Abstract
The present invention provides a small, quiet sonic cleaner which can be used to clean jewelry and other small objects. The cleaner includes a tank which is rigidly connected to a vibration generator such as an eccentrically loaded motor, and which is flexibly coupled to a base upon which the cleaner sits. The coupling of the tank to the base is preferably through progressive motion attenuators such as springs, which provide superior vibration isolation for the tank.
