During the driving process of the car, in addition to the vibration source of the car itself (such as the engine, etc.), there are also irregular forced vibrations caused by uneven road surfaces. These vibrations have a great impact on the normal operation of on-board electronic equipment. When automobile manufacturers solve this kind of vibration isolation problem, they usually adopt the method of adding anti-vibration gaskets to on-board electronic equipment or relying on supporting manufacturers to provide products with certain vibration damping devices. However, the vibration of the automobile during driving is complex (both high frequency and low frequency), so the effect of adopting the above method is very limited, and the purpose of solving vibration isolation cannot be well achieved.
