Abstract

Patente de Invenção: <B>''ALTO-FALANTE NA FORMA DE PAINEL"<D>. Processo de operação de um alto-falante ressonante na forma de painel, que compreende a disposição do painel de alto-falante próximo a uma divisa, de modo a ser acusticamente articulado com relação à divisa e com o plano do painel do alto-falente em um ângulo com relação à divisa. O processo pode compreender a movimentação do painel entre uma posição de descanso, na qual o painel está paralelo e adjacente à divisa, e uma posição de uso, na qual o painel está em um ângulo com relação à divisa. Um suporte de alto-falante ressonante na forma de painel compreende um meio que engata e retém o painel de alto-falante a ser sustentado, um meio adaptado para ser engatado e fixado a uma divisa, por exemplo, uma parede ou um teto, e um meio que conecta o respectivo alto-falante e o meio de engate de divisa, por meio do que o alto-falante é sustendado adjacente à divisa em um ângulo com relação ao mesmo, e de tal forma que o alto-falante seja articulado acusticamente com relação à divisa. A combinação de uma alto-falante ressonante na forma de painel e um suporte se dá da maneira descrita acima.
