摘要:
A jet generating device (10) includes a vibrating member (3) which vibrates gas, a driving unit (5) which drives the vibrating member (3), and a housing (1) which has a first opening (2) and a first chamber (11) connected to the first opening (2) and containing the gas. The housing (1) supports the vibrating member (3), and is such that, of sounds generated as a result of vibrating the vibrating member (3), the sound having a maximum noise level has a predetermined frequency. In addition, the housing (1) discharges the gas as pulsating gas through the first opening (2) as a result of driving the vibrating member (3).

A jet generator includes a casing containing a gas and having an opening, vibrators attached to the casing, and actuators for actuating the vibrators. The vibrators vibrate with the vibrational forces thereof being synthesized so as to attenuate each other, thereby vibrating the gas to eject a pulsating jet thereof through the opening.
