FIG. '2-

United States Patent 3,375,333 DUAL MICROPHQNE Leon H. Hagopian, 29 N. Highland Ave., Lansdowne, Pa. 19050 Filed Oct. 5, 1964, Ser. No. 401,417 2 Claims. (Cl. 179-148) ABSTRACT OF THE DISCLQSURE A dual support for adjustably mounting two microphones, one for use by one person and the other for use by another person, the microphones being connected to one transmitter.

My invention relates to: Radio transmitting apparatus and particularly to the type of apparatus which is used by reporters for interviewing various persons on the street, or in meetings, and elsewhere,

It has been heretofore the practice for the reporter to carry a microphone which was connected to a walkietalkie transmitter strapped to this back or which was connectcd to a stationary transmitter some distance away. In either case, the reporter carried a wand which had a single microphone and when the reporter wanted to ask a question, he had to bring the microphone close to his mouth, and as soon as the question was finished the reporter had to place the microphone close to the month of the party to whom the question was addressed. This practice is annoying to the viewing television audience and represents a lot of work for the reporter. More important, experience has shown that the beginning and the end of any conversations by the reporter or by the party being interviewed, are lost because the reporter usually moves the microphone away from his mouth before he has quite finished the last word; the person replying usually begins to speak before the microphone has come close enough to his mouth, and because the reporter frequently pulls the microphone away before the party being interviewed has quite finished speaking, and so on.

Furthermore, in a jostlin crowd, be it a political convention or a riot, moving the single microphone back and forth could cause an accident.

It is, therefore, a further object of my invention to produce a microphone whereby the foregoing objections are completely overcome.

The full nature of the invention will be understood from the following specification and the accompanying drawing in which:

FIG. 1 is a highly diagrammatic elevational view of a radio transmitting apparatus embodying my invention.

FIG. 2 is a view similar to FIG. 1 but showing the apparatus as it is adjusted for use by two persons.

FIG. 3 is similar to FIG. 2 and shows a slightly modified embodiment of my invention.

The instrument shown in FIG. 1 includes a handle 10 which supports two independent, conventional transmitting mechanisms 12 and 14. Transmitting mechanism 12 includes a wand 16 which carries a conventional transmitting microphone 18 and is connected to handle 10 by a flexibie, and preferably, exp-ansible member 20. Similarly, transmitting mechanism 14 includes wand 22 which carries a transmitting microphone 24 and is also connected to handle 10 by a flexible, and preferably expansible member 26. Transmitting mechanism 12 is controlled by a switch 28 and transmitting mechanism 14 is controlled by switch 30. Transmitting mechanisms 12 and 14 are connected by wires 32 to a conventional transmitter not shown.

The apparatus illustrated in FIG. 3 differs from that shown in FIG. 1 only by providing members 16 and 22 with nested or telescoping extensions 34 and 36 whereby, in addition to adjusting the angle of a wand, it can also be lengthened or shortened; in use, the reporter wishing to interview a prospect, turns on switches 28 and 30, and adjusts one of the transmitters such as transmitter 14 to suit himself, and adjusts transmitter 12 to suit the person to be interviewed. By this arrangement, the reporter and the person being interviewed, can talk freely through constant reciprocation of a single wand and without danger of either of them being cut off. By manipulating switches 28 and 30, the reporter can control the material broadcast, both as to quality and quantity.

When the instrument is being used by the reporter only, transmitters 12 and 14 will be in the form shown in FIG. 1 and switch 28 will be turned off to de-energize microphone 18.

Since the broadcasting mechanism is old and forms no part of this invention, it is neither shown nor described.

What I claim is:

1. A portable support for a plurality of voice transmitters for use by a plurality of persons, said support including:

a handle,

at least two wands carried by, and individually movable relative to said handle,

each of said wands supporting a microphone, said miorophones being connected to a common lead.

2. The device defined in claim 1 wherein said wands are telescopically mounted for movement longitudinally of their axes and are flexible for movement to, and retention in, a selected position.
