Directional audio array apparatus and system

摘要

A directional transducer array system comprising a plurality of transducers with mathematical sequence spacing mounted on an array tile or host device. In an embodiment, the invention allows the construction of a receiving or transmitting, tiled (modular) directional audio array while simultaneously retaining desirable directional characteristics, improving gain, and limiting negative impacts on side lobe attenuation as the array is scaled (i.e. identical or similar tiles are added to or subtracted from the array); and allows the construction of a receiving or transmitting directional audio array that is light weight and robust enough to be used in body-worn, body-carried, vehicular, and fixed installations.

主权项

1. A directional transducer array apparatus comprising:
a printed circuit board substrate, the printed circuit board substrate being configured in a polyhedron shape such that the printed circuit board substrate is capable of being interconnected with one or more additional printed circuit board substrates; a plurality of transducers mounted on a surface of the printed circuit board substrate configured such that spacing between each transducer in the plurality of transducers is defined according to a fractal-based mathematical sequence; at least one input-output connector operably engaged with the plurality of transducers through an electrical bus; and, at least one dual in-line package switch operable to select channel settings on an electronics module.
