振动装置及使用该振动装置的图像设备
摘要：
本发明提供振动装置及使用该振动装置的图像设备。振动装置具有：第1及第2压电元件，大致呈长方形状，具有施振部和非施振部；驱动它们的防尘过滤器驱动电路。第1及第2压电元件的重量平衡相对于假想对称轴和假想中心线彼此对称。第2压电部件相对于第2压电元件的振动中心轴的振动振幅的大小不对称。振动装置具有挠性体，其形成有第1、第2电路和连接端子，第1电路向第1压电元件输入电信号，第2电路在第1电路被输入电信号时，根据第1压电元件的振动，将在第2压电元件产生的电信号从第2压电元件输出，连接端子将第1和第2电路电连接。防尘过滤器驱动电路在第1和第2电路通过挠性体而连接的状态下，驱动第1和第2压电元件。
摘要（英）：

A vibrating device includes first and second members, each shaped almost like a rectangle and composed of first and second parts, a connection member composed of a first circuit which inputs an electrical signal to the first part, a second circuit which outputs an electrical signal generated in the second part, and a connection part which connects the first and second circuits electrically, and a drive unit which drives the first and second members while the first and second circuits remain connected by the connection part. The first and second members are shaped symmetrically to one another in weight balance with respect to a virtual symmetry axis at the same distance from the first and second members and also to an virtual centerline connecting gravity centers of the first and second members. The second member is shaped asymmetrically in vibrational amplitude with respect to its vibrational axis.
