Abstract

Patente de Invenção: <B>''APARELHO ACúSTICO EM FORMA DE PAINEL QUE UTILIZA MODOS DE ONDAS DE FAIXA''<D>. Trata-se de um membro acústico em forma de painel capaz de suportar vibração de onda de faixa dotado de uma velocidade de onda de faixa variada na região de coincidência para proporcionar uma faixa de freq³ências de coincidência, para fazer com que a conjugação acústica das ondas de faixa no painel ocorra sobre uma faixa ampla de ângulos ou para tornar a conjugação mais uniforme. O membro pode ser incorporado em um alto-falante dotado de um membro de painel (1) e um excitador (3) fixado ao membro de painel para excitar as ondas de faixa no alto-falante para promover uma saída acústica.
