Abstract

The invention provides a vibrating fan which comprises a base, an electromagnetic-type actuator and a fan blade. The electromagnetic-type actuator is arranged on the base and comprises a movable magnetic element and a fixed magnetic element, the movable magnetic element can be in reciprocating motion relatively to the fixed magnetic element, and the fan blade is connected to the movable magnetic element. Reciprocating motion of the movable magnetic element is utilized to drive the fan blade to vibrate so as to disturb air flow, so that heat-dissipating effect is achieved.

Description

technical field [0001] The present invention relates to a fan, in particular to a vibrating fan. Background technique [0002] In recent years, in order to facilitate the portability of portable devices, these portable devices are developing towards light, thin, short, and small, and the demand for heat dissipation is also relatively increased. Therefore, the heat dissipation technology of electronic products has become one of the focuses in related industries. [0003] Generally speaking, a portable device uses a centrifugal fan as a cooling fan, which uses the blades of the fan to rotate in the flow channel, pressurizes through the flow channel, and pushes the wind to the air outlet, so that the air can be dissipated by heat convection. Thermal energy dissipates to the external environment. [0004] However, although the rotation of the blades of the centrifugal fan can effectively push the airflow to remove heat energy, it often causes annoying wind field noise. In add...
