Abstract
(EN)
A magneto mechanical resonator device comprises a plurality of ferromagnetic elements disposed in a stacked arrangement, each ferromagnetic element having a first lengthwise end and a second lengthwise end. A first bias magnetic element is disposed adjacent to the first lengthwise end of the stacked arrangement and a second bias magnetic element is disposed adjacent to the second lengthwise ends of the stacked arrangement. A clamping element is disposed in a central lengthwise region of the stacked arrangement to restrict the vertical displacement of the plurality of ferromagnetic elements with respect to each other at the central lengthwise region, wherein the first and second ends experience flaring movement.

La présente invention concerne un dispositif à résonateur magnétomécanique comprenant une pluralité d'éléments ferromagnétiques disposés dans un agencement empilé, chaque élément ferromagnétique ayant une première extrémité longitudinale et une seconde extrémité longitudinale. Un premier élément magnétique de polarisation est disposé de manière adjacente à la première extrémité longitudinale de l'agencement empilé et un second élément magnétique de polarisation est disposé de manière adjacente à la seconde extrémité longitudinale de l'agencement empilé. Un élément de serrage est disposé dans une zone longitudinale centrale de l'agencement empilé pour limiter le déplacement vertical de la pluralité d'éléments ferromagnétiques les uns par rapport aux autres au niveau de la zone longitudinale centrale, les première et seconde extrémités subissant un mouvement d'évasement.
