  • High-fidelity electrodynamic line-source loudspeaker
    Patent number: 10506330
    Abstract: A loudspeaker system including a pair of elongated arrays of electrodynamic drivers, each array being composed of a plurality of drivers of the same type and size. The drivers are driven by electrical signals from an audio signal converter that receives an electrical audio signal representative of sound waves to be reproduced by the loudspeaker system and converts the electrical audio signal to a modified electrical audio signal by applying an inverse of the composite electromechanical bandpass transfer function and an inverse of the composite acoustical impedance high-pass transfer function to the electrical audio signal. The drivers may be circular drivers with a nominal size (diameter) of two to four inches.
