Abstract: A speaker housing assembly including an adapter and a speaker enclosure is disclosed. The adapter has an escutcheon and a partially spherical recessed concave portion. The speaker enclosure has a partially spherical sidewall that is received in the recessed concave portion of the adapter. A lock assembly secures the speaker enclosure to the adapter through an arcuate slot. Flanges of the lock assembly are placed in registry with teeth formed on opposite sides of the arcuate slot to lock the speaker enclosure in place. An elastomeric pad is provided between the recessed concave portion and the partially spherical sidewall to dampen vibrations and supplement the locking engagement of the lock assembly.

A surface mounting adapter has a peripheral edge portion and a planar portion extending between the peripheral edge portion and the enclosure structure. Portions of at least four sides of the enclosure structure protrude from the planar portion of the wall. Other portions of at least four sides of the enclosure structure are recessed relative to the planar portion of the wall.
