Abstract:

A sonic wave generator includes at least one pair of concave acoustic baffles arranged in concavely facing relationship in mutual coaxial alignment. The facing acoustic baffles of the pair are spaced apart from each other by a predetermined distance so that an annular opening is formed between the peripheral edges of the openings of the facing concave baffles. A driven diaphram is located at the closed end of each audio baffle opposite the open end of the baffle. The driven diaphrams located in the baffle pair face toward each other in mutual coaxial alignment and in coaxial alignment with the acoustic baffles.
