A microphone and orientation sensor system includes a microphone and an orientation sensor. The microphone has a diaphragm. The orientation sensor includes an inertial load member having a first end and a second end opposite the first end. The sensor also includes at least one electrode positioned adjacent to the inertial load member. The sensor further includes a beam. The inertial load member pivots about the beam, and the pivoting of the load member causes a change in a distance between the first end and the electrode resulting in a change in capacitance between the first end and the electrode. The diaphragm and electrode are formed from a common layer of material.
