Further, during the upper and lower two parts combination of described yoke device, by edge, align and be fixedly connected with, described yoke device front end is enclosed.
The upper part of described yoke device is that resistance welded, laser welding, ultrasonic bonding or adhesive are bonding with the compound mode of lower part.
Described yoke device is manufactured with soft iron, A3 steel, permalloy or Ferrite Material on material.
The upper part of described yoke device adopts one-step punching forming to enclose structure with lower part on manufacturing process, and the mode of secondary jet-bedding, punching is made.
When described yoke device specifically is applied in described moving iron type loud-speaker or receiver, the upper part bottom surface of described yoke device is fixedly connected with a flat thin magnet respectively with lower part bottom surface; The lower part edge of described yoke device is for being fixedly connected with armature; The open recess of the upper part side of described yoke device is as the speaking terminal of described moving iron type loud-speaker or receiver; The through hole of the lower part bottom surface of described yoke device is used as the air pressure balance mouth of described moving iron type loud-speaker or receiver.
Compared with prior art, the invention has the advantages that:
(1) from structure, the yoke device enclosed by upper and lower two parts is on the basis that guarantees moving iron type loud-speaker or receiver magnetic circuit, also can be used as its shell simultaneously, 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), manufacturing process, the derivative yoke device manufacturing process of the structural design of improvement is simpler, low-cost, and compares the more harmless magnetic property of traditional handicraft, has improved magnetic structure, has promoted properties of product.
