Sound system

Abstract

A sound or acoustic system constructed entirely of magnetically inert components which remain unaffected by magnetic fields. A magnetically inert panel is provided, with at least one magnetically-inert transducer being mounted upon this panel. At least one hollow channel extends into the panel from an edge thereof, while a hole is positioned within the panel to communicate at one end with the channel and to open at an opposite end adjacent the transducer.

What is claimed is: 
     
       1. A sound system constructed entirely of magnetically inert .Iadd.rf-shielded .Iaddend.components which remain unaffected by magnetic fields and do not affect imaging quality, said system comprising a magnetically inert panel,   at least one pair of magnetically-inert transducers mounted upon said panel one of which is a high-frequency transducer and the other of which is a low frequency transducer,   at least one hollow channel extending into said panel from an edge thereof,   .[.an rf-tight enclosure,   means to mount said panel in said rf-tight enclosure,   said rf-tight enclosure comprising an opening to allow a wave guide tube to pass therethrough and communicate with said channel,.].   said panel comprising at least one pair of holes, the holes positioned to communicate with said channel at one end thereof and to open said channel at an opposite end thereof adjacent said high frequency or low frequency transducer.   
     
     
       2. The .[.combination.]. .Iadd.system .Iaddend.of claim 1, comprising a pair of hollow channels extending into said panel, .Iadd.said at least one pair of transducers comprising .Iaddend.a pair of high frequency transducers and a pair of low frequency transducers mounted upon said panel,   .Iadd.said at least one pair of holes comprising .Iaddend.two pairs of holes positioned in said panel, with a hole of each said pair positioned in said panel to communicate at one end thereof with one of said channels, and at an opposite end thereof, to open a respective channel adjacent a respective high frequency or low frequency transducer.   
     
     
       3. The .[.combination.]. .Iadd.system .Iaddend.of claim 2, .[.wherein.]. .Iadd.further comprising an rf-tight enclosure, and .Iaddend. said rf-tight enclosure .[.comprises.]. .Iadd.comprising .Iaddend.a pair of openings to allow wave guide tubes to pass therethrough and to communicate with said channels.   
     
     
       4. .[.The combination of claim 1, additionally comprising.]. .Iadd.A sound system constructed entirely of magnetically inert rf-shielded components which remain unaffected by magnetic fields and do not affect imaging quality, said system comprising a magnetically inert panel,   at least one magnetically-inert transducer mounted upon said panel,   at least one hollow channel extending into said panel from an edge thereof,   an rf-tight enclosure in which said panel is mounted,   said rf-tight enclosure comprising at least one opening which is effective for enabling a wave guide tube to pass therethrough and communicate with said channel, and .Iaddend.   wave guide tubing made of an electrically conductive non-ferrous material mounted in said opening and extending into and out of said enclosure.   
     
     
       5. The combination of claim 3, .[.additionally.]. comprising a pair of wave guide tubes, each said tube mounted in a respective .[.opening.]. .Iadd.one of said openings .Iaddend.of said enclosure and extending into and out of said enclosure. .Iadd. 
     
     
       6.  A sound system constructed entirely of magnetically inert components which remain unaffected by magnetic fields and do not affect imaging quality, said system comprising a magnetically inert panel,   at least one magnetically-inert transducer mounted upon said panel,   at least one hollow channel extending into said panel from an edge thereof,   a hole positioned in said panel to communicate at one end thereof with said channel and at an opposite end thereof to open adjacent said at least one transducer,   a penetration panel located at a first room in which the magnetically inert panel and an MRI scanner are located; and   an electrical cable leading from the penetration panel to the magnetically inert panel. .Iaddend. .Iadd.7. The system of claim 1, further comprising a penetration panel at a first room in which the magnetically inert panel and an MRI scanner are located; and   an electrical cable leading from the penetration panel to the magnetically inert panel. .Iaddend. .Iadd.8. The system of claim 4, further comprising a penetration panel at a first room in which the magnetically inert panel and an MRI scanner are located; and   an electrical cable leading from the penetration panel to the magnetically   
     
     
        inert panel. .Iaddend. .Iadd.9.  The system of claim 6, further comprising: acoustic headset means for communicating sound into the ears of a patient; and   pneumatic tubing disposed between and connecting the acoustic headset means   
     
     
        and the magnetically inert panel. .Iaddend. .Iadd.10.  The system of claim 7, further comprising: acoustic headset means for communicating sound into the ears of a patient; and   pneumatic tubing disposed between and connecting the acoustic headset means and the magnetically inert panel. .Iaddend. .Iadd.11. The system of claim 8, further comprising:   acoustic headset means for communicating sound into the ears of a patient; and   pneumatic tubing disposed between and connecting the acoustic headset means   
     
     
        and the magnetically inert panel. .Iaddend. .Iadd.12.  The system of claim 9, wherein the pneumatic tubing is shorter than 25 feet. .Iaddend. .Iadd.13. The system of claim 10, wherein the pneumatic tubing is shorter than 25 feet. .Iaddend. .Iadd.14. The system of claim 11, wherein the pneumatic tubing is shorter than 25 feet. .Iaddend.
