Abstract
A system may include a vibrating surface, a single mechanical transducer mechanically coupled to the vibrating surface, a signal processing subsystem configured to receive an audio signal and a haptic signal, process the audio signal and the haptic signal to generate a combined audio-haptic signal, and drive the combined audio-haptic signal to the single mechanical transducer in order to generate concurrent audio playback and haptic effects on the vibrating surface; and a control subsystem configured to, responsive to a haptic stimulus, modify at least one parameter of at least one of the audio signal and the haptic signal to accommodate the concurrent audio playback and haptic effects on the vibrating surface within at least one operational limit of the system.
