Abstract
A suspension assembly comprises a load beam including a proximal end terminating in a hinge, a gimbal assembly mounted to the load beam, a base plate, and PZT actuators. The base plate comprising a distal portion connected to the hinge, a proximal portion, and a neck portion disposed between the distal portion and the proximal portion, wherein the neck portion comprising side edges facing away from each other, wherein the side edges, the distal portion and the proximal portion define openings, wherein each of the side edges includes a protrusion at a center of the neck portion facing one of the openings. Each of the PZT actuators is disposed in one of the openings and mounted to the proximal portion and the distal portion.
