The speaker unit is electrically connected to the control circuit unit to obtain audio signal via the audio port. The two power-storing units store power from the external power source, and include a first power-storing unit for driving the speaker unit and a second power-storing unit for electrically connecting to the discharging port to allow charging power stored in the second power-storing unit to charge into the portable electronic device connected to the discharging port.
