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.

Claims

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.
