Abstract

Un transductor (14) para producir una fuerza que excita a un radiador acustico, por ejemplo, un panel (12), para producir una salida acustica. Eltransductor (14) tiene una gama de frecuencia operativa prevista y comprende un elemento resonante que ti ene una distribucion de modos y que es modal en lagama de frecuencia operativa. Los parámetros del transductor (14) pueden ser ajustados para mejorar la modalidad del elemento resonante. Un altavoz (10) o unmicrofono puede incorporar dicho transducto r.
