Abstract

As formas de realização do presente pedido estão relacionadas ao campo das tecnologias eletrônicas e de comunicação, e fornecem um circuito de multiplexação, um sistema de circuito de interface e um terminal móvel, para resolver um problema que uma corrente de carregamento diminui significativamente quando um fone de ouvido é usado durante o carregamento do terminal móvel, comparado com um caso em que o terminal móvel é carregado de forma independente. Em um circuito de multiplexação, um primeiro circuito de troca transmite um sinal de áudio do canal da direita em uma extremidade de transmissão do canal da direita para uma primeira extremidade externa de transmissão; Um segundo circuito de troca transmite um sinal de áudio do canal da esquerda em uma extremidade de transmissão do canal da esquerda para uma segunda extremidade externa de transmissão; Quando uma segunda tensão é recebida, mas a primeira tensão não é recebida, um circuito de isolamento transmite a segunda tensão para um terceiro circuito de troca; e quando a primeira tensão e a segunda tensão são recebidas, o circuito de isolamento puxa o terceiro circuito de troca e isola uma extremidade da base a partir de uma segunda extremidade em tensão; e o terceiro circuito de troca controla a conexão entre a primeira extremidade externa de transmissão e uma primeira extremidade interna de transmissão, e controla a conexão entre a segunda extremidade externa de transmissão e uma segunda extremidade interna de transmissão.
