Fan device

A Fan device comprising:

• a high voltage power source;
• a conductive blade, electrically connected to first electric contact of the high voltage power source, wherein the conductive blade includes a connection side and a vibration side, and the first electric contact is connected to the connection side, and the conductive blade is extended along a first direction between the connection side and the vibration side;
• a first electrode, electrically connected to second electric contact of the high voltage power source, wherein the first electrode is disposed beside the vibration side and located in vibration range of the vibration side;
• a resistance device, connected between the conductive blade and the second electric contact in series;
• and
• a frame, configured to fix the connection side of the conductive blade;
• wherein when the high voltage power source provides second electric charge to the first electrode via the resistance device, the vibration side of the conductive blade is being attracted by the first electrode until they touched;
• the vibration side bounces back after touching the first electrode due to electrical balance, the first electrode then resupplies the second electric charge from the high voltage power source to attract the vibration side, causing the vibration side waving back-and-forth.
