Abstract
Amplificador de transistores adaptable a los combinados telefónicos de micrófono y auricular, caracterizado esencialmente por el hecho de estar constituído por una caja funcional autónoma, poco voluminosa en la que están alojados los elementos amplificadores que es capaz de sostener el combinado telefónico y en la que están alojados además un pabellón acústico de posición fija o variable en cualquier sentido, un circuito impreso alimentado por lo menos por una pila incorporada, de una fuerza motriz de pocos voltios, y un altavoz dispuesto según un ángulo especialmente estudiado con relación al pabellón acústico para evitar todo acoplamiento acústico con el micrófono.
