Definitions
- the key component of the moving iron headphones is the moving iron unit.
- the moving iron unit is generated by electromagnetic energy conversion, that is, the moving iron unit is a sound transducer.
- the electromagnetic conduction generated by the electromagnetic coil is given to the balance armature, and the magnets on both sides of the balance armature drive the balance armature under the action of the magnetic force.
- the alternating current signal is strong or weak, the balance armature is balanced.
- the shielding case of the current moving iron unit is divided into a lower case and an upper cover (see FIG. 2), and the interface between the lower case and the upper cover has the same structural size, and the abutting surface is flat, and the butt joint is welded or Glue to fix the connection. Since the interfaces of the upper and lower casings have the same structural dimensions and are flat, when the butt joints are connected, the upper and lower casings are difficult to locate, and slight attention will result in positional deviation of the interface, which affects the appearance quality. Moreover, with this structure, the upper and lower casings can only be made of a metal material, otherwise welding cannot be performed. Moreover, it is difficult to weld at the interface, and the welding operation precision is very high, so the processing quality is difficult to guarantee.
- the application relates to a moving iron unit for a speaker device, comprising a shielding shell, a balance armature, a magnet, an electromagnetic coil, a diaphragm, a wire, and a sound guiding tube located in the shielding shell.
- the shielding case is divided into an upper case and a lower case, and the upper case and the lower case are sealedly connected by a nesting manner.
- a shielding case for a moving iron unit for a speaker comprising an upper casing and a lower casing, wherein the upper casing and the lower casing are both bent " ⁇ " structures, and The upper casing and the lower casing pair are inserted to form an accommodation space for placing the moving iron unit.
- connection between the upper casing and the lower casing is adhesively connected.
- connection between the upper casing and the lower casing is connected by welding and adhesive bonding.
- the material of the upper casing may be metal or plastic; the material of the lower casing may be metal or plastic.
- a shield case for a moving iron unit for a speaker of the present invention wherein the upper case and the lower case are both bent " ⁇ " structures, and the upper case and the lower case pair
- the plugging forms a accommodating space for placing the moving iron unit, which is convenient to process, can realize automatic production, saves time and labor, and has high production efficiency;
- FIG. 2 is a schematic structural view of a shield case for a moving iron unit for a speaker according to the prior art.
- the reference numerals in the schematic diagram indicate: 1, the upper casing; 2, the lower casing; 21, the sound guiding hole; 22, the groove.
- a shield housing for a moving iron unit for a speaker of the present embodiment includes an upper housing 1 and a lower housing 2, both of which are bent twice. ⁇ " structure, and the upper casing 1 and the lower casing 2 form a accommodating space for placing the moving iron unit on the plug-in enclosure, which is convenient to process, can realize automatic production, saves time and labor, and has high production efficiency; a sound guiding hole 21 facing the sound hole of the moving iron unit is opened on one side wall, and a groove 22 for placing a wire is opened on the upper edge of the other side wall of the lower case 2, and the lower case 2 is folded Before the bending, the processing has been completed on the lower casing 2, and the processing is convenient, and the secondary processing technology is omitted; in the embodiment, the upper casing 1 is made of metal or plastic, and the lower casing 2 is made of metal or plastic. In this embodiment, the connection between the upper casing 1 and the lower casing 2 is welded.
- the basic structure of the shield case for a moving iron unit for a speaker of the present embodiment is the same as that of Embodiment 1, except that the joint of the upper case 1 and the lower case 2 is adhesively bonded.
- the sound guiding hole 21 and the groove 22 are processed on the lower case 2 which is not bent, and the lower case 2 is twice bent into a " ⁇ " structure, at which time the sound guiding hole 21 is disposed opposite to the lower case.
- the sound hole of the moving iron unit in 2, the groove 22 can pass the wire of the moving iron unit; the upper casing 1 is bent into a " ⁇ " structure twice, and the lower casing 2 is formed by the plug-in enclosure
- the accommodating space of the moving iron unit can be placed, the processing is convenient, the secondary processing technology is omitted, the time and labor are saved, and the production efficiency is high.
- the utility model relates to a shielding shell for a moving iron unit of a speaker, which is convenient in processing and assembly, saves time and labor, and has high production efficiency.
