Abstract

A method and electronic device for communicating audio signals with an audio input/output device is provided. The electronic device includes a USB type connection port, an audio processor configured to support conversion between a digital signal and an analog signal, and at least one processor configured to detect a connection of a peripheral device via the connection port, identify a type of the peripheral device, establish a first signal path for communicating the digital signal with the peripheral device through a first pin and/or a second pin included in the connection port based on whether the peripheral device supports a first mode, or establish a second signal path for communicating the analog signal with the peripheral device through the first pin and/or the second pin included in the connection port based on whether the peripheral device supports a second mode and whether a predetermined condition is satisfied.

Dependent claims

An electronic device comprising:

a universal serial bus (USB) type connection port;
a first audio processor configured to support analog to digital conversion and digital to analog conversion;
and
at least one processor connected to the first audio processor and the USB type connection port, the at least one processor configured to:
detect a connection of a peripheral device via the connection port,
identify a type of the peripheral device,
transmit digital audio signals to a speaker of the peripheral device and receive digital audio signals from a microphone of the peripheral device through a first signal path, in response to determining that the peripheral device supports only a first mode based on the type of the peripheral device,
transmit digital audio signals to the speaker of the peripheral device and receive digital audio signals from the microphone of the peripheral device through the first signal path, in response to determining that the peripheral device supports the first mode and a second mode based on the type of the peripheral device, and an application associated with RF (radio frequency) signal communication is terminated;
and
transmit analog audio signals to the speaker of the peripheral device and receive analog audio signals from the microphone of the peripheral device through a second signal path, in response to determining that the peripheral device additionally supports the first mode and the second mode based on the type of the peripheral device, and the application associated with RF signal communication is executed.
