Abstract
A portable electronic device includes a combination button and a gravity sensor. The gravity sensor detects gravity variation of the portable electronic device. When the combination button is pressed for a first predetermined time, the gravity sensor begins. When the combination button is pressed within a second predetermined time and the gravity sensor detects no gravity variation, the combination button's power switch function shuts down the portable electronic device. If the gravity sensor detects a gravity variation, the combination button's volume adjusting function can increase or decrease the volume of the portable electronic device according to the gravity variation.
