The storage space may be defined as an internal space of the electronic device (101) for storing a digital pen (e.g., a digital pen (300) of FIGS. 4A to 4C).

[0181] According to one embodiment, the storage space may be formed inside the second housing (220). The storage space may be formed between the second plate (223) of the second housing (220) and the second rear cover (e.g., the second rear cover (225) of FIG. 5).

[0182] For example, the storage space may be formed in the first region (S1) of the second housing (220). According to one embodiment, the first region (S1) may be disposed adjacent to the second-first side (221a). For example, the first region (S1) may be an region disposed closer to the second-first side (221a) than the folding axis (A) (e.g., the folding axis (A) of FIG. 2). In addition, the first region (S1) may be defined as an region disposed adjacent to one side (e.g., a portion facing the +X direction of FIGS. 5 to 6) of the second battery (e.g., the second battery (272) of FIG. 5).

[0183] For example, the storage space may be formed in the second region (S2) of the second housing (220). According to one embodiment, the second region (S2) may be disposed adjacent to the folding axis (A).

[0184] For example, the storage space may be formed in the third region (S3) of the first housing (210). According to one embodiment, the third region (S3) may be disposed adjacent to the folding axis (A). For example, the third region (S3) may be an region disposed closer to the folding axis (A) than the first-first side (211a).

According to one embodiment, the fourth area (S4) may be disposed adjacent to the 1-1 side surface (211a). For example, the fourth area (S4) may be an area disposed closer to the 1-1 side surface (211a) than the folding axis (A) (e.g., the folding axis (A) of FIG. 2). In addition, the fourth area (S4) may be defined as an area disposed adjacent to one side (e.g., a portion facing the -X direction of FIGS. 5 to 6) of the first battery (e.g., the first battery (271) of FIG. 5).

[0186] According to one embodiment, the electronic device (101) may include a storage space (e.g., storage space (228) of FIG. 4A) formed in any one of the first region (S1) to the fourth region (S4) described above. According to one embodiment, the storage space may be formed inside the first housing (210) or the second housing (220) of the electronic device (101).

[0187] According to one embodiment, when the storage space is formed in either the first area (S1) or the second area (S2), the storage space may not overlap with the second battery (e.g., the second battery (272) of FIG. 5) in the thickness direction (e.g., the Z-axis direction of FIGS. 5 and 6) of the electronic device (101) when the electronic device (101) is unfolded (e.g., FIG. 2). For example, the thickness direction (e.g., the Z-axis direction of FIGS. 5 and 6) may be defined as a direction (or an opposite direction) from the second display area (e.g., the second display area (252) of FIG. 5) toward the second rear cover (e.g., the second rear cover (225) of FIG. 5) when the electronic device (101) is unfolded (e.g., FIG. 2). According to one embodiment, when the storage space is formed in either the first region (S1) or the second region (S2), the storage space may overlap at least a portion of the second battery (e.g., the second battery (272) of FIG. 5) in the width direction (e.g., the X-axis direction of FIGS. 5 and 6) of the electronic device (101) when at least a portion of the electronic device (101) is unfolded (e.g., FIG. 2). For example, the width direction (e.g., the X-axis direction of FIGS. 5 and 6) may be defined as a direction (or an opposite direction) toward the folding axis (A) from the second-first side surface (221a).

[0188] According to one embodiment, when the storage space is formed in either the third area (S3) or the fourth area (S4), the storage space may not overlap the first battery (e.g., the first battery (271) of FIG. 5) in the thickness direction (e.g., the Z-axis direction of FIGS. 5 and 6) of the electronic device (101) when the electronic device (101) is unfolded (e.g., FIG. 2). For example, the thickness direction (e.g., the Z-axis direction of FIGS. 5 and 6) may be defined as a direction (or an opposite direction) from the first display area (e.g., the first display area (251) of FIG. 5) toward the first rear cover (e.g., the first rear cover (215) of FIG. 5) when the electronic device (101) is unfolded (e.g., FIG. 2). According to one embodiment, when the storage space is formed in either the third region (S3) or the second region (S2), the storage space may overlap at least a portion of the first battery (e.g., the first battery (271) of FIG. 5) in the width direction (e.g., the X-axis direction of FIGS. 5 and 6) of the electronic device (101) when at least a portion of the electronic device (101) is unfolded (e.g., FIG. 2).

[0197] FIG. 11b is a graph showing the strength of a magnetic field detected by a Hall sensor when a digital pen changes from a stored state to an unstored state according to one embodiment of the present disclosure.

[0198] The embodiments of FIGS. 7 to 11b may be combined with the embodiments of FIGS. 1 to 6, or the embodiments of FIGS. 12 to 15.

[0199] Referring to FIGS. 7 to 11B, an electronic device (101) (e.g., the electronic device (101) of FIGS. 1 to 6) may include a first housing (210), a second housing (220), a first printed circuit board (241), a hall sensor (245), a first magnet (291), a second magnet (292), a digital pen (300), or a coil (323).

[0200] The configuration of the first housing (210), the second housing (220), or the first printed circuit board (241) of FIGS. 7 to 11b may be partially or entirely identical to the configuration of the first housing (210), the second housing (220), or the first printed circuit board (241) of FIGS. 5 to 6. The configuration of the digital pen (300) or the coil (323) of FIGS. 7 to 11b may be partially or entirely identical to the configuration of the digital pen (300) or the coil (323) of FIGS. 4a to 4c.

[0201] According to one embodiment, a hinge structure (e.g., hinge structure (231) of FIG. 5) can relatively rotatably connect the first housing (210) and the second housing (220).

[0202] According to one embodiment, the digital pen (300) may be configured to be stored in the first housing (210) of the electronic device (101). For example, the digital pen (300) may be configured to be stored in the first storage space (e.g., the first storage space (S1) of FIG. 6) of the electronic device (101). However, the location where the digital pen (300) is stored in the electronic device (101) is exemplary, and the digital pen (300) may be stored in another storage space (e.g., the second to fourth storage spaces (S2 to S4) of FIG. 6) of the electronic device (101).

[0203] According to one embodiment, the digital pen (300) can be stored in the first housing (210) of the electronic device (101) from the outside of the electronic device (101) by the user. In addition, the digital pen (300) can be taken out of the electronic device (101) from the state in which it is stored in the first housing (210) of the electronic device (101) by the user. For example, the digital pen (300) can be removed from the outside of the first housing (210).

[0204] According to one embodiment, the electronic device (101) may include a first magnet (291) or a second magnet (292). The first magnet (291) may be disposed in the first housing (210). For example, the first magnet (291) may be disposed inside the first housing (210) and may be positioned adjacent to a first-first side surface (e.g., the first-first side surface (211a) of FIGS. 5 and 6) of the first housing (210). The second magnet (292) may be disposed in the second housing (220). For example, the second magnet (292) may be disposed inside the second housing (220) and may be positioned adjacent to a second-first side surface (e.g., the second-first side surface (221a) of FIGS. 5 and 6) of the second housing (220).

[0205] According to one embodiment, the first magnet (291) and the second magnet (292) may be arranged to face each other when the electronic device (101) is in a folded state (e.g., FIG. 2 or FIG. 8B). For example, when the electronic device (101) is in a folded state (e.g., FIG. 8B), the first magnet (291) may overlap the second magnet (292) based on the direction from the first rear cover (e.g., the first rear cover (215) of FIG. 6 or FIG. 8B) toward the second rear cover (e.g., the second rear cover (225) of FIG. 6 or 8B). For example, when the electronic device (101) is in an unfolded state (e.g., FIG. 2 or FIG. 8a), the second magnet (291) may be positioned corresponding to the first magnet (291) with respect to the hinge structure (e.g., the hinge structure (231) of FIG. 5) as the center. According to one embodiment, the first magnet (291) and / or the second magnet (292) may include a permanent magnet or a Halbach array magnet. According to one embodiment, when the electronic device (101) is in a folded state, the electronic device (101) may be maintained in the folded state by the attractive force acting between the first magnet (291) and the second magnet (292).

[0206] According to one embodiment, the electronic device (101) may include a Hall sensor (245) disposed or mounted on a first printed circuit board (241). According to one embodiment, the Hall sensor (245) is a sensor whose voltage changes depending on the intensity of a magnetic field and may be configured to detect a change in the intensity of a magnetic field through the Hall effect. The first printed circuit board (241) may be defined and / or referred to as a circuit board (241). A processor (e.g., the processor (120) of FIG. 1) and / or a memory (e.g., the memory (130) of FIG. 1) may be disposed or mounted on the circuit board (241).

[0207] According to one embodiment, when the electronic device (101) is unfolded (e.g., FIG. 2, FIG. 7, or FIG. 8a), the Hall sensor (245) may be disposed between the first magnet (291) and the second magnet (292) in the width direction of the electronic device (101) (e.g., the X-axis direction of FIG. 7), but is not limited thereto and may be disposed at various positions. The Hall sensor (245) may be disposed adjacent to the first magnet (291). For example, the Hall sensor (245) may be disposed adjacent to the first magnet (291) and relatively far from the second magnet (292) when the electronic device (101) is unfolded (e.g., FIG. 2, FIG. 7, or FIG. 8a).

[0208] In one embodiment, the Hall sensor (245) may be configured to detect a change in an electrical signal according to the proximity or distance of a first magnet (291), a second magnet (292), or a coil (323) having a magnetic force. The Hall sensor (245) may measure, sense, or detect a magnetic force value (e.g., the strength of a magnetic field). The Hall sensor (245) may transmit (or transfer) information about the measured magnetic force value (e.g., the strength of a magnetic field) to a processor (e.g., the processor (120) of FIG. 1).

[0209] According to one embodiment, the Hall sensor (245) can measure the strength of a magnetic field in three directions based on the Hall sensor (245). For example, the Hall sensor (245) can measure the strength of a magnetic field in the X-axis direction, the Y-axis direction, and the Z-axis direction, which are orthogonal to each other. The Hall sensor (245) can be configured to measure the strength of a magnetic field in the X-axis direction, the Y-axis direction, and the Z-axis direction, respectively.

[0210] According to one embodiment, the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may be configured to recognize or determine the current state of the electronic device (101) based on information about the strength of the magnetic field provided from the Hall sensor (245). For example, the processor of the electronic device (101) may be configured to recognize or determine, based on information about the strength of the magnetic field, an unfolded state of the electronic device (101) (e.g., FIG. 2 or FIG. 8a), a folded state of the electronic device (101) (e.g., FIG. 3 or FIG. 8b), a state in which the digital pen (300) is not stored in the electronic device (101) (or the first housing (310)) (e.g., FIG. 10a), or a state in which the digital pen (300) is stored in the electronic device (101) (or the first housing (310)) (e.g., FIG. 10b).

[0211] According to one embodiment, when the digital pen (300) is housed inside the first housing (210) in an unfolded state of the electronic device (101) (e.g., FIG. 2, FIG. 7, or FIG. 8a), the coil (323) of the digital pen (300) may be disposed between the first magnet (291) and the second magnet (292) with respect to the width direction of the electronic device (101) (e.g., the X-axis direction of FIG. 7). In addition, the coil (323) of the digital pen (300) may overlap the Hall sensor (245) with respect to the height direction of the electronic device (101) (e.g., the Y-axis direction of FIG. 7), but is not limited thereto.

[0212] Fig. 8a is a cross-sectional view of the electronic device (101) in an unfolded state, and Fig. 8b is a cross-sectional view of the electronic device (101) in a folded state.

[0213] Referring to FIGS. 8A and 8B, the first magnet (291) may be positioned between the display (250) (e.g., the display (250) of FIG. 5) and the first rear cover (215) (e.g., the first rear cover (215) of FIG. 5). For example, the first magnet (291) may be positioned between the first display area (e.g., the first display area (250) of FIG. 5) and the first rear cover (215).

[0214] According to one embodiment, the second magnet (292) may be positioned between the display (250) and the second rear cover (225) (e.g., the second rear cover (225) of FIG. 5). For example, the second magnet (225) may be positioned between the second display area (e.g., the second display area (250) of FIG. 5) and the second rear cover (225).

[0215] According to one embodiment, when the electronic device (101) is unfolded (e.g., FIG. 8a), the Hall sensor (245) may be positioned within a magnetic field range (291a) formed by the first magnet (291). Since the second magnet (292) is positioned relatively far from the Hall sensor (245), the magnetic field formed by the second magnet (292) may not substantially affect the Hall sensor (245). For example, the Hall sensor (245) may not be positioned within a magnetic field range formed by the second magnet (292). When the electronic device (101) is unfolded (e.g., FIG. 8a), the Hall sensor (245) may be positioned within a magnetic field range (291a) formed by the first magnet (291), and the intensity of the magnetic field detected by the Hall sensor (245) may be the first magnetic field value.

[0216] According to one embodiment, when the electronic device (101) is in a folded state (e.g., FIG. 8b), the Hall sensor (245) may be positioned within a magnetic field range (291a) formed by the first magnet (291) and a magnetic field range (291b) formed by the second magnet (292). Compared to an unfolded state (e.g., FIG. 8b) of the electronic device (101), the second magnet (292) in the folded state (e.g., FIG. 8b) is positioned relatively closer to the Hall sensor (245) than the second magnet (292) in the unfolded state (e.g., FIG. 8a) of the electronic device (101), and therefore, the magnetic field formed by the second magnet (292) may substantially affect the Hall sensor (245). For example, the Hall sensor (245) may be placed within the magnetic field range (291b) formed by the second magnet (292). When the electronic device (101) is folded (e.g., FIG. 8b), the Hall sensor (245) may be positioned overlappingly within the magnetic field range (291a) formed by the first magnet (291) and the magnetic field range (291b) formed by the second magnet (292), and the intensity of the magnetic field detected by the Hall sensor (245) may be a second magnetic field value greater than the first magnetic field value.

[0217] According to one embodiment, when the electronic device (101) is in an unfolded state (e.g., FIG. 8a), the Hall sensor (245) may be configured to detect the first magnet (291). When the electronic device (101) is in a folded state (e.g., FIG. 8b), the Hall sensor (245) may be configured to detect the first magnet (291) and the second magnet (292). When the electronic device (101) is in an unfolded state (e.g., FIG. 8a), the intensity value of the magnetic field detected by the Hall sensor (245) may be different from the intensity value of the magnetic field detected by the Hall sensor (245) when the electronic device (101) is in a folded state (e.g., FIG. 8b).

[0218] FIG. 9A is a graph showing the intensity of a magnetic field detected by a Hall sensor (245) when an electronic device (101) changes from an unfolded state (e.g., FIG. 8A) to a folded state (e.g., FIG. 8B), and FIG. 9B is a graph showing the intensity of a magnetic field detected by a Hall sensor (245) when an electronic device (101) changes from a folded state (e.g., FIG. 8B) to an unfolded state (e.g., FIG. 8A). The horizontal axis of FIGS. 9A and 9B represents time (t), and the vertical axis represents the intensity of the magnetic field (G).

[0219] Referring to FIGS. 8A, 8B, and 9A, the intensity of a magnetic field detected by the Hall sensor (245) when the electronic device (101) changes from an unfolded state (e.g., FIG. 8A) to a folded state (e.g., FIG. 8B) will be described. Before the time point (t1) at which the magnetic field of the second magnet (292) is detected, the Hall sensor (245) can detect only the magnetic field by the first magnet (291), and the intensity of the magnetic field detected by the Hall sensor (245) can be the first magnetic field value (g1). When the electronic device (101) changes to a folded state within a predetermined range, the Hall sensor (245) can detect the magnetic field of the second magnet (292). Before the time point (t2) when the electronic device (101) is completely transformed into a folded state (e.g., FIG. 8b), the Hall sensor (245) can gradually get closer to the second magnet (292), and the intensity of the magnetic field detected by the Hall sensor (245) can gradually increase. After the time point (t2) when the electronic device (101) is completely transformed into a folded state (e.g., FIG. 8b), the Hall sensor (245) can be positioned within the range of the magnetic fields of the first magnet (291) and the second magnet (292), and the intensity of the magnetic field detected by the Hall sensor (245) can be a second magnetic field value (g2) greater than the first magnetic field value (g1).

[0220] Referring to FIGS. 8A, 8B, and 9B, the intensity of a magnetic field detected by the Hall sensor (245) when the electronic device (101) changes from a folded state (e.g., FIG. 8B) to an unfolded state (e.g., FIG. 8A) will be described. Before a time point (t3) at which the second magnet (292) moves relatively far from the Hall sensor (245), the Hall sensor (245) may be positioned within the range of the magnetic fields of the first magnet (291) and the second magnet (292), and the intensity of the magnetic field detected by the Hall sensor (245) may be a third magnetic field value (g3). The third magnetic field value (g3) may be substantially the same as the second magnetic field value (g2) (e.g., the second magnetic field value (g2) of FIG. 9A). Before the time point (t4) when the electronic device (101) is completely transformed into a fully unfolded state (e.g., FIG. 8a), the Hall sensor (245) may gradually move away from the second magnet (292), and the intensity of the magnetic field detected by the Hall sensor (245) may gradually decrease. After the time point (t4) when the electronic device (101) is completely transformed into a fully unfolded state (e.g., FIG. 8a), the Hall sensor (245) may only detect the magnetic field by the first magnet (291), and the intensity of the magnetic field detected by the Hall sensor (245) may be a fourth magnetic field value (g4) that is smaller than the third magnetic field value (g3). The fourth magnetic field value (g4) may be substantially the same as the first magnetic field value (g1) (e.g., the first magnetic field value (g1) of FIG. 9a).

[0221] FIG. 10a is a schematic diagram of a state in which a digital pen (300) is not stored in the first housing (210) of an electronic device (101), and a schematic diagram of a state in which a digital pen (300) is stored in the first housing (210) of an electronic device (101).

[0222] Referring to FIG. 10A, when the digital pen (300) is not stored in the first housing (210), the Hall sensor (245) may be directly affected by the magnetic field (M1) of a portion of the first magnet (291) (e.g., an upper portion of the first magnet (291) in FIG. 10A), but may not be directly affected by the magnetic field (M2) of a remaining portion of the first magnet (291) (e.g., a lower portion of the first magnet (291) in FIG. 10A). In this case, the Hall sensor (245) may be affected by the magnetic field only from a portion of the first magnet (291), and the intensity of the magnetic field detected by the Hall sensor (245) may be the fifth magnetic field value.

[0223] Referring to FIG. 10b, when the digital pen (300) is housed in the first housing (210), the Hall sensor (245) can be directly influenced by the magnetic field (M1) of a portion of the first magnet (291) (e.g., the upper portion of the first magnet (291) in FIG. 10b) and can be directly influenced by the magnetic field (M3) of the coil (323) of the digital pen (300). For example, when the digital pen (300) is housed in the first housing (210), the coil (323) can be directly influenced by the magnetic field (M2) of the remaining portion of the first magnet (291) (e.g., the lower portion of the first magnet (291) in FIG. 10b). The coil (323) can be magnetized by the magnetic field (M2) of the first magnet (291) to form a magnetic field (M3) generated from the coil (323). In this case, the magnetic field (M3) generated from the coil (323) can affect the Hall sensor (245). For example, when the digital pen (300) is housed in the first housing (210), the Hall sensor (245) can be configured to detect the magnetic field generated from the coil (323) of the digital pen (300). The Hall sensor (245) can be influenced by the magnetic field from a portion of the first magnet (291) and additionally can be influenced by the magnetic field from the coil (323). The intensity of the magnetic field detected by the Hall sensor (245) can be a sixth magnetic field value that is greater than the fifth magnetic field value.

[0224] According to one embodiment, when the digital pen (300) is stored in the first housing (210) (e.g., FIG. 10b), the intensity value of the magnetic field detected by the hall sensor (245) may be different from the intensity value of the magnetic field detected by the hall sensor (245) when the digital pen (300) is not stored in the first housing (210) (e.g., FIG. 10a).

[0225] FIG. 11a is a graph showing the intensity of a magnetic field detected by a Hall sensor (245) when the state of a digital pen (300) in a first housing (210) of an electronic device (101) is changed from a state in which the digital pen (300) is not stored (e.g., FIG. 10a) to a state in which the digital pen (300) is stored (e.g., FIG. 10b), and FIG. 11b is a graph showing the intensity of a magnetic field detected by a Hall sensor (245) when the state of a digital pen (300) in a first housing (210) of an electronic device (101) is changed from a state in which the digital pen (300) is not stored (e.g., FIG. 10a). The horizontal axis of FIGS. 11a and 11b represents time (t), and the vertical axis represents the intensity (G) of the magnetic field.

[0226] Referring to FIGS. 10A, 10B, and 11A, before the time point (t5) when the digital pen (300) is accommodated in the first housing (210), the Hall sensor (245) may be influenced by a magnetic field only from a portion of the first magnet (291). In this case, the intensity of the magnetic field detected by the Hall sensor (245) may be a fifth magnetic field value (g5). After the time point (t5) when the digital pen (300) is accommodated in the first housing (210), the Hall sensor (245) may be influenced by a magnetic field from a portion of the first magnet (291) and additionally may be influenced by a magnetic field from the coil (323). In this case, the intensity of the magnetic field detected by the Hall sensor (245) may be a sixth magnetic field value (g6) that is greater than the fifth magnetic field value (g5).

[0227] Referring to FIGS. 10A, 10B, and 11B, before the time point (t6) at which the digital pen (300) is detached or separated from the first housing (210), the Hall sensor (245) may be influenced by a magnetic field from a portion of the first magnet (291) and may additionally be influenced by a magnetic field from the coil (323). In this case, the intensity of the magnetic field detected by the Hall sensor (245) may be a seventh magnetic field value (g7). The seventh magnetic field value (g7) may be substantially the same as the sixth magnetic field value (g6). After the time point (t6) at which the digital pen (300) is detached or separated from the first housing (210), the Hall sensor (245) may be influenced only by a magnetic field from a portion of the first magnet (291). In this case, the strength of the magnetic field detected by the Hall sensor (245) may be an eighth magnetic field value (g8) that is smaller than the fourth magnetic field value (g7). The eighth magnetic field value (g8) may be substantially equal to the fifth magnetic field value (g5).

[0234] FIG. 15 is a flowchart for determining a state change of an electronic device according to one embodiment of the present disclosure.

[0235] The embodiments of FIGS. 12 to 15 may be combined with the embodiments of FIGS. 1 to 11b.

[0236] To explain the embodiments of FIGS. 12 to 15, reference may be made to the configurations of FIGS. 7, 8a, 8b, 10a, and 10b.

[0237] Hereinafter, for the convenience of explanation of FIGS. 12 to 15, a state in which the digital pen (300) is not stored in the unfolded state of the electronic device (101) may be defined and referred to as a first state of the electronic device (101), a state in which the digital pen (300) is stored in the unfolded state of the electronic device (101) may be defined and referred to as a second state of the electronic device (101), a state in which the digital pen (300) is stored in the folded state of the electronic device (101) may be defined and referred to as a third state of the electronic device (101), and a state in which the digital pen (300) is not stored in the folded state of the electronic device (101) may be defined and referred to as a fourth state of the electronic device (101).

[0238] Referring to FIG. 12, in a first state in which the electronic device (101) is unfolded (e.g., FIG. 8a) and the digital pen (300) is not stored in the first housing (210) (e.g., FIG. 10a), the Hall sensor (245) may be influenced by a magnetic field only from a portion of the first magnet (291). In such a case (e.g., before time t11 of FIG. 12), the intensity of the magnetic field detected by the Hall sensor (245) may be a first magnetic field value (g11).

[0239] According to one embodiment, when the digital pen (300) is stored in the first housing (210) (e.g., FIG. 10b), and the electronic device (101) is in a folded state (e.g., FIG. 8b), the intensity value of the magnetic field detected by the hall sensor (245) may be different from the intensity value of the magnetic field detected by the hall sensor (245) when the electronic device (101) is in an unfolded state (e.g., FIG. 8a).

[0240] In a second state in which the electronic device (101) is unfolded (e.g., FIG. 8a) and the digital pen (300) is housed in the first housing (210) (e.g., FIG. 10b), the Hall sensor (245) may be influenced by a magnetic field from a portion of the first magnet (291) and additionally may be influenced by a magnetic field from the coil (323) of the digital pen (300). In this case (e.g., from after the time point t11 ​​to before the time point t12 in FIG. 12), the strength of the magnetic field detected by the Hall sensor (245) may be a second magnetic field value (g12) greater than the first magnetic field value (g11).

[0241] In a third state in which the electronic device (101) is folded (e.g., FIG. 8b) and the digital pen (300) is housed in the first housing (210) (e.g., FIG. 10b), the Hall sensor (245) may be influenced by a magnetic field from the first magnet (291), may be influenced by a magnetic field from the coil (323) of the digital pen (300), and may additionally be influenced by a magnetic field from the second magnet (292). In this case (e.g., from time t12 to time t13 in FIG. 12), the intensity of the magnetic field detected by the Hall sensor (245) may be a fourth magnetic field value (g14) that is greater than the second magnetic field value (g12). The point in time (t12) at which the intensity of the magnetic field detected by the Hall sensor (245) changes from the second magnetic field value (g12) to the fourth magnetic field value (g14) may be the point in time at which the electronic device (101) is folded and the second magnet (292) is detected. The change from the second magnetic field value (g12) to the fourth magnetic field value (g14) may gradually increase as the second magnet (292) gets closer to the Hall sensor (245). In addition, when the electronic device (101) is completely folded, the intensity of the magnetic field detected by the Hall sensor (245) may have a constant value.

[0242] According to one embodiment, when the digital pen (300) is not stored in the first housing (210) (e.g., FIG. 10a) and the electronic device (101) is in a folded state (e.g., FIG. 8b), the intensity value of the magnetic field detected by the hall sensor (245) may be different from the intensity value of the magnetic field detected by the hall sensor (245) when the electronic device (101) is in an unfolded state (e.g., FIG. 8a).

[0243] In a fourth state in which the digital pen (300) is separated from the first housing (210) (e.g., FIG. 10a) while the electronic device (101) is folded (e.g., FIG. 8b), the Hall sensor (245) may be influenced by a magnetic field from the first magnet (291) and additionally may be influenced by a magnetic field from the second magnet (292). In this case (e.g., after time t13 of FIG. 12), the intensity of the magnetic field detected by the Hall sensor (245) may be a third magnetic field value (g13) that is smaller than the fourth magnetic field value (g14).

[0244] The third magnetic field value (g13) in the fourth state may be greater than the first magnetic field value (g11) in the first state because the second magnet (292) affects the Hall sensor (245).

[0245] The third magnetic field value (g13) in the fourth state is illustrated to have a relatively large value compared to the second magnetic field value (g12) in the second state. However, depending on the arrangement of the components of the electronic device (101), the third magnetic field value (g13) may be smaller than the second magnetic field value (g12). For example, if the electronic device (101) is designed such that the influence of the magnetic field from the coil (323) of the digital pen (300) is greater than the influence of the magnetic field from the second magnet (292), the absolute value of the change from the fourth magnetic field value (g14) to the third magnetic field value (g13) may be greater than the absolute value of the change from the second magnetic field value (g12) to the third magnetic field value (g14).

[0246] According to one embodiment, a processor of an electronic device (101) (e.g., processor (120) of FIG. 1) may be configured to recognize a state (e.g., first state to fourth state) of the electronic device (101) based on the strength of a magnetic field detected by a Hall sensor (245). The processor may be configured to control the operation of the electronic device (101) based on the recognized current state of the electronic device (101).

[0247] Hereinafter, with reference to FIGS. 13a to 13d as examples, the sequential change of states from the first state to the fourth state will be described as an example, but it will be apparent to a person of ordinary skill that the present disclosure is not limited thereto.

[0250] FIGS. 13A to 13D are graphs illustrating an example of Example 3 of Tables 1 to 2. FIG. 13A is a graph showing the intensity value of a magnetic field in three directions detected by a Hall sensor (245) in a first state, FIG. 13B is a graph showing the intensity value of a magnetic field in three directions detected by a Hall sensor (245) when changing from a first state to a second state, FIG. 13C is a graph showing the intensity value of a magnetic field in three directions detected by a Hall sensor (245) when changing from a second state to a third state, and FIG. 13D is a graph showing the intensity value of a magnetic field in three directions detected by a Hall sensor (245) when changing from a third state to a fourth state. For example, the time point t11 ​​of FIG. 13b represents the time point when the digital pen (300) is stored in the first housing (210) of the electronic device (101), the time point t12 of FIG. 13c represents the time point when the second magnet (245) is recognized by the hall sensor (245) when the electronic device (101) is folded, and the time point t13 of FIG. 13d represents the time point when the digital pen (300) is removed from the first housing (210) of the electronic device (101). In FIGS. 13a to 13d, the horizontal axis represents time, and the vertical axis represents the strength of the magnetic field. In FIGS. 13a to 13d, L1 represents the strength of the magnetic field in the X-axis direction detected by the Hall sensor (245), L2 represents the strength of the magnetic field in the Z-axis direction detected by the Hall sensor (245), and L3 represents the strength of the magnetic field in the Y-axis direction detected by the Hall sensor (245).

[0251] Table 1 above shows the strength of the magnetic field in the three-axis directions (e.g., the X-axis direction, the Y-axis direction, and the Z-axis direction of FIG. 7) detected by the Hall sensor (245) in four states (e.g., the first to fourth states) of the electronic device (101). Table 2 above shows the change value of the strength of the magnetic field in the three-axis directions detected by the Hall sensor (245) according to the change in the state of the electronic device (101). In Tables 1 and 2, the Gaussian unit indicating the strength of the magnetic field represents a value in which 10 Gauss (10 G) is equal to 1 millitesla (1 mT). For example, in Table 1, 29.1 G, which is the strength value of the magnetic field in the X-axis direction in the first state of Example 3, can be represented as 2.92 (mT), which is the strength value of the magnetic field of L1 of FIG. 13a.

[0252] In the above embodiment 1, the first magnet (291) and the Hall sensor (245) are spaced apart by 3 mm in the width direction of the electronic device (101) (e.g., the X-axis direction of FIG. 7), in the above embodiment 2, the first magnet (291) and the Hall sensor (245) are spaced apart by 5 mm in the width direction of the electronic device (101), and in the above embodiment 3, the first magnet (291) and the Hall sensor (245) are spaced apart by 10 mm in the width direction of the electronic device (101).

[0253] Examples 1 to 3 used an AK099735D Hall sensor from AKM as the Hall sensor (245), and the first magnet (291) and the second magnet (292) used Halbach array magnets.

[0254] Referring to Table 2, the change value of the intensity value of the magnetic field in the three-axis direction detected by the Hall sensor (245) according to each state change of the electronic device (101) is described. For example, the first change value may be a value obtained by subtracting the intensity value of the magnetic field in the first state from the intensity value of the magnetic field in the second state, the second change value may be a value obtained by subtracting the intensity value of the magnetic field in the second state from the intensity value of the magnetic field in the third state, and the third change value may be a value obtained by subtracting the intensity value of the magnetic field in the third state from the intensity value of the magnetic field in the fourth state. For example, the second change value in the Y-axis direction of Example 1 may be -137.4 (G), which is obtained by subtracting -78.3 (G), which is the intensity value of the magnetic field in the Y-axis direction in the second state, from -215.7 (G), which is the intensity value of the magnetic field in the Y-axis direction in the third state of Example 1 of Table 1.

[0255] Referring to Tables 1 and 2, when the Hall sensor (245) and the first magnet (291) are arranged relatively close together (e.g., Example 1), it can be confirmed that the intensity value of the magnetic field detected by the Hall sensor (245) changes significantly according to the change in the state of the electronic device (101) compared to when the Hall sensor (245) and the first magnet (291) are arranged relatively far apart (e.g., Example 2 and Example 3).

[0256] Referring to Tables 1 and 2, it can be confirmed that the strength value of the magnetic field detected by the Hall sensor (245) in the Y-axis direction changes significantly more than in other axis directions.

[0257] According to one embodiment, the memory of the electronic device (101) (e.g., the memory (130) of FIG. 1) may store information about the intensity value of a magnetic field for a first state in which the electronic device (101) is unfolded and the digital pen (300) is not stored, information about the intensity value of a magnetic field for a second state in which the electronic device (101) is unfolded and the digital pen (300) is stored, information about the intensity value of a magnetic field for a third state in which the electronic device (101) is folded and the digital pen (300) is stored, and information about the intensity value of a magnetic field for a fourth state in which the electronic device (101) is folded and the digital pen (300) is not stored. A processor (e.g., processor (120) of FIG. 1) may be set to determine the current state of the electronic device (101) by comparing the current strength value of the magnetic field detected from the Hall sensor with information stored in the memory (e.g., memory (130) of FIG. 1).

[0258] According to one embodiment, the memory of the electronic device (101) (e.g., the memory (130) of FIG. 1) may store at least one instruction. The at least one instruction, when executed by the electronic device and / or the processor, may cause the electronic device to perform at least one operation. The at least one operation may be defined as an operation performed by the electronic device and / or the processor, but is not limited thereto.

[0259] According to one embodiment, the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may be configured to recognize a current state (e.g., a first state to a fourth state) of the electronic device (101) according to a change in the intensity value of the magnetic field in the Y-axis direction detected by the Hall sensor (245). For example, the processor may be configured to recognize that the current state of the electronic device (101) is any one of the first state to the fourth state when the intensity value of the magnetic field in the Y-axis direction detected by the Hall sensor (245) matches a value that is pre-input, stored, or set in a memory (e.g., the memory (130) of FIG. 1), or falls within a specified range from the value set in the memory.

[0260] However, it is exemplary to detect the current state of the electronic device (101) according to the strength value of the magnetic field in the Y-axis direction detected by the Hall sensor (245). For example, depending on the design position of the first magnet (291) and the Hall sensor (245) of the electronic device (101) or the positions of other components, the change value of the magnetic field detected by the Hall sensor (245) may have a larger value in the X-axis direction or the Z-axis direction than in the other directions, so the change in the magnetic field of the Hall sensor (245) that the processor is set to determine may be a change in the X-axis direction or a change in the Z-axis direction. In addition, in an exemplary embodiment, the processor may be set to recognize the current state of the electronic device (101) through a change in the magnetic field in one axis direction, or through a change in the magnetic field in two or more axis directions.

[0261] Referring to FIG. 14, a method for a processor of an electronic device (101) (e.g., processor (120) of FIG. 1) to recognize the current state of the electronic device (101) is described.

[0262] The embodiment of FIG. 14 is illustrated in the same manner as the embodiment of FIG. 12 in terms of horizontal axis, vertical axis, magnetic field values ​​(g11, g12, g13, g14) and time points (t11, t12, t13), but as previously described, the direction of change in the intensity values ​​of the magnetic field may vary, as described with reference to FIGS. 13a to 13d and Tables 1 to 2 as examples.

[0263] FIG. 14 illustrates an example in which, when the state of the electronic device (101) changes from the first state to the third state, the intensity value of the magnetic field in a specific direction detected by the Hall sensor (245) increases, and when the state of the electronic device (101) changes from the third state to the fourth state, the intensity value of the magnetic field in a specific direction detected by the Hall sensor (245) decreases, but the present disclosure is not limited thereto.

[0264] According to one embodiment, a plurality of threshold values ​​may be stored in a memory of the electronic device (101) (e.g., memory (130) of FIG. 1). For example, a first threshold value (THD1), a second threshold value (THD2), and a third threshold value (THD3) may be stored in the memory (130) of the electronic device (101).

[0265] The first threshold value (THD1) may be greater than the first magnetic field value (g11) and less than the second magnetic field value (g12). The second threshold value (THD2) may be greater than the second magnetic field value (g12) and less than the fourth magnetic field value (g14). The second threshold value (THD2) may be less than the third magnetic field value (g13). The third threshold value may be less than the fourth magnetic field value (g14) and greater than the second magnetic field value (g12). The third threshold value (TH3) may be greater than the third magnetic field value (g13).

[0266] According to one embodiment, a processor of the electronic device (101) (e.g., processor (120) of FIG. 1) may be set to determine the current state of the electronic device (101) by comparing a current strength value of a magnetic field detected from a Hall sensor (245) with a plurality of threshold values ​​stored in the memory (e.g., memory (130) of FIG. 1).

[0267] According to one embodiment, the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may be set to determine that the current state of the electronic device (101) is the first state when the intensity value of the magnetic field detected by the Hall sensor (245) is smaller than a first threshold value (THD1) pre-stored in a memory (e.g., the memory (130) of FIG. 1).

[0268] According to one embodiment, the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may be set to determine that the current state of the electronic device (101) is the second state when the intensity value of the magnetic field detected by the Hall sensor (245) is greater than a first threshold value (THD1) pre-stored in a memory (e.g., the memory (130) of FIG. 1) and less than a second threshold value (THD2).

[0269] According to one embodiment, the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may be set to determine that the current state of the electronic device (101) is the third state when the strength value of the magnetic field detected by the Hall sensor (245) is greater than a third threshold value (THD1) pre-stored in a memory (e.g., the memory (130) of FIG. 1).

[0270] According to one embodiment, the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may be set to determine that the current state of the electronic device (101) is the fourth state when the intensity value of the magnetic field detected by the Hall sensor (245) is greater than the second threshold value (THD2) pre-stored in the memory (e.g., the memory (130) of FIG. 1) and less than the third threshold value (TH3).

[0271] FIG. 15 is a flowchart for determining a state change of an electronic device according to one embodiment of the present disclosure.

[0272] According to one embodiment, the memory of the electronic device (101) (e.g., the memory (130) of FIG. 1) may store magnetic values ​​for each state (e.g., the first state to the fourth state) of the electronic device (101) (1001). For example, the intensity value of the magnetic field detected by the Hall sensor (245) in each state of the electronic device (101) may be stored, set, or input in advance in the memory. For example, the range of the intensity values ​​of the magnetic field detected in each of the first state to the fourth state may be stored in the memory of the electronic device (101).

[0273] According to one embodiment, the memory of the electronic device (101) may store an open / close recognition threshold value and a digital pen detection value (1003). For example, the memory may pre-store a change value of a magnetic value (e.g., a change amount of a magnetic field strength value) when the electronic device (101) changes from an unfolded state to a folded state, or vice versa. In addition, the memory may pre-store a change value of a magnetic value (e.g., a change amount of a magnetic field strength value) when the digital pen (300) changes from a non-stored state to a stored state in the first housing (210) of the electronic device (101), or vice versa. The processor may be configured to determine the current state of the electronic device (101) by comparing the current intensity value of the magnetic field detected by the Hall sensor (245) with the open / close recognition value and the digital pen detection value stored in the memory.

[0274] For example, the above open / close recognition threshold value may be set to 136.2G, which is the absolute value of -136.2G, which is the difference between the intensity value of the magnetic field in the first state in the Y-axis direction (-91.9G) and the intensity value of the magnetic field in the fourth state (-228.1G) in the Y-axis direction of Embodiment 1. In addition, the above open / close recognition threshold value may be set to the absolute value of the difference between the intensity value of the magnetic field in the second state in the Y-axis direction of Embodiment 1 and the intensity value of the magnetic field in the third state. However, the present disclosure is not limited thereto, and may be set to various values ​​depending on design changes.

[0275] For example, the digital pen detection value may be set to 13.6G, which is the absolute value of 13.6G, which is the difference between the intensity value of the magnetic field in the first state (-91.9G) in the Y-axis direction of Example 1 and the intensity value of the magnetic field in the second state (-78.3G), as described with Table 1 as an example. In addition, the open / close recognition threshold value may be set to the absolute value of the difference between the intensity value of the magnetic field in the third state and the intensity value of the magnetic field in the fourth state in the Y-axis direction of Example 1. However, the digital pen detection value is not limited thereto, and may have various values ​​depending on design changes.

[0276] As an example, a case in which a digital pen detection value is lower than an open / close recognition threshold value is described, but the present disclosure is not limited thereto. The digital pen detection value may be defined and / or referred to as a digital pen threshold value, and the open / close recognition threshold value may be defined and / or referred to as an open / close recognition detection value.

[0277] According to one embodiment, the processor of the electronic device (101) may be configured to store the current magnetic sensing value detected by the Hall sensor (245) as a base value in the memory (1005). For example, the current magnetic sensing value may be a magnetic field intensity value detected by the Hall sensor (245). The processor of the electronic device (101) may be configured to determine which range of the pre-stored first to fourth states the base value belongs to. The processor of the electronic device (101) may determine the range to which the base value belongs and, accordingly, recognize the current state of the electronic device (101).

[0278] According to one embodiment, the processor of the electronic device (101) may be configured to check the current magnetic sensing value detected by the Hall sensor (245) at a specified time interval. For example, the specified time interval may be 50 ms, but is not limited thereto.

[0279] According to one embodiment, the processor of the electronic device (101) may be configured to determine whether the current magnetic sensing value detected by the Hall sensor (245) has changed from the magnetic sensing value of the previous time period (or, previous time period) (1007). For example, if the current magnetic sensing value detected by the Hall sensor (245) has not changed from the magnetic sensing value of the previous time period, the processor may store the current magnetic sensing value in memory (1005).

[0280] If the current magnetic sensing value detected by the Hall sensor (245) has changed from the magnetic sensing value of the previous time period, the processor may be set to determine whether the change in the magnetic sensing value is greater than the digital pen detection value (1009). For example, the processor may be set to determine whether the change in the magnetic sensing value is greater than or equal to the digital pen detection value. For example, if the change in the magnetic sensing value is less than the digital pen detection value, or if the change in the magnetic sensing value is less than the digital pen detection value, the processor may determine that there is no change in the state of the electronic device (1011). The change in the magnetic sensing value may be defined and / or referred to as an absolute value of the difference between the magnetic sensing value of the previous time period and the magnetic sensing value of the current time period.

[0281] If the change value of the magnetic sensing value is greater than the digital pen detection value, or if the change value of the magnetic sensing value is greater than or equal to the digital pen detection value, the processor may be configured to determine whether the change value of the magnetic sensing value is less than an open / closed recognition threshold value (1013). For example, if the change value of the magnetic sensing value is less than the open / closed recognition threshold value, or if the change value of the magnetic sensing value is less than or equal to the open / closed recognition threshold value, the processor may be configured to determine that a storage change event of the digital pen (300) of the electronic device (101) has occurred (1015). For example, if the change value of the magnetic sensing value is greater than the digital pen detection value and less than the open / closed recognition threshold value (or if the change value of the magnetic sensing value is greater than or equal to the digital pen detection value and less than the open / closed recognition threshold value), the processor may determine that the digital pen (300) has changed from an unstored state to a stored state, or that the digital pen (300) has changed from a stored state to an unstored state. For example, if a change event of storing a digital pen (300) occurs when the electronic device (101) was previously stored with the digital pen (300), the processor can determine that an event of removing the digital pen (300) has occurred. In addition, if a change event of storing a digital pen (300) occurs when the electronic device (101) was previously stored with the digital pen (300) not, the processor can determine that an event of storing the digital pen (300) has occurred.

[0282] For example, if the change value of the magnetic sensing value is greater than the open / close recognition threshold value, or if the change value of the magnetic sensing value is equal to or greater than the open / close recognition threshold value, the processor may be set to determine that an open / close change event of the electronic device (101) has occurred (1017). For example, if the change value of the magnetic sensing value is greater than the open / close recognition threshold value, or if the change value of the magnetic sensing value is equal to or greater than the open / close recognition threshold value, the processor may determine that the electronic device (101) has changed from a folded state to an unfolded state, or that the electronic device (101) has changed from an unfolded state to a folded state. For example, if the electronic device (101) was just folded and an open / close change event occurs, the processor may determine that an event of unfolding the electronic device (101) has occurred. Additionally, when an open / close change event occurs while the electronic device (101) is in an unfolded state, the processor can determine that an event of folding the electronic device (101) has occurred.

[0283] According to one embodiment, the processor may be configured to determine the current state of the electronic device (101) based on processes 1011, 1015, and 1017 (1019). After determining the current state of the electronic device (101), the processor may be configured to sequentially determine the current state of the electronic device (101) again starting from process 1005.

[0284] A foldable electronic device may include a foldable flexible display arranged over the entire area of ​​a housing structure and may include multiple housing structures to support the display. Accordingly, the foldable electronic device may have various components arranged and / or mounted on each of the multiple housing structures. As the functions of the foldable electronic device diversify, the number of components arranged and / or mounted within the foldable electronic device is increasing. However, since the overall size or internal space of the foldable electronic device is limited, it may be difficult to secure sufficient space for the arrangement and / or mounting of various components.

[0285] Additionally, a stylus pen for implementing a user's handwriting input may be configured to be stored inside the foldable electronic device. In such a case, the foldable electronic device may have separate components for detecting the handwriting input of the stylus pen and for detecting the stylus pen's storage status, making it difficult to secure space for arranging multiple components for the stylus pen.

[0286] Additionally, the foldable electronic device may be provided with components for detecting the folding state of the foldable electronic device.

[0287] In this way, since the components for detecting whether the stylus pen is stored and the components for detecting the folding state of the foldable electronic device are provided separately, it may be difficult to secure installation space for each component in the limited internal space of the foldable electronic device.

[0288] According to one embodiment of the present disclosure, an electronic device may be provided that provides a structure capable of detecting a folding state of an electronic device and a storage state of a digital pen through one hall sensor.

[0289] However, 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.

[0290] According to one embodiment of the present disclosure, a hall sensor can provide information for recognizing a folding state of an electronic device and information for recognizing a storage state of a digital pen.

[0291] According to one embodiment of the present disclosure, since both the folding state of the electronic device and the stowed state of the digital pen can be detected through a single hall sensor, no separate additional component is required for detection of the digital pen, thereby reducing costs.
