However, the present disclosure can be implemented in various forms and is not limited to the embodiments described herein. In conjunction with the description of the accompanying drawings, the same or similar reference numerals may be used for the same or similar components. In addition, for the sake of clarity and brevity, well-known functions and configurations may be omitted in the drawings and related descriptions.

Depending on the embodiment, the electronic device 101 can communicate with the electronic device 104 via the server 108. Depending on the embodiment, the electronic device 101 may include a processor 120, a memory 130, an input module 150, an audio 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 subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the aforementioned 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 ).

[0035] The processor 120 may execute, for example, software (e.g., program 140) to control at least one other component of the electronic device 101 connected to the processor 120 (e.g., a hardware component or a software component), 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 commands or data received from another component (e.g., sensor module 176 or communication module 190) in the volatile memory 132, process the commands or data stored in the volatile memory 132, and store the resulting data in the non-volatile memory 134. Depending on the 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 independent of or integrated 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 be 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.

[0036] When the main processor 121 is inactive (e.g., in a sleep state), the auxiliary processor 123 (rather than the main processor 121) may control at least some of the functions or states associated with at least one of the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190). Alternatively, when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 may work with the main processor 121 to control at least some of the functions or states associated with at least one of the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190).

[0043] The sensor module 176 can detect the operating state of the electronic device 101 (e.g., power or temperature) or the environmental state outside the electronic device 101 (e.g., the state of the user), and then generate an electrical signal or data value corresponding to the detected state. Depending on the embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illumination sensor.

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 support direct (e.g., wired) communication or wireless communication. Depending on the 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 may be implemented as a single component (e.g., a single chip), or may be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 may 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.

[0051] The wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (e.g., New Radio (NR) access technology). NR access technology can support enhanced mobile broadband (eMBB), massive machine type communication (mMTC), or ultra-reliable low-latency communication (URLLC). The wireless communication module 192 can support high-frequency bands (e.g., millimeter wave bands) to achieve, for example, high data transmission rates. The wireless communication module 192 can support various technologies for ensuring performance in high-frequency bands, such as, for example, beamforming, massive multiple-input multiple-output (massive MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. The wireless communication module 192 can support various requirements specified in the electronic device 101, an external electronic device (e.g., electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate for implementing eMBB (e.g., 20 Gbps or greater), loss coverage for implementing mMTC (e.g., 164 dB or less), or U-plane latency for implementing URLLC (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or 1 ms or less round trip).

Depending on the embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). Depending on the embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for the communication scheme used in a communication network (e.g., first network 198 or second network 199) may be selected from the multiple antennas 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 the external electronic device via the selected at least one antenna. Depending on the embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may also be formed as part of antenna module 197.

[0053] According to various embodiments, antenna module 197 may form a millimeter wave antenna module. According to embodiments, the millimeter wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and multiple antennas (e.g., array antennas). The RFIC is disposed on or adjacent to a first surface (e.g., the bottom surface) of the printed circuit board and is capable of supporting a designated high-frequency band (e.g., the millimeter wave band). The multiple antennas are disposed on or adjacent to a second surface (e.g., the top surface or a side surface) of the printed circuit board and are capable of transmitting or receiving signals in the designated high-frequency band.

[0054] At least some of the above components may be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transfer signals (e.g., commands or data) therebetween.

[0055] According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199. Each of the electronic device 102 or the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type than the electronic device 101. According to an embodiment, all or some operations to be executed on the electronic device 101 may be executed on one or more of the external electronic device 102, the external electronic device 104, or the server 108. For example, if the electronic device 101 should automatically execute a function or service or should execute a function or service in response to a request from a user or another device, the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service instead of executing the function or service, or the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service in addition to executing the function or service. The one or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or execute another function or service related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 may provide the result as at least a partial response to the request, either with or without further processing the result. To this end, for example, cloud computing technology, distributed computing technology, mobile edge computing (MEC) technology, or a client may be used.

The second housing structure 310 is configured to serve as a lid for the first housing structure 305, and the hinge structure is configured to rotatably connect the first housing structure 305 and the second housing structure 310. For example, when the second housing structure 310 is opened at a predetermined angle relative to the first housing structure 305, one side of the first housing structure 305 can be connected to one side of the second housing structure 310 via the hinge structure 420.

[0078] According to the embodiment, reference numerals <450> A printed circuit board (PCB) 455 and an FM radio receiving coil antenna 460 are shown disposed within the interior space of the first housing structure 305 as viewed from the top of the electronic device 210 .

[0079] In an embodiment, the printed circuit board 455 may be placed in the interior space of the first housing structure 305 of the electronic device 210. In an embodiment, the FM radio reception coil antenna 460 may be implemented in a specific pattern on the printed circuit board 455. This is not limited thereto, and the FM radio reception coil antenna 460 may also be implemented using a separate flexible printed circuit board (FPCB).

[0080] In embodiments, when the FM radio reception coil antenna 460 is implemented in a specific pattern on the printed circuit board 455, the FM radio reception coil antenna 460 may be disposed in at least a portion of one surface (e.g., the surface facing the z-axis direction) of the printed circuit board 455. In embodiments, the FM radio reception coil antenna 460 may have an axis substantially parallel to a first direction (e.g., the z-axis direction) (or a second direction (e.g., the −z-axis direction opposite to the z-axis direction)) and may include a planar (or spiral) coil wound at least once around the axis to have one or more patterns.

[0081] In an embodiment, the FM radio receive coil antenna 460 may have a first opening 470 having a first designated inner diameter configured about an axis.

[0082] In an embodiment, the printed circuit board 455 may also have (or include) a processor, a memory, and / or an interface disposed thereon.

[0083] In an embodiment, a feeding unit (feeding point) 465 may be provided on at least a portion of the printed circuit board 455. The FM radio reception coil antenna 460 may be fed by the feeding unit 465 based on a control signal transmitted by the electronic device 210 and / or a wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230). Based on the FM radio reception circuit 610 being powered by the feeding unit 465, the resonant frequency of the FM radio reception coil antenna 460 may be adjusted, and the FM radio reception coil antenna 460 may receive an FM radio signal corresponding to the resonant frequency of the FM radio channel.

[0084] Figure 5 The printed circuit board 455 , the FM radio reception coil antenna 460 , the wireless charging coil antenna 515 , and / or the shielding sheet 520 are shown arranged in the internal space of the electronic device 210 according to an embodiment of the present disclosure.

[0085] Reference Figure 5 , reference number <510> The printed circuit board 455, the FM radio receiving coil antenna 460, the wireless charging coil antenna 515 and / or the shielding sheet 520 are shown as being arranged in the internal space of the electronic device 210 when viewed in the z-axis direction. <550> A laminated structure of the printed circuit board 455 , the FM radio reception coil antenna 460 , the wireless charging coil antenna 515 , and / or the shielding sheet 520 arranged in the internal space of the electronic device 210 is shown.

[0086] In an embodiment, a printed circuit board 455 may be disposed within the interior space of the first housing structure 305 of the electronic device 210. The FM radio reception coil antenna 460 may be disposed on at least a portion of one surface (e.g., a surface facing the -z-axis direction) of the printed circuit board 455. The present disclosure is not limited thereto, and the FM radio reception coil antenna 460 may also be disposed on at least a portion of another surface (e.g., a surface facing the z-axis direction, which is a direction opposite to the -z-axis direction) of the printed circuit board 455.

[0087] In an embodiment, in the internal space of the first housing structure 305 of the electronic device 210 , the printed circuit board 455 , the FM radio reception coil antenna 460 , the shielding sheet 520 and / or the wireless charging coil antenna 515 may be sequentially stacked and arranged in the −z-axis direction.

[0088] In an embodiment, the shielding sheet 520 may be laminated to one surface of the wireless charging coil antenna 515 (eg, a surface facing the z-axis direction), and the FM radio receiving coil antenna 460 may be disposed on the shielding sheet 520 (eg, in the z-axis direction).

[0089] In embodiments, the FM radio reception coil antenna 460 may be configured in a specific pattern on at least a portion of one surface (e.g., a surface facing the -z-axis direction) of the printed circuit board 455. For example, the FM radio reception coil antenna 460 may have an axis substantially parallel to the z-axis direction (or the -z-axis direction) and may include a planar (or spiral) coil wound at least once around the axis to have one or more patterns.

[0090] In an embodiment, the wireless charging coil antenna 515 may have an axis substantially parallel to the z-axis (or -z-axis) and may include a planar (or spiral) coil wound at least once around the axis to form one or more patterns. The wireless charging coil antenna 515 may have a second opening 535 having a second designated inner diameter configured around the axis.

[0091] In an embodiment, when the FM radio reception coil antenna 460 is disposed to overlap with the wireless charging coil antenna 515, the FM radio reception coil antenna 460 may include a first opening 470 configured to correspond to the second opening 535 of the wireless charging coil antenna 515. In an embodiment, the second designated inner diameter of the second opening 535 of the wireless charging coil antenna 515 may be equal to the first designated inner diameter of the first opening 470 of the FM radio reception coil antenna 460. However, the present disclosure is not limited thereto.

[0092] In an embodiment, when wirelessly charging the electronic device 210, since the FM radio receiving coil antenna 460 includes the first opening 470 and the wireless charging coil antenna 515 includes the second opening 535, magnetic flux generated during wireless charging can pass through the first opening 470 and the second opening 535, thereby reducing mutual interference between the FM radio receiving coil antenna 460 and the wireless charging coil antenna 515.

[0093] In an embodiment, the shielding sheet 520 (or shielding tape) disposed between the FM radio receiving coil antenna 460 and the wireless charging coil antenna 515 may include a protective film and / or a graphite sheet. However, the present disclosure is not limited thereto. The shielding sheet 520 according to an embodiment can block (e.g., shield) the effects of noise generated by the operating frequency and / or electromagnetic signals transmitted or received by the wireless charging coil antenna 515 on components arranged in the z-axis direction. Furthermore, the shielding sheet 520 can focus and transmit signals (e.g., electromagnetic signals) transmitted from the wireless charging coil antenna 515 in a specific direction (e.g., the −z-axis direction, which is the direction of externally transmitted signals from the electronic device 210). As a result, the charging efficiency of the wireless charging coil antenna 515 can be improved.

[0094] While the FM radio reception coil antenna 460 has been described as being implemented on the printed circuit board (PCB) 455 in a specific pattern according to an embodiment, this is not limited to this. For example, the FM radio reception coil antenna 460 may also be implemented using a separate PCB. In this case, since the FM radio reception coil antenna 460 is positioned at a specified distance from the wireless charging coil antenna 515, with the PCB 455 interposed between them, the shielding sheet 520 may be omitted. For example, when the FM radio reception coil antenna 460 and the wireless charging coil antenna 515 are positioned with the PCB 455 interposed therebetween, reception of FM radio signals using the FM radio reception coil antenna 460 is unaffected by noise generated by the operating frequency and / or electromagnetic signals transmitted or received via the wireless charging coil antenna 515. Therefore, the shielding sheet 520 may be omitted. However, this is not a limitation.

[0095] In an embodiment, the shielding sheet 520 may include an area substantially equal to the pattern area of ​​the wireless charging coil antenna 515. For example, the shielding sheet 520 may have a shape corresponding to the pattern of the wireless charging coil antenna 515. However, the present disclosure is not limited thereto. In an embodiment, the shielding sheet 520 may have a third opening (not shown) having a third designated inner diameter configured about an axis substantially parallel to the z-axis direction (or the −z-axis direction). For example, the shielding sheet 520 may have a third opening (not shown) configured to correspond to the second opening 535 of the wireless charging coil antenna 515 when the shielding sheet 520 is arranged to overlap the FM radio receiving coil antenna 460 and the wireless charging coil antenna 515. For example, the third designated inner diameter of the third opening of the shielding sheet 520 may be configured (or varied) based on the efficiency of the FM radio receiving coil antenna 460 and the efficiency of the wireless charging coil antenna 515 (e.g., wireless charging efficiency) to reduce mutual interference between the FM radio receiving coil antenna 460 and the wireless charging coil antenna 515.

[0096] In an embodiment, the third designated inner diameter of the third opening of the shielding sheet 520 may be equal to or greater than the first designated inner diameter of the first opening 470 of the FM radio receiving antenna 460 and / or the second designated inner diameter of the second opening 535 of the wireless charging coil antenna 515. In an embodiment, when wirelessly charging the electronic device 210, power may be applied to the AC input terminals 525, 530 via a power transmission device (e.g., a wireless charging pad, a tablet, or a smartphone), and the battery of the electronic device 210 (e.g., Figure 6 The battery 635 may be charged based on current flowing through the wireless charging coil antenna 515 due to power applied to the AC input terminals 525 , 530 .

[0101] In an embodiment, the electronic device 210 may transmit the FM radio signal received via the FM radio receiving circuit 610 to the first wireless audio device 220 and / or the second wireless audio device 230 via the short-range communication circuit 605 .

[0102] According to an embodiment of the present disclosure, the FM radio receiving circuit 610 may receive the FM radio signal via an antenna (e.g., Figure 4 The FM radio receiving coil antenna 460 receives an FM radio signal corresponding to an FM radio broadcast. The FM radio signal received by the FM radio receiving circuit 610 may be implemented as an analog signal. The FM radio receiving coil antenna 460 may be connected to the FM radio via a feeding unit (e.g., a power supply unit) provided on at least a portion of the printed circuit board 455 based on the control of the processor 645. Figure 4 The processor 645 is fed by the feeding unit 465 of the electronic device 210 and operates according to control signals transmitted by the electronic device 210 and / or wireless audio devices (e.g., the first wireless audio device 220 and / or the second wireless audio device 230). Based on the FM radio reception coil antenna 460 being fed by the feeding unit 465, the resonant frequency of the FM radio reception coil antenna 460 can be adjusted, thereby allowing the FM radio reception circuit 610 to receive FM radio signals corresponding to various FM radio channels.

[0103] In an embodiment, the FM radio reception circuit 610 may process the received FM radio signal and transmit the processed signal to the processor 645. The FM radio reception circuit 610 may include an analog-to-digital converter (ADC) that converts the FM radio signal implemented in analog form into a digital form that can be processed by the processor 645. The FM radio reception circuit 610 may transmit the signal converted into digital form to the processor 645.

The memory 615 may store various instructions executable by the processor 645.

[0105] According to an embodiment, under the control of the processor 645, the memory 615 may store instructions for identifying whether a wireless audio device (e.g., the first wireless audio device 220 and the second wireless audio device 230) is worn in the user's ear based on sensor information received from the wireless audio device. Under the control of the processor 645, the memory 615 may also store instructions for the processor 645 to enable the FM radio reception circuit 610 upon detecting an input for enabling the FM radio reception function. Under the control of the processor 645, the memory 615 may also store instructions for transmitting FM radio signals received by the enabled FM radio reception circuit 610 to at least one of the first wireless audio device 220 and the second wireless audio device 230 via the short-range communication circuit 605. Under the control of the processor 645, the memory 615 may also store instructions for outputting FM radio signals received by the FM radio reception circuit 610 via the speaker 620. When the electronic device 210 does not include the short-range communication circuit 605 and the speaker 620, under the control of the processor 645, the memory 615 may store instructions for transmitting an FM radio signal via a wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) installed in the electronic device 210 to another wireless audio device (e.g., the second wireless audio device 230 or the first wireless audio device 220), and the FM radio signal is received via the FM radio receiving circuit 610.

[0106] According to an embodiment of the present disclosure, under the control of the processor 645, the speaker 620 (eg, Figure 3 The speaker 330 of the FM radio receiving circuit 610 may output a sound corresponding to the FM radio signal received from the FM radio receiving circuit 610 .

[0107] According to an embodiment of the present disclosure, the sensor circuit 625 may include a Hall sensor (not shown) using magnetism. The Hall sensor may detect the cover of the electronic device 210 (eg, Figure 3 The Hall sensor may transmit a sensor signal indicating the detected open state and / or closed state of the cover of the electronic device 210 to the processor 645 .

[0108] According to an embodiment of the present disclosure, the input circuit 630 may include at least one button for controlling other electronic devices (e.g., the first wireless audio device 220, the second wireless audio device 230, and / or the external electronic device 240) communicatively connected via the short-range communication circuit 605 (e.g., controlling the operation of the first wireless audio device 220 and / or the second wireless audio device 230 to output audio signals or FM radio signals, or controlling the communication connection of the external electronic device 240). For example, the at least one button may be implemented as a pressure sensor or a touch sensor, but is not limited thereto.

[0109] According to an embodiment of the present disclosure, the battery 635 may power a wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230) and / or at least one component of the electronic device 210. In an embodiment, the battery 635 may include a non-rechargeable primary battery, a rechargeable secondary battery, and / or a fuel cell.

[0110] According to an embodiment of the present disclosure, the interface 640 may support one or more designated protocols that can be used to connect the electronic device 210 directly or wirelessly to a wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230) and / or an external electronic device 240. For example, the interface 640 may include an inter-chip sound (I2S) interface and / or an inter-integrated circuit (I2C) interface. Under the control of the processor 645, the I2S interface may transmit FM radio signals received via the FM radio receiving circuit 610 to the speaker 620. Under the control of the processor 645, the I2C interface may transmit control signals related to the FM radio signals to the FM radio receiving circuit 610 and / or the speaker 620. For example, control signals associated with FM radio signals may include, but are not limited to, control signals associated with changing FM radio channels, control signals associated with searching for FM radio channels, control signals associated with adjusting the volume of FM radio signals, control signals associated with software resets, and / or control signals for processing FM radio signals (such as gain adjustment).

[0111] According to an embodiment of the present disclosure, the power line communication (PLC) circuit 643 may support a communication channel between the electronic device 210 and a wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230). For example, based on at least one terminal (not shown) included in the wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230) and a first housing structure (e.g., Figure 3 The first housing 305) has a first groove (eg, Figure 3 ) and a second groove (eg, Figure 3 at least one terminal (eg, Figure 3 The PLC circuit 643 may support a communication channel implemented as power line communication (PLC) by using physical contact between at least one terminal 345 of the electronic device 210, and using an electrical path generated when a wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230) is electrically connected to the electronic device 210.

[0112] According to an embodiment of the present disclosure, the processor 645 can be operably connected to various electronic components included in the electronic device 210 (for example, the short-range communication circuit 605, the FM radio reception circuit 610, the memory 615, the speaker 620, the sensor circuit 625, the input circuit 630, the battery 635, the interface 640 and / or the PLC circuit 643), and can control the various components operably connected to the processor 645.

[0113] In an embodiment, while at least one of the first wireless audio device 220 and the second wireless audio device 230 is worn in the user's ear, the processor 645 may detect an input for enabling the FM radio reception function. For example, the input for enabling the FM radio reception function may include: Figure 3 The present invention also includes the operation of a physical button (e.g., a key button) on the first housing structure 305 and / or the second housing structure 310), a touch input detected via a touch sensor provided on the housing structure 305 and / or 310, a voice input related to the activation of the FM radio reception function, a wireless signal related to the activation of the FM radio reception function (e.g., via an input circuit (e.g., provided separately in the wireless audio device)), and a wireless signal (e.g., a key button) provided on the first housing structure 305 and / or the second housing structure 310). Figure 7 The present invention also relates to a wireless signal related to the operation of the FM radio reception function and detected by the input circuit 720 of the external electronic device 240), or a wireless signal related to the activation of the FM radio reception function and received from the external electronic device 240 (a wireless signal input for activating the FM radio reception function in an application related to the FM radio reception function and running on the external electronic device 240).

[0114] In an embodiment, upon detecting an input for enabling an FM radio reception function, the processor 645 may enable the FM radio reception circuit 610 and receive an FM radio signal via the FM radio reception circuit 610. The processor 645 may transmit the FM radio signal received via the FM radio reception circuit 610 to at least one of the first wireless audio device 220 and the second wireless audio device 230 via the short-range communication circuit 605, causing at least one of the first wireless audio device 220 and the second wireless audio device 230 to output the FM radio signal.

[0115] In an embodiment, the processor 645 may transmit an FM radio signal received via the FM radio reception circuit 610 to the speaker 620 via the interface 640 (e.g., an inter-integrated chip sound (I2S) interface), thereby outputting the FM radio signal via the speaker 620. The processor 645 may send control signals related to the FM radio signal (e.g., a control signal associated with changing an FM radio channel, a control signal associated with searching for an FM radio channel, a control signal associated with adjusting the volume of the FM radio signal, a control signal associated with a software reset, and / or a control signal for processing the FM radio signal (e.g., gain adjustment)) to the FM radio reception circuit 610 and / or the speaker 620 via the interface 640 (e.g., an inter-integrated circuit (I2C) interface).

[0116] In an embodiment, when an input for outputting an FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 is detected, the processor 645 may transmit the FM radio signal to at least one of the first wireless audio device 220 and the second wireless audio device 230, so that at least one of the first wireless audio device 220 and the second wireless audio device 230 outputs the FM radio signal received from the FM radio receiving circuit 610.

[0176] In an embodiment, in operation 930, the first wireless audio device 220 may receive a signal via a speaker (eg, Figure 7 The speaker 730 of the second wireless audio device 230 outputs the FM radio signal received from the electronic device 210. In operation 935, the second wireless audio device 230 may output the FM radio signal received from the electronic device 210 via the speaker 730.

[0177] Although references according to various embodiments have been provided on the assumption that both the first wireless audio device 220 and the second wireless audio device 230 are worn in the user's ears, Figure 9 , but only one of the first wireless audio device 220 and the second wireless audio device 230 may be worn.

[0178] For example, when it is recognized that only the first wireless audio device 220 is worn in the left ear of the user, Figure 9 Operations 925 and 935 may be omitted. In this case, the electronic device 210 may transmit the FM radio signal received via the FM radio receiving circuit 610 only to the first wireless audio device 220 worn in the user's left ear. The first wireless audio device 220 may output the FM radio signal received from the electronic device 210 via the speaker 730.

[0179] In another example, when it is recognized that only the second wireless audio device 230 is worn in the right ear of the user, Figure 9Operations 920 and 930 may be omitted. In this case, the electronic device 210 may transmit the FM radio signal received by the FM radio receiving circuit 610 only to the second wireless audio device 230 worn in the user's right ear. The second wireless audio device 230 may output the FM radio signal received from the electronic device 210 via the speaker 730.

[0180] According to various embodiments, while at least one of the first wireless audio device 220 and the second wireless audio device 230 is being worn in a user's ear and is outputting an audio signal received from an external electronic device (e.g., external electronic device 240 in FIG. 2 ), an input for enabling an FM radio reception function may be detected. In this case, the first wireless audio device 220 and / or the second wireless audio device 230 may stop outputting the audio signal received from the external electronic device 240 and instead output the FM radio signal received from the electronic device 210. However, this is not limited to this. The external electronic device 240 may output information related to the output of the FM radio signal. For example, this information may include information for enabling the FM radio reception circuit 610 of the electronic device 210 and information for determining whether to output the FM radio signal received via the FM radio reception circuit 610 of the electronic device 210. However, this is not limited to this. According to embodiments, upon detecting an input related to the output of an FM radio signal, the external electronic device 240 may transmit the input to the electronic device 210. Based on input related to the output of the FM radio signal received from the external electronic device 240, the electronic device 210 may enable the FM radio reception circuit 610 and transmit the FM radio signal received via the FM radio reception circuit 610 to the wireless audio device worn in the user's ear (e.g., the first wireless audio device 220 and / or the second wireless audio device 230).

[0181] Figure 10 is a flowchart illustrating a method of outputting an FM radio signal of the electronic device 210 according to an embodiment of the present disclosure.

[0182] In the following embodiments, the various operations may be performed sequentially, but need not be performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0183] According to an embodiment, operations 1005 to 1025 may be understood as being performed by an electronic device (eg, Figure 6 The processor of the electronic device 210 (eg, Figure 6 Processor 645) executes.

[0184] exist Figure 10 According to various embodiments, the electronic device 210 may include a speaker (eg, Figure 6 The FM radio signal may be output via the speaker 620. In this regard, further details will be described in the following description.

[0185] In an embodiment, before performing operation 1005 described below, the first wireless audio device (e.g., the first wireless audio device 220 of FIG. 2 ) and / or the second wireless audio device (e.g., the second wireless audio device 230 of FIG. 2 ) may be installed in the electronic device 210, or may be separated from the electronic device 210 and worn in the user's ear. Alternatively, the first wireless audio device 220 and the second wireless audio device 230 may be paired with an external electronic device (e.g., the external electronic device 240 of FIG. 2 ) while being worn in the user's ear, and may output audio signals received from the external electronic device 240.

[0186] In an embodiment, in operation 1005, the processor 645 may enable the FM radio reception circuit (eg, Figure 6 For example, the input for enabling the FM radio reception function may include a housing structure provided on the electronic device 210 (eg, Figure 3 The present invention also includes the operation of a physical button (e.g., a key button) on the first housing structure 305 and / or the second housing structure 310), a touch input detected via a touch sensor provided on the housing structure 305 and / or 310, a voice input related to the activation of the FM radio reception function, a wireless signal related to the activation of the FM radio reception function (e.g., via an input circuit (e.g., provided separately in the wireless audio device)), and a wireless signal (e.g., a key button) provided on the first housing structure 305 and / or the second housing structure 310). Figure 7 The present invention also provides a wireless signal related to the operation of the FM radio reception function and detected by the input circuit 720 of the external electronic device 240), or a wireless signal related to the activation of the FM radio reception function and received from the external electronic device 240 (generated in response to an input for activating the FM radio reception function in an application related to the FM radio reception function and running on the external electronic device 240).

[0187] In an embodiment, in operation 1010, the processor 645 may receive an FM radio signal via the FM radio reception circuit 610. In an embodiment, in operation 1015, the processor 645 may output the received FM radio signal via the speaker 620.

[0188] In an embodiment, the processor 645 may communicate with the user via an interface (e.g., Figure 6 The interface 640 (eg, an integrated inter-chip sound (I2S) interface) transmits the FM radio signal received via the FM radio reception circuit 610 to the speaker 620 , and outputs the FM radio signal via the speaker 620 .

[0189] In an embodiment, the processor 645 may transmit control signals related to FM radio signals to the FM radio receiving circuit 610 and / or the speaker 620 via the interface 640 (e.g., an inter-integrated circuit (I2C) interface). For example, the control signals related to the FM radio signals may include a control signal for changing the FM radio channel, a control signal for searching for an FM radio channel, a control signal for adjusting the volume of the FM radio signal, a control signal related to software reset, and / or a control signal for processing the FM radio signal (such as gain adjustment). However, this is not limited thereto.

[0190] In an embodiment, in operation 1020 , the processor 645 may identify whether an input for outputting an FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 is detected.

[0191] In an embodiment, when the first wireless audio device 220 and the second wireless audio device 230 are installed in the electronic device 210, the input for outputting the FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 may include an input for switching to a state in which the first wireless audio device 220 and the second wireless audio device 230 are separated from the electronic device 210.

[0192] In an embodiment, when the first wireless audio device 220 and the second wireless audio device 230 are separated from the electronic device 210 and worn in the user's ears, or when the first wireless audio device 220 and the second wireless audio device 230 are outputting an audio signal received from the external electronic device 240, the input for outputting the FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 may include: inputting the FM radio signal via an input circuit (e.g., Figure 7 The input circuit 720 (eg, a touch panel) of the electronic device 210 detects an input for outputting an FM radio signal, the input circuit 720 (eg, a touch panel) of the electronic device 210 detects an input for outputting an FM radio signal ... Figure 3 the first housing structure and / or the second housing structure), a touch input detected via the touch sensor, a voice input related to activation of the FM radio reception function, a wireless signal related to activation of the FM radio reception function (for example, an input signal received via an input circuit separately provided in the wireless audio device (for example, Figure 7The present invention may include a wireless signal related to an operation detected by the input circuit 720 of the external electronic device 240), or a wireless signal related to the activation of the FM radio reception function and received from the external electronic device 240 (for example, a wireless signal corresponding to an input for activating the FM radio reception function in an application related to the FM radio reception function and running on the external electronic device 240).

[0193] In an embodiment, when an input for outputting an FM radio signal is received via the input circuit 720 (e.g., a touch panel) included in the first wireless audio device 220 and / or the second wireless audio device 230, the first wireless audio device 220 and / or the second wireless audio device 230 may transmit information indicating that the input for outputting an FM radio signal has been received to the electronic device 210 via the short-range communication circuit 705.

[0194] In an embodiment, when a wireless signal related to activation of the FM radio reception function is received from the external electronic device 240 (e.g., a wireless signal corresponding to an input for activating the FM radio reception function in an application related to the FM radio reception function and running on the external electronic device 240), the external electronic device 240 may communicate with the external electronic device 240 via a short-range communication circuit (e.g., Figure 1 The wireless communication module 192 of the electronic device 210 sends information to the electronic device 210, the information indicating that an input for outputting an FM radio signal has been received.

[0195] In an embodiment, when an input for outputting an FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 is detected (e.g., “Yes” in operation 1020 ), in operation 1025 , the processor 645 may transmit the FM radio signal to at least one of the first wireless audio device 220 and the second wireless audio device 230 .

[0196] In an embodiment, when an input for outputting an FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 is detected, the processor 645 may transmit the FM radio signal to the first wireless audio device 220 and / or the second wireless audio device 230 via the short-range communication circuit 605 instead of transmitting it to the speaker 620, and the FM radio signal is received via the FM radio receiving circuit 610.

[0197] This is not limited to this, and when an input for outputting an FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 is detected, the processor 645 may transmit the FM radio signal received via the FM radio receiving circuit 610 to the speaker 620, and further to the first wireless audio device 220 and the second wireless audio device 230. In this case, the FM radio signal can be output not only via the speaker 620, but also via the first wireless audio device 220 and the second wireless audio device 230.

[0198] In an embodiment, when an input for outputting an FM radio signal via the first wireless audio device 220 (or the second wireless audio device 230) is detected while an audio signal received from the external electronic device 240 is being output via both the first wireless audio device 220 and the second wireless audio device 230, the processor 645 may transmit the FM radio signal only to the first wireless audio device 220 (or the second wireless audio device 230) via the short-range communication circuit 605. In this case, the first wireless audio device 220 (or the second wireless audio device 230) may output the FM radio signal received from the electronic device 210 instead of the audio signal received from the external electronic device 240. The second wireless audio device 230 (or the first wireless audio device 220) may continue to output the audio signal received from the external electronic device 240.

[0199] In an embodiment, when an input for outputting an FM radio signal via one of the first wireless audio device 220, the second wireless audio device 230, the electronic device 210, and the external electronic device 240 is not detected (e.g., “No” in operation 1020), the processor 645 may branch to operation 1010 and repeatedly perform operations 1010 to 1020.

[0200] Figure 11 A signal flow between the electronic device 210 , the first wireless audio device 220 , and the second wireless audio device 230 according to an embodiment of the present disclosure is shown.

[0201] In the following embodiments, the various operations may be performed sequentially, but need not be performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0202] According to an embodiment, operations 1105 to 1130 may be understood as being executed by a processor (eg, Figure 6 Operation 1135 may be understood as being performed by a processor (eg, a processor of the first wireless audio device (eg, the first wireless audio device 220 of FIG. 2 ) Figure 7Operation 1140 may be understood to be performed by the processor 745 of the second wireless audio device (eg, the second wireless audio device 230 of FIG. 2 ).

[0203] Since according to various embodiments Figure 11 Operations 1105 to 1130 are the same as those described above. Figure 10 Operations 1005 to 1125 are substantially the same, so their detailed descriptions are available Figure 10 Description instead.

[0204] Reference Figure 11 In operation 1105, when the electronic device 210 detects an input for enabling the FM radio reception function, in operation 1110, the electronic device 210 may enable the FM radio reception circuit (eg, Figure 6 In operation 1115, the electronic device 210 may receive an FM radio signal via the FM radio receiving circuit 610 and transmit the signal to the FM radio receiver via a speaker (eg, Figure 6 For example, the electronic device 210 may output the received FM radio signal via an interface (eg, Figure 6 The interface 640 (eg, an integrated inter-chip sound (I2S) interface) transmits the FM radio signal received via the FM radio reception circuit 610 to the speaker 620 , and outputs the FM radio signal via the speaker 620 .

[0205] In an embodiment, the electronic device 210 may receive (or detect) a control signal related to an FM radio signal and may transmit the control signal related to the FM radio signal to the FM radio receiving circuit 610 and / or the speaker 620 via an interface 640 (e.g., an inter-integrated circuit (I2C) interface). For example, the control signal related to the FM radio signal may include a control signal for changing an FM radio channel, a control signal for searching for an FM radio channel, a control signal for adjusting the volume of the FM radio signal, a control signal related to a software reset, and / or a control signal for processing the FM radio signal (e.g., gain adjustment). However, the present invention is not limited thereto.

[0206] In an embodiment, in operation 1120 , the electronic device 210 may identify whether an input for outputting an FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 is detected.

[0207] Reference according to an embodiment is provided on the assumption that an input for outputting an FM radio signal via the first wireless audio device 220 and the second wireless audio device 230 is detected. Figure 11 Description.

[0208] In an embodiment, when an input for outputting an FM radio signal via at least one of the first wireless audio device 220 and the second wireless audio device 230 is detected (e.g., “Yes” in operation 1120), in operation 1125, the electronic device 210 may output an FM radio signal via a short-range communication circuit (e.g., Figure 6 The short-range communication circuit 605 of the first wireless audio device 220 transmits the FM radio signal to the first wireless audio device 220, and in operation 1130, transmits the FM radio signal to the second wireless audio device 230 via the short-range communication circuit 605. In operation 1135, the first wireless audio device 220 may transmit the FM radio signal to the second wireless audio device 230 via the speaker (e.g., Figure 7 The second wireless audio device 230 may output the FM radio signal received from the electronic device 210 via the speaker 730 in operation 1140 .

[0209] The reference signals according to various embodiments have been described on the assumption that an input for outputting an FM radio signal via both the first wireless audio device 220 and the second wireless audio device 230 is detected. Figure 11 However, this is not limited to this. For example, in the first wireless audio device 220 and the second wireless audio device 230, an input for outputting an FM radio signal via the first wireless audio device 220 or the second wireless audio device 230 may also be detected. In this case, the electronic device 210 may transmit the FM radio signal to the first wireless audio device 220 or the second wireless audio device 230 that has detected the input for outputting the FM radio signal.

[0210] References according to various embodiments have been provided under the following assumptions Figures 8 to 11 When the electronic device 210 includes the short-range communication circuit 605 and the speaker 620, the electronic device 210 may transmit an FM radio signal to the first wireless audio device 220 and / or the second wireless audio device 230 via the short-range communication circuit 605 so that the FM radio signal is output via the first wireless audio device 220 and / or the second wireless audio device 230, or transmit an FM radio signal to the speaker 620 so that the FM radio signal is output via the speaker 620. However, this is not limited thereto.

[0211] For example, the electronic device 210 may not include the short-range communication circuit 605 and the speaker 620. Figures 12 to 14b Various embodiments of a method of outputting an FM radio signal via the first wireless audio device 220 or the second wireless audio device 230 when the electronic device 210 does not include the short-range communication circuit 605 and the speaker 620 are described.

[0212] Figure 12 A method of outputting an FM radio signal of the electronic device 210 according to an embodiment of the present disclosure is illustrated.

[0213] Reference Figure 12 , as shown in reference number <1210> As shown, the first wireless audio device 220 and the second wireless audio device 230 can be detached from the electronic device 210. For example, the first wireless audio device 220 and the second wireless audio device 230 can be detached from the electronic device 210 and worn in both ears of the user. For example, the first wireless audio device 220 and the second wireless audio device 230 can be worn in both ears of the user and output audio signals received from an external electronic device (e.g., external electronic device 240 in FIG. 2 ) (e.g., audio signals according to an incoming call, a received message, an alarm, or audio playback). However, this is not limited to this.

[0214] In an embodiment, while the first wireless audio device 220 and the second wireless audio device 230 are outputting audio signals received from the external electronic device 240, the external electronic device 240 may detect an input for enabling the FM radio reception function. For example, the external electronic device 240 may execute an application related to the radio reception function in response to a user input, and may detect the input for enabling the FM radio reception function via the executed application related to the FM radio reception function. Based on the detection of the input for enabling the FM radio reception function, the external electronic device 240 may guide one of the first wireless audio device 220 and the second wireless audio device 230 to a placement state in the electronic device 210. For example, the external electronic device 240 may output placement-related guidance information to a display (e.g., Figure 1 The external electronic device 240 may transmit the installation-related guidance information to the wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230) so that one of the first wireless audio device 220 and the second wireless audio device 230 worn in the user's ear is installed in the electronic device 210, thereby emitting the sound through the speaker (e.g., the speaker) of the wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230). Figure 7 The speaker 730) outputs placement-related guidance information.

[0215] In an embodiment, when at least one of the first wireless audio device 220 and the second wireless audio device 230 is installed in the electronic device 210, the electronic device 210 may transmit the FM radio signal received via the FM radio receiving circuit 610 to the wireless audio device installed in the electronic device 210. For example, the wireless audio devices (e.g., the first wireless audio device 220 and the second wireless audio device 230) may include at least one terminal, and the electronic device 210 may further include at least one terminal (e.g., Figure 3 At least one terminal 345). Based on the wireless audio device (eg, the first wireless audio device 220 and / or the second wireless audio device 230) being placed in a groove (eg, Figure 3 In the first groove 320 and / or the second groove 325 of the electronic device 210, at least one terminal of the wireless audio device may be in physical contact with at least one terminal 345 of the electronic device 210. Based on the physical contact between the at least one terminal of the wireless audio device and the at least one terminal 345 of the electronic device 210, a communication channel may be established between the electronic device 210 and the first wireless audio device 220 or the second wireless audio device 230. This communication channel may be implemented as a power line communication (PLC) channel.

[0216] In an embodiment, when the external electronic device 240 detects an input for enabling the FM radio reception function, the external electronic device 240 may notify the first wireless audio device 220 and / or the second wireless audio device 230 that the FM radio reception function has been enabled. When the first wireless audio device 220 and / or the second wireless audio device 230 are installed in the electronic device 210 based on the installation-related guidance information, the electronic device 210 may enable the FM radio reception circuit 610 via power line communication (PLC).

[0217] As reference number <1230> and <1250> As shown, in the first wireless audio device 220 and the second wireless audio device 230, the first wireless audio device 220 is installed in the electronic device 210, and the second wireless audio device 230 is worn in the right ear of the user, a reference according to an embodiment is provided. Figure 12 Description.

[0218] In an embodiment, based on the first wireless audio device 220 being installed in the electronic device 210, the electronic device 210 may transmit the FM radio signal received via the FM radio receiving circuit 610 via the PLC circuit (eg, Figure 6The PLC circuit 643 of the electronic device 210) is transmitted to the first wireless audio device 220. The first wireless audio device 220 may transmit the FM radio signal received from the electronic device 210 to the paired second wireless audio device 230 via short-range communication (eg, Bluetooth communication).

[0219] In an embodiment, the second wireless audio device 230 may output the FM radio signal received from the paired first wireless audio device 220 via the speaker 730 .

[0220] Without limitation thereto, and although not shown, the electronic device 210 may detect an input for enabling the FM radio reception function while the first wireless audio device 220 and the second wireless audio device 230 are installed in the electronic device 210. The electronic device 210 may enable the FM radio reception circuit 610 based on the detection of the input for enabling the FM radio reception function. Based on the activation of the FM radio reception circuit 610, the electronic device 210 may provide installation-related guidance information so that one of the first wireless audio device 220 and the second wireless audio device 230 is installed in the electronic device 210. For example, the electronic device 210 may provide guidance information related to installation via an indicator (e.g., Figure 3 The electronic device 210 may further include an indicator 340 (e.g., an indicator 340) that outputs installation-related guidance information, so that one of the first wireless audio device 220 and the second wireless audio device 230 is installed in the electronic device 210. However, this is not limited to this. When one of the first wireless audio device 220 and the second wireless audio device 230 installed in the electronic device 210 (e.g., the first wireless audio device 220 or the second wireless audio device 230) is detected as being separated from the electronic device 210, the electronic device 210 may transmit the FM radio signal received via the enabled FM radio receiving circuit 610 to the wireless audio device installed in the electronic device 210 (e.g., the first wireless audio device 220 or the second wireless audio device 230) via the PLC circuit 643. A wireless audio device installed in the electronic device 210 (e.g., the first wireless audio device 220 or the second wireless audio device 230) may transmit an FM radio signal received from the electronic device 210 to a wireless audio device not installed in the electronic device 210 (e.g., the second wireless audio device 230 or the first wireless audio device 220) via short-range communication (e.g., Bluetooth communication).

[0221] In various embodiments, regardless of whether the electronic device 210 is in a closed state or an open state, a wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) installed in the electronic device 210 can communicate with the user via a short-range communication circuit (e.g., Figure 7The short-range communication circuit 705 of the electronic device 210 transmits an FM radio signal to a wireless audio device (e.g., the second wireless audio device 230 or the first wireless audio device 220) that is not installed in the electronic device 210. For example, when the FM radio receiving circuit 610 of the electronic device 210 is in an enabled state, the short-range communication circuit (e.g., the first wireless audio device 220 and the second wireless audio device 230) of the wireless audio device (e.g., Figure 7 The short-range communication circuit 705 of the FM radio receiving circuit 610 may remain in an enabled state regardless of whether the electronic device 210 is in a closed state or an open state. In an embodiment, when the FM radio receiving circuit 610 is disabled and the electronic device 210 is in a closed state, the short-range communication circuit 705 of a wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) installed in the electronic device 210 may be switched to a disabled state.

[0222] Figure 13a is a flowchart illustrating a method of outputting an FM radio signal of the electronic device 210 according to an embodiment of the present disclosure.

[0223] In the following embodiments, the various operations may be performed sequentially, but need not be performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0224] According to an embodiment, operations 1305 to 1315 may be understood as a process performed by an electronic device (eg, Figure 6 The processor of the electronic device 210 (eg, Figure 6 Processor 645) executes.

[0225] In an embodiment, in operation 1305, the processor 645 may detect that a state in which the first wireless audio device (e.g., the first wireless audio device 220 of FIG. 2 ) and the second wireless audio device (e.g., the second wireless audio device 230 of FIG. 2 ) are separated from the electronic device 210 has been converted to a state in which one of the first wireless audio device 220 and the second wireless audio device 230 is installed in the electronic device 210.

[0226] For example, the first wireless audio device 220 and the second wireless audio device 230 may be detached from the electronic device 210 and worn in the user's ears. For example, the external electronic device 240 may receive sensor information (e.g., sensor information obtained using a proximity sensor based on an electromagnetic field or electromagnetic wave (e.g., infrared light) that is emitted and then returned, sensor information obtained using a grip sensor based on a change in capacitance or dielectric constant, and / or sensor information related to movement of the wireless audio devices) from each of the first wireless audio device 220 and the second wireless audio device 230. Based on the received sensor information, the external electronic device 240 may determine whether the first wireless audio device 220 and the second wireless audio device 230 are worn in the user's ears.

[0227] In an embodiment, while the first wireless audio device 220 and the second wireless audio device 230 are worn in the user's ears after being separated from the electronic device 210, the first wireless audio device 220 and the second wireless audio device 230 may be paired with an external electronic device (e.g., the external electronic device 240 of FIG. 2 ) to output an audio signal (e.g., an audio signal according to an incoming call, a received message, an alarm, or audio playback) received from the external electronic device 240. However, this is not limited thereto.

[0228] In an embodiment, the external electronic device 240 may identify whether an input for enabling the FM radio reception function is detected. For example, the external electronic device 240 may execute an application related to the FM radio reception function in response to a user input, and may detect the input for enabling the FM radio reception function via the running application related to the FM radio reception function. In this case, the external electronic device 240 may provide installation-related guidance information for guiding one of the first wireless audio device 220 and the second wireless audio device 230 (e.g., the first wireless audio device 220 or the second wireless audio device 230) to a state of being installed in the electronic device 210, so that the FM radio reception circuit (e.g., the second wireless audio device 230) provided in the electronic device 210 is activated. Figure 6 The FM radio signal received by the FM radio receiving circuit 610 of the external electronic device is output via the wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230). The installation-related guidance information according to the embodiment may include visual information and / or audio information. For example, the external electronic device 240 may display the information on a display (e.g., Figure 1The external electronic device 240 may output visual information for guiding one of the wireless audio devices to a placement state in the electronic device 210 on the display module 160 of the user's device. As another example, the external electronic device 240 may transmit placement-related guidance information to the wireless audio devices worn in the user's ears (e.g., the first wireless audio device 220 and the second wireless audio device 230). The wireless audio devices worn in the user's ears (e.g., the first wireless audio device 220 and the second wireless audio device 230) may receive the audio through speakers (e.g., Figure 7 The speaker 730 of the electronic device 210 outputs audio information for guiding one of the wireless audio devices to the placement state in the electronic device 210. However, this is not limited thereto.

[0229] In an embodiment, the processor 645 may identify whether at least one terminal included in the first wireless audio device 220 and / or the second wireless audio device 230 is connected to the first housing structure (eg, Figure 3 The first housing structure 305) is provided with a first groove (eg, Figure 3 ) and a second groove (eg, Figure 3 at least one terminal (eg, Figure 3 The electronic device 210 makes physical contact with at least one terminal 345 , thereby identifying whether the first wireless audio device 220 and / or the second wireless audio device 230 is installed in the electronic device 210 .

[0230] In an embodiment, when one of the first wireless audio device 220 and the second wireless audio device 230 is detected as being installed in the electronic device 210, the processor 645 may enable the FM radio reception circuit 610 in operation 1310. In an embodiment, when an input for enabling the FM radio reception function is detected, the external electronic device 240 may notify the first wireless audio device 220 and / or the second wireless audio device 230 that the FM radio reception function has been enabled. When the first wireless audio device 220 and / or the second wireless audio device 230 is installed in the electronic device 210 based on the installation-related guidance information, the electronic device 210 may enable the FM radio reception circuit 610 via power line communication (PLC).

[0231] In an embodiment, in operation 1315, the processor 645 may receive an FM radio signal via the FM radio receiving circuit 610 and transmit the signal via the PLC circuit (eg, Figure 6 The PLC circuit 643) transmits the received FM radio signal to the installed wireless audio device.

[0232] Although not shown, the wireless audio device (eg, the first wireless audio device 220 or the second wireless audio device 230) installed in the electronic device 210 may communicate with the user via a short-range communication circuit (eg, Figure 7 The short-range communication circuit 705 of the electronic device 210 transmits the FM radio signal received from the electronic device 210 to the wireless audio device worn in the user's ear (e.g., the second wireless audio device 230 or the first wireless audio device 220). The wireless audio device worn in the user's ear (e.g., the second wireless audio device 230 or the first wireless audio device 220) can output the FM radio signal received from the wireless audio device installed in the electronic device 210 (e.g., the first wireless audio device 220 or the second wireless audio device 230).

[0234] In the following embodiments, each operation may be performed sequentially, but need not be performed in this order. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0235] According to an embodiment, operations 1330 to 1350 may be understood as being executed by a processor (eg, Figure 1 Operations 1355 to 1370 may be understood as being performed by a processor (eg, Figure 6 Operation 1375 may be understood as being performed by a processor (eg, a processor of the first wireless audio device (eg, the first wireless audio device 220 of FIG. 2 ) Figure 7 2 ), and operation 1380 may be understood to be performed by the processor 745 of the second wireless audio device (eg, the second wireless audio device 230 of FIG. 2 ).

[0236] According to various embodiments Figure 13b Operations 1355 to 1370 are the same as those described above. Figure 13a Operations 1305 to 1315 are substantially the same, so their detailed descriptions are available Figure 13a Description instead.

[0237] Reference Figure 13b , the first wireless audio device 220 and the second wireless audio device 230 may be detached from the user's electronic device 210 , worn in the user's ears, and paired with the external electronic device 240 .

[0238] In an embodiment, in operation 1330, the external electronic device 240 may communicate with the user via a short-range communication circuit (eg, Figure 1 The wireless communication circuit 192 of the first wireless audio device 220 transmits an audio signal (e.g., an audio signal according to an incoming call, message reception, alarm, or audio playback) to the first wireless audio device 220. In operation 1335, the external electronic device 240 may transmit the audio signal to the second wireless audio device 230 via the short-range communication circuit 192. Although not shown, each of the first wireless audio device 220 and the second wireless audio device 230 may transmit the audio signal to the second wireless audio device 230 via a speaker (e.g., Figure 7 The speaker 730 ) outputs the audio signal received from the external electronic device 240 .

[0239] In an embodiment, the external electronic device 240 may detect an input for enabling the FM radio reception function at operation 1340. For example, the external electronic device 240 may run an application related to the FM radio reception function and detect the input for enabling the FM radio reception function via the running application related to the FM radio reception function.

[0240] In an embodiment, in operation 1345, the external electronic device 240 may transmit placement-related information to the first wireless audio device 220 via the short-range communication circuit 192, and the placement-related information may guide the first wireless audio device 220 to a placement state in the electronic device 210. In operation 1350, the external electronic device 240 may transmit placement-related information to the second wireless audio device 230 via the short-range communication circuit 192, and the placement-related information may guide the second wireless audio device 230 to a placement state in the electronic device 210.

[0241] For example, the external electronic device 240 may provide installation-related information for guiding one of the first wireless audio device 220 and the second wireless audio device 230 (e.g., the first wireless audio device 220 or the second wireless audio device 230) to be installed in the electronic device 210 so that the FM radio receiving circuit (e.g., Figure 6 The FM radio signal received by the FM radio receiving circuit 610 is output through a wireless audio device (eg, the first wireless audio device 220 or the second wireless audio device 230). The placement-related information according to an embodiment may include visual information and / or audio information.

[0242] In an embodiment, in operation 1355, the electronic device 210 may detect that one of the first wireless audio device 220 and the second wireless audio device 230 is installed in the electronic device 210. Based on the detection that one of the first wireless audio device 220 and the second wireless audio device 230 is stably installed in the electronic device 210, in operation 1360, the electronic device 210 may enable the FM radio reception circuit 610. In an embodiment, when the first wireless audio device 220 and the second wireless audio device 230 are installed in the electronic device 210 based on the installation-related guidance information, the first wireless audio device 220 and the second wireless audio device 230 may cause the electronic device 210 to enable the FM radio reception circuit 610 via power line communication (PLC).

[0243] In an embodiment, in operation 1365 , the electronic device 210 may receive an FM radio signal via the FM radio receiving circuit 610 .

[0244] On the assumption that the wireless audio device installed in the electronic device 210 is the first wireless audio device 220, references to various embodiments are provided. Figure 13b Description.

[0245] In an embodiment, in operation 1370, the electronic device 210 may transmit the FM radio signal received via the FM radio receiving circuit 610 via a PLC circuit (eg, Figure 6 The PLC circuit 643 is sent to the first wireless audio device 220.

[0246] In an embodiment, in operation 1375, the first wireless audio device 220 may transmit the FM radio signal received from the electronic device 210 via a short-range communication circuit (eg, Figure 7 The short-range communication circuit 705 of the second wireless audio device 230 is sent to the second wireless audio device 230. In operation 1380, the second wireless audio device 230 may receive the audio signal through a speaker (eg, Figure 7 The speaker 730 of the first wireless audio device 220 outputs the FM radio signal received from the first wireless audio device 220.

[0247] Figure 14a is a flowchart illustrating a method of outputting an FM radio signal of the electronic device 210 according to an embodiment of the present disclosure.

[0248] In the following embodiments, the various operations may be performed sequentially, but need not be performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0249] According to an embodiment, operations 1405 to 1420 may be understood as being performed by an electronic device (eg, Figure 6 The processor of the electronic device 210 (eg, Figure 6 Processor 645) executes.

[0250] In an embodiment, when a first wireless audio device (e.g., the first wireless audio device 220 of FIG. 2 ) and a second wireless audio device (e.g., the second wireless audio device 230 of FIG. 2 ) are installed in the electronic device 210, the processor 645 may detect an input for enabling an FM radio reception function in operation 1405. For example, the input for enabling the FM radio reception function may include a housing structure (e.g., Figure 3 The present invention also includes the following steps: operating a physical button (e.g., a key button) on the first housing structure 305 and / or the second housing structure 310 of the present invention; a touch input detected via a touch sensor provided on the housing structure 305 and / or 310; a voice input related to activation of the FM radio reception function; and a wireless signal related to activation of the FM radio reception function (e.g., a signal input via an input circuit (e.g., a signal input) provided separately in the wireless audio device). Figure 7 The input circuit 720) detects the operation-related signal).

[0251] In an embodiment, based on the detection of the input for enabling the FM radio reception function, in operation 1410, the processor 645 may enable the FM radio reception circuit (eg, Figure 6 FM radio receiving circuit 610).

[0252] In an embodiment, after the FM radio receiving circuit 610 is enabled, the processor 645 may detect that one of the first wireless audio device 220 and the second wireless audio device 230 is separated from the electronic device 210 in operation 1415. For example, the processor 645 may identify whether at least one terminal included in the first wireless audio device 220 and / or the second wireless audio device 230 is connected to a first housing structure (e.g., Figure 3 The first housing structure 305) has a first groove (eg, Figure 3 ) and a second groove (eg, Figure 3 The first wireless audio device 220 and the second wireless audio device 230 are physically contacted with at least one terminal configured in the second groove 325 of the electronic device 210 , thereby identifying whether one of the first wireless audio device 220 and the second wireless audio device 230 is separated from the electronic device 210 .

[0253] In an embodiment, when it is detected that one of the first wireless audio device 220 and the second wireless audio device is separated from the electronic device 210, in operation 1420, the processor 645 may receive an FM radio signal via the FM radio receiving circuit 610 and receive the FM radio signal via the PLC circuit (e.g., Figure 6The processor 645 may transmit the received FM radio signal to the installed wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) via the PLC circuit 643. For example, in order to output the FM radio signal (the FM radio signal is received from the enabled FM radio reception circuit 610) via the wireless audio device (e.g., the second wireless audio device 230 or the first wireless audio device 220) separated from the electronic device 210, the processor 645 may transmit the FM radio signal via the wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) installed in the electronic device 210 to another wireless audio device (e.g., the second wireless audio device 230 or the first wireless audio device 220) paired with the wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230), thereby outputting the FM radio signal via the other wireless audio device (e.g., the second wireless audio device 230 or the first wireless audio device 220).

[0254] In an embodiment, although not shown, after the FM radio reception circuit 610 is activated, the processor 645 may perform an operation of identifying whether one of the first wireless audio device 220 and the second wireless audio device 230 is separated from the electronic device 210 within a specified time. When neither the first wireless audio device 220 nor the second wireless audio device 230 is identified as being separated from the electronic device 210 within the specified time, the processor 645 may perform control so that the activated FM radio reception circuit 610 is in a deactivated state.

[0255] In an embodiment, while one of the first wireless audio device 220 or the second wireless audio device 230 is installed in the electronic device 210, the electronic device 210 may also detect an input for enabling an FM radio reception function. The electronic device 210 may enable the FM radio reception circuit 610, receive an FM radio signal via the FM radio reception circuit 610, and receive an FM radio signal via the PLC circuit (e.g., Figure 6 The PLC circuit 643 of the wireless audio device 100 transmits the received FM radio signal to the installed wireless audio device (eg, the first wireless audio device 220 or the second wireless audio device 230 ).

[0256] Figure 14b A signal flow between the electronic device 210 , the first wireless audio device 220 , and the second wireless audio device 230 according to an embodiment of the present disclosure is shown.

[0257] In the following embodiments, the various operations may be performed sequentially, but need not be performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0258] According to an embodiment, operations 1455 to 1470 may be understood as being executed by a processor (eg, Figure 6 Operation 1475 may be understood as being performed by a processor (eg, a processor of the first wireless audio device (eg, the first wireless audio device 220 of FIG. 2 )) of the first wireless audio device (eg, Figure 7 Operation 1480 may be understood as being performed by the processor 745 of the second wireless audio device (eg, the second wireless audio device 230 of FIG. 2 ).

[0259] According to various embodiments Figure 14b Operations 1455 to 1470 are the same as above Figure 14a Operations 1405 to 1420 are substantially the same, and therefore, their detailed descriptions are available. Figure 14a Description instead.

[0260] Reference Figure 14b In operation 1455, while the first wireless audio device 220 and / or the second wireless audio device 230 is installed in the electronic device 210, the electronic device 210 may detect an input for enabling the FM radio reception function. Based on the detection of the input for enabling the FM radio reception function, in operation 1460, the electronic device 210 may enable the FM radio reception circuit (e.g., Figure 6 FM radio receiving circuit 610).

[0261] The reference according to the embodiment is provided on the assumption that the second wireless audio device 230 of the first wireless audio device 220 and the second wireless audio device 230 is separated from the electronic device 210. Figure 14b Description.

[0262] In an embodiment, in operation 1465 , when the second wireless audio device 230 of the first wireless audio device 220 and the second wireless audio device 230 is detected as being separated from the electronic device 210 , the electronic device 210 may receive an FM radio signal via the FM radio reception circuit 610 .

[0263] In an embodiment, in operation 1470, the electronic device 210 may, via a PLC circuit (eg, Figure 6 The PLC circuit 643 of the electronic device 210 transmits an FM radio signal to the first wireless audio device 220 (eg, the first wireless audio device 220 disposed in the electronic device 210 ).

[0264] In an embodiment, in operation 1475, the first wireless audio device 220 may communicate with the user via a short-range communication circuit (eg, Figure 7The short-range communication circuit 705 of the electronic device 210 transmits the FM radio signal received from the second wireless audio device 230. In operation 1480, the second wireless audio device 230 may output the FM radio signal received from the first wireless audio device 220.

[0265] Although not shown in various embodiments, one wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) may be installed in the electronic device 210 while simultaneously outputting an audio signal received from the external electronic device 240 via another wireless audio device (e.g., the second wireless audio device 230 or the first wireless audio device 220). Furthermore, the electronic device 210 may be in a closed state, and therefore, the short-range communication circuit 705 of the wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) installed in the electronic device 210 may be in a deactivated state. In this case, when an input for activating the FM radio reception function is detected, the electronic device 210 may activate the FM radio reception circuit 610 and control the short-range communication circuit 705 of the wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) installed in the electronic device 210 to be activated. For example, the electronic device 210 may activate the short-range communication circuit 705 of a wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) located in the electronic device 210 by transmitting a signal related to activation of the short-range communication circuit 705 via the PLC circuit 643. In an embodiment, the electronic device 210 may transmit an FM radio signal received via the FM radio reception circuit 610 to the wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) located in the electronic device 210 via the PLC circuit 643. The wireless audio device (e.g., the first wireless audio device 220 or the second wireless audio device 230) located in the electronic device 210 may transmit the FM radio signal to the wireless audio device (e.g., the second wireless audio device 230 or the first wireless audio device 220) located in the electronic device 210 via the short-range communication circuit 705, thereby causing the wireless audio device (e.g., the second wireless audio device 230 or the first wireless audio device 220) located in the electronic device 210 to output an FM radio signal.

[0266] Figure 15 An input circuit 630 of the electronic device 210 according to an embodiment of the present disclosure is shown.

[0267] Reference Figure 15 , the input circuit of the electronic device 210 (eg, Figure 6The input circuit 630) may include a circuit configured to perform communication with a receiver via an FM radio (e.g., Figure 6 At least one electrode of the FM radio receiving circuit 610 (e.g., the FM radio receiving circuit 610) is configured to receive FM radio signals. For example, the functions associated with FM radio signals may include: a function for configuring the strength of FM radio signals output by a wireless audio device (e.g., the first wireless audio device 220 and / or the second wireless audio device 230 in FIG. 2 ) (e.g., volume increase / decrease), a function for configuring FM radio broadcast channels (e.g., channel search, channel change), and / or a function for activating or deactivating the FM radio reception function. However, this is not limited to this.

[0268] In an embodiment, at least one electrode may be provided in at least a portion of one surface of the second housing structure 310 of the electronic device 210. The at least one electrode may be provided as at least one button for detecting input for executing a function related to FM radio signals. For example, the at least one button may be implemented as a physical button (e.g., a key button with a mechanical switch), a touch sensor (e.g., a capacitive or piezoelectric type), or a pressure sensor. However, this is not limited to this.

[0269] In embodiments, the at least one electrode may include a first electrode 1520 , a second electrode 1530 , a third electrode 1540 and / or a fourth electrode 1550 .

[0270] In an embodiment, the printed circuit board 455 may be disposed in the inner space of the first housing structure 305 of the electronic device 210. The touch circuit 1510 may be disposed on (or included in) the printed circuit board 455.

[0271] In embodiments, at least one electrode (eg, first electrode 1520 , second electrode 1530 , third electrode 1540 and / or fourth electrode 1550 ) may be electrically connected to a touch circuit 1510 disposed on a printed circuit board 455 via a flexible printed circuit board (FPCB) 1560 .

[0272] In an embodiment, at least one electrode (eg, the first electrode 1520, the second electrode 1530, the third electrode 1540, and / or the fourth electrode 1550) may be mapped to a function associated with an FM radio signal. Figure 16 Various embodiments are described in detail.

[0273] In embodiments, when at least one electrode (e.g., the first electrode 1520, the second electrode 1530, the third electrode 1540, and / or the fourth electrode 1550) is electrically connected to the touch circuit 1510 provided on the printed circuit board 455 via the flexible printed circuit board (FPCB) 1560, the electronic device 210 may detect a capacitance change exceeding a specified value at the at least one electrode (e.g., the first electrode 1520, the second electrode 1530, the third electrode 1540, and / or the fourth electrode 1550) via the touch circuit 1510. For example, the electronic device 210 may detect a capacitance change exceeding a specified value via the touch circuit 1510 based on contact of a conductive member (e.g., a finger) with the at least one electrode (e.g., the first electrode 1520, the second electrode 1530, the third electrode 1540, and / or the fourth electrode 1550). The electronic device 210 may perform a function related to an FM radio signal mapped to at least one electrode (eg, the first electrode 1520 , the second electrode 1530 , the third electrode 1540 , and / or the fourth electrode 1550 ) in which a capacitance change exceeding a specified value has been detected.

[0274] According to various embodiments Figure 15 It is shown that four electrodes are provided in the second housing structure 310 , but this is merely one embodiment and is not limited thereto.

[0275] Figure 16 The operation of the input circuit 630 of the electronic device 210 according to an embodiment of the present disclosure is illustrated.

[0276] Reference Figure 16 , as referenced Figure 15 As described, the second housing structure 310 of the electronic device 210 may be provided with a first electrode 1520, a second electrode 1530, a third electrode 1540, and / or a fourth electrode 1550 for performing functions related to FM radio signals. Each of the first electrode 1520, the second electrode 1530, the third electrode 1540, and the fourth electrode 1550 may be implemented as a capacitive touch sensor. However, this is not limited thereto.

[0277] In embodiments, at least one electrode (e.g., the first electrode 1520, the second electrode 1530, the third electrode 1540, and / or the fourth electrode 1550) may be mapped to a function related to FM radio signals, as described above. For example, as shown by reference numeral 1610, the first electrode 1520 and the second electrode 1530 may be mapped to functions for configuring the intensity of FM radio signals output by wireless audio devices (e.g., the first wireless audio device 220 and / or the second wireless audio device 230), such as volume down function 1615 and volume up function 1620. The third electrode 1540 and the fourth electrode 1550 may be mapped to functions for configuring FM radio broadcast channels (e.g., the second channel 1625 and the first channel 1630 of the FM radio broadcast). However, this is not limited to this.

[0278] In an embodiment, the processor of the electronic device 210 (eg, Figure 6 The processor 645) can be connected to the touch circuit (eg, Figure 15 The touch circuit 1510 of the electronic device 210 detects a change in capacitance at each electrode (e.g., the first electrode 1520, the second electrode 1530, the third electrode 1540, and / or the fourth electrode 1550). For example, based on contact between the conductive member 1655 (e.g., a finger) and at least one electrode (e.g., the first electrode 1520, the second electrode 1530, the third electrode 1540, and / or the fourth electrode 1550), the electronic device 210 can detect the change in capacitance via the touch circuit 1510. The electronic device 210 can perform a function related to FM radio signals mapped to the at least one electrode (e.g., the first electrode 1520, the second electrode 1530, the third electrode 1540, and / or the fourth electrode 1550) for which the change in capacitance has been detected.

[0279] The present disclosure is not limited thereto. As shown by reference numeral 1650, upon detecting a gesture by a conductive member 1655 (e.g., a finger) on a touch area 1660 disposed on one surface of the second housing structure 310 of the electronic device 210, the electronic device 210 may execute a function related to FM radio signals corresponding to the detected gesture. In embodiments, the functions related to FM radio signals mapped to different gestures may be different. For example, the description is provided assuming that the function mapped to the first gesture 1665 (e.g., a swipe gesture) is for searching for FM radio channels, and the function mapped to the second gesture (e.g., a press-and-drag gesture) is for controlling volume. For example, when a gesture 1665 (e.g., a swipe gesture) by a conductive member 1655 (e.g., a finger) is detected on the touch area 1660 disposed on one surface of the second housing structure 310 of the electronic device 210, the electronic device 210 may execute the function for searching for FM radio channels. For another example, when a second gesture (eg, a long press and drag gesture) is detected in the touch area 1660 configured on one surface of the second housing structure 310 of the electronic device 210 , the electronic device 210 may execute a volume control function.

[0280] The present disclosure is not limited thereto, and may also be based on a microphone (eg, Figure 7 The microphone 735) receives the voice command to execute the function related to the FM radio signal corresponding to the voice command.

[0283] In an embodiment, an electronic device (eg, electronic device 210 of FIG. 2 ) may include FM radio receiving circuitry (eg, Figure 6 The FM radio receiving circuit 610) is configured to receive an FM radio broadcast (eg, a frequency modulation (FM) radio broadcast using a signal in a frequency band of 87.5 MHz to 108.0 MHz).

[0284] According to the above Figures 3 to 16In an embodiment, the electronic device 210 may enable the FM radio reception circuit 610 based on detection of an input for enabling the FM radio reception function, and receive FM radio signals via the enabled FM radio reception circuit 610.
