The utility model belongs to the technical field of the electron, a smart -interactive terminal is provided. In the carrier roller device, including the wireless voice collector, the wireless receiving module, audio frequency processing module, audio amplification module, the smart -interactive terminal of control module and display playback module, in its work during in interactive mode, user output's local speech information is gathered through the wireless voice collector, and through the wireless receiving module, send to the distal end through control module a series of processing back ofaudio frequency processing module and audio amplification module, and the distal end audio signal that control module received carries out this locality broadcast with a series of processing back ofaudio amplification module through the display playback module through audio frequency processing module, when making user and smart -interactive terminal realization mutual, may not receive the restriction of spacing distance between the two, the problem of current smart -interactive terminal lead to at to a great extent limited subscriber rather than relative distance because of the defect thatremote multiple spot pickup effect is poor is solved.
