ABSTRACT:
This invention relates to an oscillator having reduced sensitivity to acceleration. The oscillator includes a plurality of asymmetrically mounted resonator portions each having an active resonance region. The asymmetric mounting of the resonator portions means that each resonator portion has an axis passing through its active resonance region along which the acceleration sensitivity vector is dominant, i.e. the sensitivity to acceleration along the direction defined by one axis is much greater than the sensitivity to acceleration in other directions. The resonators are mounted in an oscillator such that their dominant axes are directed in different directions, e.g. an anti-parallel arrangement, which means that the dominant acceleration sensitivity vectors can cancel each other out.
