DescriptionElectric (magneto-acoustic) violin with slender, violin-shaped top mounted on a mahogany bar with outwardly curved lower side, and partial ribs and back at upper and lower ends only. Bridge fit in to slot in top, resting (over a wooden and dark-red plastic platform) on a paramagnetic metal bar-armature, the vibration of which varies the intensity of the magnetic field between two pole pieces (each attached to opposite polar ends of a U-shaped permanent magnet), inducing an electric current in a wire coil-winding surrounding one of the pole pieces. The ends of the wire coil-winding are connected to a variable resistance volume-control unit (with an adjusting knob), from which wires extend to the tip-jacks. The bar-armature is divided into two sections with unfriendly resonances using either a notch or a dividing block to prevent its own natural frequency vibrations from overwhelming other frequencies. Through differing divisions of the bar-armature, its total length, its thickness and width, and stiffness or elasticity, it is possible for the manufacturer to pre-determine the tonal qualities of the instrument. The electrical output of the magneto-acoustic unit is sufficient for use with headphones for practice, or it can be fed into an amplified loud-speaker
