Abstract

Improvements introduced in the object of the main Patent No. 247,968, "A transducer device" for use in a device for recording or scanning, by means of a common recorder or scanner member, a groove-shaped recording track in which two signals with different oscillation directions are recorded simultaneously , which comprises at least two parts that are joined without a coupling part, each of said parts being substantially sensitive to only one of the two directions of oscillation, characterized in that the parts consist of piezoelectric material in the form of small rods, parts in which the direction of the piezoelectrically active axis is perpendicular to the main surfaces of the rods provided with electrodes, parts that, located next to one another in the direction of their length, are mechanically connected to each other, being such the location of the main surfaces that the active axes of the parts that are sensitive to a They are rotated to a given angle, preferably 90º, with respect to the active axes of the parts which are sensitive to the other signal.
