An inkjet nozzle assembly includes a substrate. A drive circuitry layer is positioned on the substrate An inkjet nozzle is mounted to the substrate and defines an ink chamber. The nozzle includes a fixed portion that extends from the substrate, and a movable portion that defines an ink ejection port and which is displaceable with respect to the fixed portion. At least two actuating arrangements are operatively positioned with respect to the movable portion and configured to receive an electrical drive signal from the drive circuitry layer and to move the movable portion with respect to the fixed portion so as to vary the volume of the ink chamber. The actuating arrangements are positioned to exert a resultant, substantially vertical force on the movable portion with respect to the substrate.
