System and method for generating sound effects on fingertips with piezoelectric actuators of a haptic keyboard

A method of providing haptic sound feedback via a haptic keyboard, comprising:

• receiving a haptic actuation indicator signal via a controller of the haptic keyboard;
• determining, via a haptic feedback keyboard and touchpad control system executing code instructions, a haptic sound feedback control signal for an operating application on a processor of the information handling system and associated with one or more haptic sound feedback settings in a memory;
• sending one or more haptic feedback control signals having the haptic sound feedback control signal, via the controller, to one or more of a plurality of piezoelectric elements placed between a contact foil and a support layer of the haptic keyboard and situated beneath the haptic keyboard;
• receiving a first of the one or more haptic feedback control signals at a first piezo electric element of the plurality of piezoelectric elements of the haptic keyboard;
• and
• generating haptic sound feedback according to the one or more haptic sound feedback settings of the operating application at the first of the plurality of piezoelectric elements in response to the haptic actuation indicator signal.

A haptic keyboard of an information handling system, comprising:

• a coversheet to identify a key location of the haptic keyboard;
• a support layer;
• a contact foil placed between the coversheet and support layer;
• a controller of the information handling system operatively coupled to the contact foil to:
• receive a haptic actuation indicator signal via the contact foil;
• send a haptic tactile movement control signal as part of a combined haptic feedback control signal to a piezoelectric element placed between the contact foil and the support layer to cause the first piezoelectric element to generate haptic tactile movement feedback at the key location in response to the haptic actuation indicator signal;
• and
• send a haptic sound control signal as part of the combined haptic feedback control signal to the piezoelectric element to cause the piezoelectric element to generate haptic sound feedback at the key location in response to the haptic actuation indicator signal.
