VIBRATING PLATE, VIBRATOR, GENERATOR AND ELECTRONIC DEVICE Russian patent published in 2012 - IPC H03H9/19 

FIELD: electricity.

SUBSTANCE: vibrating plate is proposed, in which the outer shape is formed by etching of a plate Z, cut at the specified angles relative to mutually orthogonal axes X, Y and Z, being crystalline axes of the crystal, comprising the following: a base having a groove and a vibrating console stretching from the base; at the same time the groove comprises a recess in a positive direction of the axis X, formed by cutting the base from the side of the negative direction of the axis X to the side of the positive direction of the axis X, besides, the width in direction of the axis Y of the groove in the positive direction of the axis X achieves maximum at the end from the side of the negative direction of the axis X of the groove in the positive direction of the axis X, at the same time the base has such a shape that the width of the groove in the positive direction of the axis X gradually reduces from the end at the side of the negative direction of the axis X to the side of the positive direction of the axis X.

EFFECT: increased strength of a plate made by etching.
