[0107] In one embodiment, the processor (450) may, in operation 525, determine a first output frequency range of an audio signal of the electronic device (101) based on first information related to a speaker (441) of the electronic device (101).

[0108] In one embodiment, the first output frequency range of the audio signal may include one of a low frequency range (e.g., a band of about 100 Hz to 299 Hz), a mid frequency range (e.g., a band of about 500 Hz to 2.9 kHz), and a high frequency range (e.g., a band of about 3 kHz to 6.9 kHz).

[0109] In one embodiment, the operation of checking the first output frequency range of the audio signal of the electronic device (101) may be an operation of determining the output type of the speaker (441) of the electronic device (101). For example, the output type of the speaker (441) may include a woofer that outputs a low-frequency audio signal, a midrange that outputs a mid-frequency audio signal, and a tweeter that outputs a high-frequency audio signal.

[0110] In one embodiment, the processor (450) may, in operation 530, determine a second output frequency range of an audio signal of an external electronic device based on second information related to a speaker of the external electronic device. For example, the second output frequency range of the audio signal may include one of a low frequency range (e.g., a band of about 100 Hz to 299 Hz), a mid frequency range (e.g., a band of about 500 Hz to 2.9 KHz), and a high frequency range (e.g., a band of about 3 KHz to 6.9 KHz).

[0111] In one embodiment, the operation of determining the second output frequency range of the audio signal of the external electronic device may be an operation of determining the output type of the speaker of the external electronic device. For example, the output type of the speaker of the external electronic device may include a woofer that outputs a low-frequency audio signal, a midrange that outputs a mid-frequency audio signal, and a tweeter that outputs a high-frequency audio signal.

[0112] In one embodiment, the first output frequency range of the audio signal of the electronic device (101) and the second output frequency range of the audio signal of the external electronic device may be different, but are not limited thereto.

[0113] In one embodiment, the processor (450) may compare first information related to the speaker (441) of the electronic device (101) with second information related to the speaker of the external electronic device, and, based on the comparison result, determine the first output frequency range of the audio signal of the electronic device (101) and the second output frequency range of the audio signal of the external electronic device. For example, the processor (450) may output an audio signal having a specified frequency through the speaker (441). For example, the audio signal having the specified frequency may include pink noise or white noise. In response to the audio signal having the specified frequency, the processor (450) may receive an output signal output through the speaker of the external electronic device through the microphone (443) of the electronic device (101). The processor (450) compares first information related to the speaker (441) of the electronic device (101) with an output signal received through the microphone (443), and based on the comparison result, can determine the first output sound range of the audio signal of the electronic device (101) and the second output sound range of the audio signal of the external electronic device.

[0114] In one embodiment, the processor (450) may output, in operation 535, an audio signal to which at least one first audio parameter corresponding to a first output frequency range of an audio signal of the electronic device (101) is applied through the speaker (441).

[0115] In one embodiment, the processor (450) may calibrate the audio signal by applying at least one first audio parameter corresponding to the first output frequency band to the audio signal. The processor (450) may output the audio signal of the calibrated first output frequency band through the speaker (441). For example, the at least one first audio parameter may include at least one of a low pass filter, a high pass filter, a band pass filter, a gain, an AGC, or mixing, but is not limited thereto.

[0116] The operation of correcting an audio signal by applying at least one first audio parameter corresponding to a first output frequency band to the aforementioned audio signal according to one embodiment may be performed in the audio signal processor (240) of FIG. 2, but is not limited thereto.

[0117] In one embodiment, the processor (450) can output an audio signal of a first output frequency range to which at least one first audio parameter is applied through the speaker (441).

[0118] In one embodiment, the processor (450) may transmit information related to the audio signal and the second output frequency band to an external electronic device through the communication circuit (410) while outputting an audio signal (e.g., an audio signal of a first output frequency band to which at least one first audio parameter is applied) through the speaker (441) in operation 540. For example, the processor (450) may transmit the information related to the audio signal and the second output frequency band to the external electronic device so that the external electronic device applies at least one second audio parameter corresponding to the second output frequency band (e.g., a low frequency band, a mid frequency band, or a high frequency band) of the identified audio signal to the audio signal and outputs the audio signal (e.g., outputs an audio signal of the second output frequency band). The at least one second audio parameter may include, but is not limited to, at least one of a low pass filter, a high pass filter, a band pass filter, a gain, an AGC, or mixing.

[0119] Not limited thereto, the processor (450) may apply at least one second audio parameter corresponding to the second output frequency range to the audio signal and transmit the same to an external electronic device. In this case, the external electronic device may output the audio signal to which at least one second audio parameter received from the electronic device (101) is applied through a speaker.

[0120] In one embodiment, although not shown, the processor (450) may display a user interface on the display (430) that includes information related to an audio signal, information related to a first output frequency range of the audio signal of the electronic device (101), and information related to a second output frequency range of the audio signal of the external electronic device.

[0121] In one embodiment, the processor (450) may provide a user interface that allows a user to select a second output frequency range (e.g., low frequency, mid frequency, or high frequency) of an audio signal of an external electronic device.

[0122] FIG. 6 is a diagram illustrating a signal flow between an electronic device (101) and an external electronic device (601) according to one embodiment of the present disclosure.

[0123] In the following embodiments, the operations of FIG. 6 may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations of FIG. 6 may be changed, and at least two operations may be performed in parallel.

[0124] Since operations 605 to 640 of FIG. 6 according to one embodiment are substantially the same as operations 505 to 540 of FIG. 5 described above, a detailed description thereof may be replaced with the description of FIG. 5.

[0125] Referring to FIG. 6, an electronic device (e.g., an electronic device (101) of FIG. 1) (e.g., a processor of the electronic device (101) (e.g., a processor (450) of FIG. 4)) may output an audio signal through a speaker (e.g., a speaker (441) of FIG. 4) in operation 605. For example, the electronic device (101) may output an audio signal stored in a memory of the electronic device (101) (e.g., a memory (420) of FIG. 4), an image stored in an external storage device (e.g., an SD device), or a streaming audio signal provided from an external electronic device or server. However, the present invention is not limited thereto.

[0126] In one embodiment, the electronic device (101) may establish a communication connection with the external electronic device (601) in operation 615 based on detecting an external electronic device (601) (e.g., at least one external electronic device (310) of FIG. 3) in proximity to the electronic device (101) in operation 610. For example, the electronic device (101) may establish a communication connection with the external electronic device (601) in proximity within a specified distance using short-range wireless communication (e.g., UWB, Bluetooth, or low-power Bluetooth). In one embodiment, the external electronic device (601) may include a device having an audio output circuit (e.g., a speaker) (e.g., a wireless audio output device (e.g., a Bluetooth speaker), a watch, a smart phone, a tablet PC, a desktop PC, a laptop PC, and / or a smart TV).

[0127] In one embodiment, the electronic device (101) may obtain first information related to the speaker (441) of the electronic device (101) in operation 617. The first information related to the speaker (441) of the electronic device (101) may include a frequency band related to the output of an audio signal supported by the speaker (441) of the electronic device (101).

[0128] In one embodiment, the electronic device (101) may obtain second information related to a speaker of the external electronic device (601) in operation 620. The second information related to the speaker of the external electronic device (601) may include a frequency band related to the output of an audio signal supported by the speaker of the external electronic device (601).

[0129] In one embodiment, the electronic device (101) may, in operation 625, determine a first output frequency range of an audio signal of the electronic device (101) based on first information related to a speaker (441) of the electronic device (101). The first output frequency range may include one of a low frequency range, a mid frequency range, and a high frequency range.

[0130] In one embodiment, the electronic device (101) may, in operation 630, determine a second output frequency range of an audio signal of the external electronic device (601) based on second information related to a speaker of the external electronic device (601). The second output frequency range may include one of a low frequency range, a mid frequency range, and a high frequency range.

[0131] In one embodiment, the first output frequency range and the second output frequency range may be different, but are not limited thereto.

[0132] Not limited thereto, the electronic device (101) according to one embodiment may compare first information related to the speaker (441) with second information related to the speaker of the external electronic device (601), and, based on the comparison result, determine the first output frequency range of the audio signal of the electronic device (101) and the second output frequency range of the audio signal of the external electronic device (601). For example, the processor (450) may output an audio signal (e.g., pink noise or white noise) having a specified frequency through the speaker (441). In response to the audio signal having the specified frequency, the electronic device (101) may receive an output signal output through the speaker of the external electronic device (601) through the microphone (443) of the electronic device (101). The electronic device (101) may compare first information related to the speaker (441) of the electronic device (101) with an output signal received through the microphone (443), and, based on the comparison result, may determine the first output sound range of the audio signal of the electronic device (101) and the second output sound range of the audio signal of the external electronic device (601).

[0133] In one embodiment, the electronic device (101) may output, in operation 635, an audio signal to which at least one first audio parameter corresponding to a first output frequency band of an audio signal of the electronic device (101) is applied, through the speaker (441). In one embodiment, the electronic device (101) may correct the audio signal by applying at least one first audio parameter corresponding to the first output frequency band to the audio signal, and output the audio signal of the corrected first output frequency band through the speaker (441). For example, the at least one first audio parameter may include at least one of a low pass filter, a high pass filter, a band pass filter, a gain, an AGC, or mixing. However, the present invention is not limited thereto.

[0134] In one embodiment, it is assumed that the first output frequency range of the audio signal of the electronic device (101) is determined as a low frequency range. In this case, the processor (450) can perform audio signal processing that applies a low pass filter to the audio signal and increases the gain of the audio signal to which the low pass filter is applied. Based on performing audio signal processing that applies the low pass filter and increases the gain to the audio signal, the processor (450) can cause the low frequency range audio signal to be output through the speaker (441) (e.g., the speaker (441) operates as a woofer speaker). As another example, it is assumed that the first output frequency range of the audio signal of the electronic device (101) is determined as a mid frequency range. In this case, the processor (450) can perform audio signal processing that applies a band pass filter to the audio signal and increases the gain of the audio signal to which the band pass filter is applied. Based on performing audio signal processing that increases the band-pass filter and gain on the audio signal, the processor (450) can cause the mid-range audio signal to be output through the speaker (441) (e.g., the speaker (441) operates as a mid-range speaker). As another example, it will be described assuming that the first output range of the audio signal of the electronic device (101) is determined as a high-range range. In this case, the processor (450) can perform audio signal processing that applies a high-pass filter to the audio signal and increases the gain of the audio signal to which the high-pass filter is applied. Based on performing audio signal processing that applies a high-pass filter and increases the gain on the audio signal, the processor (450) can cause the high-range audio signal to be output through the speaker (441) (e.g., the speaker (441) operates as a tweeter speaker). The present invention is not limited thereto, and the processor (450) may also perform audio signal processing that mono-mixes the audio signal and then increases the gain.

[0135] In one embodiment, while outputting an audio signal (e.g., an audio signal to which at least one first audio parameter corresponding to a first output frequency band is applied) through a speaker (441), the electronic device (101) may, in operation 640, transmit information related to the audio signal and the second output frequency band to an external electronic device (601).

[0136] In one embodiment, the external electronic device (601) may determine at least one second audio parameter corresponding to the second output audio range based on information related to the second output audio range received from the electronic device (101) in operation 645. For example, the at least one second audio parameter may include at least one of a low pass filter, a high pass filter, a band pass filter, a gain, an AGC, or mixing, but is not limited thereto.

[0137] In one embodiment, the external electronic device (601) may apply at least one second audio parameter corresponding to the determined second output sound frequency range to the audio signal and output the audio signal through the speaker in operation 650. For example, the external electronic device (601) may correct the audio signal by applying at least one second audio parameter corresponding to the second output sound frequency range to the audio signal, and output the audio signal of the corrected second output sound frequency range through the speaker.

[0138] In one embodiment, the description will be made assuming that the second output frequency range of the audio signal is determined as a low frequency range. In this case, the external electronic device (601) can perform audio signal processing that applies a low-pass filter to the audio signal and increases the gain of the audio signal to which the low-pass filter is applied. Based on performing audio signal processing that applies the low-pass filter and increases the gain to the audio signal, the external electronic device (601) can cause the low-frequency audio signal to be output through the speaker (e.g., the speaker of the external electronic device (601) operates as a woofer speaker). As another example, the description will be made assuming that the first output frequency range of the audio signal is determined as a mid-frequency range. In this case, the external electronic device (601) can perform audio signal processing that applies a band-pass filter to the audio signal and increases the gain of the audio signal to which the band-pass filter is applied. Based on performing audio signal processing that increases a band-pass filter and gain on an audio signal, the external electronic device (601) can cause a mid-range audio signal to be output through a speaker (e.g., the speaker of the external electronic device (601) operates as a mid-range speaker). As another example, it will be described assuming that the first output range of the audio signal is determined as a high-range range. In this case, the external electronic device (601) can perform audio signal processing that applies a high-pass filter to the audio signal and increases the gain of the audio signal to which the high-pass filter is applied. Based on performing audio signal processing that applies a high-pass filter and increases the gain on the audio signal, the external electronic device (601) can cause a high-range audio signal to be output through a speaker (e.g., the speaker of the external electronic device (601) operates as a tweeter speaker). The present invention is not limited thereto, and the external electronic device (601) may also perform audio signal processing that mono-mixes an audio signal and then increases the gain.

[0139] Not limited thereto, the electronic device (101) may correct the audio signal by applying at least one second audio parameter corresponding to the second output sound frequency range to the audio signal, and transmit the corrected audio signal of the second output sound frequency range to the external electronic device (601). In this case, the external electronic device (601) may output the corrected audio signal of the second output sound frequency range received from the electronic device (101) (e.g., an audio signal of a low-pitched sound frequency range, an audio signal of a mid-pitched sound frequency range, or an audio signal of a high-pitched sound frequency range) through a speaker.

[0141] In the following embodiments, the operations of FIGS. 7A and 7B may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations of FIGS. 7A and 7B may be changed, and at least two operations may be performed in parallel.

[0142] Referring to FIGS. 7A and 7B, an electronic device (e.g., the electronic device (101) of FIG. 1) (e.g., a processor of the electronic device (101) (e.g., the processor (450) of FIG. 4)) may output an audio signal through a speaker (e.g., the speaker (441) of FIG. 4) in operation 705. For example, the electronic device (101) may output an audio signal stored in a memory of the electronic device (e.g., the memory (420) of FIG. 4), an image stored in an external storage device (e.g., an SD device), or a streaming audio signal provided from an external electronic device or server. However, the present invention is not limited thereto.

[0143] In one embodiment, the electronic device (101) may, based on detecting a plurality of external electronic devices (e.g., a first external electronic device (701), a second external electronic device (703)) in proximity to the electronic device (101) in operation 710, establish a communication connection with the first external electronic device (701) in operation 715, and establish a communication connection with the second external electronic device (703) in operation 720. For example, the electronic device (101) may establish a communication connection with the first external electronic device (701) and the second external electronic device (703) that are in proximity within a specified distance using short-range wireless communication (e.g., UWB, Bluetooth, or low-power Bluetooth). In one embodiment, the first external electronic device (701) and the second external electronic device (703) may include a device having audio output circuitry (e.g., a speaker) (e.g., a wireless audio output device (e.g., a Bluetooth speaker), a watch, a smart phone, a tablet PC, a desktop PC, a laptop PC, and / or a smart TV).

The third information related to the speaker of the second external electronic device (703) may include a frequency band related to the output of an audio signal supported by the speaker of the second external electronic device (703).

[0146] In one embodiment, the electronic device (101) may, in operation 735, determine a first output frequency range of an audio signal of the electronic device (101) based on first information related to a speaker (441) of the electronic device (101). The first output frequency range may include one of a low frequency range, a mid frequency range, and a high frequency range.

[0147] In one embodiment, the electronic device (101) may, in operation 740, determine a second output frequency range of an audio signal of the first external electronic device (701) based on second information related to a speaker of the first external electronic device (701).

[0148] In one embodiment, the electronic device (101) may, in operation 745, determine a third output frequency range of an audio signal of the second external electronic device (703) based on third information related to a speaker of the second external electronic device (703). The third output frequency range may include one of a low frequency range, a mid frequency range, and a high frequency range.

[0149] In one embodiment, the first output range, the second output range, and the third output range may be different, but are not limited thereto.

[0150] Not limited thereto, the electronic device (101) according to one embodiment may compare first information related to the speaker (441), second information related to the speaker of the first external electronic device (701), and third information related to the speaker of the second external electronic device (703), and, based on the comparison result, determine the first output frequency range of the audio signal of the electronic device (101), the second output frequency range of the audio signal of the first external electronic device (701), and the third output frequency range of the audio signal of the second external electronic device (703). For example, the processor (450) may output an audio signal (e.g., pink noise or white noise) having a specified frequency through the speaker (441). In response to the audio signal having the specified frequency, the electronic device (101) may receive an output signal output through the speaker of the first external electronic device (701) through the microphone (443) of the electronic device (101). Additionally, in response to an audio signal having a specified frequency, the electronic device (101) can receive an output signal output through a speaker of a second external electronic device (703) through a microphone (443) of the electronic device (101). The electronic device (101) can compare first information related to the speaker (441) of the electronic device (101), an output signal output through the speaker of the first external electronic device (701) received through the microphone (443), and an output signal output through the speaker of the second external electronic device (703).

[0151] In one embodiment, the electronic device (101) may output, in operation 750, an audio signal to which at least one first audio parameter corresponding to a first output frequency band of an audio signal of the electronic device (101) is applied, through the speaker (441). In one embodiment, the electronic device (101) may correct the audio signal by applying at least one first audio parameter corresponding to the first output frequency band to the audio signal, and output the audio signal of the corrected first output frequency band through the speaker (441). For example, the at least one first audio parameter may include at least one of a low pass filter, a high pass filter, a band pass filter, a gain, an AGC, or mixing. However, the present invention is not limited thereto.

[0152] In one embodiment, the electronic device (101) may transmit, in operation 755, information related to an audio signal and a second output sound frequency to a first external electronic device (701). In operation 760, the electronic device (101) may transmit, in operation 760, information related to an audio signal and a third output sound frequency to a second external electronic device (703).

[0153] In one embodiment, the first external electronic device (701) may determine at least one second audio parameter corresponding to the second output sound frequency range based on information related to the second output sound frequency range received from the electronic device (101) in operation 765. For example, the at least one second audio parameter may include at least one of a low pass filter, a high pass filter, a band pass filter, a gain, an AGC, or mixing. However, the present invention is not limited thereto. In operation 770, the first external electronic device (701) may apply the at least one second audio parameter corresponding to the determined second output sound frequency range to an audio signal and output the audio signal through a speaker. For example, the first external electronic device (701) may correct the audio signal by applying the at least one second audio parameter corresponding to the second output sound frequency range to the audio signal, and output the audio signal of the corrected second output sound frequency range through the speaker.

[0154] In one embodiment, the second external electronic device (703) may determine at least one third audio parameter corresponding to the third output sound frequency band based on information related to the third output sound frequency band received from the electronic device (101) in operation 775. For example, the at least one third audio parameter may include at least one of a low pass filter, a high pass filter, a band pass filter, a gain, an AGC, or mixing.

In operation 780, the second external electronic device (703) may apply the at least one third audio parameter corresponding to the determined third output sound frequency band to an audio signal and output the audio signal of the corrected third output sound frequency band through the speaker. For example, the second external electronic device (703) may correct the audio signal by applying the at least one third audio parameter corresponding to the third output sound frequency band to the audio signal, and output the audio signal of the corrected third output sound frequency band through the speaker.

[0155] Not limited thereto, the electronic device (101) may correct the audio signal by applying at least one second audio parameter corresponding to the second output sound frequency range to the audio signal, and transmit the audio signal of the corrected second output sound frequency range to the first external electronic device (701).

By outputting an audio signal of a first output range optimized for the speaker (441) through the speaker (441) of the electronic device (101), and outputting an audio signal of a second output range or a third output range optimized for the speaker of at least one external electronic device (310, 601, 701, 703) that is communicatively connected to the electronic device (101), the sound performance can be improved. In addition, based on the first information related to the speaker (441) of the electronic device (101) and the information (e.g., second information or third information) related to the speaker of at least one external electronic device (310, 601, 701, 703) that is communicably connected to the electronic device (101), audio signals of different output frequency ranges are reproduced, thereby increasing the reproduction frequency band range of the audio signal to provide optimal (e.g., improved) sound performance, as well as providing a spatial sound effect.

The processor (450) may establish a communication connection with the first external electronic device (811) based on detection of a first external electronic device (811) (e.g., at least one external electronic device (310) of FIG. 3, an external electronic device (601) of FIG. 6, a first external electronic device (701) of FIGS. 7A and 7B) approaching the electronic device (101) through a communication circuit (e.g., a communication circuit (410) of FIG. 4). The first external electronic device (811) may include a device having an audio output circuit (e.g., a speaker) (e.g., a wireless audio output device (e.g., a Bluetooth speaker), a watch, a smart phone, a tablet PC, a desktop PC, a laptop PC, and / or a smart TV).

[0159] In one embodiment, the processor (450) can determine a first output sound range (e.g., low-pitched sound, mid-pitched sound, or high-pitched sound) of an audio signal of the electronic device (101) based on first information related to the speaker (441) of the electronic device (101) (e.g., an output sound pressure level of the speaker (441) of the electronic device (101).

[0160] In one embodiment, the processor (450) may determine second information related to a speaker of a first external electronic device (811) connected to the communication (e.g., an output sound pressure level of the speaker of the first external electronic device (811)), and determine a second output sound range (e.g., a low-pitched sound range, a mid-pitched sound range, or a high-pitched sound range) of an audio signal of the first external electronic device (811) based on the second information.

[0161] Not limited thereto, the processor (450) may compare the first information related to the speaker (441) of the electronic device (101) with the second information related to the speaker of the first external electronic device (811), and, based on the comparison result, determine the first output frequency range of the audio signal of the electronic device (101) and the second output frequency range of the audio signal of the first external electronic device (811). For example, the processor (450) may output an audio signal (e.g., pink noise or white noise) having a specified frequency through the speaker (441). In response to the audio signal having the specified frequency, the processor (450) may receive an output signal output through the speaker of the first external electronic device (811) through the microphone (443). The processor (450) compares first information related to the speaker (441) of the electronic device (101) with an output signal (e.g., an output signal output through the speaker of the first external electronic device (811)) received through the microphone (443), and based on the comparison result, can determine the first output sound range of the audio signal of the electronic device (101) and the second output sound range of the audio signal of the first external electronic device (811).

[0162] In one embodiment, the first output frequency range and the second output frequency range may be different, but are not limited thereto.

[0163] In FIG. 8 according to one embodiment, the first output range of the audio signal of the electronic device (101) is assumed to be a high range, and the second output range of the audio signal of the first external electronic device (811) is assumed to be a low range.

[0164] In one embodiment, the processor (450) may correct the audio signal by applying at least one first audio parameter corresponding to the high-pitched sound range, which is a first output sound range, to the audio signal, and output the corrected high-pitched sound signal through the speaker (441). For example, the at least one first audio parameter may include at least one of a low-pass filter, a high-pass filter, a band-pass filter, a gain, an AGC, or mixing. For example, the processor (450) may perform audio signal processing to apply a high-pass filter to the audio signal and increase the gain of the audio signal to which the high-pass filter is applied. Based on performing the audio signal processing to increase the high-pass filter and the gain on the audio signal, the processor (450) may cause the high-pitched sound signal to be output through the speaker (441) (e.g., the speaker (441) operates as a tweeter speaker).

[0165] In one embodiment, while outputting an audio signal (e.g., a high-pitched audio signal) through a speaker (441), the processor (450) may transmit the audio signal and information related to a second output pitch range to a first external electronic device (811). The first external electronic device (811) may determine at least one second audio parameter corresponding to a low-pitched audio signal, which is the second output pitch range, based on the information related to the second output pitch range received from the electronic device (101). The first external electronic device (811) may correct the audio signal by applying the at least one second audio parameter corresponding to the low-pitched audio signal, which is the second output pitch range, to the audio signal, and output the corrected low-pitched audio signal through the speaker. For example, the at least one second audio parameter may include at least one of a low-pass filter, a high-pass filter, a band-pass filter, a gain, an AGC, or mixing. For example, the first external electronic device (811) may perform audio signal processing that applies a low-pass filter to an audio signal and increases the gain of the audio signal to which the low-pass filter has been applied. Based on performing audio signal processing that applies the low-pass filter and increases the gain to the audio signal, the first external electronic device (811) may cause a low-frequency audio signal to be output through a speaker (e.g., the speaker of the first external electronic device (811) operates as a woofer speaker).

[0166] Not limited thereto, the processor (450) may correct the audio signal by applying at least one second audio parameter corresponding to the low-pitched range, which is the second output sound range, to the audio signal, and transmit the corrected low-pitched range audio signal to the first external electronic device (811). The first external electronic device (811) may output the corrected low-pitched range audio signal received from the electronic device (101) through a speaker.

[0167] FIG. 8 according to various embodiments <810> In , the electronic device (101) is described as being connected to a single external electronic device (e.g., the first external electronic device (811)), but is not limited thereto. The electronic device (101) may be connected to a plurality of external electronic devices (e.g., 811, 851). For example, in FIG. 8 <850> As illustrated, the processor (450) can communicate with a second external electronic device (851) (e.g., the second external electronic device (703) of FIGS. 7A and 7B) in proximity to the electronic device (101) through a communication circuit (410). The second external electronic device (851) can include a device having an audio output circuit (e.g., a speaker).

[0168] In one embodiment, the processor (450) may check third information related to a speaker of a second external electronic device (851) connected to the communication (e.g., an output sound pressure level of the speaker of the second external electronic device (851)) and determine a third output sound range (e.g., a low-pitched sound range, a mid-pitched sound range, or a high-pitched sound range) of an audio signal of the second external electronic device (851) based on the third information. The processor (450) may transmit information related to the audio signal and the third output sound range of the determined audio signal to the second external electronic device (851).

[0169] Not limited thereto, the processor (450) may compare the first information related to the speaker (441) of the electronic device (101), the second information related to the speaker of the first external electronic device (811), and the third information related to the speaker of the second external electronic device (851). Based on the comparison result, the processor (450) may identify the first output sound range of the audio signal of the electronic device (101), the second output sound range of the audio signal of the first external electronic device (811), and the third output sound range of the audio signal of the second external electronic device (851). For example, the processor (450) may output an audio signal (e.g., pink noise or white noise) having a specified frequency through the speaker (441). In response to an audio signal having a specified frequency, the processor (450) can receive, through the microphone (443), an output signal output through the speaker of the first external electronic device (811) and an output signal output through the speaker of the second external electronic device (851). The processor (450) can compare first information related to the speaker (441) of the electronic device (101) and output signals received through the microphone (443) (e.g., an output signal output through the speaker of the first external electronic device (811) and an output signal output through the speaker of the second external electronic device (851), and, based on the comparison result, can identify a first output frequency range of the audio signal of the electronic device (101), a second output frequency range of the audio signal of the first external electronic device (811), and a third output frequency range of the audio signal of the second external electronic device (851).

[0170] In one embodiment, the first output range, the second output range, and the third output range may be different, but are not limited thereto.

[0171] In FIG. 8 according to one embodiment, the third output frequency range of the audio signal of the second external electronic device (851) is assumed to be a mid-frequency range and explained.

[0172] In one embodiment, the second external electronic device (851) may determine at least one third audio parameter corresponding to the mid-range, which is the third output range, based on information related to the third output range of the audio signal received from the electronic device (101). The second external electronic device (851) may correct the audio signal by applying the at least one third audio parameter corresponding to the mid-range, which is the third output range, to the audio signal, and output the corrected mid-range audio signal through the speaker. For example, the at least one third audio parameter may include at least one of a low-pass filter, a high-pass filter, a band-pass filter, a gain, an AGC, or mixing. For example, the second external electronic device (851) may perform audio signal processing by applying a band-pass filter to the audio signal and increasing the gain of the audio signal to which the band-pass filter is applied. Based on performing audio signal processing that increases the band pass filter and gain on the audio signal, the second external electronic device (851) can cause the audio signal in the mid-range range to be output through the speaker (e.g., the speaker of the second external electronic device (851) operates as a mid-range speaker).

[0173] Not limited thereto, the processor (450) may correct the audio signal by applying at least one third audio parameter corresponding to the mid-range, which is the third output sound range, to the audio signal, and transmit the corrected mid-range audio signal to the second external electronic device (851). The second external electronic device (851) may output the corrected mid-range audio signal received from the electronic device (101) through a speaker.

[0174] In one embodiment, although not shown, the processor (450) may display a user interface on a display (e.g., display (430) of FIG. 4) that includes information related to an audio signal, information related to a first output frequency band of the audio signal of the electronic device (101), information related to a second output frequency band of the audio signal of the first external electronic device (811), and / or information related to a third output frequency band of the audio signal of the second external electronic device (851).

[0175] In one embodiment, the processor (450) may provide a user interface that enables selection (or change) of a first output frequency range of an audio signal of the electronic device (101), a second output frequency range of an audio signal of the first external electronic device (811), and / or a third output frequency range of an audio signal of the second external electronic device (851).

[0176] In one embodiment, the processor (450) may receive a second audio signal (e.g., a low-range audio signal) output through a speaker of the first external electronic device (811) and / or a third audio signal (e.g., a mid-range audio signal) output through a speaker of the second external electronic device (851) through a microphone (e.g., the microphone (443) of FIG. 4). The processor (450) may estimate a relative position of the first external electronic device (811) and / or the second external electronic device (851) with respect to the electronic device (101) based on the magnitude of the received second audio signal and / or the magnitude of the third audio signal. The first external electronic device (811) and / or the second external electronic device (851) may also receive the size of an audio signal output through the speaker (411) of the electronic device (101) via a microphone, and may estimate the relative position of the electronic device (101) based on the size of the audio signal output through the speaker (411) of the electronic device (101). The first external electronic device (811) and / or the second external electronic device (851) may transmit information related to the estimated relative position of the electronic device (101) to the electronic device (101).

[0177] In one embodiment, the processor (450) may display a user interface on the display (430) that includes information for guiding the placement position of the electronic device (101) and / or the first external electronic device (811) based on the estimated relative position of the first external electronic device (811), information related to the first output sound range (e.g., high sound range), information related to the second output sound range (e.g., low sound range), and / or information related to the relative position of the electronic device (101) received from the first external electronic device (811). According to one embodiment, the user interface may further include information for guiding the placement position of the second external electronic device (851) based on the estimated relative position of the second external electronic device (851), information related to the third output sound range (e.g., mid sound range), and / or information related to the relative position of the electronic device (101) received from the second external electronic device (851). For example, a first external electronic device (811) that outputs a low-pitched audio signal can be guided to be positioned in a direction (e.g., center, middle area) that the user (801) is looking at, based on the user (801). As another example, an electronic device (101) that outputs a high-pitched audio signal can be guided to be positioned relatively farther away from the user (801) than other electronic devices (e.g., the first external electronic device (811) and the second external electronic device (851)). The electronic device (101), the first external electronic device (811), and the second external electronic device (851) estimate the relative positions of each other, and guide positions appropriate for the output pitch range based on the relative positions, thereby allowing audio signals with a greater sense of space to be played.

[0178] In one embodiment, when the electronic device (101) is connected to at least two external electronic devices (e.g., a first external electronic device (811) and a second external electronic device (851)), a multi-channel (e.g., 3.1 channel, 5.1 channel, or 7.1 channel) audio signal can be played back through the speaker of the electronic device (101) and the speakers of each of the at least two external electronic devices (e.g., the first external electronic device (811) and the second external electronic device (851)), thereby providing a three-dimensional sound effect to the user.

[0179] In one embodiment, the electronic device (101) can detect ambient noise information. If the noise level based on the detected ambient noise information exceeds a specified value, the electronic device (101) can perform compensation to increase an audio signal of a specific band. The audio signal of the specific band may include one of an audio signal output through the speaker (441) of the electronic device (101) or an audio signal output through the speaker of at least one external electronic device. For example, the audio signal of the specific band may include a human voice signal (e.g., an audio signal in a mid-range). However, the present invention is not limited thereto. In one embodiment, if the audio signal of the specific band is an audio signal output through the speaker (441) of the electronic device (101), the electronic device (101) can apply at least one audio parameter that increases the level of the audio signal of the specific band to compensate for the audio signal of the specific band and output it through the speaker (441). Alternatively, if the audio signal of a specific band is an audio signal output through a speaker of at least one electronic device, the electronic device (101) may transmit information related to correction of the audio signal of the specific band to at least one external electronic device. The at least one external electronic device may correct the audio signal of the specific band and output it through the speaker based on the information related to correction of the audio signal of the specific band received from the electronic device (101). In one embodiment, if ambient noise information is detected, the electronic device (101) may perform correction to increase the size of the audio signal of the specific band, thereby allowing the electronic device (101) or the at least one external electronic device to output the corrected audio signal of the specific band, thereby improving the sound quality of the audio signal of the specific band.Additionally, the electronic device (101) can perform compensation to increase the size of an audio signal of a specific band, thereby enabling a user to hear an audio signal of a specific band even in a noisy situation.

[0180] In one embodiment, when at least one external electronic device in communication with the electronic device (101) includes a microphone, the at least one external electronic device can be used as an input device (e.g., a voice recognition device) to control at least one function being performed by the electronic device (101).

[0181] In one embodiment, the electronic device (101) may include a wearable electronic device. The wearable electronic device may include augmented reality (AR) glasses in the form of glasses, smart glasses, a head mounted display (HMD), or video see-through mixed reality (VST MR). In one embodiment, the user (801) may be wearing the wearable electronic device. When the user (801) is wearing the wearable electronic device, the wearable electronic device outputs an audio signal of a first output sound range through a speaker of the wearable electronic device, and additionally outputs an audio signal of a second output sound range (or a third output sound range) different from the first output sound range through at least one external electronic device connected to the wearable electronic device, thereby providing the user with a realistic and spatial sound.
