The vibrator unit has an oscillation coupling (43) coupled to the piezoelectric resonator (42), or to a point adjacent the latter, for mechanical vibration of a resonance element. An oscillation node is provided at the coupling point between the oscillation coupling and the piezoelectric resonator, the resonance frequency of the resonance element corresponding to the frequency of the transmitted oscillations. Pref. a number of different resonance elements (44, 50) exhibit differing resonance frequencies or oscillation modes. ADVANTAGE - Simple support of resonator without impairing oscillation characteristic. |
