ABSTRACT:
A portable sound unit is shown having a central case and one or more speakers. Each speaker has tongue rails around a portion of its circumference. The central case includes an openable lid permitting access to sound equipment contained within the central case. The central case has openings at either end when the lid is closed and grooves inside a portion of the central case near each opening. The grooves receive the tongue rails on the speaker when the lid is open. Upon positioning a speaker in the grooves in the central body, the lid may be closed, thereby securing the speakers to the central case. When the speakers are separated from the central case and electronically coupled to the sound equipment, the opened lid may serve as a lectern.
