1. What function do you want to achieve?
2. Does the program have congenital defects?
3. How to overcome the defect and achieve the desired function?
1. Choose products that are triggered by the South Pole magnetic field, by the the North Pole magnetic field, or by the North and South magnetic fields?
2. What type of package is suitable for the sensor at the location?
1. Is the magnetic circuit structure design reasonable?
2. Does the magnetic field strength meet the sensor requirements? Does the magnetic field of the left and right earphones interfere with each other? Does the adsorption magnet affect the sensor work?
1. Analyze the problem of defective magnetic circuit products, whether it is the magnet work difference or the assembly work difference, and guide the direction of rectification.
