The communication module (190) may include one or more communication processors that operate independently of the processor (120) (e.g., application processor) and support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., cellular communication module, short-range wireless communication module, or GNSS (global navigation satellite system) communication module) or a wired communication module (194) (e.g., LAN (local area network) communication module, or power line communication module). The corresponding communication module among these communication modules can communicate with an external electronic device (104) through a first network (198) (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network (199) (e.g., a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can identify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)) stored in the subscriber identification module (196).
[0036] The wireless communication module (192) can support 5G networks and next-generation communication technologies following 4G networks, for example, new radio access technology. NR access technology can support high-speed transmission of high-capacity data (enhanced mobile broadband (eMBB)), minimization of terminal power and connection of multiple terminals (massive machine type communications (mMTC)), or high reliability and low latency (ultra-reliable and low-latency communications (URLLC)). The wireless communication module (192) can support a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate, for example. The wireless communication module (192) can support various technologies for securing performance in the high-frequency band, such as beamforming, massive MIMO (multiple-input and multiple-output), full-dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large-scale antenna.

According to one embodiment, all or part of the operations performed on the electronic device (101) may be performed on one or more of the external electronic devices (102, 104, or 108). For example, if the electronic device (101) needs to perform a function or service automatically or in response to a request from a user or another device, the electronic device (101) may request one or more external electronic devices to perform at least part of the function or service instead of performing the function or service itself or additionally.

The electronic device (101) may provide the result as is or additionally processed as at least part of the response to the request. For this purpose, for example, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used. The electronic device (101) may provide ultra-low latency services using, for example, distributed computing or mobile edge computing. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device.

[0041] FIG. 2 illustrates an electronic device, an accessory device, and a wireless charging device.
[0042] Referring to FIG. 2, the electronic device (101) can be used together with an accessory device (301).
[0043] An accessory device (301) may be coupled to an electronic device (101). For example, the electronic device (101) may include a housing (210) that defines the exterior of the electronic device (101). The housing (210) may at least partially define the lateral side (211) of the electronic device (101) and the rear (212) of the electronic device (101). The accessory device (301) may include a plate (311) and a side wall (312) that form a space for accommodating the housing (210) of the electronic device (101). The plate (311) and the side wall (312) may define an internal volume having a size and shape for accommodating the housing (210). The housing (210) may be coupled to the internal volume in an interference fit or tight fit manner.
[0044] When the accessory device (301) is coupled to the electronic device (101), the accessory device (301) can enclose a portion of the exterior of the electronic device (101). For example, the side wall (312) of the accessory device (301) can enclose at least a portion of the side (211) of the electronic device (101), and the plate (311) of the accessory device (301) can enclose at least a portion of the rear (212) of the electronic device (101). The accessory device (301) can protect the electronic device (101) by enclosing a portion of the exterior of the electronic device (101).
[0045] The electronic device (101) may be electrically connected to an external wireless charging device (302) while combined with a case. For example, the electronic device (101) may include an antenna (220) disposed within a housing (210). The antenna (220) may be configured to receive power transmitted from the external wireless charging device (302). The battery of the electronic device (101) (e.g., the battery (189) of FIG. 1) may be charged based on the power received through the antenna (220). For example, the external wireless charging device (302) may include a magnet (350) for coupling to an accessory device (301) of the external wireless charging device (302) and a transmitting antenna (360) configured to transmit power. In order to receive power transmitted from the transmitting antenna (360) of the external wireless charging device (302), the antenna (220) of the electronic device (101) can be aligned with the transmitting antenna (360) of the external wireless charging device (302). The magnet (350) of the external wireless charging device (302) can be paired with the magnet (320) of the accessory device (301). Due to the attractive force between the magnet (350) of the external wireless charging device (302) and the magnet (320) of the accessory device (301), the external wireless charging device (302) can be magnetically coupled to the accessory device (301).
[0046] The electronic device (101) may be operatively coupled with the accessory device (301). For example, the electronic device (101) may be configured to identify the coupling of the accessory device (301) to the electronic device (101) and, based on the identification of the coupling, to perform authentication of the accessory device (301). Once the authentication is completed, a communication channel may be established between the electronic device (101) and the external wireless charging device (302). The electronic device (101) and the accessory device (301) may be configured to communicate wirelessly through the communication channel.
[0047] The electronic device (101) and the accessory device (301) may include components for identifying the connection of the accessory device (301) when the accessory device (301) is connected to the accessory device (301). The accessory device (301) may include a magnet (320) that generates a magnetic field. For example, the magnet (320) may be placed within the plate (311) of the accessory device (301). The electronic device (101) may include a component for identifying the connection of the accessory device (301) to the electronic device (101) through interaction with the magnet (320). The electronic device (101) may include a conductive portion (230) for identifying the connection of the accessory device (301) to the electronic device (101). The conductive portion (230) may be referred to as a dummy pattern. The magnet (320) of the accessory device (301) can be paired with the magnet (350) of the external wireless charging device (302) to secure the external wireless charging device (302). As described above, the external wireless charging device (302) can be magnetically coupled to the accessory device (301) by the attractive force between the magnet (350) of the external wireless charging device (302) and the magnet (320) of the accessory device (301).
[0048] When the accessory device (301) is coupled to the electronic device (101), the magnet (320) may affect the electronic components of the electronic device (101). For example, the magnet (320) may interfere with the signals of the electronic device (101) or with the power transmitted from the external wireless charging device (302). Such interference may affect the performance of the electronic device (101). To reduce such interference, the magnet (320) of the accessory device (301) may be positioned at a designated location relative to the electronic device (101) when the accessory device (301) is coupled to the electronic device (101). In the present disclosure, the designated location of the magnet (320) may be referred to as a pre-specified relative location of the magnet (320) to the electronic device (101) while the accessory device (301) is coupled to the electronic device (101).
[0049] If the accessory device (301) is manufactured by the manufacturer of the electronic device (101) and / or by an approved third-party manufacturer, the magnet (320) of the accessory device (301) may be located within a designated position relative to the electronic device (101). For example, when the accessory device (301) is coupled to the electronic device (101), the position of the magnet (320) relative to the electronic device (101) may correspond to a designated position.
[0050] If, when the accessory device (301) is coupled to the electronic device (101), the magnet (320) is not located within the designated position, performance degradation of the electronic device (101) may occur. For example, electronic components such as the display or camera of the electronic device (101) may be affected by the magnetic field from the magnet (320). A magnet (320) located within a position different from the designated position may affect the operation of the display or camera of the electronic device (101) and degrade the performance of the display or camera. Because it is difficult to determine whether the performance degradation of the electronic device (101) is caused by the magnet (320) placed within the accessory device (301), it may be necessary to determine whether the position of the magnet (320) of the accessory device (301) relative to the electronic device (101) corresponds to the specified position while the accessory device (301) is coupled to the electronic device (101).
[0051] The electronic device (101) may include a conductive portion (e.g., the conductive portion (230) of FIG. 4). The conductive portion (230) may be used to identify whether the position of the magnet (320) corresponds to a designated position when the accessory device (301) is coupled to the electronic device (101). Hereinafter, examples of the conductive portion (230) are described with reference to the drawings.
[0052] Figure 3 is a block diagram of an electronic device and an accessory device.
[0053] Referring to FIG. 3, the electronic device (101) may include at least one processor (e.g., processor (120) of FIG. 1), memory (e.g., memory (130) of FIG. 1), antenna (220), PMIC (power management integrated circuitry) (240), battery (e.g., battery (189) of FIG. 1), conductive part (230), and RFIC (radio frequency integrated circuit) (370).
[0054] At least one processor (120) may include a processing circuit. At least one processor (120) may include an application processor (AP, e.g., a central processing unit (CPU)) and / or a communication processor (CP, e.g., a modem), but is not limited thereto. At least one processor (120) may include a graphics processing unit (e.g., a GPU), a neural processing unit (NPU) (e.g., an artificial intelligence (AI) chip), a wireless-fidelity (Wi-Fi) chip, a Bluetooth chip, a global positioning system (GPS) chip, a near field communication (NFC) chip, connectivity chips, a sensor controller, a touch controller, a finger-print sensor controller, a display drive integrated circuit (DDI), an audio CODEC chip, a universal serial bus (USB) controller, a camera controller, an image (922) processing IC, a microprocessor unit (MPU), a system on chip (SoC), an IC, or a similar circuit.
[0055] The memory (130) may include one or more storage media for storing instructions. It should be understood that the blocks of each flowchart and combinations of flowcharts in the present disclosure may be performed by one or more computer programs that include computer-executable instructions. One or more computer programs may be stored in a single memory, or one or more computer programs may be divided into different parts stored in different multiple memories.
[0056] The electronic device (101) may be configured to charge a battery based on power transmitted from an external wireless charging device (302) via a PMIC (240) and an antenna (220). The antenna (220) may be configured to receive power transmitted from a transmitting antenna (360) of the external wireless charging device (302). In an example, not limited to, the antenna (220) may include an antenna utilizing NFC wireless charging and communication techniques. Or, in an example, not limited to, the antenna (220) may include an antenna utilizing RFID (radio frequency identification) wireless charging and communication techniques. Or, in an example, not limited to, the antenna (220) may include an antenna utilizing WPC (wireless power consortium) wireless charging and communication techniques.
[0057] For example, the antenna (220) can be used for wireless charging based on a magnetic power profile (MPP) mode defined in the Qi standard (Qi 2.0). The Qi 2.0 wireless charging standard can provide magnetic alignment corresponding to a state where the external wireless charging device (302) is aligned with the electronic device (101) in order to increase the efficiency and stability of wireless charging. The Qi 2.0 standard can provide rapid wireless charging by supporting power of 15W or more. For example, in the case of an external wireless charging device (302) that supports an MPP mode of 15W or more, it can transmit an exchange identification (XID) packet indicating that it is a device that supports MPP to the electronic device (101). The electronic device (101) can identify that the external wireless charging device (302) is a device that supports MPP mode through the XID packet and perform wireless charging operations based on the protocol of the MPP mode. The Qi 2.0 standard can support wireless charging protocols for external wireless charging devices based on the conventional Qi 1 standard. For example, in the case of an external wireless charging device (302) that does not support the Qi 2.0 standard, the Qi 2.0 standard can provide wireless charging protocols based on a BPP (baseline power profile) mode of 5W or less or an EPP (extended power profile) mode of 15W or less.
[0058] The PMIC (240) may be configured to store power received through the antenna (220) in a battery. Here, storing the power in the battery may be referred to as charging the electronic device (101). In FIG. 3, the PMIC (240) is shown as a separate hardware component from at least one processor (120), but the present disclosure is not limited thereto. For example, the PMIC (240) may be implemented as a single chip with at least one processor (120). Although not illustrated, the electronic device (101) may include a low voltage direct current-direct current converter (LDC) configured to convert voltage to provide power transmitted from an external wireless charging device (302) to the PMIC (240).
[0059] The conductive portion (230) may be positioned around the antenna (220). As described below, the conductive portion (230) may be positioned to at least partially surround the antenna (220). The conductive portion (230) may be electrically connected to at least one processor (120). For example, the conductive portion (230) may include one or more ports (e.g., ports (421, 422) of FIG. 5) for electrical connection with at least one processor (120).
[0060] The RFIC (370) can be electrically connected to the conductive part (230) and the antenna (220). The RFIC (370) can be used to identify a measurement value (e.g., voltage standing wave ratio (VSWR)) based on the reflected signal of the conductive part (230) through a coupler (381). For example, the coupler (381) can provide the RFIC (370) with power corresponding to the forward direction from the RFIC (370) toward the conductive part (230) and power reflected from the conductive part (230). The coupler (381) can obtain a coupling signal of the signal corresponding to the direction from the RFIC (370) toward the conductive part (230) (e.g., forward coupling signal) and a coupling signal of the reflected signal opposite to said direction (e.g., reverse coupling signal). The forward coupling signal and reverse coupling signal provided to the RFIC (370) through the coupler (381) can be used to identify the voltage standing wave ratio (VSWR) of the conductive part (230). The conductive part (230) can be optionally connected to the coupler (381) through the switch circuit (382).
[0061] The accessory device (301) may include a magnet (320). When the accessory device (301) is coupled to the electronic device (101), the conductive portion (230) may overlap the magnet (320). The area over which the conductive portion (230) overlaps the magnet (320) may be maximum when the magnet (320) is positioned at a designated location. For example, when the magnet (320) is spaced apart from the designated location, the area over which the conductive portion (230) overlaps the magnet (320) may be narrower than the area over which the conductive portion (230) overlaps the magnet (320) when the magnet (320) is positioned at the designated location.
[0062] The conductive portion (230) may be configured to interact (e.g., couple) with the magnet (320) of the accessory device (301). At least one processor (120) may be configured to identify the amount of change in the parameter value of the conductive portion (230) based on the interaction. For example, the parameter may include, but is not limited to, the voltage standing wave ratio (VSWR) for the conductive portion (230) based on the interaction, the capacitance caused in the conductive portion (230) based on the interaction, and / or inductance. At least one processor (120) may be configured to identify whether the magnet (320) of the accessory device (301) is located within a designated position for the electronic device (101) based on the amount of change in the parameter value.
[0063] The electronic device (101) may use a conductive part (230) as a component for identifying the coupling of the accessory device (301) and the designated location of the magnet (320). Because the conductive part (230) has a simple structure, the conductive part (230) can be easily placed around the antenna (220) within a housing (e.g., the housing (210) of FIG. 2). By using the conductive part (230), the electronic device (101) can secure mounting space within the housing (210) and, as described below, reduce noise.
[0064] FIGS. 4 and 5 illustrate an antenna of an electronic device. FIG. 6 illustrates an electronic device combined with an accessory device.
[0065] Referring to FIG. 4, an electronic device (e.g., the electronic device (101) of FIG. 2) may include an antenna (220). The antenna (220) may be used to communicate with an accessory device (e.g., the accessory device (301) of FIG. 2) and / or to receive power transmitted from an external wireless charging device (e.g., the external wireless charging device (302) of FIG. 2).
[0066] According to one embodiment, the antenna (220) may be configured to receive power wirelessly from an external wireless charging device (302). The antenna (220) may support one or more of various wireless charging methods, including magnetic resonance or magnetic induction. The antenna (220) may include a coil disposed on a substrate (410). For example, the coil may be wound multiple times with increasing radius with respect to a central area so that the coil is approximately flat. In the sense that the antenna (220) is implemented as a coil, the antenna (220) may be referred to as a wireless charging coil or an inductive coil.
[0067] According to one embodiment, the conductive portion (230) may be positioned to at least partially wrap around the antenna (220). For example, the conductive portion (230) may have a roughly semicircular shape by extending along a portion of the edge of the coil containing concentric circles. The conductive portion (230) may be spaced apart from the antenna (220) without contacting the antenna (220). The antenna (220) illustrated in FIG. 4 may include a port (421). Through the port (421), the conductive portion (230) may be electrically connected to at least one processor (e.g., at least one processor (120) in FIG. 3). For example, the port (421) of the antenna (220) may be connected to a printed circuit board on which at least one processor (120) is placed. The conductive portion (230) having the port (421) may include a wire that transmits a signal and a wire that is electrically connected to ground. In the case of a conductive part (230) having one port (421), it can have a simple structure.
[0068] Referring to FIG. 5, the conductive portion (230) may include two ports (421, 422). When the conductive portion (230) includes two ports (421, 422), the conductive portion (230) may have a roughly circular shape. The conductive portion (230) may be electrically connected to at least one processor (120) through the two ports (421, 422). The conductive portion (230) including the two ports (421, 422) may include two wires that carry opposite phase sinholes and a wire that is electrically connected to ground. The conductive portion (230) including the two ports (421, 422) may have high noise resistance.
[0069] Referring to FIG. 6, an accessory device (301) can be coupled to an electronic device (101). According to one embodiment, when the accessory device (301) is coupled to the electronic device (101), the magnet (320) of the accessory device (301) may overlap at least partially with the conductive portion (230). For example, the shape of the magnet (320) may correspond to the shape of the conductive portion (230). For example, as shown in FIG. 6, the magnet (320) may have a ring shape having an opening. When the accessory device (301) is coupled to the electronic device (101), the position of the antenna (220) of the electronic device (101) may correspond to the ring-shaped opening, and the conductive portion (230) may overlap with the ring-shaped conductive portion (230). When looking at the plate (311) of the accessory device (301) from above (+z direction), the conductive portion (230) can be superimposed on the ring-shaped magnet (320).
[0070] According to one embodiment, a designated position of the magnet (320) of the accessory device (301) for the electronic device (101) may correspond to a position where the area of the conductive portion (230) overlapping the magnet (320) of the accessory device (301) is maximized. For example, when the magnet (320) of the accessory device (301) is located within the designated position, the conductive portion (230) may be maximally overlapped with the ring-shaped magnet (320). As the area of the conductive portion (230) overlapping the magnet (320) is maximized, the interaction between the magnet (320) and the conductive portion (230) may be most strongly formed. As the above interaction is formed most strongly, the amount of change in the parameter value of the conductive part (230) caused by the above interaction may indicate that the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a designated position.
[0071] For example, the amount of change in the measured value based on the reflected signal for the conductive part (230) due to the above interaction (e.g., the amount of change in VSWR) may be maximum when the magnet (320) is positioned at a designated location. For example, the value of the capacitance and / or inductance caused by the above interaction in the conductive part (230) may be maximum when the magnet (320) is positioned at a designated location.
[0072] According to one embodiment, at least one processor (120) may be configured to identify whether the location of the magnet (320) corresponds to a designated location based on information regarding the interaction between the conductive part (230) and the magnet (320). By using the conductive part (230) to identify whether the location of the magnet (320) of the accessory device (301) corresponds to a designated location, at least one processor (120) may be configured to identify whether the accessory device (301) degrades the performance of the electronic device (101). As described above, if the accessory device (301) is not manufactured by the manufacturer of the electronic device (101) and / or an approved third-party manufacturer, when the accessory device (301) is coupled to the electronic device (101), the location of the magnet (320) relative to the electronic device (101) may not correspond to a designated location. If the position of the magnet (320) does not correspond to a designated position, performance degradation of the electronic device (101) caused by the magnet (320) may occur. An electronic device (101) according to one embodiment can identify whether the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a designated position by using a conductive part (230) of a simple structure.
[0073] FIG. 7 is a flowchart illustrating the operation of an electronic device that identifies whether the position of a magnet corresponds to a specified position.
[0074] The operations illustrated in FIG. 7 may be performed by the electronic device (101) of FIG. 2. For example, at least some of the operations may be performed by at least one processor of the electronic device (101) (e.g., at least one processor (120) of FIG. 3). For example, the operations may be referred to as operations performed by the electronic device (101) when instructions stored in memory (e.g., memory (130) of FIG. 3) are executed individually or collectively by at least one processor (120). The above descriptions may be applied substantially the same way to the flowcharts of FIG. 8 and FIG. 10 described below.
[0075] Referring to FIG. 7, in operation 701, the electronic device (101) may be configured to identify the amount of change in the parameter value of the conductive part (e.g., the conductive part (230) of FIG. 2) of the electronic device (101) when an accessory device (e.g., the accessory device (301) of FIG. 2) is coupled to the electronic device (101).
[0076] According to one embodiment, at least one processor (120) may be configured to identify the amount of change in the parameter value of the conductive portion (230) caused by the magnet (320) of the accessory device (301) adjacent to the conductive portion (230) of the electronic device (101). For example, when the accessory device (301) is coupled to the electronic device (101), the accessory device (301) may enclose at least a portion of the housing of the electronic device (101) (e.g., the housing (210) of FIG. 2). The magnet (320) contained within the accessory device (301) may overlap at least partially with the conductive portion (230) contained within the electronic device (101). When manufacturing the accessory device (301), the magnet (320) may be mounted within the accessory device (301) so as to overlap with the conductive portion (230) when the accessory device (301) is coupled to the electronic device (101).
[0077] As the magnet (320) of the accessory device (301) overlaps with the conductive part (230) of the electronic device (101), an interaction may occur between the magnet (320) and the conductive part (230). At least one processor (120) electrically connected to the conductive part (230) may be configured to identify the amount of change in parameter values of the conductive part (230) caused by said interaction. The parameters may include a measurement value based on a reflected signal (e.g., VSWR based on the reflected signal or the measurement of the reflected signal), capacitance, and / or inductance. For example, at least one processor (120) may be configured to identify a measurement value based on the reflected signal for the conductive part (230), a capacitance value caused in the conductive part (230), and / or an inductance value caused in the conductive part (230).
[0078] In operation 703, the electronic device (101) may be configured to identify whether the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a specified position based on the amount of change of the parameter value.
[0079] According to one embodiment, the amount of change in the parameter value of the conductive part (230) of the electronic device (101) caused by the magnet (320) of the accessory device (301) may change according to the area of the conductive part (230) superimposed on the magnet (320). For example, the measured value based on the reflected signal, the capacitance value, and / or the inductance value may increase as the interaction between the magnet (320) and the conductive part (230) becomes stronger, since the measured value based on the reflected signal is based on the interaction between the magnet (320) and the conductive part (230). The amount of change in the measured value based on the reflected signal, the capacitance value, and / or the inductance value may be substantially proportional to the area of the conductive part (230) superimposed on the magnet (320). When the position of the magnet (320) corresponds to a designated position, the area of the conductive portion (230) overlapping the magnet (320) is maximum, so the amount of change of the measured value based on the reflection signal, the capacitance value, and / or the inductance value may be within a designated range when the position of the magnet (320) corresponds to a designated position.
[0080] According to one embodiment, the memory (130) may store information related to threshold values indicating that the position of the magnet (320) of the accessory device (301) corresponds to a specified position. For example, the threshold values may include a first threshold value related to a change in the measured value based on the reflected signal (e.g., a change in VSWR), a second threshold value related to a capacitance value, and / or a third threshold value related to an inductance value. At least one processor (120) may be configured to identify whether the position of the magnet (320) corresponds to a specified position by comparing a parameter according to the identified information with the specified threshold value.
[0081] Hereinafter, a specific operation in which the electronic device (101) identifies whether the position of the magnet (320) corresponds to a designated position and an operation of the electronic device (101) performed according to the position of the magnet (320) are described.
[0082] FIG. 8 is a flowchart illustrating the operation of an electronic device that identifies whether the position of a magnet corresponds to a specified position. FIG. 9 illustrates an example of a notification provided by the electronic device.
[0083] In the present disclosure, expressions such as "greater than" or "less than" may be used to determine whether a specific condition is satisfied or fulfilled; however, this is merely for the purpose of expressing an example and does not exclude expressions such as "greater than" or "less than." Conditions described as "greater than" may be replaced with "greater than", and conditions described as "less than" may be replaced with "less than".
[0084] Referring to FIG. 8, in operation 801, an electronic device (e.g., electronic device (101) of FIG. 2) may be configured to identify a change in a measurement value based on a reflected signal for a conductive part (230) when an accessory device (e.g., accessory device (301) of FIG. 2) is coupled to the electronic device (101).
[0085] According to one embodiment, when an accessory device (301) is coupled to an electronic device (101), an interaction may occur between the magnet (320) of the accessory device (301) and the conductive part (230). Due to the interaction between the magnet (320) of the accessory device (301) and the conductive part (230) of the electronic device (101), a change in the I (in-phase) value and Q (quadrature) value of the signal caused in the conductive part (230) may occur. When the position of the magnet (320) corresponds to a designated position, the overlap area between the magnet (320) and the conductive part (230) may be formed to the maximum. For example, at least one processor (e.g., at least one processor (120) of FIG. 2) electrically connected to the conductive part (230) may provide a signal to the conductive part (230). The above signal can be radiated by using the conductive part (230) as a radiator. Since the signal radiated through the conductive part (230) can be reflected by the magnet (320), the amount of reflection of the signal may vary depending on the area of the conductive part (230) that overlaps with the magnet (320). Depending on the change in the amount of reflection of the signal, a measurement value (e.g., VSWR value) based on the reflected signal for the conductive part (230) may vary. For example, since the amount of reflection may be maximum when the area of the conductive part (230) that overlaps with the magnet (320) is maximum, the amount of change in the VSWR value may be maximum when the position of the magnet (320) corresponds to a designated position.
[0086] In operation 803, the electronic device (101) may be configured to compare the identified amount of change with a first threshold value.
[0087] According to one embodiment, the first threshold value may be referenced as the amount of change in a measurement value based on a reflection signal caused in the conductive part (230) based on the interaction between the conductive part (230) and the magnet (320) when the position of the magnet (320) corresponds to a specified position (e.g., change in VSWR). For example, the amount of change in a measurement value based on a reflection signal exceeding the first threshold value may indicate that the position of the magnet (320) corresponds to a specified position. At least one processor (120) may be configured to compare the amount of change in a measurement value based on a reflection signal for the conductive part (230) identified in operation 801 with the first threshold value to identify whether the position of the magnet (320) corresponds to a specified position. If the amount of change in a measurement value based on a reflection signal identified exceeds the first threshold value, operation 805 may be performed. If the amount of change in the measurement value based on the identified reflection signal is less than or equal to the first threshold value, operation 809 may be performed.
[0088] In operation 805, the electronic device (101) may be configured to identify that the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a designated position.
[0089] According to one embodiment, when the accessory device (301) is manufactured by the manufacturer of the electronic device (101) and / or an authorized third-party manufacturer, when the accessory device (301) is coupled to the electronic device (101), the position of the magnet (320) of the accessory device (301) may correspond to a designated position. In this case, because the area of the conductive portion (230) of the electronic device (101) that overlaps with the magnet (320) is maximum, the amount of change in the measurement value based on the reflection signal for the conductive portion (230) (e.g., change in VSWR) may exceed a first threshold value. At least one processor (120) may be configured to identify that the position of the magnet (320) corresponds to a designated position based on identifying the amount of change in the measurement value based on the reflection signal that exceeds the first threshold value.
[0090] In operation 807, the electronic device (101) may be configured to perform wireless charging using an antenna (220).
[0091] According to one embodiment, at least one processor (120) may be configured to perform wireless charging using an antenna (220) based on identifying that the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a designated position. For example, at least one processor (120) may execute a protocol for wireless charging based on identifying the designated position.
[0092] As described above, a designated location of the magnet (320) can be referenced as a location that can reduce performance degradation of the electronic device (101). For example, power can be transmitted to the electronic device (101) from a transmitting antenna (e.g., the transmitting antenna (360) of FIG. 2) of an external wireless charging device (e.g., the external wireless charging device (302) of FIG. 2). If the location of the magnet (320) relative to the electronic device (101) is not a designated location, the wireless charging efficiency may be reduced due to interference from the magnet (320) with said power. Interference from the magnet (320) with said power within a designated location may be minimized. In a state where said interference is minimized, at least one processor (120) can improve wireless charging efficiency by performing wireless charging.
[0093] In operation 809, the electronic device (101) may be configured to identify that the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a position different from the specified position.
[0094] According to one embodiment, if the accessory device (301) is not manufactured by the manufacturer of the electronic device (101) and / or by an approved third-party manufacturer, when the accessory device (301) is coupled to the electronic device (101), the position of the magnet (320) of the accessory device (301) may correspond to a position different from a designated position. For example, the position of the magnet (320) relative to the electronic device (101) may be spaced apart from a designated position. In this case, since the area of the conductive portion (230) of the electronic device (101) overlapping the magnet (320) is not maximum, the amount of VSWR change for the conductive portion (230) may be less than or equal to a first threshold value. At least one processor (120) may be configured to identify that the position of the magnet (320) does not correspond to a designated position based on identifying the amount of VSWR change less than or equal to the first threshold value.
[0095] In operation 811, the electronic device (101) may be configured to provide a notification indicating the different location.
[0096] According to one embodiment, at least one processor (120) may be configured to provide a notification based on identifying that the position of the magnet (320) on the electronic device (101) corresponds to a position different from a designated position. The notification may be referred to as a notification to inform that the accessory device (301) may cause performance degradation of the electronic device (101). The notification may be provided in various forms. In the description below, a visual notification is described as an example of the notification, but the present disclosure is not limited thereto. For example, the electronic device (101) may provide an auditory notification through an audio module (e.g., the audio module (170) of FIG. 1) or a tactile notification through a haptic module (e.g., the haptic module (179) of FIG. 1).
[0097] Referring to FIG. 9, the electronic device (101) may include a display (910) (e.g., the display module (160) of FIG. 1). At least one processor (120) may be configured to display a visual object (920) on the display (910) by controlling the display (910).
[0098] According to one embodiment, at least one processor (120) may be configured to display a visual object (920) indicating the different location on a display (910) when it identifies that the location of the magnet of the accessory device (901) for the electronic device (101) corresponds to a location different from the designated location. Since the performance of the electronic device (101) may be degraded by the magnet contained within the accessory device (901) coupled to the electronic device (101), at least one processor (120) may guide the replacement of the accessory device (901) through the visual object (920).
[0099] According to one embodiment, as illustrated in FIG. 9, the visual object (920) may include text (921) and / or an image (922). For example, the text (921) may include text such as, “Please use genuine authenticated accessories. Using unauthenticated accessories may degrade the performance of the device.” For example, the image (922) may include an image (922) with an X mark superimposed on an accessory device (901). The text (921) and image (922) illustrated in FIG. 9 are merely exemplary and the embodiments of the present disclosure are not limited thereto.
[0100] An electronic device (101) according to one embodiment can identify a change in the parameter value of a conductive part (230) caused by the interaction between the magnet of the accessory device and the conductive part of the electronic device (101) (e.g., the conductive part (230) of FIG. 2), and can identify whether the position of the magnet corresponds to a designated position based on the change. Whether the position of the magnet corresponds to a designated position may correspond to whether the accessory device (901) coupled to the electronic device (101) is a genuine accessory device (901) manufactured by the manufacturer of the electronic device (101) and / or an approved third-party manufacturer. The electronic device (101) can identify an accessory device (e.g., the accessory device (901) of FIG. 9) that causes performance degradation of the electronic device (101) by using the conductive part (230). When the electronic device (101) identifies the accessory device (901), it may provide a notification to guide the replacement of the accessory device (901) without performing wireless charging.
[0101] FIG. 10 is a flowchart illustrating the operation of an electronic device that identifies whether the position of a magnet corresponds to a specified position.
[0102] In the operations illustrated in FIG. 8, a change in VSWR is described as an example of information, but said information may include a capacitance value caused in a conductive part (230) based on the interaction between a magnet (e.g., magnet (320) of FIG. 2) of an accessory device (e.g., accessory device (301) of FIG. 2) and a conductive part (e.g., conductive part (230) of FIG. 2) of an electronic device (e.g., electronic device (101) of FIG. 2). In the operations described in FIG. 10, the capacitance value may be replaced with an impedance value. Descriptions substantially identical to the descriptions above may not be described repeatedly, may be described briefly, or may be omitted.
[0103] Referring to FIG. 10, in operation 1001, the electronic device (101) may be configured to identify a capacitance value caused in the conductive part (230) based on the interaction between the magnet (320) of the accessory device (301) and the conductive part (230) when the accessory device (301) is coupled to the electronic device (101).
[0104] According to one embodiment, when an accessory device (301) is coupled to an electronic device (101), an interaction may occur between the magnet (320) of the accessory device (301) and the conductive part (230). Due to the interaction between the magnet (320) of the accessory device (301) and the conductive part (230) of the electronic device (101), capacitance may be induced in the conductive part (230). For example, if the conductive part (230) is formed of a metal material and the accessory device (301) is formed of a dielectric material, capacitance may be induced between the conductors facing each other. For at least one processor (120) electrically connected to the conductive part (230), the capacitance value may vary depending on the area of the conductive part (230) that overlaps with the magnet (320). For example, when the area of the conductive part (230) overlapping with the magnet (320) is maximum, the capacitance value caused in the conductive part (230) can be maximum, so when the position of the magnet (320) corresponds to a specified position, the capacitance value can be maximum.
[0105] In operation 1003, the electronic device (101) may be configured to compare the identified capacitance value with a second threshold value.
[0106] According to one embodiment, the second threshold value may be referenced as a capacitance value caused in the conductive portion (230) based on the interaction between the conductive portion (230) and the magnet (320) when the position of the magnet (320) corresponds to a specified position. For example, a capacitance value exceeding the second threshold value may indicate that the position of the magnet (320) corresponds to a specified position. At least one processor (120) may be configured to compare the capacitance value identified in operation 1001 with the second threshold value to identify whether the position of the magnet (320) corresponds to a specified position. If the identified capacitance value exceeds the second threshold value, operation 1005 may be performed. If the identified capacitance value is less than or equal to the second threshold value, operation 1009 may be performed.
[0107] In operation 1005, the electronic device (101) may be configured to identify that the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a designated position.
[0108] According to one embodiment, when the position of the magnet (320) of the accessory device (301) corresponds to a designated position, the capacitance value caused in the conductive portion (230) of the electronic device (101) that overlaps the magnet (320) is maximized, so the capacitance value caused in the conductive portion (230) may exceed a second threshold value. At least one processor (120) may be configured to identify that the position of the magnet (320) corresponds to a designated position based on identifying a capacitance value that exceeds the second threshold value.
[0109] In operation 1007, the electronic device (101) may be configured to perform wireless charging using the antenna (220). Operation 1007 may substantially correspond to operation 807 of FIG. 8. The descriptions of operation 807 may be substantially applicable to operation 1007.
[0110] In operation 1009, the electronic device (101) may be configured to identify that the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a position different from the specified position.
[0111] According to one embodiment, when the accessory device (e.g., the accessory device (901) of FIG. 9) is not manufactured by the manufacturer of the electronic device (101) and / or an approved third-party manufacturer, when the accessory device (901) is coupled to the electronic device (101), the position of the magnet of the accessory device (901) may correspond to a position different from the designated position. In this case, since the area of the conductive portion (230) of the electronic device (101) that overlaps the magnet is not maximum, the capacitance value caused by the conductive portion (230) may be less than or equal to a second threshold value. At least one processor (120) may be configured to identify that the position of the magnet does not correspond to the designated position based on identifying a capacitance value less than or equal to the second threshold value.
[0112] In operation 1011, the electronic device (101) may be configured to provide a notification indicating the different location. Operation 1011 may substantially correspond to operation 811 of FIG. 8. Descriptions of operation 811 may be substantially applicable to operation 1011. For example, the electronic device (101) may provide a visual notification, an auditory notification, and / or a tactile notification.
[0113] Figure 11 illustrates the antenna and switch circuit of an electronic device.
[0114] Referring to FIG. 11, an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 2) may include a switch circuit (1110) and a matching circuit (1120).
[0115] For example, while the antenna (220) is receiving the power, a noise signal may be induced in a conductive part (230) placed around the antenna (220). The noise signal induced in the conductive part (230) may affect the power received by the antenna (220) and degrade the wireless charging efficiency. According to the magnetic power profile (MPP) defined in the Qi standard, an increased wireless charging operating frequency (e.g., about 360 kHz) may cause more noise signals. The noise signal may lower the total isotropic sensitivity (TIS) of the antenna (220) for wireless charging, thereby degrading the wireless charging efficiency.
[0116] According to one embodiment, the conductive portion (230) may be electrically connected to the ground (G) of the electronic device (101). For example, the conductive portion (230) may include one port. For example, a switch circuit (1110) may be configured to electrically connect the conductive portion (230) to the ground (G) of the electronic device (101). As the conductive portion (230) is electrically connected to the ground (G) of the electronic device (101), noise signals induced in the conductive portion (230) may be reduced by flowing to the ground (G). The ground (G) of the electronic device (101) may be referred to as a metal plate (e.g., a support member, a bracket) placed within the housing (210) or a ground layer of a printed circuit board electrically connected to said metal plate.
[0117] An electronic device (101) according to one embodiment may include a switch circuit (1110). The switch circuit (1110) may be configured to electrically connect a conductive portion (230) to the ground (G) of the electronic device (101).
[0118] According to one embodiment, the switch circuit (1110) may be configured to provide a first state in which the conductive portion (230) is electrically connected to at least one processor (e.g., at least one processor (120) of FIG. 3) or a second state in which the conductive portion (230) is electrically connected to ground (G). For example, the switch circuit (1110) may be a single pole double throw (SPDT) switch circuit. For example, the switch circuit (1110) may include a first terminal (1111) electrically connected to the conductive portion (230), a second terminal (1112) electrically connected to at least one processor (120), and a third terminal (1113) electrically connected to ground (G) of the electronic device (101). When the switch circuit (1110) is in the first state, the first terminal (1111) may be electrically connected to the second terminal (1112). When the switch circuit (1110) is in a second state, the first terminal (1111) can be electrically connected to the third terminal (1113). At least one processor (120) can be configured to control the switch circuit (1110).
[0119] According to one embodiment, at least one processor (120) may be configured to identify information between a magnet (e.g., magnet (320) of FIG. 2) of an accessory device (e.g., accessory device (301) of FIG. 2) and a conductive part (230) of an electronic device (101) within a first state of the switch circuit (1110). For example, within a first state of the switch circuit (1110) in which a first terminal (1111) is connected to a second terminal (1112), at least one processor (120) may be electrically connected to the conductive part (230). At least one processor (120) may identify said information by obtaining a change in VSWR, a capacitance value, and / or an inductance value caused by the interaction between the magnet (320) and the conductive part (230) within the first state of the switch circuit (1110). As described above, at least one processor (120) may be configured to identify, based on the information, whether the location of the magnet (320) for the electronic device (101) corresponds to a designated location. The electronic device (101) may include a matching circuit (1120) for impedance matching of a transmission line transmitting the information, which is positioned between the switch circuit (1110) and at least one processor (120).
[0120] According to one embodiment, at least one processor (120) may be configured to change the switch circuit (1110) to a second state based on identifying that the position of the magnet (320) corresponds to a designated position. For example, in the first state of the switch circuit (1110), at least one processor (120) electrically connected to the conductive part (230) may control the switch circuit (1110) so that the state of the switch circuit (1110) changes to a second state after identifying that the position of the magnet (320) corresponds to a designated position. As the switch circuit (1110) changes to the second state, the conductive part (230) may be electrically connected to the ground (G) of the electronic device (101). In the second state of the switch circuit (1110), noise signals induced into the conductive part (230) may be reduced through the ground (G). By reducing the above noise signal, the wireless charging efficiency of the electronic device (101) can be improved.
[0121] The default state of the switch circuit (1110) may be a first state. In the first state of the switch circuit (1110), at least one processor (120) may be electrically connected to the conductive part (230). When the accessory device (301) is coupled to the electronic device (101), at least one processor (120) electrically connected to the conductive part (230) via the switch circuit (1110) may be configured to use the conductive part (230) to identify whether the position of the magnet (320) corresponds to a designated position. Since the operation of determining whether the position of the magnet (320) corresponds to a designated position using the conductive part (230) does not need to be performed continuously, at least one processor (120) may change the state of the switch circuit (1110) to a second state after identifying the designated position. In the second state of the switch circuit (1110), as the conductive part (230) is electrically connected to ground (G), the wireless charging efficiency of the electronic device (101) can be improved.
[0122] Figure 12 illustrates the antenna and switch circuit of an electronic device.
[0123] Referring to FIG. 12, an electronic device (101) according to one embodiment may include a matching circuit (1220) and / or a noise canceling circuit (1210). For example, the conductive part (230) may include two ports (421, 422). The matching circuit (1220) and the noise canceling circuit (1210) may be configured to reduce a noise signal induced into the conductive part (230).
[0124] According to one embodiment, the matching circuit (1220) may include a passive component such as a capacitor or an inductor. The matching circuit (1220) may be electrically connected to the conductive part (230). The matching circuit (1220) may be used to reduce a noise signal induced into the conductive part (230). For example, at least one processor (e.g., at least one processor (120)) may be configured to identify the resonant frequency of the noise signal induced into the conductive part (230). At least one processor (120) may be configured to control the matching circuit (1220) based on the resonant frequency of the noise signal to reduce the noise signal. For example, at least one processor (120) may reduce the noise signal by adjusting the parameter value (e.g., capacitance or inductance) of the passive component of the matching circuit (1220) to block a signal of a frequency corresponding to the resonant frequency of the noise signal.
[0125] According to one embodiment, a noise canceling circuit (1210) may be used to cancel out a noise signal induced in a conductive part (230). The noise canceling circuit (1210) may be electrically connected to the conductive part (230) through a switch circuit (1230). For example, the switch circuit (1230) may be a DP4T (double pole four throw) switch circuit. For example, the switch circuit (1230) may include a first terminal (1231), a second terminal (1232), a third terminal (1233), a fourth terminal (1234), a fifth terminal (1235), and a sixth terminal (1236). The first terminal (1231) may be electrically connected to a second port (422) of the conductive part (230). The second terminal (1232) may be electrically connected to the first port (421) of the conductive portion (230). The third terminal (1233) may be electrically connected to at least one processor (120). The fourth terminal (1234) may be electrically connected to a noise canceling circuit (1210). The fifth terminal (1235) and the sixth terminal (1236) may be electrically connected to the ground (G) of the electronic device (101). According to one embodiment, the conductive portion (230) may be electrically connected to the ground (G) when the first terminal (1231) is electrically connected to either the fifth terminal (1235) or the sixth terminal (1236), and the second terminal (1232) is electrically connected to the other of the fifth terminal (1235) and the sixth terminal (1236).
[0126] According to one embodiment, at least one processor (120) may be electrically connected to a conductive part (230) through a switch circuit (1230). For example, when a first terminal (1231) and a third terminal (1233) are electrically connected, at least one processor (120) may be electrically connected to a conductive part (230) through a switch circuit (1230). At least one processor (120) may be configured to analyze the waveform of a noise signal induced into the conductive part (230) and to identify information regarding said waveform.
[0127] According to one embodiment, after identifying the information, at least one processor (120) may be configured to control a switch circuit (1230) so that the conductive part (230) and the noise canceling circuit (1210) are electrically connected. For example, when the second terminal (1232) and the fourth terminal (1234) are electrically connected, the noise canceling circuit (1210) may be electrically connected to the conductive part (230) through the switch circuit (1230). At least one processor (120) may be configured to control the noise canceling circuit (1210) based on the waveform of the noise signal induced into the conductive part (230). For example, a signal having a waveform with a phase opposite to the phase of the noise signal may be provided from the noise canceling circuit (1210) to the conductive part (230). The signal may substantially eliminate the noise signal by canceling out the noise signal. According to one embodiment, as the noise signal is canceled out, the wireless charging efficiency of the electronic device (101) can be improved.
[0128] Figure 13 illustrates the antenna and cable of an electronic device.
[0129] Referring to FIG. 13, an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 2) may include a cable (1310). For example, the cable (1310) may be referred to as a connecting member that transmits RF (radio frequency) signals. In FIG. 13, an accessory device (e.g., the accessory device (301) of FIG. 2) excluding the magnet (320) is omitted.
[0130] An electronic device (101) according to one embodiment may include a first printed circuit board and a second printed circuit board. For example, the second printed circuit board may be spaced apart from the first printed circuit board. For example, the first printed circuit board may be a main board, and the second printed circuit board may be a sub-board. At least one processor (120) may be placed on the first printed circuit board. A cable (1310) may be used for electrical connection between electronic components electrically connected to the first printed circuit board and electronic components electrically connected to the second printed circuit board. For example, RF signals received through another antenna electrically connected to the second printed circuit board may be provided to the first printed circuit board through the cable (1310). For example, RF signals provided from a wireless communication module (e.g., the wireless communication module (192) of FIG. 1) placed on a first printed circuit board to another antenna electrically connected to a second printed circuit board may be provided from the wireless communication module to the other antenna via a cable (1310). The cable (1310) may be referred to as a flexible printed circuit board (FPCB) or an FPCB RF cable (FRC).
[0131] Referring to FIG. 13, when the accessory device (301) is coupled to the electronic device (101), the cable (1310) may partially overlap the magnet (320) of the accessory device (301). As the cable (1310) partially overlaps the magnet (320), the magnetic field of the magnet (320) may affect the cable (1310). For example, a change in the VSWR of the transmission line may be caused by the interaction between the magnetic field of the magnet (320) and the transmission line of the cable (1310). When the position of the magnet (320) relative to the electronic device (101) corresponds to a specified position, the area of the cable (1310) overlapping the magnet (320) may be maximum. When the area of the cable (1310) overlapping the magnet (320) at the specified location is at its maximum, the amount of VSWR change caused by the cable (1310) may be at its maximum.
[0132] According to one embodiment, at least one processor (120) may be configured to identify a change in VSWR caused by a cable (1310) and, based on the change in VSWR, to identify whether the position of the magnet (320) of the accessory device (301) for the electronic device (101) corresponds to a designated position. The electronic device (101) may identify the designated position by using a cable (1310) that electrically connects the first printed circuit board and the second printed circuit board instead of a conductive part (230). The descriptions given above for the conductive part (230) may be applied substantially the same way to the cable (1310). For example, at least one processor (120) may be configured to compare the change in VSWR caused by the cable (1310) with a threshold value and, based on the change in VSWR that exceeds the threshold value, to identify whether the position of the magnet (320) corresponds to a designated position. At least one processor (120) may be configured to perform wireless charging based on identifying that the position of the magnet (320) corresponds to a designated position. At least one processor (120) may be configured to identify that the position of the magnet (320) corresponds to a position different from the designated position based on the VSWR change amount below a threshold value. At least one processor (120) may be configured to provide a notification based on identifying that the position of the magnet (320) does not correspond to a designated position. An electronic device (101) according to one embodiment can identify whether the position of the magnet (320) of the accessory device (301) corresponds to a designated position by omitting the Hall sensor and using a cable (1310) for electrical connection between printed circuit boards, so the internal arrangement structure of the electronic device (101) is simplified and the performance degradation of the electronic device (101) caused by a non-genuine accessory device (e.g., accessory device (901) of FIG. 9) can be reduced.
