  • Patent number: 9102407
    Abstract: A resonance engine is disclosed including: a driver plate, to which is coupled at least one oscillatory transducer; a drive signal generator connected to the oscillatory transducer for excitation thereof; a first spring-mass resonator, having a first natural resonant frequency, with a proximal end attached to the driver plate and a free distal end; and a reaction means attached to the driver plate substantially opposite to the first spring-mass resonator. When the oscillatory transducer is excited by a drive signal from the generator having a component at or close to said natural resonant frequency, the first spring-mass resonator oscillates at resonance, substantially in anti-phase to the driver plate. Small vibrational strains in the oscillatory transducer are converted to large strains of controllable kinematic movements.
