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.

Abstract: An electronic system includes a system air outlet, a heat sink, a fan and an acoustic filter. The acoustic filter is disposed between the system air vent and the heat sink and includes a front duct, a back duct and a single expansion chamber. A sound-receiving opening of the front duct is in airtight connection with the heat sink, and the sound-emitting opening of the back duct is in airtight connection with the system air vent. The single expansion chamber is disposed between the front duct and the back duct, and is located between the sound-emitting opening of the front duct and the sound-receiving opening of the back duct. The cross-sectional area of the single expansion chamber is larger than the cross-sectional area of an air outlet of the fan for generating reflective acoustic waves having a cut-off frequency so as to cancel noise generated by the fan.
