Abstract
The present invention relates to an apparatus for utilizing a power circuit to amplify voice. The apparatus includes a power circuit and a voice signal processor. The power circuit receives voltage to regulate voltage so as to provide direct current (DC) output voltage. The power circuit includes a feedback stage for performing feedback control to keep stable outputs for the DC output voltage. The voice signal processor receives a voice signal for processing. The characteristic is that the voice signal processor transmits the processing result for the voice signal to the feedback stage in order to change the feedback signal of the feedback stage. The DC output voltage is then changed due to the voice signal, thereby achieving the goal of amplifying the voice signal.
