Abstract

Altavoz de membrana de graves (1) - con una carcasa (10), cuyas paredes (13, 14, 15) de carcasa encierran un volumen (25) que está delimitado en el lado posterior de la membrana (3), - y con al menos una abertura (23) en una superficie de las paredes (13, 14, 15) de la carcasa, que delimita dicho volumen (25), caracterizado porque - el volumen (5) es tan pequeño que la frecuencia de resonancia del altavoz de membrana de graves, para la que el amplificador y la fuerza de recuperación de la membrana (3) actúan en el mismo sentido, se sitúa por encima de 200 Hz, especialmente por encima de 1000 Hz, encontrándose, por tanto, en la gama de frecuencias de un altavoz de tonos medios o de agudos, y - la abertura (23) está realizada para ser muy pequeña, de manera que para cada frecuencia del altavoz de membrana de graves el aire sale de dicho volumen a gran velocidad sin provocar interferencia acústica.
