A Virtual Instruments based system for underwater electroacoustic transducer calibration was developed to automatize underwater acoustic measurements.

With the rapid development of underwater acoustic signal processing technique,more and more information needs to be obtained from transducers,and the working frequency band of underwater acoustic transducers ought to be broader.

It is suit for the production of the underwater acoustic transducer and ultrasound transducer.

The mathematics model of this piezocomposite underwater acoustic transducer array is established.

Pointing to the existing problem in the traditional underwater transducer test, an auto-measuring underwater transducer with virtul instument and through computer control plan is proposed.

The research of underwater transducer and transducer array is playing a decisive role in the development of modern marine military equipment.

Acoustic Transducer and Its Research & Development;

A survey of important role and main characters of acoustic transducer is introduced at first.

Sound etalon is an acoustic measurement equipment of great significance according to the National Measurement Calibration Standards——JJG176-95, a sound etalon is required to conduct calibration in three indexes, i.
