Jet-bedding, the mode of punching make.
When the magnet yoke device is applied particularly in the moving iron type loud-speaker or receiver, the top of the magnet yoke device
Point bottom surface is fixedly connected with a flat thin magnet respectively with lower part bottom surface；The lower part edge of the magnet yoke device is then used for and armature
It is fixedly connected；The open recess of the upper part side of the magnet yoke device is used as the transaudient of the moving iron type loud-speaker or receiver
Mouthful；And the through hole of the lower part bottom surface of the magnet yoke device is then used as the air pressure balance of the moving iron type loud-speaker or receiver
Mouthful.
Compared with prior art, the advantage of the invention is that：
(1) from structure, moving iron type loud-speaker or receiver are being ensured by the magnet yoke device that upper and lower two parts enclose
On the basis of magnetic circuit, it can also be used as its shell simultaneously, greatly simplifie product structure, not only reduce product cost, it is also prominent
Broken moving iron type loud-speaker or receiver it is intrinsic size limitation, be reduced significantly its appearance and size, widened its application；
(2) from manufacturing process, magnet yoke device manufacturing process derived from the structure design of improvement is simpler, it is low into
This, and the more lossless magnetic property of traditional handicraft is compared, magnetic structure is improved, improves properties of product.

Embodiment
Technical scheme is further described below in conjunction with accompanying drawing and a preferred embodiment.
Refering to Fig. 3-5, the present embodiment is related to a kind of magnet yoke device B1 for being used for moving iron type loud-speaker or receiver, the magnetic
Yoke device B1 is two-piece type structure, including upper part A1, lower part A2 composition；The magnet yoke device B1 upper parts A1 is a four sides
Half box structure enclosed, open recess A3 is equipped with a side of the upper part；The magnet yoke device B1 lower parts
Half box structure that A2 also encloses for a four sides, through hole A4 is equipped with the bottom surface of the lower part A2.
When in use, the magnet yoke device B1 upper parts A1 is alignd and is fixedly connected by edge with lower part A2, before formation
Hold the magnet yoke device B1 enclosed.In the present embodiment, magnet yoke device B1 upper part A1 and lower part A2 combination are sharp
Photocoagulation, and using laser beam by after upper part A1 and lower part A2 bonding crack melting through being cooled into being fixedly connected, in addition,
