Abstract
This paper deals with the vibration and acoustic characteristics of ultrasonic sensors for distance measurement according to the housing structure. To magnify the distance range, it is necessary to increase the vibration magnitude of the vibrating plate of the ultrasonic sensor. We consider the modifications of axisymmetric housing, its thickness, and boundary of the plate and cylinder wall. We compare the characteristics of the modified housing structures by the finite elements analyses of vibration and acoustics. The flexibly-modified boundary of the vibrating plate allows a larger vibration and sound pressure along the distance. We identified the sensor structure of the larger ultrasound power for the given input signal.
