This Loudspeaker icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,300 icons, all in the same style and quality.
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.
