Description

Technical Field

[0001] The utility model relates to the field of motors, and in particular to an anti-vibration motor with liquid silicone damping, a camera and an electronic device. Background Art

[0002] Taking photos has become an essential function for electronic products such as mobile phones and tablets, and motors are one of the important basic components for realizing this function. In the production process of the motor, after the semi-finished product is formed, it is usually necessary to apply damping glue between the reed and the carrier, and then use UV light to cure it so that the motor has a vibration reduction function. This method requires the application of damping glue, so there is a problem of poor leakage of damping glue. At the same time, after the damping glue is applied, UV light needs to be used for curing. Due to the attenuation of UV energy, there is also the problem of poor fixation of damping glue. At the same time, the damping itself is expensive, the storage conditions are harsh, and the shelf life is usually only 3 months, resulting in a high overall cost of use. Utility Model Content
