Description

Technical Field

[0001] The present disclosure relates to an electronic device for providing a finding function of the electronic device in case the electronic device is lost and an operating method of the electronic device. Background Art

[0002] Due to the advancement of technology, various audio output devices that output audio based on data received through wireless communication have been developed. Among these audio output devices, a wearable device that can exchange data by connecting Bluetooth communication and an external electronic device (e.g., a smartphone, a tablet computer, a laptop computer, a PC, or a portable external electronic device) during short-range wireless communication and can configure left and right devices without wires can be called a true wireless stereo (TWS, totally wireless headphones).

[0003] The wearable electronic device may contain a micro coin battery inside, and a separate charging box may be provided to charge and store the battery. Since the wearable electronic device is a small device, the battery capacity is limited, and the wearable electronic device may be charged by installing a battery with a relatively large capacity in the charging box. Summary of the invention

[0004] On the other hand, since the wearable electronic device is a miniaturized product, the user is likely to lose it, and in the event of losing it, it is difficult to find the wearable electronic device.

[0005] Since the finding function of the wearable electronic device repeatedly transmits a radio frequency (RF) signal at regular time intervals, power consumption may be high.

[0006] The wearable electronic device must recharge the power consumed by continuously transmitting the RF signal to provide the finding function through the charging box, and thus the usage time including the charging box may be reduced. In addition, since the circuit configuration and the method of receiving power from the charging box can only be realized by the charger integrated circuit (IC), the conventional wearable electronic device can only operate when there is a battery inside the wearable electronic device.

[0007] Embodiments of the present disclosure can increase usage time by achieving a reduction in current consumption, and provide a circuit that is capable of providing a function that allows a user to find the location of a wearable electronic device (e.g., True Wireless Stereo (TWS)) if the wearable electronic device is lost while using the battery power of a charging box.

[0008] Objectives to be achieved in the present disclosure are not limited to the aforementioned objectives, and other objectives not described above may be apparently understood from the following description by a person having ordinary knowledge in the field to which the present disclosure pertains.

[0009] Additional aspects will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be understood by means of the examples presented.

[0010] A system according to an example embodiment may include: a first electronic device, a second electronic device and a charging box, wherein the first electronic device includes a first battery and a first processor; the second electronic device includes a second battery and a second processor; and the charging box includes a third battery, a boost circuit configured to charge the first electronic device and / or the second electronic device using power from the third battery, and a bypass circuit configured to supply power directly from the third battery to the first electronic device and / or the second electronic device, wherein the first processor of the first electronic device may be configured to: identify whether the first electronic device and / or the second electronic device is installed on the charging box; in response to the identification of being installed, identify the first battery and the third battery. The present invention relates to a charging box that detects the remaining battery capacity of a second battery, and determines the first electronic device with the larger remaining battery capacity as the main electronic device; sends a first request signal to the first external electronic device; in response to the strength of the first response signal received from the first external electronic device, switches to a lost mode to broadcast the first request signal at a specified period; and sends information related to the lost mode to the charging box, the second electronic device can be switched to a power saving mode in which the second electronic device does not perform operations other than specified functions, and the charging box can be configured to connect the third battery and the bypass circuit based on the information related to the lost mode, and use the bypass circuit to provide power of the third battery to the first electronic device.

[0011] A method for operating an electronic device system according to an example embodiment, wherein the electronic device system includes a first electronic device, a second electronic device and a charging box, the method may include: the first electronic device identifies whether the first electronic device and the second electronic device are installed on the charging box; the first electronic device identifies a first battery of the first electronic device and a second battery of the second electronic device in response to the identification of being installed, and determines the first electronic device with a larger battery level as a main electronic device; the first electronic device sends a first request signal to a first external electronic device; in response to a first response signal received from the first external electronic device being less than or equal to a specified value, the first electronic device switches to a lost mode to broadcast the first request signal at a specified period; the first electronic device sends information related to the lost mode to the charging box; the second electronic device switches to a power saving mode in which the second electronic device does not perform operations other than specified functions; and the charging box connects a third battery and the bypass circuit based on the information related to the lost mode, and uses the bypass circuit to provide power from the third battery to the first electronic device.

[0012] An electronic device according to an exemplary embodiment of the present disclosure may reduce power consumption when providing a search function.

[0013] The electronic device according to an example embodiment of the present disclosure may operate with low power in a lost mode, thereby extending a usage time.

[0014] The electronic device according to the example embodiment of the present disclosure may efficiently receive power by directly connecting the battery of the charging box to the electronic device via a bypass circuit.

[0015] In addition, various effects directly or indirectly recognized by the present disclosure can be provided. BRIEF DESCRIPTION OF THE DRAWINGS

According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, a memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connection terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a user identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the above components (e.g., the connection terminal 178) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101. In some embodiments, some of the above-described components (eg, sensor module 176, camera module 180, or antenna module 197) may be implemented as a single integrated component (eg, display module 160).

[0038] The processor 120 may run, for example, software (e.g., program 140) to control at least one other component (e.g., hardware component or software component) of the electronic device 101 connected to the processor 120, and may perform various data processing or calculations. According to one embodiment, as at least part of the data processing or calculation, the processor 120 may store a command or data received from another component (e.g., sensor module 176 or communication module 190) in the volatile memory 132, process the command or data stored in the volatile memory 132, and store the resultant data in the non-volatile memory 134. According to an embodiment, the processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)) or an auxiliary processor 123 (e.g., a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operationally independent or combined with the main processor 121. For example, when the electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or adapted to be dedicated to a specific function. The auxiliary processor 123 may be implemented separately from the main processor 121, or as part of the main processor 121.

[0039] When the main processor 121 is in an inactive (e.g., sleep) state, the auxiliary processor 123 (rather than the main processor 121) may control at least some of the functions or states related to at least one component among the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190), or when the main processor 121 is in an active state (e.g., running an application), the auxiliary processor 123 may control at least some of the functions or states related to at least one component among the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190) together with the main processor 121. According to an embodiment, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., a camera module 180 or a communication module 190) that is functionally related to the auxiliary processor 123. According to an embodiment, the auxiliary processor 123 (e.g., a neural processing unit) may include a hardware structure dedicated to artificial intelligence model processing.

[0053] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and supporting direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding 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, Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, a 5G network, a next-generation communication 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 these various types of communication modules can be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0054] The wireless communication module 192 can support 5G networks after 4G networks and next-generation communication technologies (e.g., new radio (NR) access technology).
