Embodiment Construction

[0029] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate orientation or positional relationship Based on the orientation or positional relationship shown in the drawings, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the referred device o...

Abstract

Embodiments relate to the design field of moving iron, and particularly relate to a magnet armature band and a preparation method therefor. The preparation method for the magnet armature band comprises the steps of manufacturing a yoke iron assembly, wherein the yoke iron assembly comprises a material band and multiple pieces of first yoke iron; each first yoke iron is connected to the material band separately; welding a first magnet with each first yoke iron to obtain a yoke magnetic assembly; performing welding and fixing on a second magnet and a second yoke iron to obtain a yoke body assembly; and performing welding and fixing on the yoke magnetic assembly and the yoke body assembly to obtain the magnet armature band, wherein one yoke magnetic assembly and the corresponding yoke body assembly welded therewith form a magnet armature unit. By virtue of the technical scheme, the yield of the magnet armature unit can be realized.

Description

【Technical field】 [0001] The embodiments of the present invention relate to the field of moving iron design, in particular to a method for preparing a magnet armature band and the magnet armature band. 【Background technique】 [0002] In the moving iron unit, the magnet armature is a very important part of the entire magnetic circuit. The ability of the magnet to magnetize determines the upper limit of the sound pressure output, and the magnetic permeability of the yoke determines the distortion and reliability of the moving iron unit. Performance, in the traditional magnet armature unit assembly process, the yoke is designed as a closed loop structure, mainly by artificial means, the magnet is placed inside the closed yoke, and the inner surface of the yoke is attached, and It is necessary to ensure that the fit is tight. At the same time, the magnet must be completely placed inside the yoke and cannot protrude. [0003] In the process of realizing the present invention, th...
