SOUND VOLUME CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sound volume control method for solving conventional problems. SOLUTION: The sound volume control method comprises the steps of: receiving a sound volume adjusting command (a); judging whether or not the sound volume corresponding to the sound volume adjusting command is settled within a predetermined sound volume range (b); adjusting the current sound volume in accordance with the sound volume adjusting command if the sound volume corresponding to the sound volume adjusting command is settled within the predetermined sound volume range (c); adjusting the current sound volume in accordance with the sound volume adjusting command (d1) if the sound volume corresponding to the sound volume adjusting command is not settled within the predetermined sound volume range (d); and computing a duration of the adjusted current sound volume and further adjusting the current sound volume by referring to the predetermined sound volume range when the duration reaches a predetermined value (d2).
