Abstract
By providing a spherically shaped housing or enclosure containing one or more drivers or speakers motors, and cooperatively mounting the housing in association with a uniquely constructed reflector, a spherical loudspeaker system is achieved which controls and shapes the ultimate acoustical waveform produced thereby. The loudspeaker system of the present invention controls and distributes the acoustical energy of the driver and housing, while shaping the acoustical energy field into a true hemispherical pattern, within the system's power bandwidth. By employing the present invention, the point of summation of the hemispherical pattern is approximately eight times the diameter of the reflector, thereby achieving the desired hemispherical polar coverage patterns.
