Document Type and Number:
WIPO Patent Application WO/2019/245328
Kind Code:
A1
Abstract:
An electronic device according to one embodiment comprises a first connector connectable to an external electronic device, a second connector connectable to an external audio plug, a wireless communication circuit and at least one processor, wherein, when the electronic device is connected to the external electronic device through the first connector, the at least one processor can receive a first digital audio signal from the external electronic device through the first connector, convert the first digital audio signal into a first analog audio signal, and output the first analog audio signal through the second connector and, when the electronic device is connected to the external electronic device through the wireless communication circuit, the at least one processor can receive a second digital audio signal from the external electronic device through the wireless communication circuit, convert the second digital audio signal into a second analog audio signal having a sound quality that is lower than the sound quality of the first analog audio signal, and output the second analog audio signal through the second connector.
