Abstract

Patente de Invenção: <B>"DISPOSITIVO ACúSTICO QUE COMPREENDE UM MEMBRO DE PAINEL CONFIANDO SOBRE A AçãO FLETORA DE ONDAS"<D>. Dispositivos acústicos confiam sobre a ação fletora de ondas em um membro de painel, particularmente distribuição de modos ressonantes da dita ação de onda fletora e vibração superficial acusticamente significativa correlata sobre a área do membro de painel favorável ao desempenho do dispositivo acústico desejado ou pelo menos aceitável. Os dispositivos agem de acordo com a seleção de parâmetros do membro de painel afetando a distribuição, inclusive configuração/geometria e/ou rigidez à flexão, e/ou locações de transdutores de onda fletora na dita área do membro de painel, a seleção sendo de acordo com a avaliação analítica de características relacionadas com a transferência de potência do membro de painel assim o dispositivo acústico em causa e desideratos para o mesmo correlacionados com a obtenção de desempenho do dispositivo acústico.
