Abstract
A speaker frame, and corresponding speaker, may have tapered spokes that form a radial triangular pattern with an apex converging near the frame's mounting flange, for example, near tabs including mounting holes where the frame attaches to a speaker baffle. The tapered spokes may include a triangular cut-out region defining a pair of converging legs that converge at the mounting flange. The width, curvature, and the angle of the spokes may allow for a thin and lightweight configuration with uniformly distributed minimal stress.
