Abstract
An audio playing device may operate in a first mode or a second mode. The audio playing device includes a speaker, an earphone jack receiving an earphone plug of an earphone, a sound output driver, a rotation angle detector, and a processor. The sound output driver only drives the speaker when the audio playing device operates in the first mode and only drives the earphone when the audio playing device operates in the second mode. The rotation angle detector generates a first mode change signal when the earphone plug is rotated in the earphone jack along a first direction over a predetermined angle. The processor changes operation of the audio playing device between the first mode and the second mode when the processor receives the first mode change signal from the rotation angle detector.
