Abstract
An armature for an electromagnetic vibration generator is suspended at its periphery by a plurality of circumferentially spaced flexure members each connected to the vibrator stator by means of an anchoring bracket having a floating part connected to the outer end of the flexure member and a stationary part connected to the stator. The brackets are provided with recesses in each of which is located a resilient member of elongate form. The recesses have closed ends so as to reduce the tendency of the material of the resilient members to migrate during operation of the vibration generator as well as to provide rotational stiffness for the complete armature suspension assembly.
