Abstract

ALTO-FALANTE. A presente invenção refere-se a um alto-falante que compreende um guia de onda de trompa tendo uma superfície de guia de onda, e um transdutor localizado em, uu adjacente a, uma garganta do guia de onda de trompa. O transdutor tem uma superfície acusticamente irradiando em formato de cúpula convexa, substancialmente rígida. Um ângulo de trompa, subtendido entre um eixo longitudinal do guia de onda de trompa e a superfície de guia de onda na garganta da trompa, está na faixa de 20 a 60 graus. Um ângulo de interseção, subtendido entre um plano tangencial ao formato de cúpula da superfície acusticamente irradiando e um plano tangencial à superfície de guia de onda em um ponto onde o formato de cúpula ou uma extrapolação do formato de cúpula encontra a superfície de guia de onda ou uma extrapolação da supeifície de guia de onda, está na faixa de 85 a 110 graus.
