Multidimensional stereophonic sound reproduction system

A system for reproduction of an audio program which preserves the relative position of each sound source in the programs aural image, comprising:

• a first two-point microphone for converting a first two-dimensional vector sound wave to a first two-dimensional vector electronic wave;
• a second two-point microphone for converting a second two-dimensional vector sound wave to a second two-dimensional vector electronic wave;
• a first two-point loudspeaker for converting said first two-dimensional vector electronic wave into a left channel sound wave;
• a second two-point loudspeaker for converting said second two-dimensional vector electronic wave into a right channel sound wave;
• a substantially planar sound screen having a periphery and having a first surface and an opposing second surface separated by a thickness equal to a fraction of a selected acoustic wavelength;
• support means for exerting tensile forces about the periphery of the sound screen;
• means aiming said first two-point loudspeaker to direct said left channel sound wave as a diffused sound incident upon a majority of the sound screen, thereby generating first forced bending waves of the screen, which propagate within the plane of the sound screen;
• means aiming said second two-point loudspeaker to direct said right channel sound wave as a diffused sound incident upon a majority of the sound screen, thereby generating second forced bending waves of the screen, which propagate within the plane of the sound screen;
• said tensile forces being sufficient to cause said first and second forced bending waves to generate an interference within the sound screen, said interference generating an interference sound wave which propagates toward the listening position.
