Abstract
An acoustic imaging device includes a support structure and first and second drivers mounted on first and second faces respectively of the support structure. The first driver projects sound output in a first direction, and the second driver projects sound output in a second direction. The sound output of the second driver is out of phase with sound output of the first driver, and is at a level calculated to reduce substantially sound output from the first driver in a direction other than the first direction.
Claims9
An audio-visual system, comprising
- an image production device for producing an image on a display surface,
- and at least one acoustic imaging device for producing a virtual acoustic image on an acoustic image surface, said acoustic imaging device comprising,
- a support structure,
- a first driver mounted on a first face of said support structure in fixed relationship therewith, for projecting sound output in a first direction toward said acoustic image surface,
- and a second driver mounted on a second face of said support structure in fixed relationship therewith, for projecting sound output in a second direction other than said first direction, said sound output of said second driver being substantially 180.degree. out of phase with sound output of said first driver, and being at a level calculated to reduce substantially sound output from said first driver in a direction other than said first direction,
- wherein said display surface comprises said acoustic image surface.
