Abstract

Un altoparlante que comprende un miembro acustico con forma de panel destinado a operar como irradiador de ondas de flexion y un transductor de bobina movil electrodinámico que tiene una bobina de voz montada en el miembro acustico para excitar una vibracion de ondas de flexion en el miembro acustico, donde la union entre la bobina de voz y el miembro acustico es de una longitud suficiente en relacion con el tamano del miembro acustico para representar un excitador de línea tal que el miembro acustico tenga una impedancia mecánica que tiene una tendencia ascendente con la frecuencia de las ondas de flexion.
