Filed:

May 26, 1995

Appl. No.:

8/451492

Inventors:

Alan Weiss - Severna Park MD

International Classification:

H01R 3300

US Classification:

439502

Abstract:

An electric socket convertor comprises a convertor plug receivable into a conventional electric light bulb socket. An electric convertor socket is connectable with a conventional electric cigarette lighter. A connecting mechanism electrically connects the convertor plug to the convertor socket, such that electric current at the conventional electric light bulb socket is conducted through the convertor plug to the convertor socket. An electric cigarette lighter is inserted into the convertor socket, and is thereby provided with a source of 12-volt D. C. Other portable electric devices similarly can be provided with 12-volt D. C. The electric socket convertor provides convenient access to 12-volt D. C. for numerous electrical devices, and obviates permanent electric socket installation.

Alan Weiss - North Lauderdale FL
Thomas Brown - North Lauderdale FL

International Classification:

H04R 2500

US Classification:

381305

Abstract:

In accordance with the invention, there is provided a tapered slot coupler combined with a loudspeaker for providing a high degree of uniform angular sound distribution in the horizontal plane, and a sharp cut-off above the horizontal plane through the coupler-speaker combination. It also sends a greater amount of sound energy to the furthest point of the domain and diminishing energy in direction to the interior of the domain as one comes closer and closer to the sound source. A sound reproduction system cooperating with the coupler-speaker combination has a receiving domain for receiving the sound, a perimeter defining the domain, and a plurality of tapered slot high and medium frequency coupler-speakers disposed proximal to the perimeter facing the domain, and a plurality of low frequency loudspeakers also disposed along the perimeter facing the domain, wherein the high/medium frequency loudspeakers are of the tapered slot coupler-speaker combination type. The invention includes sound-energy generating apparatus operative for feeding sound energy to the speakers.
