acoustic device 100, such as the support assembly 110, the pickup assembly. By way of example only, the physical connection may include injection molded connections, welds, rivets, bolts, adhesives, snaps, and the like, or any combination thereof. In some embodiments, the pickup assembly may include one or more microphones (e.g., a microphone array). In some embodiments, the acoustic device 100 may include multiple pickup assemblies. One communication hole may correspond to each pickup assembly. A plurality of pickup assemblies may be spaced apart within the housing. Reference may be made elsewhere in this application to more locations for placement of the plurality of pickup assemblies (e.g., fig. 2 and 7 and their description).

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 communication hole, so that sound is transmitted to the pickup assembly through the channel member 130 after passing through the communication hole. In some embodiments, at least one pickup assembly of the one or more pickup assemblies may correspond to one of the channel members 130 to facilitate improved pickup of the corresponding pickup assembly. In some embodiments, the channel member 130 may include a first hole (which may also be referred to as a sound inlet hole), a channel, and a second hole (which may also be referred to as a sound outlet hole). In some embodiments, the first aperture and the communication aperture may be in abutting communication, and the second aperture may be disposed adjacent the pickup assembly such that sound is transmitted to the pickup assembly through the communication aperture, the first aperture, the channel, and the second aperture in sequence. Further description of the channel member may be found elsewhere in this application (e.g., fig. 6A-6B and their associated description).

In some embodiments, the acoustic device 100 may also include control circuit components and one or more interactive components (not shown in the figures). The control circuit components may be used to control the acoustic device 100, such as volume control, on/off control, operational mode selection (e.g., play/pause), wireless connection, or data transmission control, among others. In some embodiments, the control circuit assembly may include a plurality of control elements. Each control element may correspond to at least one speaker assembly of the plurality of speaker assemblies. Each interactive component may correspond to each speaker component and its corresponding control element. Each interactive component can be used for receiving a user operation instruction and triggering a control element corresponding to the interactive component to control a corresponding loudspeaker component to realize a function corresponding to the user operation instruction. Further description of the control circuit components and the interaction components may be found elsewhere in this application (e.g., fig. 8 and 9 and their associated description).

In some embodiments, the acoustic device 100 may also include a shield assembly (not shown). In some embodiments, the protective component may have a function of protecting the acoustic device 100, for example, a waterproof function, a dustproof function. In some embodiments, a protective component may be disposed within and physically connected to the support component 110 to form a protective barrier that protects the acoustic device 100. For example, the core module 120 may be disposed in an accommodating space inside a housing of the supporting component 110, and the protection component may be disposed between the core module 120 and the housing of the supporting component 110 to form a protection block for protecting the core module 120, so as to achieve functions of water proofing and dust proofing.

It should be noted that the above description of the acoustic device 100 is intended to be illustrative, and not to limit the scope of the present application. Many alternatives, modifications, and variations will be apparent to those skilled 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 also include a battery assembly, a bluetooth assembly, or the like, or combinations thereof. The battery assembly may be used to power the acoustic device 100. The bluetooth component may be used to wirelessly connect the acoustic apparatus 100 to other devices (e.g., cell phones, computers, etc.).

Fig. 2 is a schematic structural diagram of an exemplary acoustic device according to some embodiments of the present application. As shown in fig. 2, the 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.

The support assembly 210 may include a first portion 212 (i.e., an earhook assembly 212), a second portion 214 (i.e., an earhook assembly 214), and a third portion 216 (i.e., a rear hook assembly 216). Two ends of the rear suspension element 216 may be connected to one end of two ear suspension elements (i.e., the ear suspension element 212 and the ear suspension element 214), respectively. When the acoustic device 200 is worn by a user, the ear-hook assembly 212 and the ear-hook assembly 214 may be respectively hung on the ears of the user, and the rear-hook assembly 216 may be wound around the rear side of the head or neck of the user, so that the acoustic device 200 may be stably worn.

In some embodiments, the speaker assemblies 232 and 234 may 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) may be provided at the other ends of the two ear hook assemblies. For example, the ear hook assembly 212 and the ear hook assembly 214 may respectively include a receiving space, the speaker assembly 232 may be disposed in the receiving space of the ear hook assembly 212, and the speaker assembly 234 may be disposed in the receiving space of the ear hook assembly 214. When the acoustic apparatus 200 is worn, the two speaker assemblies may transmit mechanical vibrations through the bone and/or cochlea of the wearer to the human auditory system, thereby causing the wearer to hear sounds. In some embodiments, the speaker assemblies 232 and/or 234 may be self-contained with respect to the ear-hook assembly. That is, the speaker assemblies 232 and/or 234 may include speaker housings. The speaker housing may be coupled to the earhook assembly 212 and/or 214, and the speaker assembly may be disposed external to the earhook assembly 212 and the earhook assembly 214. Further description of the earhook assembly can be found in relation to the detailed description of fig. 3-4.

In some embodiments, one or more components of the acoustic device 200 may be disposed within the housing space formed by the support member 210. For example, as shown in fig. 2, the battery assembly 240 may be disposed in the accommodating space of the ear-hook assembly 212. The control circuit assembly 250 can be disposed in the receiving space of the ear-hook assembly 214. Also for example, the battery assembly 240 and/or the control circuit assembly 250 may be disposed in the rear suspension assembly 216. As another example, the acoustic device 200 may also include a bluetooth component. The bluetooth module may be disposed in the accommodating space of the rear suspension module 216. As another example, the acoustic device 200 may also include one or more channel members. At least one of the one or more channel members may be disposed between at least one of the one or more pickup assemblies and one of the one or more communication holes on the support assembly 210. Further description of the channel member may be found elsewhere in this application (e.g., as detailed in fig. 6A-6B).

In some embodiments, the acoustic device 200 may include multiple pickup assemblies, e.g., 2, 3, 4, 5, etc. Each of the pickup assemblies may be disposed near the communication holes on the support assembly 210 so that the pickup assembly may pick up sound through the corresponding communication hole. The plurality of pickup assemblies can be independent from each other, and can independently pick up sound and amplify signals from each other, and then can independently pick up and handle the sound in different positions, so that a wearer (for example, a hearing-impaired person) can adapt to the sound in different positions, and the hearing effect of the wearer is improved. In some embodiments, multiple pickup assemblies may be spaced at different locations on the support assembly 210. For example, multiple pickup assemblies may be spaced apart within trailing assembly 216 (e.g., location F, G, H, I). For another example, one of the pickup assemblies may be disposed at a middle position (i.e., position I) of the rear suspension assembly 216, and the remaining pickup assemblies may be disposed at intervals at one side or both sides of the middle position. As another example, multiple pickup assemblies may be spaced apart within the ear-hook assemblies 212 and/or 214. As another example, a portion of the plurality of pickup assemblies may be spaced apart within the earhook assembly (e.g., positions E and B in fig. 2 and/or positions O and D in fig. 4), and the remaining portion may be spaced apart within the rear hook assembly 216. In some embodiments, when a speaker assembly is present independently, multiple pickup assemblies may also be disposed within the speaker housing. In some embodiments, some of the plurality of pickup assemblies may be spaced apart within the support assembly 210 and the remaining portions may be spaced apart within the speaker housing. In some embodiments, the location of the pickup assembly may also be referred to as the location of its corresponding communication aperture.

It should be noted that, since the sound pickup assembly is mainly used for picking up the voice of the user, the environmental sound of the environment where the user is located, and the like, for the wearer (for example, the hearing impaired), the sound pickup effect of the sound pickup assembly will affect the clarity, stability, and the like of the sound received by the wearer through the acoustic device 200. In general, the pickup assembly may be disposed anywhere on the acoustic device 200. However, the closer the sound pickup unit is to the speaker unit, the more susceptible it is to the speaker unit, and the more susceptible it is to "howling" due to acoustic coupling between the two. Accordingly, the location of the sound pickup assembly may be determined based on the requirements for the howling threshold of the acoustic device 200. Reference may be made elsewhere in this application to more information about the relation between the howling threshold of the pickup assembly and its relative position on the acoustic device (e.g., fig. 7 and its description).

Fig. 3 is a schematic structural diagram of an exemplary earhook assembly according to some embodiments of the present application. Fig. 4 is a schematic view of the disassembled ear-hook assembly of fig. 3. As shown in fig. 3 and 4, the earhook assembly 300 can include an earhook housing 310, a coupling member 320, and a speaker housing 330. One end of the coupling member 320 may be coupled to the ear-hook housing 310 and the other end of the coupling member 320 may be coupled to the speaker housing 330.

In some embodiments, the ear hook housing 310, the connecting member 320, and/or the speaker housing 330 can be integrally formed. For example, the coupling member 320 may be coupled to the earhook housing 310 and the speaker housing 330 in an injection molded manner. In some embodiments, the earhook housing 310, the coupling member 320, and/or the speaker housing 330 can be coupled by a coupling structure to form a foldable earhook assembly. Exemplary connection structures may include snap-fit structures, bayonet structures, hinge structures, and the like, or combinations thereof.

In some embodiments, as shown in fig. 4, the earhook housing 310 may include a first earhook housing 312 and a second earhook housing 314. The first earhook housing 312 and the second earhook housing 314 can be coupled to form an accommodating space 360. The accommodation space 360 may accommodate one or more of a battery assembly, a control circuit assembly, a pickup assembly, a tunnel member, a bluetooth assembly, and the like. For example only, the receiving space 360 may receive the pickup assembly 340. In some embodiments, the second earhook housing 314 can be physically connected to the coupling member 320. For example, the second earhook housing 314 can be fixedly coupled to one end of the coupling member 320 by injection molding. For another example, the second earhook housing 314 may be connected to one end of the connecting member 320 by welding, riveting, bonding, clipping, or the like. 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 can be connected to the second earhook housing 314 by welding, riveting, bonding, snapping, etc. In some embodiments, the first earhook housing 312 and the second earhook housing 314 can be physically connected to the connection member 320. For example, the first earhook housing 312 and the second earhook housing 314 can be connected to one end of the connecting member 320 by injection molding.

In some embodiments, a receiving groove (e.g., receiving groove 525 in fig. 5) for receiving the pickup assembly 340 may be disposed in the receiving space 360. In some embodiments, the ear hook housing 310 is provided with a communication hole 350 for communicating the accommodating space 360 with the outside. The pickup assembly 340 may be disposed in the receiving space 360 and adjacent to the communication hole 350, so that the pickup assembly 340 can pick up the sound through the communication hole 350. In some embodiments, the distance between the pickup assembly 340 and the communication hole 350 may be not less than 1 mm. For example, the distance between the sound pickup assembly 340 and the communication hole 350 may be 1mm, 2mm, 3mm, 5mm, 7mm, 10mm, or the like. In some embodiments, the communication aperture 350 can be disposed on the first earhook housing 312 of the earhook housing 310. Further description of the first earhook housing 312 may be found elsewhere in this application (e.g., fig. 5 and its description).

Usually, the speaker assembly may drive the outside air to vibrate along with the sound, i.e. the "sound leakage" phenomenon occurs. Therefore, the communication hole 350 can be opened on a side of the ear-hook housing 310 away from the speaker assembly (located in the speaker housing 330) (e.g. position C) or away from the connecting part 320 (e.g. position D) to avoid "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 disposed at a side of the accommodating space 360 away from the speaker assembly, so that mechanical vibration generated by the speaker assembly can be reduced and transmitted to the sound pickup assembly 340, and thus occurrence of "howling" or noise generated by the sound pickup assembly 340 can be reduced. It should be noted that in some embodiments, the location of the communication hole 350 may also be referred to as the location of its corresponding pickup assembly. In some embodiments, the communication aperture 350 can also be open at other locations on the earhook housing 310. For example, the communication hole 350 may be opened on a side of the ear-hook housing 310 facing the speaker assembly, on a side of the acoustic device (or the ear-hook assembly 300) facing the head of the user when the acoustic device is worn, or on a side of the acoustic device (or the ear-hook assembly 300) facing away from the head of the user when the acoustic device is worn (e.g., position O). For example, the communication hole 350 may be provided at the position B, D, E on the first earhook housing 312.

In some embodiments, as shown in fig. 4, the connection member 320 may include a first elastic coating 321, a second elastic coating 322, and an elastic support 323. One end of the elastic support 323 may be connected to the earhook housing 310 (e.g., the second earhook housing 314), and the other end of the elastic support 323 may be connected to the speaker housing 330 (or speaker assembly). In some embodiments, a wire (not shown) may be disposed within coupling member 320. One end of the wire may be electrically connected to the sound pickup assembly 340, the battery assembly, the control circuit assembly, etc. disposed in the receiving space 360, and the other end of the wire may be electrically connected to the speaker assembly in the speaker housing 330.

In some embodiments, the first elastic coating 321 and the second elastic coating 322 may be formed by injection molding (e.g., two-shot molding) and wrap the elastic support 323 and the wires. In some embodiments, the resilient support 323 can wrap around the wire. In some embodiments, the resilient support 323 can be curved and have a degree of stiffness/strength to form the basic form of the ear hook assembly 300 to facilitate the user's wearing of the acoustic device. The first elastic coating 321 and the second elastic coating 322 may protect the elastic support 323 and the wire wrapped thereby. In some embodiments, the first elastic coating 321 and the second elastic coating 322 may be made of a soft material with certain elasticity, such as soft silicone, rubber, fiber, etc., to provide a better tactile sensation for the user to wear. In some embodiments, the split seam of the first elastic covering 321 and the second elastic covering 322 may divide the surface of the connecting member 320 into inner and outer sides that are disposed opposite to each other. Here, an exposed surface of the first elastic coating 321 may serve as an inner side of the connection member 320, and an exposed surface of the second elastic coating 322 may serve as an outer side of the connection member 320. It should be noted that, when the acoustic device (or the ear hook assembly 300) is in the wearing state, the inner side surface of the connecting member 320 is closer to the skin of the wearer than the outer side surface. The inside surface of the link member 320 is mostly in contact with the user's ear and the head in the vicinity thereof.

In some embodiments, the connecting member 320 may be made with an auxiliary wire. The auxiliary wire may be arranged side by side with the elastic support 323. In some embodiments, the auxiliary wires and the elastic support 323 may have substantially the same shape, length, radius of curvature, and other structural parameters. In some embodiments, the diameter of the auxiliary wire may be less than or equal to the diameter of the wire. Further, an elastic coating may be formed on the surfaces of the auxiliary wire and the elastic supporting member 323 by injection molding, and the auxiliary wire may be drawn out to obtain the connection member 320. Finally, in the fabrication of the acoustic device, the wires may be threaded into the elastic covering (i.e., where the auxiliary wires were originally located). However, in the injection molding process, since the auxiliary wire and the elastic support 323 have a certain length and a certain radius of curvature, the auxiliary wire and the elastic support may deviate from the original position (especially, the middle area thereof) under the impact of the injection molding material, and finally the wall thickness of the elastic coating is not uniform, which affects the molding quality of the connection member 320. Particularly when the elastic coating is designed to have a thin wall thickness, the connection member 320 may have a "skin-broken" undesirable phenomenon during a long-term use of the acoustic device, thereby affecting the user experience.

In some embodiments, the elastic coating may 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 may be injection molded in two parts. Specifically, a through groove 324 may be formed at one side of one of the elastic coating layers (e.g., the first elastic coating layer 321). The through groove 324 may be extended in an extending direction of the first elastic coating 321, and may be used to place the elastic support 323 and the auxiliary wire. Further, the second elastic coating 322 may be formed on the side where the through groove 324 of the first elastic coating 321 is located by injection molding, and covers the elastic supporting member 323 and the auxiliary wire, so that after the first elastic coating 321 and the second elastic coating 322 are spliced and fixed, a wire guiding channel (not labeled in fig. 4) that is arranged in parallel with the elastic supporting member 323 and is communicated with the accommodating space 360 is formed by drawing out the auxiliary wire. The lead channels may be used to pass wires. It should be noted that, since the through grooves 324 have a certain depth, the first elastic coating 321 may partially wrap the elastic supporting member 323 and the auxiliary wires to limit the elastic supporting member 323 and the auxiliary wires, so that the elastic supporting member 323 and the auxiliary wires can resist the impact of the injection molding material, which is beneficial to improving the problem that the elastic supporting member 323 and the auxiliary wires deviate from the original positions.

In some embodiments, the depth of the through slots 324 may be equal to the radius of the larger diameter of the resilient support 323 and the secondary wire. In some embodiments, the depth of the through groove 324 may be greater than the radius of the smaller diameter of the elastic support 323 and the auxiliary wire, and less than the radius of the larger diameter of the elastic support 323 and the auxiliary wire. In some embodiments, the depth of the through slots 324 may be greater than the radius of the larger diameter of the resilient support 323 and the secondary wire. In some embodiments, the number of through slots 324 may be two. The two through slots 324 may be disposed side by side and used to place the elastic support 323 and the auxiliary wire, respectively, such that the wire guiding passage and the elastic support 323 are spaced apart from each other, which may allow the elastic support 323 and the auxiliary wire (or the conductive wire) to be free from interference. In some embodiments, the number of the through slots 324 may be one, and the elastic supporting member 323 and the auxiliary wire may be jointly received in the through slots 324, so that the elastic supporting member 323 can be exposed to the lead passage, which may simplify the structure of the connection member 320.

In some embodiments, the earhook housing 310 (e.g., the second earhook housing 314) may be coupled to one end of the coupling member 320 (e.g., the resilient support 323) in an injection molded manner. Further, the second elastic coating 322 can be coupled to the third elastic coating 316 covering at least a portion of the outer surface of the earhook housing 310 by injection molding. The first resilient coating 321 may be between the earhook housing 310 and the speaker housing 330 and does not coat the outer surface of the earhook housing 310. For example, the second elastic coating 322 may coat the outer surface of the first earhook housing 312, i.e. the third elastic coating 316 is the same coating as the second elastic coating 322, and the first elastic coating 321 may be between the first earhook housing 312 and the speaker housing 330 and not coat the outer surface of the first earhook housing 312.

In some embodiments, the molding process of the earhook assembly 300 may include the following operations: operation 1) forming a speaker housing 330 and a second earhook housing 314 at both ends of the elastic support 323, respectively; operation 2) obtaining a first elastic coating 321 with through slots 324 by means of a first injection molding; operation 3) assembling the first elastic coating 321 obtained in operation 2) with the semi-finished product and the auxiliary wire in operation 1); operation 4) forming a second elastic coating 322 on the side where the through groove 324 of the first elastic coating 321 is located, and forming a third elastic coating 316 on the side of the outer surface of the second earhook housing 314 by a second injection molding to wrap the elastic support 323 and the auxiliary wire and wrap the outer surface of the second earhook housing 314; operation 5) drawing out the auxiliary metal wire of the semi-finished product obtained in operation 4) to form a lead channel, and then penetrating a lead in the lead channel; operation 6) the first earhook housing 312 is fixed to the second earhook housing 314 in operation 5) by one or a combination of gluing, clamping, screwing and the like.

It should be noted that the acoustic device may include two ear hook assemblies 300, the number of the sound pickup assemblies 340 may correspond to two, and the number of the channel members may correspond to two. Specifically, a sound pickup assembly 340 and a channel member may be respectively disposed in the accommodating space 360 of each ear hook assembly 300, so as to improve the sound pickup effect of each sound pickup assembly 340.

Fig. 5 is a schematic view of the first earhook housing of fig. 4. As shown in fig. 5, the first earhook housing 312 can include a bottom wall 3122 and a side wall 3124 that is circumjacent to the bottom wall 3122. The second ear-hook housing 314 can cover the side wall 3124 and is disposed opposite to the bottom wall 3122 to form an accommodating space 360. In some embodiments, a receiving groove 525 for receiving the pickup assembly 340 may be disposed in the receiving space 360. In some embodiments, a flange 3126 can be convexly provided at a side of the bottom wall 3122 facing the second earhook housing 314. The flange 3126 may enclose a receiving groove 525 to provide a positive retention of the pickup assembly 340. In some embodiments, the flange 3126 and at least a portion of the side wall 3124 may collectively enclose the receiving slot 525.

In some embodiments, the first earhook housing 312 can have a communication aperture 350 formed therein. In some embodiments, to minimize interference with the pickup assembly from the speaker assembly, the communication hole 350 may be formed in the side wall 3124 at a location remote from the speaker assembly (e.g., location C in fig. 4). In some embodiments, the communication hole 350 may also open on the bottom wall 3122.

It should be noted that if the sound pickup assembly 340 directly communicates with the outside through the communication hole 350, the sound path between the sound pickup assembly 340 and the outside (also referred to simply as the sound path of the sound pickup assembly 340) will be short. When the acoustic device is in a complex environment (e.g., air flow is severe), the pickup assembly 340 picks up more noise, causing a "wind noise" phenomenon. The "wind noise" phenomenon may refer to a phenomenon in which the sound pickup assembly 340 picks up external noise to generate noise. Therefore, according to some embodiments of the present disclosure, a channel member (e.g., channel member 600 shown in fig. 6A) may be disposed between the pickup assembly 340 and the communication hole 350 to extend the sound path of the pickup assembly 340, thereby improving the pickup effect of the pickup assembly 340. In some embodiments, the channel member may include a first hole (also referred to as a sound inlet), a channel, and a second hole (also referred to as a sound outlet). In some embodiments, the channel member may be disposed in the receiving space 360 and the cover is disposed on the flange 3126. In other words, the channel can cover the receiving cavity 525 and press the sound pickup assembly 340 into the receiving cavity 525, and the sound inlet hole faces the side wall 3124 and is in butt communication with the communication hole 350, and the sound outlet hole is in butt communication with the sound pickup assembly 340. So set up, the sound way of pickup subassembly has both been prolonged to the passageway piece, has realized the fixed to the pickup subassembly again. More description of the channel member may be found elsewhere in this application (e.g., fig. 6A and its description).

In some embodiments, the communication hole 350 may be a slit with a certain width (e.g., 0.2mm, 0.5mm, 1mm, etc.) to increase the contact area of the sound path of the sound pickup assembly 340 with the outside, thereby improving the sound pickup effect of the sound pickup assembly 340. In some embodiments, the shape of the communication aperture 350 may be circular, square, oval, triangular, etc. In some embodiments, in order to prevent the sound path of the sound pickup assembly 340 from contacting the outside with too large an area to cause the reduction of the waterproof and dustproof performance of the ear-hung shell 310 and/or to cause the phenomenon of "wind noise", a guard 540 may be disposed on the sound path of the sound pickup assembly 340. By way of example only, a shield 540 may be disposed between the channel member and the earhook housing 310, thereby spacing the communication aperture 350 from the sound inlet aperture of the channel member for enhancing the wind and noise reduction capabilities of the pickup assembly 340 and improving the waterproof and dustproof capabilities of the earhook assembly 300. In some embodiments, the shield 540 may include one or more nets, such as a first net 542 and a second net 544, arranged in a stack. In some embodiments, one or more webs may be made of different or the same materials. In some embodiments, the first mesh 542 may comprise a metallic mesh (e.g., iron mesh, aluminum mesh) and the second mesh 544 may comprise a non-metallic mesh (e.g., nylon mesh, cotton hemp mesh). In some embodiments, the second web 544 is closer to the channel member than the first web 542. In some embodiments, the structural strength of the first mesh 542 may be greater than the structural strength of the second mesh 544. In some embodiments, the mesh size of the second net 544 may be larger than the mesh size of the first net 542, and the two mesh sizes cooperate to enable the guard 540 to take into account the structural strength of the guard, the sound pickup requirements of the sound pickup assembly 340, and the waterproof and dustproof requirements of the ear hook assembly 300.

In some embodiments, the first earhook housing 312 may further include a volume key hole 550 and/or a function key hole 555. The volume buttons may be disposed in the volume button holes 550 and exposed through the volume button holes 550, so that a user can control a corresponding processing chip on a circuit board of the acoustic device by pressing/dialing the volume buttons, thereby adjusting an audio gain of a speaker assembly of the acoustic device. Similarly, the function keys may be disposed in the function key hole 555 and exposed through the function key hole 555, so that the user may control the corresponding processing chip on the circuit board in the acoustic device by pressing/shifting the function keys, and then adjust the corresponding functions of the acoustic device. In some embodiments, the function controlled by the function key may include controlling on/off, controlling pause/play, controlling wireless connection or data transmission, and the like, or any combination thereof.

FIG. 6A is a schematic diagram of a channel member according to some embodiments of the present application. Fig. 6B is a schematic structural diagram of the pickup assembly of fig. 3. As shown in fig. 6A, the passage member 600 may include a first hole 610 (may also be referred to as a sound input hole), a passage 620, and a second hole 630 (may also be referred to as a sound output hole). The sound inlet 610 and the sound outlet 630 may be spaced apart and communicate with the passage 620, respectively. The sound inlet 610 can be in abutting communication with a communication aperture on the ear-hook assembly (e.g., the communication aperture 350 on the ear-hook assembly 300). A sound outlet hole 630 may be provided adjacent to the sound pickup assembly 340 so that sound can be transmitted to the sound pickup assembly 340 through the communication hole, the sound inlet hole 610, the passage 620, and the sound outlet hole 630 in this order.

In some embodiments, the shape of the sound inlet hole 610 may be the same as or similar to the shape of the communication hole. For example, when the communication hole is a slit having a certain width, the sound inlet hole 610 may be provided in the form of a slit. For example, when the communication hole is formed in a circular hole shape, the sound inlet hole 610 may be formed in an elliptical hole shape or a circular hole shape.

In some embodiments, the channel 620 may include a channel top wall 640, a channel bottom wall 650, and a channel side wall 660. The channel top wall 640 and the channel bottom wall 650 may be located at both ends of the channel side wall 660, respectively. Specifically, the channel top wall 640 and the channel bottom wall 650 may be oppositely disposed, and the channel side wall 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 in a direction along the connecting channel top wall 640 and channel bottom wall 650 may range from 0.45 to 0.75 mm. For example, the length of the channel 620 in a direction along the connecting channel top wall 640 and channel bottom wall 650 may be 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm, etc. In some embodiments, when channel member 600 presses against pickup assembly 340, in particular, pickup assembly 340 may be pressed against channel bottom wall 650. Illustratively, the channel top wall 640 and the channel bottom wall 650 are spaced apart in parallel such that the channel 620 is disposed in a flat configuration to accommodate the flat configuration of the housing.

In some embodiments, the sound inlet 610 may open at the channel sidewall 660 or the channel top wall 640, and the sound outlet 630 may open at the channel bottom wall 650. In some embodiments, sound inlet hole 610 may be spaced from sound outlet hole 630 along channel 620 by a distance greater than or equal to 4mm in order to extend the acoustic path of sound pickup assembly 340. For example, the sound inlet 610 may be spaced from the sound outlet 630 along the channel 620 by 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 8mm, 10mm, etc. In some embodiments, the channel member 600 may be a tubular structure open at both ends, consisting of only side walls. The tubular structure may have one end opened to form the sound inlet hole and the other end opened to form the sound outlet hole.

In some embodiments, as shown in fig. 6B, pickup assembly 340 may include a pickup element 342 and a protective sleeve 344. The protective sleeve 344 may be disposed around the pickup element 342. In some embodiments, the protective sleeve 344 may define a recess 346 facing the bottom wall 650 of the passage, and the pickup element 342 may be at least partially disposed in the recess 346. So configured, when the channel member 600 (e.g. the channel bottom wall 650 of the channel member 600) presses the sound pickup assembly 340 into the receiving cavity 525 (i.e. the channel member 600 covers the sound pickup assembly 340), the protective sleeve 344 may abut against and abut against the side wall (e.g. the flange 3126) of the receiving cavity 525, and the groove 346 and the sound outlet hole 630 may be in butt communication, so that the picked-up sound may enter the sound pickup element 342 through the sound outlet hole 630 and the groove 346. It should be noted that, in the present application, the abutting of the protective sleeve 344 with the side wall of the receiving groove 525 means that there is an acting force between the protective sleeve 344 and the side wall of the receiving groove, so that the protective sleeve 344 and the side wall of the receiving groove can be tightly attached. In some embodiments, the protective sleeve 344 may have elasticity (e.g., a silicone sleeve), so that during an assembling process of the acoustic device, the protective sleeve 344 can be elastically deformed to increase a fixing effect of the receiving groove sidewall on the pickup assembly 340 and to increase a sealing property of an acoustic path between the pickup assembly 340 and the channel member 600, thereby improving a pickup effect of the pickup assembly 340. In some embodiments, the protective sleeve 344 and the sound pickup element 342 may be closely attached to each other, and a sound pickup portion (e.g., a diaphragm) of the sound pickup element 342 may be exposed to the groove 346, so that sound is not easily leaked to the rear side of the sound pickup element 342 from between the protective sleeve 344 and the sound pickup element 342 after being transmitted to the groove 346, and thus, a sound pickup effect of the sound pickup element 342 can be better maintained.

Fig. 7 is a graph of howling threshold versus location of a sound pickup assembly in an acoustic device according to some embodiments of the present application. As shown in fig. 7, the abscissa may represent the position of the sound pickup assembly (or the communication hole corresponding to the sound pickup assembly) in the acoustic device, and the ordinate may represent the howling threshold (in dB) of the sound pickup assembly. It should be noted that the larger the howling threshold of the sound pickup assembly is, the lower the probability of the sound pickup assembly generating the "howling" phenomenon is, and the smaller the sound pickup assembly is affected by the speaker assembly.

In fig. 7, positions O, B, C, D, E, F, G, H and I indicate that the pickup assembly is disposed at positions O, B, C, D, E, F, G, H and I in fig. 2 and 4, respectively. The earhook assembly 300 of fig. 4 may be an exemplary structure of the earhook assembly 212 and/or 214 of the acoustic device of fig. 2. As shown in fig. 2 and 4, when the acoustic device is in a wearing state, the position O is located on an outer side of the ear-hook assembly 300 facing away from the user's head, the position B, E is located above the ear-hook housing 310 of the ear-hook assembly 300, and the position E is located further away from the speaker assembly than the position B, the position D is located below the ear-hook housing 310, and the position C is located behind the ear-hook housing 310 facing away from the speaker assembly. Further, for the rear suspension assembly, in conjunction with fig. 2, location F, G, H, I is sequentially directed away from speaker assemblies 232 and/or 234. Wherein position I may correspond to a middle position of the trailing assembly 216.

The howling threshold corresponding to the location O may be used as a reference threshold, that is, the howling threshold defining the location O is 0. According to fig. 7, the howling threshold at position B, C, D, E, F, G, H, I is greater than 0, which means that the sound pickup assembly is located at these positions to improve the "howling" phenomenon. Further, the howling threshold at position F, G, H, I is significantly higher than the howling threshold at position B, C, D, E, which indicates that the sound-pickup assembly is more advantageous to improve the "howling" phenomenon. It is noted that the howling threshold at position C, E is also significantly higher than the howling threshold at position B, D for the earhook housing, indicating that the more the sound pick-up assembly is disposed on the earhook housing away from the speaker assembly, the more beneficial the "howling" phenomenon is. For position E, the ear-hook assembly may interfere structurally with the rear-hook assembly, so placement of the pickup assembly at position C on the ear-hook assembly is a priority.

FIG. 8 is a block diagram of the structure of an exemplary acoustic device according to some embodiments of the present application. As shown in fig. 8, the acoustic device 800 may include a plurality of speaker assemblies 810 (e.g., speaker assemblies 810-1, 810-2), a control circuit assembly 820, and a plurality of interaction assemblies 830 (e.g., interaction assemblies 830-1, 830-2).

The speaker assembly 810 may be used to convert audio signals (e.g., electrical signals) into mechanical vibration signals. For example, the speaker assembly 810 may receive audio signals from a microphone, cell phone, MP3 player, etc., and convert them into mechanical vibration signals, thereby generating sound. In some embodiments, the speaker assembly 810 may include a bone conduction speaker, an air conduction speaker, or the like, or combinations thereof. For example only, the speaker assembly 810 may be a bone conduction speaker. The bone conduction speaker may include a magnetic circuit assembly, a vibration assembly, and a speaker housing. The magnetic circuit assembly may be used to provide a magnetic field. When the vibration assembly receives the audio signal, the audio signal can be converted into a mechanical vibration signal under the action of the magnetic field. For example, the vibration assembly may include a voice coil and a vibration plate, the voice coil is disposed in a magnetic gap formed by the magnetic circuit assembly, and the voice coil vibrates under the action of a magnetic field after the speaker assembly 810 receives an electrical signal (i.e., an audio signal). The voice coil is physically connected to the vibration plate and transmits vibration to the vibration plate. The speaker housing may include a vibration panel (i.e., a vibration plate) that faces the user's body. The speaker housing may house a vibration assembly. In some embodiments, the vibration assembly may be physically coupled to the vibration panel to vibrate the vibration panel for transmission through the user's head to his auditory nerve, thereby enabling the user to hear the sound.

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

The control circuit component 820 may be used to control other components of the acoustic device 800 (e.g., the speaker component 810) to implement one or more functions of the acoustic device 800. In some embodiments, control circuitry component 820 may include a plurality of control elements (e.g., control elements 820-1, 820-2, etc.). Each control element may control at least one speaker assembly, respectively, to independently control the speaker assembly, e.g., independently control the audio gain of the corresponding speaker assembly. In some embodiments, the control circuit component 820 may also include one or more function keys to control the turning on/off, pausing/playing, wirelessly connecting/disconnecting, etc. of the acoustic device 800. More description of the control circuit components may be found elsewhere in this application (e.g., fig. 9 and its description).

The interaction component 830 may be used to enable interaction between a user and the acoustic device 800. For example, the interaction component 830 may be used to enable interaction between a user and the speaker component 810, the control circuit component 820. Further, the interaction component 830 may trigger the control circuit component 820 to control the acoustic device 800 to implement a function corresponding to the user operation instruction in response to receiving the user operation instruction. For example, the interaction component 830 may control the control circuit component 820 to implement the power on and power off of the acoustic device 800 in response to receiving a pressing instruction of a user. For another example, each interactive component may correspond to a speaker component and its corresponding control element. Further, each interactive component may be configured to trigger a control element in the control circuit component 820 to control the corresponding speaker component 810 to implement a function corresponding to a user operation instruction in response to receiving the user operation instruction. For example, the interaction component 830-1 may control the control element 820-1 to effect an increase or decrease in the audio gain of the speaker component 810-1 in response to receiving a press or dial instruction by a user.

In some embodiments, the interaction component 830 may include one or more third apertures disposed on a support component (e.g., an ear-hook component) of the acoustic device 800 and first components respectively disposed in the third apertures for triggering the control circuit component 820 (e.g., a control element) to control one or more functions of the acoustic device 800. The first component may be configured to receive a user operation instruction. In some embodiments, the user instructions may be embodied in the form of force, sound, or the like. For example, the user may generate the user operation instruction by pressing, dialing, or the like. For another example, the first component may be a sound sensor that may receive a user sound to generate the user operation instruction. In some embodiments, the first component may include one or more keys, for example, a volume key and a function key. In some embodiments, control circuitry component 820 (e.g., each control element) may include a second component. The second component may trigger the control circuit assembly 820 to implement a function corresponding to an operation instruction, such as volume increase or decrease, play/pause, power on/off, and the like, in response to a user operation instruction (e.g., pressing, touching) received by the first component. In some embodiments, the second component may include a function switch, such as a mechanical switch, voice-activated switch, or the like. For example, one side of the first component may be provided with a switch accommodating area.

For another example, the second component may trigger the function switch in response to an intensity of sound to implement a function corresponding to the second component.

Fig. 9 is a schematic diagram of an exemplary acoustic device according to some embodiments of the present application. As shown in fig. 9, the acoustic device 900 may include a speaker component 910, a speaker component 920, an earhook component 930, an earhook component 940, and a rear hook component 950. It should be noted that, a part of the housing and each component accommodated in the corresponding accommodating space thereof may be collectively referred to as a housing component. Specifically, two ends of the rear-hanging component 950 can be respectively provided with one ear-hanging component 930 and 940 and one corresponding speaker component 910 and 920. In some embodiments, electrical devices (e.g., a sound pickup assembly, a speaker assembly, etc.) at two ends of the rear hanging assembly 950 can be electrically connected through wires embedded in the rear hanging assembly 950, so as to transmit control commands, electric energy, etc.

In some embodiments, the ear-hook assembly 930 may include a main circuit board 932, volume keys 934, function keys 936, pickup assembly 938, and the like, or any combination thereof. The ear-hook assembly 940 may include a secondary circuit board 942, volume button 944, battery assembly 946, pickup assembly 948, and the like, or any combination thereof. In some embodiments, the main circuit board 932 may be received in the receiving space of the ear hook assembly 930, and the battery assembly 946 may be received in the receiving space of the ear hook assembly 940, so as to balance the weight distribution of the acoustic device 900.

In some embodiments, two independent audio processing chips (also referred to as control elements) may be integrated on the main circuit board 932 to independently control the audio gain of the two speaker assemblies 910 and 920, respectively. In some embodiments, an audio processing chip for controlling the speaker assembly 910 may be integrated on the main circuit board 932 to separately control the audio gain of the speaker assembly 910, and an audio processing chip for controlling the speaker assembly 920 may be integrated on the sub circuit board 942 to separately control the audio gain of the speaker assembly 920. For example only, the audio processing chip may be a Digital Signal Processing (DSP) chip.

In some embodiments, a user may control the two speaker assemblies 910 and 920, respectively, through the two volume keys 934 and 944. For example, a volume key hole communicated with the accommodating space may be formed on the ear hook housing corresponding to each ear hook assembly. Each volume button 934 or 944 is correspondingly disposed in a volume button hole of the ear-hook housing and exposed through the volume button hole, so that a user can control the corresponding audio processing chip by pressing or dialing the volume button, and then adjust the audio gain of the corresponding speaker assembly.

In some embodiments, volume keys 934, 944 may be referred to as interactive components. In some embodiments, the interaction components (volume button 934 and volume button 944) and the main circuit board 932 may be collectively referred to as control circuit components. In this case, two audio processing chips independent of each other may be integrated on the main circuit board 932. In some embodiments, the control circuit assembly may also include a secondary circuit board 942. In some embodiments, the main circuit board 932 and the sub circuit board 942 can be located in the corresponding accommodating spaces of different ear hook housings. For example, the main circuit board 932 may be coupled with the volume keys 934 and cover volume key holes corresponding to the volume keys 934 so as to withstand pressing forces applied by a user to the volume keys 934. Similarly, the sub circuit board 942 may be coupled with the volume keys 944 and cover volume key holes corresponding to the volume keys 944 so as to receive a pressing force applied to the volume keys 944 by a user. In this application, coupling between two elements may refer to either a direct connection or an indirect connection. In some embodiments, the sub circuit board 942 may also be electrically connected to the main circuit board 932 to facilitate the main circuit board 932 in handling the pressing operation of the volume button 944 coupled to the sub circuit board 942. In some embodiments, the secondary circuit board and the battery assembly 946 may be disposed within the same ear-hook housing receptacle.

In some embodiments, the control circuit assembly may also include function keys 936. The function keys 936 may be coupled with the main circuit board 932. In some embodiments, because the main circuit board 932 is generally smaller in volume than the battery assembly 946, the function keys 936 may be disposed in the earhook housing on the side of the main circuit board 932 to equalize the volume distribution of the acoustic device 900. In some embodiments, function keys 936 may be substituted for the volume keys 934 or may be co-located with the volume keys 934. In some embodiments, the function keys 936 may implement play/pause, power on/off, and the like to extend the interaction capability of the acoustic apparatus 900 with the user.
