Abstract
An electro-dynamic loudspeaker includes a frame, a magnet and a diaphragm. The frame includes a body portion defining a magnet mounting surface as well as a plurality of protrusions extending from the magnet mounting surface. The magnet is magnetically attracted to the body portion of the frame. The magnet is restricted from movement along the magnet mounting surface by at least one protrusion. The diaphragm is spaced apart from the magnet and coupled to the frame.
