PURPOSE: To provide a small-sized device capable of obtaining excellent output characteristics in bodily sensation vibration and a buzzer sound also by supporting one end of a piezoelectric diaphragm to a frame, making the other end of the piezoelectric diaphragm 2 a free end and attaching a weight 3 to the free end.

CONSTITUTION: By supporting only one end of the piezoelectric diaphragm 2 to the frame 1, and attaching the weight 3 to the free end of the piezoelectric diaphragm 2, the device is miniaturized as the whole, and is thinned especially. That is, since this piezoelectric vibration pronouncing device makes a base, the piezoelectric diaphragm 2 and the weight 3 the subjects, the whole is thinned and miniaturized. Then, when the bodily sensation vibration of a low frequency is generated, the weight 3 of the free end side of the piezoelectric diaphragm 2 is resonated, and the large vibration is generated by that the weight 3 is rocked. On the other hand, when a sound of a high frequency is generated, since the weight 3 of the free end side of the piezoelectric diaphragm 2 hardly be vibrated, as it were the matter that both ends of the piezoelectric diaphragm 2 are supported occurs, and the piezoelectric diaphragm 2 is resonated. Thus, an excellent sound pressure level is obtained.
