Abstract:
An electro-mechanical transduction apparatus comprising: a shell or beam structure having oppositely-disposed sides and orthogonally disposed first and second shell axes; a transduction drive means having moving ends; coupled to the shell and disposed for drive along said first shell axis; a mechanical load coupled at only one of said oppositely-disposed sides thereof, to the shell at a location along said second shell axis and at a position outside of said transducer shell; and means for exciting said transduction drive means to cause said shell, and said drive means, to move along the direction of said second axis for driving said load, said transduction drive means moving in the direction of said first axis to activate the shell, and to simultaneously move as an inertial reaction mass in the direction of said second axis.
