The Technical Principle of Ultrasonic Directional Sound Transmission
High-directivity audible sound is generated by the nonlinear interaction of ultrasonic waves in the air, that is, the sound signal is controlled to propagate in a high-direction manner within a specified range & angle.
For sound waves to have directivity, the conditions need to be met: the wavelength of the sound waves is close to or even much smaller than the size of the sound source. Therefore, the sound waves emitted by the ultrasonic transducer have directivity.
We can offer kinds of parametric speaker for sale, if you have needs to buy a parametric speaker, please leave us a message.
