Loudspeaker of loudspeaker box

Abstract

The invention relates to the technical field of loudspeaker boxes, in particular to a loudspeaker 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 loudspeaker 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. 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 the dust cover, the damper in the prior art loudspeaker is an annular corrugated plate, but its corrugation width is the same as the height, but because the radius of each circle in the damper is different, so cause Without it, the outer ring has a larger surface area than...

[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 the dust cover, the damper in the prior art loudspeaker is an annular corrugated plate, but its corrugation width is the same as the height, but because the radius of each circle in the damper is different, so cause Without it, the outer ring has a larger surface area than the inner ring, and the stress on the outer ring is also greater, resulting in distortion of the speaker using this damper; and the preparation of the damper in the prior art is usually It is prepared by hot pressing technology, but when using this kind of hot pressing industry 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 hot brittleness, and the glue after high temperature It is easy to be powdered and distributed unevenly on the material, making the air permeability of the damper poor, which in turn leads to the poor effect of the speaker installed with the damper prepared by this process
