ABSTRACT:
An acoustical assembly and methodology for mounting audio speakers 28 in automotive vehicles an acoustical speaker (28) for generating sound waves including a pair of acoustical horns for directing sound in opposite directions from speakers (28) disposed at the center of the roof (12) toward the adjacent edge of the roof (12). The horns define a box-like central section (32) which is generally square in cross section and enclosing the the speakers (28). A tapered section (34) decreases in thickness from the central section (32) laterally in opposite directions to a rectangular cross section. A rectangular exit opening (38) faces generally transversely to the tapered section (34) and an exit section (36) interconnects the tapered section (34) and the exit opening (38) and the exit section (36) extends through a bend to direct the sound from the lateral direction of the tapered section (34) through the bend to a direction transversely to the tapered section (34) and generally at the window. The invention, therefore, includes a method comprising creating sound waves centrally of the roof (12) adjacent one of the edges, conveying the sound waves transversely of the vehicle in opposite directions from the center of the vehicle, and turning the sound waves through a bend and toward the adjacent window just below one of edges.
