After rasterizing the shape, I lock off the transparency and duplicate the layer.

在勾扩完外形后，我给透明层解锁，然后拷贝这个层。

Now to give it a little punch, duplicate that layer, set its Opacity to 68%, and apply the following Curves (Command + m) to its transparency mask and you get this.

现在，给数码音量图添加一些视觉刺激。复制图层，设置不透明度为68%，并且对透明图层应用下图曲线(COMMAND + M)。然后，你得到了这个。
