Abstract

According to the research of acoustic directivity by using MATLAB software, selection of a relatively larger surface of the transducer and a relatively closer transducer interval will be more preferable for directivity. On the other hand, when the structure of the sound radiating surface of the transducer or array layout is symmetrical, the corresponding directivity pattern will be symmetrical. The two resonance frequencies of a single transducer and a transducer array are measured by an impedance analyzer. And according to the resonant frequency 23kHz, high-power directivity acoustic transducer hardware experiment platform is designed. And this design, which can successfully drive sound transducer array and the drive power is about 10w, can ensure that the ultrasonic signal’s amplification will be performed without distortion, while the magnification can reach to 20 times. In order to test transducer’ directivity, two methods are designed.
