摘要： The tuning fork resonator (1) includes a base (4) from which first and second parallel vibrating arms (2, 3) extend, carrying a set of excitation electrodes (5, 6) for vibrating the arms at a fundamental frequency. Grooves (7, 8) are formed on at least one of the top or bottom surfaces of each of said arms. The vibrating arms have a generally tapered shape, and are extended by an enlarged flipper shaped portion (9, 10) which forms the free end of each arm. The groove (7, 8) is extended in the direction of the free end of an arm to beyond the start of the flipper (9, 10) so as to increase said first motional capacitance of the resonator for the fundamental frequency, to decrease said second motional capacitance of the resonator for the partial frequency and to ensure better distribution of mechanical stress along the vibrating arms and to increase shock resistance.
