Abstract
A method and system for providing a moving-screen sound system for a portable communication device such as a cell phone employs a fixed, pivoted, or hinged display screen driven directly or indirectly by an audio actuator. While the frequency response of the screen may have defects that would negatively impact overall sound quality from the device, in embodiments a supplemental audio transducer is placed adjacent the screen or elsewhere on the device so as to supplement or correct the frequency response of the screen. In an embodiment, the supplemental audio transducer is driven to correct a notch or other defect in the screen response. In another embodiment, the supplemental audio transducer is driven to extend the bass response of the screen.
