Abstract:
1. An acoustical fluid control mechanism comprising: a resonance chamber defining a cavity and having a port with the cavity sealed from the ambient but for said port for enabling oscillatory flow of a working fluid into and out of the cavity upon exposure of said resonance chamber to an acoustic signal containing a tone at a frequency that is substantially similar to a particular resonance frequency of said resonance chamber; and a rectifier for introducing directional bias to the oscillatory flow of the working fluid through said port, said rectifier having an inlet connected to said port of said resonance chamber for receiving the oscillatory flow of the working fluid from said port and an outlet for transmitting the directional flow of the working fluid away from said cavity, wherein said outlet is in fluid communication with said port of said resonance chamber at least during transmission of the directional flow of the working fluid therethrough.
