冲压扬声器网罩与网孔面板

扬声器网罩本质上是一道冲孔工序:一次冲压行程冲出数百个孔,开孔率与声学设计相匹配。我们采用冷轧钢、不锈钢或铝材冲压网罩与网孔面板,料厚0.5至2.0 mm。

冲孔模具按您指定的孔径与孔距制作,孔形可为圆孔、六角孔或长圆孔。面板出模后保持平整,用螺钉固定到箱体上时不会出现鼓面现象,孔边毛刺高度控制在0.05 mm以内。

典型规格

材料冷轧钢、不锈钢304、铝5052 / 6061
料厚0.5至2.0 mm
孔型圆孔、六角孔或长圆孔,按图纸定制
开孔率通常为30%至60%
平整度每100 mm范围内不超过0.3 mm
表面处理粉末喷涂、阳极氧化或本色

常见问题

粉末喷涂会堵住孔吗?

不会。涂层厚度为60至90微米,样品在喷涂前后都会测量孔径。如果开孔尺寸必须保持精确,也可以对网面区域做遮蔽处理。

能否匹配现有箱体的螺钉孔位?

可以。请提供箱体图纸或样件面板;安装孔与沉孔角度会直接做进模具,替换网罩即可直接装配。

低音炮网罩的开孔率应取多少?

低音炮通常采用45%至60%的开孔率,并选用较厚的料厚,以避免网面产生共振异响。告知我们喇叭单元尺寸,我们会匹配相应的孔型。

网罩在户外会生锈吗?

户外使用建议采用不锈钢304或经阳极氧化处理的铝材冲压。冷轧钢仅推荐用于室内干燥环境。
