A high frequency transducer having a dome diaphragm with a configuration of a bisected ellipse to overcome the distortion and breaking point of prior art even domes at frequencies above 30 kHz. The dome diaphragm having an annular skirt extending therefrom in an integral fashion and connecting to a disc shaped plate of the transducer. A voice coil of cylindrical section being directly connected to the skirt at a region of close proximity to said dome. The dome being constructed of a rigid material such as a metal, an alloy, a metalloid such as, but not limited to, titanium, aluminum, and boron, or a combination thereof. The dome being constructed in accordance with a general formula for an ellipse (x<2>/a<2>)+(y<2>/b<2>)=1, and a>b. Wherein a is half of the distance of major axis and b is half of the distance of a minor axis.
