    摘要： A speaker diaphragm which includes a woven cloth which contains a thermosetting resin of thermo-cured state, and a paper board bonded and integrated with the woven cloth at the back surface. The woven cloth has its weave texture exposed on the front surface. The diaphragm has a high strength because it is made with a woven cloth; furthermore, its hardness is high because the thermosetting resin impregnated in woven cloth is in thermo-cured state. Thus the diaphragm helps implementing a speaker which demonstrates superior vibration characteristics in the high frequency sound region.

    摘要： 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.
