A speaker, having a diaphragm with a central opening and further having a pole piece, including a first sound dispersion element extending from the pole piece through the central opening of the diaphragm and further extending beyond the diaphragm wherein the first sound dispersion element has a larger transverse perimeter distal the pole piece than proximal the pole piece; and no support structures for the first sound dispersion element are located radially external to said first sound dispersion element. The speaker may be integrated with a lamp using a support structure. A second sound dispersion element may be used. A rod, used as a conduit, coupling, and/or support, may extend coaxially with the first sound dispersion element, interior thereto, and to a point beyond the diaphragm. The audio signal for the speaker may be supplied by a wireless link. The speaker and lamp may be configured for a ceiling fan.
