| Summary: | A vibrating device includes a vibration plate that vibrates at a harmonic of a contour vibration and on which plural vibration members to are disposed. Moreover, support members are provided having first ends connected to the vibration plate and second ends connected to a frame base that surrounds the vibration plate. Cavities extending in a direction that intersects a direction in which the support members extend are formed in the base with flexure-vibration members formed therebetween. Both ends of the flexure-vibration members are joined to the base to serve as stationary ends. Moreover, a length between ends of the flexure-vibration members and a connected portion where each of the flexure-vibration member is connected to the corresponding support members is λ/4, where λ is a wave length of a flexural vibration corresponding to a frequency of a natural vibration in the vibration plate. |
