Abstract
An acoustical sensor can include a fabricated surface that produces an acoustical sound signature responsive to a finger tapping on the fabricated surface, and a microphone within proximity of the fabricated surface to analyze and associate the acoustical sound signature with a user interface control for operating a mobile device or earpiece, for example, to adjust a volume, media selection, or user interface control. The microphone can include an ultra-low analog circuit to set a capacitance and establish a frequency response, the analog circuit programmable to identify a direction of a directional touch or localized touch on the fabricated surface. The analog circuit by way of a floating gate can control a real delay between a front and back diaphragm to control microphone directivity. Other embodiments are disclosed.
