摘要:
A system is provided for producing synthetic jets. The system comprises a first synthetic jet ejector equipped with a first diaphragm which operates at a first frequency f1, and a second synthetic jet ejector equipped with a second diaphragm which operates at a second frequency f2. The first and second synthetic jet ejectors are positioned with respect to each other such that the sound intensity of at least one of the first and second synthetic jet ejectors is reduced through destructive interference, wherein f1 and f2 are out-of-phase by φ degrees, and wherein 20≦φ≦60.
