[0163] Various information identified (obtained or determined) in this disclosure can be set directly through user input. For example, audio settings applied to each terminal device 200 can be determined through user input.

[0164] Although electronic device 100 is described as including projector 112, electronic device 100 may not include projector 112. Electronic device 100 may provide content consisting only of audio signals without outputting a projected image.

[0165] Figure 3 It is used to explain according to one or more embodiments Figure 2 A block diagram showing the specific configuration of the electronic device 100.

[0166] refer to Figure 3 The electronic device 100 may include at least one of the following: a processor 111, a projector 112, a memory 113, a communication interface 114, a control interface 115, an input / output interface 116, a speaker 117, a microphone 118, a power supply 119, a driver 120, a sensor 121, or a moving part 122.

[0167] Figure 3 The configurations shown are merely example embodiments, and some configurations may be omitted, while new configurations may be added. (Already...) Figure 2 Those described in the text have been omitted.

[0168] At least one processor 111 may be implemented as a digital signal processor (DSP), microprocessor, or time controller (TCON) for processing digital signals. However, at least one processor 111 is not limited to these, and at least one processor 120 may include one or more of a central processing unit (CPU), microcontroller unit (MCU), microprocessor unit (MPU), controller, application processor (AP), graphics processing unit (GPU), communication processor (CP), and ARM (Reduced Instruction Set Computer (RISC)) processor, or may be defined by the corresponding term. At least one processor 111 may be implemented as a system-on-a-chip (SoC), large-scale integration (LSI), or field-programmable gate array (FPGA) with embedded processing algorithms. At least one processor 111 can perform various functions by executing computer-executable instructions stored in memory 113.

[0169] Projector 112 can be configured to project images to the outside. According to various embodiments, projector 112 can be implemented using various projection methods (e.g., cathode ray tube (CRT) methods, liquid crystal display (LCD) methods, digital light processing (DLP) methods, laser methods, etc.). For example, the CRT method has essentially the same principle as a CRT monitor. The CRT method uses a lens in front of a cathode ray tube (CRT) to magnify the image and display it on a screen. Depending on the number of cathode ray tubes, it is divided into 1-tube and 3-tube types. In the case of a 3-tube type, red, green, and blue cathode ray tubes can be implemented separately.

[0170] In another example, the LCD method transmits light from a light source onto a liquid crystal to display an image. LCD methods can be divided into single-panel and three-panel types. In the case of a three-panel type, light from a light source can be separated into red, green, and blue in a dichroic mirror (a mirror that reflects only light of a specific color while allowing the rest of the light to pass through), and then these lights can converge together after passing through the liquid crystal.

[0171] Another example is the DLP method, which uses a digital micromirror device (DMD) chip to display an image. A DLP projector can include a light source, a color wheel, a DMD chip, a projection lens, etc. Light emitted from the light source is colored as it passes through a rotating color wheel. After passing through the color wheel, the light is input to the DMD chip. The DMD chip includes numerous microscopes that reflect the light input to it. The projection lens can be used to magnify the light reflected from the DMD chip to the size of the image.

[0172] In another example, the laser method includes a diode-pumped solid-state (DPSS) laser and a galvanometer. Three DPSS lasers are mounted for each of the RGB colors, and their optical axes are then superimposed using a special mirror. The galvanometer comprises a mirror and a high-power motor, and the mirror is moved at high speed. For example, the galvanometer can rotate the mirror at speeds up to 40 kHz / s. The galvanometer is mounted according to the scanning direction, and since projectors typically perform planar scanning, the galvanometer can also be positioned separately along the x-axis and y-axis.

[0173] In one or more examples, projector 112 may include various types of light sources. For example, projector 112 may include at least one of lamps, LEDs, or lasers as a light source.

[0174] The projector 112 can output images in 4:3, 5:4, and 16:9 aspect ratios, and can output images at 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), Full HD (1920*1080), etc.) depending on the aspect ratio.

[0175] In one or more examples, the projector 112 may perform various functions under the control of at least one processor 111 to adjust the output image. For example, the projector 112 may perform functions such as zoom, keystone, fast angle (4-corner) keystone, lens shift, or any other suitable projector function known to those skilled in the art.

[0176] In one or more examples, the projector 112 can zoom in or out of the image based on the distance from the screen (projection distance). In other words, the projector 112 can perform a zoom function based on the distance from the screen. In this case, the zoom function can 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, etc. Simultaneously, when performing the zoom function, it is necessary to adjust the image focus. For example, the method of adjusting the focus can include a manual focusing method, an electric focusing method, or any other adjustment method known to those skilled in the art. A manual focusing method refers to a method of manually focusing, and an electric method refers to a method in which the projector automatically focuses using a built-in motor when performing the zoom function. When performing the zoom function, the projector 112 can provide digital zoom functionality via software and can perform the zoom function by providing optical zoom functionality by moving the lens via the driver 120.

[0177] In one or more examples, projector 112 can perform keystone correction. For example, if the height is unsuitable for frontal projection, the screen may be distorted upwards or downwards. Keystone correction refers to the function of correcting a distorted screen. For example, if the screen is distorted in the left-right direction, it can be corrected by using horizontal keystone correction, and if the screen is distorted in the up-down direction, it can be corrected by using vertical keystone correction. When the center area of ​​the screen is normal but the corner areas are unbalanced, the fast-angle (4-corner) keystone correction function corrects the screen. The lens shift function shifts the screen as is when the image is off-screen.

[0178] In one or more examples, projector 112 can automatically provide zoom / keystone distortion / focus functions by analyzing the surrounding environment and projection environment without user input. Specifically, projector 112 can automatically provide zoom / keystone distortion / focus functions based on the distance of electronic device 100 from the screen detected by sensors (depth camera, distance sensor, infrared sensor, illuminance sensor, etc.), information about the space where electronic device 100 is currently located, information about the amount of ambient light, etc.

[0179] Projector 112 can provide illumination using a light source. For example, projector 112 can provide illumination by using an LED to output a light source. According to various embodiments, projector 112 may include a single LED, and according to other embodiments, electronic device 100 may include multiple LEDs. According to one or more embodiments, projector 112 can use a surface-emitting LED to output a light source. In one or more examples, a surface-emitting LED can refer to an LED having a structure in which an optical sheet is arranged on the upper side of the LED such that the light source is uniformly distributed and output. Specifically, when the light source is output through an LED, the light source can be uniformly distributed through the optical sheet, and the light source distributed through the optical sheet can be incident on the display panel.

[0180] In one or more examples, projector 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 via a control interface 115 (e.g., a touch display button or dial), projector 112 may control the LED output to adjust the intensity of the light source corresponding to the received user input.

[0181] The projector 112 can provide dimming functionality based on content analyzed by at least one processor 111 without user input. Specifically, the projector 112 can control the intensity of the LED output light source based on information about the currently provided content (e.g., content type, content brightness, etc.).

[0182] In one or more examples, the projector 112 can control the color temperature under the control of at least one processor 111. In one or more examples, at least one processor 111 can control the color temperature based on the content. Specifically, when content to be output is identified, at least one processor 111 can obtain frame-by-frame color information of the content determined to be output. Subsequently, at least one processor 111 can control the color temperature based on the obtained frame-by-frame color information. At least one processor 111 can obtain at least one or more dominant colors of the frame based on the frame-by-frame color information. Furthermore, at least one processor 111 can adjust the color temperature based on the obtained at least one or more dominant colors. For example, the color temperature that can be adjusted by at least one processor 111 can be classified as warm or cool. In one or more examples, suppose the frame to be output (hereinafter referred to as the output frame) includes a scene of a fire. At least one processor 111 can identify (or obtain) that the dominant color is red based on the color information included in the current output frame. Then, at least one processor 111 can identify the color temperature corresponding to the identified dominant color (red). The color temperature corresponding to red can be warm. At least one processor 111 can use an artificial intelligence model to obtain color information or primary color of a frame. According to various embodiments, the artificial intelligence model can be stored in the electronic device 100 (e.g., memory 113). According to other embodiments, the artificial intelligence model can be stored in an external server capable of communicating with the electronic device 100.

[0183] The memory 113 can be implemented as an internal memory such as ROM (e.g., electrically erasable programmable read-only memory (EEPROM)) and RAM included in at least one processor 111, or it can be implemented as a separate memory. In this case, depending on the data storage purpose, the memory 113 can be implemented as a memory embedded in the electronic device 100 or as a memory removable from the electronic device 100. For example, in the case of data used to drive the electronic device 100, the data can be stored in the memory embedded in the electronic device 100, and in the case of data used for extended functions of the electronic device 100, the data can be stored in the memory removable from the electronic device 100.

[0184] The memory embedded in the electronic device 100 may be implemented as at least one of volatile memory (e.g., dynamic RAM (DRAM), static RAM (SRAM), or synchronous dynamic RAM (SDRAM)) or non-volatile memory (e.g., one-time programmable ROM (OTPROM), programmable ROM (PROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (e.g., NAND flash or NOR flash), hard disk drive, or solid-state drive (SSD)). Furthermore, removable memory from the electronic device 100 may be implemented as a memory card (e.g., compact flash (CF), secure digital (SD), micro-secure digital (Micro-SD), mini-secure digital (Mini-SD), extreme digital (xD), or multimedia card (MMC)), external memory connectable to a USB port (e.g., USB memory), or any other suitable memory structure known to those skilled in the art.

[0185] The memory 113 may store at least one instruction for the electronic device 100. Furthermore, the memory 113 may store an operating system (O / S) for operating 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 this disclosure. The memory 113 may include a semiconductor memory such as flash memory, or a magnetic storage medium such as a hard disk, or any other suitable memory structure known to those skilled in the art.

[0186] For example, memory 113 may store various software modules for operating electronic device 100 according to various embodiments of the present disclosure, and at least one processor 111 may control the operation of electronic device 100 by executing the various software modules stored in memory 113. In other words, memory 113 may be accessed by at least one processor 111, and data may be read / written / modified / deleted / updated by at least one processor 111.

[0187] In this disclosure, the term "memory 113" may be used for a storage device, ROM or RAM including at least one processor 111, or a memory card (e.g., a micro SD card, memory stick) installed in an electronic device 100.

[0188] The communication interface 114 can be configured to communicate with various types of external devices according to various communication methods. The communication interface 114 may include wireless or wired communication modules. Each communication module can be implemented as at least one hardware chip.

[0189] A wireless communication module can be a module that wirelessly performs communication with external devices. For example, a wireless communication module may include at least one of a Wi-Fi module, a Bluetooth module, an infrared communication module, or other communication modules.

[0190] Wi-Fi and Bluetooth modules can communicate using Wi-Fi and Bluetooth methods respectively. When using a Wi-Fi or Bluetooth module, various connection information such as SSID and session key are first sent and received, and various information can be sent and received after a communication connection is established.

[0191] The infrared communication module performs communication based on the Infrared Data Association (IrDA) communication technology, which uses infrared light, between visible light and millimeter waves, to wirelessly transmit data over short distances.

[0192] In addition to the communication methods described above, it may also include at least one communication chip that performs communication according to various wireless communication standards such as Zigbee, 3G, 3GPP, LTE, LTE-A, 4G, 5G, etc.

For example, a wired communication module may include at least one of a local area network (LAN) module, an Ethernet module, a twisted pair cable, a coaxial cable, a fiber optic cable, or an ultra-wideband (UWB) module.

[0194] The operating interface 115 may include various types of input devices. For example, the operating interface 115 may include physical buttons. In this case, physical buttons may include function keys, directional keys (e.g., 4-way keys), or dial buttons. According to various embodiments, physical buttons may be implemented as multiple keys. According to another embodiment, physical buttons may be implemented as a single key. When a physical button is implemented as a single key, the electronic device 100 may receive user input that one of the keys has been pressed for more than a threshold time. When user input that one of the keys has been pressed for more than the threshold time is received, at least one processor 111 may execute a function corresponding to the user input. For example, at least one processor 111 may provide a lighting function based on the user input.

[0195] The control interface 115 can receive user input using a contactless method. When receiving user input using a contact method, physical force must be applied to the electronic device 100. Therefore, a method for controlling the electronic device 100 regardless of the physical force may be required. Specifically, the control interface 115 can receive user gestures and perform operations corresponding to the received user gestures. The control interface 115 can receive user gestures via sensors (e.g., image sensors or infrared sensors).

[0196] The manipulation interface 115 can receive user input using a touch method. For example, the manipulation interface 115 can be implemented as a touchscreen or a touch sensor, wherein the manipulation interface 115 can receive user input via a touchscreen or touch sensor. According to various embodiments, the touch method can be implemented as a contactless method. For example, the touch sensor can determine whether the user's body is approaching within a threshold distance. The touch sensor can recognize user input even when the user is not touching the touch sensor. According to another implementation, the touch sensor can recognize user input when the user touches the touch sensor.

[0197] In one or more examples, electronic device 100 can receive user input in various ways other than using the aforementioned manipulation interface 115. In various embodiments, electronic device 100 can receive user input via an external remote control device. The external remote control device can be a remote control device corresponding to electronic device 100 (e.g., a dedicated control device for electronic device 100) or a user's portable communication device (e.g., a smartphone or wearable device). The user's portable communication device can store applications for controlling electronic device 100. The portable communication device can obtain user input through the stored applications and send the obtained user input to electronic device 100. Electronic device 100 can receive user input from the portable communication device and execute operations corresponding to the user's control commands.

[0198] In one or more examples, electronic device 100 can use speech recognition to receive user input. According to various embodiments, electronic device 100 can receive user speech via a microphone included in electronic device 100. According to another embodiment, electronic device 100 can receive user speech from a microphone or an external device. Specifically, an external device can acquire user speech via its microphone and send the acquired user speech to electronic device 100. The user speech sent from the external device can be audio data or digital data converted from audio data (e.g., audio data converted to the frequency domain, etc.). Electronic device 100 can perform operations corresponding to the received user speech. Specifically, electronic device 100 can receive audio data corresponding to user speech via its microphone. Furthermore, electronic device 100 can convert the received audio data into digital data. Additionally, electronic device 100 can use STT (Speech-to-Text) functionality to convert the converted digital data into text data. According to various embodiments, the STT function can be performed directly on electronic device 100.

[0199] According to another embodiment, STT (Speech-to-Text) functionality can be performed on an external server. Electronic device 100 can send digital data to the external server.

The UI 1040 may include at least one of the following: an item indicating the number of terminal devices 200, an item indicating the channel information implemented by the terminal device 200 (e.g., two channels), or an item indicating detailed channel information corresponding to the terminal device 200 (e.g., left channel, right channel).

[0296] When multiple terminal devices 200 constituting an audio environment exist, the electronic device 100 can provide a UI 1040 including detailed channel information corresponding to each of the multiple terminal devices 200. For example, as Figure 10 As shown, a stereo environment can be provided, wherein a first terminal device outputs the left channel and a second terminal device provides the right channel. In one or more examples, the audio settings for each of the connectable terminal devices can be configured such that the placement of the terminal device at the corresponding target location enables a surround sound environment.

[0297] Figure 11 This is a flowchart of an example operation for identifying a target location using the location of a terminal device 200 according to one or more embodiments.

[0298] Figure 11 Operations S1110, S1120, S1125, S1126, S1130, S1150, S1160, S1170, and S1175 can respectively correspond to Figure 5 Operations S510, S520, S525, S526, S530, S550, S560, S570, and S575. Redundant descriptions will be omitted.

[0299] After identifying the number of terminal devices 200, the electronic device 100 can request the location of the identified terminal devices 200 (S1135). The electronic device 100 can send a communication packet requesting the location of the terminal devices 200 to the terminal devices 200.

[0300] In one or more examples, terminal device 200 may receive a location request from electronic device 100. Terminal device 200 may send a response to the location request to electronic device 100 (S1136). Terminal device 200 may send a response to electronic device 100 indicating the location of terminal device 200. Terminal device 200 may send a communication packet to electronic device 100 including a response indicating the location of terminal device 200.

[0301] Electronic device 100 can receive a response from terminal device 200 indicating the location of terminal device 200. Electronic device 100 can obtain the location (fourth location) of terminal device 200 based on the response received from terminal device 200 (S1137).

[0302] The electronic device 100 can identify the target location based on at least one of the following: the location of the electronic device 100 (first location), the location of the user 20 (second location), the location of the projection area 30 (third location), or the location of the terminal device 200 (fourth location) (S1140).

[0303] The electronic device 100 can also take into account the current location of the terminal device 200 to determine the target location of the terminal device 200.

[0304] According to various embodiments, the electronic device 100 can identify the candidate position (fourth position) that is closest to the terminal device 200 among a plurality of candidate positions as the target position.

[0305] When determining a target location, the electronic device 100 can identify multiple candidate locations. One of the multiple candidate locations can be selected. The selection of the multiple candidate locations can be based on priority or any other suitable criteria. (See reference) Figure 19 , Figure 22 and Figure 23 Provides descriptions of multiple candidate locations.

[0306] When determining the target location, the electronic device 100 can identify whether there are multiple candidate locations.

[0307] In one or more examples, in the absence of multiple candidate locations, electronic device 100 can identify the target location without considering the location of terminal device 200 (the fourth location).

[0308] If multiple candidate locations exist, the electronic device 100 can identify the target location by considering the location of the terminal device 200 (the fourth location). The electronic device 100 can determine the candidate location that is closest to the location of the terminal device 200 (the fourth location) among the multiple candidate locations as the target location.

[0309] Once the target location is determined, operations S1150, S1160, S1170, and S1175 can be performed.

[0310] Figure 12 This is a flowchart of an example operation for identifying a target location using performance information from a terminal device 200 based on one or more embodiments.

[0311] Figure 12 Operations S1210, S1220, S1225, S1226, S1230, S1250, S1260, and S1275 can correspond to Figure 5 Operations S510, S520, S525, S526, S530, S550, S560, and S575. Redundant descriptions will be omitted.

[0312] After performing the scanning operation, the electronic device 100 may request audio performance information from the terminal device 200 (S1227). The audio performance information may include information indicating the performance of the speaker used when outputting the audio signal. The electronic device 100 may send a communication packet requesting the audio performance information to the terminal device 200.

[0313] Audio performance information may include at least one of the following: information indicating whether a speaker is included, information indicating the level of audio signal output (e.g., volume level), or information indicating whether a subwoofer function can be performed. Figure 13 This will be described.

[0314] Terminal device 200 can receive a request for audio performance information from electronic device 100. Terminal device 200 can respond to the request by sending the audio performance information to electronic device 100 (S1228). Terminal device 200 can also send a communication packet including the audio performance information to electronic device 100.

[0315] Electronic device 100 can receive audio performance information from terminal device 200. Electronic device 100 can identify the number of terminal devices 200 based on the audio performance information (S1230). Electronic device 100 can determine whether terminal device 200 is capable of outputting an audio signal based on the audio performance information of terminal device 200.

[0316] If the terminal device 200 does not have a speaker, it cannot output an audio signal. In one or more examples, the electronic device 100 may determine whether to select the terminal device 200 as a device for configuring the audio environment based on information included in the audio performance information of the terminal device 200 regarding whether the terminal device 200 includes a speaker (speaker presence information).

[0317] When it is identified that terminal device 200 does not include a speaker, electronic device 100 may not select terminal device 200. Electronic device 100 may exclude terminal device 200, which does not include a speaker, from the devices configuring the audio environment. In one or more examples, when terminal device 200 does not include a speaker, it may be indicated that terminal device 200 cannot be connected to electronic device 100 to prevent terminal device 200 from connecting to electronic device 100.

[0318] 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).

[0319] In one or more examples, audio performance information may include information indicating the output performance of a speaker (speaker output information). Electronic device 100 can determine the target location of terminal device 200 by taking the output performance into account. The better the output performance, the farther the target location can be from electronic device 100.

[0320] In one or more examples, the audio performance information may include information indicating whether the subwoofer function is executed (subwoofer function information). Electronic device 100 may determine that a target location for the terminal device 200 capable of executing the subwoofer function is arranged within a preset area. For example, electronic device 100 may determine a target location such that the terminal device 200 capable of executing the subwoofer function is arranged in front of the user 20. Electronic device 100 may determine a target location such that the terminal device 200 is arranged in a direction from a second location towards a first location.

[0321] Once the target location is determined, the electronic device 100 can provide guidance information to place the terminal device 200 at or near the target location (S1250).

[0322] After providing guidance information, the electronic device 100 can determine whether the terminal device 200 has been placed at the target location (S1260).

[0323] When the terminal device 200 is placed at the target location (S1260 - Yes), the electronic device 100 can generate audio information including audio signals and audio settings. The electronic device 100 can then send the audio information including audio signals and audio settings to the terminal device 200 (S1270). The electronic device 100 can send the audio information to the terminal device 200 in the form of communication packets.

[0324] According to various embodiments, the audio signal and audio settings can be sent to the terminal device 200 separately, and neither the audio signal nor the audio settings are included in the audio information. The electronic device 100 can send the audio signal and audio settings to the terminal device 200 based on separate communication packets. In one or more examples, the audio settings can be sent first, followed by the audio signal. This is because analyzing and applying the audio settings may take time.

[0325] Terminal device 200 can receive audio information from electronic device 100. Terminal device 200 can obtain audio signals and audio settings from the audio information. Electronic device 100 can output audio signals based on the audio settings.

[0326] For example, audio settings may include an output size setting for outputting audio signals. Terminal device 200 may output audio signals based on the output size setting.

[0327] Figure 13 This is a diagram of a table of example performance information according to one or more embodiments.

[0328] refer to Figure 13The electronic device 100 can obtain audio performance information for each of the connectable terminal devices 200. Table 1300 may include audio performance information for each of the connectable terminal devices 200.

[0329] Audio performance information may include at least one of speaker presence information, speaker output information, or subwoofer function information.

[0330] Speaker presence information can indicate whether or not a speaker is included.

[0331] Speaker output information indicates the maximum magnitude of an electrical signal that the speaker can process. The higher the output value (e.g., W), the louder the sound the speaker can produce.

[0332] Subwoofer function information indicates whether the speaker is capable of performing subwoofer functions.

[0333] Table 1300 may include audio performance information of devices connected to electronic device 100. Electronic device 100 may use the audio performance information for each audio device to configure the operation of the audio environment. As will be understood by those skilled in the art, Figure 13 The information provided is merely illustrative, and audio performance information may include any other suitable device audio characteristics known to those skilled in the art.

[0334] Electronic device 100 can determine whether terminal device 200 is a device capable of configuring an audio environment based on speaker presence information included in the audio performance information.

[0335] Electronic device 100 can determine the output size setting for outputting audio signals from terminal device 200 based on speaker output information included in audio performance information. The output size setting can be included in the audio settings.

[0336] Based on the subwoofer information included in the audio performance information, the electronic device 100 can determine the frequency setting for the terminal device 200 to output an audio signal in a specific frequency band. The frequency setting can be included in the audio settings.

[0337] Output size settings can vary depending on the frequency band, and output size settings based on the frequency band can be described as EQ settings. EQ settings can be included within frequency settings.

[0338] Figure 14 This is a flowchart illustrating an example operation of changing audio settings by recording audio signals, according to one or more embodiments.

[0339] Figure 14 Operations S1450 and S1460 can respectively correspond to Figure 12Operations S1250 and S1260. Redundant descriptions will be omitted.

[0340] Figure 12 The audio settings described in [the document] will be described as the first audio settings.

[0341] After providing guidance information, electronic device 100 can obtain first audio information including an audio signal and a first audio setting. Electronic device 100 can then send the first audio information to terminal device 200 (S1470).

[0342] Terminal device 200 can receive first audio information. Terminal device 200 can obtain an audio signal and a first audio setting from the first audio information. Terminal device 200 can output an audio signal based on the first audio setting (S1475).

[0343] After sending the first audio information to the terminal device 200, the electronic device 100 can perform the operation of recording ambient audio signals. After outputting an audio signal from the terminal device 200 based on the first audio settings, the electronic device 100 can record the audio signal output from the terminal device 200.

[0344] Electronic device 100 can acquire audio data, which is a record of an audio signal output from terminal device 200 (S1480). Electronic device 100 can change a first audio setting to a second audio setting based on the audio data.

[0345] The electronic device 100 can determine whether the recorded audio signal corresponds to the audio signal sent by the electronic device 100.

[0346] The first audio setting may include a speaker output level setting. In one or more examples, it is assumed that the output level setting is a first level. Electronic device 100 may send audio information to terminal device 200 for outputting an audio signal at the first level. When an audio signal is output from terminal device 200 at the first level, electronic device 100 may predict the measured level of the audio signal at the location of electronic device 100. Electronic device 100 may obtain the estimated level as a result of the prediction.

[0347] In order to obtain the estimated level, electronic device 100 can perform... Figure 11 The operation in the embodiments. For example, electronic device 100 can obtain the location (fourth location) of terminal device 200. Electronic device 100 can obtain an estimated level based on the location of electronic device 100 (first location), the location of terminal device 200 (fourth location), and the first level.

[0348] According to various embodiments, the first position and the fourth position can be used as relative distances. The electronic device 100 can obtain distance information to the position (fourth position) of the terminal device 200 by referring to the first position. For example, the position (fourth position) of the terminal device 200 can represent the distance of the terminal device 200 relative to the electronic device 100.

[0349] The intensity of an audio signal can decrease as it moves from the output position to the measurement position. The greater the distance between the output position and the measurement position, the weaker the audio signal may become.

[0350] Electronic device 100 can estimate the intensity of an audio signal based on a preset function. The preset function can be a function that calculates the rate of decrease of the audio signal based on distance. The preset function can be different for each output magnitude of the audio signal (e.g., the intensity output at the initial time point). Electronic device 100 can obtain the estimated level as a prediction result.

[0351] Electronic device 100 can acquire audio data by recording the audio signal output by terminal device 200. Electronic device 100 can obtain the intensity of the audio signal included in the audio data as a measurement level.

[0352] The electronic device 100 can compare the estimated level with the measured level.

[0353] Based on the difference between the estimated level and the measured level, the electronic device 100 can determine whether to change the audio settings.

[0354] In one or more examples, when the difference obtained by subtracting the estimated level from the measured level is equal to or greater than a first threshold (positive number), the electronic device 100 may change the audio settings (e.g., EQ settings) such that the audio signal is output at a second level less than the first level.

[0355] In one or more examples, when the difference obtained by subtracting the estimated level from the measured level is less than a second threshold (negative number), the electronic device 100 can change the audio settings (EQ settings) so that the audio signal is output at a third level greater than the first level.

[0356] In one or more examples, the electronic device 100 may maintain the first level when the difference obtained by subtracting the estimated level from the measured level is less than a first threshold (positive number) or equal to or greater than a second threshold (negative number). The electronic device 100 may not change the audio settings.

[0357] Based on the comparison results, the electronic device 100 can change the first audio setting (first level) to the second audio setting (second level or third level).

[0358] Electronic device 100 can maintain the first audio setting (first level) based on the comparison result.

[0359] Electronic device 100 can acquire second audio information, including an audio signal and a second audio setting. Electronic device 100 can send the second audio information to terminal device 200 (S1490).

[0360] Similar to the first audio information, the audio signal and the second audio settings can be sent to the terminal device 200 in a separate communication packet or in the same communication packet.

[0361] Terminal device 200 can receive second audio information. Terminal device 200 can obtain the audio signal and second audio settings included in the second audio information. Terminal device 200 can output an audio signal based on the second audio settings (S1495).

[0369] In one or more examples, when the difference obtained by subtracting the estimated level from the measured level is less than a second threshold (negative value), the electronic device 100 can determine that the third target location is closer to the electronic device 100 than the first target location.

[0370] In one or more examples, the electronic device 100 may maintain the first level when the difference obtained by subtracting the estimated level from the measured level is less than a first threshold (positive number) or equal to or greater than a second threshold (negative number).

[0376] When the target position is determined to be maintained, the electronic device 100 may not repeat operations S1560 to S1590.

[0377] When the absolute value of the difference obtained by subtracting the estimated level from the measured level is equal to or greater than the third threshold, the electronic device 100 can change the audio settings, such as... Figure 14 As shown in the embodiments.

[0378] When the absolute value of the difference obtained by subtracting the estimated level from the measured level is less than a third threshold, the electronic device 100 can change the target position, such as... Figure 15 As shown in the embodiments.

[0451] The electronic device 100 may have multiple positions on a first straight line 1801 that are a first distance d1 from the second position p2. The multiple positions may be a first candidate position pt1 and a second candidate position pt2.

[0452] The electronic device 100 can identify multiple candidate positions pt1 and pt2. Once the multiple candidate positions pt1 and pt2 are identified, the electronic device 100 can identify the third position p3 of the projection area 30.

[0472] For example, the electronic device 100 may assign a first priority to the first candidate position pt1, which is closer to the third position p3 among a plurality of candidate positions pt1 and pt2, and assign a second priority to the remaining second candidate positions pt2.

[0473] The electronic device 100 can assign a first priority to the first terminal device 200-1 among the multiple terminal devices 200-1 and 200-2 that can perform the subwoofer function, and assign a second priority to the second terminal device 200-2 that cannot perform the subwoofer function.

[0479] When there are two terminal devices, the electronic device 100 can identify an imaginary second straight line 2102 perpendicular to the first straight line 2101. The electronic device 100 can identify multiple candidate positions on the second straight line 2102 that are a first distance d1 from the second position p2, with reference to the second position p2.

[0480] The multiple candidate locations can be a first candidate location pt1 and a second candidate location pt2. The electronic device 100 can determine the final target location, such that multiple terminal devices 200-1 and 200-2 are respectively arranged at the multiple candidate locations pt1 and pt2.
