Abstract
The present disclosure relates to a heat sink assembly and control method, and an electronic device and manufacturing method. The heat sink assembly includes: a vibrating plate including a magnetic material; a vibrating film, one end of which is connected with the vibrating plate; a driving device having an electromagnet, which is arranged opposite to the vibrating plate; a control circuit which is connected with the driving device and is configured for transmitting to the driving device a control signal for controlling the electromagnet to be energized and de-energized. The electromagnet generates a magnetic field that drives the vibrating plate to vibrate when the electromagnet is alternately switched between an energized state and a de-energized state. The vibrating film vibrates with the vibration of the vibrating plate.
