1. A piezoelectric power generator for feeding emergency power, comprising:
- a frame;
a fixing unit comprising a left fixing body coupled to a left part of the frame and a right fixing body coupled to a right part of the frame;
a first piezoelectric body attached to a right part of the left fixing body;
a second piezoelectric body attached to a left part of the right fixing body;
a vibration unit attached between the first piezoelectric body and the second piezoelectric body and configured to vibrate transversly to a direction extending between the right and left parts of the frame, wherein the vibration unit includes a Printed Circuit Board (PCB);
first and second masses respectively disposed inside an upper part and a lower part of the frame and configured to move vertically in the upper part and the lower part of the frame;
a first elastic unit connected between the first mass and a top end of the vibration unit; and
a second elastic unit connected between the second mass and a bottom end of the vibration unit.
