Abstract

An inertial vibration transducer (9) characterised by a plate-like piezo-electric bender (27) and means (20, 93) adapted to mount the bender on a member (2) to be vibrated, the arrangement being such that a substantial part of the bender is spaced from the member for movement relative thereto.
