1. An electronic device comprising:
- a communication interface configured to wirelessly connect the electronic device to an external device, anda controller configured to;
in response to an input to turn on power of the electronic device, start a booting operation of the electronic device, and control the communication interface to transmit a wake-up signal to the external device in a standby state in which the external device transmits a request signal for requesting a connection with the electronic device, the wake-up signal instructing the external device in the standby state to supply a power to speaker components of the external device before a connection of the electronic device and the external device is completed;
in response to completion of the booting operation, transmit, a response signal for responding to the request signal, to the external device in the standby state to perform the connection with the external device; and
in response to completion of the connection with the external device, transmitting audio signal to the external device, the audio signal being used to be output by the speaker components of the external device.

Abstract
Provided is an electronic device. The electronic device includes a communicator that wirelessly connects the electronic device to an external device, and a controller that controls the communicator and transmits a wake-up signal to the external device, in response to an input to turn on the power of the electric device, to instruct the external device in a standby state to initiate an audio output preparing operation. The standby state corresponds to a state in which the external device attempts to establish a connection.
