Abstract :
Bimorph based double amplifier actuator is a new type of piezoelectric actuation structure which combines both bending and flextensional amplification concepts. As a result the displacement of the actuator can be more than ten times larger than the tip displacement and can be used in air acoustic transducers as an actuation element. This paper studied the dependence of displacement on actuator parameters and optimum design issues for the cover plate (the flextensional part of the actuator) theoretically and experimentally
