Abstract

Altavoz que comprende un elemento en forma resonante, en forma de panel, adaptado para producir una salida acústica y un sistema de excitador de vibraciones, sobre el elemento en forma de panel y adaptado para aplicarle una energía de onda de flexión, caracterizado porque el sistema de excitador de vibraciones está adaptado para aplicar un par flector, al elemento en forma de panel. El excitador de vibraciones del altavoz puede estar acoplado al elemento en forma de panel para difundir una pluralidad de líneas nodales en el elemento en forma de panel; y además puede comprender una suspensión (como espuma de plástico de alta resistencia al esfuerzo de empuje) sobre la que está montado el forma de panel, suspensión que actúa de modo de pivote en torno al cual puede articularse, por lo menos una parte de un borde del elemento en forma de panel adyacente al sistema excitador de vibraciones. Este sistema también puede comprender un motorelectrodinámico, provisto de un rotor, con un conjunto de conductores de corriente fijado al elemento en forma de panel, con su eje paralelo al plano del elemento, para aplicarle una torsión y un imán que conforma un campo magnético en el que esta situado el rotor. También se incluye un procedimiento para fabricar un altavoz según el descrito.
