DETAILED DESCRIPTION

[0039] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. 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.

[0040] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0041] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0042] This article mainly takes the in-ear hearing aid as an example to describe the wearable device provided in the embodiments of the present application; 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, headphones, glasses and other devices.

[0043] See also Figure 1 The wearable device includes a housing assembly 100, a movement assembly, a speaker device, and other functional components as needed.

[0044] The core assembly can be understood as a collection of related components that realize the main functions of the wearable device. For example, the core assembly 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 assembly is arranged in the shell assembly 100, so as to be combined with the shell assembly 100 to form a complete functional structure; for the sake of convenience of distinction and description, the combined structure of the shell assembly 100 and the core assembly is defined as the device body.

[0045] 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.

[0046] For example, see 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 core component, and is mainly used to establish a signal connection relationship between the core component and the speaker component 810.

[0047] The wearable component 820 can be a flexible cable with a signal transmission function, or other wires with both a signal transmission function and a shape memory function. One end of the wearable component 820 is fixed and electrically connected to the speaker component 810, and the other end of the wearable component 820 can be connected to the housing component 100 in a detachable or non-detachable manner and electrically connected to the movement component.

[0048] 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.

[0049] 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.

[0050] It is understood that when a wearable device is powered on, the cooperation between the core assembly and the speaker device can achieve the conversion between sound signals (such as mechanical vibration signals) and electrical signals, so that the user can hear the sound through the ears. Generally speaking, mechanical vibrations can act on the user's eardrum and auditory nerve based on the principle of air conduction, mainly 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. With respect to the sound heard by the user, the former can be referred to as "air-conducted sound," and the latter can be simply referred to as "bone-conducted sound."

[0051] Based on this, by selecting and configuring the specific functional structures of the movement components and the speaker device, the wearable device can form both air-conducted sound and bone-conducted sound, and can also achieve air-conducted sound and bone-conducted sound at the same time.

[0052] 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: a "first direction", a "second direction" and a "third direction".

[0053] For example, when the wearable device is in a certain 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.

[0054] For example, when the wearable device is normally worn between the back of the ear and the head, with the user as a reference, 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.

[0055] 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 matched 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 is connected to the second shell 120.

[0056] 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.

[0057] The microphone assembly 300 is electrically connected to the control board assembly 200 and is respectively fixed to the first shell 100; 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.

[0058] 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.

[0059] The button assembly 400 is movably connected to the first shell 100 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.

[0060] 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.

[0061] The second interface assembly 600 is primarily used to connect to an external control device (such as a mobile phone or computer) 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.

[0062] In some embodiments, other functional components may be added to the movement 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 board assembly 200 through the wearable assembly 820; for 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 with the help of the wireless communication module.

[0063] That is, the core assembly may include one or more of the control board assembly 200 , the microphone assembly 300 , the button assembly 400 , the first interface assembly 500 , the second interface assembly 600 and the battery assembly 700 .

[0064] 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 .

[0065] 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.

[0066] 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.

[0067] Based on this, with 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 arranged in different parts of the shell assembly 100.

[0068] On the one hand, compared with the related art, in which an internal skeleton independent of the shell assembly 100 is used as the installation carrier of the movement assembly, the present application can fully utilize the shell structure and space, reduce the number of internal components of the device, and thus facilitate the miniaturization and lightweight design of the wearable device.

[0069] On the other hand, based on the structural form of the dispersed arrangement of the movement components, not only can the wearable device be quickly disassembled and assembled, but also by disassembling and assembling the first shell 110 and the second shell 120, the first component and the second component can be specifically disassembled, maintained, recycled and reused.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] For example, see Figures 4 to 7 The assembly structure includes a second fixing structure and a first positioning structure; wherein the second 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 second fixing structure to enhance the structural combination strength of the first shell 110 and the second shell 120.

[0080] The second 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 .

[0081] 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.

[0082] 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).

[0083] 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.

[0084] 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.

[0085] With the help of the mutual cooperation between the second 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.

[0086] 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.

[0087] 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.

[0088] In some embodiments, the second fixing structure and the first positioning structure may also adopt other structural forms.

[0089] 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 second fixing structure and the first positioning structure to achieve assembly and fixation of the first shell 110 and the second shell 120 .

[0090] 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 second 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.

[0091] In some embodiments, the second 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.

[0092] 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.

[0093] 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 second 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 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.

[0094] By placing the second 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.

[0095] In some embodiments, the control panel assembly 200, the microphone assembly 300, the button 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-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.

[0096] 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.

[0097] For one example, see Figures 2 to 5The first shell 110 and the second shell 120 both adopt a shell-type structure, and 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.

[0098] For ease of distinction and description, the two opposing walls of the first housing 110 in the first direction are defined as the first housing wall 110a and the second housing wall 110b, the two opposing walls in the third direction are defined as the third housing wall 110c and the fourth housing wall 110d, and the wall connecting the first, second, third, and fourth housing walls 110a, 110b, 110c, and 110d in the second direction is defined as the fifth housing wall 110e. The two opposing walls of the second housing 120 in the first direction are defined as the sixth and seventh housing walls 120a, 120b, the two opposing walls in the third direction are defined as the eighth and ninth housing walls 120c, 120d, and the wall connecting the sixth, seventh, eighth, and ninth housing walls 120a, 120b, 120c, and 120d in the second direction is defined as the tenth housing wall 120e.

[0099] 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.

[0100] See also Figure 2 and Figure 3 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] By applying a pressing force toward the control panel assembly 200, the button assembly 400 can be urged to contact a key switch on the control panel assembly 200, thereby inputting a preset command. Of course, the button assembly 400 can also include a switch component capable of generating an electrical signal. The button assembly 400 is electrically connected to the control panel assembly 200, and triggering the button assembly 400 inputs command information to the control panel assembly 200.

[0106] See also Figure 2 and Figure 6 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 and communicate with the first connection port 120f, and 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.

[0107] 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).

[0108] See also Figure 2 and Figure 6 The second interface assembly 600 is fixedly connected to the second shell 120 (for example, fixed to the fourth side wall) in a manner that is at least partially exposed on the fifth side wall and arranged within the accommodating cavity 100a. 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 directly opposite and in communication with the second connection port 120g, 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.

[0109] See also Figures 2 to 4 、 Figure 6 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.

[0110] 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.

[0111] 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.

[0112] For another example, by setting the third side wall to a curved surface structure and arranging the two microphone assemblies 300 on opposite sides of the button assembly 400 or the control panel assembly 200 in the first direction, the sound pickup channels 110f corresponding to the two microphone assemblies 300 can be directed in 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.

[0113] In some embodiments, 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 the wearing component 820, and the speaker component 810 is inserted into the user's ear canal:

[0114] 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.

[0115] Among them, see Figures 1 to 3 and Figure 5 The dimensions of the housing assembly 100 in the first direction are configured to be larger than those in the second and third directions. The third and fourth sidewalls are configured to have curved surfaces that adapt to the physiological structure of the area where the back of the ear meets the head. The geometric centerline of the housing assembly 100 in the first direction is configured as an arc segment.

[0116] In this way, based on the size differences of the shell component 100 in different directions and the structural form of the side wall, the outer contour of the shell component 100 or the device body is constructed into a prosthetic 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 as to be worn on the ear in the form of being clamped or hung on the ear.

[0117] 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.

[0118] 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 .

[0119] Compared with related technologies, the body shell of wearable devices usually adopts materials such as polycarbonate (PC for short), 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 polyimide materials, the structural form (including the appearance) of the shell assembly 100 can be made more stable, and the thickness of the shell wall 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.

[0120] For one example, see Figures 2 to 5 、 Figures 7 to 10 The housing assembly 100 includes a first housing 110 , and the core assembly includes a key assembly 400 and a control panel assembly 200 .

[0121] The first shell 110 adopts a shell structure with an opening, and a key window 110g is provided on the shell wall of the first shell 110 to connect the shell space (or the accommodating 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.

[0122] The button assembly 400 includes an operation button 410, which is arranged in the shell space of the first shell 110 and is movably connected to the inner wall of the first shell 110; at the same time, at least part of the operation button 410 is exposed through the button window 110g and protrudes from the first shell 110; it can also be understood that the operation button 410 covers the button window 110g and at least part of it is arranged outside the first shell 110 through the button window 110g.

[0123] The control panel assembly 200 is arranged on the side of the operation button 410 facing away from the key window 110g, and the control panel assembly 200 is configured with a key switch for cooperating with the operation button 410; by manipulating the operation button 410 to move relative to the first shell 110, the operation button 410 can be used to press the key switch of the control panel assembly 200 to realize the input of the preset command.

[0124] By movably connecting the button assembly 400 to the inner wall of the first shell 110, the first shell 110 can be directly used as an installation carrier for the button assembly 400 without the aid of other connecting components. This is not only conducive to making full use of the structure and space of the shell assembly 100, but also can effectively reduce the number of components configured in the wearable device (such as the internal skeleton), thereby providing support for convenient and quick disassembly and maintenance of the button assembly 400 and realizing a lightweight and miniaturized design of the wearable device.

[0125] For one example, see Figure 10 A rotating shaft structure is provided between the operating button 410 and the first housing 110. This rotating shaft structure is disposed along the third direction between the operating button 410 and the third housing wall 110c, and between the operating button 410 and the fourth housing wall 110d. It is understood that the axial direction of the rotating shaft structure, or the direction of the rotating shaft structure's rotational axis, is the third direction. The operating button 410 has two opposing ends in the radial direction (e.g., the first direction) of the rotating shaft structure, namely, the first end and the second end of the operating button 410. Accordingly, the key switch of the control panel assembly 200 can be disposed at a position corresponding to the first end, the second end, or both ends of the operating button 410.

[0126] Therefore, based on the existence of the hinge structure, the operation button 410 is subjected to external force and rotates around the hinge 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.

[0127] For example, see Figure 10The control board assembly 200 includes a second circuit board 210, a first switch 220 and a second switch 230; wherein the second circuit board 210 is arranged at intervals on the side of the operation button 410 facing away from 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 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.

[0128] By pressing the first end of the operation button 410 toward the side where the second circuit board 210 is located, 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, since the operation button 410 rotates relative to the first shell 110 along the first preset direction (for example, counterclockwise) around the rotating shaft structure, the second end of the operation button 410 can protrude from the outer surface of the first shell 110 or be tilted relative to the first end of the operation button 410.

[0129] Conversely, by pressing the second end of the operation button 410 on the side where the second circuit board 210 is located, the second switch 220 can be triggered to input a preset instruction; in this process, since the operation button 410 rotates relative to the first shell 110 around the shaft structure along a second preset direction (for example, clockwise) opposite to the first preset direction, the first end of the operation button 410 will protrude from the outer surface of the first shell 110 or be tilted relative to the second end of the operation button 410.

[0130] In some embodiments, the first end and the second end of the operating button 410 can be arranged symmetrically about the rotating shaft structure, thereby ensuring the smooth rotation of the operating button 410 relative to the first shell 110, and also facilitating the identification of the position of the button switch on the control panel assembly 200.

[0131] For one example, see Figure 10 There are two rotating shaft structures, each comprising a mating rotating shaft protrusion 181 and a rotating shaft slot 420. The rotating shaft slot 420 is disposed on the outer surface of the operating button 410, for example, on two opposing surfaces of the operating button 410 in the third direction. The rotating shaft protrusion 181 is integrally formed with the first housing 110. For example, the rotating shaft protrusion 181 protrudes from the third housing wall 110c or the fourth housing wall 110d at a position corresponding to the rotating shaft slot 420. It can also be understood that, in the axial direction of the rotating shaft structure, the two rotating shaft structures are disposed on opposite sides of the operating button 410.

[0132] Of course, according to actual needs, the shaft protrusion 181 can also be provided to protrude from the surface of the operation button 410 , and the shaft slot 420 can be provided on the inner wall surface of the first shell 110 .

[0133] By inserting the rotating shaft protrusion 181 into the corresponding rotating shaft slot 420 , the operation button 410 can be connected to the first shell 110 and the operation button 410 can be rotated relative to the first shell 110 .

[0134] In other embodiments, the shaft structure may also adopt other suitable structures. For example, the shaft structure includes a shaft rod, and a shaft hole structure is provided through the positions corresponding to each other between the first shell 110 and the operation button 410. By passing the shaft rod through the shaft hole structure, a relatively rotatable structural connection relationship can be established between the first shell 110 and the operation button 410.

[0135] For one example, see Figure 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 rotates to a preset limit angle position, thereby limiting the rotation angle of the operation button 410.

[0136] Exemplarily, the first limiting structure includes a third limiting flange 430, which is protruding from the surface of the operating button 410 in the form of an integrally formed structure; for example, the third limiting flange 430 is protruding from the two opposite surfaces of the operating button 410 in the axial direction (or the third direction) of the rotating shaft structure; for another example, the third limiting flange 430 is protruding from the two opposite surfaces of the operating button 410 in the radial direction (or the first direction) of the rotating shaft structure.

[0137] When the operation button 410 is rotated to a certain angle along the first preset direction or the second preset direction, the third limiting flange 430 can be used to abut against the inner wall surface of the first shell 110 (for example, the inner surface of the fifth shell wall 110e) at the edge of the button window 110g to prevent the operation button 410 from continuing to rotate.

[0138] Thus, the third limiting flange 430 is utilized to limit the rotation angle of the operating button 410; on the one hand, by selecting and setting the rotation angle of the operating button 410, it can be ensured that when the operating button 410 is rotated to the extreme angle position, the first end or the second end of the operating button 410 can just completely trigger the corresponding button switch; on the other hand, it can avoid the first end or the second end of the operating button 410 completely protruding from the first shell 110, causing the key window 110g to be partially opened, thereby affecting the overall structural compactness and contour integrity of the device due to the internal space of the shell assembly 100 being connected to the outside.

[0139] For one example, see Figure 10The third limiting flange 430 protrudes from the two opposite surfaces of the operation button 410 in the axial direction of the rotating shaft structure; in the radial direction of the rotating shaft structure (for example, in the second direction), 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 a position close to the rotating shaft structure toward the side where the first end and the second end of the operation button 410 are located.

[0140] Therefore, the third limiting flange 430 can adapt to the rotation trajectory of the operating button 410, thereby achieving the effect of limiting the rotation angle of the operating button 410.

[0141] In some embodiments, the operation button 410 and the shell assembly 100 are both made of polyimide material. For example, the operation button 410, the first shell 110 and the second shell 120 are all an integrated structure made of polyimide material; this can ensure that the relevant components of the wearable device that come into contact with the human body have good biocompatibility and stable structural strength.

[0142] See also Figure 1 、 Figure 2 and Figure 8 The key window 110g is set through the fifth shell wall 110e of the first shell 110, and the fifth shell wall 110e as a whole or the outer wall of the fifth shell wall 110e is an arc surface structure that bulges toward the outside of the first shell 110 in the second direction; wherein the first end and the second end of the operation button 410 are the two opposite ends of the operation button 410 in the first direction; as for the control board assembly 200, the plane where 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 where the control board assembly 200 (specifically, the second circuit board 210) is located is parallel to the rotation axis of the operation button 410 or the axis center line of the rotation shaft structure.

[0143] In this way, based on the arc surface structural characteristics of the first shell 110, structural support can be provided for the first and second ends of the operation button 410 to protrude from the first shell 110, which is beneficial for the user to accurately and quickly identify the position of the operation button 410 on the first shell 110, thereby conveniently and quickly pressing the operation button 410.

[0144] Considering the curved surface structure adopted by the fifth shell wall 110e, the plane where the control board assembly 200 (specifically, the second circuit board 210) is located is usually parallel to the rotation axis of the operation button 410 or the center line of the shaft structure; this will make it difficult for the first end and the second end of the operation button 410 to protrude from the first shell 110 (i.e., the outer wall surface of the fifth shell wall 110e) to maintain consistency, which can easily reduce the operating experience of the button assembly 400 and cause problems such as misoperation.

[0145] For some examples, see Figure 8 and Figure 10 When the wearable device is in a worn state, 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 the up and down direction of the user; a button protrusion 440 is provided on the outer surface of the first end of the operation button 410, protruding toward the outside of the first shell 110, for example, the button protrusion 440 is provided on the outer surface of the first end of the operation button 410 protruding along the second direction.

[0146] Therefore, with the help of the button protrusion 440, not only can the height difference between the two ends of the operation button 410 and the outer surface of the first shell 110 (i.e., the outer wall surface of the fifth shell wall 110e) be adjusted or compensated to achieve the purpose of improving the operating experience, but it also helps to reduce the risk of misoperation of the operation button 410.

[0147] 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.

[0148] For one example, see Figure 7 and Figure 9 The inner surface of the first shell 110 (specifically the fifth shell 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 shell space of the first shell 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.

[0149] For example, see Figure 7 and Figure 9 The first fixing structure includes 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 at positions corresponding to 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.

[0150] Thus, the first fixing structure (specifically, the support column 161) can create a certain structural gap 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), providing structural space for the key assembly 400 to be assembled into the first housing 110. For example, the second circuit board 210 can be arranged transversely within the housing space of the first housing 110 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 housing wall 110c and the fourth housing wall 110d). This allows the structural gap between the second circuit board 210 and the fifth housing wall 110e to serve as the structural installation space and movable space for the key assembly 400. This not only facilitates controlling the overall width and thickness of the device body, but also facilitates the step-by-step fixing and assembly of the key assembly 400 and the control board assembly 200 into the first housing 110.

[0151] In other embodiments, the first 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.

[0152] For one example, see Figures 4 to 6 Combined with Figure 9 and Figure 10 A second limiting structure is further provided between the first shell 110 and the second shell 120; on the 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 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.

[0153] 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.

[0154] 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).

[0155] 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 second 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's own properties, 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.

[0156] In some embodiments, the second 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 second 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).

[0157] In some embodiments, the second 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.

[0158] For one example, see Figures 4 to 6 The number of the second limiting structures is set to multiple groups, and the multiple groups of second 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; in this way, it can further prevent the first shell 110 from being deformed, and is also beneficial to the stability of the structural connection between the first shell 110 and the second shell 120.

[0159] Of course, the second 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.

[0160] For one example, see Figures 4 to 6 The second limiting structure is also provided with a second avoidance notch 173. During the assembly process of the first shell 110 and the second shell 120, part of the first component or the second component can be avoided with the help of the second avoidance notch 173 to adapt to the space size requirements of the first component or the second component for the accommodating cavity 100a.

[0161] 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, and the second avoidance gap 173 can be a gap structure 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.

[0162] During the assembly 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 dimensions of the second circuit board 210, so as to avoid or accommodate the portion 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 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, but also avoids structural extrusion or structural interference to the control board assembly 200, etc.

[0163] 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.
