Loudspeaker system for producing multiple sound images within a listening area from dual source locations

摘要

A loudspeaker system comprises two spaced-apart sound cabinets with the first cabinet housing a speaker driver directed toward a listener and couplable to a left channel signal to create a left channel sound image and a second speaker mounted in a second of the cabinets and couplable to a right channel to create a right channel sound image in a listening area. Third and fourth speaker drivers are positioned, one in each of the two sound cabinets, proximate to one of the first and second speaker drivers. The third and fourth drivers have axes which are angled with respect to the axes of the first and second drivers and are couplable to a signal having frequency components of center channels. The sound images created by the third and fourth drivers are focused inwardly in the listening area between the right and left channel sound images to create a focused center channel image in the listening area and thereby provide a listener with multiple-sound images generated from two sound cabinets for more realistic sound presentation.
