<p>An audio signal adapter device comprising: an input port, an output port, a boost converter unit, a rectifier unit, and a filter unit. The input port comprises an audio pin used for receiving an audio signal and for outputting to the boost converter unit the audio signal received. The boost converter unit is used for boosting the audio signal inputted and for outputting to the rectifier unit the audio signal boosted. The rectifier unit is used for rectifying the audio signal boosted, and for outputting to an input end of the filter unit a level acquired via the rectification. The filter unit is used for filtering the level inputted, and for outputting to a power pin of the output port a direct current level acquired via the filtration. The output port also comprise an audio signal pin, which is connected to the audio pin of the input port or to an output end of the boost converter unit, a reference signal pin, and a ground pin connected thereto.</p> |
