Abstract: A floating sound system for use in a swimming pool or the like has a radio, tape player, power supply, and controls. The power supply unit nests within a toroidal float, being attached thereto by straps. The radio and associated components are located in a domed housing resting upon the float. The sound system is built to disassemble into these three subassemblies. The resultant sound system floats stably in water, and, due to speaker cones arranged parallel to the water surface, projects sound very effectively.

Abstract: A radio frequency receiving device which is totally self contained and is fully supported at a diverging opening of a user's ear extending from the ear canal. The device includes an elongate casement having a lower portion and an upper portion at a total length of less than two inches. The casement is constructed of a top portion and a bottom portion, the top portion being deflected from the bottom portion by an acute angle whose value is between the range of 10 to 30 degrees. The bottom portion includes a speaker device mounted at a proximal side thereof and being configured to frictionally fit at the diverging ear opening in close proximity to the skull, with the upper half resting against the ear or being in frictional contact with an upper lip of the ear extending from the top cartilage.

Abstract: A retrofit bracket for wall mount speakers has a support surface configured for mounting at least one speaker thereto and a pair of elongate clamping bars extending across to opposite sides of the rear of the support surface and adjustably attach thereto such that a wall covering is clampably capturable intermediate the support surface and the bars. An adjustment means facilitates varying of the distance between the support surface and the bars to accommodate various wall covering thicknesses. The elongate bars are sufficiently flexible to provide spring tension against the wall covering captured intermediate the bars and the support surface. A foot is formed upon each end of the elongate bars for distributing the force applied by the bars over an increased surface area. The use of feet to spread the force of the bars over an increased surface area mitigates the potential for compression of the wall covering captured therebeneath.
