The present invention discloses a high-efficiency low-voltage-power-supply high-power-output audio driver architecture, including: a multi-coil loudspeaker; and a single-input N-output audio power amplifier configured to amplify a received digital audio signal and to output N switch signals for driving the multi-coil loudspeaker, wherein N represents the number of output channels and is a positive integer greater than or equal to 2. By implementing the above mentioned method, the requirement of the high power output under low voltage input is met; the solution improves the output power by means of combination of coils, and, in cooperation with the unique dynamic power allocation technology, the solution achieves the power balance of the multiple coils, so that the output efficiency of the audio driver is greatly improved.
