AI Technical Summary

Technical Problem

The thickness of the coil in existing vibration motors compresses the volume of the oscillator, making it difficult to improve the vibration effect. At the same time, it is impossible to observe the internal situation after assembly.

Method used

A through hole is made inside the housing of the vibration motor, and the coil is sunk into the through hole and fixed with glue. This frees up height space to increase the mass of the oscillator, and the internal situation can be observed through the coil through hole. PET film is used for waterproofing and dustproofing, and laser welding is used to enhance the reliability of the connection.

Benefits of technology

The improved quality of the oscillator enhances the vibration effect and allows for observation of the internal structure, ensuring the motor's sealing and reliability.
