<p><P>PROBLEM TO BE SOLVED: To provide an audio apparatus and its volume control method whereby it is easy for a user to adjust to a desired volume level, when adjusting a loudness level of sound by using a touch panel. <P>SOLUTION: If an object contacts a volume rise region 31 in an audio apparatus 1; an audio control CPU6 gives an instruction to a volume IC8, and an audible signal is changed so that the volume may become large. If an object contacts a volume down region 32, the audio control CPU6 gives an instruction to the volume IC8, and it changes an audible signal so that the volume may become small. If an object contacts continuously over two or more volume control regions 33 set up between the volume rise region 31 and the volume down region 32, the audio control CPU6 gives an instruction to the volume IC8, the volume is changed a lot rather than when an object contacts the volume rise region 31 or the volume down region 32. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
