1. A method of forming a transducer comprising the acts of:
- forming a structural bottom plate from a first sheet of metal material;
forming a structural top plate from a second sheet of metal material;
forming a middle portion comprising a mid-upper element and a central element, including the acts of;
forming the mid-upper element from a third sheet of material, the mid-upper element comprising a mid-upper frame, a mid-upper mass, and a plurality of mid-upper attachment members coupling the mid-upper mass to the mid-upper frame;
forming the central element from a fourth sheet of material, the central element comprising a central frame and a central mass;
coupling the mid-upper mass and the central mass together to form a combined mass; and
coupling the mid-upper frame and the central frame together to form a combined frame;
coupling the combined frame to the top plate such that a first capacitance is provided between the combined mass and the top plate; and
coupling the combined frame to the bottom plate such that a second capacitance is provided between the combined mass and the bottom plate.
