PROBLEM TO BE SOLVED: To provide a vibrator capable of controlling noise occurrence without decrease of the discharged amount of a gas, a jet generator mounted with the vibrator and electronic equipment mounted with the jet generator. SOLUTION: The vibrator 15 has a frame 4, an actuator 5 mounted on the frame 4 and serving as a driving mechanism and a vibrating plate 3 supported on the frame 4 with an elastic supporting member 6. Two or more nozzles 2a and 2b are arranged on the front surface 1a of an enclosure 1. Air is discharged through the nozzles 2a and 2b in the form of a pulsating flow as the vibrating plate 3 vibrates. The actuator 5 consists of e.g., a voice coil motor, and the voice coil body and a magnetic circuit member, e.g., a magnet, are driven so as not to contact with each other. The arrangement can control noise occurrence while keeping a desired amount of a gas discharged. COPYRIGHT: (C)2007,JPO&INPIT
