DETAILED DESCRIPTION

[0048] The application will be described in further detail below with 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 addition, features described in the specification and drawings can be combined in any suitable manner in various embodiments.

[0049] In addition, the features described in the specification and drawings can be combined in any suitable manner in various embodiments. Also, the various steps or acts in a method can be rearranged, combined, or divided in any suitable manner without departing from the application. Accordingly, various embodiments of the application are not limited to the order of the steps described in the specification and drawings.

[0050] The serial numbers of components in the specification, such as "first", "second", etc., are used only to distinguish the described objects and do not have any sequential or technical meaning. The application includes "connection" and "coupling" unless otherwise specified.

[0051] The wearable device provided by the embodiments of the application is described mainly by taking an in-ear hearing aid as an example. It should be noted that the in-ear hearing aid is only a specific embodiment of the actual application of the wearable device, and the wearable device can also be other types of hearing aids, earphones, glasses, and the like.

[0052] Referring to FIG. 1, the wearable device includes a shell assembly 100, a core assembly, a speaker device, and other functional components as needed.

[0053] The core assembly can be understood as a collection of related components that implement the main functions of the wearable device, such as supporting the implementation of functions such as sound signal collection, electrical signal conversion processing, device on-off, volume adjustment, power supply, and the like. The core assembly is arranged in the shell assembly 100 to combine with the shell assembly 100 to form a complete functional structure. 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.

[0054] The speaker device can be understood as a collection of components that enable the wearable device to play sound signals. In some embodiments, the speaker device is arranged in connection with the device body, i.e. the speaker device is arranged externally to the housing assembly 100.

[0055] By way of example, referring to Fig. 1, the speaker device is an in-ear speaker, which includes a speaker assembly 810 and a wearing assembly 820. The speaker assembly 810 is arranged in a form that can be adaptively inserted into the ear canal of a user, and mainly serves to play sound signals to the user. The wearing assembly 820 is arranged between the speaker assembly 810 and the housing 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.

[0056] The wearing assembly 820 can be a flexible cable having a signal transmission function, or other wires having both a signal transmission function and a shape memory function. One end of the wearing assembly 820 is fixed and electrically connected to the speaker assembly 810, and the other end of the wearing assembly 820 can be connected to the housing assembly 100 in a detachable or non-detachable manner and electrically connected to the core assembly.

[0057] 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 device body (specifically, the core assembly) can collect external sound signals, and by converting the sound signals into electrical signals and outputting them to the speaker assembly 810, the corresponding sound signals can be played by the speaker assembly 810 to realize the hearing aid function of the wearable device.

[0058] In other embodiments, the speaker device can also be arranged in other forms in the wearable device, for example, the core assembly is arranged directly inside or outside the housing assembly 100 to form a wearable device with different structures or different functions. That is, by selecting and configuring the speaker device, the device body, and the structural relationship therebetween, other structural forms of hearing aids or earphones, glasses, and other types of wearable devices can also be constructed.

[0059] It can be understood that, in the wearable device in the powered state, through the cooperation of the movement assembly and the speaker device, the conversion between the sound signal (for example, the mechanical vibration signal) and the electrical signal can be realized, so that the user can hear the sound through the ear. Generally speaking, the mechanical vibration can act on the eardrum of the user through air as a medium based on the principle of air conduction, and then act on the auditory nerve; 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 principle of bone conduction; for the sound heard by the user, the former can be called "air conduction sound", and the latter can be simply called "bone conduction sound".

[0060] Based on this, through the selection and configuration of the specific functional structure of the movement assembly and the speaker device, the wearable device can form air conduction sound, bone conduction sound, and simultaneously realize air conduction sound and bone conduction sound.

[0061] In order 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 paper, namely: "first direction", "second direction" and "third direction".

[0062] 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.

[0063] Exemplarily, in the state that the wearable device is normally worn between the back of the ear and the head, with the user as a reference, the first direction can refer to the up-down direction of the user, the second direction can refer to the front-back direction of the user, and the third direction can refer to the left-right direction of the user.

[0064] 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 connected to each other in a cooperative manner 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 movement assembly is arranged in the receiving cavity 100a; wherein at least a part of the movement assembly 100 is connected and arranged on the first shell 110, and at least another part of the movement assembly is connected and arranged on the second shell 120.

[0065] Exemplarily, the core assembly includes a control board assembly 200, a microphone assembly 300, a button 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 components in the core assembly connected with the first shell 110 are defined as the first assembly, and the functional components in the core assembly connected with the second shell 120 are defined as the second assembly. Among them, the first assembly can include the control board assembly 200, the microphone assembly 300, and the button assembly 400; the second assembly can include the first interface assembly 500, the second interface assembly 600, and the battery assembly 700.

[0066] The microphone assembly 300 is electrically connected with the control board assembly 200 and is fixed to the first shell 100; the microphone assembly 300 is mainly used to collect the sound signals outside the device (specifically, outside the shell assembly 100), for example, the mechanical vibration of the related components of the microphone assembly 300 itself caused by the external environmental sound, so that the microphone assembly 300 realizes the collection of the sound signals.

[0067] The control board assembly 200 mainly plays a role of regulation and management in the wearable device, for example, the control board assembly 200 can receive the sound signals collected by the microphone assembly 300, and then convert the sound signals into electrical signals and output to the loudspeaker device (specifically, the loudspeaker assembly 810), so as to play the sound signals to the user by means of the loudspeaker device.

[0068] The button assembly 400 is movably connected to the first shell 100 and is arranged in cooperation with the control board assembly 200; through the cooperation of the button assembly 400 and the control board assembly 200, the input of the preset instruction can be realized; for example, the button assembly 400 can input the instruction of controlling the wearable device to start and shut down, the instruction of adjusting the volume, or other instructions to the control board assembly 200.

[0069] 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 with 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 through the wire assembly. Among them, the first interface assembly 500 mainly plays a role of connecting the loudspeaker device in the device main body, for example, in a plug-in form, the first interface assembly 500 is detachably connected with the wearing assembly 820, 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 the sound signals due to the electrical signals provided by the control board assembly 200.

[0070] The second interface assembly 600 is mainly used for connecting external control devices (such as mobile phones, computers, etc.) to transmit data between the external control devices and the wearable device; for example, the working mode, working parameters, volume size, etc. of the wearable device can be adaptively adjusted according to the user's needs through the external control device. The battery assembly 700 is mainly used for powering the power components in the wearable device to provide support for the normal operation of the wearable device.

[0071] In some embodiments, other functional components can also be added or some functional components can be omitted in the movement core assembly, for example, the first interface assembly 500 can be omitted, and the speaker assembly 810 can be directly connected to the control board assembly 200 through the wearing assembly 820; for example, the second interface assembly 600 is replaced by a wireless communication module, and data transmission is performed between the wearable device and the external control device through the wireless communication module.

[0072] That is, the movement core assembly can include one or more of 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.

[0073] 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.

[0074] That is, 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, 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 main body.

[0075] 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 circuit board (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, so as to flexibly establish an electrical connection relationship between the related functional components.

[0076] Based on this, by taking the first shell 110 and the second shell 120 as the installation carrier of the plurality of functional components inside the device, the movement core assembly can be dispersedly arranged at different parts of the shell assembly 100.

[0077] In one aspect, compared with the related art in which an internal skeleton independent of the shell assembly 100 is used as a mounting carrier of the movement assembly, the present application can achieve full utilization of the shell structure and space, reduce the number of internal components of the device, and thus facilitate miniaturization and lightweight design of the wearable device.

[0078] On the other hand, based on the structure in which the movement assembly is dispersedly arranged, not only can the wearable device be quickly disassembled and assembled, but also through disassembly of the first shell 110 and the second shell 120, the first assembly and the second assembly can be disassembled, maintained, recycled, and reused.

[0079] In one embodiment, referring to FIGS. 4 to 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 a form in which the openings face each other in the second direction, so as to form an accommodation cavity 100a.

[0080] As for the movement assembly, the first assembly (for example, the control board assembly 200, the microphone assembly 300, the key 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 (for example, 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.

[0081] 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 being exposed to the shell assembly 100 and affecting the appearance profile of the device main body, thereby improving the appearance aesthetics and wearability of the device main body.

[0082] Secondly, by accommodating the first assembly and the second assembly in the shell space of the first shell 110 and the second shell 120, a certain protection effect can be achieved, so as to prevent the first assembly or the second assembly from being damaged due to bumping before the shell assembly 100 is assembled.

[0083] Thirdly, by setting the first shell 110 and the second shell 120 as shell structures with a certain volume space inside and with an opening, the first shell 110 and the first assembly, and the second shell 120 and the second assembly can be respectively assembled, and after the wiring of the wire assembly is completed, the assembly of the device main body can be conveniently and quickly completed.

[0084] In some embodiments, the first shell 110 can adopt a shell structure with an opening, and the second shell 120 can adopt a cover structure. The second shell 120 is arranged on the first shell 110 in a manner of covering the opening of the first shell 110 to form the accommodation cavity 100a together with the first shell 110. As for the movement core assembly, the first assembly is arranged on the inner wall of the first shell 110 and accommodated in the shell space of the first shell 110. The second assembly is arranged on the surface 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 a cover structure, and the second shell 120 can adopt a shell structure with an opening.

[0085] In this way, the shell assembly 100 is combined in the form of a shell structure cooperating with a cover 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.

[0086] In one embodiment, referring to FIGS. 4-7, an assembly structure is arranged between the first shell 110 and the second shell 120. The assembly structure is mainly used to assemble and fix the first shell 110 provided with the first assembly and the second shell 120 provided with the second assembly into one, so as to form the complete outer contour structure of the device main body (i.e., the shell assembly 100), thereby enabling the wearable device or the device main body to be moved, carried, worn, operated and used by means of the shell assembly 100.

[0087] The assembly structure can adopt different structures according to the connection form between the first shell 110 and the second shell 120. For example, the assembly structure can be a structure suitable for realizing the connection forms such as gluing and welding between the first shell 110 and the second shell 120. For another example, the assembly structure can also be a structure suitable for realizing the detachable connection forms such as clamping and locking between the first shell 110 and the second shell 120.

[0088] Exemplarily, referring to FIGS. 4-7, the assembly structure includes a second fixing structure and a first positioning structure. The second fixing structure is mainly used to stably fix the first shell 110 and the second shell 120 into one. The first positioning structure is mainly used to position the relative positions between the first shell 110 and the second shell 120 to provide support for quickly and accurately assembling the first shell 110 and the second shell 120, and to enhance the structural combination strength of the first shell 110 and the second shell 120 in cooperation with the second fixing structure.

[0089] The second fixing structure comprises a support arm 131 and a fixing pin 132; wherein the support arm 131 protrudes from the inner wall of the second shell 120, for example, the support arm 131 is in an integrated structure with the second shell 120; the fixing pin 132 cooperates with the support arm 131.

[0090] The first positioning structure comprises a first positioning protrusion 141 and a first positioning slot hole 142; wherein the first positioning protrusion 141 protrudes from the inner wall of the first shell 110, and the first positioning protrusion 141 is in an integrated structure with the first shell 110; the first positioning slot hole 142 is integrally formed in the second shell 120 at a position corresponding to the first positioning protrusion 141.

[0091] 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 hole 142 in advance by virtue of the alignment relationship between the first positioning protrusion 141 and the first positioning slot hole 142, so as to limit 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 accommodation cavity 100a (at this time, the support arm 131 is located in the accommodation cavity 100a).

[0092] Then, the fixing pin 132 is inserted into the interior of the shell assembly 100 from the exterior of the shell assembly 100 through a position of the first shell 110 corresponding to the support arm 131 (for example, a pin hole structure can be provided at the position of the first shell 110 corresponding to the support arm 131), so as to integrally fix the first shell 110 and the support arm 131, thereby finally achieving the detachable assembly and fixing between the first shell 110 and the second shell 120.

[0093] In some embodiments, the support arm 131 and the fixing pin 132, the first positioning protrusion 141 and the first positioning slot hole 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.

[0094] By virtue of the cooperation between the second fixing structure and the first positioning structure, the assembly and fixing of the first shell 110 and the second shell 120 can be conveniently, quickly and accurately achieved, so as to effectively enhance the structural stability of the shell assembly 100 (or the device shell), and also provide structural support for the detachable assembly of the device main body or the shell assembly 100.

[0095] For example, during the assembly of the device main body or the shell assembly 100, the first positioning protrusion 141 can be first inserted into the corresponding first positioning slot 142, and then the fixed pin 132 is inserted into the shell assembly 100 by using the cooperation of the support arm 131 and the fixed 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 accuracy of the combined assembly of the first shell 110 and the second shell 120 can be ensured.

[0096] For example, when the device main body needs to be disassembled for maintenance, the fixed pin 132 can be pulled out to disassemble the shell assembly 100, so as to check and maintain the structure and related components inside the device main body.

[0097] In some embodiments, the second fixed structure and the first positioning structure can also adopt other structural forms.

[0098] For example, a plurality of buckle structures are arranged on the first shell 110 and the second shell 120 to replace the second fixed structure and the first positioning structure, so as to assemble and fix the first shell 110 and the second shell 120.

[0099] For another example, a protruding shaft structure is arranged on the inner wall of the first shell 110 corresponding to the position of the support arm 131, and a pin hole structure is arranged on the support arm 131 for the protruding shaft structure to be inserted, so as to form the second fixed structure by the cooperation of the protruding shaft structure and the pin hole structure, thereby positioning and fixing the first shell 110 and the second shell 120 from different positions and different directions under the cooperation of the first positioning structure.

[0100] In some embodiments, the second fixed structure can also be omitted, and one or more first positioning structures are arranged to pre-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 gluing, welding or the like.

[0101] Of course, the first positioning structure can also be omitted, and a plurality of groups of support arms 131 and fixed pins 132 are arranged to fixedly connect the first shell 110 and the second shell 120 from a plurality of different positions. All these will not be repeated here.

[0102] In one embodiment, referring to FIG. 4 and FIG. 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 second fixing structure and the first positioning structure are arranged at 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; wherein, 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 second 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.

[0103] By arranging the second fixing structure and the first positioning structure at the two opposite ends of the shell assembly 100, in the assembly process, the first shell 110 and the second shell 120 can be positioned and combined by means of the first positioning structure in advance, and then the first shell 110 and the second shell 120 can be fixed by using the cooperation relationship between 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, and improve 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.

[0104] In some embodiments, the control board assembly 200, the microphone assembly 300, the key assembly 400, etc. are connected to the inner wall of the first shell 110, the first interface assembly 500, the second interface assembly 600, the battery assembly 700, etc. are connected to 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 to protrude from the inner wall of the second shell 120 substantially along the second direction to the side where the first shell 110 is located; and the fixing pin 132 is arranged to pass through the first shell 110 and the support arm 131 substantially along the third direction; correspondingly, the first positioning protrusion 141 is arranged to protrude from the inner wall or the open end face of the second shell 120 substantially along the second direction to the side where the second shell 120 is located.

[0105] Therefore, based on the differential arrangement of the arrangement directions of the support arm 131 and the first positioning protrusion 141, the combination of the second shell 120 and the second assembly can be regarded as a mounting main body, guiding the assembly personnel to quickly and accurately assemble the combination structure of the first shell 110 and the first assembly to the mounting main body.

[0106] In one embodiment, referring to FIGS. 2-5, the first shell 110 and the second shell 120 are both in a shell structure, and the core assembly includes a control board assembly 200, a microphone assembly 300, a button assembly 400, a first interface assembly 500, a second interface assembly 600, and a battery assembly 700.

[0107] For the sake of distinction and description, the two shell walls of the first shell 110 opposite to each other in the first direction are defined as a first shell wall 110a and a second shell wall 110b, the two shell walls opposite to each other in the third direction are defined as a third shell wall 110c and a fourth 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 a fifth shell wall 110e. The two shell walls of the second shell 120 opposite to each other in the first direction are defined as a sixth shell wall 120a and a seventh shell wall 120b, the two shell walls opposite to each other in the third direction are defined as an eighth shell wall 120c and a 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 a tenth shell wall 120e.

[0108] Among them, 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 opposite to each other in the second direction of the shell assembly 100, 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 are connected to form a receiving cavity 100a.

[0109] Referring to FIGS. 2 and 3, the control board assembly 200 is arranged inside the shell assembly 100, for example, fixedly connected to the third side wall (i.e., the fifth shell wall 110e); the microphone assembly 300 can be a collection of related 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.

[0110] Exemplarily, a sound pickup hole 110f can be provided through the third side wall (i.e., the fifth shell wall 110e) corresponding to the position of the microphone assembly 300, the sound pickup hole 110f is arranged in communication with the microphone assembly 300, and external sound signals are conducted to the microphone assembly 300 through air as a medium to cause the microphone assembly 300 to collect sound signals by generating mechanical vibration.

[0111] Exemplarily, a sound guide pipe can also be provided in the accommodation 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 sound signals.

[0112] Please refer to FIGS. 2 and 3, the key assembly 400 is arranged in the form of movable connection (such as rotary connection, sliding connection, etc.) on the inner wall of the first shell 110 in the accommodation cavity 100a, and the key assembly 400 is at least partially exposed to the third side wall.

[0113] For example, the key assembly 400 is arranged on the side of the control board assembly 200 facing the third side wall in the second direction, a 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 arranged protruding from the third side wall through the key window 110g.

[0114] 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 caused to press the key switch on the control board assembly 200 to input a preset instruction. Of course, 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.

[0115] Please refer to FIGS. 2 and 6, the first interface assembly 500 is fixedly connected (such as fixed to the fourth side wall) with the second shell 120 and arranged in the accommodation cavity 100a in the form of at least partially exposed to the first side wall; Exemplarily, a first connection port 120f can be provided through the first side wall, the interface end of the first interface assembly 500 can be arranged in direct communication with the first connection port 120f, the interface end of the first interface assembly 500 can also extend into the first connection port 120f, and the first interface assembly 500 can also extend out of the shell assembly 100 from the first connection port 120f.

[0116] Correspondingly, an interface structure capable of pluggable and insertable adaptive connection with the first interface assembly 500 can be provided on the loudspeaker device (specifically, the end of the wearing assembly 820 away from the loudspeaker assembly 810), and the interface structure and the first interface assembly 500 are used to fix the loudspeaker device with the device main body and realize the electrical connection between the loudspeaker device and the movement core assembly (such as the control board assembly 200).

[0117] Referring to FIG. 2 and FIG. 6, 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 from the fifth side wall. For example, the 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 communication with the second connecting port 120g and can also extend into the second connecting port 120g. In the wearable device application stage, the external control device such as a mobile phone or a computer can be connected by using the second interface assembly 600, so as to adaptively adjust the working mode and working parameters of the wearable device according to the user's own needs.

[0118] Referring to FIG. 2 to FIG. 4 and FIG. 6, the battery assembly 700 can be fixedly connected with the second housing 120 or movably connected with the second housing 120. For example, the 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 can be 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.

[0119] Therefore, by dispersing the parts of the movement assembly at different positions or different orientations of the housing assembly 100, not only the structure and space of the housing assembly 100 can be more reasonably utilized to ensure the performance of the device, but also the wearable device can be easily operated.

[0120] For example, by arranging the first interface assembly 500 and the battery assembly 700 at opposite ends of the device body along the first direction, and arranging the key assembly 400 between the first interface assembly 500 and the battery assembly 700 along the first direction, on the one hand, it is not only convenient to connect the speaker device (for example, the wearing assembly 820) through the first interface assembly 500, but 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 the middle or lower position of the rear side of the device body, so that the key assembly 400 can be conveniently operated, and the first interface assembly 500 and the battery assembly 700 can avoid interfering with the key assembly 400.

[0121] For example, by setting the third side wall as an arc surface structure, and arranging the two microphone assemblies 300 on the opposite sides of the key assembly 400 or the control panel assembly 200 in the first direction, the sound pickup holes 110f corresponding to the two microphone assemblies 300 can be directed to 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 can be ensured.

[0122] In some embodiments, when the wearable device is in a normal wearing state, for example, the device body is hung on the back side 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:

[0123] The first side wall is the side wall facing the front side of the user in the first direction, the second side wall is the side wall facing the lower side of the user's ear in the first direction, the third side wall is the side wall facing away from the region where the user's head and the back side of the ear meet in the second direction, the fourth side wall is the side wall facing or contacting the region where the user's head and the back side of the ear meet in the second direction, the fifth side wall is the side wall facing or contacting the back side of the user's ear in the third direction, and the sixth side wall is the side wall facing or contacting the user's head in the third direction.

[0124] As shown in FIGS. 1-3 and 5, the size of the shell assembly 100 in the first direction is 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 are set as arc surfaces that can adapt to the physiological structure of the region where the back side of the ear meets the head. In terms of the geometric center line of the shell assembly 100 in the first direction, the geometric center line is set as an arc segment.

[0125] In this way, based on the size difference of the shell assembly 100 in different directions and the structure of the side walls, the outer contour of the shell assembly 100 or the device body is constructed as a profile structure, so that the shell assembly 100 or the device body can adapt to the physiological structure between the back side of the ear and the head, and thus be worn in the form of being clamped or hung on the ear.

[0126] In the embodiment in which the shell assembly 100 adopts a profile structure, the size of the shell assembly 100 in the third direction can be set to gradually decrease 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 (i.e., the end where the first interface assembly 500 is located) can be smaller than the width of the end where the battery assembly 500 is located, so that the space requirement of the battery assembly 500 for the shell assembly 100 can be met.

[0127] 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 connected to each other to form the shell assembly 100.

[0128] Compared with the related art, the body shell of the wearable device is usually made of polycarbonate (PC) material, ABS plastic (i.e., a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S)) and the like. In the present embodiment, based on the good biocompatibility, mechanical strength and other characteristics of the polyimide material, the structure and appearance of the shell assembly 100 can be more stable, and the thickness of the shell wall can be thinner, which is conducive to the miniaturization and light weight of the wearable device, and enhances the stability of the overall structure of the shell assembly 100.

[0129] In one embodiment, referring to FIGS. 2-5 and 7-10, the shell assembly 100 includes the first shell 110, and the movement core assembly includes the key assembly 400 and the control board assembly 200.

[0130] The first shell 110 has an open shell structure, and the shell wall of the first shell 110 is provided with a key window 110g that communicates the shell space (or the accommodation cavity 100a) of the first shell 110 with the outside of the first shell 110. For example, the key window 110g is arranged through the fifth shell wall 110e of the first shell 110.

[0131] The key assembly 400 includes an operation key 410, which is arranged in the shell space of the first shell 110 and movably connected to the inner wall of the first shell 110. At the same time, at least part of the operation key 410 is exposed and protrudes from the first shell 110 through the key window 110g. It can also be understood that the operation key 410 covers the key window 110g and at least part of the operation key 410 is arranged through the key window 110g out of the first shell 110.

[0132] 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 provided with a key switch for cooperating with the operation key 410. By moving the operation key 410 relative to the first shell 110, the operation key 410 can be used to press the key switch of the control board assembly 200, and the input of the preset instruction can be realized.

[0133] By movably connecting the key assembly 400 with the inner wall of the first shell 110, the first shell 110 can be directly used as a mounting carrier of the key assembly 400 without other connecting components, which is beneficial to fully utilize the structure and space of the shell assembly 100, effectively reduces the number of components (for example, internal skeleton) in the wearable device, and provides support for conveniently and quickly disassembling and maintaining the key assembly 400 and realizing lightweight and miniaturized design of the wearable device.

[0134] In one embodiment, referring to FIG. 10, a rotating shaft structure is arranged between the operation key 410 and the first shell 110, and the rotating shaft structure is arranged between the operation key 410 and the third shell wall 110c and between the operation key 410 and the fourth shell wall 110d along a third direction. It can be understood that the axial direction of the rotating shaft structure or the direction of the rotating axis of the rotating shaft structure is the third direction. The first end and the second end of the operation key 410 are opposite to each other in the radial direction (for example, the first direction) of the rotating shaft structure. 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.

[0135] Therefore, based on the presence of the rotating shaft structure, when the operation key 410 is subjected to an external force and rotates relative to the first shell 110 around the rotating shaft structure, one of the first end and the second end of the operation key 410 protrudes from or is raised relative to the first shell 110, and the other end rotates towards the side of the control board assembly 200 to press and trigger the corresponding key switch, thereby realizing input of instruction information.

[0136] For example, referring to FIG. 10, the control board assembly 200 includes a second circuit board 210, a first switch 220, and a second switch 230. The second circuit board 210 is arranged on the side of the operation key 410 opposite to the key window 110g, and the first switch 220 and the second switch 230 are arranged on the side of the second circuit board 210 facing the operation key 410. 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.

[0137] By pressing the first end of the operation key 410 towards the side where the second circuit board 210 is located, the first end of the operation key 410 can press the corresponding first switch 220, thereby realizing input of a preset instruction. In this process, since the operation key 410 rotates relative to the first shell 110 around the rotating shaft structure along the first preset direction (for example, counterclockwise direction), the second end of the operation key 410 can protrude from the outer surface of the first shell 110 or be raised relative to the first end of the operation key 410.

[0138] Conversely, pressing the second end of the operation button 410 on the side where the second circuit board 210 is located can trigger the second switch 220 to achieve the input of a preset instruction; in this process, since the operation button 410 is rotated relative to the first shell 110 in the second preset direction (for example, the clockwise direction) around the rotation shaft structure, the first end of the operation button 410 will protrude from the outer surface of the first shell 110 or be raised relative to the second end of the operation button 410.

[0139] In some embodiments, the first end and the second end of the operation button 410 can be symmetrically arranged about the rotation shaft structure, so as to ensure the smoothness of the rotation of the operation button 410 relative to the first shell 110, and facilitate the identification of the positions of the button switches on the control board assembly 200.

[0140] In one embodiment, referring to FIG. 10, the number of rotation shaft structures is two, and each rotation shaft structure includes a rotation shaft protrusion 181 and a rotation shaft slot hole 420 that cooperate with each other; the rotation shaft slot hole 420 is arranged on the outer surface of the operation button 410, for example, on the two opposite surfaces of the operation button 410 in the third direction; the rotation shaft protrusion 181 is in an integral structure with the first shell 110, for example, protrudes from the third shell wall 110c or the fourth shell wall 110d at a position corresponding to the rotation shaft slot hole 420. It can also be understood that, in the axial direction of the rotation shaft structure, the two rotation shaft structures are arranged on opposite sides of the operation button 410.

[0141] Of course, according to actual needs, the rotation shaft protrusion 181 can also protrude from the surface of the operation button 410, and the rotation shaft slot hole 420 can be arranged on the inner wall surface of the first shell 110.

[0142] By inserting the rotation shaft protrusion 181 into the corresponding rotation shaft slot hole 420, the operation button 410 can be connected to the first shell 110, and the operation button 410 can be provided with the condition of rotating relative to the first shell 110.

[0143] In other embodiments, the rotation shaft structure can also adopt other suitable structures, for example, the rotation shaft structure includes a shaft rod, and a shaft hole structure is throughly arranged at positions corresponding to each other of the first shell 110 and the operation button 410, and by inserting the shaft rod into the shaft hole structure, a relative-rotatable structural connection relationship between the first shell 110 and the operation button 410 can be established.

[0144] In one embodiment, referring to FIG. 10, the operation button 410 is provided with a first limiting structure, which is mainly used to abut against the first shell 110 when the operation button 410 is rotated to a preset limit angle position, so as to limit the rotation angle of the operation button 410.

[0145] Exemplarily, the first limiting structure comprises a third limiting flange 430 which is arranged in an integral structure protruding from the surface of the operation key 410; for example, the third limiting flange 430 is arranged in an integral structure protruding from the surface of the operation key 410 on the opposite sides in the axial direction (or the third direction) of the rotating shaft structure; for another example, the third limiting flange 430 is arranged in an integral structure protruding from the surface of the operation key 410 on the opposite sides in the radial direction (or the first direction) of the rotating shaft structure.

[0146] When the operation key 410 is rotated to a certain angular position in the first preset direction or the second preset direction, the third limiting flange 430 can abut against the inner wall surface (for example, the inner surface of the fifth shell wall 110e) of the first shell 110 at the edge of the key window 110g, thereby preventing the operation key 410 from continuing to rotate.

[0147] Therefore, by limiting the rotation angle of the operation key 410 by the third limiting flange 430, on the one hand, by selecting and setting the rotation angle of the operation key 410, it can be ensured that the first end or the second end of the operation key 410 can completely trigger the corresponding key switch when the operation key 410 is rotated to the limit angular position; on the other hand, it can avoid that the first end or the second end of the operation key 410 protrudes from the first shell 110 to cause the key window 110g to be partially opened, thereby affecting the structural compactness and the outline integrity of the whole device due to the internal space of the shell assembly 100 being communicated with the outside.

[0148] In one embodiment, referring to FIG. 10, the third limiting flange 430 is arranged in an integral structure protruding from the surface of the operation key 410 on the opposite sides in the axial direction of the rotating shaft structure; in the radial direction (for example, in the second direction) of the rotating shaft structure, the third limiting flange 430 is located on the side of the rotating shaft structure away from the key window 110g; and the third limiting flange 430 extends from the position close to the rotating shaft structure to the side where the first end and the second end of the operation key 410 are located.

[0149] Therefore, the third limiting flange 430 can adapt to the rotation track of the operation key 410, thereby achieving the effect of limiting the rotation angle of the operation key 410.

[0150] In some embodiments, the operation key 410 and the shell assembly 100 are both made of polyimide material, for example, the operation key 410, the first shell 110 and the second shell 120 are all made of an integral structure of polyimide material; in this way, the related components in the wearable device which are in contact with the human body can have good biocompatibility and stable structural strength.

[0151] Referring to FIG. 1, FIG. 2 and FIG. 8, the key window 110g is disposed through the fifth shell wall 110e of the first shell 110, and the fifth shell wall 110e or the outer wall of the fifth shell wall 110e is an arc surface structure protruding outward in the second direction; wherein the first end and the second end of the operation key 410 are two ends of the operation key 410 opposite in the first direction; in terms of the control board assembly 200, the plane in which the control board assembly 200 is located is perpendicular to the third shell wall 110c and the fourth shell wall 110d, that is, the plane in which the control board assembly 200 (specifically the second circuit board 210) is located is parallel to the rotation axis or the axis of the rotation shaft structure of the operation key 410.

[0152] In this way, based on the arc surface structure feature of the first shell 110, structural support can be provided for the first end and the second end of the operation key 410 protruding from the first shell 110, which is conducive to the user accurately and quickly identifying the position of the operation key 410 on the first shell 110, thereby facilitating the pressing operation of the operation key 410.

[0153] Considering that the fifth shell wall 110e adopts an arc surface structure, and the plane in which the control board assembly 200 (specifically the second circuit board 210) is located is usually parallel to the rotation axis or the axis of the rotation shaft structure of the operation key 410; this can make it difficult to keep the height of the first end and the second end of the operation key 410 protruding from the first shell 110 (i.e. the outer wall surface of the fifth shell wall 110e) consistent, which can easily reduce the operation experience of the key assembly 400 and cause misoperation and other problems.

[0154] In some embodiments, referring to FIG. 8 and FIG. 10, in the wearing state of the wearable device, the first end of the operation key 410 can be understood as the end of the operation key 410 in the first direction or the user's up-down direction that is relatively low in position; the outer surface of the first end of the operation key 410 is provided with a key protrusion 440 protruding outward from the first shell 110, for example, the key protrusion 440 is disposed outward from the outer surface of the first end of the operation key 410 in the second direction.

[0155] In this way, with the help of the key protrusion 440, not only can the height difference of the two ends of the operation key 410 relative to the outer surface of the first shell 110 (i.e. the outer wall surface of the fifth shell wall 110e) be adjusted or compensated, but also the operation experience can be improved, and the risk of misoperation of the operation key 410 can be reduced.

[0156] In other embodiments, the key protrusion 440 can also be disposed outward from the second end of the operation key 410, or the first end and the second end of the operation key 410 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.

[0157] In one embodiment, referring to FIGS. 7 and 9, the inner surface of the first housing 110 (specifically, the fifth housing wall 110e) is provided with a first fixing structure, which is mainly used to support and fix the second circuit board 210 at a preset position in the housing space of the first housing 110, so as to limit and fix the control board assembly 200 on the side of the key assembly 400 away from the key window 110 in the third direction.

[0158] Exemplarily, referring to FIGS. 7 and 9, the first fixing structure includes a plurality of support columns 161 protruding from the fifth housing 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, so as to support and fix the second circuit board 210 or the control board assembly 200 in a manner of being spaced apart from the inner surface of the fifth housing wall 110e.

[0159] Therefore, by means of the first fixing structure (specifically, the support column 161), a certain structural gap can be formed between the second circuit board 210 and the inner wall of the first housing 110 (specifically, the inner wall of the fifth housing wall 110e), so as to provide a structural space for assembling the key assembly 400 in the first housing 110. For example, the second circuit board 210 can be arranged transversely in the third direction (or the width direction of the device main body) in the housing space of the first housing 110 (it can also be understood that the plane where the second circuit board 210 is located is substantially perpendicular to the third housing wall 110c and the fourth housing wall 110d), so as to utilize the structural gap between the second circuit board 210 and the fifth housing 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 dimensions of the device main body, and it is also convenient to fix and assemble the key assembly 400 and the control board assembly 200 in the first housing 110 in steps.

[0160] In other embodiments, the first 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 provided on the inner wall surface of the first housing 110 for inserting and fixing the support column 161; which will not be described herein.

[0161] In one embodiment, referring to FIGS. 4-6 and in combination with FIGS. 9 and 10, a second limiting structure is further arranged between the first shell 110 and the second shell 120; on one hand, the second 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 second limiting structure can prevent the first shell 110 and the second shell 120 from structural deformation at the interface therebetween, so as to avoid extrusion of the control board assembly 200 (specifically, the second circuit board 210) due to structural deformation of the shell.

[0162] Exemplarily, referring to FIGS. 4-6, the first shell 110 and the second shell 120 both adopt a shell structure, and the interface of the first shell 110 and the second shell 120 that are in contact with each other in the second direction is defined as an engaging surface; wherein the engaging surface of the first shell 110 is provided with a first limiting flange 171 protruding toward the side of the second shell 120 in the second direction, and the engaging surface of the second shell 120 is provided with a second limiting flange 172 protruding toward the side of the first shell 110 in the second direction.

[0163] In terms of the state of the shell assembly 100 after assembly, 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).

[0164] By means of the second limiting flange 172 abutting against the first limiting flange 171 from the inside of the accommodating cavity 100a, a second 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 extrusion of the control board assembly 200 (specifically, the second circuit board 210), but also enhance the structural connection strength of the first shell 110 and the second shell 120 at the engaging 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.

[0165] In some embodiments, the second limiting structure can also be arranged in other structural forms between the engaging surfaces of the first shell 110 and the second shell 120, for example, a flange is arranged on the engaging surface of the second shell 120, and a slot is arranged on the engaging 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 a second limiting structure, thereby also preventing the first shell 110 from being deformed in the third direction, thereby achieving the purpose of preventing the first shell 110 from extruding the first assembly (for example, the control board assembly 200).

[0166] In some embodiments, the second 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.

[0167] In one embodiment, referring to FIGS. 4-6, the second limiting structure is arranged in multiple groups, and the multiple groups of the second limiting structure are arranged 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. In this way, the first shell 110 can be further prevented from deforming, and the stability of the structural connection between the first shell 110 and the second shell 120 can be improved.

[0168] Of course, the second limiting structure can also be arranged at intervals around 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.

[0169] In one embodiment, referring to FIGS. 4-6, the second limiting structure is further provided with a second avoiding gap 173. During the assembly of the first shell 110 and the second shell 120, the second avoiding gap 173 can avoid part of the first assembly or the second assembly, so as to adapt to the space size requirement of the first assembly or the second assembly to the accommodating cavity 100a.

[0170] 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 second avoiding gap 173 can be a gap structure 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.

[0171] During the assembly of the first shell 110 and the second shell 120, the second avoiding gap 173 can make the second shell 120 adapt to the contour size of the second circuit board 210, 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 components can be prevented from being squeezed or interfered.

[0172] The above describes the present application by using specific examples, which is only used to help understand the present application and does not limit the present application. According to the idea of the present application, a person skilled in the art of the present application can make several simple deductions, deformations or substitutions.
