Abstract
Disclosed is a hybrid power supply-based high-power loudspeaker box, and a power-supplying method for increasing the power of the loudspeaker box. A battery power-supplying unit and a power supply power-supplying unit are arranged in a power supply management module to supply power for a power amplification unit, an audio input unit receives input audio, the power amplification unit amplifies an audio signal, and the amplified audio signal drives a loudspeaker to make a sound so as to meet high-power output of the loudspeaker box. The power-supplying method is suitable for the high-power loudspeaker box. High power exceeding the power supply power is output under a condition that a powered voltage of the power supply power-supplying unit is constant.
