Abstract:
A method for mechanically driving a display screen to produce acoustic sound may include mechanically driving a first mechanical transducer mechanically coupled to the display screen to generate acoustic sound from the display screen and controlling a second mechanical transducer mechanically coupled to the display screen at a specific location to apply an acoustic null to the specific location in order to localize generation of the acoustic sound from the display screen.
