  • Multiple waveguide coaxial ceiling loudspeaker
    Patent number: 7142680
    Abstract: A flush mountable ceiling speaker (10) with individual coaxial waveguides (20, 22) for both the lower and high-frequency transducers (11, 12). The lower frequency radiation is combined with the sonic energy radiated by the high-frequency transducer (12) and shaped by the high-frequency waveguide (20) to create a coherent, uniformly controlled coverage pattern. The loudspeaker (10) creates a well defined sound dispersion pattern over a relatively large bandwidth, resulting in increased vocal intelligibility and more accurate reproduction of music at relatively great distances from the loudspeaker, as is particularly useful in association with high ceiling installations.
