摘要： An audio device and an audio input/output method are described, which is coupled to an audio port, and includes a capacitor, a load, an output amplifying module, and an input amplifying module. The capacitor and the load are coupled to the audio port. The output amplifying module is operated at a first working voltage, for outputting a first audio signal to the audio port. A direct current (DC) level of the first audio signal is substantially zero volts. The input amplifying module is operated at a second working voltage, in order to receive a second audio signal from the audio port. When the audio port is in an output state, the output amplifying module is enabled and the input amplifying module is disabled, and when the audio port is in an input state, the input amplifying module is enabled and the output amplifying module is disabled.
摘要翻译：描述了音频设备和音频输入/输出方法，其耦合到音频端口，并且包括电容器，负载，输出放大模块和输入放大模块。电容器和负载耦合到音频端口。输出放大模块以第一工作电压工作，用于将第一音频信号输出到音频端口。第一音频信号的直流（DC）电平基本为零伏特。输入放大模块以第二工作电压工作，以便从音频端口接收第二音频信号。当音频端口处于输出状态时，输出放大模块使能，输入放大模块被禁止，当音频端口处于输入状态时，输入放大模块使能，输出放大模块被禁止。
