Abstract
The present invention relates to a piezoelectric resonator having adherent or non-adherent electrodes, the piezoelectric crystal comprising a central portion and a peripheral portion forming a ring that surrounds the central portion and that is connected thereto by an intermediate portion in which a slot is formed, the peripheral portion being connected to the central portion by a single connection bridge constituted by a non-slotted portion of said intermediate portion that extends over a small fraction of the periphery of said intermediate portion. The central portion constitutes the active vibrating portion of the crystal and the peripheral portion is held in the box by fastening means disposed in such a manner as to be thermally as remote as possible from the single connection bridge. The secured portion and the bridge constitute means for suspending the crystal.
