VIBRATOR

摘要

A vibrator is proposed with an exhaust chamber in a baseplate thereof. The exhaust chamber is limited by walls of the baseplate, second bushing and the outer surface of a hollow elastic element and is in communication with an above-membrane chamber via a second duct. The elastic element is a truncated hollow cone, the smaller base of which firmly encompasses the second bushing, while the larger base bears against the baseplate. A first duct communicating the above-membrane chamber with the atmosphere is formed by radial ducts in the cover of the baseplate, in which an annular collector is made, communicating with said radial ducts. The flow area of each of the ducts is less than the flow area of the collector. The latter by means of coaxial axial ducts made in the cover and in the baseplate communicates with a second annular collector made in the baseplate and communicating with the atmosphere.
