Loudspeaker unit of loudspeaker box

Abstract

The invention relates to the technical field of loudspeaker boxes, in particular to a loudspeaker unit of a loudspeaker box. The ripple height and width of a centring disk in the loudspeaker are decreased along with the increasement of the radius, and the centring disk is prepared by adopting a cold pressing technology; the outer surface of the cambered surface of a dust cover is fixed on a voice coil support, and the orientation of the dust cover is the same as that of a vibrating diaphragm. The loudspeaker unit of the loudspeaker box is less in distortion and better in effect.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a sound box speaker unit. 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] Speaker speaker is an important part of the speaker, it mainly includes the lower magnetic plate, upper magnetic plate, magnetic core column, permanent magnet, voice coil, voice coil bracket, centering piece, diaphragm, basin frame, ring and 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 a larger surface area than the i...

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] And the dust cover of the prior art is generally fixed on the diaphragm, so when the speaker is working, it will affect the mid-high frequency characteristics of the diaphragm
