Patent ID: 8818003

Claim:
A mobile terminal, comprising: a sound output module configured to output a sound; a user input unit configured to sense a control command for controlling a volume level of the sound; and a controller configured to: sense an input pattern applied to the user input unit based on a duration for which an input for the control command is applied to the user input unit so as to control the volume level; determine whether the volume level of the sound corresponds to a maximum volume level or a minimum volume level; if the determined volume level corresponds to the maximum volume level, provide a first bounce effect of the sound for a first preset time period between the maximum volume level and a lower volume level corresponding to one predetermined sound level lower than the maximum volume level such that the volume level of the sound changes repeatedly between the maximum volume level and the lower volume level during the first preset time period; and if the determined volume level corresponds to the minimum volume level, provide a second bounce effect of the sound for a second preset time period such that the volume level of the sound changes repeatedly between the minimum volume level and a mute level during the second preset time period.
