Abstract

"ALTO-FALANTES". Um alto-falante que compreende um elemento acústico em forma de painel projetado para operação como um irradiador de onda de dobramento e um transdutor de bobina móvel eletrodinâmico, que tem uma bobina de voz montada ao elemento acústico para excitar a vibração de onda de dobramento no elemento acústico, no qual a junção entre a bobina de voz e o elemento acústico é de comprimento suficiente em relação à dimensão do elemento acústico para representar um acionamento linear tal que o elemento acústico tenha uma impedância mecânica que tem uma tendência crescente com freq³ência de onda de dobramento.
