Abstract

A wearable electronic device including a speaker and a microphone is configured to: generate a detection signal to detect whether a sound leakage occurs, receive, through the microphone, a feedback signal in which a signal obtained by outputting the detection signal into an ear canal of a user through the speaker is collected, calculate a difference value between the feedback signal and the detection signal, and correct a playback sound output by the wearable electronic device based on the difference value.

First claim

What is claimed is:

1. A method of operating a wearable electronic device comprising a speaker and a microphone, the method comprising:
generating a detection signal for detecting whether a sound leakage of the wearable electronic device occurs;
receiving, through the microphone, a feedback signal in which a signal obtained by outputting the detection signal into an ear canal through the speaker is collected;
calculating a difference value between the feedback signal and the detection signal; and
correcting a playback sound output by the wearable electronic device based on the difference value being within a permissible compensation range for the sound leakage; and
providing a notification to the user to adjust or replace the wearable electronic device based on the difference value exceeding the permissible compensation range for the sound leakage.

2. The method of claim 1 , wherein the correcting of the playback sound comprises:
correcting the playback sound based on whether the difference value corresponds to a permissible compensation range for the sound leakage.

3. The method of claim 2 , wherein the correcting of the playback sound comprises:
correcting the playback sound by compensating the playback sound for the difference value.

4. The method of claim 2 , wherein the providing of a notification to the user to adjust or replace the wearable electronic device comprises:
providing a notification for re-wearing the wearable electronic device or replacing an eartip.

5. The method of claim 4 , wherein the providing of the notification to the user to adjust or replace the wearable electronic device comprises:
providing the notification for replacing the eartip based on the difference value being greater than a permissible compensation value of the permissible compensation range and being less than or equal to a permissible sound leakage value of a permissible sound leakage range.

6. The method of claim 4 , wherein the providing of the notification to the user to adjust or replace the wearable electronic device comprises:
providing the notification for re-wearing the wearable electronic device based on the difference value being greater than a permissible sound leakage value of a permissible sound leakage range.

7. The method of claim 1 , wherein the correcting of the playback sound comprises:
correcting the playback sound based on whether the difference value satisfies a specific compensation condition.

8. The method of claim 7 , wherein the compensation condition comprises a condition wherein a magnitude of the difference value corresponding to a specific signal in the feedback signal is greater than a sum of magnitudes of difference values corresponding to other signals in the feedback signal.

9. The method of claim 8 , wherein, based on the difference value corresponding to the signal satisfying the compensation condition, the correcting of the playback sound comprises:
correcting the playback sound by adjusting a weight value corresponding to the signal in the playback sound.

10. The method of claim 1 , wherein the calculating of the difference value comprises:
calculating a first value obtained by converting a frequency of the detection signal;
calculating a second value obtained by converting a frequency of the feedback signal; and
calculating a difference value between the first value and the second value.

11. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the operations of claim 1 .

12. A wearable electronic device, comprising:
a sound generator comprising circuitry configured to generate a detection signal to detect whether a sound leakage occurs;
a speaker configured to output the detection signal into an ear canal;
a microphone configured to receive a signal output through the speaker; and
a processor configured to:
calculate a difference value between a feedback signal received through the microphone and the detection signal;
correct a playback sound output by the wearable electronic device based on the difference value being within a permissible compensation range for the sound leakage; and
provide a notification to the user to adjust or replace the wearable electronic device based on the difference value exceeding the permissible compensation range for the sound leakage.

13. The wearable electronic device of claim 12 , wherein the processor is configured to:
correct the playback sound by compensating the playback sound for the difference value based on whether the difference value corresponds to a permissible compensation range for the sound leakage.

14. The wearable electronic device of claim 13 , wherein the processor is configured to:
correct the playback sound by compensating the playback sound for the difference value.

15. The wearable electronic device of claim 13 , wherein the processor is configured to:
provide a notification to the user to adjust or replace the wearable electronic device by providing a notification to re-wear or replace an eartip based on the difference value being out of the permissible compensation range.

16. The wearable electronic device of claim 15 , wherein the processor is configured to:
provide the notification to the user to replace the eartip based on the difference value being greater than a permissible compensation value of the permissible compensation range and being less than or equal to a permissible sound leakage value of a permissible sound leakage range, or
provide the notification to the user to for-re-wearing the wearable electronic device based on the difference value being greater than a permissible sound leakage value of a permissible sound leakage range.

17. The wearable electronic device of claim 12 , wherein the processor is configured to:
correct the playback sound based on whether the difference value satisfies a specific compensation condition.

18. The wearable electronic device of claim 17 , wherein the compensation condition comprises a condition wherein a magnitude of the difference value corresponding to a signal in the feedback signal is greater than a sum of magnitudes of difference values corresponding to other signals in the feedback signal.

19. The wearable electronic device of claim 18 , wherein the processor is configured to:
correct the playback sound by adjusting a weight value corresponding to the signal in the playback sound.

20. The wearable electronic device of claim 12 , wherein the processor is configured to:
calculate a first value obtained by converting a frequency of the detection signal, calculate a second value obtained by converting a frequency of the feedback signal, and calculate a difference value between the first value and the second value.
