Disclosed is an interactive device for an internet radio station including a content presentation unit and a content selection unit. The content selection unit includes an operation module, a processing module, an indication module and a communication module. The operation module is used by a user to input a channel selection command by means of manual rotation and to generate a corresponding electrical signal. The processing module is used for acquiring corresponding audio resources from the network radio according to the electrical signal and issuing the corresponding audio resources to the content presentation unit which is used for playing back the audio resource. The processing module is further used for driving the indication module to generate a state change corresponding to the electrical signal. Hence, the user may select audio resources by rotating the operation module, so that the channel selection is similar to a traditional rotary tuning method.
