1 , Neodymium Ring Magnets Application :
|
Acoustic field |
the speaker, receiver, microphone, alarm, stage audio, car audio. |
2 , Higher Grade , Stronger Power
The Grade / Model for the Neodymium Ring Magnets is higher , the power is stronger .
Like N35 less than N38 N38 less than N40 etc.
3 . Other Size We Can Work :
Block: Length x Width x Thickness
Disc / Cylinder: Diamter x Thickness
Ring: External Diamter x Internal Diameter x Thickness
Segment: According to the drawing
Irregular: According to the drawing
