The invention provides an electric appliance control method and an electric appliance. The electric appliance comprising a control device and a sound positioning device connected to the control device; and after the electric appliance receives sound control movement information, the sound positioning device determines a transmitting position of the sound control movement information, and the control device controls the electric appliance to move to a position having a predetermined distance away from the transmitting position. The control method can be used to control movable devices such as atower fan or a sweeping robot to move to a designated area, and then control the tower fan to supply air, or controls the sweeping robot to perform cleaning. The electric appliance control method isused to control the electric appliance, so that the control of the electric appliance is more intelligent and humanized, and the human-machine interaction is stronger, and the degree of home intelligence is further improved.
