Abstract
The invention relates to a miniature linear vibrotactile actuator comprising: a first elementof generally cylindrical shape, comprising permanent magnetsaligned so that two adjacent sides of two adjacent magnetshave identical polarities; a second elementdefining a cylindrical cavityinto which the first elementis inserted with play so as to be able to slide therein in a sliding direction X, the second elementcomprising coilsof conductive wire having strands that extend perpendicularly to the sliding direction X, in order to form magnetic force generators, and that are placed so as to be able to influence the first elementelectromagnetically; and meansfor returning and guiding the first elementtoward an equilibrium position in the second element, in which position a median plane Pbetween two adjacent magnets substantially coincides with a median plane Pof a facing force generator
