AI Technical Summary
The motor in an electric toothbrush generates a lot of vibration and noise when it is working, which can cause the motor to collide with the casing and create noise problems.
Vibration damping components are used to filter the motor's vibrations, and flexible materials such as silicone or EVA cotton are connected to the housing structure to reduce vibration transmission.
It effectively reduces the vibration and noise of the motor during operation, improving the comfort and quietness of the electric toothbrush.
