DETAILED DESCRIPTION

[0069] The application will be described in further detail below with specific reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that the application can be practiced without these specific details. In other instances, well-known methods have not been described in detail in order not to unnecessarily obscure the application. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that the application can be practiced without these specific details. In some instances, well-known operations and methods have not been described in detail in order not to unnecessarily obscure the application.

[0070] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that can be obviously seen by those skilled in the art. Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0071] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0072] The application provides a wearable device, for example, Figure 1 shows the overall outline structure of an in-ear hearing aid, which can be a specific embodiment of the actual application of the wearable device; The wearable device includes a shell assembly 100, a core assembly, a speaker device, and other functional components as needed, which will be described in detail below.

[0073] The core assembly can be understood as a collection of related components that implement the main functions of the wearable device, for example, the core assembly can support the implementation of functions such as sound signal collection, electrical signal conversion processing, device on-off, volume adjustment, power supply, etc. The core assembly is arranged in the shell assembly 100 to form a complete functional structure with the shell assembly 100. For the sake of distinction and description, the combination of the shell assembly 100 and the core assembly is defined as the device main body.

[0074] The speaker device can be understood as a collection of related components that implement the sound signal playing function of the wearable device. In some embodiments, the speaker device is connected and arranged with the device main body, that is, the speaker device is connected and arranged outside the shell assembly 100.

[0075] Exemplarily, referring to FIG. 1, the speaker device is an ear speaker, which comprises a speaker assembly 810 and a wearing assembly 820; wherein the speaker assembly 810 is arranged in a structure form capable of being adaptively inserted into an ear canal of a user, and mainly plays a role of playing a sound signal to the user; the wearing assembly 820 is arranged between the speaker assembly 810 and the shell assembly 100 in a form of electrically connecting the speaker assembly 810 and the core assembly, and mainly serves to establish a signal connection relationship between the core assembly and the speaker assembly 810.

[0076] The wearing assembly 820 can adopt a flexible cable with a signal transmission function, or other wires with both signal transmission function and shape memory function. One end of the wearing assembly 820 is fixed and electrically connected with the speaker assembly 810, and the other end of the wearing assembly 820 can be connected to the shell assembly 100 in a detachable or non-detachable manner and electrically connected with the core assembly.

[0077] With the wearing assembly 820, the device body can be stably worn on the ear of the user, and the speaker assembly 810 can be inserted into the ear canal of the user; the external sound signal can be collected by the device body (specifically, the core assembly), and the sound signal can be converted into an electric signal and output to the speaker assembly 810, so that the corresponding sound signal can be played by the speaker assembly 810 to realize the hearing aid function of the wearable device.

[0078] In other embodiments, the speaker device can also be configured in other forms in the wearable device, for example, referring to the core assembly arranged directly inside or outside the shell assembly 100 to form a wearable device with different structure forms or different functions; that is, by selecting and configuring the structure relationship between the speaker device, the device body and the two, other structure forms of hearing aids or earphones, glasses and other types of wearable devices can also be constructed.

[0079] It can be understood that, when the wearable device is in a powered-on state, the conversion between the sound signal (such as a mechanical vibration signal) and the electric signal can be realized by the cooperation of the core assembly and the speaker device, so that the user can hear the sound through the ear. Generally, the mechanical vibration can act on the tympanic membrane of the user and then act on the auditory nerve based on the air conduction principle and mainly through air as a medium; the mechanical vibration can also directly act on the auditory nerve of the user through the bone and tissue of the user as a medium based on the bone conduction principle; for the sound heard by the user, the former can be referred to as "air conduction sound", and the latter can be referred to as "bone conduction sound".

[0080] Based on this, by selecting and configuring the specific functional structures of the core assembly and the loudspeaker device, the wearable device can form air conduction sound, bone conduction sound, or both air conduction sound and bone conduction sound.

[0081] In the following, the device body and its related structures are described mainly by taking the wearable device as an air conduction hearing aid as an example. Other components of the wearable device (such as the loudspeaker device) can refer to the prior art. However, it should be noted that the wearable device can also be a headset, glasses, or other devices.

[0082] To more clearly and specifically describe the structure of the device body, based on the outer contour shape of the device body, three directions intersecting or perpendicular to each other are defined in this document, namely, the "first direction", the "second direction", and the "third direction".

[0083] Exemplarily, in a certain natural placement state of the wearable device, the first direction can refer to the length direction of the device as a whole, the second direction can refer to the thickness direction of the device as a whole, and the third direction can refer to the width direction of the device as a whole.

[0084] Exemplarily, in a state where the wearable device is normally worn between the back of the ear and the head, with the user as the reference basis, the first direction can refer to the up-down direction of the user, the second direction can refer to the front-rear direction of the user, and the third direction can refer to the left-right direction of the user.

[0085] In one embodiment, referring to FIGS. 1-7, the shell assembly 100 includes a first shell 110 and a second shell 120; the first shell 110 and the second shell 120 are opposite to each other and connected in cooperation to enclose a receiving cavity 100a in the interior of the shell assembly 100 (or between the first shell 110 and the second shell 120); the core assembly is arranged in the receiving cavity 100a; wherein at least a part of the core assembly 100 is connected and arranged on the first shell 110, and at least another part of the core assembly 100 is connected and arranged on the second shell 120.

[0086] Exemplarily, the core assembly includes a control board assembly 200, a microphone assembly 300, a key assembly 400, a first interface assembly 500, a second interface assembly 600, and a battery assembly 700; for the convenience of distinguishing and describing, the functional members in the core assembly connected with the first shell 110 are defined as the first assembly, and the functional members in the core assembly connected with the second shell 120 are defined as the second assembly. Wherein, the first assembly can include the control board assembly 200, the microphone assembly 300, and the key assembly 400; the second assembly can include the first interface assembly 500, the second interface assembly 600, and the battery assembly 700.

[0087] The microphone assembly 300 is electrically connected to the control board assembly 200 and is fixed to the first shell 110. The microphone assembly 300 is mainly used to collect sound signals outside the device (for example, outside the shell assembly 100). For example, the microphone assembly 300 itself is caused to produce mechanical vibration due to external environmental sound, so that the microphone assembly 300 collects sound signals.

[0088] The control board assembly 200 mainly plays a role in regulating and managing the wearable device. For example, the control board assembly 200 can receive sound signals collected by the microphone assembly 300, and then convert the sound signals into electrical signals and output to the loudspeaker device (for example, the loudspeaker assembly 810), so as to play the sound signals to the user through the loudspeaker device.

[0089] The key assembly 400 is movably connected to the first shell 110 and is arranged in cooperation with the control board assembly 200. Through cooperation between the key assembly 400 and the control board assembly 200, the input of a preset instruction can be realized. For example, the key assembly 400 can input an instruction for controlling the wearable device to start or shut down, an instruction for adjusting the volume, or other instructions to the control board assembly 200.

[0090] The first interface assembly 500, the second interface assembly 600, and the battery assembly 700 are connected to the second shell 120 and are electrically connected to the control board assembly 200. For example, an electrical signal connection relationship is established between the control board assembly 200 and the first interface assembly 500, the second interface assembly 600, and the battery assembly 700 through a wire assembly. The first interface assembly 500 mainly plays a role in connecting the loudspeaker device in the device main body. For example, the first interface assembly 500 is detachably connected to the wearing assembly 820 in a pluggable form, so as to establish a signal connection relationship between the loudspeaker assembly 810 and the control board assembly 200, so that the loudspeaker assembly 810 can produce or play sound signals due to electrical signals provided by the control board assembly 200.

[0091] The second interface assembly 600 is mainly used to connect an external regulating and controlling device (for example, a mobile phone, a computer, etc.) to perform data transmission between the external regulating and controlling device and the wearable device. For example, the external regulating and controlling device can adaptively adjust the working mode, the working parameter, the volume size, etc. of the wearable device according to the needs of the user. The battery assembly 700 is mainly used to supply power to the power-consuming components in the wearable device, so as to provide support for the normal working of the wearable device.

[0092] In some embodiments, other functional components can be added to the movement core assembly or some functional assemblies can be omitted. For example, the first interface assembly 500 can be omitted, and the loudspeaker assembly 810 can be directly connected to the control board assembly 200 through the wearing assembly 820. For another example, the second interface assembly 600 can be replaced by a wireless communication module, and data transmission between the wearable device and the external regulating and controlling device can be performed through the wireless communication module.

[0093] That is, the movement assembly can include one or more of the control board assembly 200, the microphone assembly 300, the button assembly 400, the first interface assembly 500, the second interface assembly 600, and the battery assembly 700.

[0094] In some embodiments, based on the structure form inside the shell assembly 100, the functional components in the first assembly and the second assembly can also be arranged in each other, for example, the first interface assembly 500 belongs to the first assembly and is connected to the first shell 110.

[0095] That is, the control board assembly 200, the microphone assembly 300, the button assembly 400, the first interface assembly 500, the second interface assembly 600, and the battery assembly 700, etc. can be selectively connected to the first shell 110 or the second shell 120 according to the structure layout and functional configuration of the shell assembly 100 or the device body.

[0096] It should be noted that the description of the "wire assembly" is introduced in this paper, which can be a wire, a wire, a flexible printed circuit (Flexible Printed Circuit, FPC), etc. to adapt to the internal structure of the shell assembly 100 and the spatial arrangement relationship between the related functional components, thereby establishing a flexible electrical connection relationship between the related functional components.

[0097] Based on this, by taking the first shell 110 and the second shell 120 as the mounting carrier of the plurality of functional components inside the device, the movement assembly can be dispersedly arranged at different parts of the shell assembly 100.

[0098] On the one hand, compared with the related art which uses the internal skeleton of the shell assembly 100 as the mounting carrier of the movement assembly, the present application can fully utilize the shell structure and space, reduce the number of internal components of the device, thereby facilitating the miniaturization and lightweight design of the wearable device.

[0099] On the other hand, based on the structure form of the dispersed arrangement of the movement assembly, not only can the wearable device be quickly disassembled and combined, but also by disassembling the first shell 110 and the second shell 120, the first assembly and the second assembly can be disassembled, maintained, recycled, etc.

[0100] In one embodiment, referring to FIGS. 4-7, the first shell 110 and the second shell 120 both adopt a shell structure with an opening, and the first shell 110 and the second shell 120 are connected in the form of opening each other in the second direction to form a containing cavity 100a.

[0101] As for the movement assembly, the first assembly (e.g. the control board assembly 200, the microphone assembly 300, the button assembly 400, etc.) is connected to the inner wall of the first shell 110 so that at least part of the first assembly is accommodated in the shell space of the first shell 110; and the second assembly (e.g. the first interface assembly 500, the second interface assembly 600, the battery assembly 700, etc.) is connected to the inner wall of the second shell 120 so that at least part of the second assembly is accommodated in the shell space of the second shell 120.

[0102] Firstly, by connecting the first assembly to the inner wall of the first shell 110 and connecting the second assembly to the inner wall of the second shell 120, the connection structure between the movement assembly and the shell assembly 100 can be prevented from affecting the appearance profile of the device main body and improving the appearance aesthetics and wearability of the device main body.

[0103] Secondly, by accommodating the first assembly and the second assembly in the shell space of the first shell 110 and the second shell 120, the first assembly or the second assembly can be protected from damage caused by bumping before the shell assembly 100 is assembled.

[0104] Thirdly, by setting the first shell 110 and the second shell 120 as the shell structure with a certain volume space inside and an opening, the first shell 110 and the first assembly and the second shell 120 and the second assembly can be assembled respectively, and after the wiring of the wire assembly is completed, the assembly of the device main body can be completed conveniently and quickly.

[0105] In some embodiments, the first shell 110 can adopt the shell structure with an opening, and the second shell 120 can adopt the cover plate structure; the second shell 120 is arranged on the first shell 110 in the form of covering the opening of the first shell 110 to form the accommodation cavity 100a with the first shell 110; and as for the movement assembly, the first assembly is connected to the inner wall of the first shell 110 and accommodated in the shell space of the first shell 110; the second assembly is connected to the side of the second shell 120 facing the first shell 110; after the first shell 110 and the second shell 120 are combined, the second assembly is equivalent to being accommodated in the shell space (i.e. the accommodation cavity 100a) of the first shell 110. Of course, the first shell 110 can adopt the cover plate structure, and the second shell 120 can adopt the shell structure with an opening.

[0106] Therefore, the shell assembly 100 is combined in the form of the shell structure cooperating with the cover plate structure, which not only facilitates the rapid assembly of the device main body, but also can form wearable devices with different structural forms or assembly modes to meet different application requirements.

[0107] In one embodiment, referring to FIGS. 4-7, an assembly structure is provided between the first housing 110 and the second housing 120, which is mainly used to assemble and fix the first housing 110 provided with the first assembly and the second housing 120 provided with the second assembly into an integrated whole, so as to roughly form a complete outer contour structure of the device main body (i.e., the housing assembly 100), so that the wearable device or the device main body can be moved, carried, worn, operated and used by means of the housing assembly 100.

[0108] The assembly structure can adopt different structures according to the connection form between the first housing 110 and the second housing 120, for example, the assembly structure can be a related structure suitable for realizing the connection form of gluing, welding, etc. between the first housing 110 and the second housing 120, and for another example, the assembly structure can also be a related structure suitable for realizing the detachable connection form of clamping, locking, etc. between the first housing 110 and the second housing 120.

[0109] Exemplarily, referring to FIGS. 4-7, the assembly structure includes a first fixing structure and a first positioning structure; wherein the first fixing structure is mainly used to stably fix the first housing 110 and the second housing 120 into an integrated whole; the first positioning structure is mainly used to position the relative position between the first housing 110 and the second housing 120, so as to provide support for quickly and accurately assembling the first housing 110 and the second housing 120, and at the same time cooperate with the first fixing structure to enhance the structural combination strength of the first housing 110 and the second housing 120.

[0110] The first fixing structure includes a support arm 131 and a fixing pin 132; wherein the support arm 131 is provided protruding from the inner wall surface of the second housing 120, for example, the support arm 131 is an integrated structure with the second housing 120; the fixing pin 132 cooperates with the support arm 131.

[0111] The first positioning structure includes a first positioning protrusion 141 and a first positioning slot hole 142; wherein the first positioning protrusion 141 is provided protruding from the inner wall surface of the first housing 110, and the first positioning protrusion 141 is an integrated structure with the first housing 110; the first positioning slot hole 142 is integrally formed in the second housing 120 at a position corresponding to the first positioning protrusion 141.

[0112] In the process of assembling the first shell 110 and the second shell 120 to form the shell assembly 100, the first positioning protrusion 141 can be inserted into the first positioning slot 142 in advance by virtue of the positioning relationship between the first positioning protrusion 141 and the first positioning slot 142, so as to define the relative position of the first shell 110 and the second shell 120, for example, the open end faces of the first shell 110 and the second shell 120 abut each other, so that the first space and the second space are in communication to form the accommodating cavity 100a (at this time, the support arm 131 is located in the accommodating cavity 100a).

[0113] Then, the fixing pin 132 is inserted into the interior of the shell assembly 100 from the exterior of the shell assembly 100 through the position of the first shell 110 corresponding to the support arm 131 (for example, a pin hole structure can be arranged at the position of the first shell 110 corresponding to the support arm 131), so as to penetrate and fix the first shell 110 and the support arm 131 into an integrated whole, so as to finally realize the detachable assembly and fixation between the first shell 110 and the second shell 120.

[0114] In some embodiments, the support arm 131 and the fixing pin 132, the first positioning protrusion 141 and the first positioning slot 142 can also be arranged in a position exchange manner; for example, the support arm 131 protrudes from the inner wall of the first shell 110, and the first positioning protrusion 141 protrudes from the inner wall of the second shell 120.

[0115] By virtue of the mutual cooperation of the first fixing structure and the first positioning structure, the assembly and fixation of the first shell 110 and the second shell 120 can be realized conveniently, quickly and accurately, so as to effectively enhance the structural stability of the shell assembly 100 (or the equipment shell), and provide structural support for the detachable assembly of the equipment main body or the shell assembly 100.

[0116] For example, in the process of assembling the equipment main body or the shell assembly 100, the first positioning protrusion 141 can be inserted into the corresponding first positioning slot 142 first, and then the fixing pin 132 is inserted by virtue of the cooperation relationship between the support arm 131 and the fixing pin 132, so as to finally assemble and fix the first shell 110 and the second shell 120 to form the shell assembly 100; in this way, the assembly accuracy of the first shell 110 and the second shell 120 can be ensured.

[0117] For example, when the equipment main body needs to be disassembled for maintenance, the shell assembly 100 can be disassembled by pulling out the fixing pin 132, so as to check and maintain the structure and related components inside the equipment main body.

[0118] In some embodiments, the first fixing structure and the first positioning structure can also adopt other structural forms.

[0119] For example, a plurality of snap structures are arranged on the first shell 110 and the second shell 120 to replace the first fixing structure and the first positioning structure, so as to realize the assembly and fixation of the first shell 110 and the second shell 120.

[0120] For another example, a protruding shaft structure is arranged on the inner wall of the first shell 110 at a position corresponding to the support arm 131, and a pin hole structure is arranged on the support arm 131 to be inserted by the protruding shaft structure, so as to form the first fixing structure, thereby realizing the positioning and fixation of the first shell 110 and the second shell 120 from different positions and different directions under the cooperation of the first positioning structure.

[0121] In some embodiments, the first fixing structure can be omitted, and one or more first positioning structures are arranged to preliminarily position the first shell 110 and the second shell 120, and then the first shell 110 and the second shell 120 are finally fixed by means of gluing, welding or the like.

[0122] Of course, the first positioning structure can also be omitted, and a plurality of groups of support arms 131 and fixing pins 132 are arranged to fixedly connect the first shell 110 and the second shell 120 from different positions. All these will not be described here.

[0123] In one embodiment, referring to FIGS. 4 and 5, the first shell 110 and the second shell 120 are connected to each other in the second direction to form the shell assembly 100, and the first fixing structure and the first positioning structure are arranged at the two opposite ends of the shell assembly 100 in the first direction. For the convenience of description, the two opposite ends of the shell assembly 100 in the first direction or the length direction can be defined as the first end and the second end of the shell assembly 100. In the normal wearing state of the wearable device, the first end of the shell assembly 100 can be the upper end of the shell assembly 100, and the second end of the shell assembly 100 can be the bottom end of the shell assembly 100. The first fixing structure is arranged at the first end of the shell assembly 100, and the first positioning structure is arranged at the second end of the shell assembly 100.

[0124] By arranging the first fixing structure and the first positioning structure at the two opposite ends of the shell assembly 100, the first shell 110 and the second shell 120 can be preliminarily positioned and combined by means of the first positioning structure in the assembly process, and then the first shell 110 and the second shell 120 are fixed by means of the cooperation of the fixing pin 132 and the support arm 131. In this way, it is beneficial for the assembly personnel to quickly and accurately identify the assembly direction of the first shell 110 and the second shell 120, thereby improving the assembly efficiency of the shell assembly 100 or the device main body. At the same time, it is also convenient to check and maintain the internal structure and related functional components of the shell assembly 100 by disassembling the shell assembly 100.

[0125] In some embodiments, the control board assembly 200, the microphone assembly 300, etc. are connected with the inner wall of the first shell 110, the first interface assembly 500, the battery assembly 700, etc. are connected with the inner wall of the second shell 120, and the first shell 110 and the second shell 120 both adopt a shell structure; the support arm 131 is arranged on the side of the first shell 110 in the second direction and protrudes from the inner wall of the second shell 120; the fixing pin 132 is arranged in the first shell 110 and the support arm 131 in the third direction; correspondingly, the first positioning protrusion 141 is arranged on the side of the second shell 120 in the second direction and protrudes from the inner wall or the open end surface of the second shell 120.

[0126] Thus, based on the differential arrangement of the support arm 131 and the first positioning protrusion 141 in the direction, the combination of the second shell 120 and the second assembly can be regarded as a mounting body, and the assembly personnel can quickly and accurately assemble the combination of the first shell 110 and the first assembly to the mounting body.

[0127] Hereinafter, the device main body and the related structure will be described mainly by taking the first shell 110 and the second shell 120 both adopting a shell structure as an example.

[0128] For the convenience of distinguishing and description, the two shell walls of the first shell 110 opposite to each other in the first direction are defined as the first shell wall 110a and the second shell wall 110b, the two shell walls opposite to each other in the third direction are defined as the second shell wall 110c and the third shell wall 110d, and the shell wall connecting the first shell wall 110a, the second shell wall 110b, the third shell wall 110c and the fourth shell wall 110d in the second direction is defined as the fifth shell wall 110e.

[0129] The two shell walls of the second shell 120 opposite to each other in the first direction are defined as the sixth shell wall 120a and the seventh shell wall 120b, the two shell walls opposite to each other in the third direction are defined as the eighth shell wall 120c and the ninth shell wall 120d, and the shell wall connecting the sixth shell wall 120a, the seventh shell wall 120b, the eighth shell wall 120c and the ninth shell wall 120d in the second direction is defined as the tenth shell wall 120e.

[0130] The first shell wall 110a and the sixth shell wall 120a combine to form a first side wall of the shell assembly 100, the second shell wall 110b and the seventh shell wall 120b combine to form a second side wall of the shell assembly 100, the fifth shell wall 110e and the tenth shell wall 120e can be understood as a third side wall and a fourth side wall of the shell assembly 100 opposite to each other in the second direction, the third shell wall 110c and the eighth shell wall 120c combine to form a fifth side wall of the shell assembly 100, and the fourth shell wall 110d and the ninth shell wall 120d combine to form a sixth side wall of the shell assembly 100. It can be understood that the first side wall, the second side wall, the third side wall, the fourth side wall, the fifth side wall and the sixth side wall of the shell assembly 100 surround the accommodation cavity 100a.

[0131] In some embodiments, referring to FIGS. 1-3 and 5, the shell assembly 100 or the outer contour structure of the device body adopts a profiled structure, so that the shell assembly 100 or the device body can adapt to the physiological structure between the back of the ear and the head, and thus can be worn in the form of being clamped or hung on the ear.

[0132] That is, in the normal wearing state of the wearable device, for example, in the state that the device body is hung on the back of the user's ear by means of the wearing assembly 820, and the speaker assembly 810 is inserted into the user's ear canal: the first side wall is a side wall facing the front side of the user in the first direction, the second side wall is a side wall facing the lower side of the user's ear in the first direction, the third side wall is a side wall away from the region where the user's head and the back of the ear meet in the second direction, the fourth side wall is a side wall facing or contacting the region where the user's head and the back of the ear meet in the second direction, the fifth side wall is a side wall facing or contacting the back of the user's ear in the third direction, and the sixth side wall is a side wall facing or contacting the user's head in the third direction.

[0133] In this case, the size of the shell assembly 100 in the first direction can be generally set to be greater than the size of the shell assembly 100 in the second direction and the third direction, and the third side wall and the fourth side wall can be generally set to have an arc surface structure that can adapt to the physiological structure of the region where the back of the ear and the head meet. In terms of the geometric center line of the shell assembly 100 in the first direction, the geometric center line can be generally set to be an arc segment.

[0134] In some embodiments, the core assembly includes the control board assembly 200, the microphone assembly 300, the key assembly 400, the first interface assembly 500, the second interface assembly 600 and the battery assembly 700, and the layout of the core assembly on the shell assembly 100 will be described below.

[0135] Referring to FIG. 2, the control board assembly 200 is arranged inside the shell assembly 100, for example, fixedly connected with the third side wall (i.e., the fifth shell wall 110e); the microphone assembly 300 can be a collection of relevant functional devices capable of forming "air conduction sound", and the microphone assembly 300 is fixedly arranged at the third side wall and in air communication with the outside of the shell assembly 100 at the third side wall.

[0136] Exemplarily, the third side wall (i.e., the fifth shell wall 110e) can be provided with a sound pickup hole 110f corresponding to the position of the microphone assembly 300, and the sound pickup hole 110f is arranged in communication with the microphone assembly 300, and the external sound signal is conducted to the microphone assembly 300 by air as a medium, so as to make the microphone assembly 300 collect the sound signal by generating mechanical vibration.

[0137] Exemplarily, a sound guide pipe can also be arranged in the accommodating cavity 100a, and the microphone assembly 300 is in communication with the outside of the shell assembly 100 through the sound guide pipe, so as to realize the collection of the sound signal.

[0138] In some embodiments, referring to FIG. 2, the number of microphone assemblies 300 is two, and the two microphone assemblies 300 are arranged on opposite sides of the control board assembly 200 in the first direction; in terms of the device main body, the two microphone assemblies 300 can collect sound signals from different directions.

[0139] Referring to FIGS. 2 and 3, the key assembly 400 is arranged in the accommodating cavity 100a in the form of movable connection (for example, rotary connection, sliding connection, etc.) with the inner wall of the first shell 110, and the key assembly 400 is at least partially exposed to the third side wall.

[0140] For example, the key assembly 400 is arranged on the side of the control board assembly 200 in the second direction towards the third side wall, and the key window 110g is provided through the third side wall corresponding to the position of the key assembly 400, and the key assembly 400 is exposed and protrudes from the third side wall through the key window 110g.

[0141] By applying a pressing force to the key assembly 400 towards the side of the control board assembly 200, the key assembly 400 can be pressed to press the key switch on the control board assembly 200, so as to realize the input of the preset instruction.

[0142] In some embodiments, the key assembly 400 can also include a switch component capable of generating an electrical signal, and the key assembly 400 is electrically connected with the control board assembly 200, and the instruction information is input to the control board assembly 200 by triggering the key assembly 400.

[0143] Referring to FIG. 2, FIG. 6 and FIG. 12, the first interface assembly 500 is fixedly connected with the second housing 120 (for example, fixed to the fourth side wall) and arranged in the accommodating cavity 100a in a form of at least partially exposed to the first side wall; for example, a first connecting port 120f can be provided through the first side wall, and the interface end of the first interface assembly 500 can be arranged in the first direction and communicated with the first connecting port 120f, and the interface end of the first interface assembly 500 can also extend into the first connecting port 120f and further extend out of the housing assembly 100 from the first connecting port 120f.

[0144] Correspondingly, the interface structure capable of pluggable and suitable connection with the first interface assembly 500 can be provided on the speaker device (in particular, the end of the wearing assembly 820 away from the speaker assembly 810), and the interface structure and the first interface assembly 500 are used to fix the speaker device and the device main body and realize the electrical connection between the speaker device and the movement assembly (for example, the control board assembly 200).

[0145] Referring to FIG. 2, FIG. 6 and FIG. 12, the second interface assembly 600 is fixedly connected with the second housing 120 (for example, fixed to the fourth side wall) and arranged in the accommodating cavity 100a in a form of at least partially exposed to the fifth side wall or the sixth side wall; for example, a second connecting port 120g can be provided through the fifth side wall (for example, the eighth housing wall 120c), and the interface end of the second interface assembly 600 can be arranged in the third direction and communicated with the second connecting port 120g, and the interface end of the second interface assembly 600 can also extend into the second connecting port 120g. In the wearable device application stage, the second interface assembly 600 can be used to connect external control devices such as mobile phones and computers, so as to adaptively adjust the working mode and working parameters of the wearable device according to the user's own needs.

[0146] Referring to FIG. 2 and FIG. 4, the battery assembly 700 can be fixedly connected with the second housing 120 or movably connected with the second housing 120; for example, a battery window 120h can be provided at the region where the second side wall and the fourth side wall meet, and the battery assembly 700 is movably connected with the second housing 120, so that the battery assembly 700 can be taken in and out of the accommodating cavity 100a through the battery window 120h by rotating the battery assembly 700, so as to replace the battery.

[0147] Therefore, by dispersing the parts of the movement assembly at different positions or different orientations of the housing assembly 100, the structure and space of the housing assembly 100 can be more reasonably utilized, the performance of the device is ensured, and the wearable device is convenient to operate.

[0148] For example, by arranging the first interface assembly 500 and the battery assembly 700 at opposite ends of the device body in the first direction, the key assembly 400 is arranged in the first direction at a position between the first interface assembly 500 and the battery assembly 700; on the one hand, not only is it convenient to connect a speaker device (for example, the wearing assembly 820) through the first interface assembly 500, but it is also convenient to replace the battery in the battery assembly 700; on the other hand, in the wearing state of the device, the key assembly 400 can be located at approximately the middle of the rear side or the lower side of the rear side of the device body, so that it is not only convenient to operate the key assembly 400, but also avoids structural interference of the first interface assembly 500 and the battery assembly 700 on the key assembly 400.

[0149] For another example, by arranging the two microphone assemblies 300 at opposite sides of the key assembly 400 or the control board assembly 200 in the first direction, the arc surface structure of the third side wall can be used to make the sound pickup holes 110f corresponding to the two microphone assemblies 300 face different directions, so that the external sound signals can not be shielded by the user's body parts, and the sound signal collection effect of the microphone assemblies 300 is ensured.

[0150] In the embodiment in which the shell assembly 100 adopts a profiled structure, the size of the shell assembly 100 in the third direction can be gradually reduced from the side where the second side wall is located to the side where the first side wall is located; that is, the size of the first end of the shell assembly 100 in the third direction is smaller than the size of the second end of the shell assembly 100 in the third direction. In this way, the width of the end of the device body in the first direction for connecting the speaker (that is, the end where the first interface assembly 500 is located) is smaller than the width of the end where the battery assembly 500 is located, so that the space size requirement of the battery assembly 500 on the shell assembly 100 can be met.

[0151] In some embodiments, the shell assembly 100 is made of polyimide (PI) material; for example, the first shell 110 and the second shell 120 are both made of an integral structure of polyimide material, and are combined with each other to form the shell assembly 100.

[0152] Compared with the related art, the shell of the wearable device is made of polycarbonate (PC) material, ABS plastic (that is, a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S)), and the like; in the embodiment, based on the characteristics of good biocompatibility and mechanical strength of the polyimide material, the structure form (including the appearance form) of the shell assembly 100 is more stable, and the thickness of the shell is thinner, which is conducive to miniaturization and light weight of the wearable device, and enhances the stability of the overall structure of the shell assembly 100.

[0153] In one embodiment, referring to FIGS. 8-10, the core assembly includes a microphone assembly 300, and the first housing 110 is provided with a sound pickup channel 110f which penetrates the fifth housing wall 110e to enable the accommodation cavity 100a to communicate with the outside of the housing assembly 100. The microphone assembly 300 can be understood as a collection of devices capable of forming "air conduction sound", which is arranged in the accommodation cavity 100a and fixed to the inner wall (for example, the fifth housing wall 110e) of the first housing 110, and the sound inlet channel of the microphone assembly 300 is in sealed communication with the sound pickup channel 110f.

[0154] Exemplarily, referring to FIG. 9, the microphone assembly 300 includes a first circuit board 310, a microphone 320, and a protective net 330; the protective net 330 is fixed to the inner surface of the fifth housing wall 110e in the form of covering the sound outlet end of the sound pickup channel 110f, for example, the protective net 330 is fixed to the fifth housing wall 110e by adhesive bonding; the first circuit board 310 is fixed to the side of the protective net 330 opposite to the sound pickup channel 110f (for example, the first circuit board 310 is fixed to the protective net 330 by adhesive bonding), and the microphone 320 is arranged on the side of the first circuit board 310 opposite to the protective net 330, and the first circuit board 310 is provided with a sound guide channel 310a corresponding to the sound inlet channel of the microphone 320.

[0155] Among them, the microphone 320 is the main component for collecting sound signals in the microphone assembly 300, and the first circuit board 310 is the mounting carrier of the microphone 320, and the electrical signal connection relationship between the microphone 320 and the control board assembly 200 is established through the first circuit board 310.

[0156] Therefore, using the first housing 110 as the mounting carrier of the microphone assembly 300 can not only make full use of the structural space of the housing assembly 100, but also reduce the number of related components, thereby providing support for the lightweight and miniaturization of wearable devices. By using the sealed communication relationship between the microphone assembly 300 and the sound pickup channel 110f, external sound signals can enter the sound inlet channel of the microphone assembly 300 through the sound pickup channel 110f with air as the medium to cause mechanical vibration of the related devices of the microphone assembly 300, thereby realizing the collection of external sound signals through the collection and conversion of mechanical vibration signals.

[0157] In addition, based on the cooperation between the first circuit board 310 and the protective net 330, the microphone 320 is stably fixed to the first shell 110, and the sound inlet channel of the microphone 320 can be coaxially and sealingly communicated with the sound guide hole 310a and the sound pickup hole 110a, and the protective net 330 can prevent the water, dust and other pollutants outside the device from invading the microphone assembly 300 through the sound pickup hole 110f, thereby providing protection for the normal work of the microphone assembly 300.

[0158] In other embodiments, the microphone assembly 300 can also adopt other structural forms, for example, the protective net 330 is omitted, the microphone 320 is arranged on the side of the first circuit board 310 facing the sound pickup hole 110f, and the sound inlet channel of the microphone 320 can be directly sealingly communicated with the sound pickup hole 110f by means of the structural relationship between the first circuit board 310 and the first shell 110.

[0159] It should be noted that those skilled in the art should know the basic working principle of the air conduction microphone, and therefore the specific process and principle of the microphone assembly 300 collecting sound signals are not described here.

[0160] In one embodiment, referring to FIGS. 2 and 8, the number of the sound pickup holes 110f and the microphone assemblies 300 is two, the sound inlet channels of the two sound pickup holes 110f and the two microphone assemblies 300 are one-to-one corresponding and sealingly communicated, and taking the sound pickup hole 110f as an example, the sound inlet ends of the two sound pickup holes 110f are arranged at intervals from each other, thereby cooperating with the microphone assembly 300 to collect external sound signals at different positions or different orientations.

[0161] Exemplarily, in some embodiments, based on the arc surface structure form of the third side wall (i.e., the fifth shell wall 110e) of the shell assembly 100, the sound inlet ends of the two sound pickup holes 110f are arranged at intervals in the first direction on the outer surface of the third side wall, thereby enabling the microphone assembly 300 to collect external sound signals from different orientations.

[0162] In other embodiments, according to the functional configuration or structural form of the microphone assembly 300, the two sound pickup holes 110f can also be sealingly communicated with the sound inlet channel of the same microphone assembly 300 at the same time, so as to meet different application requirements.

[0163] In one embodiment, referring to FIGS. 7, 9 and 10, the inner wall of the first shell 110 (e.g., the surface of the fifth shell wall 110e) is provided with a second fixing structure, which can include a fixing barrier 151 protruding from the inner wall surface of the first shell 110, e.g., the fixing barrier 151 is in one-piece structure with the first shell 110; a receiving groove is formed between the fixing barrier 151 and the inner wall surface of the fifth shell wall 110e; wherein at least part of the microphone assembly 300 (specifically, one end where the microphone 320 is located) is received and fixed in the receiving groove, and the sound outlet end of the sound pickup hole 110f is located within the contour range of the receiving groove.

[0164] On the one hand, the receiving groove formed between the fixing barrier 151 and the inner wall surface of the first shell 110 can facilitate quick positioning of the installation position of the microphone assembly 300, thereby providing support for the structural combination of the microphone assembly 300 and the first shell 110; on the other hand, the microphone assembly 300 can be restricted in the inner pre-set position (i.e., in the receiving groove) of the accommodating cavity 100a by the fixing barrier 151, thereby ensuring that the sound inlet channel of the microphone 320 can maintain coaxial sealed communication with the sound pickup hole 110f.

[0165] In other embodiments, the second fixing structure can also adopt other suitable structural forms, e.g., under the premise of ensuring the sealed communication of the microphone assembly 300 and the sound pickup hole 110f, the second fixing structure can be a buckle structure provided on the inner wall surface of the first shell 110, to buckle and fix the microphone assembly 300 at a position corresponding to the sound pickup hole 110f; or alternatively, the second fixing structure is a sink structure provided on the inner wall surface of the third side wall, and at least part of the microphone assembly 300 is inserted into the space of the second fixing structure. All of the above will not be repeated here.

[0166] In one embodiment, referring to FIGS. 2, 3, 8 to 10, the movement core assembly includes a control board assembly 200 and a microphone assembly 300; wherein the control board assembly 200 is fixedly connected with the inner wall of the first shell 110 and electrically connected with the microphone assembly 300, and is mainly used to receive the sound signal collected by the microphone assembly 300 and convert the sound signal into an electrical signal output to the loudspeaker device.

[0167] For example, the number of microphone assemblies 300 is set to two, and the two microphone assemblies 300 are arranged at opposite sides of the control board assembly 200 with a spacing therebetween and are respectively electrically connected with the control board assembly 200. For example, the control board assembly 200 is arranged between the two microphone assemblies 300 in the first direction.

[0168] More specifically, referring to FIGS. 8-10, the control board assembly 200 includes a second circuit board 210, which is configured to have a material hardness greater than that of the first circuit board 310, for example, the first circuit board 310 can be a flexible printed circuit board (FPC), and the second circuit board 210 can be a rigid printed circuit board (PCB).

[0169] For ease of description, the opposite ends of the first circuit board 310 in its length direction (or the first direction) are defined as the first end and the second end; wherein the microphone 320 and the like are arranged at the first end of the first circuit board 310; and the second end of the first circuit board 310 is fixedly connected (e.g., welded) to the second circuit board 210.

[0170] On the one hand, based on the structure of the soft board combined with the hard board formed between the microphone assembly 300 and the control board assembly 200. Firstly, it can enhance the compactness of the structural connection between the microphone assembly 300 and the control board assembly 200, and save the structural space of the accommodation cavity 100a. Secondly, based on the flexible deformation characteristics of the first circuit board 310 compared to the second circuit board 210, it can adapt to the structural form of the internal space of the shell assembly 100 (e.g., the inner surface side of the first shell 110), and flexibly adjust the relative installation position between the microphone assembly 300 and the control board assembly 200, for example, to facilitate the direct installation and fixation of the microphone assembly 300 on the first shell 110. Thirdly, it is convenient for disassembling the microphone assembly 300 and the control board assembly 200 to realize the recycling of important electronic components, such as the control chip in the control board assembly 200.

[0171] On the other hand, in some embodiments of the shell assembly 100 using a profiled structure, since the third side wall (i.e., the third shell wall 110e) adopts an arc surface structure, the control board assembly 200 and the microphone assembly 300 have different orientations or different height differences relative to the inner surface of the third side wall, and the connection form of the soft board combined with the hard board between the two can well adapt to the differences in installation position and installation form between the control board assembly 200 and the microphone assembly 300, to conveniently and accurately complete the installation and fixation of the control board assembly 200 and the microphone assembly 300.

[0172] In one embodiment, referring to FIGS. 7 and 10, the inner surface (specifically, the fifth shell wall 110e) of the first shell 110 is provided with a third fixing structure, which is mainly used to support and fix the second circuit board 210 at a predetermined position in the accommodation cavity 100a, so that the control board assembly 200 and the microphone assembly 300 maintain a sufficient spacing distance.

[0173] For example, referring to FIG. 7 and FIG. 10, the third fixing structure can include a plurality of support columns 161 protruding from the fifth shell wall 110e, and the plurality of support columns 161 are arranged at intervals around the geometric center line of the second circuit board 210; correspondingly, the second circuit board 210 is provided with a positioning through hole 210a corresponding to the position of the support column 161; the support column 161 is inserted into the positioning through hole 210a, and the second circuit board 210 or the control board assembly 200 can be supported and fixed on the first shell 110 in a manner of being spaced apart from the inner surface of the fifth shell wall 110e.

[0174] On the one hand, by means of the cooperation of the support column 161 and the positioning through hole 210a, a fixed interval distance can be formed between the control board assembly 200 and the microphone assembly 300, so as to avoid signal interference therebetween.

[0175] On the other hand, based on the support column 161, a certain structural gap can be formed between the second circuit board 210 and the inner wall of the first shell 110, so as to provide a structural space for assembling the key assembly 400 to the first shell 110; for example, the second circuit board 210 can be arranged transversely in the accommodating cavity 100a along the third direction (or the width direction of the device main body) (it can also be understood that the plane where the second circuit board 210 is located is substantially perpendicular to the third shell wall 110c and the fourth shell wall 110d), so as to utilize the structural gap between the second circuit board 210 and the fifth shell wall 110e as a structural mounting space and a moving space of the key assembly 400. In this way, it is convenient to control the overall width and thickness size of the device main body, and it is also convenient to fix and assemble the microphone assembly 300 and the control board assembly 200 to the first shell 110 in steps.

[0176] In other embodiments, the third fixing structure can also adopt other suitable structural forms, for example, the support column 161 protrudes from the second circuit board 210, and a slot structure is arranged on the inner wall surface of the first shell 110 for inserting and fixing the support column 161; details are not described herein.

[0177] In one embodiment, referring to FIG. 4 to FIG. 6, and combining with FIG. 10 and FIG. 12, the first limiting structure is further arranged between the first shell 110 and the second shell 120; on the one hand, the first limiting structure can limit the relative position between the first shell 110 and the second shell 120, and enhance the structural connection strength between the first shell 110 and the second shell 120; on the other hand, the first limiting structure can prevent the first shell 110 and the second shell 120 from being deformed at the joint therebetween, so as to avoid the control board assembly 200 (specifically, the second circuit board 210) being pressed due to the structural deformation of the shell.

[0178] Exemplarily, referring to FIGS. 4-6, the first shell 110 and the second shell 120 are both in a shell structure, and the surface of the first shell 110 and the second shell 120 that abuts against each other in the second direction is defined as an abutting surface; wherein the abutting surface of the first shell 110 is provided with a first limiting flange 171 protruding toward the side of the second shell 120 along the second direction, and the abutting surface of the second shell 120 is provided with a second limiting flange 172 protruding toward the side of the first shell 110 along the second direction.

[0179] In the assembled state of the shell assembly 100, the first limiting flange 171 is located on the side of the second limiting flange 172 that faces away from the accommodating cavity 100a in the third direction (i.e., with the accommodating cavity 100a as a reference, the first limiting flange 171 is located outside the accommodating cavity 100a).

[0180] By means of the second limiting flange 172 abutting against the first limiting flange 171 from the inside of the accommodating cavity 100a, a first limiting structure is formed, which can not only prevent the first shell 110 from being deformed in the third direction due to the performance of the material itself, thereby preventing the control board assembly 200 (specifically, the second circuit board 210) from being squeezed, but also enhance the structural connection strength of the first shell 110 and the second shell 120 at the abutting surface, reduce or eliminate the structural gap between the first shell 110 and the second shell 120, and ensure the integrity of the overall profile of the shell assembly 100.

[0181] In some embodiments, the first limiting structure can also be arranged between the abutting surfaces of the first shell 110 and the second shell 120 in other structural forms, for example, a flange is arranged on the abutting surface of the second shell 120, and a slot is arranged on the abutting surface of the first shell 110 corresponding to the position of the flange, and the flange is inserted into the slot in a position to form the first limiting structure, thereby also preventing the first shell 110 from being deformed in the third direction, thereby preventing the first shell 110 from squeezing the first assembly (for example, the control board assembly 200).

[0182] In some embodiments, for the same purpose of protecting the control board assembly 200, the first limiting flange 171 can also be located on the side of the second limiting flange 172 that faces the accommodating cavity 100a in the third direction, i.e., with the accommodating cavity 100a as a reference, the first limiting flange 171 is located inside the accommodating cavity 100a; by means of the first limiting flange 171 abutting against the second limiting flange 172 from the inside of the accommodating cavity 100a, the second shell 120 can be prevented from being deformed in the third direction to cause the opening to shrink, thereby squeezing the second assembly (for example, the first interface assembly 500, etc.) arranged on the second shell 120.

[0183] In some embodiments, the first limiting structure can include a flange and a slot, which are arranged on the joint surface of the first shell 110 and the second shell 120. The structure of the flange and the slot corresponding to each other can prevent the first shell 110 and the second shell 120 from deforming in the third direction, thereby protecting the first assembly and the second assembly from being squeezed by the shell.

[0184] In one embodiment, referring to FIGS. 4-6, the first limiting structure is arranged in multiple groups on the opposite sides of the accommodating cavity 100a in the third direction, for example, on the opposite sides of the second circuit board 210 in the third direction, so as to enhance the stability of the first limiting structure and prevent the first shell 110 from deforming.

[0185] Of course, the first limiting structure can also be arranged at intervals in the second direction, so as to limit the deformation of the shell from the third direction, the first direction, and other directions, thereby ensuring that the joint surfaces of the first shell 110 and the second shell 120 can stably abut each other.

[0186] In one embodiment, referring to FIGS. 4-6, the joint surface of the first shell 110 or the joint surface of the second shell 110 is further provided with a relief structure, which is mainly used to avoid part of the first assembly or the second assembly during the assembly of the first shell 110 and the second shell 120, so as to adapt to the space size requirement of the first assembly or the second assembly to the accommodating cavity 100a.

[0187] For example, the first limiting flange 171 is located on the side of the second limiting flange 172 opposite to the accommodating cavity 100a in the third direction. The relief structure can be a second relief gap 173 arranged on the second limiting flange 172, a groove structure arranged on the surface of the second limiting flange 172 facing the accommodating cavity 100a, or a structural gap between two adjacent second limiting flanges 172 in the first direction.

[0188] For example, the second relief gap 173 can be used to adapt to the contour size of the second circuit board 210 during the assembly of the first shell 110 and the second shell 120, so as to avoid or accommodate the part of the second circuit board 210 protruding outward from the shell assembly 100 in the third direction. In this way, the joint surfaces of the first shell 110 and the second shell 120 and the first limiting flange 171 and the second limiting flange 172 can effectively abut each other, and the control panel assembly 200 and other structures can be prevented from being squeezed or interfered.

[0189] In one embodiment, referring to FIGS. 8-11, the core assembly includes a control board assembly 200, a microphone assembly 300, and a key assembly 400; wherein the first housing 110 is provided with a key window 110g arranged through the fifth housing wall 110e, and the key window 110g communicates the accommodating cavity 100a with the outside of the housing assembly 100; for example, in an embodiment in which the core assembly includes two microphone assemblies 300, the key window 110g can be arranged between the two sound pickup holes 110f in the first direction; the key assembly 400 includes an operation key 410 movably connected with the inner wall of the first housing 110, and at least a portion of the operation key 410 is exposed outside the first housing 110 through the key window 110g and protrudes from the first housing 110.

[0190] For example, the control board assembly 200 is arranged on the side of the operation key 410 opposite to the key window 110g, and the control board assembly 200 is configured with a key switch for cooperating with the operation key 410. By moving the operation key 410 relative to the first housing 110, the operation key 410 can be used to press the key switch of the control board assembly 200, so that the input of the preset instruction can be realized.

[0191] By connecting the key assembly 400 to the first housing 110 and using the first housing 110 as a mounting carrier of the key assembly 400, the structure and space of the housing assembly 100 can be fully utilized, the number of components can be reduced, and support can be provided for the lightweight and small-sized design of the wearable device.

[0192] In one embodiment, referring to FIG. 11, a first pivot structure is arranged between the operation key 410 and the first housing 110, which can include a pivot protrusion 181 and a pivot slot 420. The pivot slot 420 is arranged on the two sides of the operation key 410 opposite in the third direction, and the pivot protrusion 181 protrudes from the inner wall (for example, the third housing wall 110c and the fourth housing wall 110d) of the first housing 110 and is arranged in the pivot slot 420 in a position opposite. Wherein, the two ends of the operation key 410 in the radial direction of the first pivot structure are respectively the first end and the second end of the operation key 410. Correspondingly, the key switch of the control board assembly 200 can be arranged at a position corresponding to the first end, the second end, or the first end and the second end of the operation key 410.

[0193] Therefore, based on the presence of the first pivot structure, the operation key 410 is rotated relative to the first housing 110 around the first pivot structure under the action of an external force, so that one of the first end and the second end of the operation key 410 protrudes from the first housing 110 or is raised relative to the first housing 110, and the other end is rotated towards the control board assembly 200 to press and trigger the corresponding key switch, thereby realizing the input of instruction information.

[0194] Exemplarily, referring to FIG. 11, the control board assembly 200 comprises a first circuit board 210, a first switch 220 and a second switch 230; wherein the first circuit board 210 is arranged at a side of the operation key 410 opposite to the key window 110g (e.g. supported and fixed to the first shell 110 by the support column 161), the first switch 220 and the second switch 230 are arranged at a side of the first circuit board 210 facing the operation key 410, and the first switch 220 corresponds to the first end of the operation key 410, and the second switch 230 corresponds to the second end of the operation key 410.

[0195] By pressing the first end of the operation key 410 towards the inside of the shell assembly 100, the first end of the operation key 410 can be pressed to touch the corresponding first switch 220 to realize the input of a preset instruction; in this process, the operation key 410 rotates relative to the first shell 110 around the first rotation shaft structure in a first preset direction (e.g. counterclockwise direction), and the second end of the operation key 410 is protruded from the outer surface of the first shell 110 or raised relative to the first end of the operation key 410.

[0196] Conversely, by pressing the second end of the operation key 410 towards the inside of the shell assembly 100, the second switch 220 can be triggered to realize the input of a preset instruction; in this process, the operation key 410 rotates relative to the first shell 110 around the first rotation shaft structure in a second preset direction opposite to the first preset direction (e.g. clockwise direction), and the first end of the operation key 410 is protruded from the outer surface of the first shell 110 or raised relative to the second end of the operation key 410.

[0197] In some embodiments, the first end and the second end of the operation key 410 can be symmetrically arranged about the first rotation shaft structure, so as to ensure the smoothness of the rotation of the operation key 410 relative to the first shell 110, and facilitate the selection or control of the positions of the key switches (e.g. the first switch 220 and the second switch 230) on the second circuit board 210.

[0198] Referring to FIG. 1, FIG. 2 and FIG. 8, in some embodiments in which the shell assembly 100 adopts a profiled structure, the third side wall (i.e. the fifth shell wall 110e) adopts an arc surface structure, and the plane where the control board assembly 200 (e.g. the second circuit board 210) is located is parallel to the rotation axis of the operation key 410 or the axis of the first rotation shaft structure. This makes it difficult to keep the heights of the first end and the second end of the operation key 410 protruded from the outer wall surface of the third side wall consistent, which can easily reduce the operation experience of the key assembly 400 and cause misoperation and other problems.

[0199] For the convenience of description, the first end of the operation key 410 can be understood as the end of the operation key 410 which is relatively lower in the first direction or the up-down direction of the user, with the device in the wearing state. Referring to FIG. 11, the outer surface of the first end of the operation key 410 is provided with a key protrusion 440 protruding outwardly towards the outside of the shell assembly 100, for example, the key protrusion 440 is arranged to protrude outwardly from the outer surface of the first end of the operation key 410 in the second direction.

[0200] In this way, by means of the key protrusion 440, not only can the height difference between the two ends of the operation key 410 relative to the shell assembly 100 be adjusted or compensated for, achieving the purpose of improving the operation experience, but also the risk of misoperation of the operation key 410 can be reduced.

[0201] In other embodiments, the key protrusion 440 can also be arranged to protrude outwardly from the second end of the operation key 410, or the first end and the second end of the operation key 410 can adopt different structural forms; in this way, the operation experience can be improved and the risk of misoperation can be reduced, thereby meeting different application requirements.

[0202] In some embodiments in which the first shell 110 and the second shell 120 are made of polyimide material, the key assembly 400 (specifically, the operation key 410) can also be made of an integral structure made of polyimide material, which can make the materials of the various components of the device main body tend to be consistent, which is not only conducive to the processing and manufacturing of related components, but also ensures that the related components have good biocompatibility and sufficient mechanical strength.

[0203] In one embodiment, referring to FIGS. 2, 12 to 14, the movement assembly includes a first interface assembly 500 and a second interface assembly 600, and the shell assembly 100 is provided with a first connecting port 120f and a second connecting port 120g which communicate the accommodation cavity 100a with the outside of the shell assembly 100; the first connecting port 120f is arranged through the first side wall (i.e., the first shell wall 110a and the sixth shell wall 120a) of the shell assembly 100, and the second connecting port 120g is arranged through the eighth shell wall 120c of the second shell 120; in the wearing state of the device, the first connecting port 120f is located at the top end of the shell assembly 100 in the up-down direction of the user and faces the front side of the user, and the second connecting port 120g is located at the middle part of the shell assembly 100 in the left-right direction of the user and faces the back side of the ear of the user.

[0204] The first interface assembly 500 comprises a first interface piece 510 and a first fixing piece 520. The first interface piece 510 has opposite interface ends and wiring ends. The first interface piece 510 is arranged in the accommodating cavity 100a with the interface ends facing the first connecting port 120f, so that the connector of the speaker device (in particular, the wearing assembly 820) can be inserted into the accommodating cavity 100a through the first connecting port 120f, and is connected to the first interface piece 510 in a pluggable and detachable or fixed manner. The wiring ends of the first interface piece 510 are used to connect the control board assembly 200, for example, by connecting the second circuit board 210 through a wire assembly.

[0205] The first fixing piece 520 cooperates with the first interface piece 510 to fix the first interface piece 510 to the second shell 120. For example, the fourth fixing structure 140 is arranged between the inner walls (in particular, the tenth shell wall 120e) of the second shell 120. The fourth fixing structure 140 can be arranged to restrict and fix the first fixing piece 520 (together with the first interface piece 510) on the second shell 120 from at least two different directions. The first interface piece 510 is fixed to the first fixing piece 520.

[0206] The second interface assembly 600 comprises a second interface piece 610 and a second fixing piece 620. The second interface piece 610 has opposite opening ends and wiring ends. The second interface piece 610 is arranged in the accommodating cavity 100a with the interface ends facing the second connecting port 120g. The connector of the external control device can be inserted into the accommodating cavity 100a through the second connecting port 120g and connected to the second interface piece 610 in a pluggable and detachable manner.

[0207] The second fixing piece 620 cooperates with the second interface piece 610 to fix the second interface piece 610 to the second shell 120. For example, the fifth fixing structure 150 is arranged on the inner walls (in particular, the tenth shell wall 120e) of the second shell 120. The second fixing piece 620 is fixedly connected to the fifth fixing structure 150 to clamp and fix the second interface piece 610 between the second fixing piece 620 and the inner walls of the second shell 120.

[0208] In some embodiments, the first fixing piece 520 or the second fixing piece 620 can be omitted. The first interface piece 510 or the second interface piece 610 can be clamped and fixed on the second shell 120 by arranging buckles or other structures on the inner walls of the second shell 120. Alternatively, the first interface piece 510 or the second interface piece 620 can be fixed on the second shell 120 by gluing, welding or other forms. All these will not be described here.

[0209] Therefore, by using the second shell 120 as a mounting carrier of the first interface assembly 500 and the second interface assembly 600, the structural space of the shell assembly 100 can be fully utilized, so that the structure of the wearable device is more compact, which is conducive to the lightweight and miniaturized design of the wearable device.

[0210] In some embodiments, as shown in FIG. 14, since the wearable device is usually not required to be connected with an external control device in a normal use state, in order to ensure the structural sealing or the integrity of the overall device, a sealing member 630 can be arranged at the second connecting port 120g. The sealing member 630 can be a sealing plug made of plastic material or other suitable structural components. By inserting or pulling out the sealing member 630 in or from the second connecting port 120g, the second connecting port 120g can be selectively closed and opened.

[0211] In some embodiments in which the speaker device is used as a consumable of the wearable device, or in some scenarios in which the speaker device is not assembled with the device body, the sealing member 630 can also be used to temporarily close the first connecting port 120f or the second connecting port 120g.

[0212] In some embodiments in which the shell assembly 100 is made of polyimide material, the first fixing member 520 and the second fixing member 620 are integrally formed of polyimide material. In this way, the materials of the components of the device body are close to each other, which is conducive to the processing and manufacturing of the related components, and ensures that the related components have good biocompatibility and sufficient mechanical strength.

[0213] As described above, the first interface assembly 500 or the second interface assembly 600 can be omitted; therefore, in some embodiments, the first interface assembly 500 or the second interface assembly 600 can be referred to as an interface assembly, the first interface member 510 or the second interface member 610 can be referred to as an interface member, and the first fixing member 520 or the second fixing member 620 can be referred to as a fixing member.

[0214] In one embodiment, as shown in FIGS. 2 to 4, 6 and 15, the movement assembly includes a battery assembly 700, and the shell assembly 100 is provided with a battery window 120h for communicating the accommodation cavity 100a with the outside of the shell assembly 100. For example, the battery window 120h can be arranged through the seventh shell wall 120b and the tenth shell wall 120e of the second shell 120. In terms of the shell assembly 100, the battery window 120h can be a strip-shaped window arranged through the second side wall and the fourth side wall. Therefore, in some embodiments, the width direction of the battery window 120h can be understood as the third direction of the shell assembly 100, and the length direction of the battery window 120h can be understood as a direction around the third direction of the shell assembly 100.

[0215] The battery assembly 700 comprises a battery holder 710 for accommodating the battery 730 and an electrode spring 720 for electrically connecting the control board assembly 200. As shown in FIG. 15, the battery holder 710 and the second housing 120 form a second pivot structure 750 and a locking structure 760. The second pivot structure 750 is used to establish a relatively rotatable structural connection between the battery holder 710 and the second housing 120, so that the battery holder 710 can rotate relative to the second housing 120 about the second pivot structure 750 (the axis of the second pivot structure 750 or the rotation axis of the battery holder 710 is the third direction), so that the battery holder 710 can enter and exit the accommodation cavity 100a through the battery window 120h. The locking structure 760 is used to lock the battery holder 710 to the second housing 120 (for example, so that the battery holder 710 remains in the accommodation cavity 100a), that is, the locking structure 760 can lock the battery holder 710 to the second housing 120 when the battery holder 710 closes the battery window 120h.

[0216] The electrode spring 720 is arranged in the accommodation cavity 100a and fixedly connected to the second housing 120. For example, the number of electrode springs 720 is two, and the two electrode springs 720 are arranged on the two sides of the battery window 120h in the third direction. When the battery holder 710 is locked to the second housing 120 by the locking structure 760, so that the battery 730 accommodated on the battery holder 710 is located in the accommodation cavity 100a, one end of each of the two electrode springs 720 can elastically abut the positive and negative electrodes of the battery 730, and the other end of each of the two electrode springs 720 can be electrically connected to the control board assembly 200 (for example, the second circuit board 210) through the wire assembly.

[0217] On the one hand, the second housing 120 is used as a mounting carrier of the battery assembly 700, and by dispersively arranging the components (i.e., the battery holder 710 and the electrode spring 720) of the battery assembly 700 in the second housing 120, the structural space of the second housing 120 or the housing assembly 100 can be fully utilized, which is conducive to the lightweight and miniaturized design of the wearable device.

[0218] On the other hand, by using the structure that the battery holder 710 can be rotated out of the housing assembly 100 through the battery window 120h, the battery 730 can be conveniently replaced. After the battery holder 710 is rotated into the accommodation cavity 100a, the structure of the battery window 120h can be adapted to achieve the closure of the battery window 120h, thereby maintaining the integrity of the outer contour structure of the device main body.

[0219] It should be noted that the description of the battery 730 is introduced in this embodiment only for the purpose of understanding the structural configuration and functional principle of the battery holder 710, and does not mean that the battery 730 is necessarily a component of the battery assembly 700. That is, in some embodiments, the battery 730 can be a component of the battery assembly 700; in other embodiments, the battery 730 can also be a consumable used with the wearable device.

[0220] In some embodiments in which the shell assembly 100 adopts a profiled structure, since the battery window 120h is a strip-shaped window provided through the second side wall and the fourth side wall of the shell assembly 100, the length trajectory of the battery window 120h is substantially an arc segment; the battery holder 710 can be configured to adapt to the arc shape of the battery window 120h, so as to realize the closure of the battery window 120h by means of the battery holder 710, thereby ensuring the integrity of the structural configuration of the outer contour of the device body.

[0221] In other embodiments, the battery holder 710 can also adopt other structural forms, for example, the battery holder 710 can be configured in a cover plate type structure substantially the same as or matching the structural form of the battery window 120h, and the battery 730 is detachably arranged on the second shell 120 and located in the accommodation cavity 100a. By disassembling the battery holder 710, the battery window 120h can be opened or closed, so as to replace the battery 730.

[0222] In some embodiments, the battery holder 710, the first shell 110 and the second shell 120 are each an integral structure made of a polyimide material. Thus, the battery holder 710 and the shell assembly 100 as components capable of contacting the human skin can have good biocompatibility and stable structural strength; and the materials of the components of the device body are close to each other, which is also conducive to the processing and manufacturing of the related components and the structural cooperation.
