Screen vibration systems are provided that can vibrate theatre screens using acoustical, electromagnetic, or another type of energy while reducing the presence of image artifacts that may otherwise be visible as result of vibrating the screen. In one example of a screen vibration system, the system includes a controller and an electromechanical acoustical actuator with an open baffle. The electromechanical acoustical actuator can be uncoupled from the screen in an operational setup. The controller can provide a signal to the electromechanical acoustical actuator for causing the electromechanical acoustical actuator to output energy to displace air that is (i) in front of the electromechanical acoustical actuator and (ii) between the electromechanical acoustical actuator and the screen. The open baffle can prevent displaced air behind the electromechanical acoustical actuator from affecting the screen.
