Acoustic waves are the form of propagation of the mechanical vibration state (or energy) of an object. Ultrasound refers to the vibration frequency is greater than 20000Hz above, its frequency of vibration per second (frequency) is very high, beyond the general limit of human hearing (20000Hz), people will call this inaudible sound waves called ultrasound. Because of its high frequency, it has many characteristics: First, it has a large power, and its energy is much larger than the general sound wave, so it can be used for cutting, welding, drilling and so on. Furthermore, because of its high frequency, short wavelength, and poor diffraction, it has good directionality, and ultrasound is commonly used in industrial and medical applications for ultrasonic detection. [1] Ultrasound and audible sound are essentially the same. Their common point is a kind of mechanical vibration mode. It usually propagates in the elastic medium in the form of longitudinal waves. It is a form of energy transmission. Its difference is Ultrasonic frequency is high, the wavelength is short, and it has good beam directionality and directivity in a straight line within a certain distance, 1 megahertz=10^6Hz, ie each

The second vibration is 1 million times, and the frequency of the audible wave is between 16-20000HZ).

Company introduction:
Established in 1999, Beijing Cheng-cheng Weiye Science and Technology Co., Ltd is a professional manufacturer in ultrasonic transducers, ultrasonic equipment and piezoelectric ceramics.
Notably in 2004, we researched and developed our ultrasonic tubular transducer equipment into a new product that turns the extreme inconvenience brought about by pipeline and vacuum cleaning into an easy task. This product has been widely used in distillation, mix and mill for various chemical procedures and has received much praise from our customers.
