Abstract: A portable collapsible seat with an advanced five-driver integral audio system is disclosed. The seat is designed to be used in conjunction with a video screen to create an enhanced "virtual reality" environment. The placement of the drivers relative to the user's head, combined with the intentionally different bandwidths of sound produced by the different drivers, and the relative acoustical intensities of the drivers produces psychologically "gripping" effect, designed to transport the user away from the reality of the actual surroundings and into the virtual reality of the video presentation. One of the drivers is intentionally oriented and positioned to provide tactilly perceivable vibration through the seat to the user.

Abstract: A four-dimensional acoustical audio system utilizes both spatial and temporal signal processing to maximize the depth, width, and perceived directionality of the acoustic field with respect to the binaural auditory system. Transducers are critically placed within the confines of a reverberant enclosure, and each transducer is assigned a specific bandwidth of sound either in mono or stereo, depending upon the spatial location of the transducer to take advantage of the binaural auditory system of the intended listener. The system minimizes the number of transducers and electronics required to achieve the effect of a live performance, regardless of the dynamics of the enclosure in which it is placed. The loudspeaker system can be used in small enclosed volumes such as an automobile or extended to volumes the size of a motion picture theater or concert hall and even outdoors.

Abstract: A loudspeaker apparatus includes an elongated hollow tube having two open ends, which tube may be a rigid or telescoping tube, and has a wide range speaker mounted at each end of the hollow tube. A pair of deflector surfaces may be flat, polymer surfaces mounted to a base and are positioned at an angle facing each speaker at each end of the tube for deflecting the sound waves emanating from each speaker in accordance with the positioning of the tube. The tube may also have a tuned port formed into the side of the tube and connected to an arcuate passageway built into the hollow portion of the inside of the tube for producing a bass resonance from the backwaves of both speakers.
