[0038] FIG. 2 is a drawing illustrating an unfolded state of an electronic device according to various embodiments of the present disclosure. FIG. 3 is a drawing illustrating a folded state of an electronic device according to various embodiments of the present disclosure. FIG. 4 is an exploded perspective view of an electronic device according to various embodiments of the present disclosure.

[0039] Referring to FIGS. 2 and FIGS. 3, in one embodiment, an electronic device (101) may include a foldable housing (300), a hinge cover (e.g., a hinge cover (330) of FIG. 3) covering a foldable portion of the foldable housing (300), and a flexible or foldable display (200) (hereinafter abbreviated as "display" (200)) (e.g., a display device (160) of FIG. 1) disposed within the space formed by the foldable housing (300). According to one embodiment, the surface on which the display (200) is disposed is defined as the front surface (e.g., a first surface (310a) and a third surface (320a)) of the electronic device (101). And, the opposite surface of the front surface is defined as the rear surface (e.g., a second surface (310b) and a fourth surface (320b)) of the electronic device (101). Additionally, the surface surrounding the space between the front and rear is defined as the side of the electronic device (101) (e.g., the first side (311a) and the second side (321a)).

[0040] According to various embodiments, the foldable housing (300) may include a first housing (310), a second housing (320) including a sensor area (324), a first rear cover (380), a second rear cover (390), and a hinge structure (e.g., the hinge structure (302) of FIG. 4). The foldable housing (300) of the electronic device (101) is not limited to the shapes and combinations shown in FIG. 2 and FIG. 3 and may be implemented by other shapes or combinations and / or combinations of parts. For example, in other embodiments, the first housing (310) and the first rear cover (380) may be formed integrally, and the second housing (320) and the second rear cover (390) may be formed integrally. According to various embodiments, the first housing (310) is connected to a hinge structure (302) and may include a first surface (310a) facing a first direction and a second surface (310b) facing a second direction opposite to the first direction. The second housing (320) is connected to a hinge structure (302) and includes a third surface (320a) facing a third direction and a fourth surface (320b) facing a fourth direction opposite to the third direction, and may rotate relative to the first housing (310) about the hinge structure (302). Accordingly, the electronic device (101) may be variable in a folded state or an unfolded state. In the folded state, the first surface (310a) of the electronic device (101) may face the third surface (320a), and in the unfolded state, the third direction may be the same as the first direction. According to one embodiment, when the electronic device (101) is unfolded, the first direction and the third direction may be +Z directions, and the second direction and the fourth direction may be -Z directions. According to one embodiment, when the electronic device (101) is folded, the first direction and the fourth direction may be +Z directions, and the second direction and the third direction may be -Z directions.Below, unless otherwise noted, directions are described based on the unfolded state of the electronic device (101).

[0041] According to various embodiments, the first housing (310) and the second housing (320) are positioned on both sides of the folding axis (A) and may have a shape that is symmetrical with respect to the folding axis (A). As described below, the angle or distance between the first housing (310) and the second housing (320) may vary depending on whether the state of the electronic device (101) is in an unfolded state, a folded state, or an intermediate state. According to one embodiment, unlike the first housing (310), the second housing (320) additionally includes a sensor area (324) in which various sensors are arranged, but may have a mutually symmetrical shape in other areas.

[0042] According to one embodiment, the electronic device (101) may include a structure into which a digital pen (e.g., the electronic pen (1000) of FIG. 5) can be inserted. For example, a hole (323) into which the digital pen (1000) can be inserted may be formed on the side of the first housing (310) or the side of the second housing (320) of the electronic device (101). The digital pen (1000) can be inserted into the hole (323).

[0043] According to various embodiments, as illustrated in FIG. 2, the first housing (310) and the second housing (320) may together form a recess that accommodates the display (200). According to one embodiment, due to the sensor area (324), the recess may have two or more different widths in a direction perpendicular to the folding axis (A).

[0044] According to one embodiment, the recess may have a first width (w1) between a first part (310-1) parallel to the folding axis (A) of the first housing (310) and a third part (320-1) formed at the edge of the sensor area (324) of the second housing (320). The recess may have a second width (w2) formed by a second part (310-2) of the first housing (310) and a fourth part (320-2) parallel to the folding axis A that does not correspond to the sensor area (324) of the second housing (320). In this case, the second width (w2) may be formed to be longer than the first width (w1). As another example, a first part (310-1) of the first housing (310) and a third part (320-1) of the second housing (320) having mutually asymmetric shapes may form a first width (w1) of the recess, and a second part (310-2) of the first housing (310) and a fourth part (320-2) of the second housing (320) having mutually symmetric shapes may form a second width (w2) of the recess. According to one embodiment, the third part (320-1) and the fourth part (320-2) of the second housing (320) may have different distances from the folding axis (A). The width of the recess is not limited to the illustrated example. In another embodiment, the recess may have multiple widths due to the shape of the sensor area (324) or the parts having asymmetric shapes of the first housing (310) and the second housing (320).

[0045] According to various embodiments, at least a portion of the first housing (310) and the second housing (320) may be formed of a metal or non-metal material having a selected size of rigidity to support the display (200). The at least portion formed of the metal material may provide a ground plane of the electronic device (101) and may be electrically connected to a ground line formed on a printed circuit board (e.g., the printed circuit board (360) of FIG. 4).

[0046] According to various embodiments, the sensor area (324) may be formed to have a predetermined area adjacent to one corner of the second housing (320). However, the arrangement, shape, and size of the sensor area (324) are not limited to the illustrated examples. For example, in another embodiment, the sensor area (324) may be provided in any area between the other corner of the second housing (320) or between the top corner and the bottom corner. In one embodiment, components for performing various functions embedded in the electronic device (101) may be exposed to the front of the electronic device (101) through the sensor area (324) or through one or more openings provided in the sensor area (324). In various embodiments, the components may include various types of sensors. The sensor may include, for example, at least one of a front camera, a receiver, or a proximity sensor.

[0047] According to various embodiments, the first rear cover (380) is positioned on one side of the folding axis (A) on the rear of the electronic device (101) and may have a substantially rectangular periphery, for example, and the periphery may be enclosed by the first housing (310). Similarly, the second rear cover (390) is positioned on the other side of the folding axis (A) on the rear of the electronic device (101) and its periphery may be enclosed by the second housing (320).

[0048] According to various embodiments, the first rear cover (380) and the second rear cover (390) may have a substantially symmetrical shape with respect to the folding axis (A-axis). However, the first rear cover (380) and the second rear cover (390) do not necessarily have mutually symmetrical shapes, and in other embodiments, the electronic device (101) may include the first rear cover (380) and the second rear cover (390) of various shapes. In yet another embodiment, the first rear cover (380) may be formed integrally with the first housing (310), and the second rear cover (390) may be formed integrally with the second housing (320).

[0049] According to various embodiments, the first rear cover (380), the second rear cover (390), the first housing (310), and the second housing (320) may form a space in which various components of the electronic device (101) (e.g., a printed circuit board, or a battery) may be placed. According to one embodiment, one or more components may be placed or visually exposed on the rear of the electronic device (101). For example, at least a portion of a sub-display (e.g., the sub-display (270) of FIG. 8) may be visually exposed through the first rear area (382) of the first rear cover (380). In another embodiment, one or more components or sensors may be visually exposed through the second rear area (392) of the second rear cover (390). In various embodiments, the sensors may include a proximity sensor and / or a rear camera.

[0050] According to various embodiments, a front camera exposed to the front of the electronic device (101) through one or more openings provided in the sensor area (324) or a rear camera exposed through a second rear area (392) of the second rear cover (390) may include one or more lenses, an image sensor, and / or an image signal processor. The flash (313) may include, for example, a light-emitting diode or a xenon lamp. In some embodiments, two or more lenses (infrared camera, wide-angle and telephoto lenses) and image sensors may be disposed on one side of the electronic device (101).

[0051] Referring to FIG. 3, the hinge cover (330) may be configured to be positioned between the first housing (310) and the second housing (320) to cover an internal component (e.g., the hinge structure (302) of FIG. 4). According to one embodiment, the hinge cover (330) may be covered by a part of the first housing (310) and the second housing (320) or exposed to the outside depending on the state of the electronic device (101) (flat state or folded state).

[0052] According to one embodiment, as shown in FIG. 2, when the electronic device (101) is in an unfolded state, the hinge cover (330) may be covered by the first housing (310) and the second housing (320) and not exposed. As another example, as shown in FIG. 3, when the electronic device (101) is in a folded state (e.g., a fully folded state), the hinge cover (330) may be exposed to the outside between the first housing (310) and the second housing (320). As yet another example, when the first housing (310) and the second housing (320) are in an intermediate state with a certain angle, the hinge cover (330) may be partially exposed to the outside between the first housing (310) and the second housing (320). However, in this case, the exposed area may be smaller than in the fully folded state. In one embodiment, the hinge cover (330) may include a curved surface.

[0053] According to various embodiments, the display (200) may be placed in a space formed by the foldable housing (300). For example, the display (200) may be seated on a recess formed by the foldable housing (300) and may constitute most of the front surface of the electronic device (101). Accordingly, the front surface of the electronic device (101) may include the display (200), a portion of the first housing (310) adjacent to the display (200), and a portion of the second housing (320). Additionally, the rear surface of the electronic device (101) may include a first rear cover (380), a portion of the first housing (310) adjacent to the first rear cover (380), a second rear cover (390), and a portion of the second housing (320) adjacent to the second rear cover (390).

[0054] According to various embodiments, the display (200) may mean a display in which at least some area can be deformed into a flat or curved surface. According to one embodiment, the display (200) may include a folding area (203), a first area (201) disposed on one side (e.g., the left side of the folding area (203) shown in FIG. 2) with respect to the folding area (203), and a second area (202) disposed on the other side (e.g., the right side of the folding area (203) shown in FIG. 2).

[0055] However, the division of the display (200) shown in FIG. 2 is exemplary, and the display (200) may be divided into multiple areas (e.g., four or more or two) depending on the structure or function. For example, in the embodiment shown in FIG. 2, the areas of the display (200) may be divided by a folding area (203) extending parallel to the y-axis or a folding axis (A-axis), but in other embodiments, the display (200) may be divided based on a different folding area (e.g., a folding area parallel to the x-axis) or a different folding axis (e.g., a folding axis parallel to the x-axis). According to one embodiment, the display (200) may be combined with or placed adjacent to a touch detection circuit, a pressure sensor capable of measuring the intensity (pressure) of the touch, and / or a digitizer configured to detect a magnetic field type stylus pen (e.g., a pen driving circuit (500) in FIG. 5).

[0056] According to various embodiments, the first region (201) and the second region (202) may have a shape that is symmetrical overall with respect to the folding region (203). However, unlike the first region (201), the second region (202) may include a notch cut according to the presence of the sensor region (324), but in other areas, it may have a shape symmetrical to the first region (201). In other words, the first region (201) and the second region (202) may include a part that has a shape symmetrical to each other and a part that has a shape asymmetrical to each other.

[0057] Hereinafter, the operation of the first housing (310) and the second housing (320) and each area of ​​the display (200) according to the state of the electronic device (101) (e.g., flat state, or unfolded state and folded state) will be described.

[0058] According to various embodiments, when the electronic device (101) is in a flat state (e.g., FIG. 2), the first housing (310) and the second housing (320) may be positioned to face in the same direction at an angle of 180 degrees.

The folding region (203) may form a plane with the first region (201) and the second region (202).

[0059] According to various embodiments, when the electronic device (101) is in a folded state (e.g., FIG. 3), the first housing (310) and the second housing (320) may be positioned facing each other. The surface of the first region (201) and the surface of the second region (202) of the display (200) may face each other, forming a narrow angle (e.g., between 0 and 10 degrees). The folding region (203) may be formed of a curved surface having at least a portion having a predetermined curvature.

The surface of the first region (201) and the surface of the second region (202) of the display (200) may form an angle greater than in the folded state and smaller than in the unfolded state. The folding region (203) may be formed of a curved surface having at least a portion of a certain curvature, wherein the curvature may be smaller than in the folded state.

[0061] Referring to FIG. 4, the electronic device (101) may include a foldable housing (300), a display (200), and a substrate (360).

According to one embodiment, a printed circuit board (e.g., a flexible printed circuit board (FPC)) spanning the first mid plate (352) and the second mid plate (354) may be disposed on the bracket assembly (350).

[0064] According to various embodiments, the substrate portion (360) may include a first circuit board (362) disposed on a first mid plate (352) and a second circuit board (364) disposed on a second mid plate (354).

Components for implementing various functions of the electronic device (101) may be mounted on the first circuit board (362) and the second circuit board (364).

[0065] According to various embodiments, the first housing (310) and the second housing (320) may be assembled to each other so as to be coupled to both sides of the bracket assembly (350) when the display (200) is coupled to the bracket assembly (350). According to one embodiment, the first housing (310) may include a first side member (311) that surrounds at least a portion of the side of the first mid plate (352), and the second housing structure (310) may include a second side member (321) that surrounds at least a portion of the side of the second mid plate (354). The first housing (310) may include a first rotational support surface (312), and the second housing (320) may include a second rotational support surface (322) corresponding to the first rotational support surface (312). The first rotational support surface (312) and the second rotational support surface (322) may include a curved surface corresponding to the curved surface included in the hinge cover (330). According to one embodiment, the first side member (311) may include a first side (311a) perpendicular to the first direction or the second direction, surrounding at least a portion between the first surface (310a) and the second surface (310b). According to one embodiment, the second side member (321) may include a second side perpendicular to the third direction or the fourth direction, surrounding at least a portion between the third surface (320a) and the fourth surface (320b).

[0066] According to one embodiment, the first rotational support surface (312) and the second rotational support surface (322) cover the hinge cover (330) when the electronic device (101) is in an unfolded state (e.g., the electronic device of FIG. 2), and the hinge cover (330) may not be exposed to the rear surface of the electronic device (101) or may be exposed minimally. As another example, when the electronic device (101) is in a folded state (e.g., the electronic device of FIG. 3), the first rotational support surface (312) and the second rotational support surface (322) rotate along the curved surface included in the hinge cover (330) so that the hinge cover (330) may be exposed to the rear surface of the electronic device (101) to the maximum extent.

[0068] FIG. 5 is an exploded perspective view of an electronic device including a pen driving circuit according to various embodiments of the present disclosure. FIG. 6 is a cross-sectional view of plane AA' of FIG. 4.

[0069] Referring to FIGS. 5 and 6, the electronic device (101) may include a display (200), a foldable housing (300), a magnet array (400), and a pen driving circuit (500).

[0070] According to various embodiments, the foldable housing (300) may include a window member (370). The window member (370) may be formed of a material in which at least a portion is substantially transparent. For example, the window member may be formed of ultra-thin glass (UTG) or a polyimide film. A display panel (280) may be exposed to the outside of the electronic device (101) through the window member (370). According to one embodiment, the window member (370) may form at least a portion of the outer surface of the electronic device (101). According to one embodiment, the electronic device (101) may include a coating layer (372) disposed on the window member (370). The coating layer (372) may protect the window member (370) and the display (200) from external impacts of the electronic device (101).

[0071] According to various embodiments, the display (200) may include configurations for outputting an image to the outside of the electronic device (101). For example, the display (200) may include at least one of a display panel (280), a polarizing film (210) disposed between the display panel (280) and a window member (370), a cushion support layer (220) disposed below the display panel (280), a cushion layer (230) disposed below the cushion support layer (220), a shielding sheet (240) disposed below the cushion layer (230), a support plate (250) disposed below the shielding sheet (240), and a heat dissipation sheet (260) disposed below the support plate (250).

[0072] According to various embodiments, the electronic device (101) may include a pen driving circuit (500) configured to transmit an electromagnetic field signal. For example, the resonance circuit of the electronic pen (1000) connected to the electronic device (101) via a wireless communication module (e.g., the wireless communication module (192) of FIG. 1) may resonate based on an electromagnetic field signal generated from the pen driving circuit (500) of the electronic device (101), and may radiate an electromagnetic resonance (EMR) input signal by resonance. The electronic device (101) may determine the position of the electronic pen (1000) on the electronic device (101) using the electromagnetic resonance input signal. For example, the electronic device (101) can determine the position of the electronic pen (1000) based on the magnitude of the induced electromotive force (e.g., output current) generated by the electromagnetic resonance input signal in each of the plurality of channels (e.g., plurality of loop coils) within the pen driving circuit (500). Meanwhile, although the electronic device (101) and the electronic pen (1000) have been described above as operating based on the EMR method, this is merely illustrative, and the electronic device (101) may also generate an electric field-based signal based on the ECR (electrically coupled resonance) method.

[0073] According to various embodiments, the resonant circuit of the electronic pen (1000) may be resonated by an electric field. The electronic device (101) may detect potentials in multiple channels (e.g., electrodes) due to resonance in the electronic pen (1000) and may determine the position of the electronic pen (1000) based on the potentials. The electronic pen (1000) may be implemented in an active electrostatic (AES) manner, and those skilled in the art will understand that there are no limitations on the type of implementation. According to one embodiment, the electronic device (101) may detect the electronic pen (1000) based on a change in capacitance (self-capacitance or mutual capacitance) associated with at least one electrode of the touch panel. In this case, the electronic pen (1000) may not include a resonant circuit.

[0074] According to various embodiments, the pen driving circuit (500) may be placed below the display panel (280). According to one embodiment, the pen driving circuit (500) may be placed between the cushion layer (230) and the shielding sheet (240). According to another embodiment, the pen driving circuit (500) may be placed between the support plate (250) together with the shielding sheet (240). According to yet another embodiment, the pen driving circuit (500) may be placed between the support plate (250) and the heat dissipation sheet (260) together with the shielding sheet (240). Again according to yet another embodiment, the pen driving circuit (500) may be placed below the heat dissipation sheet (260). According to various embodiments, the magnet array (400) may be placed at the edge of the electronic device (101). For example, a first magnet array (e.g., the first magnet array (410) of FIG. 7) may be placed on the edge of the first housing (310), and a second magnet array (e.g., the second magnet array (420) of FIG. 7) may be placed on the edge of the second housing (320). According to one embodiment, a shielding sheet (240) may be placed below (e.g., in the -Z direction) the pen driving circuit (500).

[0075] According to various embodiments, the magnet array (400) can reduce the gap between the first housing (310) and the second housing (320) formed by the repulsive force generated in the first housing (310) and the second housing (320) when the electronic device (101) is folded. For example, when the electronic device (101) is in a folded state, the magnet array (400) can generate an attractive force between the first housing (310) and the second housing (320) by forming a magnetic field that is substantially the same direction in which the magnet array (400) placed in the first housing (310) and the magnet array (400) placed in the second housing (320) form a magnetic field.

[0076] According to various embodiments, the magnet array (400) may be formed from various materials. For example, the magnet array (400) may include neodymium (Nd), iron (Fe), and boron (B).

[0080] According to various embodiments, the magnet array (400) may be positioned at the perimeter or edge of the electronic device (101). For example, the first magnet array (410) may be positioned adjacent to the first side member (311), and the second magnet array (420) may be positioned adjacent to the second side member (321).

[0081] According to various embodiments, the electronic device (101) may include a deco member (304) that forms at least a portion of the edge of the electronic device (101). According to one embodiment, when the electronic device (101) is viewed from above (e.g., in the +Z direction), the deco member (304) may surround at least a portion of the first surface (310a) or at least a portion of the second surface (320a). According to one embodiment, the deco member (304) may form at least a portion of the first side (311a) or the second side (321a).

[0082] According to various embodiments, the first magnet array (410) may be placed within the first housing (310). According to one embodiment, the first magnet array (410) may be placed between the first surface (310a) and the second surface (310b) of the first housing (310) in the height direction (e.g., Z-axis direction), and between the first side (311a) and the hinge structure (302) in the horizontal direction (e.g., X-axis direction). According to one embodiment, the first magnet array (410) may be placed adjacent to the deco member (304). For example, when viewing the electronic device (101) from above (+Z direction), at least a portion of the first magnet array (410) may overlap with at least a portion of the deco member (304).

[0083] According to various embodiments, the second magnet array (420) may be placed within the second housing (320). According to one embodiment, the second magnet array (420) may be placed between the third face (320a) and the fourth face (320b) of the second housing (320) in the height direction (e.g., Z-axis direction), and between the second side (321a) and the hinge structure (302) in the horizontal direction (e.g., X-axis direction). According to one embodiment, the second magnet array (420) may be placed adjacent to the deco member (304). For example, when viewing the electronic device (101) from above (e.g., +Z direction), at least a portion of the second magnet array (420) may overlap with at least a portion of the deco member (304).

[0084] According to various embodiments, at least a portion of the magnet array (400) may be placed below the display (200). For example, when the magnet array (400) is viewed in a second direction (-Z direction), at least a portion of the magnet array (400) may overlap with the display (200).

[0085] According to various embodiments, the electronic device (101) may include a sub-display (270). The sub-display (270) may be visually exposed through a first rear area (e.g., the first rear area (382) of FIG. 2). At least a portion of the first magnet array (410) may be positioned between the display (200) and the sub-display (270).

[0087] FIG. 9a is a front view of an electronic device having a magnet array arranged in an unfolded state according to various embodiments of the present disclosure, and FIG. 9b is a perspective view of an electronic device having a magnet array arranged in a folded state according to various embodiments of the present disclosure. FIG. 10 is a perspective view of an electronic device including a plurality of magnet arrays according to various embodiments of the present disclosure. FIG. 11 is a perspective view of an electronic device including a magnetic material according to various embodiments of the present disclosure. FIG. 12a, FIG. 12b, FIG. 12c, and FIG. 12d are schematic diagrams of a magnet array according to various embodiments of the present disclosure.

[0088] Referring to FIGS. 9a, 9b, and 10, the magnet array (400) may include a plurality of magnets. The configuration of the magnet array (400) in FIGS. 9a, 9b, and 10 may be all or partly the same as the configuration of the magnet array (400) in FIGS. 7 and 8.

[0089] According to various embodiments, the magnet array (400) may be arranged substantially parallel to the folding axis (A axis). For example, the magnet array (400) may include a plurality of magnets arranged along the axial direction (Y-axis direction).

[0090] According to various embodiments, when the electronic device (101) is folded with respect to a folding axis (A-axis) (e.g., FIG. 9b), the first magnet array (410) and the second magnet array (420) may correspond to each other. For example, the distance between the first magnet array (410) and the folding axis (A-axis) may be substantially the same as the distance between the second magnet array (420) and the folding axis (A-axis). According to one embodiment, when viewing the electronic device (101) in a folded state from a first direction, at least a portion of the first magnet array (410) may overlap with at least a portion of the second magnet array (420). According to one embodiment, the first magnet array (410) and the second magnet array (420) may be arranged substantially parallel in the axial direction (Y-axis direction). According to one embodiment, when the electronic device (101) is in a folded state (e.g., FIG. 9b), the first magnet array (410) can be magnetically connected to the second magnet array (420) using a magnetic field. For example, the first magnet array (410) and the second magnet array (420) can be provided with an attractive force toward each other using a third magnetic field (410-3) formed by a combination of the first magnetic field (410-1) of the first magnet array (410) and the second magnetic field (410-2) of the second magnet array (420). According to one embodiment, unintended unfolding by the user due to the repulsive force of the display (e.g., the display (200) of FIG. 4) can be reduced or prevented by the third magnetic field (410-3) of the first magnet array (410) and the second magnet array (420).

[0091] According to various embodiments, the magnet array (400) may be arranged in a first designated arrangement. The first designated arrangement may be defined as a magnet array in which the magnitude of the magnetic field in the height direction (e.g., Z-axis direction) of the magnet array (400), which is substantially parallel to the folding axis (A-axis), is greater than the magnitude of the magnetic field in the horizontal direction (e.g., X-axis direction). According to one embodiment, the first magnet array (410) may generate a first magnetic field (410-1). With respect to the center axis (e.g., Y-axis) of the first magnet array (410) of the unfolded electronic device (101), the magnitude of the first magnetic field (410-1) formed in the first direction (+Z direction) may be greater than the magnitude of the first magnetic field (410-1) formed in the second direction (-Z direction), the fifth direction (+Y direction), or the sixth direction (-Y direction). According to another embodiment, the second magnet array (420) can generate a second magnetic field (420-1). With respect to the central axis (e.g., Y-axis) of the second magnet array (420) of the electronic device (101) in an unfolded state, the magnitude of the second magnetic field (420-1) formed in the third direction (+Z direction) may be greater than the magnitude of the second magnetic field (420-1) formed in the fourth direction (-Z direction), the fifth direction (+Y direction), or the sixth direction (-Y direction). According to various embodiments, the first designated array may be a three-dimensional multipolar array. According to one embodiment, the three-dimensional multipolar array may include a Halbach array. In one side of the magnet array (400) arranged in the above three-dimensional multipolar array (e.g., the ninth side (410c) of FIG. 17), the magnetic field may be superimposed and increased, and in another side (e.g., the ninth side (410d) of FIG. 17), the magnetic field may be canceled out and decreased.

[0092] According to various embodiments, the magnet array (400) may include a plurality of magnets forming various magnetic field directions.

[0093] According to one embodiment, the first magnet array (410) may include a first-1 magnet (411), a first-2 magnet (412), a first-3 magnet (413), and a first-4 magnet (414) that each form a magnetic field directed in a different direction. For example, the first-1 magnet (411) may have its N pole positioned in the first direction (+Z direction) of the first-1 magnet (411) to form a magnetic field directed toward a first surface (e.g., the first surface (310a) of FIG. 2), and the first-2 magnet (412) may have its N pole positioned in the second direction (-Z direction) of the first-2 magnet (412) to form a magnetic field directed toward a second surface (e.g., the second surface (310b) of FIG. 2). The N pole of the first-third magnet (413) is located in the sixth direction (-Y direction) of the first-third magnet, and the first-third magnet (413) can form a magnetic field directed toward the end of the sixth direction (-Y direction) of the first magnet array (410). The N pole of the first-fourth magnet (414) is located in the fifth direction (+Y direction) of the first-fourth magnet, and the first-fourth magnet (414) can form a magnetic field directed toward the end of the fifth direction (+Y direction) of the first magnet array (410). According to one embodiment, the magnets (411, 412, 413, 414) of the first magnet array (410) can each be combined while in direct contact with other magnets (411, 412, 413, 414). For example, a separate non-magnetic material (e.g., a block of metal or resin) for coupling may not be located between the magnets (411, 412, 413, 414) and other magnets (411, 412, 413, 414).

[0111] FIG. 14 is a front view of an electronic device including a guide member according to various embodiments of the present disclosure. FIG. 15 is a schematic diagram illustrating the magnetic field of a magnet array according to one embodiment of the present disclosure.

[0112] Referring to FIGS. 14 and 15, the electronic device (101) may include a magnet array (400) and a guide member (700). The configuration of the magnet array (400) in FIGS. 14 and 15 may be all or partly the same as the configuration of the magnet array (400) in FIGS. 7 and 8. According to various embodiments, the magnet array (400) may include a surface facing the edge of the electronic device (101) (e.g., a first side (311a) or a second side (321a)). For example, the first magnet array (410) may include a fifth surface (410a) facing the first side (311a) of the first housing (310) and a sixth surface (410b) opposite the fifth surface, and the second magnet array (420) may include a seventh surface (420a) facing the second side (321a) of the second housing (320) and an eighth surface (420b) opposite the seventh surface.

[0114] According to various embodiments, the guide member (700) may be formed in a structure capable of controlling the direction of the magnetic field of the magnet array (400). For example, when the electronic device (101) is in a folded state, the third distance (d3), which is the distance between the first guide member (710) and the second guide member (720), may be shorter than the fourth distance (d4), which is the distance between the first magnet array (410) and the second magnet array (420). The first magnetic field (410-1) formed in the first magnet array (410) may be transmitted along the first guide member (710) to the second guide member (720) and the second magnet array (420). In FIG. 15, the magnetic field formed at the N pole of a part of the first magnet array (410) (e.g., the first-1 magnet (411)) is shown to be transferred to the S pole of a part of the second magnet array (420) (e.g., the second-1 magnet (421)), but in other embodiments (not shown), the magnetic field formed at the N pole of the second magnet array (420) may be transferred to the S pole of the first magnet array (410).

According to another embodiment, the guide member (700) can increase the proportion of the magnetic field of the second magnet array (420) that is transmitted to the first magnet array (410). For example, the guide member (700) can guide the direction of the magnetic field such that the magnitude of the magnetic field of the magnet array (400) facing the height direction (e.g., Z-axis direction) is greater than the magnitude of the magnetic field of the magnet array (400) facing the horizontal direction (e.g., X-axis direction).

[0116] According to various embodiments, a guide member (700) may be disposed on a magnet array (400). According to one embodiment, a first guide member (710) may be disposed on the fifth side (410a) of the first magnet array (410) facing the first side (311a) (seventh direction (-X direction)), and a second guide member (720) may be disposed on the seventh side (420a) of the second magnet array (420) facing the second side (321a) (seventh direction (-X direction)). According to one embodiment, the first guide member (710) may be disposed between the first side (311a) of the first housing (310) and the first magnet array (410), and the second guide member (720) may be disposed between the second side (321a) of the second housing (320) and the second magnet array (420).

According to one embodiment, the first guide member (710) may cover a portion of the fifth surface (410a) of the first magnet array (410), and the second guide member (720) may cover a portion of the seventh surface (420a) of the second magnet array (420). For example, the first guide member (710) may extend to a virtual boundary dividing the N pole and the S pole of the first magnet array (410) to cover the N pole region or the S pole region, and the second guide member (720) may extend to a virtual boundary dividing the N pole and the S pole of the second magnet array (420) to cover the N pole region or the S pole region.

[0118] According to various embodiments, the guide member (700) may be placed on at least some of the plurality of magnets of the magnet array (400). For example, the guide member (700) may be placed on a magnet that forms a magnetic field toward the front (e.g., first side or third side) or rear (e.g., second side or fourth side) of the electronic device (101). According to one embodiment, the first guide member (710) may be placed on at least some of the first-1 magnet (411) and the first-2 magnet (412), and the second guide member (720) may be placed on at least some of the second-1 magnet (421) and the second-2 magnet (422).

For example, when the electronic device (101) is in a folded state, the magnet array (900) may form a first magnetic field region (A1) that generates an attractive force between the first magnet array (910) and the second magnet array (920). The first magnetic field region (A1) may be a plurality of magnetic fields transmitted from the first-1 magnet (911) to the second-1 magnet (921) through the first guide member (710), the second guide member (720), and the empty space. The size of the first magnetic field region (A1) in the height direction (e.g., Z-axis direction) may be larger than the size in the width direction (e.g., X-axis direction). According to another embodiment, the second magnetic field (920-1) can be transmitted from a magnet of the second magnet array (920) (e.g., second-2 magnet (922)) to a magnet of the first magnet array (910) (e.g., first-2 magnet (912)) through the second guide member (720) and the first guide member (710).

According to one embodiment, the first-2 magnetic field (912a) formed by the first magnet array (910) may be formed to form a first designated angle (θ1) with the second surface (310b) of the first housing (310). For example, the first-2 magnet (912) may transmit the first-2 magnetic field (912a) to the second surface (310b) at the first designated angle (θ1). The N pole of the first-second magnet (912) may be located along the 6th surface (910b) and the 10th surface (910d) of the first magnet array (910), and the S pole of the first-second magnet (912) may be located along the 5th surface (910a) and the 9th surface (910c) of the first magnet array (910).

[0125] According to various embodiments, the second magnet array (920) may form a magnetic field directed toward the third surface (320a) and the fourth surface (320b) of the second housing (320) at an inclined angle. According to one embodiment, the second-1 magnetic field (921a) formed by the second magnet array (920) may be formed to form a second designated angle (θ2) with the fourth surface (320b) of the second housing (320). The second-1 magnet (921) may be configured so that the second-1 magnetic field (921a) is transmitted to the third surface (320a) at the second designated angle (θ2). For example, the N pole of the second-1 magnet (921) may be positioned along the eighth surface (920b) and the eleventh surface (920c) of the second magnet array (920). The above second-1 magnetic field (921a) may overlap with the first-1 magnetic field (911a) to increase the attractive force formed between the first magnet array (910) and the second magnet array (920).
