Abstract
Entertainment systems are provided including directional sound speakers associated with a media player of the entertainment system; and a directional sound controller associated with the directional sound speakers of the media player. The directional sound controller is configured to direct a sound beam associated with the media player at a defined target region such that the sound beam is only audible within the defined target region and experiences less than about 20 dB of leakage outside the target region during operation of the media player. In-flight entertainment systems and related methods are also provided.
