Abstract
A piezoelectric stereo transducer device for the simultaneous conversion in electrical voltages of the signals recorded in a groove-shaped track, especially for use in the 45º -45º system, transducer comprising a piezoelectric element of the type particularly sensitive to bending forces while the main faces of the piezoelectric element located on the outside side are provided with electrodes, of which at least one is interrupted halfway in the direction that forms a right angle with the longitudinal element, while the halves of the element thus obtained are exposed to bending forces by the scanning needle, said transducer characterized by the fact that the flexure or curvature due to the vertical component of one of the directions of oscillation and the bending or curvature due to the horizontal component of the same direction of oscillation have equal meaning in one of the halves of the element and opposite senses in the other half, so that the charges produced by said bending forces on the electrodes are mutually amplified in one of the halves of the element and are sensibly neutralized in the other half, while the bending or curvature due to the vertical component of the other direction of oscillation and the bending or curvature due to the horizontal component of the same direction of oscillation have opposite senses in said first half of the element and the same sense in the other half mentioned, of so that the charges produced by said bending forces on the electrodes are substantially neutralized with respect to each other in said first half of the element and mutually amplified in said other half.
