A single loudspeaker has a substantially single-point source of sound
energy derived from multiple drivers to provide a surround sound effect.
The surround sound is effective for listeners close to the single
loudspeaker or substantially distant within a room. The physical size of
the loudspeaker is convenient for placement on top of a computer monitor
or television set. The single loudspeaker produces a dynamically variable
energy gradient between the listener's right and left ears and the
perception of sound emanating from changing locations in the space
surrounding the loudspeaker. The placement of a plurality of these
loudspeakers surrounding the expected listener location allows the
coverage of larger spaces with separate dynamically variable energy
gradient pairs.
