Description

Electronic device including a button assembly

[0001] Embodiments of the present disclosure relate to electronic devices, for example, electronic devices including a button assembly.

[0002] Thanks to remarkable advancements in information and communication technology and semiconductor technology, the proliferation and use of various electronic devices is rapidly increasing. In particular, recent electronic devices are being developed to enable portability and communication.

[0003] Electronic devices can refer to devices that perform specific functions based on the programs installed on them, such as home appliances, electronic notebooks, portable multimedia players, mobile communication terminals, tablet PCs, audio / video devices, desktop / laptop computers, and car navigation systems. For example, these electronic devices can output stored information as audio or video. As the integration of electronic devices increases and ultra-high-speed, high-capacity wireless communications become widespread, a single electronic device, such as a mobile communication terminal, can now be equipped with a variety of functions. For example, in addition to communication functions, entertainment functions such as games, multimedia functions such as music / video playback, communication and security functions such as mobile banking, and functions such as schedule management and electronic wallets are being integrated into a single electronic device. These electronic devices are becoming smaller and more portable for users.

[0004] As electronic devices become smaller, the need for optimal internal space increases.

[0005] An electronic device may include components that can be mounted internally, such as a button for inputting external signals. When physical pressure is applied to the button, it can be retracted into the electronic device and transmit external signals to the device's internal processor. In one embodiment, the button may be based on a dome switch, which takes up a relatively large amount of mounting space.

[0006] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art in connection with the present disclosure.

The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0047] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), or output sound through an audio output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0048] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status.

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 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).

[0056] 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.

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.

[0061] FIG. 2 is a front perspective view of an electronic device according to one embodiment. FIG. 3 is a rear perspective view of the electronic device according to one embodiment.

[0062] In the detailed description below, the longitudinal direction of the electronic device (101) may be defined as the 'Y-axis direction', the width direction as the 'X-axis direction', and / or the height direction (thickness direction) as the 'Z-axis direction'. In the detailed description below, references to the longitudinal direction, the width direction, and / or the height direction (or thickness direction) may indicate the longitudinal direction, the width direction, and / or the height direction (or thickness direction) of the electronic device. According to one embodiment, since the button assembly may be arranged on the side of the electronic device (101), when referring to the longitudinal direction, the width direction, and / or the height direction (or thickness direction) with respect to the button assembly, it may be different from the longitudinal direction, the width direction, and / or the height direction (or thickness direction) of the electronic device. For example, the height direction with respect to the button assembly may be the 'X-axis direction'. According to an embodiment, the height direction with respect to the button assembly may be the 'Y-axis direction'. In some embodiments, with respect to the direction in which a component is oriented, 'yin / yang (- / +)' may be mentioned together with the rectangular coordinate system illustrated in the drawing. For example, referring to FIG. 2, the front of the electronic device (101) or the housing (201) may be defined as a 'surface facing the -Z-axis direction', and the rear may be defined as a 'surface facing the +Z-axis direction'. According to one embodiment of the present disclosure, in an electronic device including a button assembly, the arrangement relationship in the height direction, that is, the reference for up / down, may be based on the +X-axis direction / -X-axis direction. That is, when a component is arranged on another component, it may mean that a component is arranged on the +X-axis direction with respect to the other component, and when a component is arranged under another component, it may mean that a component is arranged on the -X-axis direction with respect to the other component.Meanwhile, it should be noted that even if a component is positioned above or below another component, this does not mean that the entire component is positioned above or below all of the components of the other component. For example, a part of a component may be positioned above a part of another component, but another part of the component may be positioned below a part of the other component. In one embodiment, when a component is said to be "viewed from above," this may mean looking at the component in the -X-axis direction from a position spaced apart from the component by a predetermined height. In one embodiment, when a component is said to be facing "a certain direction," it may be understood to include not only a case where the component is facing "substantially the same direction as the certain direction," but also a case where the component is facing "a direction substantially parallel to the certain direction." It should be noted that when a component is said to be overlapped (or stacked) with another component in the following description, the description of the arrangement relationship in the height direction described above may be applied. In describing directions, if 'yin / yang (- / +)' is not indicated, it can be interpreted to include both + and - directions unless otherwise defined. For example, 'Z-axis direction' can be interpreted to include both +Z and -Z directions. Similarly, 'X-axis direction' can be interpreted to include both +X and -X directions, and 'Y-axis direction' can be interpreted to include both +Y and -Y directions. However, in the XYZ spatial coordinate system depicted in the drawing, if 'yin / yang (- / +)' is not indicated for an axis, the axis can be interpreted to point in the + direction.In describing a direction, facing one of the three axes of the orthogonal coordinate system may include facing in a direction parallel to the axis. Hereinafter, in the description to be described later, the 'first direction' may mean the +Y-axis direction. And the 'second direction' may mean the -Y-axis direction. And the 'third direction' may mean the -X-axis. And the 'fourth direction' may mean the +X-axis. It should be noted that the above description is based on the orthogonal coordinate system described in the drawings for the sake of brevity of description, and the description of such directions or components does not limit the various embodiments of the present disclosure.

[0063] Referring to FIGS. 2 and 3 , an electronic device (101) according to one embodiment may include a housing (201) including a front surface (201A), a back surface (201B), and a side surface (201C) surrounding a space between the front surface (201A) and the back surface (201B). In one embodiment (not shown), the housing (201) may refer to a structure forming a portion of the front surface (201A) of FIG. 2 , the back surface (201B) of FIG. 3 , and the side surface (201C). According to one embodiment, at least a portion of the front surface (201A) may be formed by a substantially transparent front plate (202) (e.g., a glass plate including various coating layers, or a polymer plate). The back surface (201B) may be formed by a back plate (211). The rear plate (211) may be formed of, for example, glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the foregoing materials. The side surface (201C) may be formed by a side bezel structure (or “side member”) (212) that is coupled to the front plate (202) and the rear plate (211) and includes metal and / or polymer. In some embodiments, the front plate (202) and the side bezel structure (212) may be formed as one body and include the same material. Alternatively, the rear plate (211) and the side bezel structure (212) may be formed as one body and include the same material (e.g., a metal material such as glass or aluminum, or a ceramic).

[0080] FIG. 4 is a drawing illustrating a button assembly according to one embodiment of the present disclosure. FIG. 5 is a drawing illustrating a feedback curve when a click sensation is provided according to a deformation of a switch when a button assembly is input according to one embodiment of the present disclosure.

[0081] According to one embodiment of the present disclosure, an electronic device (101) may include a button assembly (220). The button assembly (220) of the present disclosure may correspond to the key input device (216, 217) illustrated in FIG. 2.

[0082] Referring to FIG. 4, the button assembly (220) may include a body (221). The body (221) may include a button top (2211) that exposes at least a portion of the button assembly (220) to the outside of the electronic device, and a flange (2212) that prevents the button assembly (220) from being pulled out of the electronic device.

[0083] The button assembly (220) may include a substrate portion (223). The substrate portion (223) may have an elongated shape so as to be electrically connected to other electronic components within the electronic device (100). In addition, the substrate portion (223) may be formed flexibly. According to one embodiment, the substrate portion (223) may include a first substrate (2231), a second substrate (2232), and a connection substrate (2233) connecting the first substrate (2231) and the second substrate (2232). A dome switch module (225) may be mounted on one surface of the substrate portion (223).

[0084] The button assembly (220) may include a sensor (222) for sensing a user's input to the button assembly (220). The sensor (222) may be applied in various ways, such as an ultrasonic sensor (e.g., a fingerprint sensor), an optical sensor, a pressure sensor, a resistance sensor, or a capacitance sensor. According to one embodiment, the button assembly (220) may include an adhesive layer (224) for stacking the substrates included in the substrate portion (223) on each other.

[0085] In the embodiment of FIG. 4 described above, the dome switch module (225) may be configured to contact the switch electrode disposed relatively inside the housing (201) relative to the button assembly (220). Referring to FIGS. 4 and 5 together, when a user presses the button assembly (220), the dome portion of the dome switch module (225) provides a click sensation to the user through a pressing and / or returning deformation, thereby allowing the user to recognize that the button assembly (220) has been pressed. In this way, the haptic feedback by the dome switch module may be achieved, for example, through a physical deformation of the dome portion formed of a stainless steel material. Therefore, the button assembly (220) using only the dome switch module (225) and the electronic device (101) including it only feed back an input corresponding to the magnitude of the force (F) applied to the dome portion over time (T), as illustrated in FIG. 5, and thus can provide only a simple tactile sensation to the user.

[0086] FIG. 6 is a diagram illustrating the internal appearance of an electronic device according to an embodiment of the present disclosure. FIG. 7 is a diagram illustrating the intensity of vibration provided to an electronic device when a vibration motor vibrates according to an embodiment of the present disclosure. FIG. 8 is a diagram illustrating the intensity of vibration provided to an electronic device when a vibration motor vibrates according to an embodiment of the present disclosure. FIG. 9 is a graph illustrating various patterns of haptic feedback that can be provided through a button assembly according to an embodiment of the present disclosure.

[0087] Referring to FIG. 6, an electronic device (101) (e.g., the electronic device (101) of FIG. 1 or FIG. 2) may include a housing (201) (e.g., a side bezel structure (212)), a bracket (230), at least one printed circuit board (or board assembly) (240, 250), at least one electronic component, and a battery (270). When including at least one printed circuit board (240, 250), the electronic device (101) may include at least one flexible printed circuit board (250) to electrically connect the printed circuit board(s) and / or the electronic component(s). In one embodiment, the electronic device (101) may omit at least one of the components or additionally include another component (e.g., a connector hole (213)). At least one of the components of the electronic device (101) may be identical or similar to at least one of the components of the electronic device (101) of FIGS. 1 to 3, and any overlapping description will be omitted below.

[0088] The electronic device (101) may include a vibration motor (260) as an electronic component (e.g., a haptic module (179) of FIG. 1). The vibration motor (260) may provide an alarm function to the electronic device (101) or a haptic function according to an input by the user through the button assembly (220). When the vibration motor (260) operates, the user may sense vibration throughout the electronic device (101), as illustrated in FIGS. 7 and 8 . The embodiments of FIGS. 7 and 8 may divide the intensity of vibration generated in the electronic device (101) into regions, and a higher density of points may indicate a higher intensity of vibration. Referring to FIGS. 6 and 7 together, when the vibration motor (260) is arranged at the lower end of one side of the electronic device (101), the vibration may be concentrated generally at a corner portion of the electronic device (101). In contrast, when the position of the vibration motor (260) is arranged as in Fig. 8, the area where vibration is felt in the electronic device (101) can be changed. In this way, by using the vibration motor (260), vibration can be transmitted to the entire palm or fingers.

[0089] However, since the haptic feedback for the user using the vibration motor (260) utilizes the vibration from the vibration motor (260) located further away when the user presses the button assembly (220), there may be limitations in providing precise and diverse haptic feedback to the user. As illustrated in FIGS. 7 and 8, the position where the vibration motor (260) is placed and the area where the vibration is strongest may not correspond due to various factors such as the arrangement and / or materials of the electronic device (101) and / or various components included within the electronic device (101).

[0090] In the present disclosure, for example, by applying input sensing technology to a button assembly (220) (e.g., key input devices (216, 217)), when a user presses the button assembly (220), localized haptic feedback can be provided, and for example, more precise and diverse click sensations can be provided, as in graphs (a), (b), and (c) illustrated in FIG. 9. Graphs (a), (b), and (c) of FIG. 9 represent voltage and time graphs applied to the button assembly (220). For example, (a) of FIG. 9 may represent providing a temporary feedback vibration to the user through the button assembly (220), (b) of FIG. 9 may represent providing an irregular feedback vibration to the user through the button assembly (220), and (c) of FIG. 9 may represent providing a periodic feedback vibration to the user through the button assembly (220). Examples of providing feedback vibration to a user through the button assembly (220) are not limited to the above-described embodiment and may vary. According to one embodiment, feedback to the user through the button assembly (220) may be provided as part of providing various user experiences (UX) through the electronic device (101). The button assembly (220) may include a sensor (222) in the button assembly (220) to apply the input sensing technology.

[0091] Hereinafter, button assemblies according to various embodiments of the present disclosure will be described in detail with reference to the embodiments of FIGS. 10 to 24. The components described with reference to FIGS. 10 to 24 may be partially or entirely identical to the components described with reference to FIGS. 1 to 9.

A user may input a signal to the button assembly (300) by touching and / or manipulating the first surface (311) of the body portion (310). When a user touches the body part (310), the body part (310) may be configured to move in a first direction (e.g., +Y-axis direction) or a second direction (e.g., -Y-axis direction) to provide haptic feedback to the user. In FIG. 10, a first surface (311) of the body part (310) is illustrated as having a stepped shape with respect to one surface of the housing (201), but an embodiment may also be included in which the first surface (311) of the body part (310) is formed in substantially the same plane as one surface of the housing (201). According to an embodiment, a window (not shown) may be arranged outside the housing (201) and the body part (310) so that the body part (310) is only visually exposed to the outside of the electronic device (101), and a user may indirectly perform a touch input to the body part (310) through the window.

[0095] The button assembly (300) may include support members (3130, 3140). The support members (3130, 3140) may be disposed between the body portion (310) and the housing (201). According to one embodiment, the support members (3130, 3140) may include a third surface (313) forming one end of the body portion (310) and a fourth surface (314) forming the other end.

For example, the support members (3130, 3140) may include a rubber material. When pressure is applied to the body portion (310), a portion of the support member (3130, 3140) may be deformed. According to one embodiment, the support member (3130, 3140) may support at least a portion of the second surface (312) of the body portion (310). Here, the support member (3130, 3140) may be referred to as a “buffering member” in that it has a function of alleviating the impact applied to the housing (201) and / or the button assembly (300) when the body portion (310) of the button assembly (300) moves. The support member (3130, 3140) may be referred to as an “elastic member” in that it has a function of providing an elastic repulsive force to restore the body portion (310) of the button assembly (300) to its original state before moving after moving.

[0096] The button assembly (300) may include a first magnetic member (3122). According to one embodiment, the button assembly (300) may include a first magnetic member (3122) disposed on one surface of the body portion (310). Here, the magnetic member may be referred to as a 'magnetic substance'. For example, a magnet or a permanent magnet may be an example of the magnetic substance, but is not limited thereto. For example, any magnetic substance that maintains polarity (e.g., maintains opposite polarities (3122a, 3122b)) may be included in the magnetic member.

[0097] According to one embodiment, the first magnetic member (3122) may be disposed on one side of the first protrusion (3121) protruding from the body portion (310) toward the interior space of the housing (201). At this time, the direction of the magnetic field formed by the polarity of the first magnetic member (3122) may be substantially perpendicular to the second side (312) of the body portion (310).

[0098] The button assembly (300) may include a coil portion (320). According to one embodiment, the coil portion (320) may face the first magnetic member (3122). According to one embodiment, the coil portion (320) may be configured to be fixedly disposed on another structure (e.g., the bracket (230) of FIG. 6) disposed inside the housing (201). The coil portion (320) may include a coil wound a plurality of times. For example, the coil portion (320) may include a solenoid coil, which is a long, cylindrical coil in which a conductor is uniformly wound.

[0099] According to one embodiment, the coil portion (320) may include a first yoke (321) disposed at one end. The first yoke (321) may be configured to face the first magnetic member (3122). The first yoke (321) may serve to concentrate a magnetic field generated when a current is applied to the coil portion (320). According to another embodiment, the coil portion (320) may include a second yoke (322) disposed at the other end. The second yoke (322) may be disposed on the opposite side of the first yoke (321). The second yoke (322), like the first yoke (321), may also serve to concentrate a magnetic field generated when a current is applied to the coil portion (320). For example, the first yoke (321) and / or the second yoke (322) may be formed using a magnetic material including an iron family metal such as iron, steel, stainless steel, nickel, cobalt, a rare earth element, and / or other magnetizable material. In addition, if it has a polarity due to a magnetic field formed around the first yoke (321), it may be included in the magnetic material constituting the first yoke (321), and if it has a polarity due to a magnetic field formed around the second yoke (322), it may be included in the magnetic material constituting the second yoke (322). If a magnetic field is not formed around the first yoke (321), the first yoke (321) may not have a polarity, and if a magnetic field is not formed around the second yoke (322), the second yoke (322) may also not have a polarity.

[0100] The button assembly (300) may include a driver IC (340). According to one embodiment, the button assembly (300) may include a driver IC (340) that is electrically connected to the coil portion (320) and controls the flow of current flowing in the coil portion (320) to generate an attractive force and / or a repulsive force between the first magnetic member (3122) and the coil portion (320). Here, the driver IC (340) is described as a component included in the button assembly (300), but depending on the embodiment, it may be a component included in the button assembly (300), or may be disposed on a printed circuit board external to the button assembly (300) and within the electronic device (101). The driver IC (340) may be referred to as a 'processor (e.g., the processor (120) of FIG. 1)'. Alternatively, the driving circuit (340) may correspond to an auxiliary processor (e.g., an auxiliary processor (123) of FIG. 1) provided separately from a main processor (e.g., a main processor (121) of FIG. 1) disposed within the electronic device (101). In addition, the electronic device (101) may further include a memory (e.g., a memory (130) of FIG. 1) that stores instructions executed by the processor to cause the electronic device to perform haptic feedback.

[0101] According to one embodiment, the button assembly (300) may include a connecting coil (330) that electrically connects the coil portion (320) and the driving circuit (340). According to one embodiment, the connecting coil (330) may be integrally connected to a coil included in the coil portion (320). The connecting coils (330) may be provided as a pair between the coil portion (320) and the driving circuit (340). In addition, the driving circuit (340) may apply current to the coil portion (320) through the pair of connecting coils (330), and may change the direction of the magnetic field formed in the coil portion (320) by changing the direction in which the current flows (e.g., clockwise → counterclockwise, or counterclockwise → clockwise).

[0102] When current flows through the coil portion (320), a magnetic field can be formed in one direction at the center of the coil portion (320) by Ampere's right-handed screw rule. According to one embodiment, when a first magnetic member (3122) is disposed on one surface of the body portion (310) (e.g., a surface perpendicular to the second surface (312) of the body portion (310) in the first protrusion) and one end of the coil portion (320) is disposed to face the first magnetic member (3122), the magnetic field formed by the coil portion (320) and the magnetic field formed by the first magnetic member (3122) can interact with each other. According to the above interaction, an attractive or repulsive force may be generated between the first magnetic member (3122) and the coil portion (320), which may cause the body portion (310) of the button assembly (300) to move.

[0103] When a user touches the button assembly (300) and an input is applied to the button assembly (300), if the input corresponds to an input for executing a preset algorithm and / or is an input exceeding a preset value (e.g., refer to a lookup table), a signal for a haptic operation may be transmitted to the driving circuit (340). At this time, the type of the signal for the haptic operation may be various and may be stored in the memory. The driving circuit (340) may control the magnitude of the current flowing in the coil unit (320) and / or the direction of application of the current according to the signal for the haptic operation to move the body unit (310) of the button assembly (300). The user may feel various vibration patterns according to the movement of the body unit (310), and in this way, the user may be provided with various haptic feedbacks. As the body part (310) of the button assembly (300) of the electronic device (101) moves under the control of the driving circuit (340), it can provide the user with various vibration patterns, such as those shown in (a), (b), and (c) of FIG. 9 or other vibration patterns not shown in FIG. 9.

[0104] Referring to FIGS. 11 and 12, a button assembly (300) according to one embodiment may be arranged such that a second pole (3122b) (e.g., an N pole) of a first magnetic member (3122) is in contact with one surface of a body portion (310) (e.g., a surface perpendicular to a second surface (312) of the body portion (310) at the first protrusion) and a first pole (3122a) (e.g., an S pole) faces in the opposite direction to the second pole (3122b). At this time, as illustrated in FIG. 11, when a current flows in a counterclockwise direction from the connecting coil (330) to the coil portion (320), and has a polarity (e.g., N pole) different from the first pole (3122a) (e.g., S pole) of the first magnetic member (3122) at one end of the coil portion (320), an attractive force may be generated between the first magnetic member (3122) and the coil portion (320). As illustrated in FIG. 12, when a current flows in a clockwise direction from the connecting coil (330) to the coil portion (320), and has a polarity (e.g., S pole) identical to the first pole (3122a) (e.g., S pole) of the first magnetic member (3122) at one end of the coil portion (320), a repulsive force may be generated between the first magnetic member (3122) and the coil portion (320). If the coil portion (320) is fixed to the inside of the housing (201) (e.g., the bracket (230) of FIG. 6), the body portion (310) of the button assembly (300) moves in the first direction (S1) when a force is applied as shown in FIG. 11, and the body portion (310) of the button assembly (300) moves in the second direction (S2) when a repulsive force is applied as shown in FIG. 12. Meanwhile, the arrangement of polarities shown in FIGS. 11 and 12 may vary depending on the embodiment.

[0105] Fig. 13 is a drawing showing a button assembly according to one embodiment of the present disclosure. Fig. 14 is a drawing showing a body part moving in a first direction when current is applied to a coil part according to one embodiment of the present disclosure. Fig. 15 is a drawing showing a body part moving in a second direction when current is applied to a coil part according to one embodiment of the present disclosure.

[0106] The embodiments of FIGS. 13 to 15 may further include, compared to the embodiments of FIGS. 10 to 12, a second protrusion (3123) and a second magnetic member (3124) disposed on the second protrusion (3123). In describing the embodiments of FIGS. 13 to 15, a description thereof may be omitted to the extent that it overlaps with the configuration included in the embodiments of FIGS. 10 to 12.

[0107] In the embodiments of FIGS. 13 to 15, the button assembly (300) may include a first magnetic member (3122) and a second magnetic member (3124). According to one embodiment, the button assembly (300) may include a first magnetic member (3122) disposed on one surface of the body portion (310) and a second magnetic member (3124) disposed on the other surface of the body portion (310). For example, the first magnetic member (3122) may be disposed on a surface perpendicular to the second surface (312) of the body portion (310) at the first protrusion (3121), and the second magnetic member (3124) may be disposed on a surface perpendicular to the second surface (312) of the body portion (310) at the second protrusion (3123). Here, both the first magnetic member (3122) and the second magnetic member (3124) may be referred to as a 'magnetic substance'. For example, a permanent magnet may be an example of a magnetic substance. The first magnetic member (3122) and the second magnetic member (3124) may be arranged to face each other. Here, the fact that the first magnetic member (3122) and the second magnetic member (3124) face each other may mean that the same polarities are arranged to face each other. Referring to FIG. 13, a button assembly (300) according to one embodiment may be arranged such that a second pole (3122b) (e.g., an N pole) of a first magnetic member (3122) is in contact with a first protrusion (3121), and a first pole (3122a) (e.g., an S pole) faces in an opposite direction to the second pole (3122b), and a fourth pole (3124b) (e.g., an N pole) of a second magnetic member (3124) is in contact with a second protrusion (3123), and a third pole (3124a) (e.g., an S pole) faces in an opposite direction to the fourth pole (3124b). Of course, the arrangement of the polarities illustrated herein may vary depending on the embodiment.

[0108] According to one embodiment, the coil portion (320) may have one end facing the first magnetic member (3122) and the other end facing the second magnetic member (3124). According to another embodiment, the coil portion (320) may include a first yoke (321) disposed at the one end and a second yoke (322) disposed at the other end. The first yoke (321) may be configured to face the first magnetic member (3122) and the second yoke (322) may be configured to face the second magnetic member (3124).

[0109] When current flows in the coil unit (320), if an attractive force (or repulsive force) is generated between the first magnetic member (3122) and the coil unit (320), a repulsive force (or attractive force) may be generated between the second magnetic member (3124) and the coil unit (320). The driving circuit (340) applies a current to the coil unit (320) through a pair of connecting coils (330), and by changing the direction in which the current flows (e.g., clockwise → counterclockwise, or counterclockwise → clockwise), the direction of the magnetic field formed in the coil unit (320) may be changed. When the direction of the magnetic field formed in the coil unit (320) is changed, a repulsive force (or attractive force) is generated between the first magnetic member (3122) and the coil unit (320), and an attractive force (or repulsive force) may be generated between the second magnetic member (3124) and the coil unit (320).

[0110] Referring to FIGS. 14 and 15, a button assembly (300) according to one embodiment is configured such that a second pole (3122b) (e.g., an N pole) of a first magnetic member (3122) is in contact with one surface of a body portion (310) (e.g., a surface perpendicular to a second surface (312) of the body portion (310) from the first protrusion), and a first pole (3122a) (e.g., an S pole) is arranged in a state opposite to the second pole (3122b), and a fourth pole (3124b) (e.g., an N pole) of a second magnetic member (3124) is in contact with another surface of the body portion (310) (e.g., a surface perpendicular to a second surface (312) of the body portion (310) from the second protrusion), and a third pole (3124a) (e.g., an S pole) is in contact with the fourth It can be arranged in a state facing in the opposite direction to the pole (3124b). At this time, as illustrated in FIG. 14, when a current flows in and out of the coil (330) in a counterclockwise direction to the coil portion (320), one end of the coil portion (320) has a different polarity (e.g., N pole) from the first pole (3122a) (e.g., S pole) of the first magnetic member (3122), so that an attractive force is generated between the first magnetic member (3122) and the coil portion (320), and the other end of the coil portion (320) has the same polarity (e.g., S pole) as the third pole (3124a) (e.g., S pole) of the second magnetic member (3124), so that a repulsive force can be generated between the second magnetic member (3124) and the coil portion (320). As illustrated in FIG. 15, when a current flows in a clockwise direction from the connection coil (330) to the coil portion (320), if one end of the coil portion (320) has the same polarity (e.g., S pole) as the first pole (3122a) (e.g., S pole) of the first magnetic member (3122), a repulsive force is generated between the first magnetic member (3122) and the coil portion (320), and if the other end of the coil portion (320) has a different polarity (e.g., N pole) than the third pole (3124a) (e.g., S pole) of the second magnetic member (3124), an attractive force may be generated between the second magnetic member (3124) and the coil portion (320).When the coil portion (320) is fixed to the inside of the housing (201) (e.g., the bracket (230) of FIG. 6), the body portion (310) of the button assembly (300) moves in the first direction (S1) as shown in FIG. 14, and the body portion (310) of the button assembly (300) moves in the second direction (S2) as shown in FIG. 15. Meanwhile, the polarity arrangement shown in FIGS. 14 and 15 may vary depending on the embodiment.

[0111] In the button assembly (300) according to the embodiments of FIGS. 13 to 15, the magnetic attractive force and repulsive force are applied simultaneously to both ends, including one end and the other end, so that, unlike the button assembly (300) according to the embodiments of FIGS. 10 to 12 in which the magnetic attractive force or repulsive force is applied only to one end, the button assembly can be moved by receiving a greater force (e.g., twice the force).

[0112] Fig. 16 is a drawing showing a button assembly according to one embodiment of the present disclosure. Fig. 17 is a drawing showing a body part moving in a first direction when current is applied to a coil part according to one embodiment of the present disclosure.

[0113] Referring to FIG. 16, the electronic device (101) may include a button assembly (400) (e.g., the key input devices (216, 217) of FIG. 2, the button assembly (220) of FIG. 4, and the button assembly (300) of FIGS. 10 to 15). The button assembly (400) may be disposed in the housing (201). According to one embodiment, the button assembly (400) may be disposed in the side bezel structure (212) of the housing (201). For example, the button assembly (400) may be visually exposed to the outside of the housing (201) through the side bezel structure (212). The side bezel structure (212) may be referred to as a “side portion.” Here, the button assembly (400) may be referred to as a “key input device.” Additionally, the button assembly (400) may be referred to as an “input device.” Additionally, the button assembly (400) may be referred to as a "haptic device" in that it can provide the user with a sense of touch, movement, and force.

For example, the support members (4130, 4140) may include a rubber material. When pressure is applied to the body portion (410), a portion of the support member (4130, 4140) may be deformed. Here, the support member (4130, 4140) may be referred to as a “buffering member” in that it has a function of alleviating the impact applied to the housing (201) and / or the button assembly (400) when the body portion (410) of the button assembly (400) moves. The support member (4130, 4140) may be referred to as an “elastic member” in that it has a function of providing an elastic repulsive force to restore the body portion (410) of the button assembly (400) to its original state before moving after moving.

[0116] The button assembly (400) may include a first magnetic member (4122). According to one embodiment, the button assembly (400) may include a first magnetic member (4122) disposed on one surface of the body portion (410). Here, the magnetic member may be referred to as a 'magnetic material'.

The connecting coils (430) may be provided as a pair between the first coil portion (420a) and the driving circuit (440), and may be provided as a pair between the second coil portion (420b) and the driving circuit (440). The driving circuit (440) can change the direction of the magnetic field formed in the first coil portion (420a) by applying current to the first coil portion (420a) and the connecting coil (430) through a pair of connecting coils (430), and by changing the direction in which the current flows (e.g., clockwise → counterclockwise, or counterclockwise → clockwise). In addition, the driving circuit (440) can change the direction of the magnetic field formed in the second coil portion (420b) by applying current to the second coil portion (420b) and the connecting coil (430) through a pair of connecting coils (430), and by changing the direction in which the current flows (e.g., clockwise → counterclockwise, or counterclockwise → clockwise).

[0125] As illustrated in FIG. 17, when a current flows from the connection coil (430) to the first coil portion (420a), and a polarity (e.g., a N pole or a S pole) is expressed at one end of the first coil portion (420a), an attractive force may be generated between the first magnetic member (4122) and the first coil portion (420a). At this time, the current applied from the connection coil (430) to the first coil portion (420a) may flow in a clockwise or counterclockwise direction, and accordingly, an attractive force may be generated between the first magnetic member (4122) and the first coil portion (420a) regardless of the polarity formed at one end of the first coil portion (420a). As illustrated in FIG. 18, when a current flows from the connection coil (430) to the second coil portion (420b), and a polarity (e.g., a N pole or a S pole) is expressed at one end of the second coil portion (420b), an attractive force may be generated between the second magnetic member (4124) and the second coil portion (420b). At this time, the current applied from the connection coil (430) to the second coil portion (420b) may flow in a clockwise or counterclockwise direction, and accordingly, an attractive force may be generated between the second magnetic member (4124) and the second coil portion (420b) regardless of the polarity formed at one end of the second coil portion (420b). According to the embodiment illustrated in FIG. 17, the body part (410) of the button assembly (400) moves in the first direction (S1), and according to the embodiment illustrated in FIG. 18, the body part (410) of the button assembly (400) moves in the second direction (S2).

[0128] According to one embodiment, the first magnetic member (4122) and the second magnetic member (4124) may be fixedly disposed inside the housing (e.g., bracket (230) of FIG. 6). Although FIGS. 19 to 21 illustrate that the first magnetic member (4122) and the second magnetic member (4124) are connected to each other, in some embodiments, the first magnetic member (4122) and the second magnetic member (4124) may be fixedly disposed inside the housing (e.g., bracket (230) of FIG. 6) without being connected to each other.

[0129] A first coil portion (420a) may be arranged on one side of a first protrusion (4121) protruding from the body portion (410) toward the internal space of the housing (201). A second coil portion (420b) may be arranged on one side of a second protrusion (4123) protruding from the body portion (410) toward the internal space of the housing (201).

[0130] When current flows through the first coil part (420a) or the second coil part (420b), a magnetic field can be formed in one direction at the center of the coil part (420) independently of each other in the first coil part (420a) and the second coil part (420b) according to Ampere's right-hand rule. According to one embodiment, when a first coil portion (420a) is disposed on one side of the body portion (410) (e.g., a side perpendicular to the second side (412) of the body portion (410) from the first protrusion) and one end of the first magnetic member (4122) is disposed to face the first coil portion (420a), an attractive force may be generated between the first magnetic member (4122) and the first coil portion (420a) due to a magnetic field formed by the first coil portion (420a), thereby allowing the body portion (410) of the button assembly (400) to move. In one embodiment, when a second coil portion (420b) is disposed on the other surface of the body portion (410) (e.g., a surface perpendicular to the second surface (412) of the body portion (410) in the second protrusion) and one end of the second magnetic member (4124) is disposed to face the second coil portion (420b), an attractive force may be generated between the second magnetic member (4124) and the second coil portion (420b) due to a magnetic field formed by the second coil portion (420b), thereby allowing the body portion (410) of the button assembly (400) to move.

[0131] As illustrated in FIG. 20, when a current flows from the connection coil (430) to the first coil portion (420a), and a polarity (e.g., a N pole or a S pole) is expressed at one end of the first coil portion (420a), an attractive force may be generated between the first magnetic member (4122) and the first coil portion (420a). At this time, the current applied from the connection coil (430) to the first coil portion (420a) may flow in a clockwise or counterclockwise direction, and accordingly, an attractive force may be generated between the first magnetic member (4122) and the first coil portion (420a) regardless of the polarity formed at one end of the first coil portion (420a). As illustrated in FIG. 21, when a current flows from the connection coil (430) to the second coil portion (420b), and a polarity (e.g., a N pole or a S pole) is expressed at one end of the second coil portion (420b), an attractive force may be generated between the second magnetic member (4124) and the second coil portion (420b). At this time, the current applied from the connection coil (430) to the second coil portion (420b) may flow in a clockwise or counterclockwise direction, and accordingly, an attractive force may be generated between the second magnetic member (4124) and the second coil portion (420b) regardless of the polarity formed at one end of the second coil portion (420b). According to the embodiment illustrated in FIG. 20, the body part (410) of the button assembly (400) moves in the first direction (S1), and according to the embodiment illustrated in FIG. 21, the body part (410) of the button assembly (400) moves in the second direction (S2).

The button assembly (500) may be disposed in the housing (201). According to one embodiment, the button assembly (500) may be disposed in a side bezel structure (212) of the housing (201). For example, the button assembly (500) may be visually exposed to the outside of the housing (201) through the side bezel structure (212). The side bezel structure (212) may be referred to as a “side portion.” Here, the button assembly (500) may be referred to as a “key input device.” Additionally, the button assembly (500) may be referred to as an "input device." Furthermore, the button assembly (500) may be referred to as a "haptic device" in that it can provide the user with a sense of touch, movement, and force. Furthermore, the button assembly (500) may be referred to as a "feedback device" in that it provides the user with a click sensation corresponding to an input.

[0138] The button assembly (500) may include a body portion (510). The body portion (510) may be visually exposed to the outside of the housing (201).

[0139] The button assembly (500) may include support members (5130, 5140). The support members (5130, 5140) may be disposed between the body portion (510) and the housing (201). According to one embodiment, the support members (5130, 5140) may include a third surface (513) forming one end of the body portion (510) and a fourth surface (514) forming the other end. According to one embodiment, the support members (5130, 5140) may include a first support member (5130) supporting the third surface (513) of the body portion (510) and a second support member (5140) supporting the fourth surface (514) of the body portion (510). For example, the support members (5130, 5140) may include a rubber material. When pressure is applied to the body portion (510), a portion of the support member (5130, 5140) may be deformed. According to one embodiment, the support member (5130, 5140) may support at least a portion of the second surface (512) of the body portion (510). Here, the support member (5130, 5140) may be referred to as a “buffering member” in that it has a function of alleviating the impact applied to the housing (201) and / or the button assembly (500) when the body portion (510) of the button assembly (500) moves. The support member (5130, 5140) may be referred to as an “elastic member” in that it has a function of providing an elastic repulsive force to restore the body portion (510) of the button assembly (500) to its original state before moving after moving.

[0140] The button assembly (500) may include a first magnetic member (5125). According to one embodiment, the button assembly (500) may include a first magnetic member (5125) disposed on one surface of the body portion (510). Here, the magnetic member may be referred to as a 'magnetic substance'. For example, a magnet or a permanent magnet may be an example of the magnetic substance. In addition, any magnetic substance that maintains polarity in a certain state (e.g., maintains opposite polarities (5125a, 5125b)) may be included in the magnetic member.

[0141] According to one embodiment, the first magnetic member (5125) may be disposed on a second surface (512) of the body portion (510) facing the interior space of the housing (201). At this time, the direction of the magnetic field formed by the polarity of the first magnetic member (5125) may be substantially parallel to the direction in which the second surface (512) of the body portion (510) faces.

[0142] The button assembly (500) may include a coil portion (520). In one embodiment, the coil portion (520) may face the first magnetic member (5125). In one embodiment, the coil portion (520) may be configured to be fixedly disposed on another structure (e.g., bracket (230, 550)) disposed inside the housing (201). The coil portion (520) may include a coil wound a plurality of times. For example, the coil portion (520) may include a solenoid coil, which is a long, cylindrical coil in which a wire is uniformly wound.

[0143] According to one embodiment, the coil portion (520) may include a first yoke (521) disposed at one end. The first yoke (521) may be configured to face the first magnetic member (5125). The first yoke (521) may serve to concentrate a magnetic field generated when a current is applied to the coil portion (520). According to another embodiment, the coil portion (520) may include a second yoke (522) disposed at the other end. The second yoke (522) may be disposed on the opposite side of the first yoke (521). The second yoke (522), like the first yoke (521), may also serve to concentrate a magnetic field generated when a current is applied to the coil portion (520). The description of the first yoke (521) and the second yoke (522) may be applied to the description of the first yoke (321, 421) and the second yoke (322, 422) discussed in other embodiments above.

[0144] The button assembly (500) may include a driving circuit (540). According to one embodiment, the button assembly (500) may include a driving circuit (540) that is electrically connected to the coil portion (520) and controls the flow of current flowing in the coil portion (520) to generate an attractive force and / or a repulsive force between the first magnetic member (5125) and the coil portion (520). According to one embodiment, the button assembly (500) may include a connecting coil (530) that electrically connects the coil portion (520) and the driving circuit (540). According to one embodiment, the connecting coil (530) may be integrally connected with a coil included in the coil portion (520). The connecting coils (530) may be provided as a pair between the coil portion (520) and the driving circuit (540). The description of the driving circuit (540) and the connecting coil (530) may be applied in accordance with the description of the driving circuit (340, 440) and the connecting coil (330, 430) discussed in other embodiments above.

[0145] When current flows through the coil portion (520), a magnetic field can be formed in one direction at the center of the coil portion (520) by Ampere's right-handed screw rule. According to one embodiment, when a first magnetic member (5125) is disposed on one surface (e.g., the second surface (512)) of the body portion (510) and one end of the coil portion (520) is disposed to face the first magnetic member (5125), the magnetic field formed by the coil portion (520) and the magnetic field formed by the first magnetic member (5125) can interact with each other. According to the above interaction, an attractive or repulsive force may be generated between the first magnetic member (5125) and the coil portion (520), which may cause the body portion (510) of the button assembly (500) to move in a direction perpendicular to the housing of the electronic device (e.g., in the X-axis direction). In addition, the description of the button assemblies (300, 400) discussed in other embodiments above may be applied to an operation of providing haptic feedback to a user using the button assembly (500).

[0146] The embodiment of Fig. 24 may further include, compared to the embodiment of Fig. 23, the second bracket (550) and the second magnetic member (5510) arranged on the second bracket (550). In describing the embodiment of Fig. 24, the description thereof may be omitted to the extent that it overlaps with the configuration included in the embodiment of Fig. 23.

[0147] The second bracket (550) is a configuration arranged in the internal space of the housing (201), and according to one embodiment, it may be a configuration distinct from the bracket (230) (hereinafter referred to as the 'first bracket (230)'), but according to another embodiment, it may be a configuration formed integrally with the first bracket (230).

[0148] In the embodiment of FIG. 24, the button assembly (500) may include a first magnetic member (5125) and a second magnetic member (5510). According to one embodiment, the button assembly (500) may include a first magnetic member (5125) disposed on one surface (e.g., the second surface (512)) of the body portion (510) and a second magnetic member (5510) disposed on one surface (551) of the second bracket (550).

[0149] For example, the first magnetic member (5125) may be disposed on the second surface (512) of the body portion (510), and the second magnetic member (5510) may be disposed on the surface (551) of the second bracket (550) that faces the second surface (512) of the body portion (510). Here, both the first magnetic member (5125) and the second magnetic member (5510) may be referred to as a 'magnetic substance'. For example, a permanent magnet may be an example of the magnetic substance. The first magnetic member (5125) and the second magnetic member (5510) may be disposed to face each other. Here, the fact that the first magnetic member (5125) and the second magnetic member (5510) face each other may mean that they are disposed to face each other with the same polarity. Referring to FIG. 24, a button assembly (500) according to one embodiment may be arranged such that a second pole (5125b) (e.g., an N pole) of a first magnetic member (5125) is in contact with a second surface (512) of a body portion (510), and a first pole (5125a) (e.g., an S pole) faces in an opposite direction to the second pole (5125b), and a fourth pole (5510b) (e.g., an N pole) of a second magnetic member (5510) is in contact with one surface (551) of a second bracket (550), and a third pole (5510a) (e.g., an S pole) faces in an opposite direction to the fourth pole (5510b). Of course, the arrangement of the polarities illustrated herein may vary depending on the embodiment.

[0150] According to one embodiment, the coil portion (520) may have one end facing the first magnetic member (5125) and the other end facing the second magnetic member (5510). According to another embodiment, the coil portion (520) may include a first yoke (521) disposed at the one end and a second yoke (522) disposed at the other end. The first yoke (521) may be configured to face the first magnetic member (5125) and the second yoke (522) may be configured to face the second magnetic member (5510).

[0151] When current flows in the coil unit (520), if an attractive force (or repulsive force) is generated between the first magnetic member (5125) and the coil unit (520), a repulsive force (or attractive force) may be generated between the second magnetic member (5510) and the coil unit (520). The driving circuit (540) applies a current to the coil unit (520) through a pair of connecting coils (530), and by changing the direction in which the current flows (e.g., clockwise → counterclockwise, or counterclockwise → clockwise), the direction of the magnetic field formed in the coil unit (520) may be changed. When the direction of the magnetic field formed in the coil unit (520) is changed, a repulsive force (or attractive force) is generated between the first magnetic member (5125) and the coil unit (520), and an attractive force (or repulsive force) may be generated between the second magnetic member (5510) and the coil unit (520).

[0152] Referring to FIG. 24, a button assembly (500) according to one embodiment may be arranged such that a second pole (5125b) (e.g., an N pole) of a first magnetic member (5125) is in contact with one surface (e.g., a second surface (512)) of a body portion (510), and a first pole (5125a) (e.g., an S pole) faces in an opposite direction to the second pole. And, the fourth pole (5510b) (e.g., N pole) of the second magnetic member (5510) may be placed in contact with one side of the body part (510) of the second bracket (550) (e.g., the side (551) facing the second side (512), and the third pole (5510a) (e.g., S pole) may be placed in a state opposite to the fourth pole (5510b). At this time, when a current flowing in and out of the coil part (520) in a counterclockwise direction from the connection coil (530) flows to the coil part (520), one end of the coil part (520) may have a different polarity (e.g., N pole) from the first pole (5125a) (e.g., S pole) of the first magnetic member (5125), so that an attractive force may be generated between the first magnetic member (5125) and the coil part (520). The body part (510) can move in the fourth direction (-X-axis direction). When a current flowing in and out of the coil part (520) in a clockwise direction from the connection coil (530) flows to the coil part (520), and one end of the coil part (520) has the same polarity (e.g., S pole) as the first pole (5125a) (e.g., S pole) of the first magnetic member (5125), a repulsive force can be generated between the first magnetic member (5125) and the coil part (520). Accordingly, the body part (510) can move in the third direction (+X-axis direction).

[0153] As previously described in FIG. 4, the electronic device (101) may further include a sensor (e.g., 222) for sensing an input when a user touches the button assembly described above (e.g., the button assembly (300) of FIGS. 10 to 15, the button assembly (400) of FIGS. 16 to 22, the button assembly (500) of FIGS. 23 and 24). In addition, the electronic device (101) may include the button assembly of the present disclosure (e.g., the button assembly (300) of FIGS. 10 to 15, the button assembly (400) of FIGS. 16 to 22, the button assembly (500) of FIGS. 23 and 24) in order to provide a corresponding tactile sensation or other kinesthetic sensation when receiving a user's touch input through the sensor. The electronic device (101) of the present disclosure can convert electrical energy applied to a coil portion (e.g., a coil portion (320) of FIGS. 10 to 15, a coil portion (420) of FIGS. 16 to 22, a coil portion (520) of FIGS. 23 and 24) into mechanical energy that moves the body portion (e.g., a body portion (310) of FIGS. 10 to 15, a body portion (410) of FIGS. 16 to 22, a body portion (510) of FIGS. 23 and 24) in one direction or the other direction. Here, the one direction or the other direction of the body portion may correspond to any one of a first direction (e.g., a +Y-axis direction), a second direction (e.g., a -Y-axis direction), a third direction (e.g., a +X-axis direction), and a fourth direction (e.g., a -X-axis direction).The electronic device (101) of the present disclosure includes a button assembly (e.g., a button assembly (300) of FIGS. 10 to 15, a button assembly (400) of FIGS. 16 to 22, a button assembly (500) of FIGS. 23 and 24) that is provided separately from a haptic module (e.g., a haptic module (179) of FIG. 1, a vibration motor (260) of FIG. 6) and is capable of providing a separate haptic feedback, thereby providing a user with a more localized, more precise, and more diverse user experience (UX).
