Summary:PROBLEM TO BE SOLVED: To provide a mobile sound output apparatus driven by a battery a consumed output of which can be reduced. SOLUTION: A power supply section 12 charges the battery 14 when receiving supply of power from a reproduction apparatus and carries out driving by the battery 14 when receiving no power supply. When the power supply section 12 detects no supply of power from the reproducing apparatus, a wireless interface section 11 sets a wireless channel to the reproduction apparatus and receives sound data from the reproducing apparatus via the wireless channel. On the other hand, when the reception of power supply is detected, the wireless interface section 11 interrupts the wireless channel to the reproducing apparatus. COPYRIGHT: (C)2005,JPO&NCIPI
