Abstract : The patent describes a transducer pressure release system wherein the transducer element is supported between a radiating and a load mass, both of which are resiliently supported in a watertight housing. A pair of magnetic coacting coils, one of which is affixed to said housing and the other to one of the masses, are supplied current through a control means from a constant voltage source. The control means receives an input signal from a displacement sensor which detects the movement of one of the masses and fixes a current through the coils to restore the masses to a constant separation therebetween, thus providing isolation and proper pressure release.
