Abstract
An acoustic diaphragm is disclosed having a plurality of acoustic elements supported by the diaphragm. In a preferred form, each element is coupled to a driver and extends radially at a uniform acute angle to a normal of the driver. In the preferred embodiment, a plural layer of the elements is arranged so that the direction of each element is out-of-phase relative to each other, preferably in the range of approximately ninety degree. An element is also supplemental to the conventional acoustic diaphragm. The improved acoustic diaphragm is used in electric acoustic and acoustic electric transducer systems having improved performance at wide frequency range.
