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).

For example, at least one sensor (230) may be attached to the frame (210) forming at least a portion of the key button (220). For example, the control unit (201) of the case (200) may be operatively coupled to at least one key button (220) via the at least one sensor (230). The control unit (201) may be configured to receive a user input via the at least one key button (220) that is partially exposed to the exterior of the case (200). For example, the at least one sensor (230) may detect a user input to a portion of at least one key button (220) that is exposed to the exterior of the case (200). The control unit (201) may be configured to control electronic components (e.g., at least one actuator (240)) within the case (200) based on the user input detected through the at least one sensor (230), or to transmit a signal corresponding to the user input to the electronic device (101) through the communication circuit (203). The operation of the control unit (201) through the at least one sensor (230) according to the type of the user input will be described below in FIG. 3A.

[0050] According to one embodiment, at least one key button (220) may be positioned along the periphery of the second portion (212) of the frame (210). For example, at least one key button (220) may be positioned on the side surface (23) of the electronic device (101) while the case (200) is coupled to the electronic device (101). For example, at least one key button (220) may be partially exposed through the second surface (210b) that surrounds a portion of the side surface (23) of the electronic device (101). For example, at least one key button (220) may be positioned at a position corresponding to a key button (25) positioned on the side surface (23) of the electronic device (101) while the electronic device (101) is housed in the case (200). The at least one key button (220) may perform a different function from the key button (25) of the electronic device (101) based on a user input to the at least one key button (220). For example, the position of the at least one key button (220) within the frame (210) may be changeable. For example, the at least one key button (220) may be positioned at a different position from the position corresponding to the key button (25) of the electronic device (101). For example, the at least one key button (220) may not overlap the key button (25) of the electronic device (101) when the second side (210b) of the second part (212) is viewed from above while the case (200) is worn on the electronic device (101).

[0051] Although it has been described that at least one key button (220) is arranged on the second face (210b) of the second portion (212) that at least partially surrounds the side (23) of the electronic device (101), this is exemplary, and the position at which the at least one key button (220) is arranged within the frame (210) is not limited. For example, the at least one key button (220) may be arranged on a third face (210c) of the second portion (212) that is spaced apart from the second face (210b) and faces in a direction opposite to the direction in which the second face (210b) faces. For example, the at least one key button (220) may be partially exposed to the outside of the case (200) through the third face (210c). For example, some of the at least one key button (220) may be arranged along the third face (210c). The remaining portion of the at least one key button (220) may be arranged along the second surface (210b). For example, the at least one key button (220) may be arranged on a surface that is opposite the first surface (210a) of the first portion (211) and is exposed to the outside of the case (200). However, the present invention is not limited thereto, and the at least one key button (220) may be arranged on a portion of the frame (210) that is exposed to the outside of the case (200).

For example, the at least one actuator (240) may be configured to vibrate. The at least one actuator (240) may vibrate to provide a haptic notification corresponding to the at least one key button (220) based on a user input via the at least one key button (220). For example, the control unit (201) can provide a haptic pattern to the case (200) through the at least one actuator (240) by adjusting the intensity and / or the period of vibration of the at least one actuator (240). The operation of the control unit (201) that provides the haptic pattern through the at least one actuator (240) will be described later with reference to FIG. 4. The case (200) can provide a variety of user experiences to the user by providing a haptic notification through the at least one actuator (240). According to one embodiment, the at least one actuator (240) may include, but is not limited to, at least one of a piezo actuator (240), a horizontal motor, a vertical motor, a vibration motor, a sound board, and a coil motor.

For example, one or more electronic components (e.g., control unit (201), memory (202), communication circuit (203), power management circuit (204)) of the case (200) may be mounted on the printed circuit board (260).

[0054] For example, a flexible printed circuit board (270) may extend from a printed circuit board (260) to at least one sensor (230). For example, the flexible printed circuit board (270) may include a first region (271) connected to the printed circuit board (260), a second region (272) connected to at least one sensor (230), and a third region (273) extending from the first region (271) to the second region (272). For example, the first region (271) and the third region (273) may be disposed within a first portion (211) of a frame (210). The second region (272) may be disposed within the second portion (212) for connection with at least one sensor (230) disposed within the second portion (212). For example, the second region (272) may be in contact with at least one sensor (230). For example, the third region (273) may be at least partially deformable. However, the present invention is not limited thereto. The case (200) may include a flexible printed circuit board (270) connecting the printed circuit board (260) and at least one key button (220), thereby providing a variety of user experiences to the user through the at least one key button (220).

[0055] According to one embodiment, the control unit (201) may be configured to identify a user input to at least one key button (220) detected through at least one sensor (230).

The control unit (201) may identify the user input to the at least one key button (220) based on the user's contact with the at least one key button (220). For example, the at least one sensor (230) may be configured to detect a pressure applied to the at least one key button (220). The control unit (201) may identify the user input to the at least one key button (220) based on identifying that the pressure applied to the at least one key button (220) is greater than or equal to a reference pressure. For example, at least one sensor (230) may be configured to detect a part of a user's body (e.g., a part of a body (30) of FIG. 3A) positioned on at least one key button (220). The at least one sensor (230) may be configured to detect a motion of the part of the user's body (30) on the at least one key button (220). The control unit (201) may identify the user input to the at least one key button (220) based on identifying that the motion of the part of the body (30) on the at least one key button (220) corresponds to a preset gesture. However, the above-mentioned embodiments are exemplary and are not limited thereto.

[0064] For example, the coil (205) may be connected to a printed circuit board (260). The coil (205) may be placed within a first portion (211) of a frame (210). The coil (205) may be placed between a first cover member (211a) and a second cover member (211b) of the first portion (211).

[0073] For example, referring to FIG. 3A, at least one touch sensor (231) can detect a contact of a part of a user's body (30) with at least one key button (220). The control unit (201) can identify a touch input to the at least one key button (220) based on the contact detected through the at least one touch sensor (231).

The at least one touch sensor (231) can be configured to detect a touch input to the at least one key button (220) based on receiving a portion of the light reflected from a part of the user's body (30) that has made contact with the at least one key button (220). For example, at least one sensor (230) may include an electrode disposed along a surface of at least one key button (220) exposed to the outside of the case (200). The at least one sensor (230) may be configured to detect a capacitance changed through the electrode based on a part of the user's body (30) that comes into contact with the at least one key button (220). The at least one key button (220) may be configured to detect a touch input to the at least one key button (220) based on detecting a change in the capacitance. The at least one touch sensor (231) may include at least one of a capacitive sensor and an ultrasonic sensor, but the above-mentioned embodiments are exemplary and not limited thereto.

[0074] For example, referring to FIG. 3B, at least one pressure sensor (232) can detect pressure applied to at least one key button (220) by a part of the user's body (30). For example, at least one key button (220) can be partially deformed by the pressure applied to the at least one key button (220).

The at least one pressure sensor (232) may be configured to detect a press input to the at least one key button (220) based on the resistance value being greater than or equal to a reference value. For example, the at least one pressure sensor (232) may include at least one of a strain gauge sensor and a force sensor, but the above-mentioned embodiments are exemplary and are not limited thereto.

[0075] Referring again to FIGS. 3A and 3B , at least one actuator (240) may be attached to at least one sensor (230). For example, at least one actuator (240) may be positioned below at least one key button (220). For example, at least one actuator (240) may be configured to vibrate at least one key button (220). For example, at least one actuator (240) may be configured to transmit vibration to at least one key button (220) based on a user input through the at least one key button (220). For example, the control unit (201) may provide a haptic notification to at least one key button (220) through at least one actuator (240) in response to a user input detected through the at least one sensor (230).

[0076] Referring to FIGS. 3c and 3d, the control unit (201) of the case (200) can identify a user's motion on at least one key button (220) detected through at least one sensor (230). Based on identifying that the motion corresponds to a gesture belonging to a preset gesture group, the control unit (201) can transmit a signal for performing a function of the electronic device (101) corresponding to the gesture to the electronic device (101) through the communication circuit (203). For example, at least one sensor (230) can be configured to detect a user's motion on at least one key button (220) based on a touch input on the at least one key button (220). For example, the control unit (201) may, based on identifying a user's motion detected through at least one sensor (230), cause execution of a function corresponding to the motion on at least one key button (220) of an electronic device (101) connected to the case (200).

[0077] For example, referring to FIG. 3C, the control unit (201) may cause the electronic device (101) to execute a function corresponding to the motion (311) on the first key button (221) based on identifying a user's motion (311) in a first direction (301) on the first key button (221).

For example, the control unit (201) may cause the electronic device (101) to execute a function corresponding to the motion (321) on the second key button (222) based on identifying a user's motion (321) in a first direction (301) on the second key button (222). The control unit (201) may cause the electronic device (101) to execute a function corresponding to the motion (322) on the second key button (222) based on identifying a user's motion (322) in a second direction (302) opposite to the first direction (301) on the second key button (222).

[0078] For example, referring to FIG. 3D, the control unit (201) may cause the electronic device (101) to execute a function corresponding to the motion (313) on the first key button (221) based on identifying a user's motion (313) in a third direction (303) perpendicular to the first direction (301) on the first key button (221). The control unit (201) may cause the electronic device (101) to execute a function corresponding to the motion (314) on the first key button (221) based on identifying a user's motion (314) in a fourth direction (304) opposite to the third direction (303) on the first key button (221). For example, the control unit (201) may cause the electronic device (101) to execute a function corresponding to the motion (323) on the second key button (222) based on identifying a user's motion (323) in a third direction (303) on the second key button (222). The control unit (201) may cause the electronic device (101) to execute a function corresponding to the motion (324) on the second key button (222) based on identifying a user's motion (324) in a fourth direction (304) opposite to the third direction (303) on the second key button (222). However, the embodiments described above are exemplary and are not limited thereto, and the control unit (201) may cause the electronic device (101) to perform functions of the electronic device (101) corresponding to each of the motions, based on identifying user's motions in various directions.

[0079] According to the above-described embodiment, the case (200) can provide a variety of user experiences to the user by causing the electronic device (101) connected to the case (200) to execute functions based on various types of user input detected through at least one sensor (230). The case (200) can provide a variety of user experiences to the user through at least one key button (220) by including at least one actuator (240) attached to the at least one sensor (230).

[0080] Figure 4 illustrates key buttons of an exemplary case for providing a haptic pattern.

[0081] Referring to FIG. 4, a case (200) for an electronic device (101) may include a control unit (e.g., a control unit (201) of FIG. 2B), a memory for storing instructions (e.g., a memory (202) of FIG. 2B), and a communication circuit (e.g., a communication circuit (203) of FIG. 2B). The case (200) may include a frame (210) for storing the electronic device (101), which includes at least one key button (220) that is partially exposed to the outside of the case (200) and includes at least one sensor (e.g., at least one sensor (230) of FIG. 2B). The case (200) may include at least one actuator (e.g., at least one actuator (240) of FIG. 2B) disposed inside the frame (210). The control unit (201) may be configured to identify a user input to the at least one key button (220) detected through the at least one sensor (230). The control unit (201) may be configured to transmit a signal for performing a function of the electronic device (101) corresponding to the user input to the electronic device (101) through the communication circuit (203) based on the identified user input, and to vibrate the at least one actuator (240).

[0082] According to one embodiment, the control unit (201) may provide haptic patterns (400) corresponding to the performance of a function of the electronic device (101) through at least one actuator (240) based on a signal related to the performance of the function of the electronic device (101) received from the electronic device (101) through the communication circuit (203). According to one embodiment, the haptic patterns (400) may be provided through at least one key button (220) by at least one actuator (240) attached to at least one sensor (230).

[0083] For example, the control unit (201) may provide a haptic pattern (401) through at least one key button (220) based on receiving a signal for turning on the electronic device (101) and / or switching an application. For example, the control unit (201) may provide a haptic pattern (402) through at least one key button (220) based on receiving a signal related to an error and / or failure in the execution of a function of the electronic device (101). For example, the control unit (201) may provide a haptic pattern (403) through at least one key button (220) based on receiving a signal for inducing the execution of an application of the electronic device (101) and / or temporarily suspending the application. For example, the control unit (201) may provide a haptic pattern (404) through at least one key button (220) based on receiving a signal for notifying that the termination of an application of the electronic device (101) is imminent. For example, the control unit (201) may provide a haptic pattern (405) and / or a haptic pattern (407) through at least one key button (220) while a touch input and / or a press input to the at least one key button (220) is identified. For example, the control unit (201) may provide a haptic pattern (406) through at least one key button (220) based on receiving a signal for turning off and / or terminating the electronic device (101). For example, the control unit (201) may provide a haptic pattern (408) through at least one key button (220) based on receiving a signal for preparation and / or confirmation of application execution of the electronic device (101). However, the haptic patterns (400) described above are exemplary, and the case (200) may provide various haptic patterns including the haptic patterns (400) through at least one actuator (240) (or at least one key button (220)).

[0084] According to the above-described embodiment, the case (200) for the electronic device (101) can provide various user experiences to the user by providing various haptic patterns through at least one actuator (240) and / or at least one key button (220).

[0085] Figures 5a, 5b, 5c, 5d, and 5e illustrate exemplary cases for electronic devices.

[0086] Referring to FIGS. 5A, 5B, 5C, 5D, and 5E, a case (200) for an electronic device (101) may include a control unit (e.g., a control unit (201) of FIG. 2B), a memory (e.g., a memory (202) of FIG. 2B) for storing instructions, and a communication circuit (e.g., a communication circuit (203) of FIG. 2B). The case (200) may include a frame (210) for storing the electronic device (101), the frame (210) including at least one key button (220) that is partially exposed to the outside of the case (200) and includes at least one sensor (e.g., at least one sensor (230) of FIG. 2B). The case (200) may include at least one actuator (e.g., at least one actuator (240) of FIG. 2B) disposed inside the frame (210). The control unit (201) may be configured to identify a user input to the at least one key button (220) detected through the at least one sensor (230). The control unit (201) may be configured to transmit a signal for performing a function of the electronic device (101) corresponding to the user input to the electronic device (101) through the communication circuit (203) based on the identified user input, and to vibrate the at least one actuator (240). According to one embodiment, the frame (210) may include a first part (211) that surrounds the back surface (22) of the electronic device (101) housed in the case (200), and a second part (212) that extends from the first part (211) and at least partially surrounds the side surface (23) of the electronic device (101). At least one key button (220) may be positioned along the edge of the second portion (212).

[0087] According to one embodiment, at least one key button (220) may include first key buttons (530) arranged on a first edge part (511) of the second portion (212), and one or more second key buttons (540) arranged on at least one of the two ends (511a, 511b) of the first edge part (511).

[0088] For example, the second portion (212) may include a first edge part (511), a second edge part (512) spaced apart from the first edge part (511) and facing the first edge part (511), a third edge part (513) extending from the first edge part (511) to the second edge part (512), and a fourth edge part (514) facing the third edge part (513) and spaced apart from the third edge part (513). The first key buttons (530) may be arranged along the first edge part (511) among the edge parts (511, 512, 513, 514). For example, the first key buttons (530) may be partially exposed to the outside of the case (220) through the second surface (210b) of the first edge part (511). The above first key buttons (530) may be partially placed inside the first edge part (511).

[0089] For example, one end (511a) of the first edge part (511) may be a portion connecting the first edge part (511) and the third edge part (513). The other end (511b) of the first edge part (511), opposite to the one end (511a), may be a portion connecting the first edge part (511) and the fourth edge part (514). For example, both ends (511a, 511b) of the first edge part (511) may have a curvature by being bent. For example, one or more second key buttons (540) may be arranged along both ends (511a, 511b) of the first edge part (511). For example, one or more second key buttons (540) may be arranged around both ends (511a, 511b) of the first edge part (511). For example, some of the one or more second key buttons (540) may cause a function (e.g., taking a picture) of a camera (not shown) of an electronic device (101) connected to the case (200) to be executed based on a user input to the one or more second key buttons (540). For example, referring to FIG. 5C, a fourth key button (541) arranged at one end (511a) of the first edge part (511) among the one or more second key buttons (540) may come into contact with a part (30) of the user's body. Among the one or more second key buttons (540), the fifth key button (542) disposed on the other end (511b) of the first edge part (511) may be brought into contact with another part (50) of the user's body. Based on receiving a signal related to an application (e.g., a game application) within the electronic device (101) connected to the case (200), the one or more second key buttons (540) may provide various haptic patterns related to the application to the user's body parts (30, 50) through at least one actuator (240).

[0090] Although it has been described that at least one key button (220) is arranged along the first edge part (511), the above-mentioned embodiments are exemplary and are not limited thereto. At least one key button (220) may be arranged on at least some of the edge parts (511, 512, 513, 514) of the second part (212).

[0091] Referring to FIG. 5D, at least one key button (220) may be arranged along the first edge part (511). The at least one key button (220) may, for example, cause a function of a camera of an electronic device (101) mounted within the case (200) to be executed by the user while the case (200) is gripped by the user. For example, the at least one key button (220) may cause a camera of an electronic device (101) connected to the case (200) to take a picture by pressing the body part (50) of the user.

[0092] Referring to FIG. 5e, the second part (212) may include a groove (520) formed on a first edge part (511) of the second part (212) to expose a key button (e.g., a key button (25) of FIG. 6b) of the electronic device (101) on the side surface (23) of the electronic device (101) to the outside of the case (200). At least one key button (220) may include one or more third key buttons (550) arranged along a second edge part (512) facing the first edge part (511) of the second part (212). For example, the groove (520) may expose the key button (25) of the electronic device (101) to the outside of the case (200) while the electronic device (101) is coupled to the case (200). For example, the home (520) may be formed at a position corresponding to the position of the key button (25) of the electronic device (101) while the electronic device (101) is stored in the case (200). For example, one or more third key buttons (550) may face the home (520) and be spaced apart from the home (520). For example, one or more third key buttons (550) may cause execution of a function of the electronic device (101) that is different from the function of the key button (25) of the electronic device (101). For example, one or more third key buttons (550) may cause execution of at least one application within the electronic device (101) connected to the case (200), based on a user input to the one or more third key buttons (550), but is not limited thereto.

[0093] According to the above-described embodiment, the case (200) for the electronic device (101) can provide a variety of user experiences to the user by including at least one key button (220) arranged at various locations of the frame (210).

[0094] Figures 6a, 6b, and 6c illustrate exemplary cases for electronic devices.

[0095] Referring to FIGS. 6A, 6B, and 6C, a case (200) for an electronic device (101) may include a control unit (e.g., a control unit (201) of FIG. 2B), a memory for storing instructions (e.g., a memory (202) of FIG. 2B), and a communication circuit (e.g., a communication circuit (203) of FIG. 2B). The case (200) may include a frame (210) for storing the electronic device (101), the frame (210) including at least one key button (220) that is partially exposed to the outside of the case (200) and includes at least one sensor (e.g., at least one sensor (230) of FIG. 2B). The case (200) may include at least one actuator (e.g., at least one actuator (240) of FIG. 2B) disposed inside the frame (210). The control unit (201) may be configured to identify a user input to the at least one key button (220) detected through the at least one sensor (230). The control unit (201) may be configured to transmit a signal for performing a function of the electronic device (101) corresponding to the user input to the electronic device (101) through the communication circuit (203) based on the identified user input, and to vibrate the at least one actuator (240).

[0096] According to one embodiment, at least one key button (220) may be positioned at a different position from a position corresponding to a key button (25) of the electronic device (101) while the electronic device (101) is coupled to the case (200). For example, the at least one key button (220) may not overlap with the key button (25) of the electronic device (101) when the at least one key button (220) is viewed from above while the electronic device (101) is housed within the case (200). The case (200) may, through communication with the electronic device (101), cause a function of the electronic device (101) that is different from a key button (25) of the electronic device (101) through the at least one key button (220).

[0097] According to one embodiment, the control unit (201) of the case (200) may transmit a signal for deactivating the key button (25) of the electronic device (101) through the communication circuit (203) based on identifying the connection between the case (200) and the electronic device (101). The processor (e.g., the processor (120) of FIG. 1) of the electronic device (101) may deactivate the key button (25) based on receiving the signal for deactivation. For example, while the electronic device (101) is stored in the case (200), the key button (25) of the electronic device (101) may be covered by the frame (210) of the case (200). The processor (120) of the electronic device (101) can deactivate the key button (25) based on identifying the combination of the case (200) and the electronic device (101). The processor (120) can transmit a signal for activating at least one key button (220) to the case (200) based on identifying the combination of the case (200) and the electronic device (101). The at least one key button (220) of the case (200) can supply power to the at least one key button (220) through a power management circuit (e.g., the power management circuit (204) of FIG. 2B) based on receiving the signal for activating the at least one key button (220).

[0098] According to one embodiment, the frame (210) of the case (200) may include a third portion (620) for connection with a connector (207) of the case (200), and an opening (610) for receiving the third portion (620). For example, the connector (207) may be connected to a printed circuit board (e.g., a printed circuit board (260) of FIG. 2C) and / or a battery (e.g., a battery (206) of FIG. 2B) through a portion of a flexible printed circuit board (e.g., a flexible printed circuit board (270) of FIG. 2C) within the third portion (620). For example, the connector (207) may be positioned at a position corresponding to a connection terminal (e.g., a connection terminal (178) of FIG. 1) of the electronic device (101) while the electronic device (101) is housed within the case (200). The connector (207) can supply power from the electronic device (101) to the battery (206) by being connected to the connection terminal (178). For example, the opening (610) can have a shape corresponding to the third portion (620). For example, the opening (610) and the third portion (620) can be arranged in the second portion (212) of the frame (210). The connector (207) can be arranged so as to protrude from the third portion (620) toward the connection terminal (178) of the electronic device (101) while the case (200) is coupled with the electronic device (101).

[0099] According to one embodiment, the case (200) may include a connector (207) that protrudes from the frame (210) and includes conductive portions (630) for connection with the electronic device (101). For example, the conductive portions (630) may be connected to a battery (206) within the case (200). The conductive portions (630) may be in contact with a connection portion (26) formed on a back surface (22) of the electronic device (101) while the electronic device (101) is housed within the case (200). The conductive portions (630) may supply power from the electronic device (101) to the battery (206) by being in contact with the connection portion (26). The conductive portions (630) may be referred to as, but are not limited to, pogo pins and / or contacts.

[0100] According to the above-described embodiment, the case (200) includes a connector (207) configured to receive power from the electronic device (101) by being connected to the connection terminal (178) and / or the connection portion (26) of the electronic device (101), thereby allowing power for driving the case (200) to be provided from the electronic device (101).

[0101] Figures 7a and 7b are flow charts showing the operation of an exemplary case.

[0102] The operations of FIGS. 7A and 7B can be performed by a control unit (e.g., a control unit (201) of FIG. 2B) of a case (e.g., a case (200) of FIG. 2A) for an electronic device (e.g., an electronic device (101) of FIG. 1).

[0103] Referring to FIG. 7A, in operation (701), the control unit (201) of the case (200) may receive a signal from the electronic device (101) for connecting the case (200) and the electronic device (101). For example, a processor (e.g., the processor (120) of FIG. 1) in the electronic device (101) may transmit a signal for connecting the case (200) and the electronic device (101) to the case (200) based on a change in magnetic force detected from at least one Hall sensor by interaction between at least one Hall sensor in the electronic device (101) and at least one magnet (e.g., at least one magnet (250) of FIG. 2B) in the case (200). The above control unit (201) can receive a signal for the connection caused by at least one magnet (250) through a communication circuit (e.g., the communication circuit (203) of FIG. 2b).

[0104] In operation (703), the control unit (201) of the case (200) can transmit a signal for authentication of the case (200) to the electronic device (101). For example, the case (200) can transmit authentication information of the case (200) to the electronic device (101) through the communication circuit (203) based on receiving a signal for connection between the electronic device (101) and the case (200) from the electronic device (101).

[0105] In operation (705), the control unit (201) of the case (200) can identify whether the electronic device (101) and the case (200) are connected. For example, the control unit (201) can identify the connection between the electronic device (101) and the case (200) based on a user input for connection between the electronic device (101) and the case (200) received from the electronic device (101) through the communication circuit (203). For example, the control unit (201) can identify the connection between the electronic device (101) and the case (200) based on identifying power provided from the electronic device (101) through a coil (e.g., coil (205) of FIG. 2B). The control unit (201) may perform operation (705) if it fails to identify the connection between the electronic device (101) and the case (200) (e.g., 705-No).

[0106] In operation (707), the control unit (201) of the case (200) can transmit a signal to the electronic device (101) for deactivating a key button (e.g., key button (25) of FIG. 6B) of the electronic device (101). For example, the case (200) can transmit a signal to the electronic device (101) for deactivating the key button (25) of the electronic device (101) based on identifying a connection between the electronic device (101) and the case (200). The processor (120) of the electronic device (101) can deactivate the key button (25) based on receiving the signal for deactivation.

[0107] In operation (709), the control unit (201) of the case (200) can identify whether a user input has been input by at least one key button (e.g., at least one key button (220) of FIG. 2a). For example, the control unit (201) can identify a user input detected through at least one sensor (e.g., at least one sensor (230) of FIG. 2b). For example, the control unit (201) can identify a user input through at least one touch input detected through at least one touch sensor (e.g., at least one touch sensor (231) of FIG. 2b). For example, the control unit (201) can identify a user input through at least one press input detected through at least one pressure sensor (e.g., at least one pressure sensor (232) of FIG. 2b). The above control unit (201) can perform operation (709) if it fails to identify the user input to the at least one key button (220) (e.g., 709-No).

[0108] In operation (711), the control unit (201) of the case (200) may be configured to vibrate at least one actuator (e.g., at least one actuator (240) of FIG. 2B). For example, the control unit (201) may vibrate at least one actuator (240) based on identifying a user input to at least one key button (220). For example, the control unit (201) may provide a haptic notification and / or a haptic pattern through the at least one key button (220) by vibrating at least one actuator (240) attached to the at least one key button (220).

[0109] In operation (713), the control unit (201) of the case (200) can transmit a signal for performing a function of the electronic device (101) corresponding to a user input to at least one key button (220) to the electronic device (101). For example, the control unit (201) can transmit a signal for performing a function of the electronic device (101) corresponding to the user input based on the user input entered through at least one key button (220) to the electronic device (101) through the communication circuit (203). For example, the control unit (201) can transmit a signal for performing a function of the electronic device (101) corresponding to at least one touch input detected through at least one touch sensor (231) to the electronic device (101) through the communication circuit (203). For example, the control unit (201) can transmit a signal for executing a function of the electronic device (101) corresponding to at least one press input detected through at least one pressure sensor (232) to the electronic device (101) through the communication circuit (203).

[0110] Referring to FIG. 7B, in operation (715), the control unit (201) of the case (200) can charge the battery (e.g., the battery (206) of FIG. 2B) from the electronic device (101) through the coil (e.g., the coil (205) of FIG. 2B). For example, the control unit (201) can control the power management circuit (e.g., the power management circuit (204) of FIG. 2B) to charge the battery (206) from the electronic device (101) through the coil (205) based on identifying the connection between the case (200) and the electronic device (101).

[0111] In operation (717), the control unit (201) may supply power to at least one sensor (230) through the power management circuit (204). For example, the control unit (201) may control the power management circuit (204) to supply power from the battery (206) of the case (200) to at least one sensor (230) based on the connection between the electronic device (101) and the case (200). The at least one sensor (230) may operate to detect a user input to at least one key button (220) by receiving the power.

[0112] In operation (719), the control unit (201) of the case (200) can identify whether the amount of power charged in the battery (206) is less than a reference value. For example, the control unit (201) of the case (200) can identify whether the amount of power charged in the battery (206) is less than a reference value based on identifying the connection between the electronic device (101) and the case (200). While identifying the amount of power as being less than the reference value (e.g., 719-Yes), the control unit (201) can perform operation (715).
