Abstract
An electronic system includes an air vent, a heat sink, a fan, and an acoustic filter. The acoustic filter is disposed between the air vent and the heat sink and includes a sound-receiving opening, a sound-emitting opening, an expansion chamber, a neck channel, and a resonant chamber. The neck channel includes a first opening and a second opening whose surface is perpendicular to the surface of the sound-receiving opening. The first opening is in communication with the expansion chamber. The resonant chamber is connected to the second opening. Fan noise that enters the resonant chamber via the neck tube is dampened by reflective acoustic waves generated by the resonant chamber.
