Idea of Badminton Icon
This looks like a circle with several lines in the center of it, forming a grid. There's a line extending from the bottom left of the circle, connecting to a rectangle. There's a trapezoid floating to the left of the circle, with a tiny circle connected to the top of the trapezoid.
