Patent ID: 7291828

Claim:
A measuring system for determining electromechanical coupling characteristics of a PZT vibrator which comprises: an elastic-bouncing tester, which can load an object and confine bouncing motion of the object in the elastic-bouncing tester, said elastic-bouncing tester including a PZT vibrator; a driving circuit, which is powered to activate the bouncing motion of the object in the elastic-bouncing tester; a height measuring circuit, which can measure the bouncing position of the object in the elastic-bouncing tester; an instantaneous height indicator, which instantaneously shows the bouncing height of the object in the elastic-bouncing tester in bouncing motion; a microprocessor, which processes, stores, and presents bouncing motion signal of the object in the elastic-bouncing tester; and a monitor, which shows the measured bouncing motion signal of the object; and a push-button switch circuit, which provides functions in response to kinds of operation modes.
