Electronic device including wireless earphone and cradle, and method of operating the same

An electronic device comprising:

• a wireless communication module for communication with an external device, the external device comprising a plurality of wireless earphones and a cradle on which the plurality of wireless earphones are disposed, the plurality of wireless earphones comprising a first wireless earphone and a second wireless earphone;
• a processor operatively coupled to the wireless communication module;
• and
• a memory operatively connected to the processor and storing a program for controlling an operation of the external device,
• wherein the memory comprises instructions, when executed, for controlling the processor to:
• check communication with the cradle and the plurality of wireless earphones;
• and
• control the cradle and the plurality of wireless earphones so that:
• when the first wireless earphone and the second wireless earphone are located inside the cradle, the cradle is controlled to transmit a first location finding alarm command to the first wireless earphone and the second wireless earphone causing the first wireless earphone and the second wireless earphone to output a location finding alarm at a first volume greater than or equal to a first threshold,
• when the first wireless earphone or the second wireless earphone are located outside the cradle, the cradle is controlled to determine whether at least one of the first wireless earphone or the second wireless earphone is worn on a user's ear,
• based on determining that the at least one of the first wireless earphone and the second wireless earphone is worn on the user's ear, the cradle is controlled to transmit a second location finding alarm command to the at least one of the first wireless earphone and the second wireless earphone, causing the at least one of the first wireless earphone and the second wireless earphone to output the location finding alarm at a second volume lower than the first volume,
• based on determining the first wireless earphone or the second wireless earphone are located outside the cradle and determining that neither the first wireless earphone nor the second wireless earphone is worn on the user's ear, the cradle is controlled to transmit a third location finding alarm command to the first wireless earphone and the second wireless earphone, causing the location finding alarm to be output at the first volume, and
• based on determining that one of the first wireless earphone and the second wireless earphone is located inside the cradle and other one of the first wireless earphone and the second wireless earphone is located outside the cradle and not worn on the user's ear, the cradle is controlled to transmit a fourth location finding alarm command to the other one of the first wireless earphone and the second wireless earphone located outside the cradle to cause the other one of the first wireless earphone and the second wireless earphone located outside the cradle to output the location finding alarm at the first volume, wake up the one of the first wireless earphone and the second wireless earphone located inside the cradle for outputting the location finding alarm at the first volume through the one located inside cradle.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a device cause the one or more processors to:
• check a communication connection with a cradle and a plurality of wireless earphones, the plurality of wireless earphones comprising a first wireless earphone and a second wireless earphone;
• and
• control the cradle and the plurality of wireless earphones so that:
• when the first wireless earphone and the second wireless earphone located inside the cradle, the cradle is controlled to transmit a first location finding alarm command to the first wireless earphone and the second wireless earphone causing the first wireless earphone and the second wireless earphone to output a location finding alarm at a first volume greater than or equal to a first threshold, and
• when at least one of the first wireless earphone or the second wireless earphone is located outside the cradle, the cradle is controlled to determine whether at least one of the first wireless earphone or the second wireless earphone is worn on a user's ear,
• based on determining that the at least one of the first wireless earphone or the second wireless earphone is worn on the user's ear, the cradle is controlled to transmit a second location finding alarm command to at least one of the first wireless earphone or the second wireless earphone, causing the at least one of the first wireless earphone or the second wireless earphone to output the location finding alarm at a second volume lower than the first volume,
• based on determining that the at least one of the first wireless earphone or the second wireless earphone is located outside the cradle and determining that neither the first wireless earphone nor the second wireless earphone is worn on the user's ear, the cradle is controlled to transmit a third location finding alarm command to the first wireless earphone and the second wireless earphone, causing the location finding alarm to be output at the first volume, and
• based on determining that one of the first wireless earphone and the second wireless earphone is located inside the cradle and other one of the first wireless earphone and the second wireless earphone is located outside the cradle and not worn on the user's ear, the cradle is controlled to transmit a fourth location finding alarm command to the other one of the first wireless earphone and the second wireless earphone located outside the cradle to cause the other one of the first wireless earphone and the second wireless earphone located outside the cradle to output the location finding alarm at the first volume, wake up the one of the first wireless earphone and the second wireless earphone located inside the cradle for outputting the location finding alarm at the first volume through the one located inside cradle,
• wherein the device comprises a wireless communication module, and wherein the wireless communication module is configured to communicate with an external terminal and the cradle and the plurality of wireless earphones.
