• displaying, in the locked state, an image for unlocking the touch screen, at least one application icon, and a virtual key for controlling the audio playback application on the touch screen together when the audible data is being output;
• and
• operating different functions based on whether a drag input is applied to the application icon or a touch input is applied to the virtual key,
• wherein a first function related to the drag input applied to the application icon is performed to display an execution screen corresponding to the application icon, in response to a release of the drag input of the application icon, and
• wherein a second function related to the touch input applied to the virtual key is performed to control an output of the audible data while the locked state is maintained.
