That's fundamentally impossible, at least from the level of a software application (it could be possible in hardware or even firmware). That device works by taking advantage of the microphone jack included in the headphone jack. The hardware communicates with the application via an audio signal that is read from the microphone input.

这从根本上来说是不可能的，至少从软件应用程序的层面来看（这在硬件甚至固件中是可能的）。该设备通过利用耳机插孔中包含的麦克风插孔来工作。硬件通过从麦克风输入读取的音频信号与应用程序进行通信。
