Claim:
1. A method for exchanging control functions of volume control units, wherein the method comprises: obtaining current placement status information of a terminal, wherein the placement status information is used to indicate a current placement status of the terminal, and at least two volume control units are disposed in the terminal; determining, according to the placement status information, whether the current placement status of the terminal deviates from a normal placement status of the terminal; and exchanging volume control functions of the at least two volume control units when the current placement status of the terminal deviates from the normal placement status of the terminal, wherein the at least two volume control units comprise a volume control unit whose volume control function is to control volume to increase and a volume control unit whose volume control function is to control volume to decrease; wherein when a screen of the terminal tilts relative to a horizontal plane and a degree of inclination of the terminal is less than 45 degrees, a placement status of the terminal is the normal placement status of the terminal; wherein the placement status information comprises a deviation angle of the terminal, wherein the deviation angle is an included angle between a line of gravity and a median line of the terminal; and wherein determining, according to the placement status information, whether the current placement status of the terminal deviates from the normal placement status of the terminal comprises:
