Abstract
There is described herein a diffuser assembly comprising a leaf spring, diffuser and at least one actuator. The leaf spring is arranged as a rectangular frame having a width, x, and height, y. The diffuser is suspended by the frame such as within the frame. The at least one actuator arranged to move, such as translate, the diffuser. The assembly is arranged such that the leaf spring provides in-plane (x-y plane) stiffness, kx and ky, less than the out-of-plane (z-direction) stiffness, kz.
Claims18
A diffuser assembly comprising:
- a leaf spring arranged as a rectangular frame having a width and height;
- a diffuser suspended within the frame;
- and
- a first actuator attached to a side of the diffuser and a second actuator attached to an opposite side of the diffuser, wherein the first and second actuators are arranged to move the diffuser such that the movement of the diffuser is substantially in-plane, wherein the assembly is arranged such that the leaf spring provides in-plane stiffness less than the out-of-plane stiffness, and wherein each of the first and second actuators is a motor having a stator attached to the diffuser and a rotor having a spinning eccentric load.
