The height reduction of sound device, it is cost-effective.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：
Fixing hole is provided with the middle part of inside and outside double folding ring loudspeaker, including outer framework, outer framework and U-shaped magnetic conductor, U-shaped is connected with
The bottom surface of magnetic conductor is bonded with main permanent magnet, upper magnetic conductor and secondary permanent magnet successively from bottom to up；The upper end of outer framework is bonded
Have and vibrating basin is connected with the inside of outer ring, outer ring, the medial extremity of interior ring is adhered to secondary permanent magnet；Also include voice coil loudspeaker voice coil, sound
The upper end of circle is connected with vibrating basin and interior ring outer radius respectively, between the lower end insertion U-shaped magnetic conductor of voice coil loudspeaker voice coil and upper magnetic conductor
Gap.
Further, interior ring includes the interior adhesive portion positioned at inner side, the elastic portion positioned at middle part and positioned at the outer of outside
Adhesive portion, wherein interior adhesive portion is adhered to secondary permanent magnet, outer adhesive portion is adhered to the medial extremity of vibrating disk.Preferably, elastic portion
Shape can select the shape of the conventional ring of in the market.Elastic portion semicircular in shape, serpentine or " M " shape.
Further, the upward magnetic conductor direction bending of the medial extremity of vibrating disk, forms between medial extremity and outer adhesive portion and holds
Between being empty, accommodation space is provided with adhesive linkage, and the upper end of voice coil loudspeaker voice coil is Nian Jie with adhesive linkage through the mesopore of vibrating basin.The inner side of vibrating disk
End is adhesively fixed on voice coil loudspeaker voice coil by adhesive linkage.
Further, in addition to terminal plate, terminal plate is fixed on the outside of outer framework, and terminal plate is stretched into one end of connecting line
Coupled in hole by scolding tin, the other end of connecting line and the lead-out wire of voice coil loudspeaker voice coil are connected.
The beneficial effects of the utility model are：The utility model can both be ensured by the cooperation of interior ring and vibrating disk
The axial movement of voice coil loudspeaker voice coil is smooth, it is ensured that tonequality；The height of loudspeaker can be reduced again simultaneously.
Brief description of the drawings
Fig. 1 is the schematic diagram of prior art.
