摘要 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.
