振动装置
摘要：
本实用新型所涉及的振动装置具备压电元件、振动体。压电元件具有压电素体、一对第一电极。压电素体具有互相相对的第一主面以及第二主面。一对第一电极被配置于第一主面上。振动体具有金属板、绝缘层、一对第二电极。金属板具有互相相对的第三主面以及第四主面。绝缘层被配置于第三主面上。一对第二电极被配置于绝缘层上。压电元件和振动体以第一主面和第三主面经由绝缘层相对的形式被配置。一对第二电极物理性地接触于所对应的第一电极。一对第二电极从与第三主面正交的方向看从压电元件露出，并且与绝缘层的全部的边缘分离。根据本实用新型的振动装置，能够谋求到位移量的提高。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model relates to a vibration device possesses piezoelectric element, pendulum. Piezoelectric element has the plain body of piezoelectricity, a pair of first electrode. The plain body of piezoelectricity has relative first interarea and second interarea mutually. A pair of first electrode is disposed on first interarea. The pendulum has metal sheet, insulating layer, a pair of second electrode. The metal sheet has relative third interarea and fourth interarea mutually. The insulating layer is disposed on the third interarea. A pair of second electrode is disposed on the insulating layer. Piezoelectric element and pendulum are disposed via the form that the insulating layer is relative with first interarea and third interarea. Contact in the first electrode that corresponds to apair of second electrode physics nature. A pair of second electrode is seen from the direction with third interarea quadrature and is exposed from piezoelectric element to overall edge separation withthe insulating layer. According to the utility model discloses a vibration device, improvement that can the volume of seeking the displacement.
