Abstract

Un altavoz que comprende un elemento acustico en forma de panel previsto para operar como un radiador de ondas de flexion y un transductor electrodinamico de bobina movil que tiene una bobina de audio montada al elemento acustico para excitar la vibracion de ondas de flexion en el elemento acustico, en donde la conexion entre la bobina de audio y el elemento acustico es de suficiente longitud en relacion al tamano del elemento acustico para representar una linea excitada tal que el elemento acustico tiene una impedancia mecanica que tiene una tendencia a ascender con la frecuencia de la onda de flexion.
