摘要：PROBLEM TO BE SOLVED: To provide an audio output device capable ofsuppressing pop noise even when a PWM frequency is switched without stoppingsounding. When switching a PWM frequency, a timing for a correction on time is setinstead of immediately changing from the on time before switching to the on time afterswitching. Then, if the change is such that the on-time after switching becomes longerthan the on-time before switching, the correction on-time is set to be longer than the on-time before switching and shorter than the on-time after switching. .. This makes itpossible to suppress the generation of pop noise even when the PWM frequency isswitched without stopping the sounding. [Selection diagram] Fig. 1
