ABSTRACT:
The piezoelectric resonator according to the invention includes a tuning fork shaped part with two parallel vibrating arms, connected to each other by a linking part, from which protrude a central arm located between both vibrating arms of the tuning fork shaped part, the vibrating arms carrying first electrodes to make them vibrate, these electrodes being connected to connection elements carried by the central arm, wherein a slot has been cut within the linking part opposite to the central arm and wherein second electrodes have been arranged along said slot.
