[0101] In one embodiment, the plurality of coils (440) may be referred to as “coils.” The coils (440) may be spaced apart from the magnets (430). A current may be applied to the coils (440). An electromagnetic force may be formed between the coils (440) and the magnets (430). The gap (G) between the coils (440) and the magnets (430) may change when the magnets (430) are moved. For example, when the button (410) is pressed, the magnets (430) may move toward the coils (440), and the gap (G) between the magnets (430) and the coils (440) may become smaller.

[0102] In one embodiment, a plurality of sensors (450) may be referred to as “sensors.” The sensor (450) may face the magnet (430).

[0104] According to one embodiment, the sensor (450) can detect the pressing of the button (410) based on the strength of the induced current (C1) flowing in the coil (440) due to the movement of the magnet (430). For example, an electromagnetic force may be formed between the magnet (430) and the coil (440). The electromagnetic force may be formed according to Faraday's law of electromagnetic induction. Due to a change in the gap (G) between the magnet (430) and the coil (440), an induced current (C1) may flow in the circuit (470). For example, as illustrated in FIG. 7b, when the magnet (430) moves in the first direction (D1) toward the coil (440), an induced current (C1) may flow in the circuit (470). For example, as illustrated in FIG. 7b, the magnet (430) can form a magnetic field in a first magnetic field direction (M1), and the coil (440) can form a magnetic field in a second magnetic field direction (M2) opposite to the first magnetic field direction (M1) by an induced current (C1). Referring to FIG. 7b, a repulsive force can be formed between the magnet (430) and the coil (440). The sensor (450) can detect the electromagnetic force formed between the magnet (430) and the coil (440). The sensor (450) can detect the magnitude of the induced current (C1) flowing in the circuit (470). For example, the circuit (470) can include a galvanometer (471) disposed between a first position (472) and a second position (473). The galvanometer (471) can be configured to detect the direction (D2) and intensity of the induced current (C1) flowing in the circuit (470). For example, the sensor (450) can be connected to the galvanometer (471) and receive information about the induced current (C1) detected by the galvanometer (471).For example, the sensor (450) can transmit information about the induced current (C1) received from the galvanometer (471) to the signal processing device (e.g., the signal processing device (481) of FIGS. 10A and 10B) of the driving chip (e.g., the driving chip (480) of FIGS. 10A and 10B), and the driving chip (480) can detect the pressing of the button (410) based on the information. The sensor (450) can detect the gap (G) between the magnet (430) and the coil (440). The sensor (450) can detect the size of the second magnetic field formed by the coil (440). However, an operation of detecting the pressing of the button (410) based on the intensity of the induced current (C1) flowing in the coil (440) by the movement of the magnet (430), as described with reference to FIG. 7b, may be an embodiment of the present disclosure. For example, a button assembly (400) according to an embodiment of the present disclosure may detect the pressing of the button (410) based on a change in magnetic flux between the magnet (430) and the sensor (450), as described with reference to FIG. 7a.

[0105] FIG. 8 is a graph exemplarily explaining a change in voltage applied to a coil (440) and the movement of a button (410) based on acceleration. FIG. 9a is an example of a change in voltage applied to a coil (440) and the acceleration at which the button (410) operates accordingly. FIG. 9b is an example of a change in voltage applied to a coil (440) and the acceleration at which the button (410) operates accordingly. FIG. 9c is an example of a change in voltage applied to a coil (440) and the acceleration at which the button (410) operates accordingly. FIG. 9d is an example of a change in voltage applied to a coil (440) and the acceleration at which the button (410) operates accordingly. The components described with reference to FIGS. 8 to 9d may be some or all the same as the components described with reference to FIGS. 1 to 7b. The components described with reference to FIGS. 8 to 9d may be partially or entirely the same as the components described with reference to FIGS. 10a to 14.

[0106] According to one embodiment, the movement of the button (410) may be determined based on the voltage applied to the coil (440). For example, referring to FIG. 8, the button (410) may move with the maximum acceleration (A1) after the voltage intensity (V1) applied to the coil (440) becomes maximum. The electronic device (101) according to an embodiment of the present disclosure may control the feedback signal (output signal) transmitted through the button (410) by controlling the voltage intensity applied to the coil (440), the shape of the voltage wave, or the time for which the voltage is applied. For example, as shown in FIG. 8, when voltage is applied to the coil (440), the button (410) may move with an acceleration having a large amplitude (A1) instantaneously, thereby providing the user with an instantaneous vibration sensation.

[0107] In the description with reference to FIGS. 9A to 9D, the X-axis may represent the flow of time. The Y-axis may represent the voltage applied to the coil (440) and the acceleration at which the button (410) operates. The graphs described with reference to FIGS. 9A to 9D may represent the change in voltage that changes over time and the change in acceleration at which the button (410) operates according to the change in voltage.

[0108] Referring to Fig. 9a, when a voltage such as a first voltage waveform (V11) is applied to the coil (440), the button (410) can move according to a first acceleration waveform (A11). When a voltage is applied in a form such as Fig. 9a, the button assembly (400) can provide a click sensation to the user. A voltage waveform in a form such as Fig. 9a can be named a "click waveform."

[0109] Referring to Fig. 9b, when a voltage such as a second voltage waveform (V12) is applied to the coil (440), the button (410) can move according to a second acceleration waveform (A12). When a voltage is applied in a form such as Fig. 9b, the button assembly (400) can provide the user with a clicking sensation for a longer period of time compared to Fig. 9a. A voltage waveform in a form such as Fig. 9b can be called a "ramp waveform."

[0110] Referring to Fig. 9c, when a voltage such as a third voltage waveform (V13) is applied to the coil (440), the button (410) can move according to a third acceleration waveform (A13). When a voltage is applied in a form such as Fig. 9c, the button assembly (400) can provide a vibration (buzz) to the user. A voltage waveform in a form such as Fig. 9c can be named a "buzz waveform."

[0111] Referring to Fig. 9d, when a voltage such as the fourth voltage waveform (V14) is applied to the coil (440), the button (410) can move according to the fourth acceleration waveform (A14). When a voltage is applied in a form such as Fig. 9d, the button assembly (400) can provide a pulse to the user. A voltage waveform in a form such as Fig. 9d can be called a "pulse waveform."

[0112] Fig. 10a is a diagram explaining how an input signal is transmitted to a driving circuit (480). Fig. 10b is a diagram explaining how an output signal is transmitted from the driving circuit (480). The components described with reference to Figs. 10a and 10b may be partly or entirely the same as the components described with reference to Figs. 1 to 9d. The components described with reference to Figs. 10a and 10b may be partly or entirely the same as the components described with reference to Figs. 11 to 14.

[0113] According to one embodiment, the button assembly (400) may include a driving circuitry (480). The driving circuitry (480) may be referred to as “circuitry.” The driving circuitry (480) may be disposed on a button assembly substrate (e.g., the button assembly substrate (460) of FIG. 6). The driving circuitry (480) may be connected to a printed circuit board (e.g., the printed circuit board (340a) of FIGS. 4 and 5) via the button assembly substrate (460).

[0114] According to one embodiment, the driving circuit (480) may include a signal processing part (481). The driving circuit (480) may include an input part (482). The driving circuit (480) may include an output part (483). The driving circuit (480) may include a filter (484). The signal processing part (481) may be connected to the input part (482), the output part (483), and the filter (484). The input part (482) may be connected to a plurality of sensors (450). The input part (482) may receive first signals (IS1, IS2, IS3, IS4, ISn) from the plurality of sensors (450). The output part (483) may transmit second signals (OS1, OS2, OS3, OS4, OSn) to the plurality of coils (440). The filter (484) can remove noise included in the first signals (IS1, IS2, IS3, IS4, ISn) transmitted from the plurality of sensors (450). For example, the button (410) can operate (e.g., the operations described with reference to FIGS. 9A to 9D) by the second signals (OS1, OS2, OS3, OS4, OSn) transmitted to the plurality of coils (440), and noise may be included in the signals detected by the plurality of sensors (450) by the operation of the button (410). The filter (484) can remove noise included in the signals detected by the plurality of sensors (450) by the operation of the button (410). The signal processing part (481) can generate the second signals (OS1, OS2, OS3, OS4, OSn) based on the first signals (IS1, IS2, IS3, IS4, ISn) from which noise has been removed through the filter (484). For example, the filter (484) can remove noise by using an algorithm that removes signals transmitted at a predetermined time interval from the time at which the first signals (IS1, IS2, IS3, IS4, ISn) are transmitted from the plurality of sensors (450).The signal processing part (481) can receive a first signal (IS1, IS2, IS3, IS4, ISn) through the input part (482) and transmit a second signal (OS1, OS2, OS3, OS4, OSn) through the output part (483).

[0115] According to one embodiment, the driving circuit (480) can receive first signals (IS1, IS2, IS3, IS4, ISn) from a plurality of sensors (451, 452, 453, 454, 450n). The driving circuit (480) can be connected to a plurality of sensors (450) and can receive first signals (IS1, IS2, IS3, IS4, ISn) from the plurality of sensors (450). The first signals (IS1, IS2, IS3, IS4, ISn) can be generated by the method described with reference to FIGS. 7A and 7B. For example, the first signals (IS1, IS2, IS3, IS4, ISn) can include information about changes in electromagnetic force based on movement of the magnet (430). A plurality of sensors (450) can detect information about the electromagnetic force formed by the movement of the magnet (430) (e.g., change in magnetic flux formed by the magnet (430), size of induced current, strength of magnetic field, gap between the magnet and the sensor) and transmit the information to the driving circuit (480). The first signals (IS1, IS2, IS3, IS4, ISn) may be named “input signals.” The first signals (IS1, IS2, IS3, IS4, ISn) may be named “detection signals.”

[0116] According to one embodiment, the first signals (IS1, IS2, IS3, IS4, ISn) detected by each of the plurality of sensors (450) may be transmitted to the driving circuit (480) at different times. For example, the time at which the 1-1 signal (IS1) detected by the first sensor (451) is transmitted to the driving circuit (480) and the time at which the 1-2 signal (IS2) detected by the second sensor (452) is transmitted to the driving circuit (480) may be different. For example, referring to FIG. 10A, when the button (410) is pressed along the sliding direction (S1), the 1-1 signal (IS1) may be transmitted to the driving circuit (480) before the 1-2 signal (IS2). For example, referring to FIG. 10A, when the button (410) is pressed along the sliding direction (S1), the first-first signal (IS1) detected by the first sensor (451), the first-second signal (IS2) detected by the second sensor (452), the first-third signal (IS3) detected by the third sensor (453), and the first-fourth signal (IS4) detected by the fourth sensor (454) may be sequentially transmitted to the driving circuit (480). The driving circuit (480) may confirm the order in which the first signals (IS1, IS2, IS3, IS4, ISn) are transmitted from each of the plurality of sensors (450). The driving circuit (480) can transmit the second signal (OS1, OS2, OS3, OS4, OSn) to the button assembly (400) or the display (e.g., the display (220) of FIGS. 2 and 3) based on the order in which the first signals (IS1, IS2, IS3, IS4, ISn) are transmitted from each of the plurality of sensors (450). The driving circuit (480) can display a screen corresponding to the order in which the first signals (IS1, IS2, IS3, IS4, ISn) are transmitted on the display (220) based on the order in which the first signals (IS1, IS2, IS3, IS4, ISn) are transmitted from each of the plurality of sensors (450).A memory (e.g., memory (130) of FIG. 1) can store instructions regarding a screen corresponding to the order in which the first signals (IS1, IS2, IS3, IS4, ISn) are transmitted.

[0117] According to one embodiment, the driving circuit (480) can transmit the second signals (OS1, OS2, OS3, OS4, OSn) to the coil (440). The driving circuit (480) can be connected to a plurality of coils (440) and can transmit the second signals (OS1, OS2, OS3, OS4, OSn) to the plurality of coils (440). The second signals (OS1, OS2, OS3, OS4, OSn) can be generated by the method described with reference to FIGS. 8 to 9D. For example, the second signals (OS1, OS2, OS3, OS4, OSn) can include information about the voltage applied to the coil (440). The button (410) can operate in different ways depending on the type (e.g., voltage waveform, voltage intensity) and order of the second signals (OS1, OS2, OS3, OS4, OSn) transmitted to the coil (440). The second signals (OS1, OS2, OS3, OS4, OSn) may be named "output signals". The second signals (OS1, OS2, OS3, OS4, OSn) may be named "feedback signals".

[0118] According to one embodiment, the second signals (OS1, OS2, OS3, OS4, OSn) transmitted from the driving circuit (480) may be transmitted to the respective coils (440) at different times. For example, the time at which the 2-1 signal (OS1) is transmitted to the first coil (441) and the time at which the 2-2 signal (OS2) is transmitted to the second coil (442) may be different. For example, referring to FIG. 10b, the 2-1 signal (OS1) may be transmitted to the coil (440) before the 2-2 signal (OS2). For example, referring to FIG. 10b, the second-first signal (OS1) transmitted to the first coil (441), the second-second signal (OS2) transmitted to the second coil (442), the second-third signal (OS3) transmitted to the third coil (443), and the second-fourth signal (OS4) transmitted to the fourth coil (444) may be sequentially transmitted to the coils (440) corresponding thereto, respectively. The button (410) may operate according to the order of the second signals (OS1, OS2, OS3, OS4, OSn) transmitted to the plurality of coils (440). For example, referring to FIG. 10b, as the second signal (OS1, OS2, OS3, OS4, OSn) is sequentially transmitted to the first coil (441), the second coil (442), the third coil (443), and the fourth coil (444), the button (410) can vibrate along the haptic direction (S2).

[0119] FIG. 11 is a drawing illustrating the operation of a button assembly (400) according to one embodiment of the present disclosure. The components described with reference to FIG. 11 may be partially or entirely identical to the components described with reference to FIGS. 1 to 10b. The components described with reference to FIG. 11 may be partially or entirely identical to the components described with reference to FIGS. 12 and 14.

[0120] According to one embodiment, the direction (F1, F2) of the magnetic force acting on one of the plurality of magnets (430) (e.g., the first magnet (431) or the second magnet (432)) may be different from the direction (F3, F4) of the magnetic force acting on another of the plurality of magnets (430) (e.g., the third magnet (433) or the fourth magnet (434)). For example, the first coil (441) may generate a repulsive force (F1) with respect to the first magnet (431), and the third coil (443) may generate an attractive force (F3) with respect to the third magnet (433). Referring to Fig. 11, a repulsive force (F1, F2) may be applied to the first and second magnets (431, 432), and an attractive force (F3, F4) may be applied to the third and fourth magnets (433, 434). Referring to Fig. 11, the direction of the current applied to the first and second coils (441, 442) and the direction of the current applied to the third and fourth coils (443, 444) may be opposite to each other. The driving circuit (e.g., the driving circuit (480) of Figs. 10a and 10b) may adjust the direction of the current applied to each of the plurality of coils (440), thereby adjusting the direction of the magnetic force applied to each of the plurality of magnets (430).

[0121] FIG. 12 is a drawing illustrating the operation of a button assembly (400) according to one embodiment of the present disclosure. The components described with reference to FIG. 12 may be partially or entirely identical to the components described with reference to FIGS. 1 to 11. The components described with reference to FIG. 12 may be partially or entirely identical to the components described with reference to FIG. 14.

[0122] According to one embodiment, the gaps (G1, G2, G3, G4) between the magnets (430) and the coils (440) may be formed differently along the second direction (e.g., +Y direction) in which the button (410) extends. For example, the first gap (G1) between the first magnet (431) and the first coil (441) may be greater than the second gap (G2) between the second magnet (432) and the second coil (442). For example, the third gap (G3) between the third magnet (433) and the third coil (443) may be greater than the fourth gap (G4) between the fourth magnet (434) and the fourth coil (444). The magnitude of the first repulsive force formed by the first coil (441) against the first magnet (431) may be greater than the magnitude of the second repulsive force formed by the second coil (442) against the second magnet (432). The magnitude of the third repulsive force formed by the third coil (443) against the third magnet (433) may be greater than the magnitude of the fourth repulsive force formed by the fourth coil (444) against the fourth magnet (434). The driving circuit (e.g., the driving circuit (480) of FIGS. 10A and 10B) may control the magnitude of the magnetic force applied to each of the plurality of magnets (430) by controlling the magnitude of the current applied to each of the plurality of coils (440).

[0123] Referring to FIG. 12, the button (410) can be inclined with respect to a second direction (e.g., +Y direction). The button (410) can have an inclination angle (θ) with respect to the second direction (+Y). A user can press a portion of the button (410). The button (410) can include a first portion (413) that receives a load (W) and a second portion (414) that does not receive a load (W). The first portion (413) can be located farther from the coil (440) than the second portion (414). The magnitude of the first load (W1) at a position corresponding to the first magnet (431) can be greater than the second load (W2) at a position corresponding to the second magnet (432). According to another embodiment of the present disclosure, the repulsive force acting on the first magnet corresponding to the first portion (413) receiving the load (W) may be greater than the repulsive force acting on the second magnet corresponding to the second portion (414) not receiving the load (W). According to another embodiment of the present disclosure, even though a load is applied to the button (410), the equilibrium of the button (410) may be maintained because the repulsive forces applied to the first portion (413) and the second portion (414) of the button (410) are different.

[0124] FIG. 13 is a drawing illustrating the operation of a button assembly (400) according to one embodiment of the present disclosure. The components described with reference to FIG. 13 may be partially or entirely identical to the components described with reference to FIGS. 1 to 12.

[0125] According to one embodiment, the magnitude (F13, F14) of the magnetic force acting on magnets (e.g., the third magnet (433) and the fourth magnet (434)) that are located relatively centrally among the plurality of magnets (430) may be smaller than the magnitude (F11, F16) of the magnetic force acting on magnets (e.g., the first magnet (431) and the sixth magnet (436)) that are located relatively peripherally among the plurality of magnets (430). The magnitude of the magnetic force acting on the plurality of magnets (430) may increase as they get closer to the housing (301). The button (410) may include a first edge (415) and a second edge (416) that are located adjacent to the housing (301). The button (410) may include a center (417) that connects the first edge (415) and the second edge (416). The magnitude (F11, F16) of the magnetic force acting on the magnet (431, 436) corresponding to the first and second edges (415, 416) may be greater than the magnitude (F13, F14) of the magnetic force acting on the magnet (433, 434) corresponding to the center (417). The magnitude of the current applied to the coil (441, 446) corresponding to the first and second edges (415, 416) may be greater than the magnitude of the current applied to the coil (443, 444) corresponding to the center (417). Due to the above-described structure, it is possible to reduce damage to the edge portion (415, 416) that is adjacent to the housing (301) and has a strong repulsive force or frictional force due to the housing (301).

[0126] FIG. 14 is a conceptual diagram illustrating a portion of a cross-sectional view of a button assembly (500) according to one embodiment of the present disclosure. The components described with reference to FIG. 14 may be partially or entirely identical to the components described with reference to FIGS. 1 to 13.

[0127] According to one embodiment, the button assembly (500) may include a magnet (430), a coil (440), a sensor (450), and a button assembly substrate (460). The description of the magnet (430), the coil (440), the sensor (450), and the button assembly substrate (460) described with reference to FIGS. 1 to 13 may be equally applicable.

[0128] In one embodiment, the button assembly (500) may include a button (510). The button (510) may be integral with the housing (301). The button (510) may form a surface of the housing (301). The button (510) may be movable toward the sensor (450). The magnet (430) may be movable together with the button (510). The button (510) may be a portion of the housing (301) comprising a deformable material.

[0129] In one embodiment, the button (510) may include a deformable portion (511). The deformable portion (511) may be movable toward the inside of the housing (301). The deformable portion (511) may include an elastic material. The deformable portion (511) may be movable toward the sensor (450). The button (510) may include a first support portion (512) and a second support portion (513). The first support portion (512) and the second support portion (513) may support the deformable portion (511). The deformable portion (511) may connect the first support portion (512) and the second support portion (513). A plurality of sensors (450) may be arranged between the first support portion (512) and the second support portion (513).

[0130] Electronic devices include a housing and buttons exposed on the exterior of the housing. A user can input an operating signal to the electronic device by pressing the button. The button generates an electrical signal through a physical mechanism. As the button grows in size, it can become unclear which part of the button receives the physical signal. When providing haptic functionality through a button, the haptic action provided by the physical mechanism may be limited.

[0131] A problem to be solved in the present disclosure may be to clearly input a signal through a button.

[0132] The problem to be solved in the present disclosure may be to provide various haptic functions through buttons.

[0133] The problem to be solved in this disclosure is not limited to the problem mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.

[0134] An electronic device according to various embodiments of the present disclosure can increase the accuracy of an input signal through a button by arranging a plurality of sensors along the direction in which the button extends.

[0135] An electronic device according to various embodiments of the present disclosure can provide various haptic functions by arranging a plurality of magnets and a plurality of coils along the direction in which the button extends.
