Abstract
An electronic device is provided with a magnetostriction apparatus and a main body. The magnetostriction apparatus includes a super magnetostrictor which extracts and contracts in accordance with a magnetic field, a coil and bias magnets which generate the magnetic field, and a housing which maintains the components at predetermined positions. The magnetostriction apparatus is fitted to the main body such that the super magnetostrictor is perpendicular to the face of the main body where the apparatus is fitted. The housing is connected to the main body so that a predetermined pressure is applied to the super magnetostrictor by the main body and the housing.
Claims9
A magnetostriction apparatus comprising:
- a magnetostrictor which expands and contracts in accordance with a magnetic field;
- a magnetic field generating means which generates the magnetic field;
- and
- a housing which holds the magnetostrictor and the magnetic field generating means at predetermined positions, wherein the housing is connected to an external member so that a predetermined pressure is applied to the magnetostrictor by the external member and the housing.
A magnetostriction apparatus comprising:
- a magnetostrictor the magnetic characteristic of which varies in accordance with variation applied from outside;
- detecting means which detects variation in the magnetic characteristic in the form an electrical signal;
- a housing which holds the magnetostrictor and the detecting means at predetermined positions, wherein the housing is connected to an external member so that a predetermined pressure is applied to the magnetostrictor by the external member and the housing.
