Wherein, the magnetic circuit system of loudspeaker can also be other forms, for example, the magnetic circuit system is also included located at described
The center of conductive magnetic yoke is wholely set or conducting magnetic column that split is set with the conductive magnetic yoke, and the conducting magnetic column leads with the side
Magnetic gap is formed between magnetic sheet.
The one embodiment for the loudspeaker provided with reference to Fig. 1-3 explanation the utility model：
The housing that loudspeaker includes protecgulum 1, vibrational system 100, magnetic circuit system, accommodates vibrational system 100 and magnetic circuit system
4.Vibrational system 100 includes vibrating diaphragm 2 and is fixed on the voice coil loudspeaker voice coil 3 of the lower section of vibrating diaphragm 2, and wherein vibrating diaphragm 2 includes vibrating diaphragm body and reinforcement part,
The vibrating diaphragm body includes the central area fixed with the reinforcement part and the ring portion for being arranged at the central area edge.
Magnetic circuit system includes the magnetic conductive board, magnet and the conductive magnetic yoke 7 that are combined together from top to bottom, wherein, magnet includes being arranged at leading
The centring magnet 61 of the center of yoke 7 and the side magnet 62 around centring magnet 61, magnetic conductive board include being arranged at center
The center magnetic conductive board 51 of the upper surface of magnet 61, and around center magnetic conductive board 51, be arranged at while the upper surface of magnet 62 while
Magnetic conductive board 52.Centring magnet 61, the integrative-structure of center magnetic conductive board 51 and while magnet 62, while magnetic conductive board 52 integrative-structure between
Magnetic gap 8 is provided with, voice coil loudspeaker voice coil 3 is arranged in magnetic gap 8.Wherein, while magnetic conductive board 52, while magnet 62 and conductive magnetic yoke 7 and housing 4
It is integrated injection structure.
Wherein, voice coil loudspeaker voice coil 3 includes voice coil loudspeaker voice coil main body and voice coil leads, and voice coil leads can be connected by shell fragment 41 and external circuit
Connect, can by shell fragment 41, while magnetic conductive board 52, while magnet 62 and conductive magnetic yoke 7 and the integrated injection molding of housing 4.
Specifically, it is shown in Figure 3, can first by while magnetic conductive board 52, while magnet 62, conductive magnetic yoke 7 with glue be bonded shape
Into external magnetic circuit component 400.Then by shell fragment 41, housing 4 and the integrated injection molding of external magnetic circuit component 400, one is formed
Injection structure 300.
Shown in Figure 2, Xian Jiang centers magnetic conductive board 51 and the bonding of centring magnet 61 form center magnetic path component 200, then will
Center magnetic path component 200 is adhered to the center of the conductive magnetic yoke 7 of integrated injection molding structure 300, is then installed on magnetic circuit system
Vibrational system 100, finally installs protecgulum 1 in the top of vibrational system 100, and so far loudspeaker assembling is finished.
It should be noted that the term such as " top " of the present utility model, " lower section ", " from top to bottom ", " upper and lower " only table
Show the relative position relation between each part of loudspeaker, therefore when being overturn to loudspeaker or being rotated, this is with respect to position
Relation is put it may happen that reverse or change.
Referring to shown in Fig. 2 and Fig. 3, after integrated injection molding structure 300 is formed, housing 4 by while magnetic conductive board 52 and while magnet 62
All be coated on inside, do not expose completely while magnetic conductive board 52 and while magnet 62, this can make while magnetic conductive board 52 and while magnet 62
Fixed is more firm.Also, in this case, due to while magnetic conductive board 52 and while magnet 62 be coated on by housing 4 completely in,
Therefore while magnetic conductive board 52 and while magnet 62 surface do not need electroplating technology treatment ensure that very strong corrosion resistance, i.e.,
While magnetic conductive board 52 and while magnet 62 surface can be without coating.
As can be seen that conductive magnetic yoke 7 only has outer peripheral portion to be covered by housing 4 from Fig. 1-3.From the centre bit of conductive magnetic yoke 7
Put up to conductive magnetic yoke 7 and the corresponding position of magnetic gap 8, this part of upper and lower surface is exposed to outside housing 4, conductive magnetic yoke
7 with the corresponding position of magnetic gap 8 being provided with stomata 71, this be due to while magnetic conductive board 52, while magnet 62 and conductive magnetic yoke 7 and housing
4 are integrated injection structure, stomata are formed on housing 4 higher to Shooting Technique requirement therefore reserved in conductive magnetic yoke 7 in advance
Venthole 71 is reducing technology difficulty.By conductive magnetic yoke 7 only has part to be covered by housing 4, do not wrapped by housing 4 completely
Cover, therefore the surface of conductive magnetic yoke 7 is still provided with coating.
As can be seen that side magnetic conductive board 62 can be annular from Fig. 2 and Fig. 3, and the periphery of side magnetic conductive board 62 is provided with many
Individual fluting 521, during integrated injection molding, fluting 521 can fill more injected plastics materials so that injected plastics material and side magnetic conduction
Grip between plate 62 is stronger, the integrated injection molding structure 300 for eventually forming more closely, with intensity higher.
Wherein, can be the while magnet of annular in magnet.Or, side magnet can be four, respectively positioned at centring magnet
Surrounding.Or, magnet and the second side magnet when magnet can include first, the relative both sides of conductive magnetic yoke are provided with upward side
Wall, first in magnet and second magnet be respectively arranged at conductive magnetic yoke and there is no the both sides of side wall.
Wherein, the conductive magnetic yoke in Fig. 1-3 is magnetic conductive board, and in other embodiments, the shape of conductive magnetic yoke can be according to tool
Body demand and set, such as conductive magnetic yoke can be bowl-shape.
The loudspeaker that the utility model is provided, side magnetic structure, conductive magnetic yoke and housing are integrated injection structure, and side magnetic
Line structure is all coated on inside by housing, strong therefore, it is possible to strengthen the connection between conductive magnetic yoke and side magnetic structure and housing
Degree, prevents and releases, so as to improve the reliability of speaker product.Wherein, side magnet, side magnetic conductive board is molded in modeling completely
In material shell body, can ensure very strong corrosion-resistant without carrying out electroplating technology treatment, improve the reliability of loudspeaker.And
And, in the case of integrated injection molding, while magnet and while magnetic conductive board between and viscose glue between side magnet and conductive magnetic yoke only
Need to play stationary positioned effect, without considering adhesive strength, therefore less glue amount can be used, so as to thick in loudspeaker
Degree increases effective thickness on direction, strengthens acoustical behavior.
Although being described in detail to some specific embodiments of the present utility model by example, this area
It is to be understood by the skilled artisans that example above is merely to illustrate, rather than in order to limit scope of the present utility model.This
