Description

Electronic device for providing at least one sound channel to another electronic device and method for controlling the same

[0001] The present disclosure relates to an electronic device and a method for controlling the same, and more particularly, to an electronic device that provides at least one sound channel to another electronic device and a method for controlling the same.

[0002] Advances in electronic technology have led to the development of a diverse range of electronic devices. In particular, the recent proliferation of various types of speakers has enhanced user convenience.

[0003] For example, a soundbar is installed like a TV in a shared space like the living room, providing a screen for the family. Its audio positioning and multi-channel output can provide a sense of immersion for the user. Wireless earphones, worn on the user's ears, allow them to enjoy sound without disturbing others, enhancing user convenience.

[0004] However, speakers such as soundbars have limitations in channel expansion in terms of installation, and accordingly, there is a need to supplement the limitations in channel expansion through various sound devices.

[0005] The aspects will be partly explained in the following description, and some will become apparent from the description or can be learned by practicing the examples presented.

[0006] According to one embodiment of the present disclosure for achieving the above object, an electronic device includes a communication interface, at least one memory storing instructions, and at least one processor connected to the communication interface to control the electronic device, and by executing the instructions, the at least one processor can control the communication interface to identify whether a preset function is activated in the second electronic device when a second electronic device is identified as being connected to the electronic device through the communication interface, and to transmit at least one channel among a plurality of channels included in the sound information to the second electronic device based on whether the preset function is identified as being activated.

[0007] Additionally, the one or more processors may control the communication interface to transmit a preset channel among the plurality of channels to the second electronic device in a state in which the preset function is identified as activated in the second electronic device, and may control the communication interface to transmit the plurality of channels to the second electronic device in a state in which the preset function is identified as not activated in the second electronic device.

[0008] And, the above preset channel may include a woofer channel.

[0009] Additionally, the one or more processors may output channels excluding the at least one channel among the plurality of channels through the speaker while transmitting the at least one channel to the second electronic device.

[0010] And, when the one or more processors are identified as being connected to the second electronic device through the communication interface, the one or more processors control the communication interface to transmit a signal to the second electronic device to identify whether the preset function is activated, and can identify whether the preset function is activated based on a signal received from the second electronic device through the communication interface.

[0011] In addition, one of the at least one memory stores specification information of the second electronic device, and the one or more processors can control the communication interface to identify whether the second electronic device can perform the preset function based on the specification information, and transmit a signal to the second electronic device to identify whether the preset function is activated when the second electronic device is identified as being capable of performing the preset function.

[0012] And, further comprising a speaker, wherein the one or more processors control the communication interface to transmit to the second electronic device at least one channel having a frequency lower than a preset frequency at which negative positioning is impossible, and output through the speaker at least one channel having a frequency higher than the preset frequency at which negative positioning is possible.

[0013] Additionally, the one or more processors may control the communication interface to compensate for latency of the at least one channel and transmit the compensated at least one channel to the second electronic device.

[0014] And, the one or more processors can identify the location of the second electronic device and compensate for the latency based on the location of the second electronic device.

[0015] Alternatively, the speaker may further include a speaker, and the one or more processors may output an inaudible sound below a preset frequency through the speaker, and compensate for the latency based on delay information received from the second electronic device through the communication interface.

[0016] The delay information may include a reception time at which the inaudible sound is received by the second electronic device, wherein the one or more processors may be configured to compensate for the delay time based on a time at which the inaudible sound is output and a reception time at which the inaudible sound is received by the second electronic device.

[0017] Additionally, the preset function may be a function of generating a mixture including a sound received through a microphone of the second electronic device and a sound based on the at least one channel received from the electronic device, and outputting the mixture through a speaker of the second electronic device.

[0018] And, the one or more processors can identify whether the preset function is activated in the second electronic device while the sound information is output as sound and the second electronic device is connected to the electronic device through the communication interface.

[0019] Meanwhile, according to one embodiment of the present disclosure, a method for controlling an electronic device may include, when a second electronic device is identified as being connected to the electronic device, a step of identifying whether a preset function is activated in the second electronic device, and a step of transmitting at least one channel among a plurality of channels included in sound information to the second electronic device based on whether the preset function is identified as being activated.

[0020] In addition, the step of transmitting at least one channel among the plurality of channels to the second electronic device may transmit the preset channel among the plurality of channels to the second electronic device in a state in which the preset function is identified as activated in the second electronic device, and may transmit the plurality of channels to the second electronic device in a state in which the preset function is identified as not activated in the second electronic device.

[0021] And, the above preset channel may include a woofer channel.

[0041] In this specification, the term user may refer to a person using an electronic device or a device using an electronic device (e.g., an artificial intelligence electronic device).

[0042] Various embodiments of the present disclosure will be described in more detail with reference to the attached drawings below.

[0043] FIG. 1 is a block diagram illustrating the configuration of an electronic system (1000) according to an embodiment of the present disclosure. As illustrated in FIG. 1, the electronic system (1000) includes an electronic device (100) and a second electronic device (200).

[0044] The electronic device (100) is a device that outputs sound, and can be implemented as a sound bar, TV, projector (including a single-focus projector equipped with sound, a projection projector), desktop PC, laptop, smartphone, tablet PC, smart glasses, smart watch, etc. However, the electronic device (100) is not limited thereto, and any device that has a speaker and can output sound may be used.

[0045] The electronic device (100) can transmit at least one channel among a plurality of channels included in the sound to the second electronic device (200). For example, the electronic device (100) can transmit at least one channel among a plurality of channels included in the sound to the second electronic device (200) based on whether a preset function is activated in another electronic device.

[0046] The second electronic device (200) is a device worn by the user to output sound, and can be implemented as earphones, a headset, VR glasses, AR glasses, XR glasses, etc. That is, the user wearing the second electronic device (200) can hear the sound output from the second electronic device (200), but people around the user cannot hear the sound output from the second electronic device (200) or can only hear it at a very low volume, thereby preventing damage caused by noise in the surroundings. For the convenience of explanation, it is described below that the sound output from the second electronic device (200) is heard only by the user wearing the second electronic device (200).

[0047] The second electronic device (200) may be a device that supports a preset function. For example, the preset function may be a function that mixes a sound received through a microphone of the second electronic device (200) with at least one channel received from the electronic device (100) and outputs the mixed sound through a speaker of the second electronic device (200), and may also be referred to as a transparency function.

[0048] However, it is not limited thereto, and the second electronic device (200) may be any device that can mix sound received through a microphone with at least one channel received from the electronic device (100) and output the sound through the speaker of the second electronic device (200).

[0049] FIG. 2 is a block diagram showing the configuration of an electronic device (100) according to one embodiment of the present disclosure.

[0050] According to FIG. 2, the electronic device (100) includes a speaker (110), a communication interface (120), and a processor (130). However, the present invention is not limited thereto, and the electronic device (100) may also be implemented in a form including a communication interface (120) and a processor (130).

[0051] The speaker (110) is a component that outputs various audio data processed by the processor (130) as well as various notification sounds and voice messages. For example, the processor (130) can output signals of some channels included in the sound through the speaker (110).

[0052] The speaker (110) may be implemented as multiple speakers. For example, the speaker (110) may include a front left speaker, a front right speaker, and a center speaker. However, this is not limited to this, and the implementation method of the speaker (110) may vary.

[0053] The communication interface (120) is a component that performs communication with various types of external devices according to various types of communication methods. For example, the electronic device (100) can perform communication with a second electronic device (200) through the communication interface (120). For example, the electronic device (100) can perform communication with the second electronic device (200) through the UWB (ultra-wideband) communication standard, and in this case, the location of the second electronic device (200) can also be identified through UWB communication.

[0054] The communication interface (120) may include a Wi-Fi module, a Bluetooth module, an infrared communication module, a wireless communication module, etc. Here, each communication module may be implemented in the form of at least one hardware chip.

[0055] Wi-Fi and Bluetooth modules communicate via Wi-Fi and Bluetooth, respectively. When using a Wi-Fi or Bluetooth module, connection information, such as the SSID and session key, is first transmitted and received. This information is then used to establish a communication connection before various other information can be transmitted and received. Infrared communication modules use infrared data association (IrDA) technology, which wirelessly transmits data over short distances using infrared light, which lies between visible light and millimeter waves.

[0056] In addition to the above-described communication method, the wireless communication module may include at least one communication chip that performs communication according to various wireless communication standards such as zigbee, 3G (3rd Generation), 3GPP (3rd Generation Partnership Project), LTE (Long Term Evolution), LTE-A (LTE Advanced), 4G (4th Generation), 5G (5th Generation), etc.

[0057] In one embodiment, the communication interface (120) may include a wired communication interface such as HDMI, DP, Thunderbolt, USB, RGB, D-SUB, DVI, etc.

[0058] The communication interface (120) may include at least one of a LAN (Local Area Network) module, an Ethernet module, or a wired communication module that performs communication using a pair cable, a coaxial cable, or an optical fiber cable.

[0059] The processor (130) controls the overall operation of the electronic device (100). In one embodiment, the processor (130) may be connected to each component of the electronic device (100) and may control the overall operation of the electronic device (100). For example, the processor (130) may be connected to components such as a speaker (110), a communication interface (120), and a memory to control the operation of the electronic device (100).

[0060] The processor (130) may be implemented as at least one processor, and may include one or more of a CPU, a GPU (Graphics Processing Unit), an APU (Accelerated Processing Unit), a MIC (Many Integrated Core), an NPU (Neural Processing Unit), a hardware accelerator, or a machine learning accelerator. The one or more processors (130) may control one or any combination of other components of the electronic device (100), and may perform operations related to communication or data processing. The one or more processors (130) may execute one or more programs or instructions stored in a memory. For example, the one or more processors (130) may perform a method according to an embodiment of the present disclosure by executing one or more instructions stored in a memory.

[0061] When a method according to an embodiment of the present disclosure includes multiple operations, the multiple operations may be performed by one processor or by multiple processors. For example, when a first operation, a second operation, and a third operation are performed by a method according to an embodiment, the first operation, the second operation, and the third operation may all be performed by the first processor, or the first operation and the second operation may be performed by the first processor (e.g., a general-purpose processor) and the third operation may be performed by the second processor (e.g., an artificial intelligence-specific processor).

[0062] One or more processors (130) may be implemented as a single core processor including one core, or may be implemented as one or more multicore processors including multiple cores (e.g., homogeneous multicores or heterogeneous multicores). When one or more processors (130) are implemented as a multicore processor, each of the multiple cores included in the multicore processor may include an internal processor memory, such as a cache memory or an on-chip memory, and a common cache shared by the multiple cores may be included in the multicore processor. In addition, each of the multiple cores (or some of the multiple cores) included in the multicore processor may independently read and execute a program instruction for implementing a method according to an embodiment of the present disclosure, or all (or some) of the multiple cores may be linked to read and execute a program instruction for implementing a method according to an embodiment of the present disclosure.

[0063] When a method according to an embodiment of the present disclosure includes a plurality of operations, the plurality of operations may be performed by one core among the plurality of cores included in a multi-core processor, or may be performed by the plurality of cores. For example, when a first operation, a second operation, and a third operation are performed by a method according to an embodiment, the first operation, the second operation, and the third operation may all be performed by a first core included in the multi-core processor, or the first operation and the second operation may be performed by a first core included in the multi-core processor, and the third operation may be performed by a second core included in the multi-core processor.

[0064] In embodiments of the present disclosure, one or more processors (130) may refer to a system on a chip (SoC) in which one or more processors and other electronic components are integrated, a single-core processor, a multi-core processor, or a core included in a single-core processor or a multi-core processor, wherein the core may be implemented as a CPU, a GPU, an APU, a MIC, an NPU, a hardware accelerator, or a machine learning accelerator, but embodiments of the present disclosure are not limited thereto. Hereinafter, for convenience of explanation, the operation of the electronic device (100) will be described using the expression processor (130).

[0065] When the processor (130) identifies that the second electronic device (200) is connected to the electronic device (100) through the communication interface (110), it can identify whether a preset function is activated in the second electronic device (200). In one embodiment, the preset function may be a transparency function.

[0066] The processor (130) can control the communication interface (110) to transmit at least one channel among a plurality of channels included in the sound to the second electronic device (200) based on whether it is activated.

[0067] For example, the processor (130) may control the communication interface (110) to transmit a preset channel among a plurality of channels to the second electronic device (200) when a preset function is activated in the second electronic device (200), and may control the communication interface (110) to transmit a plurality of channels to the second electronic device (200) when the preset function is not activated in the second electronic device (200). Here, the preset channel may include a woofer channel. That is, the processor (130) may reduce the inter-floor noise caused by the electronic device (100) by transmitting the woofer channel that may cause inter-floor noise to the second electronic device (200). However, the present invention is not limited thereto, and the processor (130) may also control the communication interface (110) to transmit not only the woofer channel but also other channels that may cause inter-floor noise to the second electronic device (200). In one embodiment, the processor (130) may control the communication interface (110) to transmit channels that the electronic device (100) cannot reproduce to the second electronic device (200). For example, the processor (130) may control the communication interface (110) to transmit surround channels, surround back channels, ATMOS height channels, etc. that are difficult to reproduce on a TV, etc., to the second electronic device (200).

[0068] The processor (130) can identify sounds based on the user's sound usage history. For example, when a preset function is activated in the second electronic device (200), the processor (130) can control the communication interface (110) to transmit at least one channel among multiple channels included in the most recently used sound to the second electronic device (200).

[0069] However, the present invention is not limited thereto, and the processor (130) may also provide a request to the user to select a sound. In one embodiment, when the processor (130) identifies that the second electronic device (200) is connected to the electronic device (100) through the communication interface (110) while outputting sound through the speaker (110), the processor (130) may also identify whether a preset function in the second electronic device (200) is activated. In this case, when the preset function in the second electronic device (200) is activated, the processor (130) may control the communication interface (110) to transmit at least one channel among a plurality of channels included in the sound being output through the speaker (110) to the second electronic device (200).

[0070] When the processor (130) transmits at least one channel to the second electronic device (200), the processor (130) may output the remaining channels, excluding at least one channel among the plurality of channels, through the speaker (110). For example, the processor (130) may transmit a woofer channel to the second electronic device (200) and output the remaining channels through the speaker (110). In this case, since the second electronic device (200) has a preset function activated, the sound of the remaining channels received through the microphone of the second electronic device (200) may be mixed with the woofer channel received from the electronic device (100) and output through the speaker of the second electronic device (200), so that the user may listen to the sound of all channels in three dimensions. In addition, the woofer channel may be output only from the second electronic device (200) to prevent inter-floor noise.

[0071] In one embodiment, the processor (130) may transmit channels that the electronic device (100) cannot reproduce to the second electronic device (200) and output the remaining channels through the speaker (110). For example, the processor (130) may transmit surround channels that the electronic device (100) cannot reproduce to the second electronic device (200) and output the remaining channels through the speaker (110). In this case, since the second electronic device (200) has a preset function activated, the sound of the remaining channels received through the microphone of the second electronic device (200) may be mixed with the surround channels received from the electronic device (100) and output through the speaker of the second electronic device (200), and the user may experience a more enhanced three-dimensional effect. In one embodiment, the processor (130) may transmit the surround channel and the woofer channel to the second electronic device (200) and output the remaining channels through the speaker (110). This action can enhance the surround channels while reducing inter-floor noise.

[0072] When the processor (130) identifies that a second electronic device (200) is connected through the communication interface (110), the processor (130) controls the communication interface (110) to transmit a signal to the second electronic device (200) to inquire whether a preset function is activated, and can identify whether the function is activated based on a signal received from the second electronic device (200) through the communication interface (110).

[0073] Alternatively, the electronic device (100) may further include a memory in which specification information of the second electronic device (200) is stored, and the processor (130) may identify whether the second electronic device (200) supports a preset function based on the specification information, and if the second electronic device (200) supports the preset function, control the communication interface (110) to transmit a signal to the second electronic device (200) to inquire whether the preset function is activated.

[0074] However, the present invention is not limited thereto, and the electronic device (100) further includes a memory in which specification information of the second electronic device (200) is stored, and the processor (130) may identify whether the second electronic device (200) supports a preset function based on the specification information, and if the second electronic device (200) supports the preset function, may control the communication interface (110) to transmit an activation command signal of a preset channel and a preset function among a plurality of channels to the second electronic device (200). In this case, the second electronic device (200) may activate the preset function, and the processor (130) may not transmit a signal to the second electronic device (200) to inquire whether the preset function is activated.

[0075] In one embodiment, the electronic device (100) further includes a memory in which specification information of the second electronic device (200) is stored, and the processor (130) may identify whether the second electronic device (200) supports a preset function based on the specification information, and if the second electronic device (200) supports the preset function, control the communication interface (110) to transmit a signal requesting activation of the preset function to the second electronic device (200). When a user of the second electronic device (200) activates the preset function and a signal indicating that the preset function has been activated is received from the second electronic device (200), the processor (130) may control the communication interface (110) to transmit a preset channel among a plurality of channels to the second electronic device (200). In one embodiment, the processor (130) may not perform any action if a signal requesting activation of a preset function is not received from the second electronic device (200) for a preset period of time after transmitting a signal requesting activation of the preset function. That is, when the user turns on the second electronic device (200) and the second electronic device (200) is connected to the electronic device (100), the processor (130) may transmit a signal requesting activation of the preset function in order to determine whether the user intends to use the second electronic device (200) in conjunction with the electronic device (100) or to use it separately.

[0076] The processor (130) controls the communication interface (110) to transmit a signal below a preset frequency that makes negative positioning impossible in at least one channel to the second electronic device (200), and can output a signal above a preset frequency that makes negative positioning possible in at least one channel through the speaker (110).

[0077] The processor (130) can control the communication interface (110) to compensate for at least one of the level or latency of at least one channel and transmit the compensated at least one channel to the second electronic device (200).

[0078] For example, the electronic device (100) further includes a memory in which latency compensation information is stored, and the processor (130) can compensate for latency based on the latency compensation information. Here, the latency compensation information may be information acquired during the initial setting process of the OOBE (Out-of-The-Box Experience) phase. For example, the latency compensation information may include information that can acquire delay information by changing the location of the second electronic device (200) in the OOBE phase and reduce the delay based on an average location among a plurality of locations. Here, the delay information may include at least one of a delay correction (propagation delay or BT delay (fixed value depending on the device).

[0079] In one embodiment, the processor (130) may identify a location of the second electronic device (200) and compensate for latency based on the location of the second electronic device (200). For example, the electronic device (100) may further include a sensor, and the processor (130) may identify a location of a user of the second electronic device (200) through the sensor, identify a location of the second electronic device (200) based on the location of the user, and compensate for latency based on the location of the second electronic device (200). In one embodiment, when the electronic device (100) is connected to the second electronic device (200) through an ultra-wideband (UWB) communication standard, the processor (130) may identify a location of the second electronic device (200) through UWB communication, and compensate for latency based on the location of the second electronic device (200). In one embodiment, a user wearing a second electronic device (200) identifies a distance to the electronic device (100) through a smartphone or the like, provides the identified distance to the electronic device (100), and the processor (130) may compensate for latency based on the identified distance.

[0080] In one embodiment, the processor (130) may output an inaudible sound through the speaker (110), and when delay information is received from the second electronic device (200) through the communication interface (120), latency may be compensated based on the delay information. For example, when the processor (130) identifies that the second electronic device (200) is connected to the electronic device (100), the processor (130) may output an inaudible sound through the speaker (110). The second electronic device (200) may obtain information about a reception time at which the inaudible sound is received, and provide the information about the reception time to the electronic device (100). The processor (130) may obtain a propagation delay as delay information based on the time at which the inaudible sound is output and the reception time from the second electronic device (200), and may compensate for latency based on the delay information. In one embodiment, the delay information may further include a BT delay from when the second electronic device (200) receives and outputs at least one channel. Here, the BT delay may be the data transmission time between the first body and the second body when the second electronic device (200) includes a first body and a second body physically separated from the first body. In this case, the second electronic device (200) may obtain the BT delay based on the reception time at which at least one channel is received and the time at which at least one channel is output through a speaker, and provide the BT delay to the electronic device (100) together with information about the reception time at which an inaudible sound is received.

[0081] Through the above actions, the user can receive sound of consistent quality regardless of the position movement.

[0082] The processor (130) may output a low-frequency signal through the speaker (110) based on the specifications of the second electronic device (200). For example, the processor (130) may transmit a woofer channel to the second electronic device (200) and output the woofer channel through the speaker (110) based on the specifications of the second electronic device (200). In this case, the output of the woofer channel of the electronic device (100) may be lower than the output of the original signal, thereby providing the user with a sound with reinforced low-frequency while reducing inter-floor noise.

The one or more processors (240) may execute one or more programs or instructions stored in a memory. For example, the one or more processors (240) may perform a method according to an embodiment of the present disclosure by executing one or more instructions stored in a memory.

[0118] When a method according to an embodiment of the present disclosure includes multiple operations, the multiple operations may be performed by one processor or by multiple processors. For example, when a first operation, a second operation, and a third operation are performed by a method according to an embodiment, the first operation, the second operation, and the third operation may all be performed by the first processor, or the first operation and the second operation may be performed by the first processor (e.g., a general-purpose processor) and the third operation may be performed by the second processor (e.g., an artificial intelligence-specific processor).

[0119] One or more processors (240) may be implemented as a single core processor including one core, or may be implemented as one or more multicore processors including multiple cores (e.g., homogeneous multicores or heterogeneous multicores). When one or more processors (240) are implemented as a multicore processor, each of the multiple cores included in the multicore processor may include an internal processor memory, such as a cache memory or an on-chip memory, and a common cache shared by the multiple cores may be included in the multicore processor.

However, for convenience of explanation, the operation of the second electronic device (200) is described below using the expression processor (240).

[0122] In one embodiment, when the second electronic device (200) is implemented in a form that includes a first body and a second body physically separated from the first body, the communication interface (210) may include a first sub-communication interface included in the first body and a second sub-communication interface included in the second body, the microphone (220) may include a first microphone included in the first body and a second microphone included in the second body, and the speaker (230) may include a first speaker included in the first body and a second speaker included in the second body. The processor (240) may be provided in one of the first body and the second body, and may control the entire second electronic device (200) by providing a control signal to a body that is not provided with the processor (240).

[0123] The processor (240) can be connected to the electronic device (100) when the second electronic device (200) is turned on. For example, when the second electronic device (200) is turned on, the processor (240) can be connected to the electronic device (100) via Bluetooth based on past connection history with the electronic device (100).

[0124] When a signal inquiring about whether a preset function is activated from an electronic device (100) is received through a communication interface (210), the processor (240) can control the communication interface (210) to transmit a signal indicating whether the preset function is activated to the electronic device (100).

[0125] The processor (240) can mix the sound received through the microphone (220) with at least one channel and output it through the speaker (230) when at least one channel is received from the electronic device (100) with a preset function activated. Here, at least one channel can include a woofer channel.

[0126] The processor (240) can strengthen a signal below a preset frequency from sound received through at least one channel and a microphone (220), mix the strengthened sound received through at least one channel and a microphone (220), and output the mixed signal through a speaker (230).

[0127] The second electronic device (200) further includes a memory in which hearing loss profile information of a user of the second electronic device (200) is stored, and the processor (240) may process sound received through at least one channel and the microphone (220) based on the hearing loss profile information, mix the processed at least one channel and the processed sound, and output the mixed sound through the speaker (230). In one embodiment, the processor (240) may process only sound received through the microphone (220) based on the hearing loss profile information, and mix the processed sound through the speaker (230).

[0128] The processor (240) can compensate for a frequency band corresponding to hearing loss profile information in sound received through at least one channel and a microphone (220), mix the compensated at least one channel and the compensated sound, and output the same sound through a speaker (230). Through this operation, the processor (240) can provide the same sound experience to a hearing-impaired user and other users.

[0129] The second electronic device (200) further includes a sensor, and the processor (240) can identify the rotation of the second electronic device (200) through the sensor, process at least one channel based on the rotation of the second electronic device (200), and mix the processed at least one channel and sound received through the microphone (220) to output the sound through the speaker (230).

[0130] In one embodiment, the processor (240) may identify the rotation of the second electronic device (200) and the orientation of the head of a user wearing the second electronic device (200) through a sensor, process at least one channel based on the rotation of the second electronic device (200) and the orientation of the user's head, and mix the processed at least one channel with a sound received through the microphone (220) and output the result through the speaker (230). Through this operation, the positioning performance of the sound received from the electronic device (100) may be improved. For example, the processor (240) may enhance the positioning performance by providing a surround channel based on the rotation of the second electronic device (200) and the orientation of the user's head. Here, the information about the orientation of the head may include information about the up-down angle of the head.

[0131] When the processor (240) receives location information of the second electronic device (200) from the electronic device (100) through the communication interface (210), it processes the sound received through the microphone (220) based on the location information, mixes at least one channel and the processed sound, and outputs it through the speaker (230).

[0132] The second electronic device (200) further includes a user interface, and when a user command is received through the user interface, the processor (240) controls the communication interface (210) to transmit the user command to the electronic device (100) and perform an operation corresponding to the user command. For example, when a turn-off command is received, the processor (240) controls the communication interface (210) to transmit the turn-off command to the electronic device (100) and turn off the second electronic device (200).

[0133] The processor (240) may perform an operation to supplement the low-frequency range based on the specifications of the second electronic device (200). For example, the processor (240) may transmit a signal requesting the electronic device (100) to output the low-frequency range based on the specifications of the second electronic device (200). For example, if a signal received from the electronic device (100) includes a woofer channel, the processor (240) may transmit a signal requesting the electronic device (100) to output the woofer channel based on the specifications of the second electronic device (200). In this case, the second electronic device (200) may output the woofer channel, and the electronic device (100) may also output the woofer channel. However, the output of the woofer channel of the electronic device (100) may be lower than the output of the original signal, thereby providing the user with sound with reinforced low-frequency range while reducing inter-floor noise.

[0134] However, the present invention is not limited thereto, and the processor (240) may perform an operation to supplement the low-bandwidth based on the specifications of the second electronic device (200) through a device other than the electronic device (100). For example, the processor (240) may transmit a signal requesting the output of the low-bandwidth based on the specifications of the second electronic device (200) to another device connected to the same network as the second electronic device (200).

[0135] Hereinafter, the operation of the electronic device (100) will be described in more detail with reference to FIGS. 5 and 6. For convenience of explanation, individual embodiments are described in FIGS. 5 and 6. However, the individual embodiments of FIGS. 5 and 6 may be implemented in any combination.

[0136] FIG. 5 is a drawing for explaining the operation of an electronic system (1000) according to one embodiment of the present disclosure.

[0137] An electronic system (1000) may include an electronic device (100) and other electronic devices (200-1, 200-2).

[0138] The processor (130) of the electronic device (100) can receive sound from the TV and output the received sound through the speaker (110), as shown in FIG. 5.

[0139] While the processor (130) outputs sound, if it is identified that another electronic device (200-1, 200-2) is connected to the electronic device (100), it can identify whether a preset function is activated in the other electronic device (200-1, 200-2).

[0140] The processor (130) controls the communication interface (120) to transmit a preset channel among a plurality of channels to the other electronic device (200-1, 200-2) when a preset function is activated in the other electronic device (200-1, 200-2), and outputs the remaining channels except for at least one channel among the plurality of channels through the speaker (110). Here, the preset channel may include a woofer channel.

[0141] The processor (240) of the other electronic device (200-1, 200-2) can receive at least one channel from the electronic device (100) through the communication interface (210) and receive the remaining channels output by the speaker (110) of the electronic device (100) through the microphone (220).

[0142] The processor (240) can mix at least one channel and the remaining channels and output them through the speaker (230).

[0143] That is, the electronic device (100) can minimize damage to the surroundings by outputting the remaining channels except for channels that may cause inter-floor noise, such as the woofer channel.

[0144] The other electronic devices (200-1, 200-2) mix the woofer channel and the remaining channels output by the electronic device (100) and provide them to the user, so that the user can hear the sound of all channels, thereby providing the user with a sense of immersion and three-dimensionality.

[0145] FIG. 6 is a drawing for explaining sound processing of another electronic device (200-1, 200-2) according to one embodiment of the present disclosure.

[0146] The processor (240) of the other electronic device (200-1, 200-2) can receive at least one channel from the electronic device (100) through the communication interface (210). At this time, the electronic device (100) can output the remaining channels except for at least one channel through the speaker (110), and the processor (240) can receive the remaining channels through the microphone (220).

[0147] The processor (240) may signal-process at least one channel received through the communication interface (210) and signal-process the remaining channels received through the microphone (220). Here, at least one channel may be a portion of data of the original sound, and the remaining channels may be, for example, a mixed state in which an L channel and an R channel are output through the speaker (110). In addition, the remaining channels received through the microphone (220) may further include noise surrounding the second electronic device (200). Accordingly, the processor (240) may signal-process the at least one channel and the remaining channels in different ways.

[0148] The processor (240) can obtain a first signal to be output from the first body (200-1) and a second signal to be output from the second body (200-2) by mixing at least one signal-processed channel and the remaining signal-processed channels, and can amplify each of the first signal and the second signal and provide them to the corresponding body for output.

[0149] FIG. 7 is a flowchart for explaining a control method of an electronic device according to an embodiment of the present disclosure.

[0150] First, if another electronic device is identified as being connected to the electronic device, it is determined whether a preset function on the other electronic device is activated (S710). Then, based on whether the function is activated, at least one channel among the multiple channels included in the sound is transmitted to the other electronic device (S720).

[0151] In addition, the transmitting step (S720) may transmit a preset channel among multiple channels to the other electronic device when a preset function is activated in the other electronic device, and may transmit multiple channels to the other electronic device when the preset function is not activated in the other electronic device.

[0152] Additionally, the preset channels may include a woofer channel.

[0153] Additionally, when transmitting at least one channel to another electronic device, the method may further include a step of outputting the remaining channels, excluding at least one channel among the plurality of channels, through a speaker.

[0154] And, in the identifying step (S710), when another electronic device is identified as being connected to the electronic device, a signal is transmitted to the other electronic device to inquire whether a preset function is activated, and whether activation is determined based on a signal received from the other electronic device.

[0155] Additionally, the step of transmitting a signal may identify whether the other electronic device supports a preset function based on specification information of the other electronic device, and if the other electronic device supports the preset function, transmit a signal to the other electronic device to inquire whether the preset function is activated.

[0156] And, the transmitting step (S720) can transmit a signal below a preset frequency that makes negative positioning impossible in at least one channel to another electronic device, and output a signal above a preset frequency that makes negative positioning possible in at least one channel through a speaker.

[0157] Additionally, the transmitting step (S720) may compensate for at least one of the level or latency of at least one channel, and transmit the compensated at least one channel to another electronic device.

[0158] And, it further includes a step of identifying the location of the other electronic device, and the transmitting step can compensate for latency based on the location of the other electronic device.

[0159] In one embodiment, the method further comprises the step of outputting an inaudible sound through a speaker, wherein the transmitting step can compensate for latency based on delay information when delay information is received from another electronic device.

[0160] Additionally, the preset function may be a function of mixing sound received through a microphone of another electronic device with at least one channel received from the electronic device and outputting the sound through a speaker of the other electronic device.

[0161] And, in the identifying step (S710), when another electronic device is identified as being connected to the electronic device while outputting sound through the speaker of the electronic device, it is possible to identify whether a preset function is activated in the other electronic device.
