TRANSPARENT VIBRATING TOUCH INTERFACE

摘要

The invention relates to a touch interface (800) comprising a contact surface and means for vibrating the contact surface, said means being provided to generate standing waves in said surface. The contact surface includes at least one transparent portion forming a surface for seeing through the touch interface (800), and the vibration generating means include at least one rigid piezoelectric layer that is rigidly connected to the contact surface and disposed on the periphery of the transparent portion. The interface (800) is characterized in that the at least one piezoelectric layer (800) is disposed in a plane that is not parallel to the contact surface. The invention also relates to a display screen using such an interface, and to an electric appliance using such a display screen.
