This is the first time I have heard of this product, but I understand it literally. It is an instrument that uses infrasound waves (low-frequency sound waves) to penetrate human tissues and induce them to vibrate slightly, so as to dredge meridians. This requires high precision of the instrument. Physiologically, the vibration frequency of different tissues in human body is different, which will cause injury. Moreover, the appearance of this product means that it must go through long-term clinical trials to prove that the product design has no side effects before it can be put into use.
It should also be noted that during my postgraduate study abroad, there were departmental seminars every week, all of which were sent by enterprises. Therefore, this principle has hardly been used in the acoustic instruments I have contacted. I have only seen a device that uses this principle to kill pests. Personally, I suggest you think twice before you act. If this is a domestic product, I suggest not to use it, not because you look down on domestic products, but because the supervision in China is not very strict, and the safety of immature products is not flattering.
