Abstract
In some examples, a transducer apparatus includes a spring structure that enables a large, reliable amount of displacement of a transducer plate. For instance, an individual cell of the transducer apparatus may include a substrate having a first electrode portion, with at least one spring anchor extending from a first side of the substrate. At least one spring member may be supported by the at least one anchor, and may be connected to a plate that includes a second electrode portion. Accordingly, the spring member may support the plate, at least in part, for enabling the plate to move in a resilient manner toward and away from the substrate. In some cases, the spring member may be a bar-shaped spring that is cantilevered to an anchor or supported by two or more anchors. Additionally, a cavity between the plate and the substrate may be sealed by a sealing material.
