Abstract

"UNIDADE DE ACIONAMENTO DE ALTO-FALANTE, E, SISTEMA PARA O REFORçO DE SOM PARA INSTALAçõES PúBLICAS". Uma unidade de acionamento de alto-falante composto compreendendo uma primeira unidade de acionamento e uma segunda unidade de acionamento dispostas de forma coaxial com relação ao eixo central do alto-falante, e cada unidade de acionamento compreendendo meios de imã permanente e meios de peça de pólo que juntos formam um circuito magnético com um espaço de pólo para excitar um conjunto de bobina móvel, cada espaço de pólo fornecendo um campo magnético direcionado radialmente com relação a um eixo central do alto-falante. Pelo menos um dos meios de imã permanente possui uma direção de magnetização de extensão radial com relação ao dito eixo central do alto-falante e os centros acústicos das ditas unidades de acionamento coincidem de forma substancial.
