Ultrasound is very useful and is used in all walks of life, such as medical, household, and industrial, which is indispensable.

1. Ultrasonic humidifier: ultrasonic waves pass into the water tank, and the violent vibration will break the water in the tank into many small droplets, and then use a small fan to blow the droplets into the room, which can increase the indoor air humidity.

2. Ultrasonic ranging: ultrasonic waves have strong directionality and are easy to reflect when encountering obstacles, so the ultrasonic locator can detect the position of submarines, fish schools and the depth of the ocean.

3. Ultrasonic scaling: The high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation through the transducer, and then propagated to the medium, destroying the insoluble dirt and dispersing it in the cleaning solution.

Extended Information: Ultrasound waves travel much more energy than audible sound. Because when the sound wave reaches a substance, the molecules in the substance also vibrate due to the action of the sound wave, and the frequency of the vibration is the same as the frequency of the sound wave, so the molecular vibration frequency determines the speed of the molecular vibration, and the higher the frequency, the greater the speed.

In addition to the mass of the molecule, the energy is also proportional to the square of the vibration speed of the molecule, and the vibration speed is related to the frequency of the molecule's vibration, so the higher the frequency of the sound wave, that is, the higher the energy obtained by the substance molecule. The frequency of ultrasound waves can be much higher than that of sound waves, so ultrasound can cause more energy to be obtained by the molecules of matter. This shows that the ultrasound itself can supply a large enough amount of energy to the substance.

Ultrasound has a variety of uses.

Ultrasound can be used for cleaning, eyeglasses, teeth cleaning, etc. In industrial production, it can be used to clean a variety of workpieces.

Ultrasonic waves can be used for welding.

Ultrasound can be used in medicine**.

Ultrasound can be used for cutting.

Ultrasound can be used for speed measurement.

Ultrasonic waves are used for many purposes, and the general direction can be divided into power ultrasound and detection ultrasound. Power ultrasonic includes: ultrasonic cleaning, ultrasonic welding, ultrasonic atomization, phacoemulsification, ultrasonic separation, ultrasonic processing, ultrasonic extraction, etc.

Ultrasonic detection includes: ultrasonic ranging, ultrasonic current measurement, ultrasonic wind measurement, ultrasonic positioning, ultrasonic communication, ultrasonic obstacle avoidance, ultrasonic imaging, ultrasonic temperature measurement, etc.
