Further, said yoke device is pressed the edge alignment and is fixedly connected when two parts make up up and down, said yoke device front end is surrounded.
The top of said yoke device and the compound mode of lower part are that resistance welded, laser welding, ultrasonic bonding or adhesive are bonding.
Said yoke device uses soft iron, A3 steel, permalloy or Ferrite Material to make on material.
The top of said yoke device and lower part adopt one-step punching forming to surround structure on manufacturing process, and the mode of secondary jet-bedding, punching is made.
When said yoke device specifically was applied in said moving iron type loud-speaker or the receiver, the bottom surface, top of said yoke device was fixedly connected with a flat thin magnet respectively with the bottom surface, lower part; Said yoke apparatus lower part edge then is used for being fixedly connected with armature; The open recess of the side, top of said yoke device is as the speaking terminal of said moving iron type loud-speaker or receiver; The through hole of said yoke apparatus lower part bottom surface then is used as the air pressure balance mouth of said moving iron type loud-speaker or receiver.
Compared with prior art, the advantage of the utility model is:
(1) from structure; The yoke device that is surrounded by two parts up and down also can be used as its shell simultaneously on the basis that guarantees moving iron type loud-speaker or receiver magnetic circuit, greatly simplified product structure; Not only reduced product cost; Also break through the intrinsic size restrictions of moving iron type loud-speaker or receiver, significantly dwindled its overall dimension, widened its range of application;
(2) in view of manufacturing process, the yoke device manufacturing process that improved structural design is derived is simpler, low-cost, and compares the more harmless magnetic property of traditional handicraft, has improved magnetic structure, has promoted properties of product.
