Asymmetric Horn Waveguide Aiming for Even Cinema Sound Coverage

The patent applies asymmetry by designing a horn waveguide with non-uniform cross-sectional dimensions where the width and height vary differently along the horn's length. Specifically, the horn has a first dimension that tapers at a first rate and a second dimension that tapers at a second rate, creating an asymmetric geometry that optimizes acoustic wave propagation and provides even spectrum coverage across all frequency ranges and seating areas.

The patent applies parameter changes by precisely controlling the taper rates of the horn's dimensions. The first dimension tapers at a first rate while the second dimension tapers at a second rate, with specific relationships between these rates optimized to maintain acoustic energy efficiency. This parameter optimization ensures that the horn provides wide coverage area while maintaining high sensitivity by preventing energy loss and ensuring efficient sound wave propagation throughout the venue.

The patent applies dynamics by creating a horn waveguide whose acoustic characteristics dynamically adapt to different listening positions. The asymmetric tapering creates a coverage pattern that naturally transitions from narrow at the source to wider at distance, providing both long throw capability for distant listeners and adequate coverage for closer sections without requiring multiple speaker systems or compromising sensitivity.
