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).

[0039] 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.

In this respect, at least a portion of the front plate (202), the frame structure (240), and / or the rear plate (211) that form the exterior of the electronic device (200) may be referred to as the housing (210) of the electronic device (200).

[0090] Figure 3 is a partially exploded perspective view of an exemplary electronic device.

[0091] Referring to FIG. 3, the electronic device (101) may include a housing (210) including one or more holes (310) (or recesses), one or more key buttons (320) (e.g., the key input device (217) of FIG. 2A), one or more dome keys (340), and a printed circuit board (350).

[0092] The housing (210) may define an internal space of the electronic device (101) for accommodating electronic components (e.g., a printed circuit board (350)) of the electronic device (101). For example, the housing (210) may include a front surface (e.g., a front surface (200A) of FIG. 2A), a rear surface (e.g., a rear surface (200B) of FIG. 2A) facing the front surface (200A), and a side surface (200C) surrounding a space between the front surface (200A) and the rear surface (200B). The space surrounded by the front surface (200A), the rear surface (200B), and the side surface (200C) may be referred to as an internal space of the electronic device (101).

[0093] One or more holes (310) may be formed in the housing (210). In one embodiment, the one or more holes (310) may include a recess. The one or more holes (310) may provide seating spaces for accommodating one or more key buttons (320). For example, the one or more holes (310) may extend from a side surface (200C) of the housing (210) toward the interior of the electronic device (101). One or more of the one or more holes (310) may extend from the front surface (200A) toward the interior of the electronic device. One or more of the one or more holes (310) may extend from the rear surface (200B) toward the interior of the electronic device. One or more holes (310) may be formed in a side bezel structure of the housing (210) forming a side surface (200C) of the housing (210) (e.g., the side bezel structure (218) of FIG. 2A). The one or more holes (310) may be formed along the side surface (200C). For example, a first hole (311) may be passed through by a first key button (321) such that the first key button (321) interacts with a first dome key (341) located within the electronic device (101). A second hole (312) spaced apart from the first hole (311) may be passed through by the second key button (322) such that the second key button (322) interacts with a second dome key (342) and a third dome key (343) located within the electronic device (101). However, the embodiments supported by the present disclosure are not limited thereto. However, the embodiments supported by the present disclosure are not limited thereto, and the electronic device (101) may include a plurality of key buttons configured to trigger various functions of the electronic device (101) and a plurality of holes for accommodating the plurality of key buttons.

[0094] One or more key buttons (320) may be movably coupled within one or more holes (310), respectively. For example, one or more key buttons (320) may be partially disposed within one or more holes (310), respectively, so as to be exposed to the outside of the electronic device (101). The one or more key buttons (320) may move in the pressing direction (e.g., -x direction) when pressed in the pressing direction. The one or more key buttons (320) may be configured to move in the opposite direction of the pressing direction (e.g., +x direction) and be restored when the pressing is released.

[0095] A printed circuit board (350) may be disposed within the housing (210) toward one or more key buttons (320) and / or one or more holes (310) in which the one or more key buttons (320) are disposed. One or more dome keys (340) may be mounted on the printed circuit board (350) so as to be disposed toward the one or more key buttons (320), respectively. For example, the printed circuit board (350) may be disposed within the internal space of the electronic device (101) toward a side surface (200C) of the housing (210). One or more dome keys (340) may be disposed on one surface of the printed circuit board (350) facing the side surface (200C). For example, the first dome key (341) may overlap the first key button (321) when the first key button (321) is viewed from above (e.g., when viewed in the -x direction). The second dome key (342) and the third dome key (343) may overlap the second key button (322) when the second key button (322) is viewed from above. For example, one or more dome keys (340) may be configured to interlock with one or more key buttons (320) to obtain an input signal, respectively. The one or more dome keys (340) may be aligned with the one or more key buttons (320) so as to be pressed by the one or more key buttons (320), respectively. The one or more dome keys (340) may be configured to obtain an input signal, respectively, by being pressed by the corresponding one or more key buttons (320).

[0096] For example, the first dome key (341) may cause the execution of a power on / off function of the electronic device (101) or the execution of an artificial intelligence function of the electronic device (101) when pressed by the first key button (321). For example, the second dome key (342) and the third dome key (343) may cause the execution of a volume up / down function of the electronic device (101) or the execution of a wake up / sleep function of the electronic device (101) when pressed by the second key button (322). However, the embodiment supported by the present disclosure is not limited thereto, and the electronic device (101) may include a plurality of key buttons for executing various functions of the electronic device (101), and a plurality of dome keys corresponding to each of the plurality of key buttons.

[0097] A processor (e.g., processor (120) of FIG. 1) may receive an input signal obtained through one or more dome keys (340). In the present disclosure, the processor (120) may be referred to as at least one processor or one or more processors including a processing circuit within the electronic device (101). In addition, instructions stored in one or more storage media included in a memory (e.g., memory (130) of FIG. 1) within the electronic device (101), when individually or collectively executed by the processor (120), may cause the electronic device (101) to perform operations and / or functions of the electronic device (101) assigned to each of the one or more dome keys (340).

[0098] For example, in response to receiving a first input signal acquired through a first dome key (341), the processor (120) may execute a power on / off function of the electronic device (101), which is a function assigned to the first input signal. For example, in response to receiving a second input signal acquired through a second dome key (342), the processor (120) may execute a volume increase function of the electronic device (101), which is a function assigned to the second input signal. For example, in response to receiving a third input signal acquired through a third dome key (343), the processor (120) may execute a volume decrease function of the electronic device (101), which is a function assigned to the third input signal. However, the functions of the electronic device (101) caused by one or more key buttons (320) and one or more dome keys (340) are not limited thereto.

[0099] One or more dome keys (340) may be deformed based on pressure applied by one or more key buttons (320). When the pressure applied to the one or more dome keys (340) is released, the one or more dome keys (340) may be restored to a state prior to the pressure being applied. The one or more dome keys (340) may provide mechanical haptic feedback via the one or more key buttons (320) while being pressed or restored by the one or more key buttons (320).

[0100] In order to provide various user experiences, the electronic device (101) may be required to provide various haptic feedbacks in addition to the haptic feedback provided when the one or more dome keys (320) are pressed. For example, the electronic device (101) may be required to provide different haptic patterns depending on the pressure applied through the one or more key buttons (320), or to provide different haptic feedbacks depending on the user input entered through the one or more key buttons (320). In order to provide various haptic feedbacks, the electronic device (101) may be required to have a structure for providing various haptic feedbacks and a connection structure around the one or more key buttons (320) for controlling the haptic feedbacks through the structure, instead of the one or more dome keys (320). The structure of the key button (or key button assembly) of the electronic device (101) for providing the various haptic feedbacks is exemplarily described through the illustrations in FIG. 4A and below.

[0101] Figure 4a illustrates the internal structure of an exemplary electronic device. Figures 4b and 4c are exploded views of a key button assembly of the exemplary electronic device. Figure 4d is an exploded perspective view of a key button assembly of the exemplary electronic device.

[0102] Referring to FIGS. 4A, 4B, 4C, and 4D, an electronic device (101) according to one embodiment may include a housing (210) including a recess (410), a key button (420) (e.g., the key input device (217) of FIG. 2A, or one or more key buttons (320) of FIG. 3), a printed circuit board (350), an actuator (430), and / or a sensor (450).

[0103] According to one embodiment, the recess (410) of the housing (210) can provide a seating space for the key button (420). The recess (410) can be recessed, for example, from a side surface (200C) of the housing (210) toward the interior of the electronic device (101). For example, the recess (410) can partially accommodate the key button (420). For example, the recess (410) can be formed to allow the key button (420) to move relative to the housing (210) based on pressure applied from the outside by providing a space in which the key button (420) can move.

[0104] According to one embodiment, the housing (210) may include a first support portion (214) for supporting a key button (420). A head portion (421) of the key button (420) may be seated in the first support portion (214). For example, the first support portion (214) may form a recess (410) of the housing (210). For example, the first support portion (214) may reduce the head portion (421) from being dislodged from the recess (410) by pressure applied to the key button (420) by supporting the head portion (421).

[0105] According to one embodiment, the housing (210) may include a second support portion (215) forming a space (S) for accommodating a printed circuit board (350). For example, the second support portion (215) may support the printed circuit board (350) and / or electrical components (e.g., actuators (430) or sensors (450)) disposed on the printed circuit board (350) and for providing various haptic feedbacks to the key button (420). For example, the space (S) formed by the second support portion (215) may be a space for accommodating a key button assembly (400) as exemplarily illustrated and described in FIGS. 4b to 4d , but the embodiment is not limited thereto.

[0106] According to one embodiment, the housing (210) may include a through hole (415) connected to a recess (410). For example, the through hole (415) may pass through a first support portion (214) for fixing a head portion (421). The through hole (415) may connect a recess (410) defined by the first support portion (214) and a space (S) formed by the second support portion (215). For example, the through hole (415) may be passed through by a shaft portion (422) of a key button (420). The through hole (415) may at least partially accommodate the shaft portion (422). For example, the through hole (415) may include a first through hole (415a) penetrated by the first shaft portion (422a) and a second through hole (415b) penetrated by the second shaft portion (422b), but the embodiment is not limited thereto.

[0107] According to one embodiment, the key button (420) may include a head portion (421) partially disposed within a recess (410) of the housing (210), and a shaft portion (422) extending from the head portion (421) toward the interior of the electronic device (101). For example, the head portion (421) may be partially inserted within the recess (410) of the housing (210). The head portion (421) may be at least partially exposed to the exterior of the electronic device (101). For example, the head portion (421) may partially protrude outside the recess (410) to form a step with respect to the side surface (200C) of the housing (210). For example, the head portion (421) may be seated on a first support portion (214) that provides the recess (410) of the housing (210). The above head portion (214) can be movably coupled to the first support portion (214).

[0108] For example, the shaft portion (422) may protrude from the head portion (421) toward the interior of the electronic device (101). The shaft portion (422) may be configured to come into contact with components (e.g., an actuator (430)) within the electronic device (101) by penetrating a through hole (415) connected to a recess (410) of the housing (210). For example, the shaft portion (422) may be partially disposed within the through hole (415). The shaft portion (422) may pressurize the actuator (430) that comes into contact with the shaft portion (422) based on the pressure applied to the head portion (421). The shaft portion (422) may be configured to transmit pressure applied to the head portion (421) to an actuator (430) and / or sensor (450) inside the electronic device (101).

[0109] For example, the shaft portion (422) may include a first shaft portion (422a) and a second shaft portion (422b) that extend from the head portion (421) and are spaced apart from each other. For example, the first shaft portion (422a) and the second shaft portion (422b) may each protrude from opposite ends of the head portion (421) toward the interior of the electronic device (101). For example, the first shaft portion (422a) may extend from the head portion (421) through the first through-hole (415a) into the space (S) of the housing (210), thereby coming into contact with the first actuator (431) within the space (S). The second shaft portion (422b) can be brought into contact with the second actuator (432) within the space (S) by extending from the head portion (421) through the second through hole (415b). However, the embodiments supported in the present disclosure are not limited thereto.

[0110] According to one embodiment, the key button (420) may include a hook portion (425) extending from the head portion (421). The hook portion (425) may be coupled to the housing (210) to prevent the key button (420) from being dislodged from the recess (410) of the housing (210). For example, the hook portion (425) may be engaged with or fastened to the first support portion (214) on which the head portion (421) of the key button (420) is seated. For example, the hook portion (425) may be positioned between the shaft portions (422a, 422b). The hook portion (425) may be coupled to the housing (210) to reduce the key button (420) from being dislodged from the recess (410) of the housing (210). However, the embodiment is not limited thereto, and the key button (420) and / or the housing (210) may include various fastening parts to reduce the key button (420) from coming out of the recess (410).

[0111] According to one embodiment, a printed circuit board (350) may be disposed within the housing (210) facing the key button (420). The printed circuit board (350) may include a flexible printed circuit board and / or a rigid-flex printed circuit board. For example, the printed circuit board (350) may be disposed within a space (S) formed by a second support portion (215) of the housing (210). The printed circuit board (350) may be disposed within the space (S) facing the first support portion (214) on which the key button (420) is seated. For example, one or more electronic components (e.g., an actuator (430) or a sensor (450)) capable of interfacing with the key button (420) may be mounted on the printed circuit board (350). The printed circuit board (350) may be positioned around the key button (420) so that the one or more electronic components operate based on the pressure applied to the key button (420). For example, the printed circuit board (350) may be positioned toward the through hole (415) so that the actuator (430) disposed on the printed circuit board (350) faces the shaft portion (422) passing through the through hole (415).

[0112] In this disclosure, when an expression of a positional relationship between one element and another element (e.g., “on”, “over”, “beneath”, “below”, “next to”) is mentioned, it should be understood that one or more intermediate elements may exist between the two elements, unless an expression such as “directly” or “directly” is used, and it should be noted that the arrangement relationship between the two elements is not limited. For example, when one element is mentioned as being “on” another element, it may mean that one or more intermediate elements may exist between the two elements in addition to the element being attached to, inseparably joined to, or inseparably formed with the other element. For example, in this disclosure, “an actuator (430) disposed on a printed circuit board (350)” may mean that one or more intermediate elements (e.g., a support plate (470)) may exist between the printed circuit board (350) and the actuator (430). For example, in the present disclosure, “an actuator (430) disposed on a printed circuit board (350)” may mean “an actuator (430) disposed on the printed circuit board (350).” For example, “an actuator (430) disposed on a printed circuit board (350)” may mean “an actuator (430) facing the printed circuit board (350) and spaced apart from the printed circuit board (350).” However, the embodiments supported in the present disclosure are not limited thereto.

[0113] In one embodiment, an actuator (430) may be disposed between a printed circuit board (350) and a key button (420). The actuator (430) may be configured to provide haptic feedback to a head portion (421) of the key button (420) based on a pressure applied by a shaft portion (422) of the key button (420). For example, the actuator (430) may come into contact with a shaft portion (422) that has passed through a through hole (415). As the head portion (421) of the key button (420) is pressed, the shaft portion (422) may press the actuator (430). The actuator (430) may be configured to vibrate based on the pressure applied by the shaft portion (422). The actuator (430) may provide haptic feedback to the head portion (421) connected to the shaft portion (422) by transmitting vibration to the shaft portion (422) based on the pressure. For example, the actuator (430) may be configured to vibrate by generating mechanical displacement based on receiving an electrical signal. The actuator (430) may be referred to as a piezoelectric actuator in that it generates mechanical displacement based on an electrical signal, but the embodiments supported in the present disclosure are not limited thereto.

[0114] For example, the actuator (430) may include a first actuator (431) disposed toward the first shaft portion (422a), and a second actuator (432) disposed spaced from the first actuator (431) and disposed toward the second shaft portion (422b). Based on a pressure applied by the first shaft portion (422a), the first actuator (431) may be configured to provide haptic feedback to the head portion (421) through the first shaft portion (422a). Based on a pressure applied by the second shaft portion (422b), the second actuator (432) may be configured to provide haptic feedback to the head portion (422) through the second shaft portion (422b). For example, the internal structure of the electronic device (101) for providing haptic feedback to a key button (420) exemplarily illustrated and described in FIG. 4A and / or the key button assembly (400) exemplarily illustrated and described in FIGS. 4B to 4D may be referred to as a two-piezoelectric actuator system in that they each include actuators (431, 432) configured to provide haptic feedback, but the embodiments supported by the present disclosure are not limited thereto.

[0115] According to one embodiment, the actuator (430) may be required to provide various haptic feedbacks based on the pressure applied from the shaft portion (422) of the key button (420) in order to meet the user's needs. For example, the actuator (430) may be required to provide different haptic feedbacks depending on the magnitude of the pressure applied from the shaft portion (422). In order to provide various haptic feedbacks, the actuator (430) may be required to be electrically connected to a sensor (450) configured to detect the pressure and / or a printed circuit board (350) on which the sensor (450) is disposed. A structure for connecting the sensor (450) and / or the printed circuit board (350) to the actuator (430) for providing various haptic feedbacks is described below.

[0116] In one embodiment, the sensor (450) may be configured to detect pressure applied by the shaft portion (422). The printed circuit board (350) may include a seating portion (351) on which the sensor (450) is disposed and spaced apart from the actuator (430), and a connecting portion (352) extending from the seating portion (351) to electrically connect the actuator (430) and the seating portion (351). The connecting portion (352) may be deformable.

[0117] For example, the sensor (450) may be pressed by the shaft portion (422) to detect pressure applied from the shaft portion (422). The sensor (450) may be aligned with the shaft portion (422) so as to be pressed by the shaft portion (422). For example, the sensor (450) may overlap the shaft portion (422) of the key button (420) when the key button (420) is viewed from above (e.g., when viewed in the -x direction). For example, the sensor (450) may be positioned at a position corresponding to a through hole (415) penetrated by the shaft portion (422) in the mounting portion (351) of the printed circuit board (350). For example, the sensor (450) may be positioned on the printed circuit board (350) such that the central axis of the sensor (450) corresponds to the central axis of the shaft portion (422), but the embodiment is not limited thereto. For example, the sensor (450) may be referred to as a pressure sensor or a piezoelectric sensor in that it is configured to sense the pressure, but the embodiment supported by the present disclosure is not limited thereto.

[0118] For example, the sensor (450) may be mounted on a mounting portion (351) of a printed circuit board (350) and may include a first sensor (451) and a second sensor (452) that are spaced apart from each other. The first sensor (451) may be aligned with the first shaft portion (422a) so as to be pressed by the first shaft portion (422a). The first sensor (451) may overlap the first actuator (431) when the first shaft portion (422a) is viewed from above (e.g., when viewed in the -x direction). The second sensor (452) may be aligned with the second shaft portion (422b) so as to be pressed by the second shaft portion (422a). The second sensor (452) may overlap the second actuator (432) when the second shaft portion (422b) is viewed from above. However, the embodiment supported by the present disclosure is not limited thereto, and the electronic device (101) may include a plurality of sensors arranged on the printed circuit board (350) for detecting pressure applied by the key button (420).

[0119] For example, the mounting portion (351) of the printed circuit board (350) may be coupled with the sensor (450). The mounting portion (351) may be spaced apart from the actuator (430) (or the piezoelectric element (440)) for vibration of the actuator (430). The mounting portion (351) may support the sensor (450) pressed by the shaft portion (422). For example, in addition to the sensor (450), the mounting portion (351) may have various electronic components arranged for interlocking with the key button (420). The mounting portion (351) may have a substantially flat shape within the space (S) formed by the second support portion (215) of the housing (210), but the embodiments supported in the present disclosure are not limited thereto.

[0120] For example, the connecting portion (352) of the printed circuit board (350) may extend from the mounting portion (351) to connect the mounting portion (351) and the actuator (430). For example, the connecting portion (352) may extend from the mounting portion (351) to the actuator (430). For example, one end of the connecting portion (352) may be connected to the mounting portion (351), and the other end of the connecting portion (352) may be connected to the actuator (430). However, the embodiment is not limited thereto, and the connecting portion (352) may be formed integrally with the mounting portion (351).

[0121] For example, the connecting portion (352) may be at least partially bendable to connect the actuator (430) and the mounting portion (351) spaced from the actuator (430). For example, the connecting portion (352) may be deformable, thereby reducing a decrease in the vibration performance of the actuator (430) connected to the connecting portion (352). For example, the connecting portion (352) may be configured to guide the vibration (or deformation) of the actuator (430) by being connected to a side of the actuator (430), but the embodiments supported in the present disclosure are not limited thereto.

[0122] For example, the connecting portion (352) may include a first connecting portion (352a) connecting the mounting portion (351) and the first actuator (431), and a second connecting portion (352b) connecting the mounting portion (351) and a second actuator (432) spaced apart from the first actuator (431). The first actuator (431) may be configured to receive an electric signal through the first connecting portion (352a). The second actuator (432) may be configured to receive an electric signal through the second connecting portion (352b). However, the embodiments supported by the present disclosure are not limited thereto, and the printed circuit board (350) may include a plurality of connecting portions for connecting a mounting portion (351) on which a sensor is mounted and an actuator (430) spaced apart from the mounting portion (351).

[0123] According to one embodiment, the actuator (430) may include a piezoelectric element (440) that provides haptic feedback based on pressure applied by a key button (420), and a vibration plate (460) coupled to the piezoelectric element (440) to amplify vibrations generated from the piezoelectric element (440). For example, the piezoelectric element (440) may include electrodes that are connected to a connection portion (352) of a printed circuit board (350) in the actuator (430). The piezoelectric element (440) may generate vibrations based on an electrical signal received from the connection portion (352). For example, the vibration plate (460) may be configured to amplify vibrations generated from the piezoelectric element (440) by being attached to the piezoelectric element (440). The vibration plate (460) can amplify vibrations generated from the piezoelectric element (440) by separating the piezoelectric element (440) from the printed circuit board (350) (and / or the support plate (470)) and the shaft portion (422) of the key button (420).

[0124] For example, the first actuator (431) may include a first piezoelectric element (441) configured to vibrate based on pressure applied by a first shaft portion (422a), a first vibration plate (461) disposed between the first piezoelectric element (441) and the first shaft portion (422a), and a second vibration plate (462) disposed between the first piezoelectric element (441) and a mounting portion (351) of a printed circuit board (350). The first piezoelectric element (441) may be connected to a first connecting portion (352a) of the printed circuit board (350). The first vibration plate (461) and the second vibration plate (462) may provide haptic feedback to the head portion (421) by amplifying vibration of the first piezoelectric element (441) that vibrates based on pressure applied from the first shaft portion (422a). For example, the second actuator (432) may include a second piezoelectric element (442) configured to vibrate based on pressure applied by the second shaft portion (422b), a third vibration plate (463) disposed between the second piezoelectric element (442) and the second shaft portion (422b), and a fourth vibration plate (464) disposed between the second piezoelectric element (442) and a mounting portion (351) of a printed circuit board (350). The second piezoelectric element (442) may be connected to a second connecting portion (352b) of the printed circuit board (350). The third vibration plate (463) and the fourth vibration plate (464) may provide haptic feedback to the head portion (422) by amplifying vibration of the second piezoelectric element (442) that vibrates based on pressure applied from the second shaft portion (422b). However, the embodiments supported by the present disclosure are not limited thereto.

[0125] In one embodiment, the actuator (430) may be disposed on a first surface (351a) of the mounting portion (351) facing the key button (420) so as to be disposed toward the key button (420). For example, the sensor (450) may be disposed on a second surface (351b) of the mounting portion (352) opposite to the first surface (351a). For example, the connecting portion (352) of the printed circuit board (350) may extend from a side surface of the mounting portion (351) so as to connect the mounting portion (351) and the actuator (430).

[0126] For example, the mounting portion (351) of the printed circuit board (350) may be at least partially disposed between the actuator (430) and the sensor (450). The mounting portion (351) (and / or the support plate (470)) may space the actuator (430) and the sensor (450). For example, the sensor (450) may be aligned with the shaft portion (422) such that it is pressed by the shaft portion (422). The actuator (430) may be aligned with the shaft portion (422) and the sensor (450) such that it is pressed by the shaft portion (422). For example, the first actuator (431) may be aligned with the first shaft portion (422a) and the first sensor (451). The second actuator (432) can be aligned with the second shaft portion (422b) and the second sensor (452). The actuator (430) and the sensor (450) can be aligned with the shaft portion (422) of the key button (420), thereby improving the accuracy of the pressure applied from the shaft portion (422) measured by the sensor (450) while also improving the performance of the haptic feedback transmitted to the head portion (421) through the shaft portion (422).

[0127] For example, the connecting portion (352) may extend from a side of the mounting portion (351) where the sensor (450) is disposed to a side of the actuator (430) in order to connect the mounting portion (351) where the sensor (450) is disposed and the actuator (430). For example, the connecting portion (352) may be connected to one side of a piezoelectric element (440) included in the actuator (430). For example, the first piezoelectric element (441) of the first actuator (431) may include a front side (441a) to which a first vibration plate (461) is attached, a rear side (441b) opposite to the front side (441a) and to which a second vibration plate (462) is attached, and a side side (441c) extending from the front side (441a) to the rear side (441b). The first connecting portion (352a) can connect the mounting portion (351) and the side surface (441c) of the first piezoelectric element (441). The first connecting portion (352a) can extend along the side surface (441c) of the first piezoelectric element (441). For example, the second piezoelectric element (442) of the second actuator (432) can include a front surface (442a) to which a third vibration plate (463) is attached, a rear surface (442b) opposite to the front surface (442a) and to which a fourth vibration plate (464) is attached, and a side surface (442c) extending from the front surface (442a) to the rear surface (442b). The second connecting portion (352b) can connect the mounting portion (351) and the side surface (442c) of the second piezoelectric element (442). The second connecting portion (352b) may extend along the side surface (442c) of the second piezoelectric element (442). However, the embodiments supported by the present disclosure are not limited thereto.

[0128] The electronic device (101) may include a processor (120) connected to a sensor (450). The operations described below may be performed or caused by the electronic device (101) and / or a processor of the electronic device (101) (e.g., the processor (120) of FIG. 1), respectively. The processor (120) may be referred to as at least one processor or one or more processors including a processing circuit within the electronic device (101). In addition, instructions stored in one or more storage media included in a memory (e.g., the memory (130) of FIG. 1) within the electronic device (101), when individually or collectively executed by the processor (120), may cause the electronic device (101) to perform each of the operations described below.

[0129] For example, the processor (120) can identify the pressure detected from the sensor (450). Based on the identified pressure, the processor (120) can transmit a signal corresponding to the pressure to the actuator (430) (or the piezoelectric element (440)). The actuator (430) can be configured to vibrate to provide haptic feedback corresponding to the signal based on receiving the signal corresponding to the pressure. Through the vibration, the haptic feedback can be provided to the key button (420) (or the head portion (421)). Since the signal received by the actuator (430) is different depending on the pressure, the electronic device (101) can provide various haptic feedbacks depending on the pressure through the key button (420).

[0130] The electronic device (101) may include a support plate (470) attached on a first side (351a) of the mounting portion (351) facing the key button (420) to support an actuator (430) pressed by the shaft portion (422). A sensor (450) may be disposed on a second side (351b) of the mounting portion (351) opposite to the first side (351a). For example, the support plate (470) may be at least partially interposed between the mounting portion (351) and the actuator (430). The support plate (470) may support the actuator (430) pressed by the shaft portion (422). For example, the support plate (470) can support the actuator (430) in the opposite direction (e.g., +x direction) to the direction of the force applied by the shaft portion (422) (e.g., -x direction). For example, the support plate (470) can be attached to the first surface (351a) of the mounting portion (351) facing the key button (420), thereby reducing damage to the mounting portion (351) by the shaft portion (422) of the key button (420). For example, the support plate (470) can separate the mounting portion (351) from the actuator (430). The connection portion (352) of the printed circuit board (350) can electrically connect the mounting portion (351) separated by the support plate (470) and the actuator (430). However, the embodiments supported by the present disclosure are not limited thereto, and the electronic device (101) may include rigid structures and / or stiffeners for supporting the actuator (430) and the mounting portion (351).

[0131] Referring to FIGS. 4b to 4d, the electronic device (101) may include a key button assembly (400) including a key button (420), a printed circuit board (350), an actuator (430), and a sensor (450). The key button assembly (400) may function as a key button module, but is not limited thereto. The printed circuit board (350) may include, for example, a third connection portion (352c) connecting the key button assembly (400) and a printed circuit board (e.g., the first printed circuit board (250) of FIG. 2b, main PCB) on which the processor (120) of the electronic device (101) is disposed.

[0132] According to one embodiment, the electronic device (101) may include a spacer (480) for supporting a mounting portion (351) of a printed circuit board (350) within a housing (210), and an elastic member (485) interposed between the spacer (480) and the mounting portion (351). For example, the spacer (480) may be mounted on a second supporting portion (215) of the housing (210). The spacer (480) may be interposed between the second supporting portion (215) and the mounting portion (351) (or the key button assembly (400)), thereby being configured to bring the mounting portion (351) and / or the actuator (430) on the mounting portion (351) toward the key button (420). For example, an elastic member (485) may be disposed between a spacer (480) and a sensor (450). The elastic member (485) may be deformable to cushion an impact transmitted from the shaft portion (422) to the sensor (450) or to support the sensor (450). For example, the elastic member (485) may include a first elastic member (485a) aligned with a first sensor (451) and a second elastic member (485b) aligned with a second sensor (452), but the embodiments supported in the present disclosure are not limited thereto.

[0133] According to one embodiment, the electronic device (101) may include a seal (490) surrounding a side surface of the shaft portion (422). For example, the seal (490) may be fastened to the shaft portion (422) and disposed within the through hole (415) in which the shaft portion (422) is positioned. The seal (490) may be interposed between the shaft portion (422) and the inner surface of the through hole (415), thereby separating the space (S) in which electronic components (e.g., the actuator (430) or the sensor (450)) are disposed from the outside of the electronic device (101) (or the recess (410)). The seal (490) may reduce the inflow of foreign substances from the outside of the electronic device (101) into the space (S) in which electronic components are disposed by occupying the through hole (415) together with the shaft portion (422). For example, the seal (490) may include a first seal (491) disposed within a first through hole (415a) together with a first shaft portion (422a) and a second seal (492) disposed within a second through hole (415b) together with a second shaft portion (422b), but the embodiments supported in the present disclosure are not limited thereto.

[0134] According to the above-described embodiment, the electronic device (101) (or key button assembly (400)) can provide a variety of user experiences to the user by including a sensor (450) for detecting a pressure applied by a key button (420), and an actuator (430) configured to provide various haptic feedbacks to the key button (420) according to the pressure. The electronic device (101) includes a mounting portion (351) on which the sensor (450) is disposed and spaced apart from the actuator (430), and a connecting portion (352) connecting the mounting portion (351) and the actuator (430), thereby improving the accuracy of the pressure applied from the key button (420) measured by the sensor (450) while improving the performance of the haptic feedback provided through the key button (420).

[0135] FIG. 5A is a partial cross-sectional view of an exemplary electronic device taken along line A-A' of FIG. 2A. FIG. 5B is a partial cross-sectional view of an exemplary electronic device taken along line B-B' of FIG. 5A. FIG. 5C and FIG. 5D illustrate a key button assembly of the exemplary electronic device.

[0136] Referring to FIGS. 5A, 5B, and 5C, an electronic device (101) may include a housing (210) including a recess (410). The electronic device (101) may include a key button (420) including a head portion (421) partially disposed within the recess (410) and a shaft portion (422) extending from the head portion (421) toward the interior of the electronic device (101). The electronic device (101) may include a printed circuit board (350) disposed within the housing (210) toward the key button (420). The electronic device (101) may include an actuator (430) disposed between the printed circuit board (350) and the key button (420) and configured to provide haptic feedback to the head portion (421) based on pressure applied by the shaft portion (422). The electronic device (101) may include a sensor (450) configured to detect the pressure. The printed circuit board (350) may include a mounting portion (351) on which the sensor is disposed and spaced apart from the actuator (430), and a deformable connecting portion (352) extending from the mounting portion (351) to electrically connect the actuator (430) and the mounting portion (351). However, the embodiments supported by the present disclosure are not limited thereto, and the electronic device (101) exemplarily illustrated and described in FIGS. 5A to 5D may include components (e.g., a hook portion (425), an elastic member (485), or a seal (490)) exemplarily illustrated and described in FIGS. 4A to 4D. In addition, in the following, overlapping descriptions of components having the same reference numerals as exemplarily illustrated in FIGS. 4A to 4D are omitted to the extent that the examples are not contradictory or inconsistent with each other.

[0137] Referring to FIGS. 5A to 5D , unlike FIGS. 4A to 4D , the electronic device (101) (or key button assembly (400)) may include one actuator (430) configured to provide haptic feedback via the key button (420). For example, the internal structure of the electronic device (101) for providing haptic feedback to the key button (420) exemplarily illustrated and described in FIGS. 5A and 5B and / or the key button assembly (400) exemplarily illustrated and described in FIGS. 5C and 5D may be referred to as one piezoelectric actuator system in that each includes one actuator (430) (or piezoelectric element (440)) configured to provide haptic feedback, but embodiments supported by the present disclosure are not limited thereto.

[0138] Unlike the examples illustrated and described in FIGS. 4A to 4D , the actuator (430) and the sensor (450) may be respectively disposed on the first surface (351a) of the mounting portion (351) facing the key button (420). For example, the first sensor (451), the second sensor (452), and the actuator (430) may be coupled to the first surface (351a) of the mounting portion (351). A support plate (470) for supporting the mounting portion (351) may be attached to a second surface (351b) opposite to the first surface (351a), unlike FIGS. 4A to 4D . The support plate (470) may be disposed, for example, between the mounting portion (351) and the spacer (480). The actuator (430) may be disposed, for example, between the first sensor (451) and the second sensor (452), but the embodiment is not limited thereto.

[0139] According to one embodiment, the electronic device (101) may include a support member (510) interposed between a mounting portion (351) of a printed circuit board (350) and the actuator (430) to support the actuator (430). For example, the support member (510) may be disposed between a first surface (351a) of the mounting portion (351) and the actuator (430). The support member (510) may guide the position of the actuator (430) by supporting the actuator (430) so that the actuator (430) is pressed by the shaft portion (422) of the key button (420). For example, the support member (510) may be a rigid body (e.g., metal) having a relatively greater rigidity than the actuator (430), but the embodiment is not limited thereto.

[0140] In one embodiment, the connecting portion (352) can be configured to fold back on itself on the first surface (351a) so as to extend from the mounting portion (351) to an actuator (430) disposed on the first surface (351a) of the mounting portion (351). For example, the first connecting portion (352a) can be connected to a second portion (430b) of the actuator (430). The first connecting portion (352a) can be bent on the first surface (351a) of the mounting portion (351) to connect the mounting portion (351) and the second portion (430b) spaced apart from the mounting portion (351) by the supporting member (510). The second connecting portion (352b) can be connected to the third portion (430c) of the actuator (430). The second connecting portion (352b) can be bent on the first surface (351a) of the mounting portion (351) to connect the mounting portion (351) and the third portion (430c) spaced apart from the mounting portion (351) by the support member (510). For example, the connecting portion (352) can be deformable to guide the portions (430b, 430c) forming both ends of the actuator (430) to generate displacement, but the embodiments supported in the present disclosure are not limited thereto.

[0141] According to one embodiment, the actuator (430) may include a first portion (430a) attached to a support member (510), a second portion (430b) deformable by being pressed by the first shaft portion (422a), and a third portion (430c) deformable by being pressed by the second shaft portion (422b). The second portion (430b) may form one end of the actuator (430). The third portion (430c) may form the other end of the actuator (430) opposite the one end.

[0142] For example, the first portion (430a) may be a portion supported by the support member (510). The first portion (430a) may overlap the support member (510). The first portion (430a) may be supported by the support member (510) so that the displacement thereof may be fixed against the pressure applied by the shaft portion (422). For example, the second portion (430b) may be configured to generate a displacement based on the pressure applied by the first shaft portion (422a). The second portion (430b) may be pressed by the first shaft portion (422a) together with the first sensor (451). Based on the pressure detected from the first sensor (451), the second portion (430b) can provide haptic feedback to the head portion (421) through the first shaft portion (422a). For example, the third portion (430c) can be configured to generate displacement based on the pressure applied by the second shaft portion (422b). The third portion (430c) can be pressed by the second shaft portion (422b) together with the second sensor (452). Based on the pressure detected from the second sensor (452), the third portion (430c) can provide haptic feedback to the head portion (421) through the second shaft portion (422b). However, the embodiments supported in the present disclosure are not limited thereto.

[0143] For example, the first connecting portion (352a) may be pressed by the first shaft portion (422a) together with the second portion (430b) of the actuator (430) connected to the first connecting portion (352a) and the first sensor (451) disposed around the first connecting portion (352a). The actuator (430) may receive a signal for haptic feedback corresponding to the pressure through the first connecting portion (352a) based on the pressure detected by the first sensor (451). Based on the received signal, the actuator (430) may provide the haptic feedback corresponding to the pressure. While the actuator (430) provides the haptic feedback, the first connecting portion (352a) may be deformable and coupled to the second portion (430b) such that the second portion (430b) of the actuator (430) causes displacement. For example, the second connecting portion (352b) may be pressed by the second shaft portion (422b) together with the third portion (430c) of the actuator (430) connected to the second connecting portion (352b) and a second sensor (452) disposed around the second connecting portion (352b). The actuator (430) may receive a signal for haptic feedback corresponding to the pressure through the second connecting portion (352b) based on the pressure detected by the second sensor (452). Based on the received signal, the actuator (430) can provide the haptic feedback corresponding to the pressure. While the actuator (430) provides the haptic feedback, the second connecting portion (352b) can be deformable and coupled to the third portion (430c) of the actuator (430) such that the third portion (430c) generates displacement. However, the embodiments supported in the present disclosure are not limited thereto.

[0144] According to one embodiment, the electronic device (101) may include a waterproof member (520) that is connected to a recess (410) of the housing (210) and covers a through-hole (415) penetrated by a shaft portion (422) to isolate the inside of the electronic device (101) from the outside of the electronic device (101). The waterproof member (520) may be configured to contact parts (430b, 430c) that generate displacement of the sensor (450) and the actuator (430) by the shaft portion (422). For example, the waterproof member (520) may cover the through-hole (415) within a space (S) formed by the second support portion (215) of the housing (210). The waterproof member (520) can separate the space (S) where electronic components (e.g., actuator (430) or sensor (450)) are arranged from the outside (or recess (410)) of the electronic device (101). The waterproof member (520) can reduce foreign substances from entering the space (S) where electronic components are arranged from the outside of the electronic device (101) by covering the through hole (415). For example, the waterproof member (520) may include a first waterproof member (521) configured to cover the first through hole (415a) and be pressed by a first shaft portion (422a), and a second waterproof member (522) configured to cover the second through hole (415b) and be pressed by a second shaft portion (422b), but the embodiments supported in the present disclosure are not limited thereto.

[0145] According to one embodiment, the electronic device (101) may include a support structure (530) that supports the waterproof member (520) to prevent the waterproof member (520) from being separated from the through hole (415). The support structure (530) may be coupled to a first surface (351a) of the mounting portion (351). The support structure (530) may surround, for example, the actuator (430) and / or the sensor (450). For example, the support structure (530) may be disposed between the mounting portion (351) and the waterproof member (520). The support structure (530) may include a hole for passing the waterproof member (520) (or the shaft portion (422)).

[0146] According to one embodiment, the electronic device (101) may include a guide member (540) disposed between a mounting portion (351) of a printed circuit board (350) and a waterproof member (520). The guide member (540) may be configured to support the waterproof member (520) so that a force is applied to the waterproof member (520) in a second direction (e.g., +x direction) opposite to the first direction, in order to limit the range of movement of the shaft portion (422) in a first direction (e.g., -x direction) toward the inside of the electronic device (101) from the head portion (421) of the key button (420). For example, the guide member (540) may be disposed on a first surface (351a) of the mounting portion (351). For example, the guide member (540) may be positioned between the mounting portion (351) and the waterproof member (520) (and / or the support structure (530)). The guide member (540) may include, for example, a first guide member (541) for supporting a first waterproof member (521) and a second guide member (542) for supporting a second waterproof member (522), but the embodiment is not limited thereto.

[0147] For example, referring to FIG. 5b, the waterproof member (520) may include a first waterproof portion (520a) configured to be pressed by a shaft portion (422), and a second waterproof portion (520b) connected to the first waterproof portion (520a) and supported by a support structure (530). The first waterproof portion (520a) may be in contact with the shaft portion (422). The first waterproof portion (520a) may be in contact with a sensor (450) and an actuator (430) on a mounting portion (351). The first waterproof portion (520a) may pressurize the sensor (450) and the actuator (430) by being pressed by the shaft portion (422). For example, the second waterproof portion (520b) can seal the edge of the through hole (415) formed in the first support portion (214) by coming into contact with the first support portion (214) of the housing (210) forming the recess (410). For example, the second waterproof portion (520b) can be in close contact with the first support portion (214) by being supported by the support structure (530).

[0148] For example, the guide member (540) can support the second waterproof portion (520b) (or the support structure (530)). For example, the first waterproof portion (520a) can be moved or deformed in a first direction (e.g., -x direction) by being pressed by the shaft portion (422). The second waterproof portion (520b) connected to the first waterproof portion (520a) can receive a force in the first direction by the shaft portion (422). The support structure (530) and / or the guide member (540) can reduce the second waterproof portion (520b) from being separated from the edge of the through hole (415) by the shaft portion (422) by supporting the second waterproof portion (520b) in a second direction opposite to the first direction (e.g., +x direction).

[0149] According to the above-described embodiment, the electronic device (101) (or key button assembly (400)) can provide a variety of user experiences to the user by including a sensor (450) for detecting a pressure applied by a key button (420), and an actuator (430) configured to provide various haptic feedbacks to the key button (420) according to the pressure. The electronic device (101) includes a mounting portion (351) on which the sensor (450) is disposed and spaced apart from the actuator (430), and a connecting portion (352) connecting the mounting portion (351) and the actuator (430), thereby improving the accuracy of the pressure applied from the key button (420) measured by the sensor (450) while improving the performance of the haptic feedback provided through the key button (420).

[0150] Figure 6 illustrates the internal structure of an exemplary electronic device in which a key button assembly is arranged.

[0151] Referring to FIG. 6, a key button assembly (400) exemplarily illustrated and described in FIGS. 5A to 5D may be disposed within an electronic device (101). The key button assembly (400) may include, for example, the components exemplarily illustrated in FIGS. 5A to 5D (e.g., a key button (420), a printed circuit board (350), an actuator (430), or a sensor (450)). For example, the key button assembly (400) may be disposed toward a side surface (200C) of the housing (210). The key button (420) of the key button assembly (400) may be partially exposed to the outside of the electronic device (101), for example, through the side surface (200C).

[0152] The key button assembly (400) exemplarily illustrated and described in FIGS. 5A to 5D may, unlike the key button assembly (400) exemplarily illustrated and described in FIGS. 4A to 4D, omit the vibration plate (460) of the actuator (430). The key button assembly (400) may include a support member (e.g., the support member (510) of FIG. 5A) for supporting the actuator (430) (or the piezoelectric element (440)). The key button assembly (400) may reduce the overall thickness of the key button assembly (400) by including the support member (510) for supporting the actuator (430) instead of the vibration plate (460). In addition, unlike the key button assembly (400) exemplarily illustrated and described in FIGS. 4A to 4D, the key button assembly (400) can reduce the overall thickness of the key button assembly (400) by having both the sensor (450) and the actuator (430) disposed on the first surface (e.g., the first surface (351a) of FIG. 4B) of the support portion (e.g., the support portion (351) of FIG. 4A) of the printed circuit board (350) facing the key button (420).

[0153] According to one embodiment, the key button assembly (400) may be disposed around a plurality of cameras (620) (or camera modules) within the electronic device (101). The key button assembly (400) may have a relatively small thickness to provide additional space for the plurality of cameras (620) to be disposed. For example, the key button assembly (400) may be disposed along the plurality of cameras (620). The key button assemblies (400) may be spaced apart from each other, for example, by a second support portion of the housing (210) for supporting the key button assemblies (400) (e.g., the second support portion (215) of FIG. 4A), but the embodiment is not limited thereto.

[0154] According to one embodiment, the printed circuit board (350) of the key button assembly (400) may include a third connection portion (352c) that connects a mounting portion (351) of the printed circuit board (350) and another printed circuit board (610) (e.g., the first printed circuit board (250), main PCB of FIG. 2b) on which a processor (e.g., processor (120) of FIG. 1) within the electronic device (101) is mounted. Through the third connection portion (352c), the actuator (430) connected to the other printed circuit board may receive a signal related to haptic feedback from the processor (120).

[0155] According to the above-described embodiment, the key button assembly (400) can reduce the thickness of the entire key button assembly (400) by including one actuator (430) configured to provide haptic feedback to the key button (420). The key button assembly (400) has a relatively thin thickness, thereby providing additional space for electronic components (e.g., multiple cameras (620)) of an electronic device (101) disposed around the key button assembly (400).

[0156] Figures 7a and 7b illustrate the internal structure of an exemplary electronic device.

[0157] Referring to FIGS. 7A and 7B, an electronic device (101) may include a housing (210) including a recess (410). The electronic device (101) may include a key button (420) including a head portion (421) partially disposed within the recess (410) and a shaft portion (422) extending from the head portion (421) toward the interior of the electronic device (101). The electronic device (101) may include a printed circuit board (350) disposed within the housing (210) toward the key button (420). The electronic device (101) may include an actuator (430) disposed between the printed circuit board (350) and the key button (420) and configured to provide haptic feedback to the head portion (421) based on a pressure applied by the shaft portion (422). The electronic device (101) may include a sensor (450) configured to detect the pressure. The printed circuit board (350) may include a mounting portion (351) on which the sensor (450) is disposed and spaced apart from the actuator (430), and a deformable connecting portion (352) extending from the mounting portion (351) to electrically connect the actuator (430) and the mounting portion (351). However, the embodiments supported by the present disclosure are not limited thereto, and the electronic device (101) exemplarily illustrated and described in FIGS. 7A and 7B may include the configurations exemplarily illustrated and described in FIGS. 4A to 4D. In addition, in the following, overlapping descriptions of configurations having the same reference numerals as those exemplarily illustrated in FIGS. 4A to 4D are omitted to the extent that the examples are not contradictory or inconsistent with each other.

[0158] As the actuator (430) vibrates to provide haptic feedback, the electronic device (101) may require a structure to fix the position of the actuator (430) to stably provide the haptic feedback. For example, the first actuator (431) may be required to be aligned with the first shaft portion (422a) to provide haptic feedback to the head portion (421) through the first shaft portion (422a). The second actuator (432) may be required to be aligned with the second shaft portion (422b) to provide haptic feedback to the head portion (421) through the second shaft portion (422b). A structure for fixing and / or guiding the position of the actuator (430) of the electronic device (101) (or the key button assembly (400) of FIG. 4b) is illustrated and described in FIGS. 7a and 7b.

[0159] Referring to FIG. 7A, in one embodiment, the vibration plate (460) of the actuator (430) may include a guide groove that is recessed toward the piezoelectric element (440) of the actuator (430). The electronic device (101) may include a first guide structure (710) that is attached to the mounting portion (351) and protrudes into the guide groove. The first guide structure (710) may be aligned with the actuator (430), the shaft portion (422), and the sensor (450) to guide the position of the actuator (430), but embodiments supported by the present disclosure are not limited thereto.

[0160] For example, the first actuator (431) may include a first vibration plate (461) including a first guide groove (461a) sunken toward one side of the first piezoelectric element (441) (e.g., the front side (441a) of FIG. 4b), and a second vibration plate (462) including a second guide groove (462a) sunken toward the other side of the first piezoelectric element (441) opposite to the one side (e.g., the rear side (441b) of FIG. 4b). For example, the second actuator (432) may include a third vibration plate (463) including a third guide groove (463a) sunken toward one side of the second piezoelectric element (442) (e.g., the front side (442a) of FIG. 4b), and a fourth vibration plate (464) including a fourth guide groove (464a) sunken toward the other side of the second piezoelectric element (442) opposite to the one side (e.g., the rear side (442b) of FIG. 4b). For example, the first guide structure (710) may include a first guide portion (711) protruding from the first surface (351a) of the mounting portion (351) into the second guide groove (462a) of the second vibration plate (462), and a second guide portion (712) protruding from the first surface (351a) into the fourth guide groove (464a) of the fourth vibration plate (464). The first guide portion (711) may be fastened into the second guide groove (462a) to fix the position of the first actuator (431) while the first actuator (431) provides haptic feedback. The second guide portion (712) is fastened within the fourth guide groove (464a) to fix the position of the second actuator (432) while the second actuator (432) provides haptic feedback. However, the embodiment is not limited thereto.

[0161] For example, although not shown, the shaft portion (422) may include a protrusion (not shown) for fixing the position of the actuator (430) together with the first guide structure (710). For example, the first shaft portion (422a) may include a protrusion configured to fix the position of the first actuator (431) together with the first guide portion (711) by protruding into the first guide groove (461a) of the first vibration plate (461). For example, the second shaft portion (422b) may include a protrusion configured to fix the position of the second actuator (432) together with the second guide portion (712) by protruding into the third guide groove (463a) of the third vibration plate (463). However, the embodiments supported in the present disclosure are not limited thereto.

[0162] Referring to FIG. 7B, in one embodiment, the electronic device (101) may include a second guide structure (720) for fixing the position of the actuator (430). The second guide structure (720) may fix the position of the actuator (430), for example, by occupying a space (S). For example, the second guide structure (720) may include a third guide portion (721) disposed between the first actuator (431) and the second actuator (432), a fourth guide portion (722) that fixes the position of the first actuator (431) together with the third guide portion (721), and a fifth guide portion (723) that fixes the position of the second actuator (432) together with the third guide portion (721). The third guide portion (721) may be interposed, for example, between the support plate (470) supporting the actuator (430) and the first support portion (214) of the housing (210) on which the head portion (421) is mounted. For example, the third guide portion (721) and the fourth guide portion (722) may be respectively coupled to both ends of the first piezoelectric element (441), thereby fixing the position of the first actuator (431) while the first actuator (431) provides haptic feedback. The third guide portion (721) and the fifth guide portion (723) may be respectively coupled to both ends of the second piezoelectric element (442), thereby fixing the position of the second actuator (432) while the second actuator (432) provides haptic feedback. However, the embodiments supported by the present disclosure are not limited thereto, and the electronic device (101) (or key button assembly (400)) may include various guide structures for aligning the actuator (430) with the shaft portion (422) (and / or sensor (450)).

[0163] According to the above-described embodiment, the electronic device (101) can improve the performance of haptic feedback provided from the actuator (430) through the key button (420) by including guide structures (710, 720) for fixing the position of the actuator (430) while the actuator (430) provides haptic feedback.

[0164] As described above, an electronic device (e.g., electronic device (101) of FIG. 1) may include a housing (e.g., housing (210) of FIG. 2a) including a recess (e.g., recess (410) of FIG. 4a). The electronic device may include a key button (e.g., one or more key buttons (320) of FIG. 3, key button (420) of FIG. 4a) including a head portion (e.g., head portion (421) of FIG. 4a) partially disposed within the recess and a shaft portion (e.g., shaft portion (422), first shaft portion (422a) or second shaft portion (422b) of FIG. 4a) extending from the head portion toward the interior of the electronic device. The electronic device may include a printed circuit board (e.g., printed circuit board (350) of FIG. 3) disposed within the housing toward the key button. The electronic device may include an actuator (e.g., actuator (430), first actuator (431), or second actuator (432) of FIG. 4A) disposed between the printed circuit board and the key button and configured to provide haptic feedback to the head portion based on pressure applied by the shaft portion. The electronic device may include a sensor (e.g., sensor (450), first sensor (451), or second sensor (452) of FIG. 4A) configured to detect the pressure. The printed circuit board may include a mounting portion (e.g., mounting portion (351) of FIG. 4a) on which the sensor is arranged and spaced apart from the actuator, and a deformable connecting portion (e.g., connecting portion (352), first connecting portion (352a) or second connecting portion (352b) of FIG. 4a) extending from the mounting portion to electrically connect the actuator and the mounting portion.

[0165] The recess may include a hole formed in an outer shell of the housing, through which the key button may be seated within the hole and extend into the interior of the electronic device.

[0166] The key button may include an outer portion at least partially disposed within the recess and an inner portion extending from the outer portion into the interior of the electronic device.

[0167] The printed circuit board may be arranged toward the key button such that when pressure is applied to an outer surface of the key button, the key button moves toward the printed circuit board.

[0168] The actuator may be configured to drive movement of the key button away from the printed circuit board when the actuator is activated. The actuator may be configured to drive movement of the key button outward when the actuator is activated. The actuator may be configured to drive movement of the key button in an alternating pattern when the actuator is activated. The actuator may be configured to provide vibration of the key button.

[0169] The sensor may be a switch that is activated when a force greater than a threshold force is applied to the sensor. Alternatively, the sensor may be configured to detect the degree of force applied to the sensor and provide a measurement thereof.

[0170] For example, the sensor may be aligned with the shaft portion so as to be pressed by the shaft portion.

[0171] For example, the electronic device may further include a support member (e.g., support member (510) of FIG. 5A) interposed between the mounting portion of the printed circuit board and the actuator to support the actuator. The actuator may include a first portion (e.g., first portion (430a) of FIG. 5A) attached on the support member, and a second portion (e.g., second portion (430b) of FIG. 5A) connected to the connecting portion of the printed circuit board and configured to deform based on the pressure.

[0172] For example, the housing may further include a through hole (e.g., one or more holes (310) of FIG. 3, a through hole (415) of FIG. 4a) connected to the recess and penetrated by the shaft portion. The electronic device may further include a waterproof member (e.g., a waterproof member (520) of FIG. 5a) configured to cover the through hole to isolate the inside from the outside of the electronic device and to be in contact with the second portion of the sensor and the actuator by the shaft portion.

[0173] For example, the electronic device may further include a guide member (e.g., guide member (540) of FIG. 5A) disposed between the mounting portion of the printed circuit board and the waterproof member. The guide member may be configured to support the waterproof member so that a force is applied to the waterproof member in a second direction opposite to the first direction, in order to limit a range of movement of the shaft portion in a first direction toward the interior of the electronic device from the head portion.

[0174] For example, the actuator may face one side of the mounting portion to which the sensor is coupled (e.g., the first side (451a) of FIG. 4A). The connecting portion may fold back on itself on the one side of the mounting portion so as to extend from the mounting portion to the actuator.

[0175] For example, the key button may further include another shaft portion (e.g., a second shaft portion (422b) of FIG. 4A) extending from the head portion toward the interior of the electronic device and spaced apart from the shaft portion (e.g., a first shaft portion (422a) of FIG. 4A). The actuator may be positioned between the shaft portion and the other shaft portion to provide haptic feedback to the head portion based on pressure applied by the other shaft portion. The electronic device may further include another sensor (e.g., a second sensor (452) of FIG. 4A) disposed on the seating portion to detect the pressure applied by the other shaft portion.

[0176] For example, the actuator may be aligned with the shaft portion and the sensor so as to be pressed by the shaft portion.

[0177] For example, the electronic device may further include a support plate attached to one side of the mounting portion facing the key button to support the actuator pressed by the shaft portion. The sensor may be attached to the other side of the mounting portion opposite to the one side (e.g., the second side (451b) of FIG. 4A).

[0178] For example, the actuator may include a piezoelectric element that provides the haptic feedback based on the pressure (e.g., a piezoelectric element (440) of FIG. 4A), and a vibration plate (e.g., a vibration plate (460) of FIG. 4A) coupled to the piezoelectric element to separate the piezoelectric element from the support plate and deformable based on the pressure. The connecting portion may connect a side of the piezoelectric element (e.g., a side (441c) or a side (442c) of FIG. 4A) that is separated from the support plate by the mounting portion and the vibration plate.

[0179] For example, the vibration plate may include a guide groove (e.g., guide grooves (462a, 464a) of FIG. 7A) that is sunken toward the piezoelectric element. The electronic device may include a first guide structure (e.g., first guide structure (710) of FIG. 7A) that is attached to one surface of the mounting portion and protrudes into the guide groove.

[0180] For example, the key button may further include another shaft portion extending from the head portion toward the interior of the electronic device and spaced apart from the shaft portion. The electronic device may further include another actuator (e.g., a second actuator (432) of FIG. 4A) spaced apart from the actuator (e.g., a first actuator (431) of FIG. 4A) disposed between the key button and the printed circuit board and configured to provide haptic feedback to the head portion based on pressure applied by the other shaft portion. The electronic device may further include another sensor (e.g., a second sensor (452) of FIG. 4A) disposed on the seating portion to detect the pressure applied by the other shaft portion.

[0181] For example, it may further include a second guide structure (e.g., the second guide structure (720) of FIG. 7b) disposed between the actuator and the other actuator.

[0182] For example, the key button may further include a hook portion extending from the head portion (e.g., the hook portion (425) of FIG. 4A). The hook portion may be coupled to the housing to prevent the key button from falling out of the recess of the housing.

[0183] For example, the housing may further include a support portion (e.g., a second support portion (215) of FIG. 4A) forming a space (S) for accommodating the printed circuit board.
