Abstract
Disclosed are an auxiliary magnetic structure of a loudspeaker and an assembling method of the auxiliary magnetic structure. The structure comprises a hollow frame, a lower piece, a primary magnet, an auxiliary magnet, a primary magnet pole piece and an auxiliary magnet piece, wherein the lower piece is arranged at the bottom of the frame, the primary magnet and the auxiliary magnet are arranged on the lower piece, the primary magnetic pole piece is arranged on the primary magnet and an auxiliary magnetic pole piece arranged on the auxiliary magnet. The auxiliary magnetic structure and the assembling method of the auxiliary magnetic structure are applicable to the light and thin loudspeaker and the primary magnet and the auxiliary magnet are convenient to install.
Description
Technical field
the present invention relates to the loud speaker field, relate in particular to a kind of secondary magnetic structure and assemble method thereof of loud speaker.
Background technology
In
prior art, the secondary magnetic structure of loud speaker is by two kinds of conventional design.A kind of conventional design a as shown in Figure 1 causes the thickness of loud speaker bigger because secondary magnetic 2 is combined with main pole sheet 6 bondings, and this type of design is not suitable for the light and thin type loud speaker.
a kind of conventional design b and for example shown in Figure 2; Secondary magnetic magnetic pole 2, main magnetic 5 are assembled with following sheet 4 respectively, and the integral body after will assembling is again packed in the framework 1, have influenced the installation of main magnetic 5, secondary magnetic 2 because of the interaction between main magnetic 5 and the secondary magnetic 2; When assembling, exist secondary magnetic 2 to be inhaled the situation of falling by main magnetic 5; Though can satisfy the loud speaker of light and thin type, installation difficulty is bigger, be inconvenient to produce.
These all are the locate mode of general secondary magnetic for
, and these two kinds of existing conventional designs are all not exclusively suitable for the loud speaker of light and thin type, therefore, need a kind of new secondary magnetic structure and assemble method thereof.
Summary of the invention
It is little that
the purpose of this invention is to provide a kind of overall volume, secondary magnetic structure of the loud speaker of stable performance and assemble method thereof.
are for achieving the above object; The technical scheme that the present invention adopts is: a kind of secondary magnetic structure of loud speaker; It comprises hollow framework, be arranged on following of said base of frame, be arranged on main magnetic and secondary magnetic on the said sheet down, be arranged on main pole sheet on the said main magnetic, be arranged on the secondary magnetic pole sheet on the described secondary magnetic, be provided with the fixed card slot that matches with said secondary magnetic pole sheet in the said framework.
The secondary magnetic structure assemble method of above-mentioned loud speaker may further comprise the steps successively into:
With said secondary magnetic and the fixing assembling of said secondary magnetic pole sheet; With said main magnetic and the fixing assembling of said main pole sheet;
With described secondary magnetic pole sheet and said fixed card slot contraposition assembling and fixing;
Said main magnetic fixation group is contained on the said sheet down;
are with described sheet down and said framework aggregate erection and fixing.
preferably, said secondary magnetic pole sheet and said draw-in groove adopt some glue to fix.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, because the present invention is fixedly mounted on secondary magnetic and secondary magnetic pole sheet in the framework draw-in groove earlier, and main magnetic and following sheet are installed in the back, prevents to have influenced the installation of main magnetic, secondary magnetic because of the interaction between main magnetic and the secondary magnetic; When main magnetic, negative magnetic interaction, secondary magnetic and secondary magnetic pole sheet firmly are fixed in the framework, can not influence the installation of main magnetic, the difficulty when having reduced main magnetic, secondary abampere dress;
2, because master's magnetic of the present invention, secondary magnetic potential in same horizontal plane, have effectively reduced whole height, be applicable to the light and thin type loud speaker more.
Description of drawings
Accompanying drawing 1 is conventional design a;
Accompanying drawing 2 is conventional design b;
Accompanying drawing 3 is looked cutaway view for master of the present invention;
Accompanying drawing 4 is framework of the present invention and secondary magnetic structure vertical view;
accompanying drawing 5 is the partial enlarged drawing of accompanying drawing 4.
In
above accompanying drawing: 1, framework; 2, secondary magnetic; 3, secondary magnetic pole sheet; 4, following sheet; 5, main magnetic; 6, main pole sheet; 7, fixed card slot; 8, place, location.
Embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described:
embodiment one: shown in accompanying drawing 3; A kind of secondary magnetic structure of loud speaker; It comprises hollow framework 1, be arranged on following 4 of said framework 1 bottom, be arranged on main magnetic 5 and secondary magnetic 2 on the said sheet 4 down, be arranged on main pole sheet 6 on the said main magnetic 5, be arranged on the secondary magnetic pole sheet 3 on the described secondary magnetic 2, be provided with the fixed card slot 7 that matches with said secondary magnetic pole sheet 3 in the said framework 1.
When install
, earlier with 3 fixing assemblings of affiliated secondary magnetic 2 and said secondary magnetic pole; With said main magnetic 5 and said main pole sheet 6 fixing assemblings; Again described secondary magnetic pole sheet 3 and said fixed card slot 7 are located 8 contrapositions assembling according to the location and fix with putting glue; Again said main magnetic 3 fixation group are contained on the said sheet 4 down; At last with described sheet 4 down and said framework 1 aggregate erection and fixing.
because present embodiment is fixedly mounted on secondary magnetic 2 in the framework draw-in groove 7 with secondary magnetic pole sheet 3 earlier, and main magnetic 5 and following sheet 4 are installed in the back, prevents to have influenced because of the interaction between main magnetic 5 and the secondary magnetic 2 installation of main magnetic 5, secondary magnetic 2; At main magnetic 5, when negative magnetic 2 interacts, secondary magnetic 2 firmly is fixed in the framework 1 with secondary magnetic pole sheet 3, can not influence the installation of main magnetic 5, has reduced main magnetic 5, the difficulty when secondary magnetic 2 is installed.
the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
