VEHICLE LOUDSPEAKER ARRAY

摘要

An audio processing system for a vehicle includes a plurality of loudspeakers positioned to form a single line array (102). The loudspeaker line array (102) is positionable in a vehicle on a dashboard (110) of the vehicle substantially at the convergence of the dashboard (110) and a window (120) of the vehicle. When the loudspeaker line array (102) is driven by an audio signal, a vertically and horizontally focused and narrowed sound pattern is perceived by a listener in the vehicle. The sound pattern is the result of the constructive combination of the direct sound impulses and the reflected sound impulses produced by each loudspeaker in the array. Using delay, attenuation and phase adjustment of the audio signal, the sound pattern may be controlled, limited, and directed to one or more locations in the vehicle.
