摘要 |
A vibrating device includes a vibrator having multiple electromechanical energy converting elements, with the vibrating device generating a first standing wave and a second standing wave in the vibrator with a predetermined time phase difference. The first standing wave and the second standing wave having multiple nodal lines aligned in the same direction and being different in terms of an order. A first electromechanical energy converting element is disposed at a first portion, and a second electromechanical energy converting element is disposed at a second portion. The first portion extends in a first direction parallel to one of the multiple nodal lines, and the second portion extends in a second direction which crosses the first direction. |
