[0163] Although the electronic device (100) in the present disclosure is described as including a projection unit (112), the electronic device (100) may not include a projection unit (112). The electronic device (100) may provide content that includes only an audio signal without outputting a projection image.

[0164] FIG. 3 is a block diagram illustrating a specific configuration of the electronic device (100) of FIG. 2 according to one or more embodiments.

[0165] Referring to FIG. 3, the electronic device (100) may include at least one of a processor (111), a projection unit (112), a memory (113), a communication interface (114), an operation interface (115), an input / output interface (116), a speaker (117), a microphone (118), a power supply unit (119), a driving unit (120), a sensor unit (121), or a moving member (122).

[0166] The configuration illustrated in Fig. 3 is merely an example of various embodiments, and some configurations may be omitted and new configurations may be added. The contents already described in Fig. 2 are omitted.

[0167] At least one processor (111) may be implemented as a digital signal processor (DSP), a microprocessor, or a time controller (TCON) that processes a digital signal. However, the present invention is not limited thereto, and may include one or more of a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a graphics-processing unit (GPU), a communication processor (CP), or an advanced reduced instruction set computer (RISC) machines (ARM) processor, or may be defined by the relevant terminology. At least one processor (111) may be implemented as a system on chip (SoC) having a built-in processing algorithm, a large scale integration (LSI), or may be implemented in the form of a field programmable gate array (FPGA). At least one processor (111) may perform various functions by executing computer executable instructions stored in a memory (113).

[0168] The projection unit (112) may be configured to project an image externally. According to various embodiments of the present disclosure, the projection unit (112) may be implemented in various projection methods (e.g., a CRT (cathode-ray tube) method, an LCD (Liquid Crystal Display) method, a DLP (Digital Light Processing) method, a laser method, etc.). As one or more examples, the CRT method has the same principle as a CRT monitor. The CRT method magnifies the image with a lens in front of the cathode-ray tube (CRT) and displays the image on the screen. Depending on the number of cathode-ray tubes, it is divided into a single-tube type and a three-tube type, and in the case of a three-tube type, the red, green, and blue cathode-ray tubes may be implemented separately.

[0169] Another example is the LCD method, which displays images by passing light from a light source through liquid crystals. LCD methods are divided into single-panel and three-panel types. In the case of the three-panel type, light from a light source is separated into red, green, and blue by a dichroic mirror (a mirror that reflects only a specific color of light and transmits all others). After passing through the liquid crystals, the light can be refocused into a single point.

[0170] Another example is the DLP method, which displays images using a DMD (Digital Micromirror Device) chip. The DLP projection unit may include a light source, a color wheel, a DMD chip, a projection lens, etc. The light output from the light source can be colored as it passes through the rotating color wheel. The light passing through the color wheel is input to the DMD chip. The DMD chip contains numerous micromirrors and reflects the light input to the DMD chip. The projection lens can play a role in magnifying the light reflected from the DMD chip to the image size.

[0171] Another example is a laser system that uses a Diode Pumped Solid State (DPSS) laser and a galvanometer. A multi-color laser uses three DPSS lasers, one for each RGB color, with their optical axes overlapped by a special mirror. The galvanometer includes a mirror and a high-power motor that moves the mirror at high speeds. For example, the galvanometer can rotate the mirror at up to 40 kHz / sec. The galvanometer is mounted according to the scan direction, but since projectors typically scan in a planar manner, the galvanometer can also be positioned separately along the x and y axes.

[0172] As one or more examples, the projection unit (112) may include various types of light sources. For example, the projection unit (112) may include at least one light source from among a lamp, an LED, and a laser.

[0173] The projection unit (112) can output images in a 4:3 screen ratio, a 5:4 screen ratio, or a 16:9 wide screen ratio depending on the purpose of the electronic device (100) or the user's settings, and can output images in various resolutions such as WVGA (854*480), SVGA (800*600), XGA (1024*768), WXGA (1280*720), WXGA (1280*800), SXGA (1280*1024), UXGA (1600*1200), and Full HD (1920*1080) depending on the screen ratio.

[0174] As one or more examples, the projection unit (112) may perform various functions for adjusting the output image under the control of at least one processor (111). For example, the projection unit (112) may perform zoom, keystone, quick corner (4 corner) keystone, lens shift, or other suitable projector functions known in the art.

[0175] As one or more examples, the projection unit (112) can enlarge or reduce the image depending on the distance from the screen (projection distance). That is, a zoom function can be performed depending on the distance from the screen. At this time, the zoom function may include a hardware method of adjusting the screen size by moving the lens and a software method of adjusting the screen size by cropping the image or other appropriate adjustment methods known in the art. When the zoom function is performed, the focus of the image needs to be adjusted. For example, methods of adjusting the focus include a manual focus method, an electric focus method, etc. The manual focus method refers to a method of focusing manually, and the electric focus method refers to a method of automatically focusing using a motor built into the projector when the zoom function is performed. When performing the zoom function, the projection unit (112) may provide a digital zoom function through software, and may provide an optical zoom function of performing the zoom function by moving the lens through the driving unit (120).

[0176] As one or more examples, the projection unit (112) can perform a keystone correction function. For example, if the height is not right for front projection, the screen may be distorted upwards or downwards. The keystone correction function refers to a function that corrects a distorted screen. For example, if distortion occurs in the left and right directions of the screen, it can be corrected using horizontal keystone, and if distortion occurs in the up and down directions, it can be corrected using vertical keystone. The quick corner (4 corner) keystone correction function is a function that corrects the screen when the center area of ​​the screen is normal but the corner areas are not balanced. The lens shift function is a function that moves the screen as it is when the screen is off the screen.

[0177] As one or more examples, the projection unit (112) can automatically analyze the surrounding environment and projection environment without user input to provide zoom / keystone / focus functions. Specifically, the projection unit (112) can automatically provide zoom / keystone / focus functions based on the distance between the electronic device (100) and the screen detected through a sensor (depth camera, distance sensor, infrared sensor, light sensor, etc.), information about the space in which the electronic device (100) is currently located, information about the amount of ambient light, etc.

[0178] The projection unit (112) can provide a lighting function using a light source. For example, the projection unit (112) can provide a lighting function by outputting a light source using an LED. According to various embodiments, the projection unit (112) can include one LED, and according to other embodiments, the electronic device (100) can include a plurality of LEDs. As one or more examples, the projection unit (112) can output a light source using a surface-emitting LED according to an implementation example. As one or more examples, the surface-emitting LED can mean an LED having a structure in which an optical sheet is arranged on the upper side of the LED so that the light source is evenly distributed and output. Specifically, when a light source is output through the LED, the light source can be evenly distributed through the optical sheet, and the light source distributed through the optical sheet can be incident on the display panel.

[0179] As one or more examples, the projection unit (112) may provide a user with a dimming function for adjusting the intensity of the light source. Specifically, when a user input for adjusting the intensity of the light source is received from the user through the operation interface (115) (e.g., a touch display button or dial), the projection unit (112) may control the LED to output the intensity of the light source corresponding to the received user input.

[0180] The projection unit (112) can provide a dimming function based on content analyzed by at least one processor (111) without user input. Specifically, the projection unit (112) can control the LED to output the intensity of a light source based on information about the currently provided content (e.g., content type, content brightness, etc.).

[0181] As one or more examples, the projection unit (112) can control the color temperature under the control of at least one processor (111). As one or more examples, the at least one processor (111) can control the color temperature based on the content. Specifically, when the content is identified to be output, the at least one processor (111) can obtain frame-by-frame color information of the content whose output has been determined. Then, the at least one processor (111) can control the color temperature based on the obtained frame-by-frame color information. The at least one processor (111) can obtain at least one primary color of the frame based on the frame-by-frame color information. Then, the at least one processor (111) can adjust the color temperature based on the obtained at least one primary color. For example, the color temperature that the at least one processor (111) can adjust can be classified into a warm type or a cold type. As one or more examples, it is assumed that a frame to be output (hereinafter, referred to as an output frame) includes a scene in which a fire has occurred. At least one processor (111) can identify (or obtain) that the primary color is red based on color information included in the current output frame. In addition, at least one processor (111) can identify a color temperature corresponding to the identified primary color (red). The color temperature corresponding to red may be a warm type. At least one processor (111) can use an artificial intelligence model to obtain the color information or primary color of the frame. According to various embodiments, the artificial intelligence model can be stored in the electronic device (100) (e.g., the memory (113)). According to another embodiment, the artificial intelligence model can be stored in an external server that can communicate with the electronic device (100).

[0182] The memory (113) may be implemented as an internal memory such as a ROM (e.g., an electrically erasable programmable read-only memory (EEPROM)) or RAM included in at least one processor (111), or may be implemented as a separate memory from at least one processor (111). In this case, the memory (113) may be implemented as a memory embedded in the electronic device (100) or as a memory detachable from the electronic device (100) depending on the purpose of data storage. For example, data for driving the electronic device (100) may be stored in a memory embedded in the electronic device (100), and data for expanding functions of the electronic device (100) may be stored in a memory detachable from the electronic device (100).

[0183] In the case of memory embedded in the electronic device (100), it is implemented as at least one of volatile memory (e.g., dynamic RAM (DRAM), static RAM (SRAM), or synchronous dynamic RAM (SDRAM)), non-volatile memory (e.g., one time programmable ROM (OTPROM), programmable ROM (PROM), erasable and programmable ROM (EPROM), electrically erasable and programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (e.g., NAND flash or NOR flash), hard drive, or solid state drive (SSD)), and in the case of memory that can be attached or detached to the electronic device (100), it is implemented as at least one of memory card (e.g., compact flash (CF), secure digital (SD), micro secure digital (Micro-SD), mini secure digital (Mini-SD), extreme digital (xD), multi-media card (MMC), etc.), external memory that can be connected to a USB port (e.g., USB memory), or other suitable memory known by the conventional art. It can be implemented in the same form as the structure.

[0184] The memory (113) may store at least one command regarding the electronic device (100). In addition, the memory (113) may store an O / S (Operating System) for driving the electronic device (100). The memory (113) may also store various software programs or applications for operating the electronic device (100) according to various embodiments of the present disclosure. In addition, the memory (113) may include a semiconductor memory such as a flash memory, a magnetic storage medium such as a hard disk, or other suitable memory structures known in the art.

[0185] For example, various software modules for operating the electronic device (100) according to various embodiments of the present disclosure may be stored in the memory (113), and at least one processor (111) may control the operation of the electronic device (100) by executing various software modules stored in the memory (113). That is, the memory (113) is accessed by at least one processor (111), and data reading / recording / modifying / deleting / updating, etc. may be performed by at least one processor (111).

[0186] In the present disclosure, the term memory (113) may be used to mean a storage unit, a ROM, a RAM within at least one processor (111), or a memory card (e.g., a micro SD card, a memory stick) mounted on an electronic device (100).

[0187] The communication interface (114) may be configured to communicate with various types of external devices according to various types of communication methods. The communication interface (114) may include a wireless communication module or a wired communication module. Each communication module may be implemented in the form of at least one hardware chip.

[0188] A wireless communication module may be a module that communicates wirelessly with an external device. For example, the wireless communication module may include at least one of a Wi-Fi module, a Bluetooth module, an infrared communication module, or other communication modules.

[0189] Wi-Fi and Bluetooth modules can communicate via Wi-Fi and Bluetooth, respectively. When using a Wi-Fi or Bluetooth module, various connection information, such as the service set identifier (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.

[0190] Infrared communication modules perform communication based on infrared communication (IrDA, infrared Data Association) technology, which transmits data wirelessly over short distances using infrared light, which is between visible light and millimeter waves.

[0191] In addition to the above-described communication method, other communication modules 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.

[0193] The manipulation interface (115) may include various types of input devices. For example, the manipulation interface (115) may include a physical button. In this case, the physical button may include a function key, a directional key (e.g., a four-way key), or a dial button. According to various embodiments, the physical button may be implemented as multiple keys. According to another embodiment, the physical button may be implemented as one key. When the physical button is implemented as one key, the electronic device (100) may receive a user input in which one key is pressed for a threshold time or longer. When a user input in which one key is pressed for a threshold time or longer is received, at least one processor (111) may perform a function corresponding to the user input. For example, at least one processor (111) may provide a lighting function based on the user input.

[0194] The manipulation interface (115) can receive user input using a non-contact method. When receiving user input using a contact method, physical force must be transmitted to the electronic device (100). Therefore, a method for controlling the electronic device (100) regardless of physical force may be required. Specifically, the manipulation interface (115) can receive user gestures and perform operations corresponding to the received user gestures. The manipulation interface (115) can receive user gestures through a sensor (e.g., an image sensor or an infrared sensor).

[0195] The manipulation interface (115) can receive user input using a touch method. For example, the manipulation interface (115) can be implemented as a touch screen or a touch sensor, and the manipulation interface (115) can receive user input through the touch screen or the touch sensor. According to various embodiments, the touch method can be implemented in a non-contact manner. For example, the touch sensor can determine whether the user's body has approached within a threshold distance.

[0298] After the number of terminal devices (200) is identified, the electronic device (100) can request the location of the identified terminal devices (200) (S1135). The electronic device (100) can transmit a communication packet requesting the location of the terminal devices (200) to the terminal devices (200).

[0302] The electronic device (100) can determine the target location of the terminal device (200) by additionally considering the current location of the terminal device (200).

[0303] According to various embodiments, the electronic device (100) may identify the candidate location closest to the location of the terminal device (200) (the fourth location) among a plurality of candidate locations as the target location.

[0304] The electronic device (100) can identify multiple candidate locations when determining a target location. One of the multiple candidate locations can be selected. One location can be determined based on priority or other suitable criteria among the multiple candidate locations. Descriptions related to the multiple candidate locations are provided in FIGS. 19, 22, and 23.

[0305] The electronic device (100) can identify whether there are multiple candidate locations when determining a target location.

[0306] For example, if there are no multiple candidate locations, the electronic device (100) may identify the target location without considering the location of the terminal device (200) (fourth location).

[0307] When multiple candidate locations exist, the electronic device (100) can identify a target location by considering the location (fourth location) of the terminal device (200). The electronic device (100) can determine the candidate location closest to the location (fourth location) of the terminal device (200) among the multiple candidate locations as the target location.

[0308] Once the target location is determined, steps S1150, S1160, S1170, and S1175 may be performed.

[0309] FIG. 12 is a flowchart illustrating an operation of identifying a target location using performance information of a terminal device (200), according to one or more embodiments.

[0310] Steps S1210, S1220, S1225, S1226, S1230, S1250, S1260, and S1275 of FIG. 12 may correspond to steps S510, S520, S525, S526, S530, S550, S560, and S575 of FIG. 5, respectively. Duplicate explanations are omitted.

A description thereof is provided in FIG. 13.

[0313] The terminal device (200) can receive a request for audio performance information from the electronic device (100). In response to the request, the terminal device (200) can transmit the audio performance information to the electronic device (100) (S1228).

[0317] The electronic device (100) can determine the target location based on the first location, the second location, the third location, the number of terminal devices (200), and audio performance information (S1240).

[0318] As one or more examples, the audio performance information may include information indicating the output performance of a speaker (speaker output information). The electronic device (100) may determine the target location of the terminal device (200) based on the output performance. The better the output performance, the further away the target location may be from the electronic device (100).

[0319] As one or more examples, the audio performance information may include information indicating whether the woofer function is performed (woofer function information).

[0330] Speaker output power information can indicate the maximum electrical signal the speaker can handle. The higher the output value (e.g., watts), the louder the speaker can output.

[0331] Woofer function information can indicate whether the speaker is capable of performing woofer function.

[0332] Table (1300) may include audio performance information of devices connected to the electronic device (100).

[0335] The electronic device (100) can determine a frequency setting used to output an audio signal of a specific frequency band from the terminal device (200) based on the woofer information included in the audio performance information. The frequency setting can be included in the audio setting.

[0336] Output size settings may vary depending on the frequency band, and output size settings according to the frequency band may be described as EQ settings. EQ settings may be included in the frequency settings.

[0337] FIG. 14 is a flowchart illustrating an operation of recording an audio signal and changing audio settings according to one or more embodiments.

[0338] Steps S1450 and S1460 of Fig. 14 may correspond to steps S1250 and S1260 of Fig. 12, respectively. Duplicate explanations are omitted.

[0339] The audio settings described in Figure 12 are described as the first audio settings.

[0340] After providing guide information, the electronic device (100) can obtain first audio information including an audio signal and a first audio setting. The electronic device (100) can transmit the first audio information to the terminal device (200) (S1470).

[0341] The terminal device (200) can receive first audio information. The terminal device (200) can obtain an audio signal and a first audio setting from the first audio information. The terminal device (200) can output an audio signal based on the first audio setting (S1475).

[0342] After transmitting the first audio information to the terminal device (200), the electronic device (100) can perform an operation of recording an ambient audio signal. After the audio signal is output from the terminal device (200) based on the first audio setting, the electronic device (100) can record the audio signal output from the terminal device (200).

[0343] The electronic device (100) can obtain audio data that records an audio signal output from a terminal device (200) (S1480). The electronic device (100) can change the first audio setting to the second audio setting based on the audio data.

[0344] The electronic device (100) can determine whether the recorded audio signal corresponds to the audio signal transmitted from the electronic device (100).

[0345] The first audio setting may include a speaker output level setting. As one or more examples, assume that the output level setting is a first level. The electronic device (100) may transmit audio information for outputting an audio signal at the first level to the terminal device (200). When the audio signal is output from the terminal device (200) at the first level, the electronic device (100) may predict the level at which the audio signal is measured at the location of the electronic device (100). The electronic device (100) may obtain the expected level as a prediction result.

[0346] To obtain the expected level, the electronic device (100) may perform the operations included in the embodiment of FIG. 11. The electronic device (100) may obtain the location (fourth location) of the terminal device (200). The electronic device (100) may obtain the expected level based on the location (first location) of the electronic device (100), the location (fourth location) of the terminal device (200), and the first level.

[0347] According to various embodiments, the first position and the fourth position may be used as relative distances. The electronic device (100) may obtain distance information from the first position to the position (fourth position) of the terminal device (200). For example, the position (fourth position) of the terminal device (200) may indicate the distance the terminal device (200) is from the electronic device (100).

[0348] An audio signal may decrease in intensity as it travels from the output location to the measurement location. The greater the distance between the output location and the measurement location, the greater the decrease in intensity of the audio signal.

[0349] The electronic device (100) can predict the intensity of an audio signal based on a preset function. The preset function may be a function that calculates the rate of decrease of an audio signal over distance. The preset function may vary depending on the output size of the audio signal (the intensity output at the initial point in time). The electronic device (100) can obtain an expected level as a prediction result.

[0350] An electronic device (100) can record an audio signal output from a terminal device (200) to obtain audio data. The electronic device (100) can obtain the intensity of an audio signal included in the audio data as a measurement level.

[0351] The electronic device (100) can compare the expected level and the measured level.

[0352] Based on the difference between the expected level and the measured level, the electronic device (100) can determine whether to change the audio settings.

[0353] As one or more examples, if the difference between the measured level and the expected level is greater than or equal to a first threshold value (positive), the electronic device (100) may change the audio settings (EQ settings) so that the audio signal is output at a second level that is lower than the first level.

[0354] As one or more examples, if the difference between the measured level and the expected level is less than a second threshold (negative), the electronic device (100) may change the audio settings (EQ settings) so that the audio signal is output at a third level greater than the first level.

[0355] As one or more examples, if the difference between the measured level and the expected level is less than a first threshold (positive) or greater than a second threshold (negative), the electronic device (100) may maintain the first level. The electronic device (100) may not change the audio settings.

[0356] The electronic device (100) can change the first audio setting (first level) to the second audio setting (second level or third level) based on the comparison result.

[0357] The electronic device (100) can maintain the first audio setting (first level) based on the comparison result.

[0358] The electronic device (100) can obtain second audio information including an audio signal and second audio settings. The electronic device (100) can transmit the second audio information to a terminal device (200) (S1490).

[0359] As with the first audio information, the audio signal and the second audio settings may be transmitted to the terminal device (200) in separate communication packets or in the same communication packet.

[0360] The terminal device (200) can receive second audio information. The terminal device (200) can obtain an audio signal and second audio settings included in the second audio information. The terminal device (200) can output an audio signal based on the second audio settings (S1495).

[0397] After identifying the number of terminal devices to be connected to the electronic device (100), the electronic device (100) can identify a target location based on the first location, the second location, the third location, the number of terminal devices, and audio performance information (S1745).

[0398] The target location may refer to the target location of the first terminal device (200-1) and the target location of the second terminal device (200-2). The target location of the first terminal device (200-1) may be described as the first target location, and the target location of the second terminal device (200-2) may be described as the second target location.

[0399] The first target position and the second target position of Fig. 15 and the first target position and the second target position of Fig. 17 may be determined according to different concepts. The embodiment of Fig. 15 may also be applied to Fig. 17. If the first target position of Fig. 17 changes, it may be described as the third target position, and if the second target position of Fig. 17 changes, it may be described as the fourth target position.

[0400] In one or more examples, the target location may vary based on audio performance information. For example, the target location may vary based on speaker output size information, woofer function information, or other suitable criteria. The electronic device (100) may determine a location further from the electronic device (100) as the target location as the speaker output size increases. The electronic device (100) may determine the target location so that the location of the terminal device capable of performing the woofer function is placed at a preset location (in front of the user location (second location)).

[0401] The electronic device (100) can provide guide information to guide the first terminal device (200-1) and the second terminal device (200-2) to be placed at the target location (S1750).

[0402] The electronic device (100) can obtain a first audio signal and a second audio signal based on target location and audio performance information (S1755).

[0403] The electronic device (100) can obtain a first audio signal based on a first target location and first audio performance information.

The electronic device (100) may obtain an audio signal based on the third position of the projection area (30) and the target position of the terminal device (200). The target position may be a position from which an audio signal is output.

[0406] The electronic device (100) can identify the relative position of the target location with respect to the projection area (30). For example, the relative position can be used to specify the distance and direction with respect to the projection area (30).

[0407] The electronic device (100) can identify a first embodiment in which the target location is located in front of the projection area (30).

[0408] The electronic device (100) can identify a second embodiment in which the target location is located on the right side of the projection area (30). The target location located on the right side of the projection area (30) may be located in the left area in the direction in which the user (20) looks at the projection area (30).

[0409] The electronic device (100) can identify a third embodiment in which the target location is located on the left side of the projection area (30). The target location located on the left side of the projection area (30) may be located in the right area in the direction in which the user (20) looks at the projection area (30).

[0412] According to one or more embodiments, the electronic device (100) may acquire channel information based on the third location and the target location, and acquire an audio signal based on the acquired channel information. The channel information may include information indicating which channel the terminal device is performing a function on.

[0413] For example, two channels may include a first channel (left channel) and a second channel (right channel). Channel information may include information indicating which channel each of the first terminal device (200-1) and the second terminal device (200-2) will output audio signals to.

[0414] Channel information may include information indicating that the first terminal device (200-1) operates on the first channel. Channel information may include information indicating that the second terminal device (200-2) operates on the second channel.

[0415] The electronic device (100) can obtain an audio signal by taking channel information into consideration.

[0416] When the first terminal device (200-1) is identified as corresponding to the first channel, the electronic device (100) can obtain a first audio signal corresponding to the first channel and transmit the first audio signal to the first terminal device (200-1).

[0418] According to one or more embodiments, the electronic device (100) may obtain an audio signal based on the third location, the target location, and the audio performance information.

[0419] The electronic device (100) can additionally utilize audio performance information to obtain an audio signal. For example, the audio performance information may include woofer function information. The electronic device (100) can provide an audio signal with an emphasized low-frequency band to a terminal device capable of performing a woofer function. The electronic device (100) can identify whether the terminal device (200) can perform the woofer function based on the audio performance information. If the terminal device (200) can perform the woofer function, the electronic device (100) can generate an audio signal corresponding to the woofer function.

[0420] An audio signal corresponding to a woofer function may represent an audio signal in which a preset frequency band (e.g., a low frequency band) is emphasized. An audio signal in which a preset frequency band is emphasized may include an audio signal in which a preset frequency band has a greater intensity (or amplitude) than a frequency band other than the preset frequency band.

[0421] The electronic device (100) can provide a general audio signal to a terminal device (200) that cannot perform a woofer function. The general audio signal can represent an audio signal in which a specific frequency band is not emphasized.

The electronic device (100) can obtain second channel information corresponding to the second terminal device (200-2) based on the second relative position. The electronic device (100) can obtain a second audio signal based on the second channel information and the second audio performance information.

[0427] The electronic device (100) can obtain audio settings based on the third location, target location, and audio performance information (S1756).

[0428] The electronic device (100) can obtain audio settings based on speaker output information included in the audio performance information. The electronic device (100) can determine an output size for outputting an audio signal by considering the speaker output performance. The electronic device (100) can determine a maximum output size value based on the speaker output information. The output size can be described as an audio signal intensity value, an audio signal magnitude value, an audio signal output value, or another suitable value.

[0429] The electronic device (100) can obtain audio settings based on woofer function information included in the audio performance information. The electronic device (100) can provide audio settings corresponding to the woofer function to a terminal device (200) capable of performing the woofer function.

[0430] Audio settings corresponding to the woofer function may include settings that apply the output size of a preset frequency band to be larger than the output size of a frequency band other than the preset frequency band.

[0431] For example, audio settings corresponding to a woofer function may include information that sets the output size of a first frequency band (a preset frequency band) to a first level and sets the output size of a second frequency band (different from the first frequency band) to a second level (smaller than the first level).

[0432] According to one or more embodiments, the electronic device (100) may obtain a first relative position of the first target position based on the third position.

[0434] According to one or more embodiments, the electronic device (100) may obtain channel information based on the third location and the target location, and obtain audio settings based on the obtained channel information and audio performance information.

[0435] The electronic device (100) can obtain a first relative position of the first target position based on the third position.

[0437] The electronic device (100) can determine an EQ (Equalizer) setting based on woofer function information included in the audio performance information. The electronic device (100) can apply an EQ setting to emphasize low sounds to a terminal device (200) capable of performing a woofer function. The electronic device (100) can identify an EQ setting that increases a gain value for a frequency band of a critical range. A first gain value for the frequency band of the critical range can be greater than a second gain value for the frequency band of the critical range. The critical range can represent a low-frequency band corresponding to low sounds.

[0438] According to one or more embodiments, the woofer function may be processed on the audio signal side. The woofer function may be processed on the audio signal itself, regardless of the audio settings.

[0439] According to one or more embodiments, the operation for the woofer function may be performed in terms of audio settings. Audio signals are transmitted equally to each terminal device, and the woofer function can be implemented through audio settings.

[0440] According to one or more embodiments, operations for the woofer function may be performed both on the audio signal and in the audio settings. Processing for the woofer function may be performed on the audio signal, and settings for the woofer function may also be applied in the audio settings.

[0441] In step S1760, it is determined whether the arrangement of terminal devices is completed. If the arrangement is completed, the process proceeds to step S1770-1, and if the arrangement is not completed, the process returns to step S1760 and waits until the arrangement of terminal devices is completed. In step S1770-1, the electronic device (100) transmits first audio information including a first audio signal and a first audio setting to the first terminal device (200-1). In step S1770-2, the electronic device (100) transmits second audio information including a first audio signal and a second audio setting to the second terminal device (200-2). In step S1755-1, the first terminal device (200-1) outputs the first audio signal based on the first audio setting. In step S1775-2, the second terminal device (200-2) outputs the second audio signal based on the second audio setting.

The electronic device (100) can identify a first distance (d1) between the first location (p1) and the second location (p2) within the first straight line (1801). The electronic device (100) can identify a location located at a distance (d1) from the second location (p2) on the first straight line (1801) as a target location (pt).

[0446] The electronic device (100) can identify a position that is a first distance (d1) away in the opposite direction of the first position (p1) based on the second position (p2) when determining the target position (pt).

[0447] The electronic device (100) can generate guide information to guide the terminal device (200) to be placed at a target location (pt) and provide the guide information.

[0451] The electronic device (100) can identify a plurality of candidate locations (pt1, pt2). Once the plurality of candidate locations (pt1, pt2) are identified, the electronic device (100) can identify a third location (p3) in the projection area (30). The electronic device (100) can identify a location (pt2) closer to the third location (p3) among the plurality of candidate locations (pt1, pt2) as an audio setting target location (pt).

[0452] The electronic device (100) can identify the number of candidate locations. The electronic device (100) can identify whether the number of candidate locations is greater than the number of terminal devices. If the number of candidate locations is greater than the number of terminal devices, the electronic device (100) can identify a third location (p3). The electronic device (100) can identify a candidate location closer to the third location (p3) as the final target location so that the number of target locations is equal to the number of terminal devices.

[0453] The electronic device (100) can identify the final target position (pt) as the second candidate position (pt2). In the embodiment of FIG. 19, the target position (pt) may be the same as the second candidate position (pt2) and the first position (p1).

[0454] The electronic device (100) can generate guide information to guide the terminal device (200) to be placed at a target location (pt) and provide the guide information.

[0455] According to various embodiments, the electronic device (100) may determine a position (pt2) further from a third position (p3) among a plurality of candidate positions (pt1, pt2) as the final target position (pt).

[0456] FIG. 20 is a drawing for explaining target locations of two terminal devices according to one or more embodiments.

[0457] The first straight line (2001), the first position (p1), the second position (p2), the first distance (d1), the first candidate position (pt1), and the second candidate position (pt2) of FIG. 20 may correspond to the first straight line (1901), the first position (p1), the second position (p2), the first distance (d1), the first candidate position (pt1), and the second candidate position (pt2) of FIG. 19, respectively.

[0458] According to one or more embodiments, embodiment (2000) of FIG. 20 illustrates a situation in which a first terminal device (200-1) and a second terminal device (200-2) are connected to an electronic device (100). The electronic device (100) may identify the number of terminal devices (200-1, 200-2) as 2.

[0459] The electronic device (100) can identify whether the number of terminal devices (200-1, 200-2) and the number of candidate locations (pt1, pt2) are the same. If the number of terminal devices (200-1, 200-2) and the number of candidate locations (pt1, pt2) are the same, the electronic device (100) can determine a target location so that the terminal device is placed at one of the candidate locations (pt1, pt2).

[0460] The electronic device (100) can determine a first target position (pt1) so that the first terminal device (200-1) is placed at the first candidate position (pt1). The electronic device (100) can determine a second target position (pt2) so that the second terminal device (200-2) is placed at the second candidate position (pt2).

[0461] When there are multiple candidate locations and multiple terminal devices, placement criteria for which terminal devices are to be placed in which locations may be stored in the electronic device (100). The placement criteria may be used to specify how to place the terminal devices to achieve a desired audio environment (e.g., surround sound).

[0462] According to one or more embodiments, the electronic device (100) may randomly place the terminal device at a candidate location.

[0463] According to one or more embodiments, the electronic device (100) may place the terminal device at the candidate location by matching the order in which the candidate locations are identified with the order in which they are connected to the electronic device (100). For example, if the first candidate location (pt1) is first identified during the calculation process and the device first connected to the electronic device (100) is the first terminal device (200-1), the electronic device (100) may determine the first target location (pt1) to place the first terminal device (200-1) at the first candidate location (pt1).

[0464] According to one or more embodiments, the electronic device (100) may place the terminal device at a candidate location based on at least one of a priority of the candidate location or a priority of the terminal device.

[0465] The electronic device (100) can assign a preset priority to a candidate location.

[0466] As one or more examples, the electronic device (100) may determine that the closer the candidate location is to the third location (P3), the higher the priority.

[0467] As one or more examples, the electronic device (100) may determine that the closer the candidate location is to the first location (P1), the higher the priority.

[0468] As one or more examples, the electronic device (100) may determine that a terminal device capable of performing a woofer function has a higher priority by analyzing audio performance information for each of a plurality of terminal devices.

[0470] The electronic device (100) can determine the target location of each terminal device by matching the priority of the candidate location with the priority of the terminal device.

[0471] For example, the electronic device (100) may give a first priority to a first candidate location (pt1) that is closer to a third location (P3) among a plurality of candidate locations (pt1, pt2), and give a second priority to the remaining second candidate location (pt2).

[0472] The electronic device (100) can give a first priority to a first terminal device (200-1) capable of performing a woofer function among multiple terminal devices (200-1, 200-2) and give a second priority to a second terminal device (200-2) that cannot perform a woofer function.

[0473] The electronic device (100) can determine a first target position (pt1) so that a first terminal device (200-1) of a first priority is placed at a first candidate position (pt1) of a first priority. The electronic device (100) can determine a second target position (pt2) so that a second terminal device (200-2) of a second priority is placed at a second candidate position (pt2) of a second priority.

[0474] The electronic device (100) can generate guide information to guide a first terminal device (200-1) to be placed at a first target location (pt1) and a second terminal device (200-2) to be placed at a second target location (pt2), and can provide the guide information.

The electronic device (100) can identify a plurality of candidate locations that are spaced apart by a first distance (d1) from the second location (P2) on the second straight line (2102).

[0479] The plurality of candidate locations may be a first candidate location (pt1) and a second candidate location (pt2). The electronic device (100) may determine the final target location so that one of the plurality of terminal devices (200-1, 200-2) is placed in each of the plurality of candidate locations (pt1, pt2).
