Abstract
A vibration device is provided with reduced thickness and size while maintaining vibration strength. The vibration device includes a first elastic plate with first and second ends and a first planar section disposed between the first and second ends. Moreover, a second elastic plate is joined to the second end of the first elastic plate and includes a second planar section opposing the first planar section of the first elastic plate. The second elastic plate has a flexural rigidity that is higher than that of the first elastic plate. In addition, a piezoelectric vibrating element is disposed on in the first planar section of the first elastic plate to face the second elastic plate. A weight can be attached to the first end of the first elastic plate to facilitate vibration.
