Abstract

Patente de Invenção:<B>DISPOSITIVO ACúSTICO USANDO MODO DE ONDA DE FLEXãO RESSONANTE''<D>.Um dispositivo acústico, por exemplo um alto-falante, apresenta um transdutor (38), acoplado através de um membro altamente perfurado (36) a uma área acusticamente ativa (39), que pode ser em formato de película, sobre parte do membro altamente perfurado. O membro altamente perfurado (36) pode ser uma malha. Ondas em curvatura podem ser excitadas no membro altamente perfurado (36) através do transdutor (38) e o som emitido a partir da área acusticamente ativa (39).
