Assembling method of magnetic circuit system and magnetizing system

Abstract

The present invention discloses an assembling method of a magnetic circuit system and a magnetizing system. The method comprises the steps of: fixing a centring magnet without magnetizing and a side magnet without magnetizing on a magnetic conductive yoke, wherein the side magnet is arranged at the outer periphery of the centring magnet, and a gap between the centring magnet and the side magnet; performing magnetizing for any one of the side magnet and the centring magnet; applying the magnetic field with polarity opposite to a corresponding magnetic pole to the magnetizing one of the side magnet and the centring magnet to perform magnetic protection; and performing magnetizing for the magnetizing one of the side magnet and the centring magnet to form a magnetic field in the gap.

Description

technical field

[0001] The present invention relates to the technical field of magnetization, and more specifically, to a method for assembling a magnetic circuit system and a magnetization system. Background technique

[0002] In a multi-magnetic circuit acoustic module, it is usually necessary to magnetize the side magnets and the center magnets separately first; then assemble the center magnets and side magnets on the magnetic yoke. However, both the center magnet and the side magnets are magnetic. During assembly, the two magnets are usually fixed to the magnetic yoke by bonding. Due to the attractive force or repulsive force generated between the central magnet and the side magnets and between multiple side magnets, the relative positions of the central magnet and the side magnets will be shifted. Therefore, when assembling, only low-temperature glue with a small bonding force can be used for bonding, so that the relative positions of the center magnet and the side ma...
