Loudspeaker

Abstract

The invention relates to the technical field of sound boxes and in particular relates to a loudspeaker. With the increase of radius, the corrugation height and width of a centering disk in the loudspeaker are reduced; in addition, the centering disk is prepared through a cold pressing process, and the inner end of a voice coil support is chamfered; besides, a layer of lubricating oil is applied to the inner circle of the voice coil support; such a loudspeaker is relatively low in distortion and good in effect.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a loudspeaker. Background technique [0002] The speaker is the last and most important component in the entire audio system process. Its playback quality has a great impact on the performance of the entire system. According to professional estimates, the contribution of speakers to the entire audio system accounts for more than 30% of the entire system. [0003] The loudspeaker is an important part of the speaker, which mainly includes the lower magnetic plate, the upper magnetic plate, the magnetic core column, the permanent magnet, the voice coil, the voice coil bracket, the centering piece, the diaphragm, the basin frame, the ring and the Dust cover. [0004] The strut in the prior art loudspeaker is an annular corrugated plate, but its corrugated width is the same as the height, but because the radius of each circle in the strut is different, so its outer ring is With ...

AI Technical Summary

Problems solved by technology

[0004] The strut in the prior art loudspeaker is an annular corrugated plate, but its corrugated width is the same as the height, but because the radius of each circle in the strut is different, so its outer ring is With a larger surface area than the inner ring, the outer ring bears greater stress, which leads to distortion of the speaker using this damper; and the prior art damper is usually prepared by hot pressing Yes, but when this kind of hot pressing industry is used to produce the support piece, the high-temperature molding temperature is usually above 200°C, which will cause great damage to the material, and the finished product is prone to thermal brittleness, and the glue after high temperature is easy to become powdery. Evenly distributed on the material, the air permeability of the damper is poor, which leads to the poor effect of the speaker installed with the damper prepared by this process

[0005] Moreover, in the production process of the prior art voice coil support, some inwardly bent burrs will be produced, so that after the voice coil support is installed, friction will occur with the magnetic core post, which will cause distortion in the speaker using this voice coil support.
