Directed acoustic sound system
First Claim
1. A method of providing directed acoustic sound in an electronic entertainment system having a non-directional audio speaker system, comprising the steps of:
- providing, by the electronic entertainment system, one or more audio signals to a directed acoustic sound system, the directed acoustic sound system being connected in-line with the non-directional audio speaker system so as to provide the one or more audio signals to the non-directional audio speaker system, the directed acoustic sound system and the non-directional audio speaker system being selectable by a user of the electronic entertainment system;
in response to a first user selection of the directed acoustic sound system;
suppressing, by the directed acoustic sound system, the one or more audio signals at the non-directional audio speaker system;
generating a sound beam from the one or more audio signals by the directed acoustic sound system; and
projecting, by the directed acoustic sound system, the sound beam through the air along a pre-selected path to reproduce the one or more audio signals along at least a portion of the pre-selected path, thereby providing the user disposed substantially in the portion of the pre-selected path wire with a private listening experience; and
in response to a second user selection of the non-directional audio speaker system;
reproducing the one or more audio signals by the non-directional audio speaker system.

Abstract
An acoustic sound system usable in electronic entertainment systems that generates highly directional sound. The directed acoustic sound system includes a parametric audio sound system having a modulator for modulating an ultrasonic carrier signal with a processed audio signal, a driver amplifier for amplifying the modulated signal, and a parametric loudspeaker for projecting the modulated and amplified signal through the air for subsequent regeneration of the audio signal along a pre-selected path. The acoustic sound system allows a user to select the parametric loudspeaker, a connectable non-directional loudspeaker, or both loudspeakers for producing audible sound. The acoustic sound system may be employed in the home, in the workplace, or in any other environment where audio leakage is undesirable.
