Abstract

DISPOSITIVO DE ACIONAMENTO PARA VIBRADOR MARìTIMO ACúSTICO. A presente invenção refere-se a um vibrador marítimo que em uma modalidade particular inclui um invólucro externo modelado substancialmente de forma elíptica, um acionador tendo uma primeira e segunda extremidade, pelo menos uma mola externa conectada entre a primeira extremidade e a segunda extremidade do acionador, e pelo menos uma mola interna conectada entre a primeira extremidade e a segunda extremidade do acionador. Uma ou mais massas são fixadas à mola interna. Pelo menos um elemento de transmissão conecta a mola externa e o invólucro externo. As molas externa e interna e as massas fixadas à mola interna são selecionadas para gerar uma primeira frequência de ressonância e uma segunda ressonância dentro da faixa de frequências entre 1 Hz e 300 Hz.
