    • 【課題】圧電モーターの駆動特性に悪影響を与えることなく、振動体を支持する。 【解決手段】屈曲振動可能な振動体が接合された接合部と並設され、振動体および接合部を支持するための支持部を設けて、接合部および支持部を複数の連結部によって連結する。そして、支持部は、接合部よりも剛性を高くする。こうすれば、振動体で発生する振動(接合部で許容される振動)が支持部に伝わっても、剛性が高い支持部では、その振動が抑えられる(許容されない)。こうして支持部に意図しない共振が発生することを抑制すれば、振動体の本来の振動が邪魔されず、振動体の端部は特定の軌道で運動するので、対象物に対して所定の駆動力を伝えることができる。その結果、圧電モーターの駆動特性を維持しながら、対象物から受ける反力で振動体が動かないように振動体を支持することができる。 【選択図】図1
    • 要解决的问题:支持振动器而不影响压电电动机的驱动特性。解决方案:提供一种与能够弯曲振动并支撑振动器和接合部分的振动器的接合部分并列的支架,然后 接合部分和支撑件通过多个联接部分联接。 支撑体的刚性设定得高于接合部的刚度。 通过这样的配置,即使在振动器中产生的振动(在接合部可接受)向支撑体传递,在高刚性的支撑下抑制(不接受)振动。 由于原始振动不受阻碍,振动器的端部在特定的轨道上移动,所以当在支撑体中抑制非预期的共振的发生时,可以将预定的驱动力传递到物体。 结果,在保持压电电动机的驱动特性的同时,可以将振动器支撑成不会被物体的反作用。
