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). |
