Abstract
Las modalidades de esta solicitud se refieren al campo de las tecnologías electrónicas y de comunicaciones, y proporcionan un circuito de multiplexación, un sistema de circuito de interfaz y una terminal móvil, para resolver el problema de que una corriente de carga disminuye significativamente cuando un set de auriculares-micrófono se utiliza durante la carga de la terminal móvil, en comparación con un caso en el que la terminal móvil se carga de forma independiente. En un circuito de multiplexación, un primer circuito de conmutación transmite una señal de audio de canal derecho en un extremo de transmisión de canal derecho a un primer extremo de transmisión externa; un segundo circuito de conmutación transmite una señal de audio de canal izquierdo en un extremo de transmisión de canal izquierdo a un segundo extremo de transmisión externa; cuando se recibe un segundo voltaje de activación, pero no se recibe un primer voltaje de activación, un circuito de aislamiento transmite el segundo voltaje de activación a un tercer circuito de conmutación; y cuando se reciben el primer voltaje de activación y el segundo voltaje de activación, el circuito de aislamiento baja el tercer circuito de conmutación, y aísla un extremo de tierra de un segundo extremo de voltaje de activación; y el tercer circuito de conmutación controla la conexión entre el primer extremo de transmisión externa y un primer extremo de transmisión interna, y controla la conexión entre el segundo extremo de transmisión externa y un segundo extremo de transmisión interna.
