Description

FIELD OF THE INVENTION The present disclosure relates to a technical field of dampers, and particularly relates to a damper device and an electronic apparatus. BACKGROUND OF THE INVENTION During work, a micro motion mechanism (e.g., voice coil motor) would generate unnecessary motion after the micro motion mechanism undergoes external stimulation or external interference (e.g., shaking). In order to reduce the effect of the external interference which the micro motion mechanism undergoes, a damper may be disposed in the micro motion mechanism to lower the frequency response of the micro motion mechanism to the external interference. For example, the damper may include a damping pin and a gel. One end of the damping pin is fixed, and the other end of the damping pin may move in the gel along the radial direction of the damping pin. The damping pin moves in the gel and remains bonding to the gel to lower the frequency response of the micro motion mechanism to the external interference. The shape of the common damping pin is a long rectangular parallelepiped or a cylinder. When the damping pin moves in the gel, the torque rotating the bottom of the damping pin is generated. Under the interaction of the torque, the damping pin squeezes the gel so that the gel is deformed. After the damping pin moves in the gel many times, a gap is generated between the damping pin and the gel. Because of the gap between the damping pin and the gel, the contact area of the damping pin and the gel would be reduced so that the bonding force between the damping pin and the gel is reduced and the damping pin is easily detached from the gel. Hence, the existing damping pin has a problem that the bonding force between the damping pin and the gel is reduced and the damping pin is easily detached from the gel after the damping pin moves in the gel many times. SUMMARY OF THE INVENTION The object of the present disclosure is to provide a damper device which has an advantage that the first damper component is not easily detached from the first gel because the bonding force between the first damper component and the first gel is reduced.
