The mode control key 25 is used for controlling the output voltage of the charging voltage regulating and managing unit 22, and the switching unit 12 is used for selecting to transmit the audio data received by the bluetooth chip 11 to the first playing unit 14 or the second playing unit 26 or not to output the audio data for charging only according to the magnitude of the output voltage. The charging voltage regulating and managing unit 22 not only manages charging of the speaker battery 23, but also regulates output voltages of the speaker battery 23 to the second transmission connector 27, the first transmission connector 15, and the earphone battery 13. And the adjustment of the output voltage is triggered by the mode control key 25. That is, when the mode control key 25 is pressed, the output voltage of the charge voltage regulating management unit 22 is changed.
