Description

Technical Field

[0001] Various embodiments of this disclosure relate to electronic devices and methods including flexible displays, and to electronic devices and methods capable of improving antenna efficiency. Background Technology

[0002] With the development of display technology, research and development of electronic devices with flexible displays are actively underway. Flexible displays can be folded, bent, rolled up, or unfolded. Electronic devices incorporating flexible displays can change the size of the screen visible to the user.

[0003] The electronic device may include at least one antenna for wireless communication with external electronic devices or for charging a battery. For example, the electronic device may use at least one antenna to perform near field communication (NFC), magnetically secure transmission (MST), or wireless charging. Summary of the Invention

[0004] Technical issues

[0005] Research and development of sliding electronic devices are actively underway, in which flexible displays are applied to electronic devices, and the display area of ​​the display is variable. In electronic devices, a portion of the flexible display can move in a sliding manner in conjunction with the sliding movement of a portion of the electronic device's housing.

[0006] The electronic device may have at least one coil provided therein as an antenna for short-range communication functions (e.g., wireless charging, magnetically secure transmission (MST) communication, and / or near-field communication (NFC)).

[0007] As the form of electronic devices changes, the center of the coil used for short-range communication may be located away from the center of the electronic device, thus reducing antenna efficiency. For example, while the center of the coil and the center of the electronic device can be arranged close to each other when the electronic device is in a closed state with part of the flexible display in the sliding-in state, the center of the coil and the center of the electronic device are spaced apart when the electronic device is in an open state with part of the flexible display in the sliding-out state. Therefore, the center of the coil is not aligned with the center of the coil of the antenna included in the external electronic device, thus reducing antenna efficiency.

[0008] Various embodiments of this disclosure can provide an electronic device that, even with changes in the form of the electronic device, can reduce the reduction in the efficiency of antennas used for short-range communication.

According to an embodiment, the receiver may be implemented separately from the speaker or as part of the speaker.

[0038] Display module 160 can visually provide information to the outside of electronic device 101 (e.g., to a user). Display module 160 may include, for example, a display, a holographic device, or a projector, and control circuitry for controlling a respective one of the display, holographic device, and projector. According to an embodiment, display module 160 may include touch circuitry adapted to detect touch or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of the force caused by touch.

[0039] The audio module 170 can convert sound into electrical signals and vice versa. According to an embodiment, the audio module 170 can obtain sound via the input module 150, or output sound via the sound output module 155 or headphones of an external electronic device (e.g., electronic device 102) that is directly (e.g., wired) or wirelessly connected to the electronic device 101.

[0040] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user state), and then generate an electrical signal or data value corresponding to the detected state. According to embodiments, sensor module 176 may include, for example, a gesture sensor, gyroscope sensor, atmospheric pressure sensor, magnetic sensor, accelerometer, grip sensor, proximity sensor, color sensor, infrared (IR) sensor, biometric sensor, temperature sensor, humidity sensor, or illuminance sensor.

[0047] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a cellular network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0048] Wireless communication module 192 can support 5G networks and next-generation communication technologies beyond 4G networks, such as New Radio (NR) access technologies. NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), or ultra-reliable low-latency communications (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. Wireless communication module 192 can support various requirements specified in electronic device 101, external electronic devices (e.g., electronic device 104), or network systems (e.g., second network 199). According to an embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or higher) for implementing eMBB, lost coverage (e.g., 164 dB or lower) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or lower for each of the downlink (DL) and uplink (UL), or 1 ms or lower round trip) for implementing URLLC.

[0049] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element made of conductive material or conductive patterns formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, for example, communication module 190 (e.g., wireless communication module 192) may select at least one antenna suitable for a communication scheme used in a communication network such as a first network 198 or a second network 199. Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as part of antenna module 197.

[0050] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., external electronic device). According to embodiments, antenna module 197 may include one or more antennas, and therefore, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected by, for example, communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and external electronic device via the selected at least one antenna.

[0051] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0052] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. Each of electronic device 102 and electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some operations that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, the one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, either with further processing or without further processing. For this purpose, technologies such as cloud computing, distributed computing, or client-server computing may be used.

[0059] Figure 2 This is a block diagram 200 illustrating a wireless communication module 192, a power management module 188, and an antenna module 197 of an electronic device 101 according to various embodiments. (Refer to...) Figure 2 The wireless communication module 192 may include a Magnetic Secure Transmission (MST) communication module 210 or a Near Field Communication (NFC) module 230, and the power management module 188 may include a wireless charging module 250. In this case, the antenna module 197 may include multiple antennas, including an MST antenna 297-1 connected to the MST communication module 210, an NFC antenna 297-3 connected to the NFC communication module 230, and a wireless charging antenna 297-5 connected to the wireless charging module 250. For ease of description, [the following is a more detailed description of the antenna module 192]. Figure 1 Components that are identical to those described are either briefly described or omitted from the description.

[0060] MST communication module 210 can receive signals containing control information or payment information (such as card information) from processor 120, generate a magnetic signal corresponding to the received signal, and then transmit the generated magnetic signal to external electronic device 102 (such as a point-of-sale (POS) device) via MST antenna 297-1. To generate the magnetic signal, according to an embodiment, MST communication module 210 may include a switching module (not shown) comprising one or more switches connected to MST antenna 297-1, and controlling the switching module to change the direction of the voltage or current supplied to MST antenna 297-1 based on the received signal. The change in voltage or current direction allows the direction of the magnetic signal (e.g., magnetic field) emitted from MST antenna 297-1 to change accordingly. If detected at external electronic device 102, the magnetic signal with its changed direction can cause an effect (e.g., waveform) similar to that generated when a magnetic card corresponding to card information associated with the received signal is swiped through the card reader of electronic device 102. According to an embodiment, for example, payment-related information and control signals received by electronic device 102 in the form of magnetic signals can be further transmitted to external server 108 (e.g., payment server) via network 199.

[0061] The NFC communication module 230 can obtain signals containing control information or payment information (such as card information) from the processor 120 and transmit the obtained signals to the external electronic device 102 via the NFC antenna 297-3. According to an embodiment, the NFC communication module 230 can receive such signals transmitted from the external electronic device 102 via the NFC antenna 297-3.

[0062] The wireless charging module 250 can wirelessly transmit power to an external electronic device 102 (e.g., a cellular phone or wearable device) via the wireless charging antenna 297-5, or wirelessly receive power from an external electronic device 102 (e.g., a wireless charging device). The wireless charging module 250 can support one or more of a variety of wireless charging schemes, including, for example, magnetic resonance schemes or magnetic induction schemes.

[0063] According to embodiments, some of the MST antenna 297-1, NFC antenna 297-3, or wireless charging antenna 297-5 may share at least a portion of their radiators. For example, the radiator of MST antenna 297-1 may be used as the radiator of NFC antenna 297-3 or wireless charging antenna 297-5, and vice versa. In this case, antenna module 197 may include a switching circuit (not shown) adapted to selectively connect (e.g., close) or disconnect (e.g., open) at least a portion of antennas 297-1, 297-3, or 297-5, for example, under the control of wireless communication module 192 (e.g., MST communication module 210 or NFC communication module 230) or power management module (e.g., wireless charging module 250). For example, when the electronic device 101 uses the wireless charging function, the NFC communication module 230 or the wireless charging module 250 can control the switching circuit to temporarily disconnect at least a portion of the radiator shared by the NFC antenna 297-3 and the wireless charging antenna 297-5 from the NFC antenna 297-3 and connect at least a portion of the radiator to the wireless charging antenna 297-5.

[0064] According to embodiments, at least one function of the MST communication module 210, NFC communication module 230, or wireless charging module 250 may be controlled by an external processor (e.g., processor 120). According to embodiments, at least one designated function of the MST communication module 210 or NFC communication module 230 (e.g., payment function) may be executed in a Trusted Execution Environment (TEE). According to embodiments, the TEE may form an execution environment in which, for example, at least some designated areas of memory 130 are allocated for executing functions requiring a relatively high level of security (e.g., financial transaction or personal information related functions). In this case, for example, access to at least one designated area of ​​memory 130 may be restricted depending on the entity accessing it or the application executing in the TEE.

[0075] According to various embodiments, the state in which the first housing 310 slides at least partially in the second space of the second housing 320 can be defined as a first state of the electronic device (e.g., a closed state, hereinafter referred to as "closed state").

[0076] According to various embodiments, the state in which the first housing 310 slides out of the second space of the second housing 320 can be defined as the second state of the electronic device (e.g., the open state, hereinafter referred to as the "open state").

[0077] According to various embodiments, the first state may be referred to as a first form, and the second state may be referred to as a second form. For example, the first form may include a normal state, a reduced state, or a closed state, and the second form may include an open state. In embodiments, the electronic device 300 may form a third state (e.g., an intermediate state) between the first state and the second state.

[0079] According to an embodiment, the flexible display 330 may include a first portion 391 (e.g., a fixed display area) that is always visible to the outside in both an open and closed state, and a second portion 392 (e.g., a variable display area) that is visible to the outside in an intermediate state or an open state. For example, the first portion 391 of the flexible display 330 may have a first size, and the second portion 392 of the flexible display 330 may have a second size.

[0080] According to an embodiment, in the closed state, the second portion 392 of the flexible display 330 can be accommodated in the first space of the first housing 310 or in the second space of the second housing 320. According to an embodiment, in an intermediate or open state, at least a portion of the second portion 392 of the flexible display 330 can slide out of the first space of the first housing 310 or the second space of the second housing 320 to become visible to the outside of the electronic device 300. For example, according to an embodiment, in conjunction with the sliding of the first housing 310 in a first direction (X direction), the second portion 392 of the flexible display 330 can slide out of the first space of the first housing 310 or the second space of the second housing 320, thereby becoming visible to the outside.

[0081] According to embodiments, the electronic device 300 may include a guide member (not shown) for guiding the movement of a second portion 392 of the flexible display 330 in conjunction with the sliding movement of the first housing 310. For example, the guide member may include a roller (not shown) that rotates according to the sliding movement of the first housing 310, a multi-jointed hinge (not shown) provided around the outer peripheral surface of the roller and sliding the second portion 392 of the flexible display 330 in or out based on the rotation of the roller, and / or a sliding plate (not shown) coupled to the multi-jointed hinge and supporting the externally visible second portion 392 of the flexible display 330 in conjunction with the sliding movement of the first housing 310. According to various embodiments, the form and structure of the guide member (not shown) for guiding the sliding movement of the first housing 310 of the flexible display 330 of the second portion 392 may be modified or changed in various ways.

[0082] According to an embodiment, in the closed state, at least a portion of the first housing 310 can slide within the second space of the second housing 320. For example, according to an embodiment, the direction in which the first housing 310 slides within the second space of the second housing 320 can be a second direction (-X direction) opposite to the first direction (X direction).

[0083] Reference Figure 3 According to the embodiment, the electronic device 300 can maintain the first housing 310 and the second housing 320 in a combined state, such that in the closed state, there is a first distance d1 between the first side surface 3121 and the fourth side surface 3221.

[0084] According to an embodiment, the flexible display 330, in its closed state, can have a display area of ​​a first size, wherein only the first portion 391 is visible to the outside, while the second portion 392 is not visible to the outside. According to an embodiment, the flexible display 330, in its closed state, can have a first width corresponding to a first distance d1.

[0085] Reference Figure 4 In the open state, the electronic device 300 according to the embodiment can keep the first housing 310 sliding out of the second housing 320 or being pulled out of the second housing 320, such that the first side 3121 and the fourth side 3221 have a second interval distance d (d = d1 + d2), and the fourth side 3221 is extended by a specific distance d2.

[0086] According to an embodiment, in the open state, the display area of ​​the flexible display 330 can be expanded to a second size corresponding to the area of ​​the second portion 392. For example, since the first portion 391 and the second portion 392 are visible to the outside in the open state, the flexible display 330 can have a display area of ​​the sum of the first size and the second size. According to an embodiment, the flexible display 330 can have a second width corresponding to the distance (e.g., d1 + d2), the distance being the sum of the first distance d1 and the second distance d2 in the open state, and the second width can be greater than the first width.

[0139] According to an embodiment, in the open state, a portion of the first housing 310 of the electronic device 300 can slide out of the second housing 320 in a first direction (X direction). Therefore, the second central axis (B-axis) of the electronic device 300 can be located in the first direction (X direction) of the first central axis (A-axis) of the electronic device 300. For example, the center C2 of the second coil 712 can be positioned in the first direction (X direction) from the center C1 of the first coil 711.

[0143] According to another embodiment, in the open state, the second central axis (axis B) of the electronic device 300, which passes through the center of the electronic device 300, may not pass through the center C2 of the second coil 712.

[0151] According to an embodiment, the first coil 711 may be wound to have a first gap K1 in a first region 901 of the first coil 711. For example, a first portion 911 of the first coil 711 disposed from the center C1 of the first coil 711 in a first direction (X direction) may be arranged to substantially have the first gap K1.

[0152] According to an embodiment, the first coil 711 may be wound to have a second gap K2 in a second region 902 of the first coil 711. For example, a second portion 912 of the first coil 711, disposed from the center C1 of the first coil 711 in a second direction (-X direction), may be arranged to substantially have a second gap K2. According to an embodiment, the second gap K2 may be substantially the same as the first gap K1. According to an embodiment, since the second gap K2 and the first gap K1 are substantially the same, the magnetic field generated by the first coil 711 will not deviate from the first central axis (axis A) of the electronic device 300 in a particular direction.

[0153] According to an embodiment, the gap of the first coil 711 (e.g., the first gap K1 or the second gap K2) can be defined as the shortest distance between a portion of the nth winding coil and the (n+1)th winding coil. For example, the gap of the first coil 711 (e.g., the first gap K1 or the second gap K2) can be the distance between a portion of the nth winding coil and a portion of the (n+1)th winding coil, which can be the shortest distance in a direction parallel to the movement direction of the first housing 310 of the electronic device 300 (e.g., the +X or -X axis direction).

[0154] According to an embodiment, when the short-range communication function is activated, the processor 120 of the electronic device 300 can identify whether the electronic device is in a closed state, and if the electronic device is in a closed state, the first coil 711 is activated so that the magnetic field of the electronic device 300 for short-range communication can be formed to be substantially symmetrical around the center of the electronic device 300 in a substantially closed state.

[0159] According to an embodiment, the second coil 712 may be wound to have a third gap K3 in the third region 903 of the second coil 712. For example, the third portion 921 of the second coil 712 disposed from the center C2 of the second coil 712 of the electronic device 300 in a first direction (X direction) may be arranged to substantially have a third gap K3.

[0160] According to an embodiment, the second coil 712 can be wound to have a fourth gap K4 in the fourth region 904 of the second coil 712. For example, the fourth portion 922 of the second coil 712, disposed from the center C2 of the second coil 712 of the electronic device 300 in the second direction (-X direction), can be arranged to substantially have a fourth gap K4. According to an embodiment, the fourth gap K4 can be larger than the third gap K3. According to an embodiment, the fourth gap K4 can increase as it is further away from the second central axis (axis B) of the electronic device 300. For example, the fourth portion 922 of the second coil 712, disposed from the second central axis (axis B) of the electronic device 300 in the second direction (-X direction), can be arranged such that its gap increases as it is further away from the second central axis (axis B).

For example, the fourth direction (-Z direction) can be opposite to the third direction (Z direction). According to an embodiment, as shown in the reference... Figure 9b The second coil 712 can form a ring-shaped antenna radiator, which is wound around the center C2 of the second coil 712 a specified number of times to have a gap therebetween based on the center C2.

[0171] According to an embodiment, the circuit board 701 may include a shielding layer 1021 formed from the second coil 712 in a fourth direction (-Z direction). According to an embodiment, the shielding layer 1021 may include a shielding member and function as a core for increasing the magnetic force generated by the first coil 711 and / or the second coil 712.

Referring below, reference will be made to... Figure 11 Based on the second coil 712 Figure 8 , Figure 9b and Figure 10 Features that are not described in the text or that are different from those features are described.

[0176] Reference Figure 11 ,and Figure 9b The embodiments shown may differ, and the line width (or thickness) of the second coil 712 according to the embodiments may not be constant.

[0177] According to an embodiment, the center C2 of the second coil 712 may be disposed on a second central axis (axis B) of the electronic device 300 passing through the center of the electronic device 300 when it is in the open state. According to an embodiment, based on the second central axis (axis B) of the electronic device 300, the second coil 712 may be divided into a third region 903 and a fourth region 904.

[0178] According to an embodiment, the third region 903 of the second coil 712 may be a region located on the second central axis (axis B) of the electronic device 300 in the first direction (X direction), and includes the third portion 1111 of the second coil 712.

Figure 1 The memory 130 in the memory can store instructions that, when executed, cause the processor 120 to perform actions. Figure 12 At least some of the operations shown.

[0185] In operation 1210, the electronic device 300 according to the embodiment can activate a wireless charging function or a short-range communication function. According to the embodiment, the processor of the electronic device 300 (e.g., Figure 1 The processor 120 in the device can activate (or execute) short-range communication functions (e.g., wireless charging, MST communication, and NFC communication) based on specified events. According to an embodiment, the event for executing the short-range communication function can be various user inputs to the electronic device 300, which may include, for example, on a display (e.g., ...). Figure 1 The input can be made via touch input, voice input, or pressing a physical button exposed on the outside of the electronic device 300 (such as the display module 160). In an embodiment, when the wireless charging device (e.g., Figure 13When the wireless charging pad 1300 is within a specified distance, the wireless charging function of the electronic device 101 can be activated.

[0186] In operation 1220, the electronic device 300 according to the embodiment can identify whether the current state is a closed state. For example, when the wireless charging function or short-range communication function is activated, the electronic device 300 can detect whether the current state is a closed state.

[0187] According to an embodiment, if the current state is a closed state (e.g., the result of operation 1220 is "yes"), then the electronic device 300 can perform operation 1230.

[0188] According to an embodiment, if the current state is not a closed state (e.g., the result of operation 1220 is "no"), then the electronic device 300 can perform operation 1240. For example, if the current state is an open state (e.g., the result of operation 1220 is "no"), then the electronic device 300 can perform operation 1240.

[0189] In operation 1230, the electronic device 300 according to the embodiment can activate the first coil (e.g., Figure 9a The first coil 711 in the middle is used to perform wireless charging or short-range communication functions.

[0190] According to an embodiment, activating the first coil 711 can be defined as connecting the first coil 711 to a wireless communication module (e.g., Figure 2 The wireless communication module 192) or wireless charging module (e.g., Figure 2 The wireless charging module 250 is electrically (or operably) connected to the operation.

[0191] In operation 1240, the electronic device 300 according to the embodiment can activate the second coil (e.g., Figure 9b The second coil 712 in the middle is used to perform wireless charging or short-range communication functions.

[0192] According to an embodiment, activating the second coil 712 can be defined as connecting the second coil 712 to a wireless communication module (e.g., Figure 2 The wireless communication module 192) or wireless charging module (e.g., Figure 2 The wireless charging module 250 is electrically (or operably) connected to the operation.

[0193] According to an embodiment, the electronic device 300 can selectively include a short-range communication module (e.g., Figure 2 The wireless communication module 192 or Figure 2 The wireless charging module 250 is connected to the first coil or the second coil.

[0194] Figure 13 This is an example illustrating a scenario in which an electronic device 300 according to various embodiments of the present disclosure is mounted on a wireless charging pad 1300 to wirelessly receive power.

[0195] Reference Figure 13 Electronic device 300 according to various embodiments (e.g., Figure 1 The electronic device 300 (101) can be mounted on the wireless charging pad 1300 to wirelessly receive power. For example, the wireless charging pad 1300 may include an external coil 1301 for wireless power transmission, and the electronic device 300 can be powered by a coil resonating with the external coil 1301 (e.g., Figure 9b The second coil 712 in the middle wirelessly receives power.

[0196] According to an embodiment, when the electronic device 300 is in the open state as shown in the illustrated example, the electronic device 300 can activate the second coil 712 and wirelessly receive power through the activated second coil 712. According to an embodiment, in the open state, the center C2 of the second coil 712 is located on the central axis of the electronic device 300 (e.g., ...). Figure 9b On axis B), the efficiency of the wireless charging function can be improved compared to the state where the first coil 711 is activated. According to the embodiment, the efficiency of the wireless charging function can be defined as the rate at which the battery of the electronic device 300 is charged using the wireless charging function. For example, the wireless charging pad 1300 can be manufactured with dimensions based on the width of the electronic device 300 in the closed state. Therefore, when the electronic device 300 is in the open state, if the center C1 of the first coil 711 is aligned with the outer coil 1301, the electronic device 300 may not be fixed to the wireless charging pad 1300, and if the electronic device 300 is fixedly positioned on the wireless charging pad, the center C1 of the first coil 711 may not be aligned with the outer coil 1301, thereby reducing the efficiency of the wireless charging function. In this case, if a second coil 712 is used, the center C2 of the second coil 712 is better aligned with the outer coil 1301 than the center C1 of the first coil 711, thereby reducing the reduction in the efficiency of the wireless charging function.

For example, the external device 1400 can be an electronic watch that supports wireless charging.

[0199] According to an embodiment, when the electronic device 300 is in the open state as shown in the illustrated example, the electronic device 300 can activate the second coil 712 (e.g., Figure 9b The second coil 712 is activated, and power is wirelessly transmitted through the activated second coil 712. According to an embodiment, the center C2 of the second coil 712 is formed on the central axis (axis B) of the electronic device 300 in the open state (e.g., axis B in FIG. 9B), thus improving the efficiency of the wireless charging function compared to using the first coil 711 for wireless power transmission. According to an embodiment, the efficiency of the wireless charging function can be defined as the rate at which the battery of the external device 1400 is charged using the wireless charging function.

[0200] According to an embodiment, the electronic device 300 can activate the coil that is closer to the center of the outer coil included in the outer device 1400, either the center C1 of the first coil 711 or the center C2 of the second coil 712.
