发明名称 Electro-mechanical transducer resonator for generating mechanical bending vibrations
摘要 The resonator specified consists of two steel parts between which ceramic plates polarised in opposite directions with respect to one another are inserted. To prevent parasitic torsion vibrations from being excited, the two steel parts are offset with respect to one another.
