Background technique

In recent years, with the rapid development of the economy and the rapid improvement of people's living standards, people are enjoying the fruits of modern civilization. At the same time, civilized diseases, that is, lifestyle diseases are becoming increasingly popular, and more and more people are in a sub-health state. Some people, especially children and the elderly, are obese due to excessive intake of high-calorie foods and lack of exercise. For these people, weight loss through exercise may induce other effects. For people who drive for a long time, work in front of a computer for a long time, and play games, it is most prone to fatigue damage of the shoulders, arms, and lumbar vertebrae. Therefore, there is an urgent need for a device that can effectively alleviate physical fatigue.

The theory of sound wave vibration system comes from sound wave medicine. It is a kind of edge medicine that integrates the knowledge collection of many subjects such as traditional Chinese medicine, modern medicine, modern acoustic physics, information science and computer technology. It believes that the human body itself is a vibration source, and human cells and organs also produce sounds that make up the body's own special sound. In fact, every organ, bone, tissue and various physiological systems of the human body have its own vibration frequency, and these frequencies add up to constitute the vibration frequency of the human. The medical principle of the sonic vibration system is that after the sound vibrates into the human body, it can change the vibration frequency of the human body, make the body resonate with it, change the vibration frequency of the unbalanced part, and return the body to the equilibrium state.

Such vibrators are difficult to achieve precise control of vibration frequency and vibration amplitude. When the set vibration frequency is lower than 20 Hz, it is difficult to achieve the expected. Vibration effect.

A failure was detected and the user was alerted.
