PROBLEM TO BE SOLVED: To provide an excellent acoustic diaphragm to be created by comprehending the lamination of elements of a human eardrum and the laminated structure of a wing, and by comprehending the natural theory thereof. SOLUTION: With respect to an acoustic diaphragm 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 perpendicular of the driver. In the preferred embodiment, the elements of plural layers are arranged so that the direction of each element is out-of-phase relative to each other, preferably in the range of approximately ninety degree. The 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 over a broadband. COPYRIGHT: (C)2006,JPO&NCIPI
