Power supply device and method for searching audio output device using power supply device

A method for finding a position of an audio output device by using an electronic device, the method comprising:

• in a state where the electronic device connects a first communication with a first audio output device or is electrically connected with the first audio output device, operating in a connection standby mode or in an advertise mode by using a first wireless communication address of the first audio output device;
• receiving a signal for finding the first audio output device from an external electronic device, based on the first wireless communication address;
• and
• in response to the signal for finding the first audio output device being received, transmitting a signal for letting the first audio output device output a notification to the first audio output device through the first communication, or transmitting the signal to the first audio output device through the electrical connection.

An audio output device comprising:

• an audio processing circuit;
• a power management circuit;
• a wireless communication circuit configured to establish a communication connection by using a wireless communication address;
• and
• a control circuit electrically connected with the audio processing circuit, the power management circuit, and the wireless communication circuit,
• wherein the control circuit is configured to:
• establish a first communication connection with a power supply device by using the wireless communication circuit, or an electrical connection with the power supply device by using the power management circuit;
• receive, from the power supply device, a signal for finding at least one audio output device comprising the audio output device, the signal being received by the power supply device from an external electronic device;
• and
• in response to the signal for finding the at least one audio output device being received, control the audio processing circuit to output a notification.
