Below in conjunction with accompanying drawing magnetic speaker of the present utility model is described.
See also Fig. 1 to Fig. 5, wherein, Fig. 1 is the stereochemical structure decomposing schematic representation of the utility model magnetic speaker one better embodiment, Fig. 2 is the voice coil loudspeaker voice coil of magnetic speaker shown in Figure 1 and the perspective view after the assembling of ball top, Fig. 3 is the voice coil loudspeaker voice coil of magnetic speaker shown in Figure 2 and the plan structure schematic diagram after the assembling of ball top, Fig. 4 is the perspective view after the magnetic speaker assembling shown in Figure 1, and Fig. 5 is the side cross-sectional schematic of magnetic speaker shown in Figure 4.This magnetic speaker 2 comprises ball top 20, ring 21, centring disk 22, magnetic conduction sheet 23, magnet steel 24, voice coil loudspeaker voice coil 25, magnetic bowl 26 and basin frame 27.
This basin frame 27 is one to adopt the support body of the tool receiving space (indicating) that plastics make, this receiving space both ends open.This basin frame 27 forms a step 270 in this receiving space, this step 270 is divided into two parts up and down with this receiving space.
This centring disk 22 is elastic plates, and its integral body is hollow ring, and this annular section is provided with pierced pattern, to allow airflow.The outline of this centring disk 22 is corresponding with these step 270 edges of this basin frame 27.
This ring 21 is circuluses, and the outer ledge of this circulus is corresponding to the outline of this centring disk 22, and this circulus is bonding by adhesive and this centring disk 22.
This ball top 20 is positioned at the zone line of this ring 21, and cooperates with this ring 21 and to surround a lid, and centring disk 22 fixed supports by bonding together with it simultaneously form the vibrational system of this magnetic speaker 2 of composition.This ball top 20 comprises many ribs 202, and this ribs 202 is for hard material makes, and such as metal, these many ribs 202 are parallel to each other and push up 20 surfaces across being arranged at this ball.Further, four corners on this ball top 20 are chamfering structure.
This magnetic bowl 26 is housed in the lower part of the receiving space of this basin frame 27, it comprises diapire 260 and a plurality of sidewall 262, and this diapire 260 is provided with through hole in the position in the middle, in the present embodiment, this diapire 260 comprises two through holes, and the line of this two through hole is perpendicular to the long limit of this diapire 260.These a plurality of sidewalls 262 extend upward from the edge of this diapire 260, thereby form another receiving space (not indicating) with this diapire 260.Wherein, between this sidewall 262 on this diapire 260 long limits and this sidewall 262, do not connect mutually, that is to say that four corners of this magnetic bowl 26 include opening at these diapire 260 minor faces.
These magnet steel 24 and these magnetic conduction sheet 23 superimposed settings, and corresponding being contained in the receiving space of this magnetic bowl 26, this magnet steel 24 is sandwiched between the diapire 260 and this magnetic conduction sheet 23 of this magnetic bowl 26.
