The indication module 5 also includes an LED lamp, which is connected with the processing module 3, and welded on the electronic circuit board 7 at a position aligned with the dial to illuminate the dial.

When the user rotates the knob 1 to input the station selection instruction, the knob 1 pulls the pull wire 53 to walk a certain track and drives the first pull wire wheel 61 to rotate. Then the first pull wire wheel 61 brings the rotation shaft 211 of the rotary potentiometer 21 to rotate, and the channel selection circuit generates an electrical signal corresponding to the channel selection instruction. The processing module 3 is linked to the network radio station through the communication module 4 in advance. When the processing module 3 receives the electrical signal, it obtains the audio resource corresponding to the electrical signal from the network radio station, and sends the audio resource to the content presentation unit. The content presentation unit receives and plays the audio resource. In such a way, the desired audio resource can be selected and listened by using the rotary tuning manner of the analog traditional radio. Meanwhile, the processing module 3 also drives the LED lamp to light up, then the lighted LED lamp can illuminate the dial to make the dial more obvious and easier to be observed by the user.

On the other hand, when the knob 1 is rotated for a certain angle, the pull wire 53 would bring the pointer 52 to move a certain distance along the dial. At this time, the pointer 52 is aligned with a certain scale value of the dial, so that the user can clearly know what kind of audio resources can be listened when the pointer 52 is aligned with the certain scale value on the dial. When the user wants to listen to the same audio resource next time, the user only needs to rotate the knob 1 so that the pointer 52 is aligned with the corresponding scale value. For example, when the pointer 52 is aligned with the scale value labeled “8” on the dial, the content presentation unit plays the audio resources of the humanities and social sciences class. Then, the next time when a user wants to listen to the audio resources of the humanities and social sciences class, he only needs to turn the knob 1 to enable the pointer 52 to align with the scale value labeled “8” on the dial.
