Similar elements in different embodiments are numbered with associated similar elements.

This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0032] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementation methods. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various orders in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and do not mean that they are necessary orders, unless otherwise specified that a certain order must be followed. The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "connection" mentioned in this application, unless otherwise specified, include direct and indirect connections (connections).

[0033] The present application provides a wearable device, such as Figure 1 The overall outline structure of an in-ear hearing aid is shown. The in-ear hearing aid can be a specific embodiment of the practical application of the wearable device; the wearable device includes a shell component 100, a movement component, a speaker device, and other functional components that exist as needed, which are described in detail below.

[0034] The core component can be understood as a collection of related components that realize the main functions of the wearable device. For example, the core component can support the collection of sound signals, conversion and processing of electrical signals, powering on and off the device, volume adjustment, power supply and other functions; the core component is arranged in the shell component 100, so as to be combined with the shell component 100 to form a complete functional structure; for the convenience of distinction and description, the combined structure of the shell component 100 and the core component is defined as the device body.

[0035] The speaker device can be understood as a collection of related components that realize the function of playing sound signals of the wearable device. In some embodiments, the speaker device is connected to the device body, that is, the speaker device is connected and arranged outside the housing assembly 100. For example, please refer to Figure 1 , the speaker device is an in-ear speaker, which includes a speaker component 810 and a wearing component 820; wherein the speaker component 810 is configured to be adaptably inserted into the user's ear canal, and mainly plays the role of playing sound signals to the user; the wearing component 820 is connected and arranged between the speaker component 810 and the shell component 100 in the form of electrically connecting the speaker component 810 and the movement component, and is mainly used to establish a signal connection relationship between the movement component and the speaker component 810. The wearing component 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 component 820 is fixed and electrically connected to the speaker component 810, and the other end of the wearing component 820 can be connected to the shell component 100 in a detachable or non-detachable manner and electrically connected to the movement component.

[0036] With the help of the wearing component 820, the device body can be stably worn on the user's ear, and the speaker component 810 can be inserted into the user's ear canal; the external sound signal can be collected through the device body (specifically, the movement component), and by converting the sound signal into an electrical signal and outputting it to the speaker component 810, the speaker component 810 can be used to play the corresponding sound signal to realize the hearing aid function of the wearable device.

[0037] In other embodiments, the speaker device can also be configured in other forms on the wearable device. For example, the reference movement component can be directly set inside or outside the shell component 100 to form a wearable device with different structural forms or different functions; that is, by selecting and configuring the speaker device, the device body and the structural relationship between the two, hearing aids or other types of wearable devices such as headphones, glasses, etc. with other structural forms can also be constructed.

[0038] It is understood that when a wearable device is powered on, the cooperation between the core assembly and the speaker assembly can convert sound signals (such as mechanical vibration signals) into electrical signals, allowing the user to hear the sound through their ears. Generally speaking, mechanical vibrations can act on the user's eardrum and, in turn, the auditory nerve based on the principle of air conduction, primarily through air as a medium. Mechanical vibrations can also act directly on the user's auditory nerve based on the principle of bone conduction, through the user's bones and tissue as a medium. The former can be referred to as "air-conducted sound," and the latter can be simply referred to as "bone-conducted sound." Based on this, by selecting and configuring the specific functional structures of the core assembly and the speaker assembly, a wearable device can generate both air-conducted sound and bone-conducted sound, or even achieve both simultaneously.

[0039] The following mainly describes the wearable device as an air conduction hearing aid as an example to describe the device body and its related structures. Other components of the wearable device (such as the speaker device) can refer to the existing technology; however, it should be noted that the wearable device can also be other devices such as headphones and glasses.

[0040] In order to describe the structural construction of the device body more clearly and in detail, based on the outer contour of the device body, this article defines three directions that intersect or are perpendicular to each other, namely: "first direction", "second direction" and "third direction". For example, when the wearable device is in a natural placement state, the first direction may refer to the length direction of the entire device, the second direction may refer to the thickness direction of the entire device, and the third direction may refer to the width direction of the entire device. For example, when the wearable device is normally worn between the back of the ear and the head, with the user as the reference base, the first direction may refer to the up and down direction of the user, the second direction may refer to the front and back direction of the user, and the third direction may refer to the left and right direction of the user.

[0041] For one example, see Figures 1 to 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 are matched and connected to form a accommodating cavity 100a inside the shell assembly 100 (or between the first shell 110 and the second shell 120); the movement assembly is arranged in the accommodating cavity 100a; wherein, at least a part of the movement assembly 100 is connected to the first shell 110, and at least another part of the movement assembly 100 is connected to the second shell 120.

[0042] For example, the core assembly includes a control panel 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 ease of distinction and description, the functional components of the core assembly connected to the first housing 110 are defined as first components, and the functional components of the core assembly connected to the second housing 120 are defined as second components. The first component may include the control panel assembly 200, the microphone assembly 300, and the key assembly 400; the second component may include the first interface assembly 500, the second interface assembly 600, and the battery assembly 700.

[0043] The microphone assembly 300 is electrically connected to the control board assembly 200 and is respectively fixed to the first shell 110; the microphone assembly 300 is mainly used to collect sound signals from the outside of the device (specifically, the outside of the shell assembly 100), for example, due to external environmental sounds, the relevant components of the microphone assembly 300 itself generate mechanical vibrations, thereby enabling the microphone assembly 300 to collect sound signals.

[0044] The control panel assembly 200 mainly plays a role in regulation and management in the wearable device. For example, the control panel assembly 200 can receive the sound signal collected by the microphone assembly 300, and then convert the sound signal into an electrical signal and output it to the speaker device (specifically, the speaker assembly 810), thereby playing the sound signal to the user with the help of the speaker device.

[0045] The button assembly 400 is movably connected to the first shell 110 and is arranged in coordination with the control panel assembly 200; through the coordination between the button assembly 400 and the control panel assembly 200, the input of preset instructions can be realized; for example, instructions for controlling the power on and off of the wearable device, instructions for volume adjustment or other instructions can be input to the control panel assembly 200 through the button assembly 400.

[0046] The first interface assembly 500, the second interface assembly 600, and the battery assembly 700 are connected to the second housing 120 and are electrically connected to the control board assembly 200; for example, an electrical signal connection is established with the control board assembly 200 via a wire assembly. The first interface assembly 500 primarily serves to connect the speaker device within the device body, for example, by being removably connected to the wearable assembly 820 in a pluggable manner, thereby establishing a signal connection between the speaker assembly 810 and the control board assembly 200, so that the speaker assembly 810 can generate or play sound signals in response to the electrical signals provided by the control board assembly 200.

[0047] The second interface assembly 600 is primarily used to connect to an external control device (e.g., a mobile phone, computer, or other external device) to transmit data between the external control device and the wearable device. For example, the external control device can be used to adaptively adjust the wearable device's operating mode, operating parameters, volume, and other settings based on user needs. The battery assembly 700 is primarily used to power the electrical components of the wearable device, supporting its normal operation.

[0048] In some embodiments, other functional components may be added to the core assembly or some functional components may be omitted. For example, the first interface assembly 500 may be omitted, and the speaker assembly 810 may be directly connected to the control panel assembly 200 through the wearable assembly 820. For another example, the second interface assembly 600 may be replaced with a wireless communication module, and data may be transmitted between the wearable device and the external control device via the wireless communication module. In other words, the core assembly may include one or more of the control panel 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.

[0049] In some embodiments, based on the internal structure of the shell assembly 100 , the functional components in the first assembly and the second assembly can also be interchanged with each other. For example, the first interface assembly 500 belongs to the first assembly and is connected to the first shell 110 .

[0050] That is to say, the control panel assembly 200, microphone assembly 300, button assembly 400, first interface assembly 500, second interface assembly 600 and battery assembly 700, etc. can be selectively connected to the first shell 110 or the second shell 120 according to the structural layout and functional configuration of the shell assembly 100 or the device body.

[0051] It should be noted that the description of "wire assembly" is introduced in this article. The wire assembly can be a wire, a cable, a flexible printed circuit board (FPC), etc., to adapt to the internal structure of the shell assembly 100 and the spatial arrangement relationship between the relevant functional components, so as to flexibly establish an electrical connection relationship between the relevant functional components.

[0052] Based on this, with the help of the first shell 110 and the second shell 120 as the installation carriers of multiple functional components inside the device, the core components can be dispersedly set in different parts of the shell assembly 100. On the one hand, compared with the related art, which uses an internal skeleton independent of the shell assembly 100 as the installation carrier of the core components, the present application can make full use of the shell structure and space, reduce the number of components inside the device, and thus facilitate the miniaturization and lightweight design of the wearable device. On the other hand, based on the structural form of the dispersed setting of the core components, not only can the wearable device be quickly disassembled and assembled, but also by disassembling the first shell 110 and the second shell 120, the first component and the second component can be disassembled, maintained, recycled and reused in a targeted manner.

[0053] For one example, see Figures 4 to 7 The first shell 110 and the second shell 120 both adopt a shell structure with an opening. The first shell 110 and the second shell 120 are matched and connected in the second direction with the openings facing each other to enclose and form the accommodating cavity 100a.

[0054] As for the core components, the first component (such as the control panel component 200, the microphone component 300, the button component 400, etc.) is connected to the inner wall of the first shell 110, so that at least part of the first component is accommodated in the shell space of the first shell 110; the second component (such as the first interface component 500, the second interface component 600, the battery component 700, etc.) is connected to the inner wall of the second shell 120, so that at least part of the second component is accommodated in the shell space of the second shell 120.

[0055] First, by connecting the first component to the inner wall of the first shell 110 and the second component to the inner wall of the second shell 120, the connection structure between the movement component and the shell component 100 can be avoided from being exposed in the shell component 100 and affecting the appearance contour of the device body, thereby improving the appearance and wearability of the device body.

[0056] Secondly, using the shell space of the first shell 110 and the second shell 120 to accommodate the first component and the second component can play a certain protective role and prevent the first component or the second component from being damaged due to bumps before the shell component 100 is assembled.

[0057] Third, by setting the first shell 110 and the second shell 120 as a shell-type structure with a certain volume space inside and an opening, it is convenient to assemble the first shell 110 and the first component, and the second shell 120 and the second component respectively. After completing the wiring of the wire component, the assembly of the device body can be completed conveniently and quickly.

[0058] In some embodiments, the first housing 110 may be a housing-type structure with an opening, while the second housing 120 may be a cover-type structure. The second housing 120 is disposed on the first housing 110 to cover the opening of the first housing 110, thereby forming a housing cavity 100a with the first housing 110. Regarding the movement assembly, the first assembly is connected to the inner wall of the first housing 110 and accommodated within the housing space of the first housing 110. The second assembly is connected to a surface of the second housing 120 facing the first housing 110. After the first and second housings 110 are assembled, the second assembly is equivalently accommodated within the housing space of the first housing 110 (i.e., the housing cavity 100a). Of course, the first housing 110 may be a cover-type structure, while the second housing 120 may be a housing-type structure with an opening.

[0059] Therefore, the shell assembly 100 is formed by combining the shell structure with the cover structure, which is not only conducive to the rapid assembly of the device body, but also can form wearable devices with different structural forms or assembly methods, thereby meeting different application requirements.

[0060] For one example, see Figures 4 to 7 An assembly structure is provided between the first shell 110 and the second shell 120. The assembly structure is mainly used to assemble and fix the first shell 110 with the first component installed and the second shell 120 with the second component installed into one body, so as to roughly form a complete outer contour structure of the device body (i.e., the shell assembly 100), so that the wearable device or the device body can be moved, carried, worn, operated and used with the help of the shell assembly 100.

[0061] 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 related structure suitable for realizing a connection form 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 related structure suitable for realizing a detachable connection form such as snapping and locking between the first shell 110 and the second shell 120.

[0062] For example, see Figures 4 to 7 The assembly structure includes a first fixing structure and a first positioning structure; wherein the first fixing structure is mainly used to firmly fix the first shell 110 and the second shell 120 into one; the first positioning structure is mainly used to locate the relative position between the first shell 110 and the second shell 120 to provide support for quick and accurate assembly of the first shell 110 and the second shell 120, and at the same time cooperate with the first fixing structure to enhance the structural combination strength of the first shell 110 and the second shell 120.

[0063] The first fixing structure includes a support arm 131 and a fixing pin 132 ; wherein the support arm 131 is protruding from the inner wall surface of the second shell 120 , for example, the support arm 131 and the second shell 120 are an integrated structure; the fixing pin 132 cooperates with the support arm 131 .

[0064] The first positioning structure includes a first positioning protrusion 141 and a first positioning slot 142; wherein, the first positioning protrusion 141 is protruding from the inner wall surface of the first shell 110, and the first positioning protrusion 141 and the first shell 110 are an integrated structure; the first positioning slot 142 is integrally formed in the position of the second shell 120 corresponding to the first positioning protrusion 141.

[0065] During 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 pre-inserted into the first positioning slot 142 with the help of the alignment relationship between the first positioning protrusion 141 and the first positioning slot 142, thereby limiting the relative position of the first shell 110 and the second shell 120. For example, the open end surface of the first shell 110 and the open end surface of the second shell 120 are against each other, so that the first space and the second space are connected to form the accommodating cavity 100a (at this time, the support arm 131 is located in the accommodating cavity 100a).

[0066] Then, the fixing pin 132 is passed from the outside 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 set at the position of the first shell 110 corresponding to the support arm 131) and into the interior of the shell assembly 100, so that the first shell 110 and the support arm 131 are penetrated and fixed as a whole, so as to finally realize the detachable assembly and fixation between the first shell 110 and the second shell 120.

[0067] 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 swapped; for example, the support arm 131 is protruding from the inner wall of the first shell 110, and the first positioning protrusion 141 is protruding from the inner wall of the second shell 120.

[0068] With the help of the mutual cooperation between 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 conveniently, quickly and accurately achieved, so as to effectively enhance the structural stability of the shell assembly 100 (or device housing), and also provide structural support for the detachable assembly of the device body or the shell assembly 100.

[0069] For example, in the process of assembling the device 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 fixing pin 132 can be inserted by utilizing the matching 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 accuracy of the combined assembly of the first shell 110 and the second shell 120 can be guaranteed.

[0070] For example, when the device body needs to be disassembled for maintenance, the housing assembly 100 can be disassembled by simply pulling out the fixing pin 132 so as to inspect and maintain the internal structure and related components of the device body.

[0071] In some embodiments, the first fixing structure and the first positioning structure may also adopt other structural forms.

[0072] For example, a plurality of mutually cooperating snap structures are provided on the first shell 110 and the second shell 120 , and the snap structures are used to replace the first fixing structure and the first positioning structure to achieve assembly and fixation of the first shell 110 and the second shell 120 .

[0073] For another example, a convex shaft structure is set on the inner wall of the first shell 110 at a position corresponding to the support arm 131, and a pin hole structure for the convex shaft structure to be inserted is set on the support arm 131. The first fixing structure is formed by the cooperation of the convex shaft structure and the pin hole structure, so that with the cooperation of the first positioning structure, the first shell 110 and the second shell 120 can be positioned and fixed from different positions and different orientations.

[0074] In some embodiments, the first fixing structure may be omitted, and the first shell 110 and the second shell 120 may be pre-positioned by providing one or more first positioning structures, and then the first shell 110 and the second shell 120 may be finally fixed by gluing, welding, etc.

[0075] Of course, the first positioning structure can also be omitted, and multiple groups of support arms 131 and fixing pins 132 can be provided to fix the first housing 110 and the second housing 120 at multiple different positions.

[0076] For one example, see Figure 4 and Figure 5The first shell 110 and the second shell 120 are opposite to each other in the second direction and are matched to form a 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; wherein, when the wearable device is in a normal wearing state, 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.

[0077] By placing the first fixing structure and the first positioning structure at opposite ends of the shell assembly 100, during the assembly process, the first shell 110 and the second shell 120 can be positioned and spliced ​​in advance with the help of the first positioning structure, and then the first shell 110 and the second shell 120 can be fixed by utilizing the matching relationship between the fixing pin 132 and the support arm 131; this is conducive to the assembler 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 body; at the same time, it is also convenient to inspect and maintain its internal structure and related functional components by disassembling the shell assembly 100.

[0078] In some embodiments, the control panel assembly 200, the microphone assembly 300, etc. are connected to the inner wall of the first shell 110, the first interface assembly 500, 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-type structure; the support arm 131 is arranged roughly along the second direction toward the side where the first shell 110 is located, protruding from the inner wall of the second shell 120; the fixing pin 132 is arranged roughly along the third direction through the first shell 110 and the support arm 131; accordingly, the first positioning protrusion 141 is arranged roughly along the second direction toward the side where the second shell 120 is located, protruding from the inner wall or open end face of the second shell 120.

[0079] Therefore, based on the differentiated arrangement direction of the support arm 131 and the first positioning protrusion 141, the combination of the second shell 120 and the second component can be regarded as an installation body, guiding the assembler to quickly and accurately assemble the combined structure of the first shell 110 and the first component to the installation body.

[0080] The following mainly takes the first shell 110 and the second shell 120 both adopting a shell-type structure as an example to illustrate the device body and its related structures.

[0081] For the convenience of distinction 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 connected between 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.

[0082] The two shell walls of the second shell 120 that are 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 that are 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 connected between 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.

[0083] The first shell wall 110a and the sixth shell wall 120a are combined to form the first side wall of the housing assembly 100, the second shell wall 110b and the seventh shell wall 120b are combined to form the second side wall of the housing assembly 100, the fifth shell wall 110e and the tenth shell wall 120e can be understood as the third and fourth side walls of the housing assembly 100 that are opposite to each other in the second direction, the third shell wall 110c and the eighth shell wall 120c are combined to form the fifth side wall of the housing assembly 100, and the fourth shell wall 110d and the ninth shell wall 120d are combined to form the sixth side wall of the housing assembly 100. It can be understood that the first, second, third, fourth, fifth, and sixth side walls of the housing assembly 100 are connected to form the accommodating cavity 100a.

[0084] For some examples, see Figures 1 to 3 and Figure 5 The outer contour structure of the shell component 100 or the device body adopts a contoured structure so that the shell component 100 or the device body can adapt to the physiological structure between the back of the ear and the head, so that it can be worn on the ear in the form of being clamped or hanging on the ear.

[0085] That is to say, when the wearable device is in a normal wearing state, for example, the device body is hung on the back of the user's ear by relying on the wearing component 820, and the speaker component 810 is inserted into the user's ear canal: 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 area where the user's head and the back of the ear are connected in the second direction, the fourth side wall is the side wall facing or contacting the area where the user's head and the back of the ear are connected in the second direction, the fifth side wall is the side wall facing or contacting the back 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.

[0086] The size of the housing assembly 100 in the first direction can generally be set to be larger than the size of the housing assembly 100 in the second and third directions; the third side wall and the fourth side wall can generally be set to a curved surface structure that can adapt to the physiological structure of the area where the back of the ear and the head meet, for example, Figure 2 and Figure 8 The third sidewall is a curved surface structure that bulges toward the exterior of the housing assembly 100 in the second direction, and has a predetermined length in the first direction. Regarding the geometric centerline of the housing assembly 100 in the first direction, the geometric centerline can generally be configured as an arc segment.

[0087] In some embodiments, the core assembly includes a control panel 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. The layout of the core assembly on the shell assembly 100 is described below.

[0088] See also Figure 2 The control panel 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 that can form "air-conducted sound", and the microphone assembly 300 is fixedly arranged on the third side wall and maintains air communication with the outside of the shell assembly 100 at the third side wall.

[0089] For example, a sound pickup hole 110f can be provided through the third side wall (i.e., the fifth shell wall 110e) at a position corresponding to the microphone assembly 300. The sound pickup hole 110f is arranged in communication with the microphone assembly 300, and the external sound signal is transmitted to the microphone assembly 300 using air as a medium, so as to enable the microphone assembly 300 to collect the sound signal by generating mechanical vibration.

[0090] For example, a sound-conducting pipe may be provided in the accommodating cavity 100 a , and the microphone assembly 300 is connected to the outside of the housing assembly 100 through the sound-conducting pipe, thereby collecting sound signals.

[0091] For some examples, see Figure 2 The number of microphone assemblies 300 is set to two, and the two microphone assemblies 300 are arranged on opposite sides of the control board assembly 200 in the first direction; as far as the device body is concerned, the two microphone assemblies 300 can collect sound signals from different directions.

[0092] See also Figure 2 and Figure 3 The button assembly 400 is arranged in the accommodating cavity 100a in the form of a movable connection (such as a rotating connection, a sliding connection, etc.) on the inner wall of the first shell 110, and the button assembly 400 is at least partially exposed on the third side wall.

[0093] For example, the button assembly 400 is arranged on one side of the control panel assembly 200 facing the third side wall in the second direction, and a button window 110g is set through the position of the third side wall corresponding to the button assembly 400. The button assembly 400 is exposed through the button window 110g and protrudes from the third side wall.

[0094] By applying a pressing force to the button assembly 400 toward one side of the control board assembly 200 , the button assembly 400 can be urged to press the button switch on the control board assembly 200 to implement input of a preset instruction.

[0095] In some embodiments, the button assembly 400 may also include a switch component capable of generating an electrical signal. The button assembly 400 is electrically connected to the control board assembly 200 , and command information is input to the control board assembly 200 by triggering the button assembly 400 .

[0096] See also Figure 2 、 Figure 6 and Figure 12 The first interface component 500 is fixedly connected to the second shell 120 (for example, fixed to the fourth side wall) in a form that is at least partially exposed on the first side wall and arranged in the accommodating cavity 100a; illustratively, a first connection port 120f can be set through the first side wall, and the interface end of the first interface component 500 can be arranged to be opposite to the first connection port 120f in the first direction. The interface end of the first interface component 500 can also extend into the first connection port 120f, and can also extend out of the shell component 100 from the first connection port 120f.

[0097] Correspondingly, an interface structure that can be pluggably connected to the first interface component 500 can be provided on the speaker device (specifically, the end of the wearable component 820 away from the speaker component 810). The interface structure and the first interface component 500 can be used to fix the speaker device to the device body, and realize the electrical connection between the speaker device and the core component (such as the control panel component 200).

[0098] See also Figure 2 、 Figure 6 and Figure 12 The second interface assembly 600 is fixedly connected to the second shell 120 (for example, fixed to the fourth side wall) and arranged in the accommodating cavity 100a in a form that is at least partially exposed on the fifth side wall or the sixth side wall. For example, a second connection port 120g can be provided through the fifth side wall (for example, the eighth shell wall 120c). The interface end of the second interface assembly 600 can be arranged to be opposite and communicate with the second connection port 120g in the third direction, and the interface end of the second interface assembly 600 can also extend into the second connection port 120g. During the application stage of the wearable device, the second interface assembly 600 can be used to connect to external control devices such as mobile phones and computers to adaptively adjust the operating mode and operating parameters of the wearable device according to the user's own needs.

[0099] See also Figure 2 and Figure 4 The battery assembly 700 can be fixedly connected to the second shell 120 or movably connected to the second shell 120; for example, a battery window 120h can be set in the area where the second side wall and the fourth side wall meet, and the battery assembly 700 is rotatably connected to the second shell 120, so that by rotating the battery assembly 700, the battery assembly 700 can enter and exit the accommodating cavity 100a through the battery window 120h to replace the battery.

[0100] Based on this, by distributing the various parts of the movement assembly in different positions or orientations of the shell assembly 100, not only can the structure and space of the shell assembly 100 be more reasonably utilized to ensure the performance of the device, but it also facilitates the operation of the wearable device.

[0101] For example, by arranging the first interface component 500 and the battery component 700 at opposite ends of the device body along the first direction, the button component 400 is arranged at a position between the first interface component 500 and the battery component 700 along the first direction; on the one hand, it is not only convenient to connect the speaker device (such as the wearable component 820) through the first interface component 500, but also convenient to replace the battery in the battery component 700; on the other hand, when the device is in the wearable state, the button component 400 can be roughly located in the middle of the rear side or the lower rear side of the device body, which not only makes it convenient to operate the button component 400, but also avoids the first interface component 500 and the battery component 700 from causing structural interference with the button component 400.

[0102] For another example, by arranging two microphone assemblies 300 on opposite sides of the button assembly 400 or the control panel assembly 200 in the first direction, the curved surface structure adopted by the third side wall can be utilized so that the sound pickup channels 110f corresponding to the two microphone assemblies 300 face different directions, thereby effectively preventing external sound signals from being blocked by parts of the user's body, thereby ensuring the effect of the microphone assembly 300 on sound signal collection.

[0103] In embodiments where the housing assembly 100 employs a contoured structure, the dimensions of the housing assembly 100 in the third direction can be configured to gradually decrease from the second sidewall toward the first sidewall. That is, the dimensions of the first end of the housing assembly 100 in the third direction are smaller than those of the second end. This allows the width of the end of the device body in the first direction for connecting to the speaker (i.e., where the first interface assembly 500 is located) to be smaller than the width of the end where the battery assembly 500 is located, thus accommodating the spatial requirements of the housing assembly 100 as required by the battery assembly 500.

[0104] In some embodiments, the housing assembly 100 is made of polyimide (PI) material. For example, the first housing 110 and the second housing 120 are both made of an integrated structure of polyimide material, and the two are connected relative to each other to form the housing assembly 100 .

[0105] Compared with the related art, the body shell of the wearable device adopts materials such as polycarbonate (PC for short) material, ABS plastic (i.e., a terpolymer of three monomers: acrylonitrile (A), butadiene (B), and styrene (S)); in this embodiment, based on the good biocompatibility and high mechanical strength of the polyimide material, the structural form (including the appearance) of the shell assembly 100 can be made more stable, and the thickness of the shell is thinner, which is conducive to the miniaturization and lightweight of the wearable device and enhances the stability of the overall structure of the shell assembly 100.

[0106] For one example, see Figures 8 to 10 The core assembly includes a microphone assembly 300. The first housing 110 is provided with a sound pickup channel 110f, which extends through the fifth housing wall 110e to connect the accommodating cavity 100a with the exterior of the housing assembly 100. The microphone assembly 300 can be understood as a collection of related components capable of "air-conducted sound." The microphone assembly 300 is disposed within the accommodating cavity 100a and fixed to the inner wall of the first housing 110 (e.g., the fifth housing wall 110e). The sound input channel of the microphone assembly 300 is sealed and connected to the sound pickup channel 110f.

[0107] For example, see Figure 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 shell wall 110e in a manner that covers the sound outlet end of the sound pickup channel 110f. For example, the protective net 330 is glued to the fifth shell wall 110e. The first circuit board 310 is superimposed and fixed to the side of the protective net 330 facing away from the sound pickup channel 110f (for example, the first circuit board 310 and the protective net 330 are glued together). The microphone 320 is arranged on the side of the first circuit board 310 facing away from the protective net 330. The first circuit board 310 is provided with a sound guide channel 310a at a position corresponding to the sound input channel of the microphone 320.

[0108] Among them, the microphone 320 is the main component in the microphone assembly 300 for collecting sound signals, and the first circuit board 310 is the installation carrier of the microphone 320. An electrical signal connection relationship is established between the microphone 320 and the control board assembly 200 through the first circuit board 310.

[0109] Based on this, using the first housing 110 as a mounting carrier for the microphone assembly 300 can not only fully utilize the structural space of the housing assembly 100, but also reduce the number of related components, thereby supporting lightweight and miniaturized wearable devices. Furthermore, due to the sealed connection between the microphone assembly 300 and the sound pickup channel 110f, external sound signals can enter the sound input channel of the microphone assembly 300 through the sound pickup channel 110f using air as a medium, thereby inducing mechanical vibration of the related components of the microphone assembly 300. Thus, by collecting and converting the mechanical vibration signal, the external sound signal can be collected.

[0110] In addition, based on the cooperation between the first circuit board 310 and the protective net 330, the microphone 320 is firmly fixed to the first shell 110, so that the sound input channel of the microphone 320 can maintain coaxial sealed connection with the sound pickup channel 110a through the sound guide channel 310a; and the protective net 330 can prevent water, dust and other pollutants outside the device from invading the microphone assembly 300 through the sound pickup channel 110f, thereby providing protection for the normal operation of the microphone assembly 300.

[0111] In other embodiments, the microphone assembly 300 may also adopt other structural forms. For example, the protective net 330 is omitted, and the microphone 320 is arranged on the side of the first circuit board 310 facing the sound pickup channel 110f. With the help of the structural relationship between the first circuit board 310 and the first shell 110, the sound input channel of the microphone 320 can be directly sealed and connected to the sound pickup channel 110f.

[0112] It should be noted that those skilled in the art should be aware of the basic working principle of an air conduction microphone, so the specific process and principle of the microphone assembly 300 collecting sound signals will not be described here.

[0113] For one example, see Figure 2 and Figure 8 The number of the sound pickup channels 110f and the microphone assembly 300 is set to two. The two sound pickup channels 110f correspond one-to-one to the sound input channels of the two microphone assemblies 300 and are sealed and connected. Taking the sound pickup channels 110f as an example, the sound input ends of the two sound pickup channels 110f are arranged at intervals from each other, so that they can cooperate with the microphone assembly 300 to collect external sound signals at different positions or different directions.

[0114] For example, in some embodiments, based on the arc surface structure adopted by the third side wall of the shell assembly 100 (i.e., the fifth shell wall 110e), the sound input ends of the two sound pickup channels 110f are arranged at intervals on the outer surface of the third side wall in the first direction, so that the microphone assembly 300 can collect external sound signals from different directions.

[0115] In other embodiments, depending on the functional configuration or structural form of the microphone assembly 300, the two sound pickup channels 110f can also be sealed and connected to the sound input channel of the same microphone assembly 300 to meet different application requirements.

[0116] For one example, see Figure 7 、 Figure 9 and Figure 10The inner wall of the first shell 110 (for example, the surface of the fifth shell wall 110e) is provided with a second fixing structure, which may include a fixed retaining wall 151 protruding from the inner wall surface of the first shell 110, for example, the fixed retaining wall 151 and the first shell 110 are an integral structure; a receiving groove is formed between the fixed retaining wall 151 and the inner wall surface of the fifth shell wall 110e; wherein, at least a portion of the microphone assembly 300 (specifically, the end where the microphone 320 is located) is received and fixed in the receiving groove, and the sound output end of the pickup channel 110f is located within the outline of the receiving groove.

[0117] On the one hand, with the help of the receiving groove formed between the fixed retaining wall 151 and the inner wall surface of the first shell 110, the installation position of the microphone assembly 300 can be quickly located to provide support for the structural combination of the microphone assembly 300 and the first shell 110; on the other hand, the fixed retaining wall 151 can be used to restrict the microphone assembly 300 to a preset position within the accommodating cavity 100a (i.e., within the receiving groove), thereby ensuring that the sound input channel of the microphone 320 can maintain coaxial sealed communication with the sound pickup channel 110f.

[0118] In other embodiments, the second fixing structure may also adopt other suitable structural forms. For example, under the premise of ensuring that the microphone assembly 300 is sealed and connected to the sound pickup channel 110f, the second fixing structure may be a snap-fit ​​structure provided on the inner wall of the first housing 110 to fix the microphone assembly 300 in the position corresponding to the sound pickup channel 110f; or the second fixing structure may be a groove structure provided on the inner wall of the third side wall to insert at least a portion of the microphone assembly 300 into the space of the second fixing structure. All of these details are not detailed here.

[0119] For one example, see Figure 2 、 Figure 3 、 Figures 8 to 10 The core assembly includes a control panel assembly 200 and a microphone assembly 300; wherein the control panel assembly 200 is fixedly connected to the inner wall of the first shell 110 and electrically connected to the microphone assembly 300, mainly used to receive the sound signal collected by the microphone assembly 300, and convert the sound signal into an electrical signal and output it to the speaker device.

[0120] Exemplarily, there are two microphone assemblies 300, which are spaced apart and arranged on opposite sides of the control board assembly 200 and are electrically connected to the control board assembly 200. For example, the control board assembly 200 is arranged between the two microphone assemblies 300 in the first direction.

[0121] More specifically, see Figures 8 to 10The control board assembly 200 includes a second circuit board 210, and the material hardness of the second circuit board 210 is set to be greater than the material hardness of the first circuit board 310. For example, the first circuit board 310 can adopt a flexible printed circuit board (Flexible Printed Circuit, referred to as FPC), and the second circuit board 210 can adopt a rigid printed circuit board (Printed Circuit Boards, referred to as PCB).

[0122] For ease of description, the two opposite ends of the first circuit board 310 in its length direction (or 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 (for example, welded) to the second circuit board 210.

[0123] On the one hand, the flexible-board-hard-board structural connection between the microphone assembly 300 and the control board assembly 200 enhances the compactness of the structural connection between the microphone assembly 300 and the control board assembly 200, saving structural space in the accommodating cavity 100a. Secondly, the flexible deformation of the first circuit board 310 compared to the second circuit board 210 allows it to adapt to the structural form of the interior space of the housing assembly 100 (e.g., the inner surface of the first housing 110), flexibly adjusting the relative mounting position between the microphone assembly 300 and the control board assembly 200. For example, this facilitates the direct mounting and fixing of the microphone assembly 300 to the first housing 110. Thirdly, it facilitates the disassembly of the microphone assembly 300 and the control board assembly 200, enabling the recycling of important electronic components, such as the control chip in the control board assembly 200.

[0124] On the other hand, in some embodiments where the shell assembly 100 adopts a conformal structure, since the third side wall (i.e., the third shell wall 110e) adopts a curved surface structure, the control panel assembly 200 and the microphone assembly 300 have different orientations or produce different height differences relative to the inner surface of the third side wall, etc., and the connection form of a soft board combined with a hard board between the two can well adapt to the differences in installation position and installation form between the control panel assembly 200 and the microphone assembly 300, so as to conveniently, quickly and accurately complete the installation and fixation of the control panel assembly 200 and the microphone assembly 300.

[0125] For one example, see Figure 7 and Figure 10The inner surface of the first shell 110 (specifically the fifth shell wall 110e) is provided with a third fixing structure, which is mainly used to support and fix the second circuit board 210 at a preset position in the accommodating cavity 100a, so that a sufficient spacing distance is maintained between the control board assembly 200 and the microphone assembly 300.

[0126] For example, see Figure 7 and Figure 10 The third fixing structure may 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 positioning through holes 210a corresponding to the positions of the support columns 161; the support columns 161 are inserted into the positioning through holes 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 form of facing the inner surface of the fifth shell wall 110e at intervals.

[0127] On one hand, by means of the cooperation between the support column 161 and the positioning through hole 210a, a fixed spacing distance can be provided between the control board assembly 200 and the microphone assembly 300 to avoid signal interference between the two.

[0128] On the other hand, the support columns 161 can create a certain structural gap between the second circuit board 210 and the inner wall of the first housing 110, providing structural space for the key assembly 400 to be assembled within the first housing 110. For example, the second circuit board 210 can be arranged transversely within the accommodating cavity 100a along the third direction (or the width of the device body) (this can also be understood as the plane where the second circuit board 210 is located being substantially perpendicular to the third and fourth housing walls 110c, 110d). This allows the structural gap between the second circuit board 210 and the fifth housing wall 110e to serve as structural installation space and movement space for the key assembly 400. This facilitates controlling the overall width and thickness of the device body and facilitates the step-by-step fixing and assembly of the microphone assembly 300 and the control board assembly 200 to the first housing 110.

[0129] In other embodiments, the third fixing structure may also adopt other suitable structural forms, for example, the support column 161 is protruding from the second circuit board 210, and a slot structure is provided on the inner wall surface of the first shell 110 for the support column 161 to be inserted and fixed; it will not be repeated here.

[0130] For one example, see Figures 4 to 6 and combined Figure 10 and Figure 12A first limiting structure is further provided 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 generating structural deformation at the junction of each other, so as to avoid squeezing the control board assembly 200 (specifically, the second circuit board 210) due to structural deformation of the shell.

[0131] For example, see Figures 4 to 6 The first shell 110 and the second shell 120 both adopt a shell-type structure, and the surfaces of the first shell 110 and the second shell 120 that are relatively in contact with each other in the second direction are defined as joint surfaces; wherein, the joint surface of the first shell 110 is provided with a first limiting flange 171 that protrudes roughly along the second direction toward the side where the second shell 120 is located, and the joint surface of the second shell 120 is provided with a second limiting flange 172 that protrudes roughly along the second direction toward the side where the first shell 110 is located.

[0132] 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 facing 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).

[0133] By means of the second limiting flange 172, the first limiting flange 171 is pressed against from the inner side of the accommodating cavity 100a, thereby forming a first limiting structure. This can prevent the first shell 110 from shrinking and deforming in the third direction at the opening due to the influence of the material properties itself, thereby preventing the control board assembly 200 (specifically, the second circuit board 210) from being squeezed; at the same time, it can also enhance the structural connection strength of the first shell 110 and the second shell 120 at the joint surface, reduce or eliminate the structural gap between the first shell 110 and the second shell 120, and ensure the integrity of the overall outline of the shell assembly 100.

[0134] In some embodiments, the first limiting structure can also be arranged in other structural forms between the joint surfaces of the first shell 110 and the second shell 120. For example, a flange is provided on the joint surface of the second shell 120, and a slot is provided on the joint surface of the first shell 110 at a position corresponding to the flange. The flange is inserted into the slot to form a first limiting structure, which can also prevent the first shell 110 from deforming in the third direction, thereby preventing the first shell 110 from squeezing the first component (such as the control board component 200).

[0135] In some embodiments, for the same requirement as protecting the control panel assembly 200, the first limiting flange 171 may also be located on the side of the second limiting flange 172 facing the accommodating cavity 100a in the third direction, that is, with the accommodating cavity 100a as a reference base, the first limiting flange 171 is located inside the accommodating cavity 100a; with the help of the first limiting flange 171, the second limiting flange 172 is pressed against the inner side of the accommodating cavity 100a, which can prevent the second shell 120 from generating structural deformation of the opening shrinkage in the third direction, thereby squeezing the second component (such as the first interface component 500, etc.) arranged on the second shell 120.

[0136] In some embodiments, the first limiting structure may include a flange and a slot, and the flange and the slot are simultaneously arranged on the joint surface of the first shell 110 and the second shell 120. The structural relationship in which the flange and the slot are inserted one by one can prevent the first shell 110 and the second shell 120 from being deformed in the third direction, thereby protecting the first component and the second component from being squeezed by the shell.

[0137] For one example, see Figures 4 to 6 The number of the first limiting structures is set to multiple groups, and the multiple groups of first limiting structures are arranged on the two opposite sides of the accommodating cavity 100a in the third direction, for example, on the two opposite sides of the second circuit board 210 in the third direction, to enhance the prevention of deformation of the first shell 110 and ensure the stability of the connection between the first structures.

[0138] Of course, the first limiting structures can also be arranged at intervals around the second direction to limit the shell deformation from the third direction, the first direction and other directions, ensuring that the joint surfaces of the first shell 110 and the second shell 120 can stably abut each other.

[0139] For one example, see Figures 4 to 6 The joint surface of the first shell 110 or the joint surface of the second shell 110 is also provided with an avoidance structure, which is mainly used to avoid part of the first component or the second component during the assembly process of the first shell 110 and the second shell 120 to adapt to the space size requirements of the first component or the second component for the accommodating cavity 100a.

[0140] Exemplarily, the first limiting flange 171 is located on the side of the second limiting flange 172 facing away from the accommodating cavity 100a in the third direction. The avoidance structure can be a second avoidance notch 173 arranged on the second limiting flange 172, or 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.

[0141] Taking the second avoidance notch 173 as an example, during the assembly process of the first shell 110 and the second shell 120, the second avoidance notch 173 can be used to enable the second shell 120 to adapt to the outline size of the second circuit board 210, so as to avoid or accommodate the part of the second circuit board 210 that protrudes relatively toward the outside of the shell assembly 100 in the third direction; this not only ensures that the joint surface 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, but also avoids structural extrusion or structural interference to the control board assembly 200, etc.

[0142] For one example, see Figures 8 to 11 The core assembly includes a control panel assembly 200, a microphone assembly 300 and a key assembly 400; wherein, the first shell 110 is provided with a key window 110g arranged through the fifth shell wall 110e, and the key window 110g connects the accommodating cavity 100a with the outside of the shell assembly 100; for example, in an embodiment where the core assembly includes two microphone assemblies 300, the key window 110g can be arranged between the two sound pickup channels 110f along the first direction; the key assembly 400 includes an operation button 410 movably connected to the inner wall surface of the first shell 110, and at least a portion of the operation button 410 is exposed through the key window 110g and protrudes from the first shell 110.

[0143] For example, the control panel assembly 200 is disposed on a side of the operating button 410 that faces away from the key window 110g, and the control panel assembly 200 is configured with a key switch for cooperating with the operating button 410. By manipulating the operating button 410 to move relative to the first housing 110, the operating button 410 can be used to press the key switch of the control panel assembly 200 to input a preset command.

[0144] By connecting the button assembly 400 to the first shell 110 and using the first shell 110 as an installation carrier for the button assembly 400, it is possible to fully utilize the structure and space of the shell assembly 100, reduce the number of components configured, and provide support for the lightweight and miniaturized design of wearable devices.

[0145] For one example, see Figure 11A first rotating shaft structure is provided between the operating button 410 and the first housing 110. This rotating shaft structure may include a rotating shaft protrusion 181 and a rotating shaft slot 420. The rotating shaft slot 420 is provided on opposite sides of the operating button 410 in the third direction. The rotating shaft protrusion 181 protrudes from the inner wall of the first housing 110 (e.g., the third housing wall 110c and the fourth housing wall 110d) and is aligned and inserted into the rotating shaft slot 420. The radially opposite ends of the first rotating shaft structure of the operating button 410 are the first and second ends of the operating button 410, respectively. Accordingly, the key switch of the control panel assembly 200 may be provided at a position corresponding to the first end, the second end, or both ends of the operating button 410.

[0146] Therefore, based on the existence of the first rotating shaft structure, the operation button 410 is subjected to external force and rotates around the first rotating shaft structure relative to the first shell 110, so that one of the first end and the second end of the operation button 410 protrudes from the first shell 110 or is tilted relative to the first shell 110, and the other rotates toward the side of the control panel assembly 200 to press and trigger the corresponding button switch, thereby realizing the input of command information.

[0147] For example, see Figure 11 The control board assembly 200 includes a first circuit board 210, a first switch 220 and a second switch 230; wherein the first circuit board 210 is arranged at intervals on the side of the operation button 410 facing away from the key window 110g (for example, supported and fixed to the first shell 110 by the support column 161), and the first switch 220 and the second switch 230 are arranged on the side of the first circuit board 210 facing the operation button 410, and the first switch 220 corresponds to the first end of the operation button 410, and the second switch 230 corresponds to the second end of the operation button 410.

[0148] By pressing the first end of the operation button 410 toward the inside of the shell assembly 100, the first end of the operation button 410 can touch the corresponding first switch 220 to realize the input of a preset instruction; in this process, the operation button 410 rotates relative to the first shell 110 along the first preset direction (for example, counterclockwise) around the first rotating shaft structure, and the second end of the operation button 410 protrudes from the outer surface of the first shell 110 or is tilted relative to the first end of the operation button 410.

[0149] Conversely, by pressing the second end of the operation button 410 toward the inside of the shell assembly 100, the second switch 220 can be triggered to input a preset instruction; in this process, the operation button 410 rotates relative to the first shell 110 around the first rotation axis structure along a second preset direction (for example, clockwise) opposite to the first preset direction, and the first end of the operation button 410 protrudes from the outer surface of the first shell 110 or is tilted relative to the second end of the operation button 410.

[0150] In some embodiments, the first end and the second end of the operating button 410 can be arranged symmetrically about the first rotating shaft structure, thereby ensuring the smooth rotation of the operating button 410 relative to the first shell 110, and also facilitating the selection or control of the position of the button switch (such as the first switch 220 and the second switch 230) on the second circuit board 210.

[0151] See also Figure 1 、 Figure 2 and Figure 8 In some embodiments where the housing assembly 100 employs a contoured structure, the third sidewall (also known as the fifth housing wall 110e) employs a curved surface. The plane on which the control board assembly 200 (specifically, the second circuit board 210) resides is parallel to the rotation axis of the operating button 410 or the axis of the first rotating shaft structure. This makes it difficult for the first and second ends of the operating button 410 to protrude consistently above the outer surface of the third sidewall, which can easily degrade the operating experience of the button assembly 400 and lead to issues such as misoperation.

[0152] For ease of description, taking the device in a worn state as a reference, the first end of the operation button 410 can be understood as the end of the operation button 410 that is relatively low in the first direction or in the up-down direction of the user; Figure 11 A button protrusion 440 protruding toward the outside of the housing assembly 100 is provided on the outer surface of the first end of the operation button 410. For example, the button protrusion 440 is provided to protrude from the outer surface of the first end of the operation button 410 along the second direction.

[0153] Therefore, with the help of the button protrusion 440, not only can the height difference between the two ends of the operation button 410 relative to the shell assembly 100 be adjusted or compensated to achieve the purpose of improving the operating experience, but also the risk of misoperation of the operation button 410 can be reduced.

[0154] In other embodiments, the button protrusion 440 may also be set to protrude from the second end of the operation button 410, or the first end and the second end of the operation button 410 may adopt different structural forms; this may also improve the operating experience and reduce misoperation, thereby meeting different application requirements.

[0155] In some embodiments where the first shell 110 and the second shell 120 are made of polyimide material, the button assembly 400 (specifically, the operation button 410) can also adopt an integrated structure made of polyimide material. This can make the materials of the various components of the device body close to consistency, 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.

[0156] For one example, see Figure 2 、 Figures 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 connection port 120f and a second connection port 120g for connecting the accommodating cavity 100a with the outside of the shell assembly 100; wherein, the first connection port 120f is set through the first side wall of the shell assembly 100 (that is, the first shell wall 110a and the sixth shell wall 120a), and the second connection port 120g is set through the eighth shell wall 120c of the second shell 120; when the device is in the wearing state, the first connection port 120f is located at the top of the shell assembly 100 in the up and down direction of the user and faces the front side of the user, and the second connection port 120g is located in the middle of the shell assembly 100 in the left and right direction of the user and faces the back side of the user's ear.

[0157] The first interface assembly 500 includes a first interface member 510 and a first fixing member 520. The first interface member 510 has opposing interface ends and connection terminals. The first interface member 510 is positioned within the accommodating cavity 100a with its interface end facing the first connection port 120f. This allows the connector of the speaker device (specifically, the wearable assembly 820) to extend into the accommodating cavity 100a through the first connection port 120f, thereby adapting to and connecting with the first interface member 510 in a removable or fixed manner. The connection terminals of the first interface member 510 are used to connect to the control board assembly 200, for example, by connecting to the second circuit board 210 via a wire assembly.

[0158] The first fixing member 520 cooperates with the first interface member 510 to secure the first interface member 510 to the second housing 120. For example, a fourth fixing structure 140 is provided between the inner walls of the second housing 120 (specifically, the tenth housing wall 120e). The fourth fixing structure 140 can be configured to restrict and secure the first fixing member 520 (together with the first interface member 510) to the second housing 120 from at least two different directions. The first interface member 510 is secured to the first fixing member 520.

[0159] The second interface assembly 600 includes a second interface member 610 and a second fixing member 620; wherein, the second interface member 610 has a relative open end and a wiring end, and the second interface member 610 is arranged in the accommodating cavity 100a with its interface end facing the second connecting port 120g. The connector of the external control device can extend into the accommodating cavity 100a through the second connecting port 120g and be adapted to connect to the second interface member 610 in a pluggable and detachable manner.

[0160] The second fixing member 620 cooperates with the second interface member 610 to fix the second interface member 610 to the second shell 120; for example, the inner wall of the second shell 120 (specifically, the tenth shell wall 120e) is provided with a fifth fixing structure 150, and the second fixing member 620 is fixedly connected to the fifth fixing structure 150 to clamp and fix the second interface member 610 between the second fixing member 620 and the inner wall surface of the second shell 120.

[0161] In some embodiments, the first fixing member 520 or the second fixing member 620 may be omitted, and the first interface member 510 or the second interface member 610 may be fixed to the second shell 120 by providing a snap-fit ​​structure or the like on the inner wall of the second shell 120; or the first interface member 510 or the second interface member 620 may be directly fixed to the second shell 120 by gluing, welding, or the like; all these will not be elaborated here.

[0162] Based on this, using the second shell 120 as the installation carrier of the first interface component 500 and the second interface component 600 can fully utilize the structural space of the shell component 100, making the structure of the wearable device more compact, which is conducive to the lightweight and miniaturized design of the wearable device.

[0163] For some examples, see Figure 14 Since the second interface component 600 usually does not need to be connected to an external control device when the wearable device is in normal use, in order to ensure the overall structural sealing or contour integrity of the device, a seal 630 can be set at the second connection port 120g. The seal 630 can be a sealing plug made of plastic material or other suitable structural components. By inserting the seal 630 into the second connection port 120g or pulling it out from the second connection port 120g, the second connection port 120g can be selectively closed and opened.

[0164] In some embodiments where the speaker device is used as a consumable component of a wearable device, or in some scenarios where the speaker device is not assembled and connected to the device body, the seal 630 can also be used to temporarily seal the first connection port 120f or the second connection port 120g.

[0165] In some embodiments where the housing assembly 100 is made of polyimide material, the first fixing member 520 and the second fixing member 620 are both integral structures made of polyimide material. This allows the materials of the various components of the device body to be nearly consistent, which is not only beneficial to the processing and manufacturing of related components, but also ensures that the related components have good biocompatibility and sufficient mechanical strength.

[0166] As mentioned above, the first interface component 500 or the second interface component 600 can be omitted; therefore, in some embodiments, the first interface component 500 or the second interface component 600 can be referred to as an interface component, which can be used to connect external devices, such as mobile phones, computers, speaker devices, etc.; the first interface part 510 or the second interface part 610 is referred to as an interface part, and the first fixing part 520 or the second fixing part 620 is referred to as a fixing part.

[0167] For one example, see Figures 2 to 4 、 Figure 6 and Figure 15 The core assembly includes a battery assembly 700, and the shell assembly 100 is provided with a battery window 120h that connects the accommodating 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; as for the shell assembly 100, the battery window 120h can be a strip 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 the direction around the third direction of the shell assembly 100.

[0168] The battery assembly 700 includes a battery holder 710 for placing the battery 730 and an electrode spring 720 for electrically connecting the control board assembly 200. Figure 15 A second rotating shaft structure 750 and a locking structure 760 are formed between the battery holder 710 and the second housing 120. The second rotating shaft structure 750 is used to establish a relatively rotatable structural connection between the battery holder 710 and the second housing 120, allowing the battery holder 710 to rotate relative to the second housing 120 about the second rotating shaft structure 750 (the direction of the axis of the second rotating shaft structure 750 or the rotation axis of the battery holder 710 is considered the third direction), thereby allowing the battery holder 710 to enter and exit the accommodating 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, to keep the battery holder 710 within the accommodating 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.

[0169] The electrode spring clip 720 is arranged in the accommodating cavity 100a and is fixedly connected to the second shell 120; for example, the number of the electrode spring clips 720 is set to two, and the two electrode spring clips 720 are arranged on opposite sides of the battery window 120h in the third direction; when the battery holder 710 is locked to the second shell 120 by the locking structure 760, so that the battery 730 placed on the battery holder 710 is located in the accommodating cavity 100a, one end of the two electrode spring clips 720 can elastically support the positive and negative poles of the battery 730 respectively, and the other end of the two electrode spring clips 720 can be electrically connected to the control board assembly 200 (for example, the second circuit board 210) through the wire assembly.

[0170] On the one hand, by using the second shell 120 as the installation carrier of the battery assembly 700 and distributing the components of the battery assembly 700 (i.e., the battery holder 710 and the electrode spring 720) in a dispersed manner on the second shell 120, the structural space of the second shell 120 or the shell assembly 100 can be fully utilized, which is conducive to achieving a lightweight and miniaturized design of the wearable device.

[0171] On the other hand, the battery holder 710 can be rotated out of the shell assembly 100 through the battery window 120h, which makes it easier to replace the battery 730. After the battery holder 710 is rotated into the accommodating cavity 100a, it can adapt to the structural form of the battery window 120h and achieve the closure of the battery window 120h, thereby maintaining the integrity of the outer contour structure of the device body.

[0172] It should be noted that the description of battery 730 in this embodiment is only for the purpose of understanding the structural structure and functional principle of battery holder 710, and does not necessarily mean that battery 730 is a component of battery assembly 700. In other words, in some embodiments, battery 730 can be a component of battery assembly 700; in other embodiments, battery 730 can also be a consumable component used with a wearable device.

[0173] In some embodiments where the shell assembly 100 adopts a conformal structure, since the battery window 120h is equivalent to a strip window set through the second side wall and the fourth side wall of the shell assembly 100, the length trajectory of the battery window 120h is roughly an arc segment; the battery holder 710 can be configured to adapt to the arc shape of the battery window 120h, so as to achieve the closure of the battery window 120h with the help of the battery holder 710, thereby ensuring the integrity of the outer contour structure of the device body.

[0174] In other embodiments, the battery holder 710 may also adopt other structural forms. For example, the battery holder 710 can be set to a cover-type structure that is roughly the same as or matches the structural form of the battery window 120h, and the battery 730 is placed on the second shell 120 in a detachable form and is located in the accommodating cavity 100a. By disassembling and assembling the battery holder 710, the battery window 120h can be opened or closed to replace the battery 730.

[0175] In some embodiments, the battery holder 710, first housing 110, and second housing 120 are each integrally formed from a polyimide material. This ensures that the battery holder 710 and housing assembly 100, as components that contact human skin, possess good biocompatibility and stable structural strength. Furthermore, the consistent material composition of the device's main components facilitates the fabrication and coordination of related components.

[0176] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
