Abstract

A piezoelectric acceleration transducer has a piezoelectric element with a plane surface arranged in contact with a mass. The mass and the piezoelectric element are held in fixed relationship to each other by a support structure arranged in such a manner that inertia forces effective on said mass are directed to be effective perpendicularly on the plane surface of the piezoelectric element. A bearing point or line is provided between the mass and the support structure in such a position that the directional sensitivity of the transducer may be determined by said position.
