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.

First claim

What is claimed is:

1 . An electronic device comprising:
a communicator configured to wirelessly connect the electronic device to an external device, and a controller configured to control the communicator and transmit 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 corresponding to a state in which the external device attempts to establish a connection.

2 . The electronic device of claim 1 , wherein the controller is further configured to transmit the wake-up signal to the external device and initiate an operation of booting the electronic device in response to the input to turn on the power of the electric device.

3 . The electronic device of claim 1 , wherein the controller periodically receives connection request signals requesting a connection to the electronic device from the external device via the communicator while the external device is in the standby state.

4 . The electronic device of claim 3 , wherein the controller is further configured to transmit a connection success signal to the external device in response to the connection request signals from the external device when the electronic device is in a connectable state by completing an operation of booting.

5 . The electronic device of claim 4 , wherein the controller transmits audio data to the external device in response to the connection to the external device being established.

6 . An audio device comprising:
a communicator configured to wirelessly connect the audio device to an electronic device; and a controller configured to control the communicator and instruct the audio device in a standby state to initiate an audio output preparing operation of the audio device in response to reception of a wake-up signal, the standby state corresponding to a state in which the audio device attempts to establish a connection.

7 . The audio device of claim 6 , wherein the controller is further configured to periodically transmit connection request signals requesting a connection to the electronic device to the electronic device via the communicator while the audio device is in the standby state.

8 . The audio device of claim 7 , wherein the controller is further configured to output audio data received from the electronic device in response to a connection success signal being received in response to the connection request signals.

9 . The audio device of claim 7 , wherein the controller is further configured to display, on a display of the audio device, a message notifying that the audio device is turned on, in response to a connection success signal being received in response to the connection request signals.

10 . A method of controlling an external device by an electronic device, the method comprising:
receiving an input that turns on the power of the electronic device; and, transmitting a wake-up signal to the external device to instruct the external device in a standby state to initiate an audio output preparing operation, the standby state corresponding to a state in which the external device attempts to establish a connection.

11 . The method of claim 10 , further comprising transmitting the wake-up signal to the external device and initiating a booting operation of the electronic device in response to the input to turn on the power of the electronic device.

12 . The method of claim 10 , further comprising, periodically receiving connection request signals requesting a connection to the electronic device from the electronic device via the communicator while the external device is in the standby state.

13 . The method of claim 12 , further comprising transmitting a connection success signal to the external device in response to the connection request signals from the electronic device when the electronic device is in a connectable state by completing an operation of booting.

14 . The method of claim 13 , further comprising transmitting audio data to the external device in response to the connection to the external device being established.

15 . A method of controlling power of an audio device, the method comprising:
receiving a wake-up signal from the electronic device while the audio device is in a standby state, the standby state corresponding to a state in which the audio device attempts to establish a connection; and initiating the audio output preparing operation in response to reception of the wake-up signal.

16 . The method of claim 15 , further comprising periodically transmitting connection request signals requesting a connection to the electronic device to the electronic device via the communicator while the audio device is in the standby state.

17 . The method of claim 16 , further comprising outputting audio data received from the electronic device in response to a connection success signal being received in response to the connection request signals.

18 . The method of claim 17 , further comprising displaying, on a display of the audio device, a message notifying that the audio device is turned on in response to a connection success signal being received in response to the connection request signals.

19 . A method of controlling a master communication device, the method comprising:
receiving a power command that instructs the master communication device to enter a power-on state; booting an operation system of the mater communication device in response to the power command; generating a wake-up signal that instructs an external audio device in a standby state to initiate an audio output preparing operation; and transmitting the wake-up signal to the external audio device before the booting is completed.

20 . The method of claim 19 , wherein the audio output preparing operation comprises enabling an audio amplifier circuit of the audio device to be fully powered and stabled.
