System and method for generating high-frequency and mid-frequency audible sound via piezoelectric actuators of a haptic keyboard

A haptic keyboard based sound system of an information handling system, comprising:

• a coversheet to identify a plurality of key locations of a haptic keyboard and a haptic touchpad region of a haptic touchpad;
• a contact foil under the coversheet operatively coupled to a first plurality of piezoelectric elements to generate haptic tactile feedback upon key actuation;
• a second plurality of piezoelectric elements to generate tactile feedback for the haptic touchpad region;
• a haptic sound controller operatively configured to:
• receive an audio signal and send a piezo audio signal to at least one piezoelectric element of the haptic keyboard or haptic touchpad to cause the piezoelectric element to generate sound audio according to the received audio signal.
