MINIATURE LINEAR VIBROTACTILE ACTUATOR

WIPO Patent Application WO/2013/092760

A3

The invention relates to a miniature linear vibrotactile actuator comprising: a first element 14, 104 of generally cylindrical shape, comprising permanent magnets 15, 105 aligned so that two adjacent sides of two adjacent magnets 15, 105 have identical polarities; a second element 11, 101 defining a cylindrical cavity 12, 102 into which the first element 14, 104 is inserted with play so as to be able to slide therein in a sliding direction X2, the second element 11, 101 comprising coils 13, 103 of conductive wire having strands that extend perpendicularly to the sliding direction X2, in order to form magnetic force generators, and that are placed so as to be able to influence the first element 14, 104 electromagnetically; and means 25, 41, 125 for returning and guiding the first element 14, 104 toward an equilibrium position in the second element 11, 101, in which position a median plane P2 between two adjacent magnets substantially coincides with a median plane P1 of a facing force generator 111.
