Abstract
The micro-resonator comprises, cut from the same quartz crystal, a bar and a suspension frame means. The bar is cut in a substantially Z cut mode. The excitation electrodes are disposed on the sides of the bar. The length of the bar is substantially parallel to the Y axis. This produces a resonator which vibrates in a main mode of extension-compression, at from 0.5 MHz to 4 MHz.
