1. An information handling system comprising:
an outer housing;
a processor disposed in the outer housing, the processor being configured to execute instructions to process information;
a memory disposed in the outer housing, the memory being configured to store the information;
a piezoelectric transducer disposed in the outer housing and mechanically coupled to a first side of a surface held by the outer housing;
a sensor disposed in the outer housing and configured to generate a signal indicative of user presence in a zone proximate to the piezoelectric transducer and above a second side of the surface;
a first subsystem;
a second subsystem;
a second piezoelectric transducer; and
a controller disposed in the outer housing,
wherein in a dynamic mode of operating the information handling system, the controller configures the piezoelectric transducer to be responsive to the first subsystem if the signal indicates a user is absent from a zone proximate to the information handling system, and configures the piezoelectric transducer to be responsive to the second subsystem if the signal indicates a user is present in the zone proximate to the information handling system,
wherein the controller configures the piezoelectric transducer to be responsive to the second subsystem in response to the user being present in the zone proximate to the piezoelectric transducer and the controller configures the second piezoelectric transducer to be responsive to the first subsystem in response to the user being absent from an additional zone proximate to the second piezoelectric transducer.
