A micro damper device comprising a main body, a cover, a sensor component and a control component is provided. The main body has a first surface, a second surface, a convex and a coil. A current is introduced to the coil to form a magnetic field with a first and a second magnetic pole. The cover has a first end, a second end and a first magnetic component. The sensor component is disposed on a side opposite the convex to measure a first vibration direction of the second surface. The control component is electrically connected between the sensor component and the coil and controls the current for adjusting the polarity and the strength of the first magnetic pole for producing a force between the first magnetic pole and a third magnetic pole, which makes the main body move along a second vibration direction opposite the first vibration direction.
