Embodiment Construction

[0016] Aiming at the technical solution proposed above, a preferred embodiment is given and described in detail with reference to the drawings. see figure 1 , figure 2 , the moving iron unit of the present invention includes a shielding shell, a magnet, an electromagnetic coil, and a balanced armature, wherein:

[0017] The shielding case includes an upper case 1 and a lower case 2, which can be made of metal or plastic. A limit platform 21 is provided on the inner side wall of the docking port of the lower case 2 , and the docking plane of one side 22 of the lower case 2 where the sound guide tube 8 is installed is flush with the limit platform 21 . On the outer side wall of one side 22 of the lower housing 2, a limiting slot 23 for limiting the position of the sound guide tube 3 is opened. The shape of the upper casing 1 meets the requirement that it just snaps into the limiting platform 21 . During assembly, the upper casing 1 is just stuck on the limiting platform 21 ...

Abstract

The invention provides a moving iron unit for a loudspeaker. The moving iron unit comprises a shielding housing, a balance armature, a magnet, an electromagnetic coil, a vibrating membrane, a lead, and a voice guide pipe, wherein the balance armature, the magnet, the electromagnetic coil, the vibrating membrane, the lead and the voice guide pipe are placed in the shielding housing; and the moving iron unit is characterized in that the shielding housing is divided into an upper housing and a lower housing which are connected in a manner of embedding. According to the moving iron unit for the loudspeaker, the upper housing and the lower housing are abutted by embedding, so that the precision in abutting of the upper housing and the lower housing is reduced, and the working efficiency is improved. The upper housing and the lower housing are made of plastic and can be manufactured in an injection molding way. Compared with the metal materials, when plastic injection molding is carried out to manufacture the upper housing and the lower housing, the cost is lowered, and the processing technology is simple. The welding process can be avoided due to the use of the plastic housings.

Description

technical field [0001] The invention relates to a sounding unit used for loudspeakers, loudspeakers, earphones, etc., especially a moving iron sounding unit. Background technique [0002] Moving iron earphones are mid-to-high-end products currently on the market. The key components of moving iron earphones are moving iron units. For moving coil earphones, they have more stable frequency response curves, higher sensitivity, deep ear penetration, and low resistance. It has gradually been accepted and valued by music lovers who pay attention to sound quality. The principle of the moving iron unit is electromagnetic energy conversion, that is, the moving iron unit is a sound transducer. By transmitting the sound to the electromagnetic coil in the form of an alternating current signal, the electromagnetic generated by the electromagnetic coil is transmitted to the balanced armature, and the magnets located on both sides of the balanced armature drive the balanced armature to mov...
