<p>An audio signal transferring device includes an input interface and a USB (Universal Serial Bus) output interface; the device also includes: a boosting unit, a rectifying unit, and a filtering unit; in which, the input interface comprises a first audio signal input pin, which is used for receiving an audio signal sent by an audio signal transmit device connected with the pin, and outputting the audio signal to an input end of the boosting unit; the boosting unit is used for boosting the audio signal input from its input end, and outputting the boosted audio signal through its output end to an input end of the rectifying unit; the rectifying unit is used for rectifying the boosted audio signal input from its output end, and outputting the level obtained from the rectify through its output end to an input end of the filtering unit; and the filtering unit is used for filtering the level input from its input end, and outputting the direct current level obtained from the filtration through its output end to a VBUS (Voltage Bus) pin of the USB output interface.</p> |
