  • Patent number: 4873465
    Abstract: The piezoelectric resonator (1) comprises two plates (5,6) and at least two parallel bars (2 to 4) connecting the plates (5,6) to each other. The orientation of the quartz wafer in which the resonator (1) is cut and the arrangement of the electrodes (9 to 11, 15 to 17) on the bars (2 to 4) are such that these bars (2 to 4) vibrate in an elongation mode. The elongation mode of the bars is coupled to a plate and bar flexure mode to improve the thermal properties of the resonator. This resonator can be used in devices in which the dimensions of the resonator have to be as small as possible and/or in which its resonance frequency has to be as low as possible.
