Description

Electronic device including a magnetic sensor

[0001] An embodiment of the present disclosure relates to an electronic device comprising a magnetic sensor.

[0002] Recently, electronic devices have been becoming increasingly smaller, while their functions have been becoming increasingly diverse. Consequently, electrical components embedded in electronic devices can be positioned with increasingly narrow spacing from surrounding structures, and various methods are being sought to efficiently arrange each electrical component.

[0003] Electronic devices can perform wireless charging or contactless charging functions using wireless power transfer technology. Wireless power transfer technology is a technology that converts electrical energy into electromagnetic waves with frequency and transmits energy wirelessly to a load (e.g., an external electronic device) without transmission lines. Wireless power transfer technology may be a technology in which power is wirelessly transmitted from a power transmitting device to a power receiving device (e.g., an electronic device) without a connection via a separate connector between the power receiving device (e.g., an electronic device) and the power transmitting device (e.g., an external charging device), thereby charging the battery of the power receiving device. Wireless power transfer technology may include magnetic induction and magnetic resonance methods, and may also include various other types of wireless power transfer technology.

[0004] The information described above may be provided as background art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art in relation to the present disclosure.

[0005] A magnetic induction wireless power transmission system transmits power using a magnetic field induced in a coil. By utilizing the magnetic field generated from the current flowing through the transmitting coil, an electromotive force can be generated in the receiving coil to induce a current. Energy can be supplied from a power transmitting device (e.g., an external charging device) to a power receiving device (e.g., an electronic device). Based on the energy supplied from the power transmitting device, the power receiving device can perform a wireless charging function for a battery.

[0006] According to one embodiment, the electronic device may support a magnetic power profile (MPP) charging method based on the wireless charging standard Qi2. For example, in the MPP charging method, alignment between the transmitting coil and the receiving coil is important, and to this end, the transmitting coil of the power transmitting device and the receiving coil of the power receiving device need to be positioned in an accurate position relative to each other. For example, the MPP charging method may support a high-speed charging function of approximately 15W under the condition that the transmitting coil and the receiving coil are aligned at a set position using a magnetic member.

[0007] According to one embodiment, an electronic device may have an annular magnet (e.g., an annular magnet that at least partially wraps the charging coil) positioned based on the arrangement structure of the battery and the charging coil (e.g., an induction coil, or a receiving coil). The electronic device may include a magnetic sensor (e.g., a Hall sensor) for determining the presence or absence of the annular magnet. For example, the position of the magnetic sensor may be determined by considering the location where the annular magnet is positioned. Since the internal space of the electronic device is narrow, there may be difficulties in positioning the magnetic sensor.

[0008] According to one embodiment, when an electronic device supports an MPP charging method, the electronic device requires a magnetic sensor for detecting an annular magnet and can provide an efficient placement structure for the magnetic sensor.

[0009] The technical tasks intended to be accomplished in this document are not limited to those mentioned above, and other technical tasks not mentioned will be clearly understood by those skilled in the art to which this document belongs from the description below.

[0010] According to one embodiment, the electronic device may include a housing comprising a first surface, a second surface facing the first surface, and a side surrounding the space between the first surface and the second surface; a battery disposed in the space; a wireless charging coil disposed between the battery and the second surface in the space; a processor comprising a processing circuit; a first printed circuit board on which the processor is disposed; a second printed circuit board electrically connected to the battery and the first printed circuit board and disposed within a recess space in which the battery is fixed; and at least one Hall sensor disposed on the second printed circuit board and adjacent to the wireless charging coil, configured to detect a magnetic force generated by a magnetic member attached to the second surface from the outside of the electronic device.

[0011] According to one embodiment, the electronic device may include a first housing comprising a first surface, a second surface facing the first surface, and a side surrounding the space between the first surface and the second surface; a second housing foldably coupled to the first housing through a hinge device; a battery disposed in the space of the first housing; a wireless charging coil disposed between the battery and the second surface within the space of the first housing; a processor comprising a processing circuit; a first printed circuit board on which the processor is disposed; a second printed circuit board electrically connected to the battery and the first printed circuit board and disposed within a recess space in which the battery is fixed; and at least one Hall sensor disposed on the second printed circuit board and adjacent to the wireless charging coil, configured to detect a magnetic force generated by a magnetic member attached to the second surface from the outside of the electronic device.

[0012] According to one embodiment, the electronic device supports a magnetic power profile (MPP) charging method and may include a magnetic sensor for detecting an annular magnet, which is an essential component for MPP charging. The placement location of the magnetic sensor may be determined by considering the location where the annular magnet is placed. To ensure charging stability for the battery, the electronic device may include a protection circuit module electrically connected to the battery. For example, some area corresponding to the placement location of the annular magnet may overlap at least partially with the protection circuit module. The magnetic sensor may be placed based on the area where the protection circuit module and the annular magnet overlap, and may detect the presence or absence of the annular magnet.

[0013] According to one embodiment, the magnetic sensor can be placed flatly based on a protection circuit board for the battery. The magnetic sensor can be freely placed within the area where the protection circuit board and the annular magnet overlap. The design freedom regarding the placement location of the magnetic sensor can be increased.

[0092] According to one embodiment, at least one magnetic sensor (511) (e.g., a Hall sensor, or a Hall IC) may be placed on a protection circuit board (510) (e.g., a second printed circuit board). The second printed circuit board (510) may be physically separated from the first printed circuit board (430a) (e.g., a main board) and the third printed circuit board (430) (e.g., a sub-board). At least one magnetic sensor (511) may detect magnetic force generated by a magnetic member (520) attached to a second surface (e.g., a rear surface) from the outside of the electronic device (400). According to one embodiment, the electronic device (400) may recognize that the magnetic member (520) is placed on the second surface of the electronic device (400) based on at least one magnetic sensor (511).

[0093] Referring to FIG. 4, a second printed circuit board (510) (e.g., a protection circuit board) is shown to be positioned in the Y-axis direction toward the third side (423) centered on the battery (450), but is not limited thereto. According to one embodiment, the second printed circuit board (510) may include at least one protection circuit board and may be positioned in a direction toward one of the first side (421) to the fourth side (424) centered on the battery (450).

For example, the magnetic sensor (511) may include a Hall sensor (a Hall IC).

[0095] According to one embodiment, the electronic device (400) may include an induction coil (530) (e.g., a receiving coil, or a wireless charging coil) for wireless charging of the battery (450). For example, the induction coil (530) may be placed between the battery (450) and the rear cover (380) and may receive power provided from a transmitting coil of an external charging device. The more accurate the alignment between the induction coil (530) of the electronic device (400) and the transmitting coil of the external charging device, the higher the charging efficiency for the battery (450). The electronic device (400) may use the induction coil (530) to obtain power provided from the external charging device and perform a charging function for the battery (450) based on the obtained power.

[0096] According to one embodiment, the electronic device (400) can ensure that the transmitting coil of an external charging device is accurately positioned in alignment with the induction coil (530) (e.g., a receiving coil, or a wireless charging coil) of the electronic device (400) for efficient charging of the battery (450). When viewed from the rear of the electronic device (400), if the induction coil (530) (e.g., a receiving coil, or a wireless charging coil) and the transmitting coil of the external charging device are positioned to overlap, the charging efficiency may be improved. A magnetic member (520) for fixing the position of the transmitting coil may be provided on the rear cover (380) of the electronic device (400) so that the transmitting coil of the external charging device is accurately positioned in alignment with the induction coil (530). An attractive force may act between the magnetic member (520) and the magnet included in the external charging device. According to one embodiment, when an external charging device is attached to an electronic device (400) by means of an attractive force between magnetic members (520), the transmitting coil of the external charging device and the receiving coil of the electronic device (400) may be arranged in a form that overlaps each other.

[0097] According to one embodiment, the magnetic member (520) of the electronic device (400) may be positioned so as not to be in physical contact with the induction coil (530). For example, the position of the magnetic member (520) may be determined such that, when viewed from the rear of the electronic device (400), the induction coil (530) and the magnetic member (520) do not overlap at least partially with each other. According to one embodiment, the magnetic member (520) may be included in the rear cover (211) of the electronic device (400) or in an accessory cover mounted on the rear (210B) of the electronic device (400).

[0098] According to one embodiment, the electronic device (400) may include at least one magnetic sensor (511) for detecting the presence or absence of a magnetic member (520). For example, the at least one magnetic sensor (511) may be placed on a second printed circuit board (510) for a battery (450) and may detect the presence or absence of the magnetic member (520). For example, when viewed from the rear (210B) of the electronic device (400), the at least one magnetic sensor (511) may be placed on the protection circuit board (510) based on an area where the magnetic member (520) and the second printed circuit board (510) overlap each other.

In another example, the electronic device (400) cannot perform the MPP charging function in response to a situation where the magnetic member (520) is not placed. If the placement of the magnetic member (520) on the rear surface is not confirmed, the electronic device (400) can perform an extended power profile (EPP) charging function (e.g., a second wireless charging method). For example, the MPP charging function may be a wireless charging method with relatively improved wireless charging efficiency compared to the EPP charging function. The electronic device (400) can perform the MPP charging function under the condition that the magnetic member (520) is placed.

[0100] According to one embodiment, the electronic device (400) can determine the presence of a magnetic member (520) using at least one magnetic sensor (511) and can support a magnetic power profile (MPP) charging function (e.g., a first wireless charging method) based on the magnetic member (520).

For example, the accessory may be designed in such a way that a magnetic member (e.g., a magnet) is positioned corresponding to the location where the at least one magnetic sensor (511) is placed. By detecting the magnetic member included in the accessory, the at least one magnetic sensor (511) may determine that the accessory is at least partially coupled to or placed on the electronic device (400).

[0102] In one embodiment, a first printed circuit board (430a) (e.g., a main board) may be electrically connected to a third printed circuit board (430) (e.g., a sub-board) via an electrical connection member (440). In one embodiment, the electrical connection member (440) may include an RF coaxial cable or a flexible printed circuit board (FRC; FPCB (flexible printed circuit board) type RF cable). In one embodiment, a wireless communication circuit (e.g., the wireless communication module (192) of FIG. 1) may be placed on the third printed circuit board (430).

[0103] According to various embodiments, the side member (420) may include a conductive member (425) as a conductor, segmented through segmented portions (4211, 4221). For example, the conductive member (425) may be segmented from the surrounding metal material (420a) through a first segmented portion (4211) disposed in at least part of the first side (421) and a second segmented portion (4221) disposed in at least part of the second side (422). In one embodiment, the electronic device (400) may include a third segmented portion (4212) spaced apart from the first segmented portion (4211) on the first side (421) and another conductive member (426) segmented from the surrounding metal material (420a) through the first segmented portion (4211). In one embodiment, the third printed circuit board (430) can be electrically connected to a point of the conductive member (425) and a wireless communication circuit (e.g., the wireless communication module (192) of FIG. 1) through an assembly process in which the third printed circuit board (430) is mounted in the internal space (4001) of the housing (410). For example, the conductive member (425) can be used as a radiator of an antenna in the low band (LB) by being electrically connected to the wireless communication circuit (e.g., the wireless communication module (192) of FIG. 1) of the third printed circuit board (430).

[0106] According to one embodiment, a protection circuit board (510) (PCM, protection circuit module) (e.g., a second printed circuit board) may be electrically connected to a battery (550) (e.g., the battery (450) of FIG. 4) and may function to prevent problems related to charging of the battery (550) (e.g., over-discharge, over-charge, over-current, or cell balancing). The protection circuit board (510) (e.g., a second printed circuit board) may be physically separated from the first printed circuit board (e.g., the first printed circuit board (430a) of FIG. 4, main board) and may manage functions and operations for the battery (550) at least partially. For example, the protection circuit board (510) may perform an over-discharge protection voltage, an over-charge protection voltage, an over-current protection, and / or a short protection. The over-discharge protection function may be a function that preemptively blocks the discharge of the battery (550) to prevent a situation where the battery (550) is damaged by over-discharging. The overcharge protection function may be a function that preemptively blocks the charging of the battery (550) to prevent swelling, which may occur when the battery (550) is overcharged above a protection voltage and a chemical reaction begins. The overcurrent cutoff function may be a function that blocks the flow of current exceeding a certain value to prevent a situation where the battery (550) is damaged due to an overcurrent being applied to the battery (550) caused by a malfunction of an electronic device (e.g., the electronic device (400) of FIG. 4). The short-circuit protection function may be a function that prevents a situation where the battery (550) is damaged when an external load is short-circuited, thereby preventing a fire caused by the short circuit.

[0107] Referring to FIG. 5a, at least one electrical component may be disposed on the front surface (5101) of the protection circuit board (510). For example, when a battery (550) to which the protection circuit board (510) is connected is disposed in the internal space of an electronic device (400), the front surface (5101) of the protection circuit board (510) may be disposed facing the front surface (e.g., the first surface (210A) of FIG. 2a). For example, the front surface (5101) of the protection circuit board (510) may be disposed facing a display (e.g., the display (201) of FIG. 2a, the display (330) of FIG. 3).

[0108] Referring to FIG. 5b, at least one magnetic sensor (511) may be disposed on the rear surface (5102) of the protection circuit board (510). For example, when a battery (550) to which the protection circuit board (510) is connected is disposed in the internal space of an electronic device (400), the rear surface (5102) of the protection circuit board (510) may be disposed facing the rear surface (e.g., the second surface (210B) of FIG. 2b). For example, the rear surface (5102) of the protection circuit board (510) may be disposed facing an induction coil (e.g., the induction coil (530) of FIG. 4, or a wireless charging coil) and a rear cover (e.g., the rear cover (380) of FIG. 3).

[0109] Referring to FIG. 5c, the protection circuit board (510) may be electrically connected to the battery (550), and at least one magnetic sensor (511) may be disposed on the rear surface of the protection circuit board (510). According to one embodiment, the placement location of the at least one magnetic sensor (511) may not be limited to a specific location such as the front (5101) or the rear (5102). For example, the at least one magnetic sensor (511) may perform the operation of detecting a magnetic member (e.g., the magnetic member (520) of FIG. 4) disposed on the rear cover (380) of the electronic device (400). The location of the at least one magnetic sensor (511) may be determined (e.g., the front (5102) or the rear (5102)) depending on the area where the magnetic member (520) is located, but may not be limited thereto.

[0110] FIG. 6 is a block diagram of an electronic device including a magnetic sensor disposed on a protection circuit board according to one embodiment of the present disclosure.

[0111] The electronic device (601) of FIG. 6 is at least partially similar to the electronic device (101) of FIG. 1 and the electronic device (200) of FIG. 2a, or may further include other embodiments of the electronic devices (101, 200).

[0112] Referring to FIG. 6, the electronic device (601) may include a substrate (e.g., the first substrate (341) and / or the second substrate (342) of FIG. 3) comprising a processor (AP) (611) (e.g., an application processor) and a power management circuit (PMIC) (612), and a battery (620) (e.g., the battery (450) of FIG. 4). According to one embodiment, the electronic device (601) may include various electrical components in addition to the electrical components shown in FIG. 6.

[0113] Referring to FIG. 6, the battery (620) may include a battery cell (622) (e.g., a lithium-ion battery that uses electrical energy by charging or discharging) and a protection circuit board (621) (e.g., the protection circuit board (510) of FIG. 5a) for controlling the functions of the battery cell (622) (e.g., over-discharge protection, over-charge protection, over-current cutoff, and / or short-circuit protection). For example, the protection circuit board (621) may be electrically connected to the battery cell (622) to control functions related to charging or discharging the battery cell (622). According to one embodiment, at least one electrical element (623) and a magnetic sensor (630) (e.g., the magnetic sensor (511) of FIG. 4) may be disposed on the protection circuit board (621).

[0114] Referring to FIG. 6, in operations 641 and 642, the processor (611) of the electronic device (601) can at least partially control the power management circuit (612) so that power supplied from the battery (620) to the power management circuit (612) is supplied to various components of the electronic device (601). For example, the processor (611) can control the power management circuit (612) to supply power to the protection circuit board (621) of the battery (620). The processor (611) can supply power to the protection circuit board (621) to prevent the occurrence of problems related to the charging or discharging of the battery (620).

[0115] Referring to FIG. 6, in operation 643, the processor (611) can supply power to the magnetic sensor (630) placed on the protection circuit board (621) through the power management circuit (612). In operation 644, the magnetic sensor (630) can be connected to the processor (611) itself and can directly transmit a sensing signal (e.g., sensing-related information by the magnetic sensor (630)) to the processor (611). In some cases, the processing of operation 644 may be handled by the power management circuit (612).

[0116] According to one embodiment, the processor (611) can supply power to a magnetic sensor (630) in connection with a charging function of the battery (620) (e.g., MPP charging, or EPP charging), and can detect a magnetic member (e.g., an annular magnet, or the magnetic member (520) of FIG. 4) placed on the rear of the electronic device (601) based on the magnetic sensor (630). For example, if the magnetic member (520) is detected on the rear of the electronic device (601), the processor (611) can perform a charging function based on the MPP charging method, and if the magnetic member (520) is not detected on the rear of the electronic device (601), the processor (611) can perform a charging function based on the EPP charging method.

[0117] According to one embodiment, the MPP charging method may require alignment between an induction coil (e.g., the induction coil (530) of FIG. 4, or a receiving coil) and a transmitting coil of an external charging device. The external charging device may be attached to the rear of an electronic device (601) by means of a magnetic member (520), and when the external charging device is attached to the rear of the electronic device (601), the transmitting coil of the external charging device and the receiving coil of the electronic device (601) (e.g., the induction coil (530)) may be arranged in a form that overlaps each other. According to one embodiment, a processor (611) may determine the presence of the magnetic member (520) based on a magnetic sensor (630), and if the magnetic member (520) is present, it may perform a charging function based on the MPP charging method.

[0118] FIG. 7a is an exemplary diagram illustrating the position where a magnetic sensor is placed on the rear of an electronic device according to one embodiment of the present disclosure. FIG. 7b is an internal cross-sectional view of an electronic device cut along the reference line of FIG. 7a according to one embodiment of the present disclosure.

[0119] The electronic device (400) of FIGS. 7a and 7b may be at least partially similar to the electronic device (400) of FIG. 4, or may include other embodiments of the electronic device (400).

[0120] Referring to FIG. 7a, the rear view of the electronic device (400) (e.g., the second side (210B) of FIG. 2b) is viewed with the rear cover of the electronic device (400) (e.g., the rear plate (211) of FIG. 2b) removed. FIG. 7a may be substantially the same configuration as FIG. 4.

[0121] Referring to FIG. 7a, a reference line (710) is shown crossing a protection circuit board (510) (e.g., a second printed circuit board) and a magnetic sensor (511) (e.g., at least one magnetic sensor) placed on the protection circuit board (510). FIG. 7b shows an internal cross-sectional view cut along the reference line (710) of FIG. 7a.

[0122] Referring to FIG. 7b, the electronic device (400) may be arranged in a stacked form with multiple substrates in an internal space. For example, on the front of the electronic device (400) (e.g., the first surface (210A) of FIG. 2a), a display (702) (e.g., the display (201) of FIG. 2a) and a front glass (701) arranged to cover the display (702) may be stacked. On the rear of the electronic device (400) (e.g., the second surface (210B) of FIG. 2b), an induction coil (705) for charging a battery (e.g., the battery (450) of FIG. 7a) (e.g., the induction coil (530) of FIG. 4, a wireless charging coil) and a rear cover (706) arranged to cover the induction coil (705) (e.g., the rear cover (380) of FIG. 3, the rear plate (211) of FIG. 2, or a second plate) may be stacked. According to one embodiment, a protection circuit board (703) (e.g., the protection circuit board (510) of FIG. 7a, or a second printed circuit board) for controlling functions for the battery (450) (e.g., over-discharge protection function, over-charge protection function, over-current cutoff function, and / or short-circuit protection function) may be disposed in the internal space between the front glass (701) and the rear cover (706). According to one embodiment, at least one magnetic sensor (704) may be disposed on the protection circuit board (703).

[0123] Referring to FIG. 7b, the magnetic sensor (704) (e.g., the magnetic sensor (511) of FIG. 7a) may be positioned along a direction (e.g., -z-axis direction) toward the rear cover (706) centered on the protection circuit board (703) (e.g., the second printed circuit board). The magnetic sensor (704) may be positioned on the protection circuit board (510) (e.g., the second printed circuit board) rather than on the first board (e.g., the first board (430a) of FIG. 7a, the first printed circuit board). For example, the magnetic sensor (704) may detect a magnetic member (e.g., the magnetic member (520) of FIG. 4, a magnet, or an annular magnet) positioned on the rear of the electronic device (400). The magnetic sensor (704) may be positioned along a direction toward the rear cover (706) centered on the protection circuit board (703) (e.g., -z-axis direction) to enhance the detection performance of the magnetic member. According to one embodiment, the positioning structure and positioning direction of the magnetic sensor (704) are not specified and may be changed to fit the internal space of the electronic device (400). According to another embodiment, the magnetic sensor (704) may be positioned along a direction toward the front glass (701) centered on the protection circuit board (703) (e.g., z-axis direction).

[0124] According to one embodiment, the magnetic sensor (704) may be placed at least partially on a flat protective circuit board (703) and may be utilized to detect a magnetic member (e.g., magnetic member (520) of FIG. 4, a magnet, or an annular magnet) placed on the rear of an electronic device (400).

[0125] FIG. 8a is an internal cross-sectional view of an electronic device when the rear cover of the electronic device according to one embodiment of the present disclosure includes an annular magnet. FIG. 8b is an internal cross-sectional view of an electronic device when the outer case, which is coupled in a manner that contacts the rear surface of the electronic device from the outside according to one embodiment of the present disclosure, includes an annular magnet.

[0126] The electronic device (400) of FIGS. 8a and 8b may be at least partially similar to the electronic device (400) of FIG. 4, or may include other embodiments of the electronic device (400).

[0127] Referring to FIG. 8a, the rear cover (707) of the electronic device (400) (e.g., the rear plate (211) of FIG. 2b) may at least partially contain a magnetic element (711) (e.g., the magnetic element (520) of FIG. 4, a magnet, or an annular magnet). According to one embodiment, a magnetic sensor (704) placed in the internal space of the electronic device (400) may be positioned to detect the magnetic element (711) contained in the rear cover (707). For example, the position of the magnetic sensor (704) may be determined based on the area where the magnetic element (711) and the protective circuit board (703) overlap when viewed from the rear of the electronic device (400) (e.g., when viewed from the outside in the z-axis direction).

[0128] Referring to FIG. 8b, an outer case (708) (e.g., accessory cover) that is at least partially coupled to a rear cover (706) (e.g., rear plate (211) of FIG. 2b) of an electronic device (400) may include a magnetic member (712) (e.g., magnetic member (520) of FIG. 4, a magnet, or an annular magnet). For example, the electronic device (400) may be structured such that the outer case (708) is at least partially coupled along the z-axis direction from the outside. According to one embodiment, a magnetic sensor (704) placed in the internal space of the electronic device (400) may be positioned to detect the magnetic member (712) contained in the outer case (708). For example, when viewed from the rear of the electronic device (400), (e.g., when viewed from the outside in the z-axis direction), the placement location of the magnetic sensor (704) can be determined based on the area where the magnetic member (712) and the protection circuit board (703) overlap.

[0129] According to one embodiment, in performing a charging function for a battery (450), the electronic device (400) requires alignment between the transmitting coil of an external charging device and the induction coil (705) (e.g., receiving coil) included in the electronic device (400). When the external charging device is placed on the rear of the electronic device (400), the rear cover (707) or the external case (708) may include magnetic members (711, 712) so that the transmitting coil of the external charging device is accurately placed at a predetermined position. For example, when viewed from the rear of the electronic device (400) (e.g., when viewed from the outside toward the z-axis direction), the magnetic members (711, 712) may be implemented in an annular shape that at least partially wraps the induction coil (705) along the outer side of the induction coil (705). When viewed from the rear of the electronic device (400), the magnetic members (711, 712) may be implemented in at least a partial annular shape without overlapping with the induction coil (705). For example, an external charging device may be positioned to be attached to the rear of the electronic device (400) based on the magnetism of the magnetic members (711, 712).

[0130] According to one embodiment, when an external charging device is attached to the rear of an electronic device (400), the transmitting coil of the external charging device and the magnetic members (711, 712) of the electronic device (400) can be aligned at a set position. For example, when viewed from the rear of the electronic device (400), the transmitting coil of the external charging device and the magnetic members (711, 712) of the electronic device (400) can be aligned in a form that overlaps each other.

[0131] According to one embodiment, the electronic device (400) can use a magnetic sensor (704) to detect a magnetic member (711) included in a rear cover (707) or a magnetic member (712) included in an outer case (708), and in response to the detection of the magnetic member, can perform a charging function based on an MPP charging method. The battery (450) can be charged by an external charging device based on an MPP charging method.

For example, the display (805) and the front glass (806) may be stacked in a form supported by a support member (804) (e.g., a bracket or a support structure). On the rear surface (e.g., the second surface (210B) of FIG. 2b) of the electronic device (400), an induction coil sheet (802) (e.g., a wireless charging coil sheet) containing an induction coil (e.g., the induction coil (530) of FIG. 4, or a wireless charging coil) for charging a battery (813) (e.g., the battery (450) of FIG. 7a)) and a rear cover (801) (e.g., the rear cover (380) of FIG. 3, the rear plate (211) of FIG. 2, or a second plate) disposed to cover the induction coil sheet (802) may be laminated. According to one embodiment, a protection circuit board (812) (e.g., the protection circuit board (510) of FIG. 7a, or a second printed circuit board) for controlling functions of the battery (813) (e.g., over-discharge protection function, over-charge protection function, over-current cutoff function, and / or short-circuit protection function) may be disposed in the internal space (4001) between the support member (804) and the rear cover (801). The protection circuit board (812) may be electrically connected to the battery (813) using a connecting member (814) and may control the functions of the battery (813) in relation to the charging or discharging of the battery (813). According to one embodiment, a magnetic sensor (811) (e.g., the magnetic sensor (511) of FIG. 4) may be disposed on the protection circuit board (812).

[0135] Referring to FIG. 9a, the electronic device (400) may implement a recess space based on a support member (804) for placing a battery (813) and a protection circuit board (812) electrically connected to the battery (813).

For example, the recess space may be implemented in a form in which a bracket wall, which is part of a bracket, at least partially surrounds it.

[0136] Referring to FIG. 9a, the magnetic sensor (811) may be positioned along a direction (e.g., -z-axis direction) toward the rear cover (801) centered on the protection circuit board (812). For example, the magnetic sensor (811) may detect a magnetic member (822) (e.g., magnetic member (520) of FIG. 4, a magnet, or an annular magnet) positioned on the rear of the electronic device (400). To enhance the detection performance of the magnetic member (822), the magnetic sensor (811) may be positioned along a direction (e.g., -z-axis direction) toward the rear cover (801) centered on the protection circuit board (812). According to one embodiment, the positioning structure and positioning direction of the magnetic sensor (801) are not specified and may be changed to fit the internal space (4001) of the electronic device (400).

For example, the electronic device (400) may be structured such that the outer case (821) is at least partially coupled along the z-axis direction from the outside. According to one embodiment, a magnetic sensor (811) placed in an internal space (4001) of the electronic device (400) may be positioned to detect the magnetic member (822) contained in the outer case (821). For example, when viewed from the rear of the electronic device (400), (e.g., when viewed from the outside in the z-axis direction), the placement location of the magnetic sensor (811) can be determined based on the area where the magnetic member (822) and the protection circuit board (812) overlap.

For example, the magnetic sensor (811) may detect the magnetic member (822) contained in the outer case (821) through the opening (823). By forming the opening (823) in the induction coil sheet (802), the sensing performance of the magnetic sensor (811) may be improved.

[0139] Referring to FIG. 9b, the electronic device (400) may include a protective member (824) (e.g., a resin filler such as Flax) that at least partially surrounds the magnetic sensor (811) for the protection of the magnetic sensor (811).
