DEVICE FOR CHANGING SURFACE OF ELECTRONIC DEVICE USING ELECTROMAGNETIC ELEMENTS Russian patent published in 2021 - IPC G06F3/46 

FIELD: electrical equipment.

SUBSTANCE: device belongs to electrical equipment. A device for tactile action and transmission of information with a changing surface shape through the interaction of at least two electrical elements controlled by the controller, consisting of a housing with a fixed part, as well as moving elements that change the shape of the device surface by moving these elements relative to the housing due to electric, magnetic or electromagnetic interaction of electrical elements, at least one of which can act on a movable element, being this movable element, being a part of it or having a mechanical connection with it, characterized in that at least part of the surface of the stationary part of the housing is covered with an elastic material; at least one electrical element is attached to a fixed part of the housing; also at least one more electrical element is movable relative to the housing; a movable electrical element is located in such a way relative to an eclectic element attached to a fixed part of the housing, which can move under the forces arising according to Coulomb's law, Ampere's law and/or the Lorentz Force, as a result of the electric, magnetic or electromagnetic interaction of these elements; The movable electrical element is located between the fixed part of the housing and the elastic material in such a way that, as a result of its movement caused by the specified interaction with the electrical element attached to the fixed part of the housing, it changes the surface shape of the elastic material.

EFFECT: increasing tactile impact, interactivity and quality of feedback.
