Abstract: The present invention relates to a mobile terminal, an audio output device and an audio output system comprising the same. The mobile terminal according to an embodiment of the present invention comprises: a memory for storing audio data; a communication unit for receiving a repetitive radio signal from the audio output device; and a control unit controlling the audio data such that the audio data is transmitted to the audio output device in a wireless manner when the strength or the level of the repetitive radio signal is a first predetermined value or more, while reproducing the audio data, wherein the communication unit comprises a first communication module for receiving the repetitive radio signal and a second communication module for outputting the audio data to the audio output device. Therefore, the audio output device can output a sound of the audio data reproduced by the mobile terminal.
