ABSTRACT

Directional propagation of acoustic waves based on ultrasonic modulation is a hot research topic in recent years. Through the study of the principle of acoustic directional emission, a complete set of acoustic directional transmitters was constructed using specific circuits and devices. After testing, a clear sound orientation effect was obtained. Therefore, designing and researching high-intensity, high-stability acoustic directional emitters is the key to this paper.
