Abstract

PURPOSE: To improve the sensitivity by providing the mechanical resonance vibration system which is formed by combining an elastic body and weights together and has specific mechanical resonance characteristics above and/or below a piezoelectric body element.
CONSTITUTION: The piezoelectaric body element 2 is fitted on a sensor base 1 and the weight 3, elastic body 4, and weight 5 are fitted thereupon in this order. For example, when a leaf spring is used as an elastic body 4, the position of a screw 7 is adjusted and the deformation quantity of the leaf spring is varied to vary the elastic coefficient. Therefore, the resonance frequency varies with the elastic coefficient (k), so the position of the screw 7 is adjusted to adjust the resonance frequency. Various materials such as a metallic material and a high polymer material can be utilized for the elastic body 4 and used selectively to obtain the specific elastic constant (k).
