[0021] Figure 1 illustrates examples of an electronic device, an accessory for the electronic device, and a wireless charging device.

[0022] The electronic device (101) of FIG. 1 may be an example of the electronic device (1001) of FIG. 10. For example, the electronic device (101) may include at least a part of the electronic device (1001) or correspond to at least a part of it. For example, the electronic device (101) may be implemented in various form factors. For example, the electronic device (101) may include an electronic device (e.g., a smartphone) that includes the display of the bar type, as well as an electronic device that includes the display of the flexible display. For example, the flexible display may include an electronic device that includes a foldable display, an electronic device that includes a multi-foldable display, or an electronic device that includes a rollable display. Also, for example, the electronic device (101) may include a tablet PC (personal computer). Also, for example, the electronic device (101) may be implemented as a wearable device. For example, the wearable device may include a head-mounted display (HMD) or a watch-shaped device. However, the present disclosure is not limited thereto.

[0023] For example, a portion of the electronic device (101) seen from direction A may be referred to as the front side (or first side) of the electronic device (101). In the above example, the portion seen from direction A is described as the front side, but the present disclosure is not limited thereto. For example, at least some of the components included in the electronic device (101) that are positioned in direction A may be included (or positioned, disposed) in the front side of the electronic device (101). For example, a portion of the electronic device (101) seen from direction B may be referred to as the rear side (or second side) of the electronic device (101). The rear side may be a side of the electronic device (101) opposite to the front side. In the above example, the portion seen from direction B is described as the rear side, but the present disclosure is not limited thereto. For example, at least some of the components included in the electronic device (101) that are positioned in direction B may be included (or positioned, placed) on the rear side of the electronic device (101).

[0024] For example, it may include a housing (110) that defines at least a portion of the exterior of the electronic device (101). For example, the housing (110) may define a lateral side between the front side and the rear side of the electronic device (101). However, the present disclosure is not limited thereto. For example, the housing (110) may further define at least a portion of the front side and / or at least a portion of the rear side. For example, the housing (110) may include a rear cover (120) positioned toward the rear side. For example, the rear cover (120) may define the rear side of the electronic device (101). For example, the rear cover (120) may be connected to (or contacted, coupled to) the housing (110). Although not shown in FIG. 1, the electronic device (101) may include a display that defines the front side of the electronic device (101). For example, the display may be connected to (or contacted, coupled to) the housing (110). The display may be an example of the display module (1060) of FIG. 10. For example, the display may include at least a part of the display module (1060) or correspond to at least a part of the display module (1060).

[0025] For example, the electronic device (101) may include at least one coil (140) disposed within the housing (110). For example, at least one coil (140) may be used for wireless charging. Additionally, for example, at least one coil (140) may be used for wireless communication. By example, without limitation, the wireless communication may include near field communication (NFC). For example, at least one coil (140) may be located in front of (or below) the rear cover (120) defining the rear side of the electronic device (101) within the housing (110). Being located in front of (or below) the rear cover (120) may indicate being located in an area moved from the rear cover (120) toward (or toward the A direction) the display defining the front side of the electronic device (101). In other words, what is positioned in front of (or below) the rear cover (120) may indicate that it is positioned between the rear cover (120) and the display defining the front side of the electronic device (101).

[0026] For example, the electronic device (101) may include at least one sensor. For example, the at least one sensor may include a Hall sensor (150). For example, the Hall sensor (150) may be configured to detect a magnetic field with respect to the rear side of the electronic device (101) (or with respect to the rear side direction). By example, without limitation, the magnetic field may be generated from outside the electronic device (101). The Hall sensor (150) may utilize the Hall effect to detect changes in the magnetic field. Specific details regarding the Hall effect are illustrated and described below with reference to FIG. 3. The Hall sensor (150) may be referred to as a Hall effect sensor, a magnetic field sensing sensor, or a magnetic force sensing sensor.

[0027] For example, the Hall sensor (150) may be placed within the housing (110). As a non-limiting example, the Hall sensor (150) may be placed in front of (or below) at least one coil (140). Being placed in front of (or below) at least one coil (140) may indicate being located in an area moved from at least one coil (140) toward (or in direction A) the display defining the front side of the electronic device (101). In other words, being placed in front of (or below) at least one coil (140) may indicate being located between at least one coil (140) and the display defining the front side of the electronic device (101). Conversely, at least one coil (140) may be placed behind (or above) the Hall sensor (150). At least one coil (140) being positioned behind (or on) the Hall sensor (150) may indicate that it is located in an area moved from the Hall sensor (150) toward the rear cover defining the rear side of the electronic device (101) (or toward the B direction).

[0028] For example, the electronic device (101) may be combined with an accessory (180) of the electronic device (101). For example, the accessory (180) may be mounted on the electronic device (101). The accessory (180) may be referred to as the case of the electronic device (101). For example, the accessory (180) may include a magnet (185). For example, the magnet (185) of the accessory (180) may be formed of a magnetic material. By example, without limitation, the magnet (185) may be referred to as a permanent magnet or a hard magnetic member. For example, the magnet (185) may correspond to at least one coil (140) of the electronic device (101). The fact that the magnet (185) corresponds to at least one coil (140) may include the magnet (185) of the accessory (180) being aligned with at least one coil (140) when the accessory (180) is mounted on the electronic device (101). In other words, when the accessory (180) is mounted on the electronic device (101), the position of the magnet (185) of the accessory (180) may be located in an area of ​​the rear cover (120) of the electronic device (101) that overlaps (or at least partially overlaps) with the area where at least one coil (140) is located. This may be so that when wireless charging is performed using at least one coil (140), the electronic device (101) wearing the case accessory (180) can also perform wireless charging more efficiently. As an example without limitation, the shape of the magnet (185) may have a circular band shape. The magnet (185) formed as a circular band can be more easily attached to at least one coil (140).

[0029] The use of magnetic absorption (or attachment) during wireless charging can be defined as a magnetic power profile (MPP) (or MPP standard). By example, without limitation, wireless charging of an electronic device (101) can be performed by a wireless charging device (190). For example, the wireless charging device (190) can provide power (or voltage, current) provided from an external source to the electronic device (101). For example, the wireless charging device (190) may be referred to as a wireless charging interface, a wireless charger, or a charging device.

[0030] For example, an electronic device (101) may be in contact with (or attached to) a wireless charging device (190). For example, the wireless charging device (190) may include a magnet (195) to be in contact with (or attached to) the electronic device (101). For example, the magnet (195) of the wireless charging device (190) may be formed of a magnetic material. By example, without limitation, the magnet (195) may be referred to as a permanent magnet or a hard magnetic member. For example, the magnet (195) may correspond to at least one coil (140) of the electronic device (101). That the magnet (195) corresponds to at least one coil (140) may include the magnet (195) of the wireless charging device (190) being aligned with at least one coil (140) when the wireless charging device (190) is mounted on the electronic device (101). In other words, when the electronic device (101) comes into contact with the wireless charging device (190), the position of the magnet (195) of the wireless charging device (190) may be located above an area that overlaps (or at least partially overlaps) with the area where at least one coil (140) is located in the area of ​​the rear cover (120) of the electronic device (101). This may be to perform wireless charging of the electronic device (101) more efficiently when performing wireless charging using at least one coil (140). As an example without limitation, the shape of the magnet (195) may be circular. A magnet (195) formed in a circular shape can be more easily attached to at least one coil (140).

[0031] A Hall sensor (150) of an electronic device (101) may be configured to detect a magnetic field caused by a magnet (185) of an accessory (180) when the accessory (180) is mounted with the electronic device (101). For example, the Hall sensor (150) may detect a change in the magnetic field caused by the magnet (185), which changes as the accessory (180) is moved adjacent to the electronic device (101) to be mounted with the electronic device (101). Additionally, a Hall sensor (150) of an electronic device (101) may be configured to detect a magnetic field caused by a magnet (195) of a wireless charging device (190) when the electronic device (101) is positioned adjacent to a wireless charging device (190) for charging the battery of the electronic device (101). For example, the Hall sensor (150) can detect changes in the magnetic field caused by the magnet (195), which change as the electronic device (101) moves adjacent to the wireless charging device (190) to charge the battery of the electronic device (101) through the wireless charging device (190). By example, without limitation, detecting the magnetic field (or detecting changes in the magnetic field) may include a comparison between an electrical characteristic (e.g., voltage) measured through the Hall sensor (150) and a reference value. For example, the Hall sensor (150) can detect a magnetic field caused by an external device (e.g., an accessory (180) or a wireless charging device (190)) by comparing the magnitude of the voltage (or Hall voltage) caused by changes in the magnetic field with a reference voltage. Specific details regarding this are illustrated and described below with reference to FIG. 3.

[0032] As described above, the Hall sensor (150) may be included in the electronic device (101). An exemplary location of the Hall sensor (150) included in the electronic device (101) is illustrated and described with reference to FIG. 2a below.

[0033] FIG. 2a shows an exploded perspective view of an exemplary electronic device.

[0034] FIG. 2a illustrates an example of an exploded perspective view of the electronic device (101) of FIG. 1. For example, the electronic device (101) of FIG. 2a may be an example of the electronic device (101) of FIG. 1 exploded along direction A (or direction B).

[0035] Referring to FIG. 2a, the electronic device (101) may include a housing (110), a rear cover (120), a display (230), a printed circuit board (PCB) (220), another housing (240), and a wireless charging assembly (250). The components included in the electronic device (101) shown in FIG. 2a and the arrangement (or connection) between said components of the electronic device (101) are merely examples for convenience of explanation and the present disclosure is not limited thereto.

[0036] For example, the housing (110) may define at least a portion of the exterior of the electronic device (101). The housing (110) may be located between the rear cover (120) and the display (230). For example, the housing (110) may define at least a portion of the lateral side of the electronic device (101) between the display (230), which defines at least a portion of the front side of the electronic device (101), and the rear cover (120), which defines at least a portion of the rear side of the electronic device (101). However, the present disclosure is not limited thereto. For example, the housing (110) may further define at least another portion of the front side and / or at least another portion of the rear side. In other words, the front side of the electronic device (101) may be defined by the housing (110) and the display (230), and the rear side of the electronic device (101) may be defined by the housing (110) and the rear cover (120). For example, the housing (110) may be connected to (or contacted, coupled to) the display (230) and the rear cover (120). When viewing the electronic device (101) from outside the electronic device (101), the portion of the housing (110) defining the lateral side of the electronic device (101) may be referred to as a frame. For example, the housing (110) may include a bracket (210). For example, the bracket (210) may be a part of the housing (110) on which at least some of the components of the electronic device (101) are placed. For example, the bracket (210) may extend from the frame of the housing (110) into the electronic device (101). As an example without limitation, the bracket (210) may be connected (or coupled) to the frame of the housing (110).

[0037] In the present disclosure, the housing (110) may be referred to as a front housing as it is positioned relatively in front of another housing (240). Alternatively, the housing (110) may be referred to as a main housing as it includes a bracket (210) on which a PCB (220) is placed, as described below.

[0038] For example, the display (230) may be used to provide visual information (or images). As an example without limitation, the display (230) may be positioned in front of (or below) the housing (110). Positioning the display (230) in front of (or below) the housing (110) may indicate that the display (230) is positioned in an area moved toward the direction A of FIG. 1 relative to the housing (110) to define the front side of the electronic device (101). In other words, the display (230) may be positioned at the very front of the components of the electronic device (101).

[0039] For example, the PCB (220) may be placed inside the housing (110). For example, the PCB (220) may be placed on (or on) the bracket (210) of the housing (110). For example, the PCB (220) may be a part on which components of the electronic device (101) are mounted (or placed, included). By example, without limitation, at least one processor of the electronic device (101) (e.g., processor (1020) of FIG. 10), memory (e.g., memory (1030) of FIG. 10), or battery (e.g., battery (1089) and / or power management module (1088) of FIG. 10) may be placed on (or included, mounted) the PCB (220). By example, without limitation, the at least one processor may include an application processor (AP), a power management integrated circuitry (PMIC), or a communication circuit. Additionally, for example, the PCB (220) may include a Hall sensor (150). As an example without limitation, the Hall sensor (150) may be mounted on one side of the PCB (220). In the present disclosure, the PCB (220) may be implemented as a single PCB or as a plurality of PCBs. If implemented as a plurality of PCBs, the PCB (220) may be referred to as a printed board assembly (PBA). For example, the PBA may include the PCB (220) and other PCBs.

[0040] For example, another housing (240) may be located behind (or on top of) the PCB (220). For example, the other housing (240) may be located behind (or on top of) the PCB (220) and may be at least partially connected (or in contact with, coupled to) the housing (110) (or bracket (210)). For example, components of the electronic device (101) may be coupled to the other housing (240). As an example, but not limited to, a wireless charging assembly (250) may be placed on one side of the other housing (240). For example, the other housing (240) may be referred to as a rear housing as it is located relatively close to the rear cover (120) compared to the housing (110). Or, for example, the other housing (240) may be referred to as a sub-housing in that it is connected to the housing (110). In FIG. 2a, an electronic device (101) including another housing (240) is shown, but the present disclosure is not limited thereto. For example, the other housing (240) may not be included in the electronic device (101).

[0041] For example, the wireless charging assembly (250) may include components for wireless charging of the electronic device (101). By example, without limitation, the components for wireless charging may include at least one coil (140) or at least one circuit for controlling wireless charging (hereinafter, wireless charging circuit). For example, the wireless charging assembly (250) may be electrically connected to at least one processor (e.g., PMIC or communication circuit) placed on the PCB (220). For example, at least one coil (140) of the wireless charging assembly (250) may be used to receive power from a wireless charging device outside the electronic device (101) (e.g., wireless charging device (190) of FIG. 1). Or, for example, at least one coil (140) of the wireless charging assembly (250) may be used for wireless communication (e.g., NFC). For example, the wireless charging assembly (250) may be located behind (or on top of) the PCB (220). Alternatively, for example, the wireless charging assembly (250) may be located behind (or on top of) another housing (240).

[0042] For example, the rear cover (120) may be used to cover the rear side of the electronic device (101). As a non-limiting example, the rear cover (120) may be positioned behind (or on top of) the housing (110). For example, the rear cover (120) may be positioned behind (or on top of) the wireless charging assembly (250). Positioning the rear cover (120) behind (or on top of) the housing (110) may indicate that the rear cover (120) is positioned in an area moved toward the direction B of FIG. 1 relative to the housing (110) to define the rear side of the electronic device (101). In other words, the rear cover (120) may be positioned at the rearmost of the components of the electronic device (101). In one example, at least one camera of the electronic device (101) may be visually exposed through a portion of the rear cover (120). For example, the at least one camera may be electrically connected to the at least one processor (or control circuit for controlling the at least one camera) of the PCB (220). In FIG. 2a, the rear cover (120) is illustrated as not including an additional display, but the present disclosure is not limited thereto. For example, if the electronic device (101) includes a flexible display (or a foldable display), the display (or sub-display) may be visually exposed through at least a portion of the rear cover (120).

[0043] Although not illustrated in FIG. 2a, the electronic device (101) may include a magnet. For example, the electronic device (101) may include the magnet located behind (or above) a wireless charging assembly (250) that includes at least one coil (140) and in front (or below) a rear cover (120). Or, for example, the electronic device (101) may include the magnet located in front (or below) a wireless charging assembly (250) that includes at least one coil (140) and in front (or above) another housing (240). For example, the magnet may be used to attach (or adsorb) to a magnet (e.g., the magnet (185) or magnet (195) of FIG. 1) of an external object (e.g., the accessory (180) or wireless charging device (190) of FIG. 1).

[0044] FIG. 2b shows an exploded perspective view of an accessory of an exemplary electronic device.

[0045] FIG. 2b illustrates an example of an exploded perspective view of an accessory (180) of the electronic device (101) of FIG. 1. For example, the accessory (180) of FIG. 2b may be an example of the accessory (180) of FIG. 1 being disassembled.

[0046] Referring to FIG. 2b, the accessory (180) may include a housing (260), a magnet (185), and a shielding member (270). The components included in the accessory (180) shown in FIG. 2b are merely examples for convenience of explanation and are not limited thereto.

[0047] For example, the housing (260) may define the appearance of the accessory (180). For example, the housing (260) may be used to cover at least a portion of the appearance of the electronic device (101) when the accessory (180) is mounted on the electronic device (101). For example, the at least portion of the appearance of the electronic device (101) covered by the housing (260) may include at least a portion of the lateral side of the electronic device (101) and at least a portion of the rear side of the electronic device (101).

[0048] For example, the magnet (185) may be contained within the housing (260). For example, the magnet (185) may be inserted (or embedded) into a portion (265) of the housing (260). For example, the portion (265) of the housing (260) may represent a space into which the magnet (185) and the shielding member (270) can be inserted. As a non-limiting example, the magnet (185) may have a continuous circular band shape. In one example, the outermost portion (or circumference) (185-1) of the magnet (185) may have a first polarity (e.g., N pole), and the innermost portion (or circumference) (185-2) of the magnet (185) may have a second polarity (e.g., S pole). However, the present disclosure is not limited thereto. The outermost part (185-1) of the magnet (185) may have the second polarity, and the innermost part (185-2) of the magnet (185) may have the first polarity. For example, the magnet (185) may cause (or form) a magnetic field directed from the first polarity toward the second polarity.

[0049] For example, a shielding member (270) may be used to shield the magnetic field caused (or formed) by the magnet (185). For example, when the accessory (180) is mounted on the electronic device (101), the shielding member (270) may at least partially shield (or suppress, reduce) the magnetic field caused by the magnet (185) to reduce the effect (e.g., noise) on components inside the electronic device (101). For example, the shielding member (270) may at least partially shield the magnetic field directed toward the electronic device (101) by causing the magnetic field caused by the magnet (185) to form a closed-loop. For example, the shielding member (270) may be referred to as a magnetic shield or a case yoke.

[0050] For example, the shielding member (270) may have a circular band shape that is at least partially broken. For example, in area (285), one end (271) of the shielding member (270) may be spaced apart from another end (272) of the shielding member (270). For example, the other end (272) of the shielding member (270) may represent an end opposite to the one end (271) of the shielding member (270). For example, the broken area (285) of the shielding member (270) may correspond to the area (280) of the magnet (185). The fact that the area (285) of the shielding member (270) is cut off corresponds to the area (280) of the magnet (185) indicates that when the magnet (185) of the accessory (180) and the shielding member (270) are combined within the accessory (180), the area (280) of the magnet (185) is aligned with the area (285) of the shielding member (270). For example, in the example of FIG. 2b where the accessory (180) is viewed from direction D, the shielding member (270) may come into contact with (or be combined with, connected to) the magnet (185). At this time, the area (280) of the magnet (185) may be visually exposed from direction D through the area (285) of the shielding member (270).

[0051] For example, the electronic device (101) can detect, through a Hall sensor (150), a magnetic field caused (or formed) through the region (280) of a magnet (185) when an accessory (180) is mounted on the electronic device (101). Specific details regarding how the electronic device (101) detects the magnetic field through the Hall sensor (150) may be referenced below in FIG. 3.

[0052] Figure 3 illustrates an example of the Hall effect.

[0053] FIG. 3 illustrates an example (300) of a method in which the Hall sensor (150) of FIG. 1 detects a magnetic field using the Hall effect. In the example (300) of FIG. 3, the magnet (320) may be an example of the magnet (185) of the accessory (180) of FIG. 1 or the magnet (195) of the wireless charging device (190).

[0054] Referring to example (300), the Hall sensor (150) may include a power source (301) and an element (302). For example, the power source (301) may be a source for providing current (310) to the element (302). By example, without limitation, the power source (301) may be referred to as a DC (direct current) source. By example, without limitation, the element (302) may be a semiconductor. For example, the element (302) may be a p-type semiconductor. However, the present disclosure is not limited thereto. For example, the element (302) may be a conductor. For example, the current (310) provided to the element (302) by the power source (301) may have a specific value (or a constant).

[0055] If a magnetic field (325) is not formed by the magnet (320), a force (or magnetic force) caused by the magnet (320) (or the magnetic field caused by the magnet (320)) may not be generated inside the element (302). The fact that a magnetic field (325) is not formed by the magnet (320) may indicate that the magnet (320) is not positioned adjacent to the Hall sensor (150) (or the element (302)) or that the position of the magnet (320) does not change in the area adjacent to the Hall sensor (150) (or the element (302)). Accordingly, a current (330) according to the current (310) may be formed inside the element (302). The current (330) may indicate the direction of movement of charge according to the current (310) passing through the element (302).

[0056] When a magnetic field (325) is formed by a magnet (320), a force (or magnetic force) caused by the magnet (320) (or the magnetic field caused by the magnet (320)) may be generated inside the element (302). For example, as electrons inside the element (302) move due to the magnetic field (325), a force may be generated in a direction perpendicular to the direction in which the current (330) flows. The formation of a magnetic field (325) by a magnet (320) may indicate that the magnet (320) is positioned adjacent to the Hall sensor (150) (or the element (302)) or that the position of the magnet (320) changes in an area adjacent to the Hall sensor (150) (or the element (302)). Due to the force caused by the magnetic field (325), a current (340) according to the current (310) may be generated inside the element (302). For example, due to the force caused by the magnetic field (325), positive charges may accumulate at the first end (351) of the element (302) in a direction perpendicular to the direction in which the current (330) flows, and negative charges may accumulate at the other second end (352) of the element (302). Accordingly, a voltage (or potential difference) may be formed inside the element (302) in a direction perpendicular to the direction in which the current (330) flows. The formation of the voltage by the magnetic field (325) may be referred to as the Hall effect. In other words, by the magnetic field (325), the current inside the element (302) according to the current (310) may be changed from the current (330) to the current (340).

[0057] The Hall sensor (150) can measure (or detect, identify) the voltage between the first terminal (351) and the second terminal (352) of the element (302). For example, the Hall sensor (150) may be configured to detect a magnetic field (325) as it measures the voltage. As an example, but not limited to, the electronic device (101) (or a control circuit that controls the Hall sensor (150), the Hall sensor (150)) may compare the measured voltage formed by the magnetic field (325) with at least one reference voltage. For example, the electronic device (101) may identify the location of a magnet (320) outside the electronic device (101) as it compares the measured voltage with the at least one reference voltage. For example, the electronic device (101) may identify the location of the magnet (320) from the electronic device (101) as a first location when the measured voltage is less than a first reference voltage. For example, if the measured voltage is greater than or equal to the first reference voltage and less than the second reference voltage that exceeds the first reference voltage, the electronic device (101) can identify the position of the magnet (320) from the electronic device (101) as a second position closer than the first position.

[0058] In example (300), the electronic device (101) is described as identifying the position of the magnet (320) based on a comparison between the measured voltage and at least one reference voltage, but the present disclosure is not limited thereto. For example, the electronic device (101) may detect (or recognize, identify) whether the magnet (320) is in contact with the electronic device (101). As a non-limiting example, the electronic device (101) may detect that the accessory (180) is mounted on the electronic device (101) as it detects that the magnet (185) of the accessory (180) is in contact with the electronic device (101). As an example not limited to, the electronic device (101) may display a message indicating that the charging status is abnormal through the display (230) of the electronic device (101) as it detects that the magnet (195) of the wireless charging device (190) (and the magnet (185) of the accessory (180)) has come into contact with the electronic device (101) and then has not come into contact again. Or, as an example not limited to, the electronic device (101) may stop charging the battery of the electronic device (101) as it detects that the magnet (195) of the wireless charging device (190) has come into contact with the electronic device (101) and then has not come into contact again.

[0059] In the above example, the Hall sensor (150) is shown as measuring voltage, but the present disclosure is not limited thereto. For example, the Hall sensor (150) may measure electrical characteristics other than the voltage (e.g., current) caused (or altered) by the magnetic field (325).

[0060] As described above, the Hall sensor (150) can detect the magnetic field (325) by measuring the voltage (or electrical characteristic) according to the force caused by the magnetic field (325). At this time, the change (or amount of change) of the voltage can be determined according to the strength of the magnetic field (325). In other words, the Hall sensor (150) can detect the magnetic field (325) more easily as the strength of the magnetic field (325) affecting the Hall sensor (150) increases. Specific details regarding the method of adjusting the strength of the magnetic field (325) affecting the Hall sensor (150) are illustrated and explained below with reference to FIG. 4.

[0061] Figure 4 illustrates an example of a change in the path of magnetic field lines caused by a magnetic member.

[0062] FIG. 4 illustrates an example (400) of a magnetic field caused by magnets (410, 420) and an example (450) of a magnetic field modified by a magnetic member (460) between magnets (410, 420) from the magnetic field of example (400). In FIG. 4, for convenience of explanation, it is assumed that the magnet (410) has a first polarity (e.g., N pole) and the magnet (420) has a second polarity (e.g., S pole).

[0063] Referring to Example (400), a magnetic field can be formed by a magnet (410) and a magnet (420). For example, the magnetic field formed by the magnet (410) and the magnet (420) can be formed to be directed from the magnet (410) toward the magnet (420). In Example (400), the magnetic field formed by the magnet (410) and the magnet (420) can be represented by magnetic force lines (431, 432, 433, 434). For example, the magnetic force lines (431, 432, 433, 434) can be parallel to each other. As the magnet (410) and the magnet (420) are arranged parallel to each other, the magnetic force lines (431, 432, 433, 434) can have substantially the same strength (or magnitude) as each other. The spacing between the magnetic field lines (431, 432) may be substantially the same as the spacing between the magnetic field lines (433, 434). For example, the spacing between the magnetic field lines (431, 432, 433, 434) may represent the strength of the magnetic field. In other words, the strength of the magnetic field may be substantially the same regardless of location.

[0064] Referring to Example (450), a magnetic field can be formed by a magnet (410) and a magnet (420). Similar to Example (400), the magnetic field formed by the magnet (410) and the magnet (420) can be formed to be directed from the magnet (410) toward the magnet (420). For example, the magnetic field formed by the magnet (410) and the magnet (420) can be represented by magnetic field lines (481, 482, 483, 484). For example, magnetic field line (481) can correspond to magnetic field line (431) of Example (400). For example, magnetic field line (484) can correspond to magnetic field line (434) of Example (400). For example, magnetic force lines (481, 482, 483, 484) may be parallel to each other in an area adjacent to the magnet (410). For example, magnetic force line (481) may be partially parallel to a portion (482a) of magnetic force line (482). For example, magnetic force line (484) may be partially parallel to a portion (483a) of magnetic force line (483). Among the magnetic force lines (481, 482, 483, 484) emanating from the magnet (410), magnetic force lines (482, 483) may be deflected by the magnetic member (460). For example, a portion (482b) of magnetic force line (482) may be formed along the magnetic member (460). For example, a portion (483b) of the magnetic force line (483) may be formed along the magnetic member (460). This may indicate that the magnetic force lines (482, 483) are distorted by the magnetic member (460). For example, the magnetic member (460) may be formed of a magnetic material. As an example without limitation, the magnetic member (460) may be formed of steel. For example, the magnetic force lines (482, 483) may be gathered at the magnetic member (460) and then dispersed again by the magnetic member (460).For example, a portion (482c) of the magnetic field line (482) may have a path similar to that of the magnetic field line (432) of example (400) after coming out of the magnetic member (460). In this case, the magnetic field line (481) may be partially parallel to the portion (482c) of the magnetic field line (482). For example, a portion (483c) of the magnetic field line (483) may have a path similar to that of the magnetic field line (433) of example (400) after coming out of the magnetic member (460). In this case, the magnetic field line (484) may be partially parallel to the portion (483c) of the magnetic field line (483).

[0065] As a magnetic member (460) is placed between the magnet (410) and the magnet (420), some magnetic force lines, including magnetic force lines (482, 483) among the magnetic force lines (481, 482, 483, 484), may have a relatively strong intensity in the region overlapping with the magnetic member (460). In other words, a magnetic field having a stronger intensity may be formed in the region overlapping with the magnetic member (460) compared to the region not overlapping with the magnetic member (460).

[0066] In FIG. 4, the strength of the magnetic field is described in terms of the spacing between the magnetic force lines formed by the magnetic field, but the present disclosure is not limited thereto. For example, the strength of the magnetic field may be defined as magnetic flux density. For example, magnetic flux may be defined as the number of magnetic force lines passing through a specific area (or space). For example, magnetic flux density may be defined as magnetic flux per unit area. In other words, the magnetic flux density for a specific area can be calculated by dividing the magnetic flux passing through the specific area by the unit area. The higher the magnetic flux density, the stronger the magnetic force produced by the magnetic field may be.

[0067] As the distance from the Hall sensor (150) of the electronic device (101) to an external object (e.g., accessory (180) or wireless charging device (190)) increases, the strength of the magnetic field (or magnetic force) caused by the magnet (e.g., magnet (185) or magnet (195)) included in the external object may decrease. In order to increase the strength of the magnetic field caused by the magnet included in the external object, it is necessary to increase the size of the magnet included in the external object. However, this may cause the problem of increasing the size of the external object. In addition, since the external object includes not only the magnet but also a shielding member to reduce the adverse effects of the magnetic field caused by the magnet, there may be limitations in increasing the magnetic flux density directed toward the electronic device (101) from the magnetic field caused by the magnet. Accordingly, the electronic device (101) may find it difficult to detect the magnetic field caused from outside the electronic device (101) through the Hall sensor (150).

[0068] In the present disclosure, a soft magnetic member positioned adjacent to a Hall sensor (150) may be used. For example, an electronic device (101) according to the present disclosure may include a soft magnetic member. In the present disclosure, the soft magnetic member may be referred to as a sensing yoke, a soft magnet, a magnetic member, or a soft magnetic material. For example, by using the soft magnetic member, the electronic device (101) according to the present disclosure can increase the number (or magnetic flux density) of magnetic field lines passing through the Hall sensor (150) (or distort surrounding magnetic field lines to pass through the Hall sensor (150)), thereby allowing the Hall sensor (150) to detect a magnetic field (or magnetic force) more easily and precisely. Accordingly, the electronic device (101) according to the present disclosure can more sensitively detect an external object (e.g., an accessory (180) or a wireless charging device (190)) through a magnetic field (or magnetic force) detected through a Hall sensor (150).

[0069] FIG. 5 illustrates an example of a sectional view of an electronic device including a soft magnetic member for a Hall sensor.

[0070] FIG. 5 illustrates an example (500) of a cross-sectional view of an electronic device (101) in which the electronic device (101) of FIG. 2a is disconnected along CC'. FIG. 5 illustrates an example (500) in which an accessory (180) of the electronic device (101) is mounted on the electronic device (101) for convenience of explanation, but the present disclosure is not limited thereto.

[0071] Referring to example (500), the accessory (180) may be mounted on the electronic device (101). For example, the rear cover (120) of the electronic device (101) may come into contact with the housing (260) of the accessory (180). For example, the rear cover (120) may be positioned in front of (or below) the housing (260). For example, the rear cover (120) positioned in front of (or below) the housing (260) may be indicated as being located in the -y-axis direction relative to the housing (260). Conversely, the housing (260) positioned behind (or above) the rear cover (120) may be indicated as being located in the +y-axis direction relative to the rear cover (120). In the present disclosure, the y-axis may be referenced in the vertical direction, and the x-axis may be referenced in the horizontal direction.

[0072] For example, when the accessory (180) is mounted on the electronic device (101), the rear cover (120) may be covered by the housing (260) of the accessory (180). Even though the rear cover (120) is covered by the housing (260) of the accessory (180), the rear cover (120) may be visible. This may be because the housing (260) of the accessory (180) is translucent. Alternatively, when the accessory (180) is mounted on the electronic device (101), the display (230) of the electronic device (101) may not be covered by the housing (260) of the accessory (180).

[0073] For example, the electronic device (101) may include at least one coil (140) positioned within the housing (110) of the electronic device (101) and located in front of (or below) the rear cover (120). In other words, the at least one coil (140) may be positioned within the housing (110) in an area moved from the rear cover (120) toward the display (230). For example, when an accessory (180) is mounted on the electronic device (101), the magnet (185) of the accessory (180) may be aligned with the at least one coil (140). For example, a wireless charging assembly (250) including at least one coil (140) may be connected to another housing (240).

[0074] For example, the electronic device (101) may include a PCB (220) positioned in front of (or below) at least one coil (140) (or wireless charging assembly (250) or another housing (240)) and disposed within the housing (110). For example, the PCB (220) may be connected (or contacted, coupled) to a bracket (210) of the housing (110). For example, the PCB (220) may include a Hall sensor (150). As an example without limitation, the Hall sensor (150) may be mounted on a part of the PCB (220). For example, the Hall sensor (150) may be mounted on one side of the PCB (220) according to a surface mounted device (SMD).

[0075] For example, the electronic device (101) may include a soft magnetic member (510). For example, the soft magnetic member (510) may have magnetism that is altered by a magnetic field induced from the outside. For example, the relative permeability of the soft magnetic member (510) may be greater than a reference value. For example, the reference value may be 1000. For example, the soft magnetic member (510) may be formed of a material having a relative permeability greater than the reference value. As an example, but not limited to, the soft magnetic member (510) may be formed of steel (e.g., SUS (steel use stainless)) or nickel. For example, as the magnetic field induced from the outside increases, the magnetism of the soft magnetic member (510) may increase. For example, the relative permeability of at least one component disposed within the housing (110) of the electronic device (101) may be lower than the relative permeability of the soft magnetic member (510). For example, the at least one component disposed within the housing (110) of the electronic device (101) may represent a component of the electronic device (101) located on the path through which a magnetic field caused by a magnet (185) passes from the magnet (185) to the soft magnetic member (510) and the Hall sensor (150). Or, for example, the at least one component disposed within the housing (110) of the electronic device (101) may represent a component of the electronic device (101) located around the Hall sensor (150). Accordingly, the soft magnetic member (510) may collect (or distort) magnetic force lines around the soft magnetic member (510). Specific details regarding the magnetic properties of the soft magnetic member (510) are exemplified and explained below with reference to FIG. 7.

[0076] For example, the soft magnetic member (510) may be placed within the housing (110). As an example without limitation, the soft magnetic member (510) may be spaced apart from the Hall sensor (150) and may be in contact with (or attached, supported, connected, or joined to) the bracket (210) of the housing (110). For example, the soft magnetic member (510) may be in contact with (or attached, supported, connected, or joined to) the bracket (210) based on welding. As an example without limitation, the welding may include laser welding. Or, for example, the soft magnetic member (510) may be in contact with (or attached, supported, connected, or joined to) the bracket (210) through an adhesive member. As an example without limitation, the adhesive member may include an adhesive or an adhesive tape. As a non-limiting example, the soft magnetic member (510) may have an L shape. For example, a first portion (511) of the soft magnetic member (510) may extend along the first direction. For example, a second portion (512) of the soft magnetic member (510) may extend along the second direction. However, the present disclosure is not limited thereto. For example, the shape of the soft magnetic member (510) may be formed in a shape different from the L shape (e.g., 'l' or 'ㅡ').

[0077] For example, the soft magnetic member (510) may be positioned horizontally and / or vertically between at least one coil (140) and a Hall sensor (150). In the example (500) of FIG. 5, the horizontal positioning of the soft magnetic member (510) between at least one coil (140) and a Hall sensor (150) may indicate that, with respect to the vertical direction, at least one coil (140), the soft magnetic member (510), and the Hall sensor (150) are positioned in that order. In the example (500) of FIG. 5, the soft magnetic member (510) may not be positioned vertically between at least one coil (140) and a Hall sensor (150). In other words, with respect to the horizontal direction, at least one coil (140), a Hall sensor (150), and a soft magnetic member (510) may be positioned in that order of at least one coil (140), a Hall sensor (150), and a soft magnetic member (510). However, the present disclosure is not limited thereto. In one example, the soft magnetic member (510) may be arranged in the order of at least one coil (140), the soft magnetic member (510), and the Hall sensor (150) with respect to the vertical direction. Specific details regarding the soft magnetic member (510) arranged between at least one coil (140) and the Hall sensor (150) horizontally and / or vertically are illustrated and described below with reference to FIGS. 6a and 6b.

[0078] As a soft magnetic member (510) is positioned horizontally and / or vertically between at least one coil (140) and a Hall sensor (150), the magnetic flux density through which the Hall sensor (150) is located within the housing (110) is relatively increased by the magnetic field generated by the magnet (185) aligned with at least one coil (140). Specific details regarding the magnetic flux density that changes according to the soft magnetic member (510) may be referenced below in FIGS. 8a through 8c.

[0079] FIG. 6a illustrates an example of the positional relationship between a soft magnetic member placed on a bracket of a housing and a Hall sensor.

[0080] FIG. 6a illustrates an example (600) of a positional relationship between a soft magnetic member (510) placed on a bracket (210) of a housing (110) and a Hall sensor (150). The electronic device (101) illustrated in the example (600) may be an example of the electronic device (101) illustrated in the example (500) of FIG. 5. Among the reference numbers illustrated in the example (600) of FIG. 6a, reference numbers identical to those illustrated in the example (500) of FIG. 5 may be used for substantially the same description.

[0081] Referring to example (600), the electronic device (101) may include a housing (110), a rear cover (120), a display (230), at least one coil (140), another housing (240), and a PBA (620). For example, the PBA (620) may include a first PCB (621) and a second PCB (622). For example, the first PCB (621) may be an example of the PCB (220) of FIG. 5 or the PCB (220) of FIG. 2a. For example, the PBA (620) may include an interposer (623) between the first PCB (621) and the second PCB (622). For example, the interposer (623) may be used to connect the first PCB (621) and the second PCB (622). The interposer (623) may be interposed (or embedded, disposed) between the first PCB (621) and the second PCB (622). As an example without limitation, a Hall sensor (150) may be mounted on one side of the first PCB (621). For example, the side of the first PCB (621) on which the Hall sensor (150) is mounted may face the second PCB (622).

[0082] Referring to example (600), virtual lines (611, 612, 613, 614) may be defined for an electronic device (101). For example, a first line (611) may be defined parallel to the y-axis and with respect to at least one coil (140). Defining the first line (611) with respect to at least one coil (140) may mean that the first line (611) meets (or passes) a part of the at least one coil (140). For example, a second line (612) may be defined parallel to the y-axis and with respect to a Hall sensor (150). For example, the second line (612) may be parallel to the first line (611). For example, a third line (613) may be defined parallel to the x-axis and with respect to at least one coil (140). For example, the fourth line (614) may be parallel to the x-axis and defined with respect to the soft magnetic member (510). For example, the third line (613) (or the fourth line (614)) may be perpendicular to the first line (611) (or the second line (612)).

[0083] Referring to example (600), at least one coil (140) may be positioned to the left of the first line (611) (or in the -x-axis direction). Additionally, at least one coil (140) may be positioned behind the third line (613) (or above it, in the +y-axis direction). For example, a Hall sensor (150) may be positioned to the right of the second line (612) (or in the +x-axis direction). Additionally, a Hall sensor (150) may be positioned in front of the third line (613) (or below it, in the -y-axis direction) and behind the fourth line (614) (or above it, in the +y-axis direction). In other words, a Hall sensor (150) may be positioned vertically between the third line (613) and the fourth line (614).

[0084] Referring to example (600), the soft magnetic member (510) may be positioned horizontally between at least one coil (140) and a Hall sensor (150). The at least one coil (140), the soft magnetic member (510), and the Hall sensor (150) may be positioned in the order of at least one coil (140), the soft magnetic member (510), and the Hall sensor (150) with respect to the x-axis. For example, the soft magnetic member (510) may be positioned horizontally between a first line (611) and a second line (612).

[0085] Referring to example (600), the soft magnetic member (510) may not be positioned vertically between at least one coil (140) and the Hall sensor (150). For example, the soft magnetic member (510) may be positioned in front of (or below) at least one coil (140) and in front of (or below) the Hall sensor (150). For example, the soft magnetic member (510) may be positioned below the third line (613) and below the fourth line (614).

[0086] In FIG. 6a, a soft magnetic member (510) disposed horizontally between at least one coil (140) and a Hall sensor (150) is illustrated, but the present disclosure is not limited thereto. For example, an electronic device (101) comprising a soft magnetic member (510) disposed horizontally and vertically between at least one coil (140) and a Hall sensor (150) is illustrated in FIG. 6b.

[0087] FIG. 6b illustrates an example of the positional relationship between a soft magnetic member placed on a bracket of a housing and a Hall sensor.

[0088] FIG. 6b illustrates an example (650) of a positional relationship between a soft magnetic member (510) placed on a bracket (210) of a housing (110) and a Hall sensor (150). The electronic device (101) illustrated in the example (650) may be an example of the electronic device (101) illustrated in the example (500) of FIG. 5. Among the reference numbers illustrated in the example (650) of FIG. 6b, reference numbers identical to those illustrated in the example (500) of FIG. 5 may be used for substantially the same description.

[0089] Referring to example (650), the electronic device (101) may include a housing (110), a rear cover (120), a display (230), at least one coil (140), another housing (240), and a PBA (620). For example, the PBA (620) may include a first PCB (621) and a second PCB (622). For example, the first PCB (621) may be an example of the PCB (220) of FIG. 5 or the PCB (220) of FIG. 2a. For example, the PBA (620) may include an interposer (623) between the first PCB (621) and the second PCB (622). For example, the interposer (623) may be used to connect the first PCB (621) and the second PCB (622). The interposer (623) may be contained (or embedded, disposed) between the first PCB (621) and the second PCB (622). As an example without limitation, a Hall sensor (150) may be mounted on one side of the first PCB (621). For example, the side of the first PCB (621) on which the Hall sensor (150) is mounted may face the second PCB (622).

[0090] Referring to example (650), virtual lines (611, 612, 613, 615) may be defined for an electronic device (101). For example, a first line (611) may be defined parallel to the y-axis and with respect to at least one coil (140). Defining the first line (611) with respect to at least one coil (140) may mean that the first line (611) meets (or passes) a part of the at least one coil (140). For example, a second line (612) may be defined parallel to the y-axis and with respect to a Hall sensor (150). For example, the second line (612) may be parallel to the first line (611). For example, a third line (613) may be defined parallel to the x-axis and with respect to at least one coil (140). For example, the fifth line (615) may be parallel to the x-axis and defined with respect to the soft magnetic member (510). The fifth line (615) of example (650) may differ from the fourth line (614) of example (600) as the position in which the soft magnetic member (510) is placed within the housing (110) changes. For example, the third line (613) (or the fifth line (615)) may be perpendicular to the first line (611) (or the second line (612)).

[0091] Referring to example (650), at least one coil (140) may be positioned to the left of the first line (611) (or in the -x-axis direction). Additionally, at least one coil (140) may be positioned behind the third line (613) (or above it, in the +y-axis direction). For example, a Hall sensor (150) may be positioned to the right of the second line (612) (or in the +x-axis direction). Additionally, a Hall sensor (150) may be positioned in front of the third line (613) (or below it, in the -y-axis direction) and in front of the fifth line (615) (or below it, in the -y-axis direction).

[0092] Referring to example (650), the soft magnetic member (510) may be positioned horizontally and vertically between at least one coil (140) and a Hall sensor (150). The at least one coil (140), the soft magnetic member (510), and the Hall sensor (150) may be positioned in the order of at least one coil (140), the soft magnetic member (510), and the Hall sensor (150) with respect to the x-axis. For example, the soft magnetic member (510) may be positioned horizontally between a first line (611) and a second line (612). Additionally, the at least one coil (140), the soft magnetic member (510), and the Hall sensor (150) may be positioned in the order of at least one coil (140), the soft magnetic member (510), and the Hall sensor (150) with respect to the y-axis. For example, the soft magnetic member (510) can be vertically positioned between the third line (613) and the fifth line (615).

[0093] Referring to Example (650), unlike the soft magnetic member (510) of Example (600), the soft magnetic member (510) may be supported (or contacted, attached) by a housing (240) other than the bracket (210) of the housing (110). For example, the soft magnetic member (510) of Example (650) may have an inverted L shape. However, the present disclosure is not limited thereto. For example, in Example (650), the soft magnetic member (510) may be supported (or contacted, attached) by another component (e.g., wireless charging assembly (250)) within the electronic device (101) other than the other housing (240).

[0094] Example (600) may represent a case where the direction of the magnetic field caused by the magnet (e.g., magnet (185) or magnet (195) of FIG. 1) of an external object (e.g., accessory (180) or wireless charging device (190) of FIG. 1) located adjacent to the electronic device (101) is a first direction. Alternatively, Example (650) may represent a case where the direction of the magnetic field caused by the magnet (e.g., magnet (185) or magnet (195) of FIG. 1) of an external object (e.g., accessory (180) or wireless charging device (190) of FIG. 1) located adjacent to the electronic device (101) is a second direction opposite to the first direction. For example, the direction of the magnetic field may be determined based on the first polarity of the outermost part of the magnet of the external object (e.g., outermost part (185-1) in FIG. 2b) and the second polarity of the innermost part (e.g., innermost part (185-2) in FIG. 2b). As a non-limiting example, the first direction may be the direction of the magnetic field where the first polarity is N and the second polarity is S, in the direction from at least one coil (140) toward the Hall sensor (150). Alternatively, the second direction may be the direction of the magnetic field where the first polarity is S and the second polarity is N, in the direction from the Hall sensor (150) toward at least one coil (140).

[0095] Referring to FIGS. 6a and 6b, a soft magnetic member (510) can be used to more easily detect a magnetic field caused by a magnet (e.g., magnet (185) or magnet (195) of FIG. 1) that is aligned with at least one coil (140) of the Hall sensor (150). For example, the soft magnetic member (510) can change (or distort) the magnetic field so that the magnetic field caused by the magnet passes more through the Hall sensor (150). For differences in magnetic properties between the soft magnetic member (510) and the magnet, refer to FIG. 7 below.

[0096] Figure 7 illustrates an example of a hysteresis curve of a soft magnetic member.

[0097] FIG. 7 illustrates an example (700) of a hysteresis curve of a soft magnetic member (e.g., the soft magnetic member (510) of FIG. 5) and an example (750) of a hysteresis curve of a hard magnetic member (e.g., the magnet (185) or magnet (195) of FIG. 1). The horizontal axis of each example (700) and example (750) may be magnetic field strength (H) (unit: A (ampere) / m (meter)), and the vertical axis may be magnetic flux density (B) (unit: T (tesla)).

[0098] Referring to Example (700), a hysteresis curve (710) of a soft magnetic member is illustrated. For example, the hysteresis curve (710) represents the magnetic flux density according to the magnetic field of the soft magnetic member. The hysteresis curve (710) and the vertical axis may meet at point (711). Additionally, the hysteresis curve (710) and the horizontal axis may meet at point (712). For example, point (711) may represent the residual induction of the soft magnetic member. The residual induction may represent the maximum magnetic flux output from the soft magnetic member when the magnetizing force is zero. For example, point (712) may represent the coercive field strength. The coercive field strength may represent the magnitude of the force required to completely eliminate the magnetism of the soft magnetic member.

[0099] Referring to Example (750), a hysteresis curve (720) of a hard magnetic member is illustrated. For example, the hysteresis curve (720) represents the magnetic flux density according to the magnetic field of the hard magnetic member. The hysteresis curve (720) and the vertical axis may meet at point (721). Additionally, the hysteresis curve (720) and the horizontal axis may meet at point (722). For example, point (721) may represent the residual induction of the hard magnetic member. The residual induction may represent the maximum magnetic flux output from the hard magnetic member when the magnetizing force is zero. For example, point (722) may represent the coercive force. The coercive force may represent the magnitude of the force required to completely eliminate the magnetism of the hard magnetic member.

[0100] Referring to examples (700) and (750), the value of point (711) may be lower than the value of point (721). In other words, the residual induction of the soft magnetic member may be lower than the residual induction of the hard magnetic member. Additionally, the value of point (712) may be lower than the value of point (722). In other words, the coercivity of the soft magnetic member may be lower than the coercivity of the hard magnetic member.

[0101] Referring to the above description, the soft magnetic member can be magnetized or demagnetized more easily by an external magnetic field compared to the hard magnetic member. For example, the soft magnetic member can be demagnetized relatively easily when an externally generated magnetic field is not applied to the soft magnetic member. Also, for example, the soft magnetic member can be magnetized relatively easily when an externally generated magnetic field is applied to the soft magnetic member. Accordingly, even if the electronic device (101) contains the soft magnetic member (510) within the housing (110), the impact on the components inside the electronic device (101) may be low because there is no magnetic field generated from the soft magnetic member (510) or the strength of the magnetic field is weak. Additionally, as the electronic device (101) includes a soft magnetic member (510) within the housing (110), the soft magnetic member (510) is magnetized by a magnetic field generated from outside the electronic device (101), and the magnetic flux density (or magnetic field strength) passing through the area (or space) within the housing (110) where the Hall sensor (150) is placed can be increased.

[0102] Specific details regarding the magnetic flux density increased by the soft magnetic member (510) located adjacent to the Hall sensor (150) may be referenced below in FIGS. 8a to 8c.

[0103] FIGS. 8a to 8c illustrate examples of changes in magnetic flux density according to the magnetic field of the area where the Hall sensor is placed, based on a soft magnetic member located adjacent to the Hall sensor.

[0104] FIG. 8a illustrates an example (800) of a soft magnetic member (510) positioned adjacent to a Hall sensor (150). In the example (800), an electronic device (101) equipped with an accessory (180) is illustrated. For convenience of explanation, some of the components of the electronic device (101) of the example (800) may not be illustrated.

[0105] Referring to example (800), the electronic device (101) may include a soft magnetic member (510) and a Hall sensor (150). In an example that is not limited, the Hall sensor (150) may be included (or mounted) on a PCB (e.g., PCB (220) of FIG. 2a, PCB (220) of FIG. 5, PBA (620) of FIG. 6a and FIG. 6b). In an example that is not limited, the soft magnetic member (510) may be spaced apart from the Hall sensor (150) and supported by a bracket (210) of the housing (110). In an example that is not limited, the soft magnetic member (510) may have an L shape. For example, a soft magnetic member (510) having an L shape may include a portion extending along the y-axis (e.g., the first portion (511) of FIG. 5) and a portion extending along the x-axis (e.g., the second portion (512) of FIG. 5).

[0106] Referring to example (800), a magnet (185) of an accessory (180) mounted on an electronic device (101) can form a magnetic field. For example, among the magnetic fields formed by the magnet (185), the magnetic field formed from the remaining portion excluding the region (280) of the magnet (185) can be shielded by a shielding member (270). As the magnetic field formed from the remaining portion of the magnet (185) is shielded by the shielding member (270), it may not be applied into the electronic device (101). In contrast, the magnetic field (810) formed from the region (280) of the magnet (185) may be applied into the electronic device (101) as it is not shielded by the shielding member (270). At this time, the area (280) not shielded by the shielding member (270) may correspond to the Hall sensor (150) and the soft magnetic member (510) with respect to the z-axis direction. In other words, when the accessory (180) is mounted on the electronic device (101), the area (280) may be aligned with the Hall sensor (150) and the soft magnetic member (510) with respect to the z-axis.

[0107] For example, the magnetic field (810) may extend from a portion having a first polarity (e.g., N pole) (e.g., the outermost portion (185-1) in FIG. 2b) to a portion having a second polarity (e.g., S pole) (e.g., the innermost portion (185-2) in FIG. 2b). For example, the magnetic field (810) extending from the portion having the first polarity toward the portion having the second polarity may be defined by a first magnetic field line (811), a second magnetic field line (812), and a third magnetic field line (813). In the example (800) of FIG. 8a, magnetic field lines (811, 812, 813) forming a single closed loop are shown for convenience of explanation, but the present disclosure is not limited thereto. For example, the magnetic field (810) formed by the magnet (185) may be defined by magnetic field lines forming a plurality of closed loops. For example, the first magnetic force line (811) may extend from the magnet (185) to the soft magnetic member (510). For example, the second magnetic force line (812) may extend from the soft magnetic member (510) to the Hall sensor (150). For example, the third magnetic force line (813) may extend from the Hall sensor (150) to the magnet (185).

[0108] Examples of changes in magnetic flux density according to the magnetic field (810) in an area within an electronic device (101) (or housing (110)) where a Hall sensor (150) is placed, based on a soft magnetic member (510), may be referenced below in FIGS. 8b and FIGS. 8c.

[0109] FIG. 8b illustrates an example (820) of magnetic flux density in an area (829) where a Hall sensor (150) is placed in an electronic device (101) that does not include a soft magnetic member (510), and an example (830) of magnetic flux density in an area (839) where a Hall sensor (150) is placed in an electronic device (101) that includes a soft magnetic member (510). The examples (820) and (830) may represent a perspective view of an electronic device (101) rotated 180° clockwise with respect to the z-axis in the example (800) of FIG. 8a.

[0110] Referring to example (820), an area (827) of an electronic device (101) that does not include a soft magnetic member (510) and an area (829) of a Hall sensor (150) that corresponds to an area (837) in which a soft magnetic member (510) is placed within an electronic device (101) that includes a soft magnetic member (510) are shown. For example, a magnetic flux (821) passing through area (827) and a magnetic flux (822) passing through area (829) may be defined according to a magnetic field (810) formed by a magnet (185). In example (820), the area (827) may be defined as the location of a member in an electronic device (101) that includes a member having a relative permeability less than the reference value and having substantially the same shape as the soft magnetic member (510).

[0111] Referring to example (830), an area (837) in which a soft magnetic member (510) is placed and an area (839) in which a Hall sensor (150) is placed are shown within an electronic device (101) including a soft magnetic member (510). For example, a magnetic flux (831) passing through area (837) and a magnetic flux (832) passing through area (839) can be defined according to the magnetic field (810) formed by a magnet (185).

[0112] Referring to examples (820) and (830), the density of magnetic flux (821) (or magnetic flux density) may be lower than the density of magnetic flux (831) (or magnetic flux density). The density of magnetic flux (822) (or magnetic flux density) may be lower than the density of magnetic flux (832) (or magnetic flux density). By example, without limitation, the density of magnetic flux (831) and the density of magnetic flux (832) may be about 30% higher than the density of magnetic flux (821) and the density of magnetic flux (822). In other words, as the soft magnetic member (510) causes the magnetic field (810) to pass further through the soft magnetic member (510) and causes the magnetic field (810) to pass further through the Hall sensor (150), the density of magnetic flux (832) passing through the Hall sensor (150) may be increased.

[0113] FIG. 8c illustrates examples (850, 860) of the example (820) and example (830) of FIG. 8b viewed from the perspective of the electronic device (101). Example (850) illustrates examples of magnetic field lines defining the magnetic field caused by the magnet (185) when the example (820) is viewed from the perspective of the electronic device (101). Example (860) illustrates examples of magnetic field lines defining the magnetic field caused by the magnet (185) when the example (830) is viewed from the perspective of the electronic device (101).

[0114] Referring to example (850), region (851) may represent a region including region (827) and region (829) of example (820). For example, a magnetic field line (852) within region (851) may be an example of a magnetic field line extending from region (827) to region (829). Referring to example (860), region (861) may represent a region including region (837) and region (839) of example (830). For example, a magnetic field line (862) within region (861) may be an example of a magnetic field line extending from region (837) to region (839).

[0115] Referring to examples (850) and (860), the magnetic field line (862) of region (861) may be formed to be directed more directly from region (837) to region (839) than the magnetic field line (852) of region (851) directed from region (827) to region (829). In other words, when the soft magnetic member (510) is included, the magnetic flux density (or magnetic field strength) directed from the soft magnetic member (510) to the Hall sensor (150) may be increased compared to when the soft magnetic member (510) is not included. Additionally, referring to examples (850) and (860), the magnetic field line formed outside region (861) may be substantially the same as the magnetic field line formed outside region (851). In other words, in an area inside the electronic device (101) that is relatively far from the soft magnetic member (510), there may be substantially no change in magnetic properties caused by the soft magnetic member (510).

[0116] Referring to FIGS. 8a through 8c, the electronic device (101) can increase the magnetic flux density passing through the Hall sensor (150) while minimizing (or reducing) the impact on components inside the electronic device (101) by including a soft magnetic member (510).

[0117] In FIGS. 5 through 8c, it is assumed that the soft magnetic member (510) is supported by the housing (110) (or bracket (210)) of the electronic device (101), but the present disclosure is not limited thereto. For example, the electronic device (101) may include a soft magnetic member that is mounted or attached (or supported) to another component within the housing (110). Specific details regarding this are illustrated and described below with reference to FIGS. 9a and 9b.

[0118] FIGS. 9a and 9b illustrate examples of positional relationships between a soft magnetic member and a Hall sensor included in a printed circuit board (PCB).

[0119] FIGS. 9a and 9b illustrate examples (900, 950) of an electronic device (101) comprising a soft magnetic member included in a PBA (620). Unlike the electronic device (101) of FIGS. 9a and 9b which comprises a soft magnetic member (510) supported (or attached, contacted) by a bracket (210) of the housing (110) of FIG. 5, the electronic device (101) may comprise a soft magnetic member included in a PBA (620). FIGS. 9a and 9b illustrate a soft magnetic member included in a PBA (620) comprising a plurality of PCBs, but the present disclosure is not limited thereto. For example, the electronic device (101) may comprise a single PCB, and the single PCB may comprise a soft magnetic member.

[0120] Referring to examples (900) and (950), the electronic device (101) may include a housing (110), a rear cover (120), a display (230), at least one coil (140), another housing (240), and a PBA (620). For example, the PBA (620) may include a first PCB (621) and a second PCB (622). Among the reference numbers shown in the example (900) of FIG. 9a and the example (950) of FIG. 9b, the same reference numbers as those shown in the example (600) of FIG. 6a may be used for substantially the same description.

[0121] Referring to example (900), the electronic device (101) may include a soft magnetic member (910). For example, the soft magnetic member (910) may be included in the PBA (620). As an example without limitation, the soft magnetic member (910) may be mounted on a first PCB (621) of the PBA (620). For example, the soft magnetic member (910) may be mounted on one side of the first PCB (621) via a clip. Or, for example, the soft magnetic member (910) may be mounted on said one side of the first PCB (621) via an adhesive member. As an example without limitation, said adhesive member may include an adhesive or adhesive tape. That one side of the first PCB (621) on which the soft magnetic member (910) is mounted may face the second PCB (622). For example, the soft magnetic member (910) may be spaced apart from the Hall sensor (150) and may at least partially wrap around the Hall sensor (150) from the outside of the Hall sensor (150). As a non-limiting example, when viewed from the z-axis direction, the soft magnetic member (910) may have a 'C' shape.

[0122] Referring to example (950), the electronic device (101) may include a soft magnetic member (960). For example, the soft magnetic member (960) may be included in the PBA (620). As an example without limitation, the soft magnetic member (960) may be attached to a second PCB (622) of the PBA (620). For example, the soft magnetic member (910) may be mounted on one side of the second PCB (622) via a clip. Or, for example, the soft magnetic member (960) may be mounted on said one side of the second PCB (622) via an adhesive member. As an example without limitation, said adhesive member may include an adhesive or adhesive tape. That side of the second PCB (622) on which the soft magnetic member (960) is mounted may face the first PCB (621). For example, the soft magnetic member (960) may be spaced apart from the Hall sensor (150) mounted on one side of the first PCB (621). For example, the one side of the first PCB (621) on which the Hall sensor (150) is mounted may face the second PCB (622). As a non-limiting example, when viewed from the z-axis direction, the soft magnetic member (960) may have an 'L' shape.

[0123] Referring to FIGS. 1 through 9b, the present disclosure may utilize a soft magnetic member positioned adjacent to a Hall sensor (150) (e.g., the soft magnetic member (510) of FIG. 5, FIG. 6a, or FIG. 6b, the soft magnetic member (910) of FIG. 9a, and the soft magnetic member (960) of FIG. 9b). For example, an electronic device (101) according to the present disclosure may include the soft magnetic member. In the present disclosure, the soft magnetic member may be referred to as a sensing yoke, a soft magnet, a magnetic member, or a soft magnetic material. For example, the electronic device (101) according to the present disclosure can detect a magnetic field (or magnetic force) more easily and precisely by using the soft magnetic member to increase the number (or magnetic flux density) of magnetic field lines passing through the Hall sensor (150) (or by distorting surrounding magnetic field lines to pass through the Hall sensor (150). Accordingly, the electronic device (101) according to the present disclosure can detect an external object (e.g., an accessory (180) or a wireless charging device (190)) more sensitively through the magnetic field (or magnetic force) detected through the Hall sensor (150).

[0124] The effects obtainable from the present disclosure are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which the present disclosure belongs from the description below.

[0125] FIG. 10 is a block diagram of an electronic device in a network environment according to various embodiments.

[0126] Referring to FIG. 10, in a network environment (1000), an electronic device (1001) may communicate with an electronic device (1002) through a first network (1098) (e.g., a short-range wireless communication network) or with at least one of an electronic device (1004) or a server (1008) through a second network (1099) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1001) may communicate with the electronic device (1004) through a server (1008). According to one embodiment, the electronic device (1001) may include a processor (1020), memory (1030), input module (1050), sound output module (1055), display module (1060), audio module (1070), sensor module (1076), interface (1077), connection terminal (1078), haptic module (1079), camera module (1080), power management module (1088), battery (1089), communication module (1090), subscriber identification module (1096), or antenna module (1097). In some embodiments, at least one of these components (e.g., connection terminal (1078)) may be omitted from the electronic device (1001), or one or more other components may be added. In some embodiments, some of these components (e.g., sensor module (1076), camera module (1080), or antenna module (1097)) may be integrated into a single component (e.g., display module (1060)).

[0127] The processor (1020) can, for example, execute software (e.g., program (1040)) to control at least one other component (e.g., hardware or software component) of the electronic device (1001) connected to the processor (1020) and can perform various data processing or operations. According to one embodiment, as at least part of the data processing or operations, the processor (1020) can store commands or data received from other components (e.g., sensor module (1076) or communication module (1090)) in volatile memory (1032), process the commands or data stored in volatile memory (1032), and store the resulting data in non-volatile memory (1034). According to one embodiment, the processor (1020) may include a main processor (1021) (e.g., a central processing unit or an application processor) or an auxiliary processor (1023) that can operate independently or together with it (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor).

If the electronic device (1001) detects user movement through an IMU sensor, the processor of the electronic device (1001) can correct the rendering data received from the external electronic device (1002) based on the movement information and output it to the display module. Alternatively, the external electronic device (1002) can transmit the movement information to request rendering so that the screen data is updated accordingly.
