Abstract : An arrangement is disclosed for piezoelectric resonators utilizing linear and parallel sides or flats located on the periphery and opposite ends of the resonator. These sides are lcoated normal to the axes wherein collinear forces applied to the resonator produce a desired effect upon its natural resonant frequency. For technical sensor applications this aspect is maximized while for applications requiring a stable frequency or time base this effect is minimized. The outline peripheral shpae of the resonators utilizing this mounting arrangement varies in accordance with the crystallorgraphic orientation present in each resonator.
