Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- magnetic poles axle center, 2- voice coil loudspeaker voice coils, 3- magnetic gaps, the upper magnetic conductive splints of 4-, 5- magnets, magnetic conductive splint under 6-.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, it is a kind of reduce magnet temperature rise dynamic loudspeaker magnetic structure, including magnetic pole axle center 1, voice coil loudspeaker voice coil 2, on
Magnetic conductive splint 4, magnet 5 and lower magnetic conductive splint 6, the magnetic pole axle center 1 is directly over lower magnetic conductive splint 6, and magnetic pole axle center 1 is with
The riveted of magnetic conductive splint 6；Magnet 5 is bonded on lower magnetic conductive splint 6 by jig and glue, and upper magnetic conductive splint 5 passes through positioning
Mould and glue are bonded in the top of magnet 5；Upper magnetic conductive splint 4 is located at the outside of magnetic pole axle center 1, magnetic pole axle center 1 and upper magnetic conductive splint 4
Between be provided with magnetic gap 3, voice coil loudspeaker voice coil 2 is located in magnetic gap 3.
Further, the height and the height phase at the top of magnetic pole axle center 1 at the top of upper magnetic conductive splint 4 described in the utility model
Together.
Further, the left and right sides at the left and right sides edge of upper magnetic conductive splint 4 described in the utility model and lower magnetic conductive splint 6
Edge is concordant.
Further, the height of upper magnetic conductive splint 4 described in the utility model for the height of magnetic pole axle center 1 more than 4/5 and it is small
Height in magnetic pole axle center 1.
Operation principle of the present utility model is：
First by magnetic pole shaft core 1 and the lower riveted of magnetic conductive splint 6, then magnet 5 is bonded in by jig and glue
On lower magnetic conductive splint 6, after waiting magnet 5 and the lower glue curing of magnetic conductive splint 6, then upper magnetic conductive splint 4 passed through into jig and glue
Water is bonded together with magnet 5.After whole magnetic circuit system is fully cured, magnetized by outside magnet charger, form a complete magnetic
Circuit system.
After the volume of upper magnetic conductive splint 4 increases, area of dissipation lifting is obvious, and the distance ratio tradition of magnet 5 and magnetic gap 3
