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
the present invention relates to the loud speaker field, particularly the magnetization method of the two major and minor magnetic of magnetic speaker of a kind of external magnetic type.
Background technology
magnetize and refer to the magnetized process of magnetic article, in the two magnetic speakers of external magnetic type are produced, need to use two blocks of magnetites of main magnetic and secondary magnetic, in existing technology, need two magnet chargers to magnetize to main magnetic and secondary magnetic respectively, again by the main magnetic after magnetizing, secondary magnetic is transported to together and is assembled, time and space have been wasted, simultaneously, different magnet chargers are when magnetizing, there are certain difference in the temperature of magnet charger board and voltage, make winner's magnetic, there is certain difference in the magnetic field of secondary magnetic, as shown in Figure 1-2, secondary magnetic 2 is put in respectively in two magnet charger boards 1 and magnetizes with the speaker frame 4 that main magnetic 3 is housed, main magnetic 3 has again magnetized, secondary magnetic 2 is transported to assembling together, easily cause main magnetic when assembling, secondary magnetic is relatively unstable, even produce the situation of repulsion or " secondary magnetic takeoffs ", bring inconvenience to production.
Summary of the invention
the magnetization method that the purpose of this invention is to provide the two major and minor magnetic of magnetic speaker of the stable external magnetic type of a kind of main magnetic, secondary magnetic.
for achieving the above object, the technical solution used in the present invention is: the magnetization method of the two major and minor magnetic of magnetic speaker of a kind of external magnetic type, at least one pair of main magnetic and secondary magnetosphere poststack are placed in magnet charger, magnetize after between described main magnetic and described secondary magnetic, being applied with the pressure that makes its contact-making surface close contact.
ordinal position when preferably, described main magnetic and described secondary magnetic are according to assembling is placed.
preferably, in magnet charger, described main magnetic and described secondary magnetic are placed with a pair of.
further preferably, described secondary magnetic is placed on the platform in described magnet charger, and described main magnetic is mounted in speaker frame, and described speaker frame is placed on the top of described secondary magnetic.
because technique scheme is used, the present invention compared with prior art has following advantages:
1, because the present invention is magnetized main magnetic and secondary magnetic simultaneously, only need a magnet charger just can complete the process of magnetizing, and after magnetizing without carrying after can carrying out the assembling of going, saved the time, manpower and the resources of production.
2, because the just main magnetic of the present invention and secondary magnetic magnetize simultaneously on a magnet charger, can guarantee that main magnetic and secondary magnetic energy enough have stable magnetic, when assembling, can avoid the situation of " secondary magnetic takeoffs " to occur.
The accompanying drawing explanation
accompanying drawing 1 is the schematic diagram that magnetizes of main magnetic in prior art;
accompanying drawing 2 is the schematic diagram that magnetizes of secondary magnetic in prior art;
the schematic diagram that accompanying drawing 3 is embodiment mono-;
the schematic diagram that accompanying drawing 4 is embodiment bis-.
in above accompanying drawing: 1, magnet charger board; 2, secondary magnetic; 3, main magnetic; 4, speaker frame; 5, Antimagnetic hood.
Embodiment
below in conjunction with embodiment shown in the drawings, the invention will be further described:
embodiment mono-: shown in accompanying drawing 3, secondary magnetic 2 is placed on magnet charger board 1, the speaker frame 4 that main magnetic 3 will be installed again is placed on secondary magnetic 2, apply certain downward pressure on speaker frame 4, guarantee the position relationship of main magnetic 3 and secondary magnetic 2 in the process of magnetizing, open the magnet charger switch and magnetized.
main magnetic 3 after magnetizing is relative with the magnetic pole of secondary magnetic 2, can weaken the magnetic field intensity of loud speaker, in the time of assembling, secondary magnetic 2 reversing assemblings is got final product.
embodiment bis-: shown in accompanying drawing 4, secondary magnetic 2 is arranged in Antimagnetic hood 5, Antimagnetic hood 5 is upside down on magnet charger board 1, the speaker frame 4 that main magnetic 3 will be installed again is placed on secondary magnetic 2 tops, apply certain downward pressure on speaker frame 4, guarantee the position relationship of main magnetic 3 and secondary magnetic 2 in the process of magnetizing, open the magnet charger switch and magnetized.
after magnetizing, Antimagnetic hood 5 upsets and speaker frame 4 assemblings are got final product.
above-described embodiment magnetizes main magnetic 3 and secondary magnetic 2 simultaneously, only need a magnet charger just can complete the process of magnetizing, and the assembling of going after can carrying out without carrying after magnetizing, saved the time, manpower and the resources of production, simultaneously, can guarantee that main magnetic 3 and secondary magnetic 2 can have stable magnetic, when assembling, can avoid the situation of " secondary magnetic takeoffs " to occur.
above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
