This appearance is very regular, and it is easy to arrange the ultrasonic motor and the vibration-penetrating mechanism. For structural engineers, the problem is not big. This should be the designer's early concept map, and the structure has not been made yet.

By the way

It is an ultrasonic motor, such as an electric toothbrush. The principle of the ultrasonic motor is the piezoelectric effect of piezoelectric ceramics. The driving signal is a 13KHz ~ 23KHz high-frequency square wave, which can disperse dirt and water is easier to wash away dirt. This is the basic principle process of the product.

That's what I said... but I don't think there is any use for electric toothbrush hair... I bought one earlier and threw it away once · ·

I'm talking about human words what you said is to fool the old people

Ignorance ≠ human words

I really haven't made this kind of product. What I want to express is that people pay more attention to the design itself, rather than a gimmick that has nothing to do with the design. For example, the super-Shenbo face-washing massager, which just came out and sold for thousands of yuan. In fact, it is a motor when bought and disassembled. In fact, it is also a built-in motor. In fact, it is also a 10, the essence is also several motors with different frequencies. I have come into contact with these projects, so I just want to say what I know. You don't need to target the word ultrasound, which is not friendly to people, and the author is not studying ultrasound · ·

You may object, but I reserve my opinion of you.
