<p>An electronic device 50 is provided with a magnetostriction apparatus 30 and a main body 40. The magnetostriction apparatus 30 includes a super magnetostrictor 1 which extracts and contracts in accordance with a magnetic field, a coil 4 and bias magnets 2 which generate the magnetic field, and a housing 8 which maintains the components at predetermined positions. The magnetostriction apparatus 30 is fitted to the main body 40 such that the super magnetostrictor 1 is perpendicular to the face of the main body 40 where the apparatus is fitted. The housing 8 is connected to the main body 40 so that a predetermined pressure is applied to the super magnetostrictor 1 by the main body 40 and the housing 8.</p> |
