Abstract
The utility model relates to a horn of a silicon steel iron core. Most of movable iron cores and static iron cores used on vehicle horns are low-carbon steel, and magnetic loss of the movable iron cores and static iron cores are large, so relatively large current is needed to generate electromagnetic forces driving a coil X, thereby bringing greatly load on a circuit board, so life of the horn is reduced. The horn comprises a static iron core (4) of silicon steel. The static iron core is riveted with a housing assembly (3). The static iron core is inserted into a drive coil (5). The drive coil is disposed in a recess portion of the housing assembly. A lower part of a movable iron core (1) of the silicon steel is inserted into the drive coil. The movable iron core is riveted with a membrane assembly (6). The housing assembly and the membrane assembly are riveted through a gland (2). The utility model is used for the horn in vehicles.
Description
technical field:
the utility model relates to a kind of loudspeaker of silicon steel core.
background technology:
at present, the moving iron core and the static iron core great majority that on car horn, use are mild carbon steel, wherein moving iron core and diaphragm unit riveted joint, static iron core and housing unit riveted joint, be riveted on one by gland between housing unit and diaphragm unit again, forms speaker body, if now the magnetic loss of moving iron core and static iron core is bigger than normal, need so to produce with larger electric current the electromagnetic force of drive coil X, brought very large load to circuit board, cause the loudspeaker life-span to reduce.
summary of the invention:
the purpose of this utility model is to provide a kind of loudspeaker of silicon steel core.
the purpose of this utility model is achieved in that
the loudspeaker of silicon steel core, its composition comprises: the static iron core of silicon steel, described static iron core and housing unit riveted joint, in the insertion drive coil of described static iron core, described drive coil is arranged on the recess in described housing unit, the moving mandrel lower of silicon steel is inserted in described drive coil, and described moving iron core and diaphragm unit riveted joint, rivet by gland between described housing unit and described diaphragm unit.
beneficial effect:
1. the dynamic and static iron core magnetic flux that this material is made is large, magnetic loss is little, under equal conditions, only need less electric current just can drive moving iron core to move back and forth, in reducing circuit load, can also reduce the cost of circuit part components and parts, and can also reduce the heat producing due to electric current, increase the reliability of components and parts, make loudspeaker with and circuit part working stability.Brief description of the drawings:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is the structural representation of iron core.
accompanying drawing 3 is structural representations of static iron core.
embodiment:
embodiment 1:
a kind of loudspeaker of applying silicon Steel material, its composition comprises: the static iron core 4 of silicon steel, described static iron core and housing unit 3 are riveted, in the insertion drive coil 5 of described static iron core, described drive coil is arranged on the recess in described housing unit, insert in described drive coil moving iron core 1 bottom of silicon steel, and described moving iron core and diaphragm unit 6 are riveted, and between described housing unit and described diaphragm unit, rivet by gland 2.
embodiment 2:
according to the loudspeaker of the applying silicon Steel material described in embodiment 1, described moving iron core and described static iron core use silicon steel material cold-heading processing and fabricating to form.
Claims (1)
1. the loudspeaker of a silicon steel core, its composition comprises: the static iron core of silicon steel, it is characterized in that: described static iron core and housing unit riveted joint, in the insertion drive coil of described static iron core, described drive coil is arranged on the recess in described housing unit, the moving mandrel lower of silicon steel is inserted in described drive coil, and described moving iron core and diaphragm unit riveted joint, rivet by gland between described housing unit and described diaphragm unit.
