Embodiment
For the loadspeaker structure of the utility model embodiment is described in detail, below with reference to accompanying drawing to tool of the present utility model
Body embodiment is described in detail.
Fig. 1 shows the cross-section structure of the loudspeaker according to the utility model embodiment；Fig. 2 shows new according to this practicality
The structure of the conductive magnetic yoke of type embodiment；Fig. 3 and Fig. 4 show raising one's voice according to the utility model embodiment from different perspectives respectively
The structure of device.
It is common shown as shown in Figure 1 to Figure 4, the loudspeaker of the utility model embodiment, including magnetic circuit system；Wherein, magnetic circuit system
System further comprises conductive magnetic yoke 4, the magnet being housed in successively in conductive magnetic yoke 46 and washer 5, to ensure that magnet 6 is located at conductive magnetic yoke 4
Center, and simplify magnet 6 packaging technology, in conductive magnetic yoke 4 set be adapted with the size and structure of magnet 6 sinks
Groove 7, washer 5 is fixed on side of the magnet 6 away from conductive magnetic yoke 4, and the magnet 6 for being fixed with washer 5 it is spacing be fixed on it is corresponding heavy
In groove 7.
Wherein, the size of deep gouge 7 is not less than the sectional dimension of magnet 6, can be set to be slightly larger than or equal to magnetic
The sectional dimension of iron 6, in the assembling process of magnetic circuit system, regard the fixed magnet 6 completed and washer 5 as entirety and conductive magnetic yoke
4 are fixed, in the presence of deep gouge 7, can not only auxiliary magnet 6 assembling, save magnet positioning tool, improve assembling effect
Rate, additionally it is possible to ensure the concentricity of magnet 6, washer 5 and conductive magnetic yoke 4, assembly precision is high, good product performance.
Further, magnet 6 is fixed in deep gouge 7 by gluing, preferably magnet 6 can be positioned, be prevented it
Come off in use from conductive magnetic yoke 4.
The loudspeaker of the utility model embodiment, in addition to the vibrational system with magnetic circuit system cooperation sounding；Vibrational system
Including vibrating diaphragm 2 and the voice coil loudspeaker voice coil 3 for being pasted and fixed on the side of vibrating diaphragm 2.Wherein, vibrating diaphragm 2 is circular configuration, including is fixed with conductive magnetic yoke 4
The fixed part outermost of vibrating diaphragm (be located at) of connection, the ring portion for the male female structure being wholely set with fixed part and it is arranged on
Planar portions (penetralia for being located at vibrating diaphragm) inside ring portion, reinforcement part is arranged on the planar portions of vibrating diaphragm, is mainly used in adjusting loudspeaker
The acoustical behavior of monomer, to reduce the oeverall quality of vibrational system, generally sets in the position of planar portions correspondence reinforcement part and goes
Material, reinforcement part is then covered in the feeding position.
