This section provides an overview for ultrasonic generator as well as their applications and principles. Also, please take a look at the list of 10 ultrasonic generators manufacturers and their company rankings.
Ultrasonic waves are air vibrations with a frequency of 20 kilohertz or higher, and are sounds that cannot be felt by humans.
To produce such ultrasonic waves, it is necessary to vibrate an object at a high frequency and to vibrate the air around the object. Commonly used are what are called piezoelectric elements.
This is based on the property (piezoelectric effect) of a piezoelectric element to stretch or shrink when a voltage is applied to it, depending on the polarity of the voltage.
When an AC voltage is applied from an electrode connected to the piezoelectric element, the element vibrates at high speed due to the piezoelectric effect and generates ultrasonic waves.
Ultrasonic generators are used in a wide range of applications, from everyday situations to industrial fields.
For example, they can be used for liquids containing liquid or solid particles to produce emulsions or to prepare samples or pigments.
Often used in academic and industrial fields, ultrasonic waves are used to clean mechanical and electronic parts.
In the humidifier, ultrasonic generators are used to atomize the liquid to produce a mist.
The piezoelectric element used in ultrasonic generators are a type of ceramic made of titanium oxide, barium oxide, or other materials baked and hardened at high temperatures.
One of the characteristics of this element is that when pressure is applied externally, a voltage is generated in the element.
The reason why voltage is generated when pressure is applied to a solid is due to the distortion of the crystal structure in the solid by the application of pressure.
Positive and negative ions are arranged in the solid, and external forces distort the positions of these ions, causing charge bias in the solid.
As a result, electrical polarization occurs and voltage is generated within the solid.
Conversely, it can be understood that the crystal structure is changed by the application of voltage and the position of the ions is moved by the electric field, resulting in a change in the thickness of the solid.
When a high-frequency AC voltage is applied to this piezoelectric element, the element expands and contracts at high speed, rapidly generating longitudinal waves (sound), which are emitted as ultrasonic waves.
