Omnidirectional dispersion system for multiway loudspeakers |
| abstract |
A sound dispersing system using two or more vertically facing drivers in substantially coaxial alignment on a vertical axis. The drivers face conic reflectors which reflect sound radially over 360 degrees with substantial dispersion in vertical planes that include the vertical axis. Mounting means for drivers and reflectors are spaced vertically apart so that the vertical separation of the effective acoustic centers does not exceed industry standards for coherent sound above and below the horizontal plane equidistant between two drivers assigned adjacent bands of sound frequencies. The spacial relationship of the drivers and their mounting means cooperates with the slope of the reflectors insuring that sound energy is reflected directly into ambient air without reflection back upon driver diaphragms without encoutering obstructions in the soundpath from drivers to ambient air, without high frequency energy loss due to internal reflections and without high frequency standing wave activity between interior parallel surfaces. The dispersion system features means for adjusting time and phase alignment of the drivers in order to compensate for time and phase characteristics of different drivers and crossover networks. The dispersion system can exist as an independent structural unit which can be adapted to otherwise conventional loudspeaker systems as an inexpensive way of adding the enhancements of point-source omnidirectional sound to existing systems for enhancing non-directional frequencies. |
