[0133] According to one embodiment, the electronic device (300) may include a pressure sensor (361), a pressure sensor (362), and / or a switch (363).

For example, the pressure sensors (361, 362) may be configured to identify a pressure input based on the pressure applied to the button (310, 320).

[0135] According to one embodiment, the electronic device (300) may include a piezo actuator (370). The piezo actuator (370) may be used to convert an electrical signal into vibration. Vibration may be referred to as a mechanical stimulus that a user can perceive through tactile or kinesthetic senses. The piezo actuator (370) may be referred to as a device capable of transmitting mechanical stimulus through a medium, not limited to a device that simply generates vibration.

[0136] According to one embodiment, the piezo actuator (370) can be used to identify pressure as well as vibration output. For example, the piezo actuator (370) may operate based on the converse piezoelectric effect. The piezo actuator (370) may also operate based on the piezoelectric effect. Thus, when pressure is applied to the piezo actuator (370), a voltage may be generated between the terminals of the piezo actuator (370). The electronic device (300) (or processor (380)) can identify that pressure has been applied to the piezo actuator (370) based on the voltage difference between the terminals of the piezo actuator (370).

[0137] For example, the piezo actuator (370) may include a first terminal and a second terminal. The processor (380) may apply a voltage between the first terminal and the second terminal using a piezo actuator management circuit (375). Based on applying a voltage between the first terminal and the second terminal, the processor (380) may output vibration through the piezo actuator (370).

[0138] For example, when pressure is applied to the piezo actuator (370), the voltage difference between the first terminal and the second terminal may be within the reference voltage range. When pressure is not applied to the piezo actuator (370), the voltage difference between the first terminal and the second terminal may be outside the reference voltage range. The processor (380) can identify whether pressure is applied to the piezo actuator (370) based on the voltage difference between the first terminal and the second terminal.

[0139] In the following description, an example of using a piezo actuator (370) for the output of vibration as well as for identifying pressure will be described.

[0140] According to one embodiment, the electronic device (300) may include a piezo actuator management circuit (375).

The piezo actuator management circuit (375) may be connected to the piezo actuator (370) based on a signal line for driving the piezo actuator (370). For example, the piezo actuator management circuit (375) may drive the piezo actuator (370) based on applying a voltage between the first terminal and the second terminal of the piezo actuator (370).

[0141] According to one embodiment, the electronic device (300) may include a memory (390). The memory (390) may be used to store information or data. For example, the memory (390) may correspond to the memory (130) of FIG. 1. For example, the memory (390) may be a volatile memory unit or units. For example, the memory (390) may be a non-volatile memory unit or units. For example, the memory (390) may be a computer-readable medium of another form, such as a magnetic or optical disk. For example, the memory (390) may store data acquired based on an operation performed by the processor (380) (e.g., an algorithm execution operation). According to an embodiment, the memory (390) may be configured to be integrated with the processor (380).

[0142] According to one embodiment, within the memory (390), one or more instructions (or commands) representing operations and / or operations to be performed on data by the processor (380) of the electronic device (300) may be stored.

Hereinafter, the term "application installed in the electronic device (e.g., electronic device (300))" may be referred to as one or more instructions provided in the form of an application being stored in the memory, and said one or more applications being stored in an executable format (e.g., a file having an extension specified by the operating system of the electronic device (300)) by the processor of the electronic device. According to one embodiment, the electronic device (300) may execute one or more instructions stored in the memory to perform the operations of the electronic device (300) described below. For example, when executed by the processor (380), one or more of the above instructions may cause the electronic device (300) to perform at least some of the operations of the electronic device (300) described below.

[0143] According to one embodiment, the electronic device (300) may include a power management circuit (395).

For example, the power management circuit (395) may be referred to as a power management integrated circuit (PMIC). The power management circuit (395) may be used to obtain charge state information (e.g., lifespan, overvoltage, undervoltage, overcurrent, overcharge, overdischarge, overheating, short circuit, or swelling) related to the charging of the battery of the electronic device (300). For example, the power management circuit (395) may be used for the operation of a piezo actuator (370). The power management circuit (395) may provide voltage (or power) for driving the piezo actuator (370).

[0144] In the following FIGS. 6, 7a, and 7b, examples of signals provided within an electronic device will be specifically described.

[0145] FIG. 6 illustrates an example of the operation of an electronic device according to one embodiment.

[0146] Referring to FIG. 6, the electronic device (300) may include the components shown in FIG. 5. For example, the electronic device (300) may further include a microcontroller unit (MCU) (600) (e.g., an MCU including various circuits). For example, the MCU (600) may be used to manage a pressure sensor (361), a pressure sensor (362), a switch (363), and / or a piezo actuator (370).

[0147] For example, the pressure sensor (361) may provide a signal to the MCU (600) indicating that pressure on the button (310) has been identified. The MCU (600) may provide a signal to the processor (380) indicating that pressure on the button (310) has been identified. Based on the signal received from the MCU (600), the processor (380) may execute a function assigned to the pressure on the button (310).

[0148] For example, the pressure sensor (362) may provide a signal to the MCU (600) indicating that pressure on the button (320) has been identified. The MCU (600) may provide a signal to the processor (380) indicating that pressure on the button (320) has been identified. Based on the signal received from the MCU (600), the processor (380) may execute a function assigned to the pressure on the button (320).

[0149] For example, the switch (363) may provide a signal to the MCU (600) indicating that an input to the button (330) has been identified. The MCU (600) may provide a signal to the processor (380) indicating that an input to the button (330) has been identified. Based on the signal received from the MCU (600), the processor (380) may execute a function assigned to the input to the button (330).

[0150] According to one embodiment, the processor (380) may output vibration through the piezo actuator (370) based on identifying pressure on the button (310) and / or button (320). The processor (380) may provide (or transmit) a signal to the MCU (600) to instruct it to output vibration through the piezo actuator (370). The MCU (600) may provide (or transmit) a signal to the piezo actuator management circuit (375) to instruct it to output vibration through the piezo actuator (370). The piezo actuator management circuit (375) may apply a voltage to the piezo actuator (370) to output vibration based on the signal. For example, power for the voltage to output vibration may be provided from the power management circuit (375).

[0151] According to one embodiment, based on pressure on the button (310) and / or button (320), the voltage difference between the first terminal and the second terminal of the piezo actuator (370) may be changed to within a reference voltage range. The piezo actuator management circuit (375) may identify that the voltage difference between the first terminal and the second terminal has been changed to within a reference voltage range. The piezo actuator management circuit (375) may provide a signal to the MCU (600) indicating that the voltage difference between the first terminal and the second terminal has been changed to within a reference voltage range. According to an embodiment, the signal may also indicate that pressure has been applied to the button (310) and / or button (320). The MCU (600) may provide a signal to the processor (380) indicating that the voltage difference between the first terminal and the second terminal has been changed to within a reference voltage range. The processor (380) can identify that pressure is applied to the button (310) and / or button (320) based on the acquired signal. The processor (380) can perform the function assigned to the pressure on the button (310) and / or button (320). For example, if the function assigned to the pressure on the button (310) and / or button (320) is related to the power management circuit (395), the processor (380) can provide the power management circuit (395) with a control signal to perform the said function.

[0152] The electronic device (300) illustrated in FIG. 6 may include an MCU (600) for controlling a pressure sensor (361), a pressure sensor (362), a switch (363), and / or a piezo actuator (370). However, if a malfunction occurs in the pressure sensor (361), the pressure sensor (362), the switch (363), and / or the MCU (600), the processor (380) may not be able to identify whether pressure (or input) has been applied to the button (310), the button (320), and / or the button (330).

[0153] For example, if pressure on the button (310) and button (320) is maintained for a reference time, a reset of the electronic device (300) may be performed. For example, if a malfunction occurs in the pressure sensor (361) (or pressure sensor (362)) and / or MCU (600), a reset of the electronic device (300) may not be performed. To prevent and / or reduce the malfunction of the MCU (600), the electronic device (300) may not include the MCU (600). Additionally, since the piezo actuator (370) can identify pressure on the button (310), if a malfunction occurs in the pressure sensor (361) for the button (310), the processor (380) can identify whether pressure has been applied to the button (310) through the piezo actuator (370). Accordingly, in FIGS. 7a and 7b, an example for determining whether pressure has been applied to a button (310) using a piezo actuator (370) by an electronic device (300) that does not include an MCU (600) will be described in more detail.

[0154] FIG. 7a illustrates an example of the operation of an electronic device according to one embodiment.

[0155] FIG. 7b illustrates an example of the operation of an electronic device according to one embodiment.

[0156] Referring to FIGS. 7a and 7b, the pressure sensor (361) may be connected (indirectly or directly) to the processor (380). The pressure sensor (362) may be connected (indirectly or directly) to the processor (380). The switch (363) may be connected (indirectly or directly) to the processor (380). For example, the pressure sensor (361), the pressure sensor (362), and the switch (363) may each be connected via the general-purpose input / output (GPIO) of the processor (380).

[0157] For example, the processor (380) can identify a malfunction of the pressure sensor (361) (or pressure sensor (362), switch (363)) based on identifying that no signal is received from the pressure sensor (361) (or pressure sensor (362), switch (363)). For example, the processor (380) can identify a malfunction of the pressure sensor (361) (or pressure sensor (362), switch (363)) based on identifying that no ID (identifier) ​​register value is output from the pressure sensor (361). For example, the processor (380) can identify a malfunction of the pressure sensor (361) (or pressure sensor (362), switch (363)) based on identifying that I2C (inter-integrated circuit) communication with the analogue frontend corresponding to the pressure sensor (361) (or pressure sensor (362), switch (363)) is not performed.

[0158] According to one embodiment, the pressure sensor (361) may be configured to provide a first signal to the processor (380) based on pressure on the button (310). For example, the first signal may indicate pressure on the button (310). The piezo actuator (370) may be configured to transmit a second signal to the processor (380) based on pressure on the button (310) and / or the button (320). For example, the second signal may indicate pressure on the button (310) and / or the button (320). The switch (363) may be configured to provide a third signal to the processor (380) based on input to the button (330). For example, the third signal may indicate input to the button (330). The pressure sensor (362) may be configured to provide a fourth signal to the processor (380) based on pressure on the button (320). For example, the fourth signal can indicate pressure on the button (320).

[0159] If the electronic device (300) does not include an MCU (e.g., the MCU (600) of FIG. 6), it is possible to prevent malfunction of the pressure sensor (361, 362) or switch (363) due to malfunction of the MCU. For example, the processor (380) may perform at least some or all of the functions of the MCU (600) of FIG. 6. Although not illustrated, the processor (380) may include an auxiliary processor (e.g., the auxiliary processor (382) of FIG. 11) for performing the functions of the MCU (600) of FIG. 6.

[0160] Referring to FIG. 7a, the piezo actuator (370) may be connected to the processor (380) through the piezo actuator management circuit (375). For example, the processor (380) may be connected to the piezo actuator (370) through the piezo actuator management circuit (375) to output vibration through the piezo actuator (370). The piezo actuator (370) may be connected to the processor (380) to provide (or transmit, output) a second signal to the processor (380) indicating that pressure on the button (310) and / or button (320) is identified.

[0161] For example, for the output of vibration, the piezo actuator (370) may be connected to the processor (380) via the piezo actuator management circuit (375). For the identification of pressure, the piezo actuator (370) may be connected to the processor (380). For the identification of pressure, the piezo actuator (370) may be connected to the processor (380) without the piezo actuator management circuit (375).

[0162] According to one embodiment, the processor (380) can detect a malfunction related to the button (310) based on receiving a second signal from the piezo actuator (370) while the first signal is not provided from the pressure sensor (361). The processor (380) can execute a function assigned to a combination of pressure on the button (310) and pressure on the button (330) in response to the second signal and the third signal being maintained for a reference time. The function assigned to the combination of pressure on the button (310) and pressure on the button (330) may be related to a reset of the electronic device (300). For example, the processor (380) can perform a reset of the electronic device (300) based on the pressure on the button (310) and the button (330) being maintained for a reference time. Based on detecting a malfunction related to the button (310), the processor (380) can execute a function assigned to a combination of pressure on the button (310) and pressure on the button (330) in response to the second signal and the third signal being maintained for a reference time.

[0163] For example, the processor (380) can use the power management circuit (395) to execute a function assigned to a combination of pressure on the button (310) and pressure on the button (330). The processor (380) can control the power management circuit (395) to execute the said function.

[0164] Referring to FIG. 7b, the piezo actuator (370) can be connected to the processor (380) through the piezo actuator management circuit (375). The piezo actuator (370) can be connected to the processor (380) through the control circuit (750).

[0165] For example, to output vibration through the piezo actuator (370), the processor (380) may be connected to the piezo actuator (370) through a piezo actuator management circuit (375). The piezo actuator (370) may be connected to the processor (380) through a control circuit (750) to provide (or transmit, output) a second signal to the processor (380) indicating that pressure on the button (310) and / or button (320) has been identified.

[0166] According to one embodiment, the control circuit (750) can detect a malfunction related to the button (310) based on receiving a second signal from the piezo actuator (370) while the first signal is not provided from the pressure sensor (361) to the processor (380). Although not illustrated, a third signal may be provided from the switch (363) to the power management circuit (395).

[0167] For example, the control circuit (750) can identify that a second signal provided from the piezo actuator (370) is maintained for a reference time (e.g., 7 seconds) based on detecting a malfunction related to the button (310). The control circuit (750) can provide a signal to the power management circuit (395) indicating that the second signal has been maintained for the reference time.

[0168] The power management circuit (395) can identify that the third signal provided from the switch (363) is maintained for a reference time. The power management circuit (395) can perform a reset of the electronic device (300) in response to receiving a signal indicating that the second signal is maintained for a reference time.

[0169] For example, the control circuit (750) may detect a malfunction of the button (310) and provide a signal to the power management circuit (395) indicating that the second signal has been maintained for a reference time. Thus, even if a malfunction (or non-operation) of the processor (380) of the electronic device (300) occurs, the electronic device (300) may be reset.

[0170] According to an embodiment, when the processor (380) is operating normally, the processor (380) may receive a first signal from a pressure sensor (361) based on pressure on the button (310). The processor (380) may provide the first signal to a control circuit (750). The control circuit (750) may identify that the first signal provided by the processor (380) is maintained for a reference time (e.g., 7 seconds). The control circuit (750) may provide a signal to a power management circuit (395) indicating that the first signal has been maintained for the reference time. The power management circuit (395) may identify that a third signal provided by the switch (363) is maintained for the reference time. In response to receiving a signal indicating that the first signal has been maintained for the reference time, the power management circuit (395) may perform a reset of the electronic device (300).

[0171] According to an embodiment, the control circuit (750) may receive a first signal from the processor (380). The control circuit (750) may receive a second signal from the piezo actuator (370). The control circuit (750) may identify that at least one of the first signal and the second signal is maintained for a reference time. The control circuit (750) may provide a signal to the power management circuit (395) indicating that at least one of the first signal and the second signal is maintained for a reference time.

[0172] The power management circuit (395) can identify that the third signal provided from the switch (363) is maintained for a reference time. The power management circuit (395) can perform a reset of the electronic device (300) in response to receiving a signal indicating that at least one of the first signal and the second signal has been maintained for a reference time.

[0173] Hereinafter, for convenience of explanation, the operation of providing a second signal from a piezo actuator (370) to a processor (380) in the electronic device (300) illustrated in FIG. 7a will be described in detail. The example described below is not limited to the electronic device (300) illustrated in FIG. 7a and may also be applied to the electronic device (300) illustrated in FIG. 6 or FIG. 7b.

[0174] FIG. 8 illustrates an example of an operation in which a second signal is provided from a piezo actuator to a processor according to one embodiment.

[0175] FIG. 9 shows the amount of charge charged between the first terminal and the second terminal of a piezo actuator and the voltage output through a comparison circuit according to one embodiment.

[0176] Referring to FIG. 8, the piezo actuator (370) can be connected to the processor (380). For example, to output vibration through the piezo actuator (370), the processor (380) can be connected to the piezo actuator (370) through the piezo actuator management circuit (375). The processor (380) can be connected to the piezo actuator management circuit (375) through the path (830). The piezo actuator management circuit (375) can be connected to the piezo actuator (370).

[0177] For example, the piezo actuator (370) may be connected to the processor (380) via a DC block (811, 812) and a comparison circuit (820) to provide (or transmit, output) a second signal to the processor (380) indicating that pressure on the button (310) and / or button (320) is identified.

[0178] According to one embodiment, the piezo actuator (370) may include a first terminal (801) and a second terminal (802). For example, the first terminal (801) may be connected to a DC block (811). The first terminal (801) may be connected to a piezo actuator management circuit (375). For example, the second terminal (802) may be connected to a DC block (812). The second terminal (802) may be connected to a piezo actuator management circuit (375). According to an embodiment, the piezo actuator (370) may be connected to the DC block (811) and the piezo actuator management circuit (375) through different terminals. According to an embodiment, the piezo actuator (370) can be connected to the DC block (812) and the piezo actuator management circuit (375) through different terminals.

[0179] According to one embodiment, the processor (380) can apply a voltage for outputting vibration to the piezo actuator (370) through the first terminal (801) and the second terminal (802). Based on the applied voltage, the piezo actuator (370) can output vibration.

[0180] According to one embodiment, the voltage difference between the first terminal (801) and the second terminal (802) may be changed based on pressure on the button (310) and / or the button (320). For example, since the piezo actuator (370) is a piezoelectric element, the voltage difference between the first terminal (801) and the second terminal (802) may be changed based on pressure on the button (310) and / or the button (320).

[0181] For example, the DC block (811) can provide the DC (direct current) voltage of the first terminal (801) to the comparison circuit (820). The DC block (812) can provide the DC voltage of the second terminal (802) to the comparison circuit (820). The comparison circuit (820) can identify the voltage difference between the DC voltage of the first terminal (801) and the DC voltage of the second terminal (802). For example, the comparison circuit (820) can be configured to output a second signal based on the voltage difference between the first terminal (801) and the second terminal (802). For example, if the voltage difference between the first terminal (801) and the second terminal (802) is within a reference voltage range, the comparison circuit (820) can output a second signal. If the voltage difference between the first terminal (801) and the second terminal (802) is outside the reference voltage, the comparison circuit (820) may refrain from outputting the second signal.

[0182] For example, based on pressure on the button (310) and / or the button (320), the voltage difference between the first terminal (801) and the second terminal (802) may be changed to within a reference voltage range. Accordingly, the comparison circuit (820) may output a second signal based on pressure on the button (310) and / or the button (320). The second signal may be provided to the processor (380).

[0183] According to one embodiment, since the piezo actuator (370) is connected to the processor (380) through the comparison circuit (820), the piezo actuator (370) can provide a second signal to the processor (380) regardless of whether the piezo actuator management circuit (375) is operating. According to one embodiment, the magnitude of the voltage applied to the piezo actuator (370) may be greater than the voltage difference that changes based on the pressure on the button (310) and / or button (320). Thus, the comparison circuit (820) can identify whether the voltage difference that changes based on the pressure on the button (310) and / or button (320) is within a reference voltage range while the voltage for outputting vibration is applied to the first terminal (801) and the second terminal (802).

[0184] Referring to FIG. 9, the graph (901) represents the amount of charge charged between the first terminal (801) and the second terminal (802) over time. The graph (901) may also represent the voltage difference between the first terminal (801) and the second terminal (802). The graph (902) represents the magnitude of the voltage output through the comparison circuit (820) over time. For example, at time point (910) and time point (920), pressure may be applied to the button (310).

[0185] Based on the pressure applied to the button (310) at time point (910, 920), the amount of charged electric charge between the first terminal (801) and the second terminal (802) of the piezo actuator (370) may be changed. The comparison circuit (820) may output a second signal at time point (910, 920) based on identifying that the voltage difference between the first terminal (801) and the second terminal (802) is within a reference voltage range.

[0186] According to one embodiment, the processor (380) can identify that pressure is applied to the button (310) (or button (320)) based on identifying that the second signal is maintained for a reference time.

[0187] FIG. 10a illustrates a flowchart regarding the operation of an electronic device according to one embodiment. In the following examples, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0188] Referring to FIG. 10a, the electronic device (300) may include a housing (301). The electronic device (300) may include a first button (e.g., button (310)), a second button (e.g., button (320)), and a third button (e.g., button (330)) disposed on the side of the housing (301). The electronic device (300) may include a first pressure sensor (e.g., pressure sensor (361)) for sensing a first pressure on the first button. The electronic device (300) may include a second pressure sensor (e.g., pressure sensor (362)) for sensing a second pressure on the second button. The electronic device (300) may include a switch circuit (e.g., switch (363)) for sensing an input on the third button.

[0189] In operation 1001, the processor (380) of the electronic device (300) can identify a first pressure on a first button (e.g., button (310)). The processor (380) can identify the first pressure by using a first pressure sensor (e.g., pressure sensor (361)) for sensing (or identifying) the first pressure on the first button. The first pressure sensor may be placed under the first button.

[0190] In operation 1002, the processor (380) may output a first vibration corresponding to a first pressure. For example, the processor (380) may output a first vibration corresponding to a first pressure through a vibration element based on identifying the first pressure. The vibration element may include a piezo actuator. However, the present disclosure is not limited thereto. For example, the processor (380) may provide vibration toward a first button through a vibration element. The processor (380) may provide vibration toward a first button so that the user recognizes that an input to the first button has been performed.

[0191] In operation 1003, the processor (380) can identify a second pressure on a second button (e.g., button (320)). The processor (380) can identify the second pressure by using a second pressure sensor (e.g., pressure sensor (362)) to sense (or identify) the second pressure on the second button. The second pressure sensor may be placed under the second button.

[0192] In operation 1004, the processor (380) may output a second vibration corresponding to a second pressure. For example, the processor (380) may output a second vibration corresponding to a second pressure through a vibration element based on identifying the second pressure. The vibration element may include a piezo actuator, but is not limited thereto. For example, the processor (380) may provide vibration toward a second button through a vibration element. The processor (380) may provide vibration toward a second button so that the user recognizes that an input to the second button has been performed.

[0193] According to one embodiment, the vibration element may be configured to identify at least one of a first pressure and a second pressure. For example, the vibration element may include a first terminal and a second terminal. Depending on the pressure on the first button (or the second button), the voltage difference between the first terminal and the second terminal may change. The processor (380) may identify a third pressure on the first button (or the second button) based on the voltage difference between the first terminal and the second terminal.

[0194] According to one embodiment, the processor (380) can identify a third pressure for the first button through a vibration element while the first pressure for the first button is not identified using a first pressure sensor. For example, the first pressure may be the pressure for the first button identified using the first pressure sensor. The third pressure may be the pressure for the first button identified using a vibration element.

[0195] The processor (380) may not be able to identify a first pressure on the first button using a first pressure sensor. The processor (380) may identify a third pressure on the first button using a vibration element. The processor (380) may not be able to identify a pressure on the first button (e.g., first pressure) through the pressure sensor, but may identify a pressure on the first button (e.g., third pressure) through the vibration element. Therefore, if the first pressure on the first button is not identified using the first pressure sensor, and the third pressure on the first button is identified through the vibration element, the processor (380) may identify a malfunction of the first button.

[0196] According to one embodiment, the processor (380) can identify a fourth pressure for the second button through a vibration element while the second pressure for the second button is not identified using a second pressure sensor. For example, the second pressure may be the pressure for the second button identified using the second pressure sensor. The fourth pressure may be the pressure for the second button identified using a vibration element.

[0197] The processor (380) may not be able to identify a second pressure on the second button using a second pressure sensor. The processor (380) may identify a fourth pressure on the second button using a vibration element. The processor (380) may not be able to identify a pressure on the second button (e.g., second pressure) through the pressure sensor, but may identify a pressure on the second button (e.g., fourth pressure) through the vibration element. Therefore, if the second pressure on the second button is not identified using the second pressure sensor, and the fourth pressure on the second button is identified through the vibration element, the processor (380) may identify a malfunction of the second button.

[0198] According to one embodiment, the processor (380) may display a user interface indicating the identified malfunction through a display of an electronic device based on identifying a malfunction of at least one of the first button and / or the second button.

[0199] According to one embodiment, while identifying a malfunction of the first button, the processor (380) may identify a third pressure on the first button using a vibration element and identify an input on the third button using a switch circuit. The processor (380) may identify that the third pressure and the input on the third button are maintained for a reference time. In response to identifying that the third pressure and the input on the third button are maintained for a reference time, the processor (380) may reset the electronic device (300).

[0200] FIG. 10b illustrates a flowchart regarding the operation of an electronic device according to one embodiment. In the following examples, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0201] Referring to FIG. 10b, the electronic device (300) may include a housing (301). The electronic device (300) may include a first button (e.g., button (310)), a second button (e.g., button (320)), and a third button (e.g., button (330)) disposed on the side of the housing (301). The electronic device (300) may include a first pressure sensor (e.g., pressure sensor (361)) for sensing a first pressure on the first button. The electronic device (300) may include a second pressure sensor (e.g., pressure sensor (362)) for sensing a second pressure on the second button. The electronic device (300) may include a switch circuit (e.g., switch (363)) for sensing an input on the third button.

[0202] In operation 1010, the processor (380) of the electronic device (300) can detect a malfunction related to the first button (e.g., button (310)) based on receiving a second signal from the piezo actuator (370) while the first signal from the first pressure sensor (e.g., pressure sensor (361)) is not provided to the processor (380).

[0203] According to one embodiment, a pressure sensor may provide (or transmit, output) a first signal to a processor (380) based on a first pressure on a first button (e.g., button (310)). The processor (380) may identify that a first pressure has been applied to the first button based on the first signal. A piezo actuator (370) may provide (or transmit, output) a second signal to the processor (380) based on a first pressure on the first button (e.g., button (310)).

[0204] According to one embodiment, the piezo actuator (370) may include a first terminal (e.g., the first terminal (801) of FIG. 8) and a second terminal (e.g., the second terminal (802) of FIG. 8). The electronic device (300) may include a comparison circuit (e.g., the comparison circuit (820) of FIG. 8) configured to output a second signal based on the voltage difference between the first terminal and the second terminal. The piezo actuator (370) may be connected to a processor (380) through the comparison circuit (820). For example, the comparison circuit may be configured to output a second signal when the voltage difference between the first terminal and the second terminal is within a reference voltage range. The comparison circuit may be configured to refrain from outputting the second signal when the voltage difference between the first terminal and the second terminal is outside the reference voltage.

[0205] According to one embodiment, the processor (380) may receive a second signal from the piezo actuator (370) while the first signal is not provided to the processor (380). Since both the first signal and the second signal are provided by pressure from the first button, the processor (380) may detect a malfunction related to the first button based on receiving the second signal from the piezo actuator (370) while the first signal is not provided to the processor (380).

[0206] According to an embodiment, the processor (380) may output vibration through the piezo actuator (370) based on pressure on the first button. The processor (380) may apply a voltage for outputting vibration to the piezo actuator (370) through the first terminal and the second terminal. According to an embodiment, the processor (380) may refrain from applying a voltage for outputting vibration through the first terminal and the second terminal while the first signal is not provided to the processor (380).

[0207] In operation 1020, the processor (380) can identify that the second signal and the third signal indicating pressure on the third button are maintained for a reference time. The processor (380) can identify the third signal based on the pressure on the third button (e.g., button (330)). The processor (380) can identify that the second signal and the third signal are maintained for a reference time.

[0208] For example, the processor (380) may execute the function assigned to the first pressure on the first button and the input on the third button based on identifying that the first pressure on the first button and the input on the third button are maintained for a reference time. As an example, the processor (380) may perform a reset of the electronic device (300) based on identifying that the pressure on the first button and the input on the third button are maintained for a reference time. The processor (380) may perform a reset of the electronic device (300) based on pressing the first button and the third button together for a specified time.

[0209] For example, based on the first signal being provided to the processor (380), the processor (380) may execute the function in response to the first signal and the third signal being maintained for a reference time.

[0210] For example, depending on the malfunction of the first button, a first signal indicating pressure for the first button may not be provided from the pressure sensor. As in operation 1010, the processor (380) can detect the malfunction associated with the first button based on receiving a second signal while the first signal is not provided. The processor (380) can detect the malfunction of the first button and identify whether the second signal is maintained for a reference time.

[0211] In operation 1030, the processor (380) can execute a function assigned to a combination of pressure on the first button and input on the third button. For example, the processor (380) can execute a function assigned to a combination of pressure on the first button and input on the third button in response to the second signal and the third signal being maintained for a reference time. For example, a function assigned to a combination of pressure on the first button and input on the third button may be related to a reset of the electronic device (300). The processor (380) can provide a control signal to the power management circuit (395) to execute a function assigned to a combination of pressure on the first button and input on the third button. The processor (380) can perform a reset of the electronic device (300) using the power management circuit (395).

[0212] FIG. 11 illustrates an example of a processor configuration according to one embodiment.

[0213] FIG. 12 illustrates a flowchart regarding the operation of an auxiliary processor included in a processor according to one embodiment. In the following examples, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0214] Referring to FIG. 11, a processor (380) (e.g., a processor including a processing circuit) may include a main processor (381) (e.g., a main processor including a processing circuit) and an auxiliary processor (382) (e.g., an auxiliary processor including a processing circuit). For example, when the main processor (381) is operating normally, the main processor (381) may identify pressure on the button (310) based on identifying a first signal provided from the pressure sensor (361). Based on the pressure on the button (310), the main processor (381) may output vibration through a piezo actuator (370). The output vibration may be transmitted to the button (310). Based on the vibration transmitted to the button (310), the processor (380) may provide a haptic effect.

[0215] According to one embodiment, the main processor (381) may be configured for an operating system (OS). An auxiliary processor (382) may be configured to compensate for a malfunction of the main processor (381). According to an embodiment, the auxiliary processor (382) may be configured for the management of at least one pressure sensor (e.g., pressure sensor (361), pressure sensor (362)), a switch (363), and / or a piezo actuator (370). The auxiliary processor (382) may be referred to as a sensor hub.

[0216] Although not illustrated, for example, the main processor (381) may perform operations based on one or more instructions (or commands) representing operations to be performed and / or operations. According to an embodiment, the one or more instructions may be stored in memory (390) of the electronic device (300). For example, the main processor (381) may include an application layer, a framework layer, a hardware abstraction layer, and / or a Linux kernel. For example, the auxiliary processor (382) may include a layer for managing at least one pressure sensor (e.g., pressure sensor (361), switch (363), pressure sensor (362)) and / or a piezo actuator (370) and a layer for a neural processing unit (NPU).

[0217] According to one embodiment, the piezo actuator (370) may provide a second signal to the processor (380) based on pressure on the button (310). The main processor (381) may identify the second signal. The main processor (381) may identify a malfunction of the button (310) based on identifying the second signal while the first signal is not received. Based on the malfunction of the button (310), the main processor (381) may identify that a third signal indicating the second signal and input to the button (330) is maintained for a reference time. In response to identifying that the second signal and the third signal are maintained for a reference time, the main processor (381) may execute a function assigned to the combination of pressure on the button (310) and input to the button (330). For example, the function assigned to the combination of pressure on the button (310) and input on the button (330) may be related to the reset of the electronic device (300). The main processor (381) may provide (or transmit) a control signal to the power management circuit (395) to perform the function assigned to the combination of pressure on the button (310) and input on the button (330).

[0218] According to one embodiment, if a malfunction occurs in the main processor (381), the auxiliary processor (382) can perform functions related to at least one pressure sensor and a piezo actuator (370). If a malfunction occurs in the main processor (381), the operation of the auxiliary processor (382) may correspond to operations 1201 to 1204 of FIG. 12.

[0219] Referring to FIG. 12, in operation 1201, the auxiliary processor (382) can identify whether a state abnormality of the main processor (381) has been identified. For example, if a state abnormality of the main processor (381) occurs, the auxiliary processor (382) operates in a preliminary manner, so the auxiliary processor (382) can identify whether a state abnormality of the main processor (381) has been identified. If no state abnormality of the main processor (381) is identified, the main processor (381) operates normally, so the auxiliary processor (382) can perform operation 1201 according to a specified time interval.

[0220] In operation 1202, the auxiliary processor (382) can identify whether a malfunction of the first button (e.g., button (310)) has been identified. For example, if inputs to the first button and the third button are maintained for a reference time, the processor (380) may be configured to perform a reset of the electronic device (300). If a state abnormality occurs in the main processor (381), the reset of the electronic device (300) may not be performed. Therefore, the auxiliary processor (382) can identify a malfunction of the first button in order to perform a reset of the electronic device (300). For example, the auxiliary processor (382) can identify a malfunction of the first button based on identifying a second signal provided from the piezo actuator (370) while a first signal is not provided from the pressure sensor (e.g., pressure sensor (361)) corresponding to the first button.

[0221] According to one embodiment, if a malfunction of the first button is not identified, the auxiliary processor (382) may perform operation 1201. If a malfunction of the first button is not identified, the auxiliary processor (382) may perform operation 1201 according to a specified time interval.

[0222] In operation 1203, if a malfunction of the first button is identified, the auxiliary processor (382) can identify whether the second signal and the third signal are maintained for a reference time. For example, the auxiliary processor (382) can identify that the second signal is provided from the piezo actuator (370) and identify the third signal provided according to the input of the third button. The auxiliary processor (382) can identify whether the second signal and the third signal are maintained for a reference time.

[0223] According to one embodiment, if the second signal and the third signal are not maintained for a reference time, the auxiliary processor (382) may perform operation 1203 again according to a specified time interval.

[0224] In operation 1204, if the second signal and the third signal are maintained for a reference time, the auxiliary processor (382) can execute the function assigned to the combination of pressure on the first button and input on the third button. For example, the auxiliary processor (382) can transmit a control signal to the power management circuit (395) to control the power management circuit (395) in order to execute the function assigned to the combination of pressure on the first button and input on the third button (e.g., reset of the electronic device (300)).

[0225] According to an embodiment, the power management circuit (395) may perform a function assigned to a combination of pressure on the first button and input on the third button (e.g., reset of the electronic device (300)) depending on whether the first signal and the third signal have been maintained for a reference time. The auxiliary processor (382) may generate a first signal based on identifying a second signal provided from the piezo actuator (370) and provide the generated first signal to the power management circuit (395). The power management circuit (395) may identify whether the first signal and the third signal have been maintained for a reference time and perform a function assigned to a combination of pressure on the first button and input on the third button (e.g., reset of the electronic device (300)).

[0226] FIG. 13 illustrates an example of the structure of a button assembly according to one embodiment.

[0227] FIG. 14 illustrates an example of an operation in which signals are provided from piezo actuators to a processor according to one embodiment.

For example, the base frame (313) may correspond to the base frame (313) of FIG. 4b. The printed circuit board (1380) may correspond to the printed circuit board (423) of FIG. 4b.

[0230] According to one embodiment, the pressure sensor (361) and the pressure sensor (362) may be placed below the printed circuit board (1380).

[0232] For example, the first waterproof member (1361) may be attached to a part of the base frame (313). The first waterproof member (1361) may be positioned between the part of the base frame (313) and the piezo actuator (371). The first waterproof member (1361) can prevent / block foreign substances, such as dust and / or moisture, from entering the piezo actuator (371).

[0233] For example, the second waterproof member (1362) may be attached to another part of the base frame (313). The second waterproof member (1362) may be positioned between the other part of the base frame (313) and the piezo actuator (372).

[0235] According to one embodiment, pressure on another area of ​​the base frame (313) corresponding to the pressure sensor (362) (e.g., area (343) of FIG. 3a) can be transmitted to the piezo actuator (372) and / or the pressure sensor (362) through the second waterproof member (1362).

[0236] According to one embodiment, a piezo actuator (371) may be positioned between a pressure sensor (361) and a base frame (313). The piezo actuator (371) may be configured to output vibration (or haptic feedback) based on pressure on a region of the base frame (313) (e.g., region (341) in FIG. 3a). Pressure on a region of the base frame (313) (e.g., region (341) in FIG. 3a) may be generated by user input. User input on a region of the base frame (313) (e.g., region (341) in FIG. 3a) may include gesture input and / or press input. For example, depending on user input on a region of the base frame (313) (e.g., region (341) in FIG. 3a), the vibration pattern output through the piezo actuator (371) may be changed.

[0237] According to one embodiment, a piezo actuator (372) may be positioned between a pressure sensor (362) and a base frame (313). The piezo actuator (372) may be configured to output vibration (or haptic feedback) based on pressure on another area of ​​the base frame (313) (e.g., area (343) in FIG. 3a). Pressure on another area of ​​the base frame (313) (e.g., area (343) in FIG. 3a) may be generated by user input. User input on another area of ​​the base frame (313) (e.g., area (343) in FIG. 3a) may include gesture input and / or press input. For example, depending on user input on another area of ​​the base frame (313) (e.g., area (343) in FIG. 3a), the vibration pattern output through the piezo actuator (372) may be changed.

[0238] According to one embodiment, the first elastic member (1368) may be positioned so that, depending on the pressure applied to one area (e.g., area (341)) of the base frame (313), a portion of the base frame (313) corresponding to one area of ​​the base frame (313) is drawn into the housing (301).

The piezo actuator management circuit (375) may be connected to the piezo actuator (371) and / or the piezo actuator (372).

[0240] According to one embodiment, the piezo actuator (371) may be connected to the processor (380) through a DC block (1411, 1412) and a comparison circuit (821) to provide (or transmit, output) a signal to the processor (380) indicating that pressure on the button (310) is identified.

[0241] According to one embodiment, the piezo actuator (372) may be connected to the processor (380) through a DC block (1421, 1422) and a comparison circuit (822) to provide (or transmit, output) a signal to the processor (380) indicating that pressure on the button (320) is identified.

[0244] According to one embodiment, the processor (380) can apply a voltage for outputting vibration to the piezo actuator (371) through the first terminal (1401) and the second terminal (1402). Based on the applied voltage, the piezo actuator (371) can output vibration.

[0245] According to one embodiment, the processor (380) can apply a voltage for outputting vibration to the piezo actuator (372) through the third terminal (1403) and the fourth terminal (1404). Based on the applied voltage, the piezo actuator (372) can output vibration.

[0246] According to one embodiment, the voltage difference between the first terminal (1401) and the second terminal (1402) may be changed based on pressure on the button (310). For example, since the piezo actuator (371) is a piezoelectric element, the voltage difference between the first terminal (1401) and the second terminal (1402) may be changed based on pressure on the button (310) and / or the button (330).

[0247] For example, the DC block (1411) can provide the DC (direct current) voltage of the first terminal (1401) to the comparison circuit (821). The DC block (1412) can provide the DC voltage of the second terminal (1402) to the comparison circuit (821). The comparison circuit (821) can identify the voltage difference between the DC voltage of the first terminal (1401) and the DC voltage of the second terminal (1402). For example, the comparison circuit (821) can be configured to output a signal based on the voltage difference between the first terminal (1401) and the second terminal (1402). For example, if the voltage difference between the first terminal (1401) and the second terminal (1402) is within a reference voltage range, the comparison circuit (821) can output a signal. If the voltage difference between the first terminal (1401) and the second terminal (1402) is outside the reference voltage, the comparison circuit (821) may refrain from outputting a signal.

[0248] For example, based on pressure on the button (310), the voltage difference between the first terminal (1401) and the second terminal (1402) may be changed to within a reference voltage range. Accordingly, the comparison circuit (821) may output a signal based on pressure on the button (310). The signal may be provided to the processor (380). The signal may indicate that pressure has been applied to the button (310).

[0249] According to one embodiment, the voltage difference between the third terminal (1403) and the fourth terminal (1404) can be changed based on the pressure on the button (320). For example, since the piezo actuator (371) is a piezoelectric element, the voltage difference between the third terminal (1403) and the fourth terminal (1404) can be changed based on the pressure on the button (320).

[0250] For example, the DC block (1411) can provide the DC (direct current) voltage of the third terminal (1403) to the comparison circuit (822). The DC block (1412) can provide the DC voltage of the fourth terminal (1404) to the comparison circuit (822). The comparison circuit (822) can identify the voltage difference between the DC voltage of the third terminal (1403) and the DC voltage of the fourth terminal (1404). For example, the comparison circuit (822) can be configured to output a signal based on the voltage difference between the third terminal (1403) and the fourth terminal (1404). For example, if the voltage difference between the third terminal (1403) and the fourth terminal (1404) is within a reference voltage range, the comparison circuit (822) can output a signal. If the voltage difference between the third terminal (1403) and the fourth terminal (1404) is outside the reference voltage, the comparison circuit (822) may refrain from outputting a signal.

[0251] For example, based on pressure on the button (320), the voltage difference between the third terminal (1403) and the fourth terminal (1404) can be changed to within a reference voltage range. Accordingly, the comparison circuit (822) can output a signal based on pressure on the button (320). The signal can be provided to the processor (380). The signal can indicate that pressure has been applied to the button (320).

[0263] For example, the first pressure sensor may be placed below the first button. The second pressure sensor may be placed below the second button.

[0264] According to one embodiment, a method performed by an electronic device may include: identifying whether a first signal from a first pressure sensor is provided to at least one processor of the electronic device according to a first pressure on the first button among the first button, the second button, and the third button of the electronic device according to a first pressure; identifying an input to the first button based on whether the first signal from the first pressure sensor is provided to the at least one processor according to the first pressure; detecting a malfunction associated with the first button based on receiving a second signal from a vibration element of the electronic device while the first signal from the first pressure sensor is not provided to the at least one processor; and executing a function assigned to a combination of the pressure on the first button and the input to the third button in response to the second signal and a third signal indicating an input to the third button being maintained for a reference time based on the malfunction associated with the first button.

[0265] For example, the electronic device may include a vibration element. The vibration element may include a first terminal and a second terminal.

[0266] For example, the voltage difference between the first terminal and the second terminal may be changed based on the pressure applied to the first button. The electronic device is configured to output the second signal based on the voltage difference between the first terminal and the second terminal of the vibration element and may include a comparison circuit for connecting the vibration element and the at least one processor.

[0267] For example, the comparison circuit may be configured to output the second signal when the voltage difference between the first terminal and the second terminal is within a reference voltage range, and to refrain from outputting the second signal when the voltage difference between the first terminal and the second terminal is outside the reference voltage range.

[0268] For example, the above method may include the operation of applying a voltage to the vibration element to output the vibration through the first terminal and the second terminal based on the identification of the first signal, and the operation of refraining from applying the voltage to the vibration element to output the vibration through the first terminal and the second terminal while the first signal from the first pressure sensor is not provided to the at least one processor.

[0281] For example, the electronic device may further include a third button disposed on the side of the housing, and a switch circuit for sensing an input to the third button. When the instructions are executed individually or collectively by the at least one processor, they may cause the electronic device to reset in response to the first pressure on the first button and the input to the third button being maintained for a reference time.

[0293] According to the above-described embodiment, a first button of the electronic device (e.g., button (310)) may be configured as a digital button including a pressure sensor (e.g., pressure sensor (361)). If the first button is configured as a digital button, an input to the first button may not be identified when a functional failure of the first button occurs. When pressure (or input) is applied to the first button and the third button (e.g., button (330)) for a reference time, a reset of the electronic device (300) may be performed. Since pressure to the first button cannot be identified when a functional failure of the first button occurs, the electronic device (300) may use a piezo actuator to identify whether pressure is applied to the first button. The electronic device may identify that pressure has been applied to the first button through a second signal provided through the piezo actuator. Accordingly, the electronic device can perform a reset of the electronic device based on identifying that pressure on the first button and input on the third button are maintained for a reference time.

[0294] The electronic device can identify the pressure on the first button through a piezo actuator and a pressure sensor. The piezo actuator can perform an auxiliary function of the pressure sensor. Additionally, since the electronic device can identify the pressure on the first button through the piezo actuator and the pressure sensor, the accuracy of the input can be increased.
