High fidelity loudspeaker system for aurally simulating wide frequency range point source of sound

A high accuracy loudspeaker system for transducing an electrical signal containing frequencies located within a spectrum extending generally over the full range of audible frequencies into a sound field which closely approximates the sound field generated by a wide-frequency-range point source of sound, comprising:

• lower frequency reproducer means for reproducing and propagating a certain lower frequency region of said spectrum generally along a first axis;
• an ellipsoidal convex reflective dispersing means located on said axis spaced from said lower frequency reproducer means in the direction of sound propagation therefrom, to reflect and disperse acoustical energy from said lower frequency reproducer generally uniformly over a wide angle;
• a plurality of discrete higher frequency reproducer means for reproducing and propagating a certain higher frequency region of said spectrum, said higher frequency reproducers being mounted substantially equispaced over the surface of said ellipsoidal dispersing means and being so spatially oriented with respect to one another as to cause their axes of propagation to diverge generally uniformly away from a point near the center of said ellipsoidal dispersing means;
• means to permit commonly energizing each of said plurality of higher frequency reproducer means with a single higher frequency signal, and to permit energizing said lower frequency reproducer means with a lower frequency signal.
