Abstract
Patente de Invenção:<B>"ALTO-FALANTES EM FORMA DE PAINEL"<D>. Um alto-falante compreende um elemento de painel (11, 21, 31, 41, 61, 71, 81, 91) como um irradiador acústico ressonante baseado em uma ação de onda de desvio e um acionador (12, 22, 32, 42, 62, 72, 82, 92) acoplado ao elemento de painel para causar ondas de desvio ali. O elemento de painel tem sua capacidade de massa e/ou de desvio do elemento de painel localmente alterada ou de outra forma diferente, particularmente localmente ao acionador como acoplado ao elemento de painel. Orifícios locais (16, 26, 36, 46), massa afixada (66) ou um material de amortecimento afixado (76) são efetivos para reduzir uma freq³ência alta devido a efeitos de tamborilada no acoplamento acionador (17, 37, 47, 67, 77, 87).
