Abstract
Screen vibration systems are provided that can vibrate theatre screens 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 screen, a permanent magnet mounted to the screen, and a magnetic source positioned with respect to the permanent magnet. The screen is moveable in response to a changing magnetic field from the magnetic source.
