Abstract
Ultrasonic devices having transducer assembly including a stack of alternating electrodes and piezoelectric elements. A mounting device having a first and second end is adapted to receive ultrasonic vibration from the stack and transmit it from the first to the second end. A bolt including a head and shaft is configured to threadedly engaged the mounting device. The transducer assembly includes a deformable pressure element having a central opening that permits insertion of the shaft therethrough, and has a convex side facing the bolt head and a concave side facing the stack in a non-deformed state, but, in a deformed state, applies compression forces to the stack based on the deformation. The deformable pressure element may alternately include a surface area, in its deformed state, substantially equivalent to the surface area of a piezoelectric element and/or a first and second beveled surface defining the concave side.
