<p><P>PROBLEM TO BE SOLVED: To output audio by receiving audio data from a DAP even when a PC is in a power off-state. <P>SOLUTION: When a PC 100 is in a power off-state, a power supply voltage is supplied to a cradle 6, a switch 12, a logic IC13 and an amplifier 14. The power supply voltage is supplied to the cradle 6, the switch 12, and the logic IC 13 so that it is possible to control the state of the switch 12 based on whether the DAP 16 is connected to the cradle 6, and whether the PC 100 is set to a power on-state. The power supply voltage is supplied to the amplifier 14 so that it is possible to output a voice from a speaker by amplifying audio data from a DAP 16 even when the PC 100 is in the power off-state. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
