Method of detecting external devices and electronic device for processing same

1. An electronic device comprising:

a memory; and

a processor electrically coupled to the memory,

wherein the processor executing instructions stored in the memory is configured to:

detect an insertion of earphones into a connector of the electronic device,

determine first polarity information based on location information of the electronic device in response to detecting the insertion of the earphones,

based on the first polarity information, set a sound path of the electronic device,

determine second polarity information detected from the inserted earphones,

determine whether a change of the sound path is required based on a comparison between the first polarity information and the second polarity information, and

change the sound path based on the second polarity information in response to determining that the change of the sound path is required.

2. The electronic device of claim 1 , wherein the first polarity information corresponds to polarity information stored in the memory before the insertion of the earphones is detected.

3. The electronic device of claim 1 , wherein the processor is configured to operate the inserted earphones through the sound path set based on the first polarity information in response to determining that the change of the sound path is not required.

4. The electronic device of claim 1 , wherein the processor is further configured to obtain identification information of the inserted earphones and to set a sound effect corresponding to the identification information,

wherein the sound effect comprises at least one of a high sound field effect, a low sound field effect, or equalizing effect.

5. The electronic device of claim 4 , wherein the processor is further configured to identify characteristics of the inserted earphones based on the identification information, and set the sound effect corresponding to the identified characteristics.

6. The electronic device of claim 1 , wherein the processor is further configured to receive, from the inserted earphones, identification information of the inserted earphones, or

obtain identification information by measuring a resistance value of the inserted earphones.

7. The electronic device of claim 1 , wherein the processor is further configured to determine that the change of the sound path is not required when the first polarity information and the second polarity information are identical.

8. The electronic device of claim 1 , wherein the processor is further configured to determine whether a change of the sound path is required based on a rule associated with the first polarity information and the second polarity information.

9. A method comprising:

detecting an insertion of earphones into a connector of an electronic device; and

setting a sound path of the electronic device based on predetermined polarity information in response to detecting the insertion of the earphones,

wherein the predetermined polarity information is determined based on polarity information corresponding to a location of the electronic device.

10. The method of claim 9 , wherein the predetermined polarity information is first polarity information stored in the electronic device before the detection of the insertion of the earphones.

11. The method of claim 10 , further comprising:

determining second polarity information detected from the inserted earphones;

determining whether a change of the sound path is required based on a comparison between the first polarity information and the second polarity information; and

changing the sound path based on the second polarity information in response to determining that the change of the sound path is required.

12. The method of claim 9 , wherein the predetermined polarity information is polarity information of non-microphone type earphones or microphone type earphones.

13. The method of claim 9 , further comprising:

obtaining identification information of the inserted earphones; and

setting a sound effect corresponding to the identification information,

wherein the sound effect comprises at least one of a high sound field effect, a low sound field effect, or equalizing effect.

14. The method of claim 13 , wherein the obtaining of the identification information comprising:

receiving, from the inserted earphones, the identification information of the inserted earphones; or

obtaining identification information by measuring a resistance value of the inserted earphones.

15. An electronic device comprising:

a memory; and

a processor electrically coupled to the memory,

wherein the processor executing instructions stored in the memory is configured to:

detect an insertion of earphones into a connector of the electronic device,

determine first polarity information based on location information of the electronic device in response to detecting the insertion of the earphones, and

display the first polarity information on a screen of the electronic device,

wherein the first polarity information is determined based on polarity information corresponding to a location of the electronic device.

16. The electronic device of claim 15 , wherein the processor is further configured to:

set a sound path of the electronic device based on the first polarity information,

determine second polarity information detected from the inserted earphones,

determine whether a change of the sound path is required based on a comparison between the first polarity information and the second polarity information, and

change the sound path based on the second polarity information in response to determining that the change of the sound path is required.

17. The electronic device of claim 16 , wherein the processor is further configured to obtain identification information of the inserted earphones, and set a sound effect corresponding to the identification information,

wherein the sound effect comprises at least one of a high sound field effect, a low sound field effect, or equalizing effect.
