A wireless audio device includes a communication module, a plurality of microphones comprising an internal microphone and an external microphone, and at least one processor configured to: receive a multi-recording conversion signal from an electronic device, enable at least one microphone of the internal microphone and the external microphone based on the multi-recording conversion signal, transmit a first audio signal generated based on a sound input through the enabled at least one microphone to the electronic device, detect a microphone control input, selectively mute or unmute the at least one microphone of the internal microphone and the external microphone based on the microphone control input, and transmit, to the electronic device, a second audio signal generated based on a microphone input acquired in a state where the at least one microphone of the internal microphone and the external microphone is selectively muted or unmuted based on the microphone control input.

Method and device for controlling microphone input/output by wireless audio device during multi-recording in electronic device

An electronic device includes a battery, a charging integrated circuit (IC) configured to control a charging state of the battery, a connector pin for receiving power from an external device, the connector pin including a first connector pin for receiving a high potential voltage from the external device and a second connector pin for receiving a low potential voltage from the external device, a touch sensor, and a controller. The controller receives power from the external device through the connector pin based on the detection of the external device being connected to the connector pin, charges the battery using a high potential voltage, detects a user input through the touch sensor while the battery is charged, and stops the charging of the battery and outputs a current corresponding to state information of the electronic device through the first connector pin based on the detection of the given user input.
