Abstract

"DISPOSITIVO DE CANCELAMENTO DE VIBRAçãO COMPACTO". A presente invenção se refere a um dispositivo de cancelamento de vibração aperfeiçoado designado para superar muitos dos problemas inerentes nos dispositivos anteriores. Em muitas concretizações, o dispositivo de cancelamento de vibração e menor em escala do que os desenhos anteriores, facilitando mais versatilidade em relação às opções de desenho. O dispositivo da presente invenção alcança um menor tamanho parcialmente devido ao uso de molas de suspensão tendo um afastamento preferivelmente do que um arranjo paralelo.
