摘要： A speaker mount, assembly, and method of disengagement including a flange that circumscribes a perimeter of the mount. The speaker mount includes a support member coupled to the flange. The speaker mount includes a tab moveably coupled to the support member. The speaker mount includes a tab bias member functionally coupled to the tab. The speaker mount includes a path guide functionally coupled to the tab and to the support member. The path guide includes a vertical pathing and a rotational pathing that is substantially orthogonal to the vertical pathing. The speaker mount includes a blocking member functionally coupled to the tab such that in a blocking mode the blocking member obstructs free movement of the tab along the path guide and in a free mode does not obstruct.
