Abstract

Abstract An electrodynamical or electromagnetic oscillator comprising an electric oscillator including three transistors and a mechanical oscillator having an armature coil movable in a magnetic field. The transistors are turned ON in sequence to start current flow in the armature coil which is moved in the magnetic field in one direction to generate in the armature coil a counter voltage of positive polarity. This voltage varies the amount of current flow in the armature coil until the one directional movement of the armature coil is terminated whereat the transistors are turned OFF. Thereafter, the armature coil is moved in the magnetic field in the opposite direction to generate in the armature coil a voltage of negative polarity which voltage holds the transistors turned OFF
