Abstract

The piezoelectric resonator (21) includes a first and a second planar tuning fork shaped part arranged in a common plane. It is intended to be mounted on a support via a linking part (29), the linking part being arranged to connect the tips of the inner vibrating arms (25a, 25b) of the first and second tuning fork shaped parts so as to link the first and second tuning fork shaped parts together, The electrodes carried by the first and second tuning fork shaped parts are interconnected through the linking part so as to make the outer vibrating arms of the first and second tuning fork shaped part oscillate with opposite phase.
