Document Type and Number:
Japanese Patent JP7088885
Kind Code:
B2
Abstract:
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 screen, a permanent magnet mounted to the screen, and a magnetic source positioned with respect to the permanent magnet and uncoupled from the screen. The screen is moveable in response to a changing magnetic field from the magnetic source.
