ABSTRACT:
Piezoelectric resonator with maximum sensitivity to external pressure stres.
The resonator includes means (2,3) for exerting nonlocalized radial compressive forces uniformly over diametrically opposed peripheral zones of the crystal (1) in which the zones occupy a predetermined sector 2.alpha. of at least approximately 110.degree. and are oriented so that the bisectors (A--A) of the peripheral zones form a predetermined angle .psi. with the crystallographic X axis of the crystal.
Depending on the value of .psi., it is possible to minimize or, on the contrary, maximize the sensitivity of the resonator to the external pressure stresses.
