Document Type and Number:
WIPO Patent Application WO/2019/102704
Kind Code:
A1
Abstract:
The present invention reduces a leakage magnetic flux and suppresses swinging of a movable element in the intersecting direction with respect to a desired vibration direction. The present invention is provided with: a movable element 10 integrally having a weight body 11 and a coil 12; an elastic body 20 that supports the movable element 10 such that the movable element can vibrate; a first magnet 30 that faces the coil 12 on one side in the intersecting direction with respect to the vibrating direction of the movable element 10; a second magnet 40 that faces the coil 12 on the other side in the intersecting direction; and magnetic members 51, 52 that fix the magnets, respectively. The movable element 10 is vibrated due to a magnetic force that is generated when the coil 12 is energized.
