Description
Technical field
The utility model relates to a kind of loud speaker, relates in particular to a kind of magnetic circuit structure for loudspeaker.
Background technology
in recent years, development along with electronics technology industry and material science, electronic product miscellaneous gets frivolous little future development in the past, but be applied in the loud speaker on electronic products such as television set, automobile audio, owing to the magnetic circuit assembly being placed in the outside of jolting plate, cause that its volume is large, thickness is thicker, thereby affect electronic product to frivolous little future development, in addition, because the price of iron in recent years is constantly soaring, and the magnet steel in the magnetic structure of prior art mostly adopts iron core, has therefore caused the raising of manufacturing cost, the existing LCD that is applied to, the loud speaker of the plate video equipment such as PDP, the general airtight basin frame in bottom that adopts, dispensed U-shaped conductive magnetic yoke structure, make loud speaker thickness further be optimized, further use again an auxiliary magnet, improve the magnetic flux density that reduces because saving U-shaped conductive magnetic yoke, the acoustic performance of loud speaker is improved, to be applicable to the novel flat-plate video equipment, but, the loud speaker of this kind structure is plane due to basin frame airtight bottom, magnetic circuit system is arranged on this plane basin frame bottom and is not easy the location, can cause magnetic circuit installation site skew, cacophonia when easily causing speaker operation, and be unfavorable for the magnetic circuit of loudspeaker assembling, requiring main magnet in the loud speaker inner magnetic structure is opposite with secondary magnet polarity, if but our naked eyes that in process of production main magnet and secondary magnet same polarity bonded together are in the situation that not do sign be to feel can not check, if will increase operation but do sign, but the product that has the same polarity poor attachment produces, therefore, there is defective in prior art, need to improve.
The utility model content
Main purpose of the present utility model is to overcome the deficiencies in the prior art, and a kind of designs simplification is provided, and volume is little, accurate positioning, and assembling is simple, improves the magnetic circuit structure for loudspeaker of product yield.
for achieving the above object, the utility model rice used following technical scheme: a kind of magnetic circuit structure for loudspeaker, comprise the basin frame, set gauge, magnetic sheet, main magnet, secondary magnet, described set gauge middle part arranges the magnetic sheet bayonet socket, described magnetic sheet is arranged on magnetic sheet bayonet socket place, described magnetic sheet bayonet socket downside arranges secondary magnet bayonet socket, described secondary magnet is fixed on secondary magnet bayonet socket, described secondary magnet bayonet socket downside arranges main magnet bayonet socket, described set gauge extends the magnet faceplate along main magnet bayonet socket sidewall, described main magnet is fixed on bottom the basin frame, bottom described main magnet and basin frame, sidewall has the space that adapts with magnet faceplate thickness, described set gauge is by magnet faceplate clamping basin frame,
Described set gauge adopts plastic-steel material to make;
Described main magnet upper end is provided with magnetic pole core;
Described main magnet is opposite with two magnetic pole installation directions of secondary magnet, and described secondary magnet is consistent with two magnetic pole installation directions of magnetic sheet.
beneficial effect with respect to prior art is, main magnet is fixed on bottom the basin frame, bottom main magnet and basin frame, sidewall has the space that adapts with magnet faceplate thickness, set gauge can pass through magnet faceplate clamping basin frame, assemble simpler, the magnetic sheet bayonet socket is set in the middle part of set gauge, magnetic sheet is arranged on magnetic sheet bayonet socket place, at magnetic sheet bayonet socket downside, secondary magnet bayonet socket is set, secondary magnet is fixed on secondary magnet bayonet socket, accurate positioning, avoid off normal, be provided with magnetic sheet, substantially stopping the bonding defective products of main magnet and secondary magnet same polarity produces, improve the yield of product, thereby reduce production costs.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, this magnetic circuit structure for loudspeaker is simplified, and volume is little, accurate positioning, and assembling is simple, improves product yield.this magnetic circuit structure for loudspeaker, comprise basin frame 5, set gauge 1, magnetic sheet 2, main magnet 4, secondary magnet 3, described set gauge 1 middle part arranges the magnetic sheet bayonet socket, described magnetic sheet 2 is arranged on magnetic sheet bayonet socket place, described magnetic sheet bayonet socket downside arranges secondary magnet bayonet socket, described secondary magnet 3 is fixed on secondary magnet bayonet socket, described secondary magnet bayonet socket downside arranges main magnet bayonet socket, described set gauge extends magnet faceplate 6 along main magnet bayonet socket sidewall, described main magnet 4 is fixed on basin frame 5 bottoms, described main magnet 4 sidewall bottom the basin frame has the space that adapts with magnet faceplate thickness, described set gauge 1 is by magnet faceplate 6 clamping basin framves 5,
Described set gauge 1 adopts plastic-steel material to make;
Described main magnet 4 upper ends are provided with magnetic pole core;
Described main magnet 4 is opposite with two magnetic pole installation directions of secondary magnet 3, and described secondary magnet 3 is consistent with two magnetic pole installation directions of magnetic sheet 2.
main magnet is fixed on basin frame bottom, bottom main magnet and basin frame, sidewall has the space that adapts with magnet faceplate thickness, set gauge can pass through magnet faceplate clamping basin frame, assemble simpler, the magnetic sheet bayonet socket is set in the middle part of set gauge, magnetic sheet is arranged on magnetic sheet bayonet socket place, at magnetic sheet bayonet socket downside, secondary magnet bayonet socket is set, secondary magnet is fixed on secondary magnet bayonet socket, accurate positioning, avoid off normal, be provided with magnetic sheet, substantially stopping the bonding defective products of main magnet and secondary magnet same polarity produces, as, in the utility model, the N magnetic pole of main magnet is fixed on bottom the basin frame, ndfeb disk and the set gauge of magnetic of substituting the bad for the good glues together, the N magnetic pole of magnetic sheet up, the S magnetic pole down, the secondary magnet of magnetic of first substituting the bad for the good is placed in set gauge, consistent with two magnetic pole installation directions of magnetic sheet, and then set gauge is inserted in the basin frame get final product, realize that namely the polarity of magnetic circuit distinguishes, avoided poor attachment between main magnet and secondary magnet, improve the yield of product, thereby reduce production costs.
The above is only preferred implementation of the present utility model, enable those skilled in the art to understand or realize the utility model, multiple modification to this embodiment will be apparent to one skilled in the art, in the situation that do not break away from spirit or scope of the present utility model, can realize in other embodiments, therefore, the utility model will can not be limited and embodiment illustrated herein, but will meet the wide region consistent with principle disclosed herein and features of novelty.
