Abstract

The invention discloses a loudspeaker box power amplifier which comprises a rear D-type digital power amplifier, a middle D-type digital power amplifier and a front D-type digital power amplifier. The power of the rear D-type digital power amplifier is larger than the power of the middle D-type digital power amplifier and the power of the front D-type digital power amplifier. The power of the middle D-type digital power amplifier is larger than or equal to the power of the front D-type digital power amplifier. The power of the front D-type digital power amplifier, the power of the middle D-type digital power amplifier and the power of the rear D-type digital power amplifier are different, so that the stereoscopic impression of output sound is enhanced.

Description
