Abstract
Methods, apparatuses, and systems are disclosed for a transducer. The transducer can include a bottom plate formed from a first sheet of material, a top plate formed from a second sheet of material, and a middle portion. The middle portion includes a mid-upper element formed from a third sheet of material, with 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. The middle portion can also include a central element formed from a fourth sheet of material, with the central element having a central frame and a central mass.

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.
A transducer, comprising:
- a bottom plate formed from a first sheet of non-semiconductor material;
- a top plate formed from a second sheet of non-semiconductor material;
- and
- a middle portion, the middle portion comprising:
- a mid-upper element formed 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;
- and
