One of the difficulties with ink jet drivers lies in attempting to control the placement of the zero motion nodal point. The placement is important because it determines where vibration will occur and therefore, what part of system will vibrate with what force. Since it is advisable to be able to maximize or minimize the placement of movement within the structure of a driver assembly, the idea of symmetry is one way to control the nodal point and thus the placement of the maximum drive force.
