Positioning method using multiple devices and electronic device therefor

A wireless audio device comprising:

• a first wireless audio device including a first antenna, a first communication circuit connected to the first antenna, and a first processor connected to the first communication circuit, the first wireless audio device being configured to obtain first positioning information by receiving a positioning signal from an external electronic device using the first antenna;
• a second wireless audio device including a second antenna, a second communication circuit connected to the second antenna, and a second processor connected to the second communication circuit, the second wireless audio device being configured to obtain second positioning information by receiving the positioning signal using the second antenna;
• and
• a case configured to accommodate the first wireless audio device and the second wireless audio device at a fixed relative position,
• wherein a master device among the first wireless audio device and the second wireless audio device is configured to:
• identify an angle of arrival of the positioning signal based on the first positioning information, the second positioning information, and a specified antenna distance when the first wireless audio device and the second wireless audio device are accommodated in the case at the fixed relative position, and
• transmit a response signal including information of the identified angle of arrival to the external electronic device,
• wherein the specified antenna distance is based on a distance between the first antenna and the second antenna when the first wireless audio device and the second wireless audio device are accommodated in the case at the fixed relative position.
