Abstract
A vibrating mechanism section comprises an oscillator comprising a vibration coil, a movable iron piece, a stator iron core, a movable shaft, a return spring and so on; a vibration diaphragm driven by the oscillator; and an air pressure generating chamber in which a pulsating air pressure is produced by the vibration diaphragm. The oscillator is provided with a temperature sensor. A vibration isolating mechanism section comprises an insulator; a fluid chamber comprising a main chamber, a sub-chamber, a first orifice and so on; and an amplifying mechanism section comprising a balancing chamber into which the pulsating air pressure is introduced so as to cause the fluid in the main chamber to vibrate, a second diaphragm, a third fluid chamber, a second orifice and so on.
