Abstract:
An acoustical system for converting sound waves into corresponding signals for use in acoustic data storage and/or driving a speaker, said system comprising:a housing, said housing comprising a first guide member and a second guide member, said first guide member having a peripheral edge and an inner region, and said second guide member having a peripheral edge and an inner region, said first guide member being positioned proximate said second guide member, and being shaped relative to said second guide member such that the distance between said first guide member inner region, and said second guide member inner region is substantially less than 22 degrees and the distance between said first guide member inner region and said second guide member inner region and the space between said first guide member peripheral edge and said second guide member peripheral edge forms a sound channel having a sound wave entrance port, a sound transducer for converting sound waves into electrical signals, and said transducer being positioned substantially flush with the surface of said first guide member inner region, and positioned to be responsive to sound waves which travel downstream, from said entrance port, wherein said sound channel extends from said sound wave entrance port, past said transducer, such that sound waves do not substantially reverse direction and travel toward said sound wave entrance port.
