Problems solved by technology

[0002]Magnetization refers to the process of magnetizing magnetic items. In the production of external magnetic double magnetic speakers, two magnets, the main magnet and the auxiliary magnet, are needed. The existing In the technology, two magnetizers are required to magnetize the main magnet and the auxiliary magnet respectively, and then the magnetized main magnet and auxiliary magnet are transported together for assembly, which wastes time and space. At the same time, different magnetizers are During magnetization, there are certain differences in the temperature and voltage of the magnetizing machine, which makes the magnetic fields of the main magnet and the auxiliary magnet have certain differences, such as As shown in Figure 1-2, the auxiliary magnet 2 and the speaker frame 4 with the main magnet 3 are respectively placed in two chargers Magnetize in the magnet machine machine 1, and then carry the main magnet 3 and auxiliary magnet 2 together for assembly. During assembly, it is easy to cause the main magnet and auxiliary magnet to be relatively unstable, and even repulsion or "auxiliary magnet jumping" will occur. The situation has brought inconvenience to the production

Embodiment 1

[0017] Embodiment one: see attached image 3 As shown, place the auxiliary magnet 2 on the magnetizer machine 1, then place the speaker frame 4 with the main magnet 3 on the auxiliary magnet 2, and apply a certain downward pressure on the speaker frame 4 to ensure that the During the magnetization process, the positional relationship between the main magnet 3 and the auxiliary magnet 2 remains unchanged, and the magnetizer switch is turned on for magnetization.

[0018] After magnetization, the magnetic poles of the main magnet 3 and the auxiliary magnet 2 are opposite to each other, which will weaken the magnetic field strength of the speaker, and the auxiliary magnet 2 can be assembled upside down during assembly.

Embodiment 2

[0019] Embodiment two: see attached Figure 4 As shown, the auxiliary magnet 2 is set in the magnetic shield 5, the magnetic shield 5 is turned upside down on the magnetizer machine 1, and the speaker frame 4 with the main magnet 3 installed is placed above the auxiliary magnet 2, and the speaker frame 4 Apply a certain downward pressure on the top to ensure that the positional relationship between the main magnet 3 and the auxiliary magnet 2 remains unchanged during the magnetization process, and turn on the switch of the magnetizer for magnetization.

[0020] After magnetization, turn over the magnetic shield 5 and assemble it with the speaker frame 4 .

[0021] In the above embodiment, the main magnet 3 and the auxiliary magnet 2 are magnetized at the same time, only one magnetizer is needed to complete the magnetization process, and after magnetization, the subsequent assembly can be carried out without transportation, which saves time, manpower and production Resou...

Abstract

The invention discloses a method for magnetizing main and subsidiary magnets of external-magnetic dual-magnet loudspeaker. The method comprises the steps of laminating at least one pair of main and subsidiary magnets and then magnetizing. According to the method, the main and subsidiary magnets are magnetized simultaneously, so that a magnetizing process can be completed by only one magnetizer; subsequent assembly can be carried out without transporting after magnetizing, so that time, labor and production resources are saved; the main and subsidiary magnets are magnetized simultaneously on the same magnetizer, so that the main and subsidiary magnets can have stable magnetism, and the occurrence of subsidiary magnet jumping can be avoided during assembly.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a method for magnetizing the main and auxiliary magnets of an external magnetic dual-magnet loudspeaker. Background technique [0002] Magnetization refers to the process of magnetizing magnetic items. In the production of external magnetic dual-magnet speakers, two magnets, the main magnet and the auxiliary magnet, are needed. In the existing technology, two magnetizers are required for the main magnet and the auxiliary magnet respectively. Magnetizing, and then transporting the magnetized main magnet and auxiliary magnet together for assembly, wastes time and space. At the same time, when different magnetizing machines are magnetizing, the temperature and voltage of the magnetizing machine have certain differences. The difference makes the magnetic fields of the main magnet and the auxiliary magnet have certain differences, such as Figure 1-2 As shown, the auxiliary magnet 2 and th...
