Abstract
A linear actuator includes a mover equipped with an outer yoke and a magnet, a stator equipped with coils and an inner yoke, and leaf springs for linking the movable section and the stator. The actuator is assembled such that the leaf springs are deformed when the mover stays at a balanced position. This structure can maximize a vibration stroke of the mover.
Claims7
A vibrating linear actuator comprising:
- a mover including a permanent magnet;
- a stator including a coil which generates a vibrating magnetic field that vibrates said mover;
- and
- an elastic body, for linking said stator to said mover and being assembled to the actuator such that said elastic body is deformed when said mover stays at a balanced position.
