As seen from Figure 4, in the present embodiment, two side magnetic poles 51, 52 the N utmost point upward, its magnetic line of force is delivered on the second magnetic conduction washer 72 by the first magnetic conduction washer 71 of upper surface separately, realize the magnetic line of force and transfer the concentrated conduction of horizontal direction to by vertical direction, the lower surface of the second magnetic conduction washer 72 is close to the S utmost point of centring magnet 6, and the magnetic line of force is conducted to centring magnet 6, the N utmost point of centring magnet 6 conducts to the magnetic line of force by magnetic conductor bowl 11 the S utmost point of two blocks of side magnetic stripes of voice coil loudspeaker voice coil both sides, two magnet loop in Fig. 2 have been formed thus, visible, in whole magnet loop, only having the sidewall that the first magnetic conduction washer is relative with the second magnetic conduction washer is to open wide to form groove, be used to voice coil loudspeaker voice coil up-down vibration that space is provided, and other sections of magnet loop are all the conducted inside at magnet inside or magnetic conductive part, make the magnetic line of force in magnet loop conduct comparatively concentrated, reduced magnetic dispersion, strengthened the magnetic field intensity being subject in voice coil loudspeaker voice coil horizontal direction.
In order further to promote the magnetic field intensity of magnetic devices, in addition relative both sides in the present embodiment outside voice coil loudspeaker voice coil 3 are respectively equipped with the another two block side magnetic stripes 53 identical with described two side magnetic stripe pole orientation, described another two side side slat 53 upper surfaces are respectively equipped with the 3rd magnetic conduction washer 73, the magnetic line of force between the first magnetic conduction washer 71 sidewall relative with the 3rd magnetic conduction washer 73 between Delivery Center magnet 6 and described another two blocks of side magnetic stripes 53, concrete magnet loop forms principle and above-mentioned two blocks of side magnetic stripes 51, it is identical that 52 magnet loop that form with centring magnet 6 form principle, repeat no more herein.
Visible, in the present embodiment, take voice coil loudspeaker voice coil 3 as benchmark, at surrounding and the medium position of voice coil loudspeaker voice coil 3, be all provided with magnetic stripe or magnet, strengthen magnetic field intensity, the magnetic sheet that in the present embodiment, centring magnet 6 matches for outline and voice coil loudspeaker voice coil; The side magnetic stripe voice coil loudspeaker voice coil length of side coupling corresponding with this side magnetic stripe outside voice coil loudspeaker voice coil 3, in the present embodiment, voice coil loudspeaker voice coil is rectangular coil, voice coil loudspeaker voice coil inside casing is also rectangle, 6 magnetic sheets that are designed to rectangular profile of centring magnet, to guarantee that in magnet loop, the magnetic line of force is conducted by this magnetic sheet, reduce magnetic dispersion, correspondingly, the length of each side magnetic stripe also matches with each length of side of this rectangular coil, equates with the length of side of rectangular coil inside casing or quite.
Certainly; the radiator of employing rectangular coil is fit to do the structure of orthogonal plate; if and will manufacture the radiator of circular slab structure; can adapted circular voice coil loudspeaker voice coil; therefore side magnetic stripe is made arcuate structure accordingly, is only that the simple deformation of doing in shape at radiator or voice coil loudspeaker voice coil must belong to protection range of the present utility model.
In order to guarantee the stability to voice coil loudspeaker voice coil power supply, in the present embodiment, thermal conductive cavity madial wall is fixed with a metal clips 8 extending outside thermal conductive cavity 1, and the terminals of voice coil loudspeaker voice coil 3 are electrically connected to this metal clips 8.Particularly, this metal clips adopts rectangular sheet metal, sidewall at sheet metal extends fixed part, in manufacturing process, on thermal conductive cavity madial wall, there is the fixed leg corresponding with this fixed part, be that magnetic conductor bowl and cap are provided with fixed leg opposing upper and lower, the fixed part of sheet metal is fixedly clamped, guarantee that sheet metal is not because vibration occurs to depart from or become flexible.
Embodiment 2:
In order further to reduce the body vibration of oscillatory type radiator, the utility model embodiment makes improvement on the basis of above-described embodiment 1, a kind of damping ultrathin radiator is provided, be included in and take on the whole a plurality of above-mentioned ultrathin loudspeaker formula radiator that center line is symmetry axis symmetry arrangement, the ultrathin loudspeaker formula radiator of symmetry axis both sides has contrary vibration phase, and a plurality of described ultrathin loudspeaker formula radiators are arranged on a support.
As shown in Figure 5, the damping ultrathin radiator that two the ultrathin loudspeaker formula radiators of take form is example, ultrathin loudspeaker formula radiator 10 and ultrathin loudspeaker formula radiator 20 be arranged evenly becomes axially symmetric structure, this support 30 has two unit fixed mounts, for fixedly ultrathin loudspeaker formula radiator 10 and ultrathin loudspeaker formula radiator 20 respectively, support is the support with axially symmetric structure.
For damping ultrathin radiator in the present embodiment being quickly installed on the equipment of corresponding size, support 30 described in the utility model embodiment is spliced by sidewall by a plurality of unit fixed mounts 31 for fixing described ultrathin loudspeaker formula radiator, the sidewall of adjacent unit fixed mount has detachable syndeton, can be for example the fit structure really up to the mark of projection and groove, can be the fixed structure by bolts and nuts.
According to the quantity of ultrathin loudspeaker formula radiator, determine symmetry axis position, for even number ultrathin loudspeaker formula radiator, symmetry axis both sides have the ultrathin loudspeaker formula radiator of equal number, in the voice coil loudspeaker voice coil of the ultrathin loudspeaker formula radiator of symmetry axis both sides, pass into rightabout electric current, make voice coil loudspeaker voice coil vibration phase contrary, the ultrathin loudspeaker formula radiator of symmetry axis both sides has contrary momentum, the aggregated momentum of whole damping ultrathin radiator reduces, for the radiator of minimum vibration provides architecture basics.Be appreciated that, when the damping ultrathin radiator of odd number ultrathin loudspeaker formula radiator formation, on the center line of the ultrathin loudspeaker formula radiator in the middle of symmetry axis drops on, the vibration phase of the ultrathin loudspeaker formula radiator of middle ultrathin loudspeaker formula radiator and its both sides can be relatively independent.
