Abstract
A vibrating device of thickness made of a piezo-electric material that has an electromechanical coefficient of coupling K greater than 0.15 and configured in the form of a discoidal body on whose end faces excitation electrodes are provided, characterized in that the largest dimension D of the areas 0 of the electrodes facing each other in the thickness direction of the vibrator satisfies the relationship (see formula), where d is the thickness of the discoidal body, K is the electromechanical coupling coefficient and A is a constant that, for the various vibration modes, has the following values: - for the thickness shear mode and for the thickness torsion mode, **(See formula)** - for the thickness compression or extension mode, **(See formula)** - for the thickness radial shear mode, **(See formula)** and because the distance of each point on the circumference of this area 0 from the vibrator edge is at least equal to the dimension of area 0 in the direction in which said distance is measured.
