Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that move a display screen to produce sound or haptic feedback. A first force that causes a first movement of a first portion of a display screen is applied by a first transducer that is mechanically coupled to the first portion of the display screen. A movement of a second portion of the display screen is detected by a second transducer that is mechanically coupled to the second portion. A relationship between the first movement caused at the first portion of the display screen by the first transducer and the movement detected at the second portion of the display screen by the second transducer is determined. A second force that causes a second movement of the first portion of the display screen is applied by the first transducer, the second force being determined using the determined relationship.
