Abstract
An orientation adjusting apparatus for a speaker set has a moving device, which is received in a housing, and includes a first motor, a second motor, a co-moving wheel, and an up and down movably frame biased upwards by springs. The first motor comes into contact with a top of the frame at a depressing wheel thereof. The second motor is secured to the frame, and has a second wheel. The co-moving wheel is connected to the frame. When the first, and the second motors are activated, the frame will be moved down by means of the depressing wheel for both the second wheel and the co-moving wheel to stick out from the bottom of the housing to come into contact with the ground, and the housing will be moved left and right by means of the second wheel with a rear support leg thereof as a pivot.
