Abstract
An integral sound module provides a novel isolation system between the display unit and the audio unit. The display unit preferably includes a cathoderay tube (CRT) and associated electronics mounted within a monitor housing. The audio unit comprises a tray member, a cover, and a pair of speakers. The speakers are mounted to the cover by the second isolation means. The first isolation means is disposed on top of the cover of the audio unit to provide for coupling with the bottom of the display unit. The first and second isolation means prevent vibrations from the speakers from being transmitted through the cover and audio unit to the display unit. The cover is also mounted on the tray member to form an audio chamber. The edges of the cover and tray member mate using joints with narrow channels to provide an audio seal that resists the movement of air from within the audio chamber to outside the chamber. The audio seal provided by the joints improves the audio performance of the speakers.
