Abstract
A system and method are disclosed for using a sonic frequency to induce a vibration useful for clearing dust accumulation from microelectronics, such as a laptop computer. A speaker driver may be mounted onto a support structure for a heat exchanger (220). At an advantageous time, such as boot up, a sonic frequency may be driven onto the speaker (250), thus inducing vibration in the heat exchanger (220) and helping to clear dust accumulation. In some cases, a resonant frequency may be used to optimize the amount of vibration per unit power delivery.
