摘要： Elliptical vibrations are generated by combining longitudinal primary resonance vibrations resulting from expansion and contraction of a vibrator in a direction of a central axis and torsional secondary resonance vibrations or torsional tertiary resonance vibrations resulting from twisting of the vibrator around the central axis. A dimension ratio of a rectangle of the vibrator is set such that a resonance frequency of the longitudinal primary resonance vibrations and a resonance frequency of the torsional secondary resonance vibrations or the torsional tertiary resonance vibrations almost match. The vibrator includes a plurality of piezoelectric sheets. The longitudinal primary resonance vibrations and the torsional secondary resonance vibrations or the torsional tertiary resonance vibrations are generated because of formation of activation regions by polarization in a thickness direction of the piezoelectric sheets.

摘要翻译： 椭圆振动是通过将振动器的膨胀和收缩在中心轴线的方向上产生的纵向主共振振动和由振动器围绕中心轴线的扭转引起的扭转二次共振振动或扭转三次共振振动相结合产生的。 设定振子的矩形的尺寸比，使得纵向主共振振动的共振频率和扭转二次共振振动的共振频率或扭转三次谐振振动几乎相符。 振动器包括多个压电片。 由于通过在压电片的厚度方向上的极化而形成激活区域，所以产生纵向初级共振振动和扭转二次共振振动或扭转三次共振振动。

The vibrator includes, stacked in a short side direction of the cross-section, at least one torsional piezoelectric body that generates the torsional secondary resonance vibration or the torsional tertiary resonance vibration, and a piezoelectric body for longitudinal vibration that generates at least the longitudinal primary resonance vibration.
