Acoustic Holographic Recording and Reproduction System Using Meta Material Layers

Abstract

Holographic sound is recorded and reproduced by way of a single monaural recording per left and right ear recorded. This is accomplished by determining the phase shift of frequencies recorded after dividing the sound into discrete frequencies in a recording device having resonators, each resonating at a different frequency, placed in a circular arrangement and divided into discrete channels by non-resonant material. The resonators are placed in a pseudo-randomized arrangement within the recording device and the circle of resonators is in front of a microphone which records the sound monaurally. Playback is then by way of arranging speakers or transducers into micro perforated sheets which amplify the sound, the arrangement of speakers/transducers around a central point. The sound is then played back directionally based on the position where the sound originally was recorded from and the position of the particular transducer around the central point.

1 - 10 . (canceled) 
     
     
         11 . A device for receiving and reproducing sound in three dimensions, comprising:
 a plurality of resonators, each which resonates at a different frequency, arranged in a substantially circular arrangement;   a microphone situated between said plurality of resonators on at least one plane of a three dimension plane;   a tangible storage medium storing a digital version of said sound after applying compressed sensing to output from said microphone;   a plurality of flat-surfaced piezo-drivers arranged equi-distant from a center point on a sound reproduction device having at least eight equal sides, playing back an uncompressed version of said output from said microphone with output to specific piezo-drivers of said plurality of piezo-drivers based on a determined phase shift of at least some frequencies within said output and an orientation of said specific piezo-driver of said plurality thereof.   
     
     
         12 . The device of  claim 11 , wherein a directionality of sound recorded by said microphone is reproduced by said piezo-drivers which cause vibrations through acoustic meta material layers attached to said sound reproduction device. 
     
     
         13 . The device of  claim 11 , comprising an additional and substantially identical set of said plurality of resonators, said microphone, and said plurality of piezo-drivers such that output from said microphone and an additional said microphone records sound in binaural or stereo and playback by said plurality of piezo-drivers and additional said plurality of piezo-drivers allows for detection of a position of sound picked up by said microphone and said additional said microphone to be aurally determined in three-dimensional space relative to said plurality of piezo-drivers and said additional piezo-drivers. 
     
     
         14 . The device of  claim 11 , wherein said plurality of piezo-drivers are each attached to a single said sound reproduction device which amplifies sound of said piezo-drivers. 
     
     
         15 . The device of  claim 14 , wherein spacing of said piezo-drivers has no correspondence with spacing of said plurality of resonators. 
     
     
         16 . The device of  claim 11 , wherein said plurality of resonators are pseudo-randomly arranged in said substantially circular arrangement. 
     
     
         17 . The device of  claim 16 , wherein said plurality of resonators are bifurcated by a plurality of equi-spaced non-resonant material arranged within said circular arrangement. 
     
     
         18 . The device of  claim 11 , wherein said microphone is monaural and said storage medium stores sound received therefrom in a single channel of data in said compressed version.
