In the wave of rapid development of science and technology ,sound positioning plays an increasing! important role in our daily life. Traditional sound localization technology is often limited by complex sign a analysis and high dependence on professionals, while the emerging optical assisted sound localization technology shows unprecedented potential. This study is devoted to the study of an innovative sound position in device based on Lissajous graphics prineiple, aiming to realize the innovative positioning method of sound source through optical visualization technology, The design of the device fully considers the practicability versatility and operability, It adopts a simple structure and combines the principles of optics , acoustics and vibration to realize the visual presentation of sound signals, thus significantly improving the accuracy and efficiency of positioning.
