Description

Electronic device including a transmitting coil

[0001] The present disclosure relates to an electronic device including a transmitting coil.

[0002] An electronic device can transmit power to an external electronic device, including a transmitting coil, placed on the electronic device. The external electronic device may be a wearable device (e.g., a smart ring-type electronic device). The external electronic device can receive power from the electronic device and charge it with the power needed to operate it.

[0003] An electronic device may include a mounting portion for mounting an external electronic device and a transmitter for transmitting power to the external electronic device. The external electronic device may be positioned on one side of the mounting portion of the electronic device. The transmitter portion of the electronic device may extend so as to protrude from one side of the mounting portion. When the external electronic device is mounted on the electronic device, the transmitter portion of the electronic device may be inserted into an opening of the external electronic device.

[0004] The above information may be provided as background information to aid in understanding the present disclosure. None of the above is claimed to be prior art related to the present disclosure, nor can it be used to determine prior art.

[0005] The external electronic device may be formed to have various sizes to correspond to the user's body size (e.g., the thickness of a finger).

[0006] If each electronic device is manufactured with different sized transmitters to correspond to external electronic devices of different sizes, the manufacturing cost of the electronic device may increase.

[0007] In order to transmit power to external electronic devices having different sizes, each electronic device having a size corresponding to the external electronic device is required, which may reduce the convenience of the user using the external electronic device.

[0008] When an external electronic device is placed in an electronic device whose size does not correspond to that of the external electronic device, the distance between the coil of the external electronic device and the coil of the electronic device may increase, which may reduce the power charging efficiency of the external electronic device.

[0009] An electronic device according to one embodiment of the present disclosure may include a mounting portion and a transmitter portion that protrudes and extends from the mounting portion. The transmitter portion according to one embodiment may include a transmitter portion housing that forms an exterior of the transmitter portion and a transmitter coil that is disposed inside the transmitter portion housing and transmits power to an external electronic device. The transmitter portion housing according to one embodiment may include a first region that extends and has a first radius of curvature, in which the transmitter coil is disposed inside, and a second region that extends from the first region and has a second radius of curvature that is smaller than the first radius of curvature.

[0010] A power charging system for an electronic device according to one embodiment of the present disclosure may include a housing formed in a ring shape including an insertion opening, and a first electronic device disposed inside the housing and including a coil for transmitting and receiving power. The power charging system for an electronic device according to one embodiment may include a second electronic device in which the first electronic device is disposed and which transmits power to the first electronic device. In one embodiment, the second electronic device may include a mounting portion that supports the first electronic device on one side, and a transmitting portion that protrudes from the mounting portion and is inserted into the insertion opening of the first electronic device. The transmitting portion of the second electronic device may include a transmitting portion housing that forms an outer appearance of the transmitting portion, and a transmitting coil disposed inside the transmitting portion housing and for transmitting power to the first electronic device. The transmitting portion housing of the second electronic device may include a first region in which the transmitting coil is disposed inside and extends and has a first radius of curvature, and a second region in which the second region extends from the first region and has a second radius of curvature smaller than the first radius of curvature.

[0011] An electronic device according to one embodiment of the present disclosure may include a housing extending in a ring shape, a battery disposed inside the housing, a printed circuit board disposed inside the housing and electrically connected to the battery, a coil disposed inside the housing and for transmitting and receiving power, and a magnetic material disposed between a side of the housing and the battery.

[0012] An electronic device according to one embodiment of the present disclosure includes a transmitter housing formed to have a double radius of curvature, so that external electronic devices of various sizes can be placed therein.

[0013] Since one electronic device according to one embodiment of the present disclosure can correspond to external electronic devices of various sizes, the manufacturing cost for individually manufacturing each electronic device corresponding to the external electronic device can be reduced.

[0014] An electronic device according to one embodiment of the present disclosure can be placed in contact with external electronic devices of various sizes, and thus can maintain a charging efficiency above a set standard regardless of the size of the external electronic device.

[0015] An electronic device according to one embodiment of the present disclosure can maintain a coupling coefficient between a coil of the electronic device and a coil of the external electronic device at a predetermined value or higher, since external electronic devices of various sizes can be contacted and placed therein.

[0016] An electronic device according to one embodiment of the present disclosure can place an external electronic device at a predetermined position on the electronic device using a magnetic material.

[0017] An electronic device according to one embodiment of the present disclosure can prevent or reduce magnetic field lines generated from a magnetic material from affecting a transmission coil of the electronic device.

[0073] In one embodiment, the transmitter (222) may include a transmitter housing (2221), a transmitter coil (2222), and / or a transmitter magnet (2223).

[0074] In one embodiment, the transmitter housing (2221) may form the exterior of the transmitter (222).

[0075] In one embodiment, the transmitter housing (2221) may be extended to protrude away from one surface of the mounting housing (2211). For example, the transmitter housing (2221) may be formed integrally with the mounting housing (2211) and may refer to a housing portion where the transmitter (222) is located.

[0076] In one embodiment, the width of the transmitter housing (2221) may be formed smaller than the width of the mounting housing (2211).

[0077] In one embodiment, the transmitter housing (2221) may be formed in a shape corresponding to the insertion opening (215) of the first electronic device (210). For example, if the insertion opening (215) has a circular shape, the transmitter housing (2221) may have a cylindrical shape having a circular cross-section.

[0078] In one embodiment, when the first electronic device (210) is positioned in the second electronic device (220), the transmitter housing (2221) can be inserted into the insertion opening (215) of the first electronic device (210). When the transmitter housing (2221) is inserted into the insertion opening (215) of the first electronic device (210), the first electronic device (210) can be maintained in a set position in the second electronic device (220).

[0079] In one embodiment, the transmitter coil (2222) and the transmitter magnet (2223) may be placed inside the transmitter housing (2221).

[0080] In one embodiment, the transmitting coil (2222) may serve to transmit power to a device located outside the second electronic device (220). For example, when the first electronic device (210) is located in the second electronic device (220), the second electronic device (220) may transmit power to the first electronic device (210) using the transmitting coil (2222).

[0081] Referring to FIG. 2B, when the first electronic device (210) is positioned on the second electronic device (220), the coil (212) of the first electronic device (210) is positioned corresponding to the transmitting coil (2222) of the second electronic device (220) and can receive power from the transmitting coil (2222).

[0082] In one embodiment, when the first electronic device (210) is positioned on the second electronic device (220), the transmitting magnetic body (2223) of the transmitting unit (222) may be positioned corresponding to the first side magnetic body (2131) of the first electronic device (210). For example, when the first electronic device (210) is positioned on the second electronic device (220), the transmitting magnetic body (2223) of the transmitting unit (222) may face the first side magnetic body (2131) of the first electronic device (210) with the transmitting unit housing (2221) and the housing (211) interposed therebetween.

[0083] In one embodiment, when the first electronic device (210) is positioned on the second electronic device (220), the first electronic device (210) can be maintained at a set position through an attractive force acting between the magnetic body (213) of the first electronic device (210) and the magnetic body (2212, 2223) of the second electronic device (220).

[0084] FIG. 3a, FIG. 3b, and FIG. 3c are drawings showing a transmitter (300) and an external electronic device (400) according to one embodiment of the present disclosure.

[0085] Fig. 3a is a drawing showing a transmitter (300) in which a transmitter magnetic body (330) is positioned in a second region (312). Fig. 3b is a drawing showing a transmitter (300) in which a transmitter magnetic body (330) is positioned in a first region (311). Fig. 3c is a drawing showing an external electronic device (400) having two radii of curvature (R1, R2).

[0086] The transmitter (300) of FIGS. 3a and 3b may refer to the transmitter (222) of FIGS. 2a and 2b, or may include at least some of the components of the transmitter (222).

[0087] The external electronic device (400) of FIGS. 3a, 3b, and 3c may refer to the first electronic device (210) of FIGS. 2a and 2b, or may include at least some of the components of the first electronic device (210).

[0088] In one embodiment, the transmitter (300) may include a transmitter housing (310), a transmitter coil (320), and / or a transmitter magnet (330).

[0089] In one embodiment, the transmitter housing (310) may form the exterior of the transmitter (300). Other components of the transmitter (300), such as the transmitter coil (320), may be positioned inside the transmitter housing (310).

[0090] In one embodiment, the transmitter housing (310) may include a first region (311) and / or a second region (312).

[0091] In one embodiment, the first region (311) and the second region (312) may extend with different radii of curvature.

[0092] In one embodiment, the first region (311) may be an area extending with a perimeter having a first radius of curvature (R1). For example, the perimeter of the first region (311) may extend with a first radius of curvature (R1) based on the first center (C1).

[0093] In one embodiment, the second region (312) may be an area extending with a perimeter having a second radius of curvature (R2). For example, the perimeter of the second region (312) may extend with a second radius of curvature (R2) based on the second center (C2).

[0094] In one embodiment, the first radius of curvature (R1) may be longer than the second radius of curvature (R2). For example, the first radius of curvature (R1) may have a length of approximately 15 to 17 mm. The second radius of curvature (R2) may have a length of approximately 14 to 15 mm. However, the present invention is not limited thereto.

[0095] In one embodiment, the length by which the second region (312) extends along the perimeter of the transmitter housing (310) may be longer than the length by which the first region (311) extends along the perimeter of the transmitter housing (310).

[0096] In one embodiment, the transmitting coil (320) may serve to transmit power to an external device. For example, the transmitting unit (300) may transmit power to an external electronic device (400) using the transmitting coil (320).

[0097] In one embodiment, the transmitter coil (320) may be placed in the first region (311) of the transmitter housing (310). In one embodiment, the perimeter of the first region (311) of the transmitter housing (310) may be formed longer than the transmitter coil (320).

[0098] In one embodiment, the transmitter magnetic body (330) may include a first transmitter magnetic body (331) and / or a second transmitter magnetic body (332). In one embodiment, the transmitter magnetic body (330) of FIGS. 3A and 3B may refer to the transmitter magnetic body (2223) of FIG. 2A.

[0099] In one embodiment, the radius of curvature around the transmitter housing (310) may be formed differently based on the boundary between the first region (311) and the second region (312). In one embodiment, the transmitter magnetic body (330) may be positioned so that at least a portion thereof is located at the boundary between the first region (311) and the second region (312).

[0100] Referring to FIG. 3A, a transmitter magnetic body (330) according to one embodiment may be disposed in a second region (312) of a transmitter housing (310). In one embodiment, the transmitter magnetic body (330) may be disposed to face the peripheral surface of the transmitter housing (310). In one embodiment, a first transmitter magnetic body (331) may be disposed to face the peripheral surface of the transmitter housing (310) on one side of the first region (311), and a second transmitter magnetic body (332) may be disposed to face the peripheral surface of the transmitter housing (310) on the other side of the first region (311).

[0101] Referring to FIG. 3B, a transmitter magnetic body (330) according to one embodiment may be placed in a first region (311) of a transmitter housing (310). In one embodiment, the first transmitter magnetic body (331) and the second transmitter magnetic body (332) may be placed in a part of the first region (311) adjacent to the second region (312).

[0102] In one embodiment, the transmitting coil (320) may be positioned at a location that does not overlap with the transmitting magnetic body (330). For example, the transmitting coil (320) may be positioned between the first transmitting magnetic body (331) and the second transmitting magnetic body (332).

[0103] Since the transmitting coil (320) according to one embodiment is positioned so as not to overlap with the transmitting magnetic body (330), the influence of the transmitting coil (320) on the magnetic field lines generated by the transmitting magnetic body (330) can be prevented or reduced.

[0104] In one embodiment, the external electronic device (400) may include a circular shape having a predetermined radius. For example, the external electronic device (400) may be formed to have a circular shape having an inner side having a second radius of curvature (R2).

[0105] In one embodiment, the external electronic device (400) may include an external magnet (410).

[0106] In one embodiment, the external magnet (410) may include a first external magnet (411) and / or a second external magnet (412). In one embodiment, the external magnet (410) of FIGS. 3A and 3B may refer to the magnet (213) of FIG. 2A.

[0107] In one embodiment, when the external electronic device (400) is positioned in the transmitter (300), the external magnetic body (410) may be positioned corresponding to the transmitter magnetic body (330). For example, the first external magnetic body (411) may be positioned corresponding to the first transmitter magnetic body (331). The second external magnetic body (412) may be positioned corresponding to the second transmitter magnetic body (332).

[0108] Referring to FIG. 3a, when the transmitter magnetic body (330) is placed in the second region (312) of the transmitter housing (310), the external magnetic body (410) of the external electronic device (400) can be placed at a position corresponding to the transmitter magnetic body (330) located in the second region (312).

[0109] Referring to FIG. 3b, when the transmitter magnetic body (330) is placed in the first region (311) of the transmitter housing (310), the external magnetic body (410) of the external electronic device (400) can be placed at a position corresponding to the transmitter magnetic body (330) located in the second region (311).

[0110] In one embodiment, an attractive force may be applied between the external magnetic body (410) and the transmitter magnetic body (330). For example, when the external electronic device (400) is positioned on the transmitter (300), the magnetic body (330) and the external magnetic body (410) may have opposite poles facing each other, so that an attractive force may be generated between the magnetic body (330) and the external magnetic body (410).

[0111] In one embodiment, when the external electronic device (400) is positioned on the transmitter (300), the external electronic device (400) may be positioned at a predetermined position by utilizing the attractive force acting between the external magnetic body (410) and the transmitter magnetic body (330). For example, the attractive force acting between the external magnetic body (410) and the transmitter magnetic body (330) may cause the transmitting coil (320) of the transmitter (300) to face the coil (e.g., 212, see FIG. 2A) of the external electronic device (400) with the transmitter housing (310) therebetween. In one embodiment, power may be transmitted between the transmitter (400) and the external electronic device (400) through the transmitting coil (320) of the transmitter (300) and the coil (e.g., 212, see FIG. 2A) of the external electronic device (400).

[0112] In one embodiment, when the external electronic device (400) is positioned in the transmitter (300), the second region (312) of the transmitter housing (310) may come into contact with the external electronic device (400). For example, the inner surface of the external electronic device (400) and the perimeter of the second region (312) of the transmitter housing (310) may extend with a second radius of curvature (R2), so that the inner surface of the external electronic device (400) and the perimeter of the second region (312) of the transmitter housing (310) may come into contact.

[0113] In one embodiment, when an external electronic device (400) is positioned on the transmitter (300), the second area (312) of the transmitter housing (310) may come into contact with the external electronic device (400) and support the external electronic device (400). Since the second area (312) of the transmitter housing (310) comes into contact with the external electronic device (400), movement of the external electronic device (400) due to an external force is reduced, and the external electronic device (400) may easily maintain a set position.

[0114] In one embodiment, when the external electronic device (400) is positioned in the transmitter (300), the first region (311) of the transmitter housing (310) may be spaced apart from the external electronic device (400). Referring to FIG. 3A, the first region (311) and the inner surface of the external electronic device (400) may be spaced apart by a distance less than or equal to a separation distance (G). Since the first region (311) of the transmitter housing (310) has a first radius of curvature (R1) and the inner surface of the external electronic device (400) has a second radius of curvature (R2), the first region (311) of the transmitter housing (310) may be spaced apart from the external electronic device (400) without coming into contact with each other.

[0115] In one embodiment, the separation distance (G) may be formed to be less than or equal to a predetermined length. As the separation distance (G) increases, the coupling coefficient between the transmission coil (320) of the transmitter (300) and the coil (e.g., 212, see FIG. 2A) of the external electronic device (400) may decrease. The separation distance (G) may be formed to be less than or equal to a predetermined length so that the coupling coefficient between the transmission coil (320) of the transmitter (300) and the coil (e.g., 212, see FIG. 2A) of the external electronic device (400) is approximately 0.2 or greater.

[0116] In one embodiment, as the separation distance (G) increases, the power charging efficiency of the external electronic device (400) may decrease. In one embodiment, the separation distance (G) may be formed to be less than a predetermined length so that the power charging efficiency of the external electronic device (400) is approximately 60% or more.

[0117] Referring to FIG. 3C, an external electronic device (400) according to one embodiment may have two different radii of curvature (R1, R2). In one embodiment, a portion of the external electronic device (400) may have a first radius of curvature (R1), and a remaining portion of the external electronic device (400) may have a second radius of curvature (R2). For example, a portion of the external electronic device (400) facing the first portion (311) of the transmitter housing (310) may extend with a first radius of curvature (R1), and a remaining portion of the external electronic device (400) may extend with a second radius of curvature (R2) that is smaller than the first radius of curvature (R1).

[0118] In one embodiment, when an external electronic device (400) having a first radius of curvature (R1) and a second radius of curvature (R2) is positioned in the transmitter (300), an inner surface of the external electronic device (400) (e.g., a surface of the external electronic device (400) facing the transmitter housing (310)) and a perimeter of the transmitter housing (310) may be brought into contact with each other. Alternatively, when an external electronic device (400) having a first radius of curvature (R1) and a second radius of curvature (R2) is positioned in the transmitter (300), a distance between the inner surface of the external electronic device (400) and the perimeter of the transmitter housing (310) may be reduced to a predetermined length or less.

[0119] FIG. 4a, FIG. 4b, and FIG. 4c are diagrams showing a transmitter (300) and an external electronic device (500) according to one embodiment of the present disclosure.

[0120] Fig. 4a is a drawing showing a transmitter (300) in which a transmitter magnetic body (330) is positioned in a second region (312). Fig. 4b is a drawing showing a transmitter (300) in which a transmitter magnetic body (330) is positioned in a first region (311). Fig. 4c is a drawing showing an external electronic device (500) having two radii of curvature (R1, R3).

[0121] The external electronic device (500) of FIGS. 4A, 4B, and 4C may refer to the first electronic device (210) of FIGS. 2A and 2B, or may include at least some of the components of the first electronic device (210).

[0122] The external electronic device (500) of FIGS. 4A, 4B, and 4C may be a device having a larger radius than the external electronic device (400) of FIGS. 3A and 3B. For example, the external electronic device (400) of FIGS. 3A and 3B may be extended so that the inner surface has a second radius of curvature (R2), and the external electronic device (500) of FIGS. 4A and 4B may be extended so that the inner surface has a first radius of curvature (R1) and / or a third radius of curvature (R3) that is longer than the second radius of curvature (R2).

[0123] In one embodiment, the external electronic device (500) may include a first external magnetic body (511) and / or a second external magnetic body (512). In one embodiment, the external magnetic body (510) of FIGS. 4A and 4B may refer to the magnetic body (213) of FIG. 2A.

[0124] In one embodiment, when the external electronic device (500) is positioned in the transmitter (300), the external magnetic body (510) may be positioned corresponding to the transmitter magnetic body (330). For example, the first external magnetic body (511) may be positioned corresponding to the first transmitter magnetic body (331). The second external magnetic body (512) may be positioned corresponding to the second transmitter magnetic body (332).

[0125] Referring to FIG. 4a, when the transmitter magnetic body (330) is placed in the second region (312) of the transmitter housing (310), the external magnetic body (510) of the external electronic device (500) can be placed at a position corresponding to the transmitter magnetic body (330) located in the second region (312).

[0126] Referring to FIG. 4b, when the transmitter magnetic body (330) is placed in the first region (311) of the transmitter housing (310), the external magnetic body (510) of the external electronic device (500) can be placed at a position corresponding to the transmitter magnetic body (330) located in the first region (311).

[0127] In one embodiment, an attractive force may be applied between the external magnetic body (510) and the transmitter magnetic body (330). For example, when the external electronic device (500) is positioned in the transmitter (300), the magnetic body (330) and the external magnetic body (510) may have opposite poles facing each other, so that an attractive force may be generated between the magnetic body (330) and the external magnetic body (510).

[0128] In one embodiment, when an external electronic device (500) is positioned on the transmitter (300), the external electronic device (500) may be positioned at a predetermined position on the transmitter (300) by utilizing an attractive force acting (or occurring) between the external magnetic body (510) and the transmitter magnetic body (330). For example, the attractive force acting between the external magnetic body (510) and the transmitter magnetic body (330) may cause the transmitting coil (320) of the transmitter (300) to face the coil (e.g., 212, see FIG. 2A) of the external electronic device (500) with the transmitter housing (310) interposed therebetween.

[0129] In one embodiment, power may be transferred between the transmitter (300) and the external electronic device (500) via a transmitting coil (320) of the transmitter (300) and a coil (e.g., 212, see FIG. 2A) of the external electronic device (500).

[0130] In one embodiment, when the external electronic device (500) is positioned in the transmitter (300), the first region (311) of the transmitter housing (310) may come into contact with the external electronic device (500). For example, the inner surface of the external electronic device (500) and the perimeter of the first region (311) of the transmitter housing (310) each extend with a first radius of curvature (R1), so that the inner surface of the external electronic device (500) and the perimeter of the first region (311) of the transmitter housing (310) may come into contact.

[0131] Referring to FIG. 4C, an external electronic device (500) according to one embodiment may have two different radii of curvature (R1, R3). In one embodiment, a portion of the external electronic device (500) may have a first radius of curvature (R1), and a remaining portion of the external electronic device (500) may have a third radius of curvature (R3) with respect to a third center (C3). The third radius of curvature (R3) may be longer than the first radius of curvature (R1). For example, a portion of the external electronic device (500) facing the first portion (311) of the transmitter housing (310) may be extended and have the first radius of curvature (R1), and a remaining portion of the external electronic device (500) may be extended and have the third radius of curvature (R3).

[0132] In one embodiment, the third radius of curvature (R3) may be shorter than the first radius of curvature (R1). In one embodiment, when the second region (312) of the transmitter housing (310) has the second radius of curvature (R2), the third radius of curvature (R3) may be longer than the second radius of curvature (R2). In one embodiment, the third radius of curvature (R3) may be shorter than the first radius of curvature (R1) and longer than the second radius of curvature (R2).

[0133] In one embodiment, when an external electronic device (500) having a first radius of curvature (R1) and a third radius of curvature (R3) is positioned in the transmitter (300), an inner surface of the external electronic device (500) facing the first area (311) of the transmitter housing (310) (e.g., a surface of the external electronic device (500) facing the transmitter housing (310) may be in contact with the perimeter of the first area (311) of the transmitter housing (310).

[0134] Referring to FIGS. 4A, 4B, and 4C, when an external electronic device (500) according to one embodiment is positioned on a transmitter (300), a first region (311) of a transmitter housing (310) may come into contact with the external electronic device (500) and support the external electronic device (500). Since the first region (311) of the transmitter housing (310) comes into contact with the external electronic device (500), movement of the external electronic device (500) due to an external force is reduced, and the external electronic device (500) may easily maintain a set position.

[0135] In one embodiment, the transmitter (300) extends such that the first region (311) and the second region (312) of the transmitter housing (310) have different radii of curvature, so that electronic devices (400, 500) having different sizes can be positioned on the transmitter (300). For example, referring to FIGS. 4A and 5 , the external electronic device (400) of FIG. 3A having a second radius of curvature (R2) and the external electronic device (500) of FIG. 4A having a first radius of curvature (R1) can be brought into contact with and mounted on the transmitter (300). Since the transmitter (300) according to one embodiment can accommodate electronic devices (400, 500) having different sizes, a separate mounting device for mounting the electronic devices (400, 500) having different sizes may not be required.

[0136] In one embodiment, the size of the transmitter magnetic body (330) may be formed to be larger than the size of the external magnetic body (510). For example, if it is difficult to form a large space in which the external magnetic body (510) can be placed in the external electronic device (500), the size of the transmitter magnetic body (330) may be formed to be relatively large, so that an attractive force greater than a predetermined size may be generated between the transmitter magnetic body (330) and the external magnetic body (510).

[0137] Although the external electronic device (500) having the first radius of curvature (R1) at least in a portion of FIGS. 4A, 4B, and 4C is illustrated, the radius of curvature of the external electronic device (500) may not be limited thereto. For example, the external electronic device (500) may have a longer radius of curvature than the first radius of curvature (R1) in a portion corresponding to the first region (311) of the transmitter housing (310). In this case, the external electronic device (500) may be placed in contact with a portion of the first region (311) of the transmitter housing (310).

[0138] FIG. 5 is a drawing showing a third transmitting magnetic body (333) and a third external magnetic body (513) according to one embodiment of the present disclosure.

[0139] Referring to FIG. 5, a transmitter (300) according to one embodiment may include a third transmitter magnetic body (333).

[0140] In one embodiment, the third transmitter magnet (333) may be positioned inside the transmitter housing (310). For example, the third transmitter magnet (333) may be positioned in the second region (312) of the transmitter housing (310).

[0141] In one embodiment, the third transmitter magnet (333) may be positioned on the opposite side of the transmitter coil (320). For example, the third transmitter magnet (333) may be positioned so as to face a surface located in the opposite direction to the surface facing the transmitter coil (320) within the transmitter housing (310).

[0142] Referring to FIG. 5, an external electronic device (500) according to one embodiment may include a third external magnetic body (513).

[0143] In one embodiment, when an external electronic device (500) is positioned in the transmitter (300), the third external magnetic body (513) may be positioned corresponding to the third transmitter magnetic body (333).

[0144] In one embodiment, a repulsive force may be generated between the third transmitter magnetic body (333) and the third external magnetic body (513). For example, when an external electronic device (500) is positioned at the transmitter (300), the third transmitter magnetic body (333) and the third external magnetic body (513) may face each other with the same poles (e.g., N pole or S pole), so that a repulsive force may be generated between the third transmitter magnetic body (333) and the third external magnetic body (513).

[0145] In one embodiment, when the external electronic device (500) is positioned on the transmitter (300), the external electronic device (500) may be placed in contact with the first region (311) of the transmitter (300) due to a repulsive force generated between the third external magnetic body (513) and the third transmitter magnetic body (333). Since the external electronic device (500) is placed in contact with the first region (311) of the transmitter (300), movement of the external electronic device (500) due to an external force is reduced, and thus, the external electronic device (500) may easily maintain a set position on the transmitter (300).

[0146] Referring to FIGS. 4A and 5, when the external electronic device (500) is positioned on the transmitter (300), the first region (311) of the transmitter (300) and the inner surface of the external electronic device (500) are placed in contact with each other, so that the distance between the transmitting coil (320) of the transmitter (300) and the coil (e.g., 212, see FIG. 2A) of the external electronic device (500) can become shorter. Since the distance between the transmitting coil (320) of the transmitter (300) and the coil (e.g., 212, see FIG. 2A) of the external electronic device becomes shorter, the coupling coefficient between the transmitting coil (320) and the coil (e.g., 212, see FIG. 2A) can have a predetermined value or more. For example, the coupling coefficient between the transmitting coil (320) and the coil (e.g., 212, see FIG. 2A) can have a value of approximately 0.2 or more.

[0147] In one embodiment, the transmitter (300) may include all of a first transmitter magnetic body (331, see FIG. 3A), a second transmitter magnetic body (332, see FIG. 4A), and a third transmitter magnetic body (333). When the transmitter (300) includes all of a first transmitter magnetic body (331, see FIG. 4A), a second transmitter magnetic body (332, see FIG. 4A), and a third transmitter magnetic body (333), the external electronic device (500) and the transmitter (300) may be brought into close contact using both attractive and repulsive forces, making it easier for the external electronic device (500) to maintain a set position in the transmitter (300).

[0148] FIG. 6A and FIG. 6B are drawings showing a transmitting magnetic body (610, 630) and an external magnetic body (620, 640) according to one embodiment of the present disclosure.

[0151] In one embodiment, the transmitter magnetic body (610) and the external magnetic body (620) may be arranged so that their poles face each other. For example, referring to FIG. 6A, the N pole of the transmitter magnetic body (610) and the S pole of the external magnetic body (620) may be arranged so that they face each other.

[0152] In one embodiment, the transmitter magnet (610) and the external magnet (620) are arranged with different poles facing each other, so that an attractive force can be generated between the transmitter magnet (610) and the external magnet (620).

[0153] In one embodiment, an external electronic device (400, 500, see FIGS. 3A and 4A) can be placed at a predetermined position in the transmitter (300, see FIG. 3A) by using an attractive force generated between the transmitter magnetic body (610) and the external magnetic body (620). For example, the external electronic device (400, 500, see FIGS. 3A and 4A) can be placed so that a coil (212, see FIG. 2A) of the electronic device (400, 500, see FIGS. 3A and 4A) faces a transmitting coil (320, see FIG. 3A) of the transmitter (300, see FIG. 3A) with the transmitter housing (310, see FIG. 3A) interposed therebetween by using an attractive force generated between the transmitter magnetic body (610) and the external magnetic body (620).

[0154] The transmitting magnetic body (630) of FIG. 6b may refer to the transmitting magnetic body (330) of FIG. 3a. The external magnetic body (640) of FIG. 6b may refer to the external magnetic body (410) of FIG. 3a or the external magnetic body (510) of FIG. 5.

[0155] Referring to FIG. 6b, the transmitting magnetic body (630) and the external magnetic body (640) may be arranged so that their poles face each other. For example, the N pole of the transmitting magnetic body (630) and the S pole of the external magnetic body (640) may be arranged so that they face each other, and the S pole of the transmitting magnetic body (630) and the N pole of the external magnetic body (640) may be arranged so that they face each other.

[0156] In one embodiment, the transmitter magnet (630) and the external magnet (640) are arranged with different poles facing each other, so that an attractive force can be generated between the transmitter magnet (630) and the external magnet (640).

[0157] In one embodiment, an external electronic device (400, 500, see FIGS. 3A and 4A) can be placed at a predetermined position in the transmitter (300, see FIG. 3A) by the attractive force generated between the transmitter magnetic body (630) and the external magnetic body (640). For example, the electronic device (400, 500, see FIGS. 3A and 4A) can be placed so that the coil (212, see FIG. 2A) of the electronic device (400, 500, see FIGS. 3A and 4A) faces the transmitting coil (320, see FIG. 3A) of the transmitter (300, see FIG. 3A) with the transmitter housing (310, see FIG. 3A) interposed therebetween by the attractive force generated between the transmitter magnetic body (630) and the external magnetic body (640).

[0158] Referring to FIG. 6B, the transmitter magnetic body (630) according to one embodiment may be arranged so that the N pole and the S pole are positioned alternately. For example, the transmitter magnetic body (630) may be formed so that the N pole and the S pole are formed alternately along the longitudinal direction of the transmitter magnetic body (630) (e.g., the direction in which the transmitter magnetic body (630) is relatively elongated).

[0159] Referring to FIG. 6B, the external magnetic body (640) according to one embodiment may be arranged so that the N pole and the S pole are positioned alternately. For example, the external magnetic body (640) may be formed so that the N pole and the S pole are formed alternately along the longitudinal direction of the external magnetic body (640) (e.g., the direction in which the external magnetic body (640) is relatively elongated).

[0160] In one embodiment, as the N pole and S pole of the transmitting magnetic body (630) are alternately positioned along the longitudinal direction of the transmitting magnetic body (630), the spreading phenomenon of the magnetic field lines generated by the transmitting magnetic body (630) and the external magnetic body (640) can be reduced. As the spreading phenomenon of the magnetic field lines is reduced, the magnetic field lines can be prevented or reduced from affecting the transmitting coil (320, see FIG. 3A).

[0161] In one embodiment, the transmitter (300, see FIG. 3A) may include a guide member (650). Referring to FIG. 6B, the guide member (650) may be positioned in one direction of the transmitter magnetic body (630).

[0162] In one embodiment, the guide member (650) may be included in an external electronic device (e.g., 400, 500, see FIGS. 3A and 4A). The guide member (650) may be positioned in one direction of the external magnetic body (640) in the external electronic device (e.g., 400, 500, see FIGS. 3A and 4A). For example, the guide member (650) may be positioned in an opposite direction from the direction in which the external magnetic body (640) faces the transmitter magnetic body (630).

[0163] In one embodiment, the guide member (650) may include cold rolled steel plate (SPCC, steel plate cold commercial).

[0164] In one embodiment, the guide member (650) may serve to guide the magnetic force lines generated by the transmitting magnetic body (630) and the external magnetic body (640). By guiding the magnetic force lines by the guide member (650), the attractive force generated between the transmitting magnetic body (630) and the external magnetic body (640) may be enhanced.
