The transducer consists of a flat coil with a spring-loaded aluminium plate. Eddy currents force the plates to separate sharply, producing a low pressure region between the plates into which the water rushes generating a pressure wave by implosion."@en ; skos:narrower , , ; skos:notation "SDN:L05::BOMR" ; skos:note "accepted"@en ; skos:prefLabel "Boomer"@en .
