[0029] Figure 1 This is a diagram illustrating an example electrical system according to various embodiments.

[0030] Reference Figure 1 The electronic system may include a first electronic device 101, a second electronic device 102, a third electronic device 104, and a fourth electronic device 108. For example, each of the first electronic device 101, the second electronic device 102, the third electronic device 104, and the fourth electronic device 108 can send / receive data to / from another via a short-range communication technology (e.g., Bluetooth communication technology). For example, the first electronic device 101 and the second electronic device 102 can send / receive data using wireless communication technology. The first electronic device 101 can directly send / receive data to / from the third electronic device 104 and / or the fourth electronic device 108. The second electronic device 102 can directly send / receive data to / from the third electronic device 104 and / or the fourth electronic device 108.

[0031] According to an embodiment, the first electronic device 101 and the second electronic device 102 can be implemented as headphones that wirelessly output sound. For example, the first electronic device 101 and the second electronic device 102 can convert data received from the fourth electronic device 108 into sound and output the converted sound (e.g., music). The first electronic device 101 and the second electronic device 102 can acquire external sound (e.g., a user's voice) and send data corresponding to the acquired sound to the fourth electronic device 108. For example, the first electronic device 101 and the second electronic device 102 can be implemented as being worn on the user's right ear and left ear, respectively. For example, the first electronic device 101 can be a main device (also called a main accessory), and the second electronic device 102 can be an auxiliary device (also called an auxiliary accessory). For example, the first electronic device 101 can form a communication link with the fourth electronic device 108. The first electronic device 101 can send information acquired by the first electronic device 101 and information received from the second electronic device 102 to the fourth electronic device 108 through the communication link.

[0032] According to an embodiment, the first electronic device 101 and the second electronic device 102 can be mounted on a third electronic device 104. For example, the third electronic device 104 can be implemented as a bracket for mounting the first electronic device 101 and the second electronic device 102. For example, the third electronic device 104 can transmit power to the first electronic device 101 and the second electronic device 102 (wirelessly or wiredly) when the first electronic device 101 and the second electronic device 102 are mounted thereon. In other words, the third electronic device 104 can charge the first electronic device 101 and the second electronic device 102.

[0033] According to an embodiment, the third electronic device 104 can identify whether the first electronic device 101 and the second electronic device 102 are installed. For example, when the first electronic device 101 and the second electronic device 102 contact a charging terminal included in the third electronic device 104, the third electronic device 104 can determine that the first electronic device 101 and the second electronic device 102 are installed.

[0034] According to an embodiment, with the first electronic device 101 and the second electronic device 102 installed, the third electronic device 104 can send a notification signal indicating whether a cover (e.g., the lid of the third electronic device 104) is open or closed. For example, when the cover is closed or open, the third electronic device 104 can send a notification signal to the first electronic device 101 and / or the second electronic device 102. For example, the notification signal may be a signal indicating the open / closed state of the cover. For example, the third electronic device 104 can identify the closed state (or open state) of the cover by detecting the magnetic force of a magnet included in the cover via a Hall sensor. The third electronic device 104 can identify the closed state (or open state) of the cover by detecting that the illuminance decreases to a predetermined level when the cover is closed using an illuminance sensor. For example, when the cover is in the closed state, the first electronic device 101 and the second electronic device 102 installed on the third electronic device 104 can be located in an enclosed space.

[0035] According to an embodiment, when an enclosed space is formed, and the first electronic device 101 and the second electronic device 102 are mounted on the third electronic device 104, the first electronic device 101 and the second electronic device 102 can identify whether the performance of the speaker and microphone included in each of the first electronic device 101 and the second electronic device 102 is normal. The first electronic device 101 and the second electronic device 102 can identify the cause of performance degradation of the speaker and microphone included in each of the first electronic device 101 and the second electronic device 102. The operation of the first electronic device 101 and the second electronic device 102 is described below. Figure 2 To describe in more detail.

[0036] According to an embodiment, the fourth electronic device 108 can be implemented as a computing device (e.g., a smartphone or personal computer (PC)) capable of performing communication functions. For example, the fourth electronic device 108 can send / receive data to / from the first electronic device 101, the second electronic device 102, and the third electronic device 104. For example, the fourth electronic device 108 can send commands to the first electronic device 101 and the second electronic device 102 for performing specific functions. For example, the fourth electronic device 108 can send commands to the first electronic device 101 and the second electronic device 102 for controlling operations to identify whether the performance of the microphone and speaker included in each of the first electronic device 101 and the second electronic device 102 is normal. The fourth electronic device 108 can receive information indicating the status of the first electronic device 101 and the second electronic device 102 (e.g., the status of the speaker and microphone).

[0037] Figure 2 This is a block diagram illustrating an example electronic system according to various embodiments.

[0038] Reference Figure 2 The first electronic device 101 may include a first processor (e.g., which includes processing circuitry) 120, a first memory 125, a first speaker 130, a first microphone 140, and a first communication module (e.g., which includes communication circuitry) 145.

[0039] According to an embodiment, the first processor 120 may include various processing circuits and control the overall operation of the first electronic device 101. The first processor 120 can control the electronic device 101 to send / receive data to / from the second electronic device 102, the third electronic device 104, and the fourth electronic device 108 via the first communication module 145. For example, the first communication module 145 may include various communication circuits and support wireless communication technologies (e.g., Bluetooth communication technology).

[0040] According to an embodiment, the first processor 120 can receive a notification signal NI from the third electronic device 104 indicating whether the cover of the third electronic device 104 is in a closed state (or an open state). When the cover of the third electronic device 104 is in a closed state, the first electronic device 101 mounted on the third electronic device 104 can be located in an enclosed space.

[0041] According to an embodiment, when an enclosed space is formed, with the first electronic device 101 mounted on the third electronic device 104, the first processor 120 can output a first signal S1 with a predetermined frequency via the first speaker 130 in response to a trigger signal. For example, the trigger signal may be a signal used to initiate operation by the first electronic device 101 to identify whether the performance of the first speaker 130 and the first microphone 140 is normal. The trigger signal may be generated by the first processor 120 itself, or may be received from the second electronic device 102, the third electronic device 104, or the fourth electronic device 108. For example, the first sound S1 may be a sound having frequencies in several frequency bands having audible frequencies. For example, the first sound S1 may include various noises. For example, the first sound S1 may include at least one of pink noise, brown noise, or white noise.

[0042] According to an embodiment, the first processor 120 may output the first sound S1 from the first speaker 130 before the second sound S2 is output from the second speaker 160, based on a trigger signal. The first processor 120 may also output the first sound S1 from the first speaker 130 after the second sound S2 is output from the second speaker 160, based on a trigger signal. In other words, the first processor 120 may control the first speaker 130 based on a trigger signal to allow the first sound S1 and the second sound S2 to not be output simultaneously. For example, the trigger signal may include information about the timing of the first processor 120 outputting the first sound S1 from the first speaker 130.

[0043] According to an embodiment, the first processor 120 can obtain a third sound S11 through the first microphone 140. The third sound S11 is the reflection of the first sound S1 in the enclosed space of the third electronic device 104 (e.g., a bracket). For example, the third sound S11 can be the sound result of the first sound S1 output by the first speaker 130 being reflected in the enclosed space of the third electronic device 104 and obtained through the first microphone 140.

[0044] According to an embodiment, the first processor 120 can obtain a fourth sound S21 via a first microphone 140. The fourth sound S21 is the reflection of a second sound S2 output from a second electronic device 102 (or a second speaker 160) mounted on a third electronic device 104 (e.g., a bracket) within the enclosed space of the third electronic device 104. For example, the second sound S2 can be a sound having frequencies in several frequency bands including audible frequencies. For example, the second sound S2 can include various noises. For example, the second sound S2 can include at least one of pink noise, brown noise, or white noise. For example, the second sound S2 can be implemented as the same sound as the first sound S1 or a different sound from the first sound S1. For example, the fourth sound S21 can be the sound result of the second sound S2 output by the second speaker 160 of the second electronic device 102 being reflected within the enclosed space of the third electronic device 104 and obtained via the first microphone 140.

[0045] According to an embodiment, the first processor 120 can sequentially acquire a third sound S11 and a fourth sound S21 via a first microphone 140. The first processor 120 can acquire reference data RD from a first memory 125 to analyze the third sound S11 and the fourth sound S21. For example, the reference data RD may be data acquired when the speakers 130 and 160 and the microphones 140 and 170 included in the first electronic device 101 and the second electronic device 102 are functioning normally. For example, the reference data RD may include information about multiple reference signals based on combinations of speakers 130 and 160 and microphones 140 and 170 of the first electronic device 101 and the second electronic device 102.

[0046] According to an embodiment, the first processor 120 can compare a first reference signal with a signal corresponding to the third sound S11. For example, the first reference signal may be a reference signal based on a combination of the first speaker 130 and the first microphone 140. The first processor 120 can compare the first reference signal and the signal corresponding to the third sound S11 in at least one specific frequency band, and identify whether the performance of the first speaker 130 and / or the first microphone 140 has degraded based on the comparison result. The first processor 120 can identify whether the performance of the first speaker 130 and / or the first microphone 140 has degraded based on the comparison result.

[0047] For example, refer to Figure 3The first processor 120 can compare the first reference signal 310 with the first signal 320 corresponding to the third sound S11. The first processor 120 can obtain a first difference D1 between the first signal 320 and the first reference signal 310 in the first frequency band H1. The first processor 120 can compare the first difference D1 with a first threshold, and when the first difference D1 is greater than the first threshold, determine that the performance of at least one of the first speaker 130 and the first microphone 140 has degraded. The first processor 120 can determine that the performance of at least one of the first speaker 130 and the first microphone 140 has degraded due to foreign matter (e.g., water) corresponding to the first frequency band H1. The first threshold can be a reference value used to determine whether the performance of the first speaker 130 and the first microphone 140 is normal in the first frequency band H1. For example, the first threshold can be a constant or a ratio relative to a reference value. For example, when the amplitude of a signal at a specific frequency differs from a reference value by a specific ratio or more, the first processor 120 can determine that the performance is abnormal.

[0048] For example, the first processor 120 can obtain a second difference D2 between the first signal 320 and the first reference signal 310 in the second frequency band H2. The first processor 120 can compare the second difference D2 with a second threshold, and when the second difference D2 is greater than the second threshold, determine that the performance of at least one of the first speaker 130 and the first microphone 140 has degraded. The first processor 120 can determine that the performance of at least one of the first speaker 130 and the first microphone 140 has degraded due to a foreign object (e.g., a stone) corresponding to the second frequency band H2. For example, the second threshold can be a reference value used to determine whether the performance of the first speaker 130 and the first microphone 140 is normal in the second frequency band H2. For example, the second threshold can be a constant or a ratio relative to a reference value. For example, when the amplitude of a signal at a specific frequency differs from a reference value by a specific ratio or more, the second processor 150 can determine that the performance is abnormal.

[0049] For example, when the first difference D1 is not greater than the first threshold and the second difference D2 is not greater than the second threshold, the first processor 120 can determine that the performance of the first speaker 130 and the first microphone 140 is normal.

[0050] According to an embodiment, the first processor 120 can compare a second reference signal with a signal corresponding to the fourth sound S21. For example, the second reference signal may be a reference signal based on a combination of the second speaker 160 and the first microphone 140. The first processor 120 can compare the second reference signal with the signal corresponding to the fourth sound S21 in at least one specific frequency band and identify whether the performance of the second speaker 160 and / or the first microphone 140 has degraded based on the comparison result. The first processor 120 can identify the cause of the performance degradation of the second speaker 160 and / or the first microphone 140 based on the comparison result. For example, it can be combined with the above. Figure 3 The method described is performed in the same manner to compare the second reference signal and the signal corresponding to the fourth sound S21 and to identify whether the performance of the second speaker 160 and / or the first microphone 140 has degraded.

[0051] According to an embodiment, when a user first uses the first electronic device 101, with the third electronic device 104 (e.g., a bracket) in a closed state, the first processor 120 can obtain data waveforms (or data related to the waveforms corresponding to the sounds) via the first microphone 140 corresponding to the sounds output from each of the first speaker 130 and the second speaker 160. The first processor 120 can determine a first reference signal and a second reference signal based on the obtained data waveforms. The first processor 120 can store the first reference signal and the second reference signal in a memory 125.

[0052] According to an embodiment, the first processor 120 can obtain first result information RI1 indicating the performance of the first speaker 130, the second speaker 160, and the first microphone 140. The first processor 120 can send the first result information RI1 to the second electronic device 102. The first processor 120 can receive second result information RI2 or final result information RI from the second electronic device 102. For example, the first result information RI1 can be result information obtained by the first electronic device 101, and the second result information RI2 can be result information obtained by the second electronic device 102. For example, when the first processor 120 receives the second result information RI2, the first processor 120 can obtain the final result information RI based on the first result information RI1 and the second result information RI2.

[0053] According to an embodiment, the first processor 120 can output voice corresponding to the final result information RI through the first speaker 130. For example, when a pressure sensor (not shown) identifies that a user is wearing the first electronic device 101, the first processor 120 can output voice corresponding to the final result information RI through the first speaker 130.

[0054] According to an embodiment, the first speaker 130 may include at least one vibrating component (e.g., which includes circuitry). For example, when the first speaker 130 includes multiple vibrating components, each of the multiple vibrating components may output sound in a different frequency band. The first processor 120 may output a first sound S1 through at least one of the multiple vibrating components. In this case, the first processor 120 may obtain first result information indicative of the performance of the first microphone 140, the second speaker 160, and at least one vibrating component included in the first speaker 130 by the method described above.

[0055] although Figure 2 The first electronic device 101 is shown to include only the first microphone 140, but this is only for ease of description, and the spirit of this disclosure is not limited thereto. For example, the first electronic device 101 may include multiple microphones. In this case, the first processor 120 can obtain first result information indicating the performance of the first speaker 130, the second speaker 160, and the multiple microphones by the method described above.

[0056] According to an embodiment, the second electronic device 102 may include a second processor (e.g., which includes processing circuitry) 150, a second memory 155, a second speaker 160, a second microphone 170, and a second communication module (e.g., which includes communication circuitry) 175.

[0057] According to an embodiment, the second processor 150 may include various processing circuits and control the overall operation of the second electronic device 102. The second processor 150 can control the second electronic device 102 to send / receive data to / from the first electronic device 101, the third electronic device 104, and the fourth electronic device 108 via the second communication module 175. For example, the second communication module 175 may include various communication circuits and support wireless communication technologies (e.g., Bluetooth communication technology).

[0058] According to an embodiment, the second processor 150 can receive a notification signal NI from the third electronic device 104 indicating whether the cover of the third electronic device 104 is in a closed (or open) state. When the cover of the third electronic device 104 is in a closed state, the second electronic device 102 mounted on the third electronic device 104 can be located in an enclosed space.

[0059] According to an embodiment, when an enclosed space is formed, with the second electronic device 102 mounted on the third electronic device 104, the second processor 150 can output a second signal S2 with a predetermined frequency via the second speaker 160 in response to a trigger signal. For example, the trigger signal may be a signal used to initiate operation by the second electronic device 102 to identify whether the performance of the second speaker 160 and the second microphone 170 is normal. The trigger signal may be generated by the second processor 150 itself, or it may be received from the first electronic device 101, the third electronic device 104, or the fourth electronic device 108.

[0060] According to an embodiment, the second processor 150 may output a second sound S2 from the second speaker 160 after the first sound S1 is output from the first speaker 130, based on a trigger signal. The second processor 150 may also output the second sound S2 from the second speaker 160 before the first sound S1 is output from the first speaker 130, based on a trigger signal. In other words, the second processor 150 may control the second speaker 160 based on a trigger signal to allow the first sound S1 and the second sound S2 to not be output simultaneously. For example, the trigger signal may include information about the timing of the second processor 150 outputting the second sound S2 from the second speaker 160.

[0061] According to an embodiment, the second processor 150 can obtain a fifth sound S22 via a second microphone 170. The fifth sound S22 is the reflection of the second sound S2 in the enclosed space of the third electronic device 104 (e.g., a bracket). For example, the fifth sound S22 can be the sound result of the second sound S2 output by the second speaker 160 being reflected in the enclosed space of the third electronic device 104 and obtained through the second microphone 170.

[0062] According to an embodiment, the second processor 150 can obtain a sixth sound S12 via a second microphone 170. The sixth sound S12 is the reflection of a first sound S1 output from a first electronic device 102 (or a first speaker 130) mounted on a third electronic device 104 (e.g., a bracket) within the enclosed space of the third electronic device 104. For example, the sixth sound S12 can be the sound result of the first sound S1 output through the first speaker 130 being reflected within the enclosed space of the third electronic device 104 and obtained via the second microphone 170.

[0063] According to an embodiment, the second processor 150 can sequentially acquire the fifth sound S22 and the sixth sound S12 via the second microphone 170. The second processor 150 can obtain reference data RD from the second memory 155 to analyze the fifth sound S22 and the sixth sound S12. For example, the reference data RD may include information about multiple reference signals based on the combination of speakers 130 and 160 and microphones 140 and 170 of the first electronic device 101 and the second electronic device 102.

[0064] According to an embodiment, the second processor 150 can compare a third reference signal with a signal corresponding to the fifth sound S22. For example, the third reference signal may be a reference signal based on a combination of the second speaker 160 and the second microphone 170. The second processor 150 can compare the third reference signal with the signal corresponding to the fifth sound S22 in at least one specific frequency band and identify, based on the comparison result, whether the performance of the second speaker 160 and / or the second microphone 170 has degraded. The second processor 150 can identify the cause of the performance degradation of the second speaker 160 and / or the second microphone 170 based on the comparison result. For example, it can be combined with the above... Figure 3 The method for comparing the third reference signal and the signal corresponding to the fifth sound S22 and identifying whether the performance of the second speaker 160 and / or the second microphone 170 has degraded is performed in the same or similar manner as described.

[0065] According to an embodiment, the second processor 150 can compare a fourth reference signal with a signal corresponding to the sixth sound S12. For example, the fourth reference signal may be a reference signal based on a combination of the first speaker 130 and the second microphone 170. The second processor 150 can compare the fourth reference signal with the signal corresponding to the sixth sound S12 in at least one specific frequency band and identify, based on the comparison result, whether the performance of the first speaker 130 and / or the second microphone 170 has degraded. The second processor 150 can identify the cause of the performance degradation of the first speaker 130 and / or the second microphone 170 based on the comparison result. For example, it can be combined with the above... Figure 3 The method described is performed in the same manner to compare the fourth reference signal and the signal corresponding to the sixth sound S12 and to identify whether the performance of the first speaker 130 and / or the second microphone 170 has degraded.

[0066] According to an embodiment, when a user first uses the second electronic device 102, with the third electronic device 104 (e.g., a bracket) in a closed state, the second processor 150 can obtain data waveforms corresponding to the sounds output from each of the first speaker 130 and the second speaker 160 via the first microphone 170. The second processor 150 can determine a third reference signal and a fourth reference signal based on the obtained data waveforms. The second processor 150 can store the third reference signal and the fourth reference signal in a memory 155.

[0067] According to an embodiment, the second processor 150 can obtain second result information RI2, which indicates the performance of the first speaker 130, the second speaker 160, and the second microphone 170. The second processor 150 can send the second result information RI2 to the first electronic device 101. The second processor 150 can receive first result information RI1 or final result information RI from the first electronic device 101. For example, when the second processor 150 receives the first result information RI1, the second processor 150 can obtain the final result information RI based on the first result information RI1 and the second result information RI2.

[0068] For example, refer to Figure 4 The second processor 150 can obtain the result values ​​between the first speaker 130, the second speaker 160, the first microphone 140, and the second microphone 170 based on the first result information RI1 and the second result information RI2. The second processor 150 can obtain the final result information RI by comparing the result values ​​with table 400 stored in the second memory 155. For example, when the first result value 410 is obtained, the second processor 150 can determine that the performance of the first speaker 130 is abnormal. When the second result value 420 is obtained, the second processor 150 can determine that the performance of the second speaker 160 and the second microphone 170 is abnormal. The first processor 120 can also obtain the final result information RI by the same or similar method described above.

[0069] According to an embodiment, the second processor 150 can output voice corresponding to the final result information RI through the second speaker 160. For example, when a pressure sensor (not shown) identifies that a user is wearing the second electronic device 102, the second processor 150 can output voice corresponding to the final result information RI through the second speaker 160. For example, when a first result value 410 is obtained, the second processor 150 can output voice through the second speaker 160, saying "The first speaker is malfunctioning".

[0070] According to an embodiment, the second speaker 160 may include a plurality of vibrating components, each comprising various circuits. For example, each of the plurality of vibrating components may output sound in a different frequency band. The second processor 150 may output a second sound S2 through at least some of the plurality of vibrating components.

[0071] although Figure 2 The second electronic device 102 is shown to include only the second microphone 170, but this is only for ease of description, and the spirit of this disclosure is not limited thereto. For example, the second electronic device 102 may include multiple microphones. In this case, the second processor 150 can obtain second result information indicative of the performance of the first speaker 130, the second speaker 160, and the multiple microphones by the method described above.

[0072] According to an embodiment, the third electronic device 104 may include a third processor (e.g., which includes processing circuitry) 180, a third memory 185, a sensor 190, and a third communication module (e.g., which includes communication circuitry) 195.

[0073] According to an embodiment, the third processor 180 may include various processing circuits and control the overall operation of the third electronic device 104. The third processor 180 can control the third electronic device 104 to send / receive data to / from the first electronic device 101, the second electronic device 102, and the fourth electronic device 108 via the third communication module 195. For example, the third communication module 195 may include various communication circuits and support contact-type communication interfaces or wireless communication technologies (e.g., Bluetooth communication technology).

[0074] According to an embodiment, the third processor 180 can send a notification signal NI to the first electronic device 101 and / or the second electronic device 102 via the third communication module 195, indicating whether a cover (e.g., the lid of the third electronic device 104) is open or closed when the first electronic device 101 and the second electronic device 102 are installed. For example, the notification signal NI may refer to a signal indicating the open / closed state of the cover. For example, the third electronic device 104 can identify the closed (or open) state of the cover by detecting the magnetic force of a magnet included in the cover via a sensor 190 (e.g., a Hall sensor).

[0075] According to an embodiment, the third processor 180 can obtain final result information RI from the first electronic device 101 or the second electronic device 102 via the third communication module 195. The third processor 180 can obtain first result information RI1 and second result information RI2 from the first electronic device 101 or the second electronic device 102 via the third communication module 195. The third processor 180 can obtain the final result information RI based on the first result information RI1 and the second result information RI2. The third processor 180 can provide the final result information RI to a visual and / or tactile mechanism via an output device (not shown). The third processor 180 can store the final result information RI in a third memory 185.

[0076] although Figure 2 The illustration shows that each of the first electronic device 101 and the second electronic device 102 includes a microphone and a speaker, but the spirit of this disclosure is not limited thereto. In other words, although each of the first electronic device 101 and the second electronic device 102 includes multiple microphones and / or speakers, the first electronic device 101 and the second electronic device 102 can identify whether the microphones and / or speakers are functioning properly by means of the same or similar methods as described above.

[0077] For ease of description, as a non-limiting example, the first electronic device 101 and the second electronic device 102 are described as a first earphone and a second earphone, respectively. As a non-limiting example, the third electronic device 104 is also described as a bracket, and the fourth electronic device 108 is an external terminal. However, this disclosure is not limited to these.

[0078] Figure 5 This is a flowchart illustrating example operations of an electronic device identifying whether the performance of a speaker and microphone is normal, according to various embodiments.

[0079] Reference Figure 5 According to an embodiment, in operation 501, the first earphone 101 can identify whether the holder 104 is in a closed state. For example, the first earphone 101 can identify whether the holder 104 is in a closed state based on a notification signal received from the holder 104. The first earphone 101 can also identify whether it is mounted on the holder 104. For example, when the first earphone 101 contacts a charging terminal included in the holder 104, the first earphone 101 can be determined to be mounted on the holder 104.

[0080] According to an embodiment, when the tray 104 is in the closed state, the first earphone 101 can perform an operation to identify whether the earphone performance is normal. For example, whenever the tray 104 is closed, the first earphone 101 can automatically perform the operation to identify whether the earphone performance is normal. When the tray 104 is closed a predetermined number of times, the first earphone 101 can perform the operation to identify whether the earphone performance is normal. According to an embodiment, when a trigger signal requesting identification of earphone performance is detected, the first earphone 101 can perform the operation to identify whether the earphone performance is normal. For example, the trigger signal can be generated in response to user input requesting identification of earphone performance. For example, the first earphone 101 can receive the trigger signal from the external terminal 108. The first earphone 101 can receive the trigger signal from the tray 104.

[0081] According to an embodiment, in operation 503, with the bracket 104 in the closed state, the first earphone 101 can output a first sound with a predetermined frequency through the first speaker 130. For example, the predetermined frequency may be a frequency in several frequency bands that include audible frequencies.

[0082] According to an embodiment, in operation 505, the first earphone 101 can obtain a third sound corresponding to the first sound through the first microphone 140. For example, the third sound may be the sound result when the first sound is reflected in the enclosed space formed when the bracket 104 is closed and enters the first microphone 140.

[0083] According to an embodiment, in operation 507, the first earphone 101 can obtain a fourth sound corresponding to the second sound output from the external second earphone 102 via the first microphone 140. For example, the fourth sound may be the result of the second sound being reflected in the enclosed space formed when the bracket 104 is closed and entering the first microphone 140.

[0084] According to an embodiment, in operation 509, the first earphone 101 can identify whether the performance of the first speaker 130 and the first microphone 140 included in the first earphone 101 is normal based on the third and fourth sounds.

[0085] According to an embodiment, in operation 511, the first earphone 101 can obtain performance information about the second speaker 160 and the second microphone 170 included in the external second earphone 102, which is recognized by the external second earphone.

[0086] According to an embodiment, in operation 513, the first earphone 101 can identify the performance of the first earphone 101 and the second earphone 102. For example, the first earphone 101 can identify whether the performance of the first speaker 130, the first microphone 140, the second speaker 160, and the fourth microphone 170 is normal.

[0087] Figure 6 This is a flowchart illustrating an example method, according to various embodiments, for comparing a reference signal with a signal corresponding to sound obtained by an electronic device.

[0088] Reference Figure 6 According to an embodiment, in operation 601, the first earphone 101 can obtain a third sound and a fourth sound through the first microphone 140. For example, when the bracket 104 is identified as being in an off state, the first earphone 101 can obtain the third sound and the fourth sound in sequence.

[0089] According to an embodiment, in operation 603, the first earphone 101 can compare a first reference signal and a first signal corresponding to a third sound in at least one frequency band.

[0090] According to an embodiment, in operation 605, the first earphone 101 can compare the second reference signal and the second signal corresponding to the fourth sound in at least one frequency band. For example, each frequency band can be determined to determine whether a specific foreign object is present. According to an embodiment, operation 603 can be performed before the third and fourth sounds are obtained. After the fourth sound is obtained, operation 605 can be performed. According to an embodiment, after the third and fourth sounds are obtained, operations 603 and 605 can be performed sequentially.

[0091] According to an embodiment, in operation 607, the first earphone 101 can identify whether the performance of the first speaker 130 and the first microphone 140 included in the first earphone 101 is normal based on the comparison result. However, in order for the first earphone 101 to accurately determine whether the performance is normal, the first earphone 101 may need information about the performance of the second speaker 160 and the second microphone 170 obtained from an external second earphone 102. For this purpose, the first earphone can obtain information about the performance of the second speaker 160 and the second microphone 170 from the second earphone 102. Further considering the information about the second speaker 160 and the second microphone 170, the first earphone can identify whether the performance of the first speaker 130, the first microphone 140, the second speaker 160, and the second microphone 170 is normal.

[0092] Figure 7 This is a flowchart illustrating example operations of an electronic device identifying whether the performance of a speaker and microphone is normal, according to various embodiments.

[0093] Reference Figure 7According to an embodiment, in operation 701, the first earphone 101 can compare a reference signal (e.g., a first reference signal or a second reference signal) and a signal corresponding to a sound (e.g., a third sound or a fourth sound) (e.g., a first signal or a second signal) in a first frequency band to identify the presence of a first foreign object. For example, the reference signal may be a signal obtained when the user first uses the first earphone 101. The reference signal may be a signal pre-stored during the manufacturing process of the first earphone 101.

[0094] For ease of description, the description focuses primarily on the operation of the first earphone 101 comparing the first reference signal and the first signal corresponding to the third sound. However, the first earphone 101 can perform the operation of comparing the second reference signal and the second signal corresponding to the fourth sound using the same or similar method as described above.

[0095] According to an embodiment, in operation 703, the first earphone 101 can identify the difference between a reference data value and a data value of a first signal corresponding to the sound in a first frequency band.

[0096] According to an embodiment, the first earphone 101 can compare the difference between the data value of the first signal and the reference data value with a predetermined threshold. In operation 705, the first earphone 101 can identify whether the difference between the data value of the first signal and the reference data value exceeds the threshold.

[0097] According to an embodiment, when the difference between the data value of the first signal and the reference data value exceeds a threshold (Yes in operation 705), in operation 707, the first earphone 101 can identify a performance abnormality of at least one of the first speaker 130, the first microphone 140 and the second speaker 160.

[0098] According to an embodiment, when the difference between the data value of the first signal and the reference data value does not exceed a threshold (No in operation 705), in operation 709, the first earphone 101 can identify that at least one of the first speaker 130, the first microphone 140 and the second speaker 160 is performing normally.

[0099] According to an embodiment, the first earphone 101 can compare a first reference signal and a first signal in a second frequency band corresponding to the second foreign object to identify whether a second foreign object different from the first foreign object exists. The first earphone 101 can identify whether the performance of at least one of the first speaker 130, the first microphone 140, and the second speaker 160 is normal based on the comparison result.

[0100] The second earphone 102 can also compare the reference signal and the signal corresponding to the sound using the method described above.

[0101] Figure 8This is a flowchart illustrating example operations of an electronic device providing information about a foreign object according to various embodiments. Figure 9A and Figure 9B This is a table illustrating example operations of an electronic device providing information about a foreign object according to various embodiments.

[0102] Reference Figure 8 According to an embodiment, in operation 801, the first earphone 101 can compare a reference signal (e.g., a first reference signal or a second reference signal) with a signal (e.g., a first signal or a second signal) corresponding to a sound (e.g., a third sound or a fourth sound) in each frequency band corresponding to a predetermined foreign object.

[0103] For ease of description, the description focuses primarily on the operation of the first earphone 101 comparing the first reference signal and the first signal corresponding to the third sound. However, the first earphone 101 can perform the operation of comparing the second reference signal and the second signal corresponding to the fourth sound using the same or similar method as described above.

[0104] According to an embodiment, in operation 803, the first earphone 101 can identify the type of foreign object based on the comparison result.

[0105] Reference Figure 9A The first earpiece 101 can determine a frequency band for identifying the presence of a specific foreign object. For example, the frequency band can be determined based on the type of foreign object. Reference data can be specified to determine the presence of a foreign object in each frequency band. A threshold can be specified to determine the presence of a foreign object in each frequency band. For example, to determine the presence of a foreign object "water," the first earpiece 101 can compare a first signal with a first reference signal in a first frequency band (e.g., 15000Hz). In this case, the reference data value of the first reference signal can be 60dB. In other words, the first earpiece 101 can identify whether the difference between the reference data value and the value of the first signal is 2dB at 15000Hz, and based on the identification result, determine whether the performance of the first earpiece 101 or the second earpiece 102 is normal. For example, to determine the presence of a foreign object "stone," the first earpiece 101 can compare the first signal with the first reference signal in a second frequency band (e.g., 12000Hz). In this case, the reference data value of the first reference signal can be 50dB. In other words, the first earphone 101 can identify whether the difference between the reference data value and the value of the first signal is 5dB at 12000Hz, and determine whether the performance of the first earphone 101 or the second earphone 102 is normal based on the identification result.

[0106] Reference Figure 9BThe first earpiece 101 can identify foreign substances that can be mixed together. For example, the foreign substances "water" and "starch" can be mixed. However, when a reference signal is compared with a first signal in the frequency band corresponding to "water" (e.g., 15000 Hz) and the frequency band corresponding to "starch" (e.g., 375 Hz), the first earpiece 101 can identify the foreign substance mixture of "water" and "starch" as "water".

[0107] According to an embodiment, when a foreign object is identified as a miscible material (e.g., "water" or "starch"), the first earphone 101 can identify whether the foreign object is "water" or "starch" or a mixture of "water" or another foreign object (e.g., starch).

[0108] According to an embodiment, when a foreign object is identified as "water" or "starch," the first earpiece 101 can compare a reference signal with a first signal in three additional frequency bands. For example, when a threshold is exceeded only in the "375Hz" frequency band, the first earpiece 101 can determine that the foreign object is "starch." When the threshold is exceeded in the "3234Hz" frequency band, the "9890Hz" frequency band, and the "375Hz" frequency band, the first earpiece 101 can determine that the foreign object is "water." In other cases, the first earpiece 101 can determine that the foreign object is a mixture of "water" and "starch."

[0109] According to an embodiment, in operation 805, the first earphone 101 can provide information about the type of foreign object. For example, the first earphone 101 can provide information about the type of foreign object to the bracket 104 and / or the external terminal 108. When the first earphone 101 is identified as being worn by a user, the first earphone 101 can output the information about the type of foreign object as sound through the first speaker 130.

[0110] The second earphone 102 can also provide information about the type of foreign object using the method described above.

[0111] Figure 10 This is a flowchart illustrating example operations for identifying whether the performance of a speaker and microphone is normal based on signal attenuation and delay caused by electronic devices, according to various embodiments. Figure 11 This is a graph illustrating example operations for identifying whether the performance of a speaker and microphone is normal based on signal attenuation and delay caused by electronic devices according to various embodiments.

[0112] Reference Figure 10 According to an embodiment, in operation 1001, the first earphone 101 can compare a reference signal (e.g., a first reference signal or a second reference signal) with a signal (e.g., a first signal or a second signal) corresponding to a sound (e.g., a third sound or a fourth sound).

[0113] According to an embodiment, in operation 1003, when two signals are identical or similar in form, the first earphone 101 can identify whether the signal corresponding to the sound is attenuated and / or delayed based on a reference signal.

[0114] Reference Figure 11 According to an embodiment, the first earphone 101 can compare the reference signal 1110 with the signal 1120 or 1130 corresponding to the sound. For example, the first earphone 101 can compare the reference signal 1110 with the signal 1120 and determine that the signal 1120 has been delayed by time "t". The first earphone 101 can compare the reference signal 1110 with the signal 1130 and determine that the signal 1130 has been attenuated by intensity "h".

[0115] According to an embodiment, in operation 1005, the first earphone 101 can identify whether the earphone performance is normal based on signal attenuation and / or delay. For example, when signal attenuation and / or delay is detected, the first earphone 101 can determine that the earphone performance is abnormal. When the degree of signal attenuation and / or delay exceeds a predetermined threshold, the first earphone 101 can determine that the earphone (e.g., the first earphone 101 and / or the second earphone 102) is abnormal. When the degree of signal attenuation and / or delay is not greater than the predetermined threshold, the first earphone 101 can determine that the earphone (e.g., the first earphone 101 and / or the second earphone 102) is normal.

The second electronic device 102 can also obtain the third sound and the fourth sound. For example, operations 1205 and 1207 can be performed on the first electronic device 101 and the second electronic device 102 to sequentially output the first sound and the second sound, and obtain the third sound and the fourth sound.

[0120] According to an embodiment, in operation 1209, the second electronic device 102 can obtain information about the performance of the second electronic device 102 (e.g., the performance of the first speaker 130, the second speaker 160, and the second microphone 170) by analyzing the third and fourth sounds, and send the performance information about the second electronic device 102 to the first electronic device 101.

In operation 1211, the first electronic device 101 can determine final result information based on the information about its performance and the information about the performance of the second electronic device 102. For example, the final result information may include information about whether the performance of the first speaker 130, the first microphone 140, the second speaker 160, and the second microphone 170 is normal.

[0122] According to an embodiment, in operation 1213, the first electronic device 101 can send final result information about the performance of the first electronic device 101 and the second electronic device 102 to the bracket 104.

[0128] According to an embodiment, in operation 1253, terminal 108 may generate a trigger signal to begin identifying headphone performance upon recognizing user input requesting headphone performance identification. For example, when an application for managing wireless headphones is running, terminal 108 may display a running screen including an object for identifying headphone performance. Upon recognizing user input for the object, terminal 108 may generate a trigger signal. For example, the trigger signal may be a signal for initiating operation by which the first electronic device 101 identifies whether the headphone performance is normal.

As used herein, each of the phrases such as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C” may include any one or all possible combinations of the items enumerated together with the corresponding phrase among the plurality of phrases. As used herein, terms such as “first” and “second” or “first” and “second” may be used to simply distinguish the respective component from another component and do not limit the component in other respects (e.g., importance or order). It will be understood that, whether the terms “operably” or “communically” are used or not, if an element (e.g., a first element) is referred to as “combined with another element (e.g., a second element),” “combined to another element (e.g., a second element),” “connected to another element (e.g., a second element),” or “connected to another element (e.g., a second element)”, it means that the element can be directly (e.g., wiredly) connected to the other element, wirelessly connected to the other element, or connected to the other element via a third element.

[0196] As used in connection with various embodiments of this disclosure, the term "module" may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with other terms such as "logic," "logic block," "part," or "circuit." A module may be a single integrated component adapted to perform one or more functions, or the smallest unit or part of such a single integrated component. For example, according to embodiments, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0197] The various embodiments set forth herein can be implemented as software (e.g., program 1440) containing one or more instructions readable by a machine (e.g., electronic device 1401) stored in a storage medium (e.g., internal memory 1436 or external memory 1438). For example, under the control of a processor, the processor (e.g., processor 1420) of the machine (e.g., electronic device 1401) can invoke and execute at least one of the one or more instructions stored in the storage medium, with or without the use of one or more other components. This enables the machine to operate to perform at least one function according to the invoked at least one instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. Machine-readable storage media can be provided in the form of non-transitory storage media. The term "non-transitory" simply means that the storage medium is a tangible device and does not include signals (e.g., electromagnetic waves), but this term does not distinguish between data being stored semi-permanently in the storage medium and data being temporarily stored in the storage medium.

[0198] According to embodiments, methods according to various embodiments of this disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer.

If distributed online, at least a portion of the computer program product may be temporarily generated, or at least a portion of the computer program product may be stored at least temporarily in a machine-readable storage medium (such as the memory of a manufacturer's server, an app store's server, or a forwarding server).

[0199] According to various embodiments, each of the above-described components (e.g., a module or program) may include a single entity or multiple entities, and some of the multiple entities may be separately disposed in different components. According to various embodiments, one or more of the above-described components may be omitted, or one or more other components may be added. Optionally or additionally, multiple components (e.g., modules or programs) may be integrated into a single component. In this case, according to various embodiments, the integrated component may still perform the one or more functions of each of the multiple components in the same or similar manner as the corresponding component of the multiple components performed one or more functions before integration. According to various embodiments, the operations performed by a module, program, or other component may be performed sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be run in a different order or omitted, or one or more other operations may be added.

[0200] As is evident from the foregoing description, according to various embodiments, the electronic device can identify whether the speakers and microphones included in the electronic device are functioning properly without requiring the user to visit a service center.

[0201] While this disclosure has been shown and described with reference to various exemplary embodiments, it will be understood that these exemplary embodiments are intended to be illustrative rather than restrictive.
