Abstract
A noise suppression apparatus and a fan module using the same are provided. The noise suppression apparatus includes a resonator, a status indication unit, and a first thermoelectric component. The resonator is disposed on a sound transmission tube of a noise generation source, and includes a chamber and a clapboard disposed in the chamber. The status indication unit generates a control signal according to an operational status of the noise generation source. The first thermoelectric component is disposed in the resonator, and has a first terminal fixed on a sidewall of the chamber and a second terminal connected to the clapboard. The first thermoelectric component deforms in response to the control signal as the operational status of the noise generation source changes, so as to move the clapboard to change resonance volume of the resonator, and thus resonance frequency of the resonator approaches noise frequency of the noise generation source.
