Loudspeaker of sound box

Abstract

The invention relates to the technical field of a sound box, and particularly to a loudspeaker of a sound box. The ripple height and width of a centring disk in the loudspeaker reduce along with increase of a radius. Furthermore the centring disk is prepared according to a cold pressing process. A diaphragm is prepared by a plurality of slurries. A DLC film is further plated outside the diaphragm. The loudspeaker of the sound box has advantages of relatively small distortion, relatively high limit bearing power and relatively good effect.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a sound box speaker. 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 inner ...

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 vibrating membrane in the loudspeaker of the prior art generally only adopts a kind of slurry to make, so performances such as air permeability and sizing degree are all relatively poor, and then make the performance of the loudspeaker that adopts this vibrating membrane poor; And because prior art The strength of the diaphragm is low, so the limit power of the speaker using this diaphragm is low
