An ultrasonic cannon, also known as an ultrasonic horn, is a device that utilizes high frequency sound waves to produce ultrasonic waves. Ultrasonic cannons can generate extremely strong sound pressure at a specific frequency, which produces high-frequency sound waves. This sound wave is extremely penetrating and can penetrate some solid materials. At present, the ultrasonic gun is mainly used in many fields such as sonar, pressure detection, cleaning and so on.
The ultrasonic gun mainly utilizes the piezoelectric effect to generate ultrasonic waves. By applying an electric field, a quartz crystal can be compressed or elongated to generate sound waves. This method is often referred to as the long wave drive mode. Ultrasonic guns can emit millions of cycles of high-frequency sound waves in a very short period of time, with frequencies typically ranging from a few kilohertz to several million hertz. Utilizing the penetrating power of ultrasound, it is capable of emitting extremely strong sound pressure.
Ultrasonic cannons can be used in a number of applications, such as sonar detection, pressure detection, inspection and cleaning. In sonar detection, ultrasound can penetrate deep ocean water and detect the location of the sound source. In pressure detection, ultrasound can be applied to detect the pressure and flow rate of gases and liquids. In manufacturing, ultrasonic guns are often used to detect defects in materials or products, such as cracks and foreign objects. In the field of cleaning, ultrasound can also be used for controlled cleaning and removal of dirt from the surface of materials.
