Abstract

A mobile terminal can include a display; a proximity sensor to sense proximity of an object; an audio output unit; a microphone unit; and a controller to: in response to sensing the proximity of the object through the proximity sensor, activate the microphone and activate a voice recognition function, and in response to receiving a first voice signal for requesting first event information through the microphone, execute a first function of an application corresponding to first text converted from the first voice signal, and output audio data based on an execution of the first function.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a display;
a proximity sensor configured to sense proximity of an object;
an audio output unit;
a microphone unit; and
a controller configured to:
in response to sensing the proximity of the object through the proximity sensor, activate the microphone and activate a voice recognition function, and
in response to receiving a first voice signal for requesting first event information through the microphone, execute a first function of an application corresponding to first text converted from the first voice signal, and output audio data based on an execution of the first function,
wherein the proximity of the object is sensed by the proximity sensor while the display is in a deactivated state, and the first function executes while maintaining the display in the deactivated state.

2. The mobile terminal of claim 1 , wherein the controller is further configured to:
in response to receiving a second voice signal for changing the first function, cancel execution of the first function of the application and execute a second function of the application corresponding to second text converted from the second voice signal.

3. The mobile terminal of claim 1 , wherein the controller is further configured to:
in response receiving a second voice signal for canceling execution of the first function, cancel execution of the first function of the application based on second text converted from the second voice signal.

4. The mobile terminal of claim 1 , wherein the controller is further configured to:
display a lock screen on the display, and
in response to sensing the proximity of the object through the proximity sensor, activate an interface for receiving security information for releasing the lock screen.

5. The mobile terminal of claim 1 , wherein the controller is further configured to:
display a lock screen on the display, and
in response to sensing the proximity of the object through the proximity sensor, output only audio data corresponding to information of a preset event among multiple events.

6. A method of controlling a mobile terminal, the method comprising:
in response to sensing a proximity of an object through a proximity sensor, activating a microphone in the mobile terminal and activating a voice recognition function; and
in response to receiving a first voice signal for requesting first event information through the microphone, executing a first function of an application corresponding to first text converted from the first voice signal, and outputting audio data through an audio output unit in the mobile terminal based on an execution of the first function,
wherein the sensing of the proximity of the object by the proximity sensors occurs while a display of the mobile terminal is in a deactivated state, and the executing of the first function occurs while maintaining the display in the deactivated state.

7. The method of claim 6 , further comprising:
in response to receiving a second voice signal for changing the first function, canceling execution of the first function of the application and executing a second function of the application corresponding to second text converted from the second voice signal.

8. The method of claim 6 , further comprising:
in response receiving a second voice signal for canceling execution of the first function, canceling execution of the first function of the application based on second text converted from the second voice signal.

9. The method of claim 6 , further comprising:
displaying a lock screen on a display of the mobile terminal; and
in response to sensing the proximity of the object through the proximity sensor, activating an interface for receiving security information for releasing the lock screen.

10. The method of claim 6 , further comprising:
displaying a lock screen on a display of the mobile terminal; and
in response to sensing the proximity of the object through the proximity sensor, outputting only audio data corresponding to information of a preset event among multiple events.
