57	Abstract	AB	A microelectromechanical system (MEMS) motor includes a substrate, a backplate, and a diaphragm. The substrate has a first surface and a second surface. The second surface has a slot that extends at least partially into the substrate. A port extends through the substrate. The backplate is mounted to the first surface of the substrate, and the backplate covers at least a portion of the port. The diaphragm is between the backplate and the substrate. The diaphragm moves with respect to the backplate in response to acoustic energy that passes through the port.
