Abstract
An inductor driving device includes multiple switching elements and a control circuit, wherein an inductor is driven according to switching of the multiple switching elements. The control circuit is arranged to generate a control signal for controlling the multiple switching elements. In a first mode, the control signal has a constant frequency. In a second mode, the control circuit adjusts a frequency of the control signal and continuously changes a current direction of the inductor, to generate one of multiple audio signals through the inductor.
