Abstract

Perfeccionamientos en la estructura de aparatos reproductores de sonido con alimentación autónoma, destinados a ser llevados por encima de la altura de la cabeza y que comprende al menos un altavoz, un amplificador de audio-frecuencia, un juego de baterías y un alojamiento que rodea el amplificador de audio y el juego de baterías, cuyo eje longitudinal es aproximadamente perpendicular al eje del altavoz, caracterizados por el hecho de que la caja está desarrollada como un alojamiento a modo de barra hueca, similar a un asta de bandera, con un diámetro que queda esencialmente por debajo de la dimensión de profundidad del altavoz, y por el hecho de que este último se halla fijado en un extremo de la caja barra, exteriormente al contorno de la misma.
