The piezo buzzer is when debugs the measuring appliance eliminates the hysteretic damping one kind of equipment, uses many in astronautics aviation industry debugging measuring appliance. The cicada calls the vibration magnitude size to debug measuring appliance's precision influence to be very big, but for many years home was not unified to buzzer's vibration technology standard. Elaborated each kind of cicada calls the basic principle, the test result which vibrated according to the domestic and foreign airplanes proposed one kind of vibration technology standard, passed through the test effect to be good.
