Tactile fixing device for electromagnetic chip, has network of monolithic units for modification of sensation on key surface and including mobile blade assembly, where each blade is submissive to magnetic field produced by magnetic spools

摘要

The device has a keyboard with a network of monolithic units for modification of a tactile sensation (11) on surface of a key (16). The network has an assembly of mobile blades (12), where each blade shifts under action of a magnetic field and is submissive to a field produced by magnetic spools (31). An intermediary isolated layer is held between a monolithic layer of spools and the keyboard. The isolated layer has a sink with respect to each of the units for modification of the sensation and procures a space of deformation for the blade assembly.
