Abstract
A speaker horn is adapted for coupling to a speaker drive assembly and for dispersing incident sound energy in a 360.degree. radial pattern. The horn includes two sound-dispersing structures for making a passageway generally symmetrical about a longitudinal axis. An inserted structure restricts the movement of the incident energy in one axial direction and includes a plug which is nested in close proximity to a wall of a receiving structure at the input end of the receiving structure. The receiving structure restricts the propagation of the sound energy in the other axial direction to cooperate with the inserted structure in defining the passageway in a radial pattern between the two structures. The plug includes a concave face perpendicular to the longitudinal axis for receiving incident energy. The plug, in cooperation with the inner walls of the receiving structure, effects a change in phase of sound energy encountering the plug, and acts as an intensity amplifier for incident sound energy. The two structures cooperate to define a substantially radially uniform, substantially expanding passageway for the sound energy through the horn.
