An acoustical fluid control mechanism and a method of controlling fluid flow of a working fluid with the acoustical fluid control mechanism are provided. The mechanism comprises a resonance chamber that defines a cavity. The resonance chamber has a port. The cavity is sealed from the ambient but for the port for enabling oscillatory flow of a working fluid into and out of the cavity upon exposure of the resonance chamber to an acoustic signal containing a tone at a frequency that is substantially similar to a particular resonance frequency of the resonance chamber. The mechanism further includes a rectifier for introducing directional bias to the oscillatory flow of the working fluid through the port. The rectifier has an inlet connected to the port and an outlet for transmitting the directional flow of the working fluid away from the cavity. The outlet is in fluid communication with the port of the resonance chamber at least during transmission of the directional flow of the working fluid therethrough.
