An electronic device (50) is provided with a magnetostrictive device (30) and a main body (40). The magnetostrictive device (30) includes a supermagnetostrictive element (1) which expands and contracts corresponding to magnetic field, a coil (4) and biasing magnet (2) for generating magnetic field, and a housing (8) for holding the element, coil and the magnet at prescribed positions. The magnetostrictive device (30) is attached to the main body (40) to permit the supermagnetostrictive element (1) to orthogonally intersect with the attaching plane of the main body (40). A prescribed pressure is applied to the supermagnetostrictive element (1) by the main body (40) and the housing (8) by connecting the housing (8) to the main body (40).
L'invention concerne un dispositif électronique (50) comportant un dispositif magnétostrictif (30) et un corps principal (40). Le dispositif magnétostrictif (30) comprend un élément supra-magnétostrictif (1) qui se dilate et se contracte au gré du champ magnétique, une bobine (4) et un aimant de polarisation (2) générant un champ magnétique, et un boîtier (8) maintenant l'élément, la bobine et l'aimant dans des positions spécifiées. Le dispositif magnétostrictif (30) est fixé à l'élément principal (40) de manière que l'élément supra-magnétostrictif (1) coupe orthogonalement le plan de fixation du corps principal (40). Lorsqu'ils sont raccordés l'un à l'autre, le boîtier (8) et le corps principal (40) appliquent une pression déterminée à l'élément supra-magnétostrictif (1).
