High power ultrasonic transducer with broadband frequency characteristics at all overtones and harmonics

摘要: A transducer assembly for receiving a stimulating signal and producing ultrasound therefrom at one or more frequencies, over an ultrabroad bandwidth each frequency, includes front mass disposed about central axis, back the laterally offset from mass. The also resonators axis between mass, including least electrical contact signal. consists of low-density material, such as aluminum, aluminum alloy, magnesium, magnesium any various materials known in art. In general, is characterized by density less than 6.0 g/cc. embodiment, are made different materials, deviation symmetrical symmetry.
