Title:
VIBRATING ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2016/114384
Kind Code:
A1
Abstract:
In the present invention, a flat movable element vibrates stably in a configuration in which the number of components is reduced and complications in assembly are avoided. A vibrating actuator (1), provided with: a plate-like body (2) made of a magnetic body having a planar supporting surface (2A); a movable element (4) in partial contact with a plurality of locations on the supporting surface (2A) directly or via a contact (3), the movable element (4) vibrating in a uniaxial direction along the supporting surface (2A); an elastic member (7) that elastically rebounds against the vibration of the movable element (4); and a coil (8) fixed to the plate-like body (2), a coil portion (8A) orthogonal to the uniaxial direction being disposed in a gap between the movable element (4) and the plate-like body (2). The movable element (4) is provided with a magnet (9) for forming a magnetic flux and magnetically attracting the movable element (4) toward the supporting surface (2A), the magnetic flux passing through the coil portion (8A) in the coil (8) in a space bounded on one side by the plate-like body (2).
