Idea of Loudspeaker Icon
It's a rectangle with 2 circles in it with another circle like image with it. On the outside of the two circles there are 4 dots in each corner of the rectangle. As you get closer to the circles, they both overlap each other basically right next to each other. In that are forming a bunch of dots all around the circumference of the circle. This is where the inner most circle is where the "music" comes from.
This Loudspeaker icon has Android KitKat style
. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
