ABSTRACT:
A dual-speaker unit providing improved stereo base response and directionality for portable computer applications is disclosed. The small speakers direct low end frequencies into a mixing chamber which directs these frequencies out through a central exit port, thereby providing clearer base response without sacrificing psychoacoustic directionality.
The speakers are mounted on the mixing chamber and also rotatable relative to it, for adjustable stereo imaging and compact portability.
