<p>PROBLEM TO BE SOLVED: To provide a vibrator which can promote miniaturization. SOLUTION: In the vibrator 1, a magnetic circuit section is formed by a pair of magnets 8 arranged side and side and a first yoke 11 and a second yoke 9 opposed to face each other via the magnets 8. A driving coil 12 for making current flow in a direction perpendicular to a direction of a magnetic field is inserted between the magnets 8 and the first yoke 11 and current to the driving coil 12 is controlled by a current controlling section 16. Further a dead-weight 7 is fixed to an outer periphery of the magnet 8 and the dead- weight 7 is supported by a spring member 5. Thereby when current flows through the driving coil 12 at a definite period, the magnet 8, the dead-weight 7 and the second yoke 9 make reciprocal linear vibration in a direction where arranged side by side by cooperation between driving force and pressing force of the spring member 5. In order to increase the reciprocal linear vibration, the device 1 may be extended in the direction where arranged side by side and volume increase of the device 1 can be suppressed.</p> |
