[0032] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0033] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0034] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0036] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0037] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0038] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0039] Figures 2a and 2b are perspective views of an exemplary wearable device.

[0040] The wearable device (200) may have the form of glasses that can be worn on a body part of the user (e.g., head). The wearable device (200) of FIGS. 2A and 2B may be an example of the electronic device (101) of FIG. 1. The wearable device (200) may include a head-mounted display (HMD). For example, the housing of the wearable device (200) (e.g., the housing (300) of FIG. 3A) may include a flexible material such as rubber and / or silicone that is in close contact with a portion of the user's head (e.g., a portion of the face that surrounds both eyes). For example, the housing (300) of the wearable device (200) may include one or more straps capable of being twined around the user's head, and / or one or more temples attachable to the ears of the head.

[0041] Referring to FIG. 2A, a wearable device (200) may include at least one display (250) and a frame (295) supporting at least one display (250).

[0042] The wearable device (200) can be worn on a part of the user's body. The wearable device (200) can provide augmented reality (AR), virtual reality (VR), or mixed reality (MR) that combines augmented reality and virtual reality to the user wearing the wearable device (200). For example, the wearable device (200) can display a virtual reality image provided from at least one optical device (282, 284) of FIG. 2B on at least one display (250) in response to a user's designated gesture acquired through the motion recognition cameras (260-2, 260-3) of FIG. 2B.

At least one display (250) may include a first display (250-1) and / or a second display (250-2) spaced apart from the first display (250-1). For example, the first display (250-1) and the second display (250-2) may be positioned at positions corresponding to the user's left and right eyes, respectively.

[0044] Referring to FIG. 2B, at least one display (250) can provide the user with visual information transmitted from external light and other visual information distinct from the visual information through a lens included in the at least one display (250). The lens can be formed based on at least one of a Fresnel lens, a pancake lens, or a multi-channel lens. For example, the at least one display (250) can include a first surface (231) and a second surface (232) opposite to the first surface (231). A display area can be formed on the second surface (232) of the at least one display (250). When the user wears the wearable device (200), external light can be transmitted to the user by being incident on the first surface (231) and transmitted through the second surface (232). As another example, at least one display (250) can display an augmented reality image combined with a virtual reality image provided from at least one optical device (282, 284) on a real screen transmitted through external light, in a display area formed on the second surface (232).

A user wearing the wearable device (200) can view an image displayed on at least one display (250).

[0047] The frame (295) may be configured as a physical structure that allows the wearable device (200) to be worn on the user's body. The frame (295) may be configured so that, when the user wears the wearable device (200), the first display (250-1) and the second display (250-2) can be positioned corresponding to the user's left and right eyes. The frame (295) may support at least one display (250). For example, the frame (295) may support the first display (250-1) and the second display (250-2) to be positioned corresponding to the user's left and right eyes.

[0048] Referring to FIG. 2A, the frame (295) may include a region (220) that at least partially contacts a part of the user's body when the user wears the wearable device (200).

The first pad (211) and the second pad (212) may be in contact with a portion of the user's nose, and the first temple (204) and the second temple (205) may be in contact with a portion of the user's face and a portion of the user's ear. The temples (204, 205) may be rotatably connected to the rim through the hinge units (206, 207) of FIG. 2B. The first temple (204) may be rotatably connected to the first rim (201) through the first hinge unit (206) disposed between the first rim (201) and the first temple (204). The second temple (205) may be rotatably connected to the second rim (202) through the second hinge unit (207) disposed between the second rim (202) and the second temple (205). The wearable device (200) can identify an external object (e.g., a user's fingertip) touching the frame (295) and / or a gesture performed by the external object by using a touch sensor, a grip sensor, and / or a proximity sensor formed on at least a portion of the surface of the frame (295).

[0050] The wearable device (200) may include hardwares that perform various functions (e.g., hardwares to be described later based on the block diagram of FIG. 4). For example, the hardwares may include a battery module (270), an antenna module (275), at least one optical device (282, 284), speakers (e.g., speakers 255-1, 255-2), a microphone (e.g., microphones 265-1, 265-2, 265-3), a light-emitting module (not shown), and / or a printed circuit board (PCB) (290) (e.g., a printed circuit board). The various hardwares may be arranged within a frame (295).

A first microphone (265-1) arranged on the bridge (203), a second microphone (265-2) arranged on the second rim (202), and a third microphone (265-3) arranged on the first rim (201) are illustrated in FIG. 2B, but the number and arrangement of the microphones (265) are not limited to the embodiment of FIG. 2B. When the number of microphones (265) included in the wearable device (200) is two or more, the wearable device (200) can identify the direction of the sound signal by using a plurality of microphones arranged on different portions of the frame (295).

[0052] At least one optical device (282, 284) can project a virtual object onto at least one display (250) to provide various image information to a user. For example, at least one optical device (282, 284) can be a projector. At least one optical device (282, 284) can be disposed adjacent to at least one display (250) or can be included within at least one display (250) as a part of at least one display (250). The wearable device (200) can include a first optical device (282) corresponding to a first display (250-1) and a second optical device (284) corresponding to a second display (250-2). For example, at least one optical device (282, 284) may include a first optical device (282) disposed at an edge of a first display (250-1) and a second optical device (284) disposed at an edge of a second display (250-2). The first optical device (282) may transmit light to a first waveguide (233) disposed on the first display (250-1), and the second optical device (284) may transmit light to a second waveguide (234) disposed on the second display (250-2).

[0053] The camera (260) may include a recording camera (260-4), an eye tracking camera (ET CAM) (260-1), and / or a motion recognition camera (260-2, 260-3). The recording camera (260-4), the eye tracking camera (260-1), and the motion recognition cameras (260-2, 260-3) may be positioned at different positions on the frame (295) and may perform different functions. The eye tracking camera (260-1) may output data indicating the position or gaze of the eyes of a user wearing the wearable device (200). For example, the wearable device (200) may detect the gaze from an image including the user's pupils obtained through the eye tracking camera (260-1). The wearable device (200) can identify an object (e.g., a real object and / or a virtual object) focused on by the user using the user's gaze acquired through the gaze tracking camera (260-1). The wearable device (200) that has identified the focused object can execute a function (e.g., gaze interaction) for interaction between the user and the focused object. The wearable device (200) can express a part corresponding to the eye of an avatar representing the user in a virtual space using the user's gaze acquired through the gaze tracking camera (260-1). The wearable device (200) can render an image (or screen) displayed on at least one display (250) based on the position of the user's eyes. For example, the visual quality of a first region related to the gaze within the image and the visual quality (e.g., resolution, brightness, saturation, grayscale, PPI) of a second region distinguished from the first region may be different from each other. The wearable device (200) can obtain an image having visual quality of a first area matching the user's gaze and visual quality of a second area using foveated rendering.For example, if the wearable device (200) supports an iris recognition function, user authentication can be performed based on iris information acquired using the gaze tracking camera (260-1). An example in which the gaze tracking camera (260-1) is positioned toward the user's right eye is illustrated in FIG. 2B, but the embodiment is not limited thereto, and the gaze tracking camera (260-1) may be positioned solely toward the user's left eye, or toward both eyes.

[0054] The capturing camera (260-4) can capture an actual image or background to be aligned with a virtual image in order to implement augmented reality or mixed reality content. The capturing camera (260-4) can be used to obtain a high-resolution image based on HR (high resolution) or PV (photo video). The capturing camera (260-4) can capture an image of a specific object existing at a location viewed by a user and provide the image to at least one display (250). The at least one display (250) can display a single image in which information about an actual image or background including an image of the specific object obtained using the capturing camera (260-4) and a virtual image provided through at least one optical device (282, 284) are superimposed. The wearable device (200) can compensate for depth information (e.g., the distance between the wearable device (200) and an external object obtained through a depth sensor) using the image obtained through the capturing camera (260-4). The wearable device (200) can perform object recognition through an image acquired using a photographing camera (260-4). The wearable device (200) can perform a function of focusing on an object (or subject) in an image (e.g., auto focus) and / or an optical image stabilization (OIS) function (e.g., anti-shake function) using the photographing camera (260-4). The wearable device (200) can perform a pass-through function to display an image acquired through the photographing camera (260-4) by overlapping at least a portion of a screen representing a virtual space on at least one display (250). The photographing camera (260-4) can be disposed on a bridge (203) disposed between a first rim (201) and a second rim (202).

[0055] The gaze tracking camera (260-1) can implement more realistic augmented reality by tracking the gaze of a user wearing the wearable device (200) and thereby matching the user's gaze with visual information provided to at least one display (250). For example, when the wearable device (200) looks straight ahead, the wearable device (200) can naturally display environmental information related to the user's front at a location where the user is located on at least one display (250). The gaze tracking camera (260-1) can be configured to capture an image of the user's pupil to determine the user's gaze. For example, the gaze tracking camera (260-1) can receive gaze detection light reflected from the user's pupil and track the user's gaze based on the position and movement of the received gaze detection light. The gaze tracking camera (260-1) can be positioned at positions corresponding to the user's left and right eyes. For example, the gaze tracking camera (260-1) may be positioned within the first rim (201) and / or the second rim (202) to face the direction in which the user wearing the wearable device (200) is positioned.

[0056] The gesture recognition camera (260-2, 260-3) can recognize the movement of the user's entire body, such as the user's torso, hand, or face, or a part of the body, and thereby provide a specific event on a screen provided on at least one display (250). The gesture recognition camera (260-2, 260-3) can recognize the user's gesture (gesture recognition), obtain a signal corresponding to the gesture, and provide a display corresponding to the signal on at least one display (250). The processor can identify the signal corresponding to the gesture, and perform a designated function based on the identification. The gesture recognition camera (260-2, 260-3) can be used to perform simultaneous localization and mapping (SLAM) for 6 degrees of freedom pose (6 dof pose) and / or a spatial recognition function using a depth map. The processor can perform gesture recognition and / or object tracking functions using motion recognition cameras (260-2, 260-3). The motion recognition cameras (260-2, 260-3) can be positioned on the first rim (201) and / or the second rim (202).

[0057] The camera (260) included in the wearable device (200) is not limited to the above-described gaze tracking camera (260-1) and motion recognition cameras (260-2, 260-3). For example, the wearable device (200) can identify an external object included in the FoV using a camera positioned toward the user's FoV. The wearable device (200) can identify an external object based on a sensor for identifying the distance between the wearable device (200) and the external object, such as a depth sensor and / or a time of flight (ToF) sensor. The camera (260) positioned toward the FoV can support an autofocus function and / or an optical image stabilization (OIS) function. For example, the wearable device (200) may include a camera (260) (e.g., a face tracking (FT) camera) positioned toward the face to obtain an image including the face of a user wearing the wearable device (200).

[0058] Although not shown, the wearable device (200) may further include a light source (e.g., an LED) that emits light toward a subject (e.g., a user's eyes, face, and / or an external object within the FoV) being photographed using the camera (260). The light source may include an infrared wavelength LED. The light source may be disposed on at least one of the frame (295) and the hinge units (206, 207).

The plurality of battery modules (270) can be placed in each of the first temple (204) and the second temple (205). The battery module (270) can be placed at an end of the first temple (204) and / or the second temple (205).

[0060] The antenna module (275) can transmit signals or power to the outside of the wearable device (200), or receive signals or power from the outside. The antenna module (275) can be placed within the first temple (204) and / or the second temple (205). For example, the antenna module (275) can be placed close to one surface of the first temple (204) and / or the second temple (205).

[0061] The speaker (255) can output an audio signal to the outside of the wearable device (200). The audio output module may be referred to as a speaker. The speaker (255) may be positioned within the first temple (204) and / or the second temple (205) so as to be positioned adjacent to the ear of a user wearing the wearable device (200). For example, the speaker (255) may include a second speaker (255-2) positioned within the first temple (204) and thus positioned adjacent to the user's left ear, and a first speaker (255-1) positioned within the second temple (205) and thus positioned adjacent to the user's right ear.

[0062] The light-emitting module (not shown) may include at least one light-emitting element. The light-emitting module may emit light of a color corresponding to a specific state or emit light with an action corresponding to a specific state, in order to visually provide information regarding a specific state of the wearable device (200) to the user. For example, when the wearable device (200) requires charging, it may emit red light at a regular cycle. The light-emitting module may be disposed on the first rim (201) and / or the second rim (202).

[0063] Referring to FIG. 2B, the wearable device (200) may include a printed circuit board (PCB) (290).

The gyro sensor may measure an angular velocity of each of the designated three-dimensional axes (e.g., the x-axis, the y-axis, and the z-axis). At least one of the gravity sensor, the acceleration sensor, and the gyro sensor may be referred to as an inertial measurement unit (IMU). The wearable device (200) can identify a user's motion and / or gesture performed to execute or stop a specific function of the wearable device (200) based on the IMU.

[0065] Figures 3a and 3b illustrate the appearance of an exemplary wearable device.

[0066] The wearable device (200) of FIGS. 3A and 3B may be an example of the electronic device (101) of FIG. 1 and the wearable device (200) of FIGS. 2A and 2B. An example of the appearance of a first side (310) of a housing (300) of the wearable device (200) is illustrated in FIG. 3A, and an example of the appearance of a second side (320) of the housing (300) opposite to the first side (310) may be illustrated in FIG. 3B.

Although not shown, the wearable device (200) may further include a strap for fixing to a body part of a user, and / or one or more temples (e.g., the first temple (204) and / or the second temple (205) of FIGS. 2A and 2B). A first display (250-1) for outputting an image to a left eye among the user's two eyes, and a second display (250-2) for outputting an image to a right eye among the two eyes, may be disposed on the first surface (310).

The wearable device (200) may include cameras (260-5, 260-6) for photographing and / or recognizing the user's face. The cameras (260-5, 260-6) may be referred to as FT cameras. The wearable device (200) may control an avatar representing the user in a virtual space based on the motion of the user's face identified using the cameras (260-5, 260-6). For example, the wearable device (200) may change the texture and / or shape of a portion of an avatar (e.g., a portion of an avatar representing a human face) using information obtained by cameras (260-5, 260-6) (e.g., FT cameras) and representing the facial expression of a user wearing the wearable device (200).

[0069] Referring to FIG. 3B, a camera (e.g., cameras 260-7, 260-8, 260-9, 260-10, 260-11, 260-12)) and / or a sensor (e.g., a depth sensor 330) may be disposed on a second surface (320) opposite to the first surface (310) of FIG. 3A to obtain information related to the external environment of the wearable device (200). For example, the cameras (260-7, 260-8, 260-9, 260-10) may be disposed on the second surface (320) to recognize external objects. Cameras (260-7, 260-8, 260-9, 260-10) may be referenced to the motion recognition cameras (260-2, 260-3) of FIG. 2B.

[0070] For example, using cameras (260-11, 260-12), the wearable device (200) can obtain images and / or videos to be transmitted to each of the user's eyes. The camera (260-11) can be placed on the second face (320) of the wearable device (200) to obtain an image to be displayed through the second display (250-2) corresponding to the right eye among the two eyes. The camera (260-12) can be placed on the second face (320) of the wearable device (200) to obtain an image to be displayed through the first display (250-1) corresponding to the left eye among the two eyes.

Although not shown, a microphone may be disposed on the second face (320) of the wearable device (200) to obtain a sound output from an external object. The number of microphones may be one or more depending on the embodiment.

[0072] Figure 4 is a block diagram of an exemplary wearable device.

The processor (410), the memory (415), the display (420), the camera (425), the sensor (430), and the communication circuit (435) may be electrically and / or operably coupled with each other by an electronic component such as a communication bus (402). The type and / or number of hardware components included in the wearable device (200) are not limited to those illustrated in FIG. 4. For example, the wearable device (200) may include only some of the hardware components illustrated in FIG. 4. Elements (e.g., layers and / or modules) within the memory described below may be logically separated. However, it is not limited to this.

[0074] The processor (410) of the wearable device (200) may include a hardware component for processing data based on one or more instructions. The hardware component for processing data may include, for example, an arithmetic and logic unit (ALU), a field programmable gate array (FPGA), and / or a central processing unit (CPU). The number of processors (410) may be one or more. For example, the processor (410) may have a multi-core processor structure such as a dual core, a quad core, or a hexa core.

[0075] The memory (415) of the wearable device (200) may include a hardware component for storing data and / or instructions input and / or output to the processor (410).

The plurality of optical sensors included in the camera (425) may be arranged in the form of a two-dimensional array. The camera (425) may acquire electrical signals of each of the plurality of optical sensors substantially simultaneously, and generate two-dimensional frame data corresponding to light reaching the optical sensors of the two-dimensional array. For example, photographic data captured using the camera (425) may mean one (a) two-dimensional frame data acquired from the camera (425). For example, video data captured using the camera (425) may mean a sequence of a plurality of two-dimensional frame data acquired from the camera (425) according to a frame rate. The camera (425) may further include a flash light that is positioned toward the direction in which the camera (425) receives light and outputs light toward the direction.

[0078] The wearable device (200) may include, as an example, a plurality of cameras arranged facing different directions, such as a camera (425). Among the plurality of cameras, a first camera may be referred to as a motion recognition camera (e.g., motion recognition cameras 260-2 and 260-3 of FIG. 2B), and a second camera may be referred to as a gaze tracking camera (e.g., gaze tracking camera 260-1 of FIG. 2B). The wearable device (200) may identify a position, shape, and / or gesture of a hand using an image acquired using the first camera. The wearable device (200) may identify a direction of a gaze of a user wearing the wearable device (200) using an image acquired using the second camera. For example, the direction in which the first camera faces may be opposite to the direction in which the second camera faces.

[0079] The sensor (430) of the wearable device (200) can generate electrical information that can be processed by the processor (410) and / or memory (415) of the wearable device (200) from non-electronic information related to the wearable device (200). The information can be referred to as sensor data. The sensor (430) can include a global positioning system (GPS) sensor, an image sensor, an ambient light sensor, and / or a time-of-flight (ToF) sensor for detecting the geographic location of the wearable device (200), and an inertial measurement unit (IMU) for detecting the physical motion of the wearable device (200).

[0080] The communication circuit (435) of the wearable device (200) may include hardware components for supporting transmission and / or reception of electrical signals between the wearable device (200) and an external electronic device. The communication circuit (435) may include, for example, at least one of a modem, an antenna, and an optical / electronic (O / E) converter. The communication circuit (435) may support transmission and / or reception of electrical signals based on various types of protocols, such as Ethernet, a local area network (LAN), a wide area network (WAN), wireless fidelity (WiFi), Bluetooth, Bluetooth low energy (BLE), ZigBee, long term evolution (LTE), 5G NR (new radio), and / or 6G.

[0081] Within the memory (415) of the wearable device (200), one or more instructions (or commands) representing operations and / or actions to be performed on data by the processor (410) of the wearable device (200) may be stored. A set of one or more instructions may be referred to as firmware, an operating system, a process, a routine, a sub-routine, and / or an application. For example, the wearable device (200) and / or the processor (410) may perform at least one of the operations according to the embodiments described below when a set of a plurality of instructions distributed in the form of an operating system, firmware, a driver, and / or an application is executed. Hereinafter, the fact that an application is installed in a wearable device (200) may mean that one or more instructions provided in the form of an application are stored in a memory (415), and that the one or more applications are stored in a format executable by the processor (410) (e.g., a file having an extension specified by the operating system of the wearable device (200)). As an example, an application may include a program and / or a library related to a service provided to a user.

[0082] Referring to FIG. 4, programs installed in the wearable device (200) may be classified into one of different layers, including an application layer (440), a framework layer (450), and / or a hardware abstraction layer (HAL) (480), based on the target. For example, programs (e.g., modules or drivers) designed to target the hardware of the wearable device (200) (e.g., the display (420), the camera (425), and / or the sensor (430)) may be classified within the hardware abstraction layer (480). The framework layer (450) may be referred to as an XR framework layer in that it includes one or more programs for providing an XR (extended reality) service. For example, FIG. 4 illustrates layers being divided within the memory (415), the layers may be logically divided. However, the present invention is not limited thereto. Depending on the embodiment, the layers may be stored in a designated area within the memory (415).

[0083] For example, within the framework layer (450), programs designed to target at least one of the hardware abstraction layer (480) and / or the application layer (440) (e.g., a position tracker (471), a space recognizer (472), a gesture tracker (473), and / or an eye tracker (474), a face tracker (475)) may be classified. Programs classified within the framework layer (450) may provide an executable API (application programming interface) based on other programs.

[0084] For example, within the application layer (440), programs designed to target users controlling wearable devices (200) may be classified. Examples of programs classified into the application layer (440) include, but are not limited to, an XR (extended reality) system UI (user interface) and / or an XR application (442). For example, programs (e.g., software applications) classified into the application layer (440) may call an API (application programming interface) to cause execution of functions supported by programs classified into the framework layer (450).

[0085] For example, the wearable device (200) may display one or more visual objects on the display (420) for performing interaction with a user for using a virtual space based on the execution of the XR system UI (441). A visual object may refer to an object that can be deployed within a screen for transmitting and / or interacting with information, such as text, an image, an icon, a video, a button, a checkbox, a radio button, a text box, a slider, and / or a table. A visual object may be referred to as a visual guide, a virtual object, a visual element, a UI element, a view object, and / or a view element. The wearable device (200) may provide a service for controlling functions available within a virtual space to the user based on the execution of the XR system UI (441).

[0086] Referring to FIG. 4, a lightweight renderer (443) and / or an XR plug-in (444) are illustrated as being included within the XR system UI (441), but are not limited thereto. For example, the XR system UI (441) may cause execution of functions supported by the lightweight renderer (443) and / or the XR plug-in (444) included within the framework layer (450).

[0087] For example, the wearable device (200) may obtain resources (e.g., APIs, system processes, and / or libraries) used to define, create, and / or execute a rendering pipeline that allows partial changes based on the execution of a lightweight renderer (443). The lightweight renderer (443) may be referred to as a lightweight render pipeline in terms of defining a rendering pipeline that allows partial changes. The lightweight renderer (443) may include a renderer built prior to the execution of a software application (e.g., a prebuilt renderer). For example, the wearable device (200) may obtain resources (e.g., APIs, system processes, and / or libraries) used to define, create, and / or execute an entire rendering pipeline based on the execution of an XR plug-in (444). The XR plugin (444) may be referred to as an open XR native client from the perspective of defining (or configuring) the entire rendering pipeline.

[0088] For example, the wearable device (200) may display a screen representing at least a portion of a virtual space on the display (420) based on the execution of the XR application (442). The XR plug-in (444-1) included in the XR application (442) may be referenced by the XR plug-in (444) of the XR system UI (441). Descriptions of the XR plug-in (444-1) that overlap with the description of the XR plug-in (444) may be omitted. The wearable device (200) may cause the execution of the virtual space manager (451) based on the execution of the XR application (442).

[0089] The wearable device (200) can provide a virtual space service based on the execution of the virtual space manager (451). For example, the virtual space manager (451) can include a platform (e.g., an Android platform) for supporting the virtual space service. Based on the execution of the virtual space manager (451), the wearable device (200) can display the posture of a virtual object representing the user's posture rendered using data acquired through the sensor (430) on the display. The virtual space manager (451) can be referred to as a composition presentation manager (CPM).

[0090] For example, the virtual space manager (451) may include a runtime service (452). As an example, the runtime service (452) may be referred to as an OpenXR runtime module. The wearable device (200) may be used to provide at least one of a pose prediction function, a frame timing function, and / or a spatial input function to a user through the wearable device (200) based on the execution of the runtime service (452). As an example, the wearable device (200) may be used to perform rendering for a virtual space service to a user based on the execution of the runtime service (452). For example, an application (e.g., unity or an OpenXR native application) may be implemented based on the execution of the runtime service (452).

[0091] For example, the virtual space manager (451) may include a pass-through manager (453). Based on the execution of the pass-through manager (453), the wearable device (200) may display a screen representing a virtual space on the display (420), while another screen representing an actual space acquired through the camera (425) may be superimposed on at least a portion of the screen.

[0092] For example, the virtual space manager (451) may include an input manager (454). Based on the execution of the input manager (454), the wearable device (200) may identify data (e.g., sensor data) acquired by executing one or more programs included in the recognition service layer (470). The wearable device (200) may initiate execution of at least one of the functions of the wearable device (200) using the acquired data.

[0093] For example, the perception abstract layer (460) can be used for data exchange between the virtual space manager (451) and the perception service layer (470). From the perspective of being used for data exchange between the virtual space manager (451) and the perception service layer (470), the perception abstract layer (460) can be referred to as an interface. For example, the perception abstract layer (460) can be referenced as OpenPX. The perception abstract layer (460) can be used for a perception client and a perception service.

[0094] The recognition service layer (470) may include one or more programs for processing data acquired from a sensor (430) (or a camera (425)). The one or more programs may include at least one of a position tracker (471), a space recognizer (472), a gesture tracker (473), an eye tracker (474), and / or a face tracker (475). The type and / or number of the one or more programs included in the recognition service layer (470) are not limited to those illustrated in FIG. 4.

[0095] For example, the wearable device (200) can identify the pose of the wearable device (200) using the sensor (430) based on the execution of the position tracker (471). The wearable device (200) can identify the 6 degrees of freedom pose (6 dof pose) of the wearable device (200) using data acquired using the camera (425) and the IMU based on the execution of the position tracker (471). The position tracker (471) can be referred to as a head tracking (HeT) module.

[0096] For example, the wearable device (200) may be used to construct a three-dimensional virtual space around the wearable device (200) (or a user of the wearable device (200)) based on the execution of the space recognizer (472). The wearable device (200) may reconstruct the three-dimensional surroundings of the wearable device (200) using data acquired using the camera (425) based on the execution of the space recognizer (472). The wearable device (200) may identify at least one of a plane, a slope, and stairs based on the three-dimensionally reconstructed surroundings of the wearable device (200) based on the execution of the space recognizer (472). The space recognizer (472) may be referred to as a scene understanding (SU) module.

[0097] For example, the wearable device (200) may be used to identify (or recognize) a pose and / or gesture of a hand of a user of the wearable device (200) based on the execution of the gesture tracker (473). As an example, the wearable device (200) may identify a pose and / or gesture of a hand of a user using data acquired from a sensor (430) based on the execution of the gesture tracker (473). As an example, the wearable device (200) may identify a pose and / or gesture of a hand of a user based on data (or images) acquired using a camera based on the execution of the gesture tracker (473). The gesture tracker (473) may be referred to as a hand tracking (HaT) module and / or a gesture tracking module.

[0098] For example, the wearable device (200) can identify (or track) eye movements of a user of the wearable device (200) based on the execution of the gaze tracker (474). As an example, the wearable device (200) can identify eye movements of the user using data acquired from at least one sensor based on the execution of the gaze tracker (474). As an example, the wearable device (200) can identify eye movements of the user based on data acquired using a camera (e.g., the gaze tracking camera (260-1) of FIGS. 2A and 2B) and / or an infrared light emitting diode (IR LED) based on the execution of the gaze tracker (474). The gaze tracker (474) may be referred to as an eye tracking (ET) module and / or a gaze tracking module.

[0099] For example, the recognition service layer (470) of the wearable device (200) may further include a face tracker (475) for tracking the user's face. For example, the wearable device (200) may identify (or track) the movement of the user's face and / or the user's expression based on the execution of the face tracker (475). The wearable device (200) may estimate the user's expression based on the movement of the user's face based on the execution of the face tracker (475). As an example, the wearable device (200) may identify the movement of the user's face and / or the user's expression based on data (e.g., an image) acquired using a camera based on the execution of the face tracker (475).

[0100] FIG. 5A and FIG. 5B illustrate a portion of a housing of an exemplary wearable device.

[0101] Referring to FIGS. 5A and 5B, a wearable device (200) may include a housing (300) and connectors (510, 520).

[0102] The housing (300) may be supported by a part of the user's body (e.g., an ear or head) while the wearable device (200) is worn by the user. For example, the housing (300) may form or define the exterior of the wearable device (200). At least a portion of the housing (300) may come into contact with a part of the user's body while the wearable device (200) is worn by the user. For example, the housing (300) may form an internal space of the wearable device (200) to accommodate electronic components for driving the wearable device (200) and / or connecting it to an external electronic device (e.g., the electronic device (101) of FIG. 1). The internal space may be surrounded by an exterior surface of the wearable device (200) defined by the housing (300).

[0103] For example, the housing (300) may be a frame (295) that is supported by a part of the user's body (e.g., an ear) while the user wears the wearable device (200). Referring to FIGS. 2A and 2B together, the frame (295) may be coupled with at least one display (250) aligned to both eyes of the user while the user wears the wearable device (200), thereby supporting the at least one display (250). For example, referring to FIGS. 2A and 2B , the frame (295) may include a first temple (204) that is supported by the user's left ear and a second temple (205) that is supported by the user's right ear. For example, the frame (295) may include a nose pad (210) that is supported by the user's nose. However, the embodiments supported by the present disclosure are not limited thereto, and the housing (300) may include various structures supported by a part of the user's body while the wearable device (200), which may be referred to as a head mounted display (HMD) device, is worn on the user's head.

[0104] The first connector (510) and the second connector (520) may be coupled to the housing (300). For example, referring to FIGS. 2A and 2B together, the first connector (510) and the second connector (520) may be positioned on one of the temples (204, 205) of the wearable device (200). For example, the connectors (510, 520) may be positioned on the first temple (204). However, the embodiments supported by the present disclosure are not limited thereto. For example, the first connector (510) may be positioned on a first portion (300a) of the housing (300) that is spaced apart from a part of the user's body when the wearable device (200) is worn by the user. The second connector (520) may be arranged in the second portion (300b) of the housing (300) that comes into contact with a part of the user's body while the wearable device (200) is worn by the user. However, the embodiment is not limited thereto, and the connectors (510, 520) may be arranged in various ways within the housing (300) by being spaced apart from each other.

[0105] The first connector (510) may be a connector (e.g., a USB connector) for receiving data from an electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (200) or transmitting data from the electronic device (101). The second connector (520) different from (or separate from) the first connector (510) may be a connector for receiving power from an electronic device (e.g., the electronic device (101) of FIG. 1 or a battery pack) connected to the wearable device (200) or supplying power from the electronic device (101). The connectors (510, 520) may each be electrically connected to the electronic device (101) via one or more connection terminals (or connectors).

[0106] Since the first connector (510) for data transmission with the electronic device (101) and the second connector (520) for charging the wearable device (200) are separated from each other, the wearable device (200) may require wired connectors and / or terminals corresponding to each of the connectors (510, 520). The wearability of the wearable device (200) may be reduced by the wired connectors connected to each of the separated first connector (510) and second connector (520). In addition, the internal space of the housing (300) for electronic components other than the connectors (510, 520) may become narrow due to the mounting space within the housing (300) for the separated first connector (510) and second connector (520). The wearable device (200) may require a structure in which a connector (e.g., a first connector (510)) for data transmission with an electronic device (101) and a connector (e.g., a second connector (520)) for charging the wearable device (200) are integrated into a single connector (e.g., a connector (601) of FIG. 6A). The structure of the connector is described through an exemplary illustration of FIG. 6A and below.

[0107] Figures 6a and 6b illustrate a portion of a connector used in an exemplary wearable device.

[0108] Referring to FIGS. 6A and 6B, a connector (601) removably connected to a wearable device (e.g., the wearable device (200) of FIG. 2A) (or a connector of the wearable device (200) (e.g., the connector (701) of FIG. 7A)) may include a printed circuit board (650) and a plurality of conductive pins (600) spaced apart from each other.

[0109] The printed circuit board (650) may include a seating portion (655) on which a plurality of conductive pins (600) are disposed. For example, the plurality of conductive pins (600) may be coupled to the seating portion (655). The seating portion (655) of the printed circuit board (650) may define a section on which the plurality of conductive pins (600) are arranged. For example, the seating portion (655) of the printed circuit board (650) may have its boundary (or edge) defined by the outermost conductive pins among the array of the plurality of conductive pins (600), but this is merely an example described for convenience of illustration and description within the present disclosure, and thus the embodiment is not limited thereto.

[0110] The plurality of conductive pins (600) may include a plurality of power pins (610), a plurality of signal pins (620), and a plurality of ground pins (630). The plurality of power pins (610) may be configured to receive power from or supply power to an electronic device (101) connected to the connector (601). The plurality of signal pins (620) may be configured to receive data from or transmit data to the electronic device (101) connected to the connector (601). The plurality of ground pins (630) may be connected to a ground of the wearable device (200).

[0111] For example, the plurality of conductive pins (600) may be electrically connected to the plurality of conductive pads (e.g., the plurality of conductive pads (700) of FIG. 7b) of the wearable device (200) corresponding to each of the plurality of conductive pins (600) of another connector (e.g., the connector (701) of FIG. 7a) connected to the connector (601). The plurality of conductive pins (600) may be electrically connected to the plurality of conductive pads (700) of the other connector, thereby being connected to the wearable device (200).

[0112] For example, the plurality of power pins (610) may be configured to supply power to an electronic device (e.g., electronic device (101) of FIG. 1) connected to the connector (601) and / or another connector of the wearable device (200) (e.g., connector (701) of FIG. 7A), or to receive power from the external electronic device and / or another connector of the wearable device (200). For example, the plurality of power pins (610) may be configured to be electrically connected to a power line of the wearable device (200) while the connector (601) is connected to the wearable device (200). The power management integrated circuit (PMIC) of the wearable device (200) may be configured to charge a battery (e.g., a battery module (270) of FIG. 2B) of the wearable device (200) via a power line and the plurality of power pins (610), or to charge an electronic device (101) connected to the connector (601) via the power line and the plurality of power pins (610). By including the plurality of power pins (610), the connector (601) may function as a charging terminal. However, the embodiments supported in the present disclosure are not limited thereto.

[0113] For example, the plurality of signal pins (620) may be configured to transmit data to another connector (e.g., connector 701 of FIG. 7A) of an electronic device and / or a wearable device (200) connected to the connector (601), or to receive data from the external electronic device and / or the other connector. For example, the plurality of signal pins (620) may be configured to transmit data to a wearable device (200) including the other connector by being electrically connected to a plurality of signal pads (e.g., plurality of signal pads (720) of FIG. 7B) corresponding to each of the plurality of signal pins (620) and included in another connector connected to the connector (601). The plurality of signal pins (610) may receive data from the wearable device (200) via the plurality of signal pads (720). By including the plurality of signal pins (620), the connector (601) can function as a terminal (or USB terminal) for data transmission of the wearable device (200). The wearable device (200) is configured to be detachably connected to the connector (601) including both the plurality of power pins (610) and the plurality of signal pins (620), thereby improving the wearability of the wearable device (200) and reducing unnecessary space waste within the wearable device (200).

[0114] For example, the plurality of ground pins (630) can be electrically connected to the ground of the printed circuit board (650). For example, the plurality of ground pins (630) can be connected to a ground line of the connector (601). The plurality of ground pins (630) can discharge residual current flowing between the plurality of conductive pads (e.g., the plurality of conductive pads (700) in FIG. 7B) and the plurality of conductive pins (600) in another connector (e.g., the connector (701) in FIG. 7A) of the wearable device (200) and / or an electronic device) to the ground of the wearable device (200) when the connector (601) is connected to the other connector. By discharging the residual current to the ground, the plurality of ground pins (630) can reduce damage to the plurality of power pins (610) and / or the plurality of signal pins (620). However, the embodiments supported by the present disclosure are not limited thereto.

[0115] The connector (601) may have a structure including a plurality of power pins (610) and a plurality of signal pins (620), so that the repulsive force of the plurality of conductive pins (600) may increase while the connector (601) is connected to another connector (or an external electronic device). In addition, the plurality of power pins (610), the plurality of signal pins (620), and the plurality of ground pins (630) may require a structure to enhance the respective functions within the arrangement of the plurality of conductive pins (600). A structure of the connector (601) is described to reduce the repulsive force of the plurality of conductive pins (600) and enhance the respective functions of the plurality of power pins (610), the plurality of signal pins (620), and the plurality of ground pins (630).

[0116] Each diameter (R1) of the plurality of power pins (610) may be larger than each diameter (R2) of the plurality of signal pins (620). For example, the size of each of the plurality of power pins (610) may be larger than the size of each of the plurality of signal pins (620). For example, the area occupied by one power pin (e.g., the first power pin (611a)) of the mounting portions (655) may be larger than the area occupied by one signal pin (e.g., the first signal pin (621a)) of the mounting portions (655). For example, when the mounting portions (655) are viewed from above, the size of the area of ​​any one power pin of the plurality of power pins (610) may be larger than the size of the area of ​​any one signal pin of the plurality of signal pins (620). However, the embodiment supported by the present disclosure is not limited thereto, and the size of each of the plurality of signal pins (610) may be the largest among the plurality of conductive pins (600). For example, the diameter (R1) of each of the plurality of power pins (610) may be larger than the diameter (R3) of each of the plurality of ground pins (630). For example, the size of each of the plurality of power pins (610) may be larger than the size of each of the plurality of ground pins (630). However, the embodiment supported by the present disclosure is not limited thereto. The connector (601) includes a plurality of power pins (610) having a diameter (R1) larger than the diameter (R2) of each of the plurality of signal pins (620), thereby reducing resistance due to current flowing through the plurality of power pins (610) for power supply and reducing damage to the plurality of power pins (610).

[0117] A plurality of power pins (610) may be arranged in a central portion (655a) of a mounting portion (655) of a printed circuit board (650). Some of the plurality of signal pins (620) may be arranged in a peripheral portion (655b) surrounding the central portion (655a) of the mounting portion (655). The remaining portions of the plurality of signal pins (620) (e.g., signal pins (625a, 625b)) may be arranged in the central portion (655a) together with the plurality of power pins (610). For example, the central portion (655a) of the mounting portion (655) may be a portion that includes a central axis (C) of the mounting portion (655). For example, the peripheral portion (655b) may be a portion that includes the outermost conductive pins within an array of conductive pins (600). For example, the central portion (655a) may be a portion connected to and surrounded by the peripheral portion (655b). The boundary between the central portion (655a) and the peripheral portion (655b) may be determined by the arrangement of a plurality of conductive pins (600). However, the portions (655a, 655b) illustrated and described in the present disclosure are merely illustrative for the convenience of illustration and description, and thus the embodiment is not limited thereto.

[0118] For example, the plurality of power pins (610) may be positioned at a central portion within an array of the plurality of conductive pins (600). For example, the plurality of power pins (610) may include a first set of power pins (611) and a second set of power pins (612) disposed on a central portion (655a) of the mounting portion (655). The first set of power pins (611) may include a first power pin (611a) and a second power pin (611b) that are paired with each other. The second set of power pins (612) may include a third power pin (612a) and a fourth power pin (612b) that are paired with each other. For example, the first set of power pins (611) may be arranged parallel to the second set of power pins (612) on the center portion (655a) of the mounting portion (655). For example, referring to FIG. 6A, the first power pin (611a) and the second power pin (611b) may be arranged in the first direction (691) on the center portion (655a). The third power pin (612a) and the fourth power pin (612b) may be arranged in the first direction (691) on the center portion (655a). However, the embodiment supported by the present disclosure is not limited thereto, and the plurality of power pins (610) may be arranged at the center of the arrangement of the plurality of conductive pins (600), thereby optimizing or minimizing the size of the connector (601) for arranging the plurality of conductive pins (600) (or the size of the seating portion (655)).

[0119] For example, the first power pin (611a) may be a ground pin that provides a ground reference for the electrical circuit of the connector (601) or forms a return path for an electrical signal. For example, the second power pin (611b) may be a configuration channel (CC) pin that performs power negotiation via the USB power delivery (PD) protocol for charging the connector (601). The second power pin (611b), together with the first power pin (611a), may provide an appropriate current for charging and reduce overcurrent or overvoltage from occurring.

[0120] For example, the second set of power pins (612) may be paired VBUS pins for power supply. The second set of power pins (612) may support various voltages to a wearable device (200) connected to the connector (601) via the USB PD protocol. However, the embodiments supported in the present disclosure are not limited thereto.

[0121] The distances (d) between adjacent two conductive pins among the plurality of conductive pins (600) on the mounting portion (655) may be the same. Within the present disclosure, when an element is referred to as being "adjacent" to another element, it may mean that the other element is the element that has the closest vertical distance to the one element among the elements surrounding the one element. Furthermore, within the present disclosure, the distance between one conductive pin (or pad) and another conductive pin (or pad) may mean the distance from the center of the one conductive pin to the center of the other conductive pin. However, the embodiments supported within the present disclosure are not limited by this term.

[0122] For example, referring to FIG. 6a, the distance (d) between the fourth power pin (612b) and the first ground pin (631a) adjacent to the fourth power pin (612b) may correspond to the distance (d) between the fourth power pin (612b) and the third power pin (612a) adjacent to the fourth power pin (612b). For example, the distance (d) between the fourth power pin (612b) and the first ground pin (631a) adjacent to the fourth power pin (612b) may correspond to the distance (d) between the fourth power pin (612b) and the signal pin (625b) adjacent to the fourth power pin (612b). For example, the distance (d) between the fourth power pin (612b) and the first ground pin (631a) adjacent to the fourth power pin (612b) may correspond to the distance between the fourth power pin (612b) and the ground pin (633c) adjacent to the fourth power pin (612b). However, the embodiment supported by the present disclosure is not limited thereto. By configuring the distances (d) between two adjacent conductive pins among the plurality of conductive pins (600) on the mounting portion (655) to be the same, the connector (601) can optimize the arrangement of the plurality of conductive pins (600) within the connector (601).

[0123] The plurality of power pins (610) may be surrounded by a plurality of ground pins (630) and a plurality of signal pins (620). For example, referring to FIG. 6A, since the plurality of power pins (610) are disposed on the center portion (655a) of the mounting portion (655), they may be surrounded by ground pins (631, 632) and signal pins (621, 622, 623, 624, 626, 627) disposed on the periphery (655b) of the mounting portion (655). For example, referring to FIG. 6b, the plurality of power pins (610) may be surrounded by sets of ground pins (631, 632) and sets of signal pins (621, 622, 623, 624) disposed on the periphery (655b) of the mounting portion (655) because they are disposed on the mounting portion (655a). However, the embodiment supported by the present disclosure is not limited thereto, and the plurality of power pins (610) may be disposed at the center of the arrangement of the plurality of conductive pins (600), thereby optimizing or minimizing the size of the connector (601) for arranging the plurality of conductive pins (600) (or the size of the mounting portion (655)).

[0124] The plurality of ground pins (630) may be symmetrical with respect to the central axis (C) of the mounting portion (655). The central axis (C) of the mounting portion (655) may be the central axis of an array of the plurality of conductive pins (600) arranged on the mounting portion (655). The central axis (C) may be an imaginary axis passing through the center of gravity of the central portion (655a) of the mounting portion (655), but the embodiments supported in the present disclosure are not limited thereto.

[0125] For example, the plurality of ground pins (630) may include a first set of ground pins (631) and a second set of ground pins (632) arranged on a periphery (655b) of the mounting portion (655). The first set of ground pins (631) and the second set of ground pins (632) may be arranged to be symmetrical with respect to a central axis (C) of the mounting portion (655). For example, the first ground pin (631a) and the fourth ground pin (632a) may be symmetrical with respect to the central axis (C). For example, the second ground pin (631b) and the fifth ground pin (632b) may be symmetrical with respect to the central axis (C). For example, the third ground pin (631c) and the sixth ground pin (632c) may be symmetrical with respect to the central axis (C). However, the embodiments supported by the present disclosure are not limited thereto.

[0126] For example, referring to FIG. 6a, the plurality of ground pins (630) may include a third set of ground pins (633) and a fourth set of ground pins (634) disposed on a center portion (655a) of the mounting portion (655). The ground pins (633a, 633b, 633c) included in the third set of ground pins (633) may be symmetrical with respect to the central axis (C) with respect to the ground pins (634a, 634b, 634c) included in the fourth set of ground pins (634), respectively. For example, referring to FIG. 6b, the seventh ground pin (633a) and the eighth ground pin (634a) disposed on the center portion (655a) of the mounting portion (655) may be symmetrical with respect to the central axis (C). However, it should be noted that the above is merely exemplary and that the embodiments supported by the present disclosure are not limited to the names or symbols of the components. The connector (601) includes a plurality of ground pins (630) that are symmetrical to each other with respect to the central axis (C) and form pairs of ground pins, thereby stabilizing the arrangement structure of the plurality of conductive pins (600) and reducing damage to the plurality of power pins (610) and / or the plurality of signal pins (620).

[0127] The plurality of signal pins (620) may include sets of signal pins (621, 622, 623, 624, 625, 626, 627), each set including two signal pins that form a pair with each other. At least some sets of the sets of signal pins (621, 622, 623, 624, 625, 626, 627) may each be positioned between any two ground pins of the plurality of ground pins (630).

[0128] For example, the first set of signal pins (621) may be first Tx (transmit) pins for transmitting data to the wearable device (200). The second set of signal pins (622) may be first Rx (receive) pins, paired with the first set of signal pins (621), for receiving data from the wearable device (200). For example, the third set of signal pins (623) may be second Tx pins for transmitting data to the wearable device (200). The fourth set of signal pins (624) may be second Rx pins, paired with the third set of signal pins (623), for receiving data from the wearable device. However, the embodiments supported in the present disclosure are not limited thereto.

[0129] For example, the fifth set of signal pins (625) may be D+ and D- pins for high-speed USB data transmission with the wearable device (200). For example, the sixth set of signal pins (626) may be SBU (sideband use) pins for video signal transmission with the wearable device (200). For example, the seventh set of signal pins (627) may be CC (configuration channel) pins for detecting the directionality of the connector (601) and setting a communication protocol with the wearable device (200). However, the embodiments supported in the present disclosure are not limited thereto.

[0130] For example, at least some of the plurality of ground pins (630) may include ground pins (631, 632) arranged around the sets of signal pins (621, 622, 623, 624) configured to output or receive electrical signals when transmitting data to or receiving data from the wearable device (200), or shielding the sets of signal pins (621, 622, 623, 624). For example, the first set of signal pins (621) may be arranged between the first ground pin (631a) and the third ground pin (631c). The second set of signal pins (622) may be arranged between the second ground pin (631b) and the third ground pin (631c).

[0131] For example, the third set of signal pins (623) may be arranged between the fourth ground pin (632a) and the sixth ground pin (632c). The fourth set of signal pins (624) may be arranged between the fifth ground pin (632b) and the sixth ground pin (632c). However, the embodiments supported by the present disclosure are not limited thereto. The plurality of conductive pins (600) may include sets of signal pins (621, 622, 623, 624) arranged between any two ground pins among the plurality of ground pins (630), thereby reducing noise generated from the plurality of signal pins (620) and shielding the plurality of signal pins (620).

[0132] The sets of signal pins (621, 622, 623, 624) may share at least one ground pin with each other. For example, the first set of signal pins (621) may include a first signal pin (621a) and a second signal pin (621b) that are aligned in a first direction (691) and are paired with each other. Referring to FIG. 6A, the second set of signal pins (622) may include a third signal pin (622a) and a fourth signal pin (622b) that are aligned in a second direction (692) perpendicular to the first direction (691) and are paired with each other. Referring to FIG. 6b, the second set of signal pins (622) may include a third signal pin (622a) and a fourth signal pin (622b) that are arranged in a third direction (693) that is inclined with respect to the first direction (691) and are paired with each other.

[0133] For example, the plurality of ground pins (630) may include a first set of ground pins (631) that shields a first set of signal pins (621) and a second set of signal pins (622). The first set of ground pins (631) may include a first ground pin (631a) adjacent to a first signal pin (621a) of the first set of signal pins (621) that is distant from the second set of signal pins (622). The first set of ground pins (631) may include a second ground pin (631b) adjacent to a third signal pin (622a) of the second set of signal pins (622) that is distant from the first set of signal pins (621). The first set of ground pins (631) may include a second signal pin (621b) that is close to the second set of signal pins (622) among the first set of signal pins (621) and a third ground pin (631c) that is adjacent to it. The distance between the third ground pin (631c) and the second signal pin (621b) may correspond to the distance between the third ground pin (631c) and a fourth signal pin (622b) that is close to the first set of signal pins (621) among the second set of signal pins (622). The first set of signal pins (621) and the second set of signal pins (622) may share the third ground pin (631c) (or a ground line connected to the third ground pin (631c)). However, the embodiments supported by the present disclosure are not limited thereto.

[0134] For example, the plurality of ground pins (630) may include a second set of ground pins (632) that shields a third set of signal pins (623) and a fourth set of signal pins (624). The second set of ground pins (632) may include a fourth ground pin (632a) adjacent to a fifth signal pin (623a) of the third set of signal pins (623) that is distant from the fourth set of signal pins (624). The second set of ground pins (632) may include a fifth ground pin (632b) adjacent to a seventh signal pin (624a) of the fourth set of signal pins (624) that is distant from the third set of signal pins (623). The second set of ground pins (632) may include a sixth signal pin (623b) that is close to the fourth set of signal pins (624) among the third set of signal pins (623) and a sixth ground pin (632c) that is adjacent to the sixth signal pin (623b). The distance between the sixth ground pin (632c) and the sixth signal pin (623b) may correspond to the distance between the sixth ground pin (632c) and an eighth signal pin (624b) that is close to the third set of signal pins (623) among the fourth set of signal pins (624). The third set of signal pins (623) and the fourth set of signal pins (624) may share the sixth ground pin (632c) (or a ground line connected to the sixth ground pin (632c)). However, the embodiments supported by the present disclosure are not limited thereto. The plurality of ground pins (610) can optimize or minimize the size of the connector (601) (or the size of the seating portion (655)) for arranging the plurality of conductive pins (600) by including one or more ground pins shared between sets of signal pins (621, 622, 623, 624).

[0135] Each diameter (R3) of the plurality of ground pins (630) may correspond to each diameter (R2) of the plurality of signal pins (620). For example, each diameter (R3) of the plurality of ground pins (630) may be smaller than each diameter (R1) of the plurality of signal pins (610). Since each diameter (R3) of the plurality of ground pins (630) corresponds to each diameter (R2) of the plurality of signal pins (620), the plurality of conductive pins (600) may optimize the arrangement structure of the plurality of conductive pins (600) on the mounting portion (655). However, the embodiments supported in the present disclosure are not limited thereto.

[0136] The third set of ground pins (633) and the fourth set of ground pins (634) may be arranged at the center (655a) of the printed circuit board (650). The third set of ground pins (633) and the fourth set of ground pins (634) may be arranged symmetrically with respect to the center axis (C) of the printed circuit board (650), thereby being arranged at the center (655a) and may be used to shield the fifth set of signal pins (625) for high-speed signal transmission with the wearable device (200).

[0137] Referring to FIG. 6b, some (633b, 633c, 634b, 634c) of the third set of ground pins (633) and the fourth set of ground pins (634) arranged at the center (655a) from FIG. 6a may be omitted. By omitting some (633b, 633c, 634b, 634c) of the plurality of ground pins (630), the connector (601) can reduce the repulsive force of the plurality of conductive pins (600) and optimize or minimize the size of the connector (601) (or the size of the seating portion (655)) for arranging the plurality of conductive pins (600).

[0138] Referring to FIG. 6b, the distance (d1) between two most adjacent power pins among the plurality of power pins (610) may be greater than the distance (d2) between two most adjacent signal pins among the plurality of signal pins (620). For example, the distance between the first power pin (611a) and the second power pin (611b) among the power pins (611a, 611b, 612a, 612b) may be greater than the distance (d1) between the second power pin (611b) and the fourth power pin (612b). The distance between the fourth power pin (612b) and the third power pin (612a) may be greater than the distance (d1) between the fourth power pin (612b) and the second power pin (611b). The distance between the third power pin (612a) and the first power pin (611a) may be greater than the distance (d1) between the fourth power pin (612b) and the second power pin (611b). The distance between the two most adjacent power pins among the power pins (611a, 611b, 612a, 612b) may be determined as the distance (d1) between the second power pin (611b) and the fourth power pin (612b). For example, unlike FIG. 6a, the power pins (611a 611b, 612a, 612b) may be spaced apart from each other. For example, among the plurality of power pins (610), the distance (d1) between the second power pin (611b) and the fourth power pin (612b), which is the power pin closest to the second power pin (611b), may be greater than the distance (d1) between the fifth set of signal pins (625) that are arranged on the center (655b) of the mounting portion (655) and form a pair. However, the embodiments supported by the present disclosure are not limited thereto.The plurality of conductive pins (600) are configured so that the distance between the two most adjacent power pins (e.g., d1) among the plurality of power pins (610) is greater than the distance between the two most adjacent signal pins (e.g., d2) among the plurality of signal pins (620), thereby reducing resistance due to current flowing through the plurality of power pins (610) for power supply and reducing damage to conductive pins around the plurality of power pins (610).

[0139] The distance (d1) between two adjacent power pins among the plurality of power pins (610) may be greater than the diameter (R1) of each of the plurality of power pins (610). For example, the distance (d1) between two adjacent power pins among the plurality of power pins (610) may be greater than the diameter (R2) of each of the plurality of signal pins (620) and / or the diameter (R3) of each of the plurality of ground pins (630). For example, preferably, the distance (d1) between two adjacent power pins among the plurality of power pins (610) may correspond to about 1.5 times the diameter (R2) of each of the plurality of signal pins (620), but the embodiments supported in the present disclosure are not limited thereto. The plurality of conductive pins (600) are configured so that the distance (d1) between two adjacent power pins among the plurality of power pins (610) is greater than the diameter (R1) of each of the plurality of power pins (610), thereby reducing resistance due to current flowing through the plurality of power pins (610) for power supply and reducing damage to conductive pins around the plurality of power pins (610).

[0140] Referring to FIG. 6B, the plurality of conductive pins (600) may include sets of conductive pins, each including conductive pins arranged in a first direction (691). At least two sets of the sets of conductive pins may include different numbers of conductive pins.

[0141] For example, unlike FIG. 6A, the number of conductive pins included in each of the sets of conductive pins lined up in the first direction (691) may be different from each other. For example, referring to FIG. 6A, the number of conductive pins included in the sets of conductive pins lined up in the first direction (691) may be the same as six. Unlike FIG. 6A, referring to FIG. 6B, the number (five) of conductive pins (632c, 623b, 623a, 632a, 627a) lined up in the first direction (691) may be different from the number (six) of conductive pins (624a, 612a, 625a, 625b, 611a, 622a) lined up in the first direction (691). However, the embodiments supported in the present disclosure are not limited thereto. For example, unlike FIG. 6A, the plurality of conductive pins (600) may not be aligned in a second direction (692) that is perpendicular to the first direction (691). For example, the sets of conductive pins arranged in the second direction (692) may each include at least some conductive pins that are offset or misaligned with respect to the second direction (692). However, the embodiments supported by the present disclosure are not limited thereto.

[0142] The printed circuit board (650) may include an anti-reverse insertion structure (640) that guides the plurality of conductive pins (600) to be connected to the plurality of conductive pads (e.g., the plurality of conductive pads (700) of FIG. 7B) of the wearable device (200) (or the connector (701) of the wearable device (200) of FIG. 7A) corresponding to each of the plurality of conductive pins (600). For example, the anti-reverse insertion structure (640) may guide the connector (601) so that the connector (601) and the connector (701) of the wearable device (200) are aligned and connected. For example, the anti-reverse insertion structure (640) may include a recessed portion (641) and a tilting side (642) spaced apart from the recessed portion (641), but the embodiments supported in the present disclosure are not limited thereto. For example, referring also to FIG. 7A, the connector (701) of the wearable device (200) may have a anti-reverse insertion structure corresponding to the anti-reverse insertion structure (640) of the connector (601) that is detachably connected to the connector (701). The anti-reverse insertion structure of the connector (701) may have, for example, a protrusion that is slidably coupled to the recessed portion (641) of the connector (601) and / or a tilting side corresponding to the tilting side of the connector (601). However, the embodiments supported in the present disclosure are not limited thereto.

[0143] The number of the plurality of conductive pins (600) may be in the range of 24 to 30. For example, referring to FIGS. 6A and 6B, the number of the plurality of conductive pins (600) disposed on the mounting portion (655) of the printed circuit board (650) may vary by omitting at least some of the plurality of ground pins (630). Unlike the exemplary connector (601) illustrated and described in FIGS. 6A and 6B, the structure of the connector (601) for reducing the repulsive force of the plurality of conductive pins (600) and enhancing the function of each of the plurality of power pins (610), the plurality of signal pins (620), and the plurality of ground pins (630) is described with reference to the description of FIGS. 6A and 6B.

[0144] Figure 7a illustrates a connector connected to an exemplary wearable device. Figures 7b, 7c, and 7d illustrate connectors of an exemplary wearable device.

[0145] Referring to FIGS. 7A and 7B , a wearable device (200) may include a housing (300) that is supported by a part of a user's body when the wearable device (200) is worn by the user. The wearable device (200) may include a connector (701) that includes a printed circuit board (e.g., a printed circuit board (750) of FIG. 8A) disposed within the housing (300) and a plurality of conductive pads (700) that are disposed on a mounting portion (755) of the printed circuit board (750) and spaced apart from each other. The plurality of conductive pads (700) may include a plurality of power pads (710) that are configured to receive power from an electronic device (e.g., an electronic device (101) of FIG. 1) connected to the connector (701) or the connector (601) or to supply power to the electronic device (101) or the connector (601). The plurality of conductive pads (700) may include a plurality of signal pads (720) configured to receive data from or transmit data to the electronic device (101) connected to the connector (701). The connector (701) may include a plurality of ground pads (730) connected to the ground of the wearable device (200).

[0146] With reference to the exemplary illustrations and descriptions of FIGS. 6A and 6B, a connector (701) of a wearable device (200) of FIGS. 7A and 7B and a connector (601) configured to be connected to the connector (701) are exemplarily described. A plurality of conductive pads (700) arranged on the connector (701) of the wearable device (200) may be replaced with a plurality of conductive pins (600) exemplarily described in FIGS. 6A, 6B, and / or 7A, and conversely, a plurality of conductive pins (600) arranged on the connector (601) exemplarily described in FIG. 7A and below may be replaced with a plurality of conductive pads (700) exemplarily described in FIG. 7A and below. As illustrated, FIGS. 6A and 6B illustrate and describe a connector (601) detachably connected to a connector (701) of a wearable device (200), FIG. 7A illustrates and describes a connection between a connector (701) of a wearable device (200) and a connector (601), and FIGS. 7B to 7D illustrate and describe a connector (701) of a wearable device (200), but these are merely examples and it should be noted that the embodiments supported in the present disclosure are not limited thereto.

[0147] For example, the plurality of power pins (610) may form an array structure substantially the same as the plurality of power pads (710) so as to be connected to the plurality of power pads (710) corresponding to each of the plurality of power pins (610). For example, the plurality of signal pins (620) may form an array structure substantially the same as the plurality of signal pads (720) so as to be connected to the plurality of signal pads (720) corresponding to each of the plurality of signal pins (620). For example, the plurality of ground pins (630) may form an array structure substantially the same as the plurality of ground pads (730) so as to be connected to the plurality of ground pads (730) corresponding to each of the plurality of ground pins (630). The plurality of conductive pins (600) and / or the plurality of conductive pads (700) may have a structure substantially identical to the arrangement structure of the plurality of conductive pins (600) exemplarily illustrated and described in FIGS. 6A to 7D within the connectors (601, 701), respectively. It should be noted that this is merely exemplarily illustrated for convenience of illustration and description and is not intended to limit the embodiments supported by the present disclosure.

[0148] Referring to FIG. 7a, a plurality of conductive pins (600) may be arranged on a mounting portion (655) of a printed circuit board (650) of a connector (601). Referring also to FIG. 6b, the plurality of conductive pins (600) may further omit some (633a, 634a) of the plurality of ground pins (630). The plurality of conductive pins (600) may include an arrangement structure of the plurality of conductive pins (600) exemplarily illustrated and described in FIG. 6a and / or FIG. 6b.

[0149] For example, the diameter (R1) of each of the plurality of power pins (610) may be larger than the diameter (R2) of each of the plurality of signal pins (620). For example, the plurality of power pins (610) may be disposed in a central portion (655a) of a mounting portion (655) of a printed circuit board (650). Some of the plurality of signal pins (620) (e.g., sets of signal pins (621, 622, 623, 624)) may be disposed in a peripheral portion (655b) surrounding the central portion (655a) of the mounting portion (655). Some of the remaining signal pins (620) (e.g., sets of signal pins (625, 626, 627)) may be disposed in the central portion (655a) of the mounting portion (655). For example, the distances (d) between two adjacent conductive pins (600) among the plurality of conductive pins on the mounting portion (655) may be the same. For example, the plurality of power pins (610) may be surrounded by the plurality of ground pins (630) and the plurality of signal pins (620). For example, the plurality of ground pins (630) may be symmetrical with respect to the central axis (C) of the mounting portion (655).

[0150] For example, the plurality of signal pins (620) may include sets of signal pins (621, 622, 623, 624), each set including two signal pins that form a pair with each other. Each of the sets of signal pins (621, 622, 623, 624) may be positioned between any two ground pins of the plurality of ground pins (630). For example, the sets of signal pins (621, 622, 623, 624) may share at least one ground pin with each other.

[0151] For example, the diameter (R3) of each of the plurality of ground pins (630) may correspond to the diameter (R2) of each of the plurality of signal pins (620). For example, the distance (d1) between two most adjacent power pins among the plurality of power pins (610) may be greater than the distance (d2) between two most adjacent signal pins among the plurality of signal pins (620). For example, the distance (d1) between two most adjacent power pins among the plurality of power pins (610) may be greater than the diameter (R1) of each of the plurality of power pins (610). However, the embodiments supported by the present disclosure are not limited thereto, and the arrangement structure of the plurality of conductive pins (600) exemplarily illustrated and described in FIG. 7A may include the arrangement structure of the plurality of conductive pins (600) exemplarily illustrated and described in FIGS. 6A and 6B within a non-contradictory range.

[0152] The plurality of ground pins (630) may be arranged along the edge of the mounting portion (655) of the printed circuit board (650). For example, unlike FIG. 6B, the plurality of ground pins (630) may be arranged on a peripheral portion (655b) of the mounting portion (655) among the mounting portions (655). For example, when sequentially referring to FIGS. 6A, 6B, and 7A, at least some of the plurality of ground pins (630) (e.g., the third set of ground pins (633), the fourth set of ground pins (634)) may be omitted, thereby reducing the number of the plurality of conductive pins (600). By reducing the number of the plurality of conductive pins (600), the repulsive force between the connectors (601, 701) by the plurality of conductive pins (600) may be reduced.

[0153] Referring to FIG. 7b, the plurality of conductive pads (700) included in the connector (701) may have an arrangement structure substantially identical to the arrangement of the plurality of conductive pins (600) exemplarily illustrated and described in FIG. 7a. For example, the plurality of conductive pads (700) of FIG. 7b may include power pads (711a, 711b, 712a, 712b) corresponding to the power pins (611a, 611b, 612a, 612b) of FIG. 7a, respectively. For example, the plurality of conductive pads (700) may include signal pads (721a, 721b, 722a, 722b, 723a, 723b, 624a, 624b, 625a, 625b, 626a, 626b, 627a, 627b) corresponding to each of the signal pins (621a, 621b, 622a, 622b, 623a, 623b, 624a, 624b, 625a, 625b, 626a, 626b, 627a, 627b) of FIG. 7a. For example, the plurality of conductive pads (700) may include ground pads (731a, 731b, 731c, 732a, 732b, 732c) corresponding to the ground pins (631a, 631b, 631c, 632a, 632b, 632c) of FIG. 7A, respectively. However, the embodiments supported by the present disclosure are not limited thereto, and the connector (701) of the wearable device (200) may include a plurality of conductive pads (700) having a structure corresponding to the arrangement structure of the plurality of conductive pins (600) exemplarily illustrated and described in FIGS. 6A and 6B.

[0154] For example, referring to FIG. 7c, the conductive pads (700) may have a structure corresponding to the arrangement structure of the plurality of conductive pins (600) exemplarily illustrated and described in FIG. 6a. For example, referring to FIG. 7d, the conductive pads (700) may have a structure corresponding to the arrangement structure of the plurality of conductive pins (600) exemplarily illustrated and described in FIG. 6b by omitting the ground pads (733b, 733c, 734b, 734c) from FIG. 7c. However, the embodiments supported by the present disclosure are not limited thereto.

[0155] The connector (701) may include a cover (760) including a plurality of through holes (765) respectively aligned on the plurality of conductive pads (700) so that the plurality of conductive pads (700) are visible from the outside of the wearable device (200). For example, the cover (760) may be coupled to the housing (300) to cover components of the connector (701) inside the housing (300), such as a printed circuit board (750). The number of the plurality of through holes (765) formed in the cover (760) may correspond to the number of the plurality of conductive pads (700) and / or the plurality of conductive pins (600) penetrating the plurality of through holes (765). For example, the diameter of each of the plurality of through-holes (765) may be larger than the diameter (R1) of each of the plurality of power pins (610) among the plurality of conductive pins (600) of the connector (601). For example, the size (e.g., diameter) of each of the plurality of conductive pads (700) may correspond to the size of each of the plurality of conductive pins (600) corresponding to each of the plurality of conductive pads (700). For example, the size (e.g., diameter) of each of the plurality of through-holes (765) may correspond to the size (e.g., diameter) of each of the plurality of conductive pins configured to pass through each of the plurality of through-holes (765), or may be larger than the size of each of the plurality of conductive pins. However, the embodiments supported in the present disclosure are not limited thereto.

[0156] Figure 8a illustrates a connector connected to an exemplary wearable device. Figures 8b and 8c illustrate the internal structure of the connector of the exemplary wearable device.

[0157] Referring to FIGS. 8A, 8B, and 8C, a wearable device (200) may include a housing (300) that is supported by a part of a user's body when the wearable device (200) is worn by the user. The wearable device (200) may include a connector (701) that includes a printed circuit board (750) disposed within the housing (300) and a plurality of conductive pads (700) that are disposed on a mounting portion (755) of the printed circuit board (750) and are spaced apart from each other. The plurality of conductive pads (700) may include a plurality of power pads (e.g., a plurality of power pads (710) of FIG. 7B) that are configured to receive power from an electronic device (e.g., an electronic device (101) of FIG. 1) connected to the connector (701) or to supply power to the electronic device (101). The plurality of conductive pads (700) may include a plurality of signal pads (e.g., a plurality of signal pads (720) of FIG. 7B) configured to receive data from or transmit data to the electronic device (101) connected to the connector (701). The connector (701) may include a plurality of ground pads (e.g., a plurality of ground pads (730) of FIG. 7B) connected to the ground of the wearable device (200). However, the embodiment is not limited thereto, and the plurality of conductive pads (700) of the wearable device (200) exemplarily illustrated and described in FIGS. 8A to 8C may include an arrangement structure of the plurality of conductive pins (600) and the plurality of conductive pads (700) exemplarily illustrated and described in FIGS. 7A and 7B. Hereinafter, redundant descriptions of components having the same reference numerals as those described in FIGS. 7a and 7b may be omitted.Although not shown in FIGS. 8A to 8C, the arrangement structure of the plurality of conductive pins (600) may include the structure of FIG. 6A or FIG. 6B, and the arrangement structure of the plurality of conductive pads (700) may include the structure of FIG. 7C or FIG. 7D.

[0158] A connector (701) of a wearable device (200) may include a first support plate (820) attached to a mounting portion (755) of a printed circuit board (750) of the connector (701) and configured to support the plurality of conductive pads (700). Another connector (601) connected to the connector (701) and including a plurality of conductive pins (600) may include a second support plate (830) attached to a mounting portion (655) of a printed circuit board (650) of the other connector (601) and configured to support the plurality of conductive pins (600). For example, the first support plate (820) can reduce the detachment of the plurality of conductive pads (700) pressed by the plurality of conductive pins (600) from the mounting portion (755) by fixing and / or attaching the plurality of conductive pads (700) onto the first support plate (820). For example, the second support plate (830) can reduce the detachment of the plurality of conductive pins (600) pressed by the plurality of conductive pads (700) from the mounting portion (655) by passing the plurality of conductive pins (600). However, the embodiments supported in the present disclosure are not limited thereto.

[0159] A printed circuit board (750) may define a first surface (750a) facing a plurality of through holes (765) of a cover (760) and on which a plurality of conductive pads (700) are arranged, and a second surface (750b) opposite to the first surface (750a). The connector (701) may further include at least one electronic component (801) arranged on the second surface (750b), and a shield can (810) arranged on the second surface (750b) and surrounding the at least one electronic component (801). For example, the electronic component (801) may be spaced from the plurality of conductive pads (700) by the printed circuit board (750). For example, the electronic component (801) may be an integrated circuit for driving the connector (701). The electronic component (801) may be a USB driving circuit, but the embodiments supported by the present disclosure are not limited thereto. For example, the shield can (810) may shield the electronic component (801) by surrounding the electronic component (801). For example, the plurality of conductive pads (700) may be elastically deformed by being pressed by the plurality of conductive pins (600). In order to provide a space in which the plurality of conductive pins (600) are pressed, additional space may be required under the cover of the connector (701) covering the printed circuit board (750) (e.g., the cover (760) of FIG. 7B). The electronic component (801) and the shield can (810) surrounding the electronic component (801) can be placed on a second surface (750b) opposite to the first surface (750a) of the printed circuit board (750) on which the conductive pads (700) are placed, thereby providing additional space under the cover (760) for the conductive pads (700) to be pressed.

[0160] For example, a plurality of conductive pins (600) can be inserted through a plurality of through-holes of the cover (760) (e.g., a plurality of through-holes (765) of FIG. 7b). When a shield can (810) (or an electronic component (801)) having a height (h3) is placed on a second side (750b) of a printed circuit board (750), the length of the plurality of conductive pads (700) pressed by the plurality of conductive pins (600) on a first side (750a) opposite to the second side (750b) can be provided as a height (h1) protruding from a first support plate (820) for supporting the plurality of conductive pads (700) and a height (h2) passing through the first support plate (820). However, the embodiments supported in the present disclosure are not limited thereto.

The wearable device may include a printed circuit board (e.g., the printed circuit board (650) of FIG. 6A) disposed within the housing, and a connector including a plurality of conductive pins (e.g., the plurality of conductive pins (600) of FIG. 6A) disposed on a mounting portion (e.g., the mounting portion (655) of FIG. 6A) of the printed circuit board and spaced apart from each other. The plurality of conductive pins may include a plurality of power pins (e.g., the plurality of power pins (610) of FIG. 6A) configured to receive power from an external electronic device connected to the connector or to supply power to the external electronic device.

The plurality of conductive pins may include a plurality of ground pins (e.g., a plurality of ground pins (630) of FIG. 6A) connected to a ground of the wearable device. A diameter of each of the plurality of power pins (e.g., R1 of FIG. 6A) may be larger than a diameter of each of the plurality of signal pins (e.g., R2 of FIG. 6A).

[0162] For example, the plurality of power pins may be arranged in a center portion of the mounting portion (e.g., center portion 655a of FIG. 6A). The plurality of signal pins may be arranged in a peripheral portion surrounding the center portion of the mounting portion (e.g., peripheral portion 655b of FIG. 6A).

[0163] For example, the distance between two adjacent power pins among the plurality of power pins (e.g., d1 in FIG. 6A) may be greater than the distance between two adjacent signal pins among the plurality of signal pins (e.g., d2 in FIG. 6A).

[0164] For example, the distance between two adjacent signal pins among the plurality of signal pins may be greater than the diameter of each of the plurality of power pins.

[0165] For example, the distances between two adjacent conductive pins among the plurality of conductive pins on the mounting portion (e.g., d in FIG. 6a) may be the same as each other.

[0168] For example, the plurality of signal pins may include sets of signal pins, each of which includes two signal pins that form a pair (e.g., sets of signal pins (621, 622, 623, 624) of FIG. 6A). Each of the sets of signal pins may be positioned between any two ground pins of the plurality of ground pins.

[0169] For example, the sets of signal pins may include a first set of signal pins arranged in a first direction (e.g., the first set of signal pins (621) of FIG. 6A), and a second set of signal pins arranged in a second direction different from the first direction (e.g., the second set of signal pins (622) of FIG. 6A). The plurality of ground pins may include a first ground pin (e.g., a first ground pin (631a) of FIG. 6A) adjacent to a first signal pin (e.g., a first signal pin (621a) of FIG. 6A) among the signal pins of the first set that is far from the signal pins of the second set, a second ground pin (e.g., a second ground pin (631b) of FIG. 6A) adjacent to a second signal pin (e.g., a third signal pin (622a) of FIG. 6A) among the signal pins of the second set that is far from the signal pins of the first set, and a third ground pin (e.g., a third ground pin (631c) of FIG. 6A) adjacent to a third signal pin (e.g., a second signal pin (621b) of FIG. 6A) among the signal pins of the first set that is close to the signal pins of the second set. The distance between the third ground pin and the third signal pin may correspond to the distance between the third ground pin and a fourth signal pin (e.g., the fourth signal pin (622b) of FIG. 6A) that is close to the signal pins of the first set of signal pins among the second set of signal pins.

[0170] For example, the plurality of ground pins may be arranged along the edge of the mounting portion.

[0171] For example, the diameter of each of the plurality of ground pins (e.g., R3 in FIG. 6A) may correspond to the diameter of each of the plurality of signal pins.

[0172] For example, the connector may further include a cover (e.g., cover (760) of FIG. 7B) including a plurality of through holes (e.g., a plurality of through holes (765) of FIG. 7B) respectively aligned over the plurality of conductive pins so that the plurality of conductive pins are visible from the outside of the wearable device.

[0173] For example, the printed circuit board may define a first surface (e.g., a first surface (650a) of FIG. 8B) facing the plurality of through holes and on which the plurality of conductive pins are arranged, and a second surface (e.g., a second surface (650b) of FIG. 8B) opposite the first surface. The connector may further include at least one electronic component (e.g., at least one electronic component (801) of FIG. 8B) arranged on the second surface, and a shield can (e.g., a shield can (810) of FIG. 8B) arranged on the second surface and surrounding the at least one electronic component.

[0174] For example, the plurality of conductive pins may each include sets of conductive pins, each set including conductive pins arranged in a third direction. At least two sets of the sets of conductive pins may include different numbers of conductive pins.

[0175] For example, the number of the plurality of conductive pins may be in the range of 24 to 30.

[0177] For example, the plurality of power pins may be arranged at the center of the mounting portion. The plurality of signal pins may be arranged at the periphery surrounding the center of the mounting portion.

[0178] For example, the distance between two adjacent power pins among the plurality of power pins may be greater than the distance between two adjacent signal pins among the plurality of signal pins.
