HEADSET I Filed Feb. 10, 1949 2 SHEETSSHEET 2 INVENTOR. RUSSELL; C. GILBERT WM Wm ATTORNEYS Patented Feb. 19, 1952 HEADSET Russell 0. Gilbert, Stillwater, Minn., assignor to Telex Inc., Minneapolis, Minn., a corporation of Minnesota Application February 10, 1949, Serial No. 75,709

This invention relates to head sets and more particularly to light-weight head sets of the type which are worn by telephone operators, dictaphone transcriptionists and others over long periods of time. Head sets have previously been provided wherein the sound reproducer units are mounted so as to provide direct communication from the sound reproducer unit to the ear. In such head sets the sound reproducer units have been mounted so as to fit over the ear of the user when the head set is used. In other head sets there have been provided a sound reproducer unit suspended below the chin of the wearer and provided with a harp or wishbone-shaped ear tubes leading to ear tips that are placed in the ears of the operator. All of the foregoing types of head sets are subject to the disadvantage that a certain amount of pressure is applied to the ear of the wearer, which is a sensitive portion of the body and is subject to the disadvantage that such pressure, however slight, when long continued may cause some discomfort of the wearer.

It is an object of the present invention to provide an over-the-head head set which can be worn by the operator for extended periods of time without pressure on the ears of the wearer.

It is more particularly an object of the invention to provide an over-the-head head set wherein the sound reproducing units are worn adjacent the ear and the sound communicated therefrom to ear tips which may be adjusted to any position in proximity with the ear, and either in or out of contact therewith.

It is a further object of the invention to provide an improved, light-weight, over-the-head head set having dual sound reproducer units and also to provide an over-the-head head set having sound reproducer units which, when worn by the operator, are located adjacent the ear and sound conduits provided therefrom equipped for adjustment so as to bring the conduit into close proximity or contact with the ear canal as desired.

Other and further objects of the invention include the provision of an improved light-weight head set having adjustable ear tips on the sound reproducer units and to provide an improved head set having a single or double cord arrangement to dual sound reproducer units of the head set.

Other and further objects of the invention are those inherent in the apparatus herein illustrated, described and claimed.

The invention is illustrated with reference to the drawings in which corresponding numerals refer to the same parts and in which:

Figure 1 is a front elevational view of one form of the invention;

9 Claims, (Cl. 179156) .t 22 of Figure 1;

Figure 3 is an enlarged sectional view taken along the line and in the direction of arrows 3-3 of Figure 1;

Figure 4 is a front elevational view of a slightly i modified form of the invention;

Figure 5 is an enlarged sectional view taken along the line and in the direction of arrows 5-5 of Figure 4;

Figure 6 is a quarter front view of an individual i Wearing the head set of Figure 4.

Referring to Figures 1, 2 and 3 there is illustrated a head set having duplicate sound reproducer casings generally designated 49 and H, each of which terminates in a side arm l2 and I3 into which a tubular head bow M of plastic material or the like is inserted. The construction of the sound reproducer casings It] or H is illustrated by the sectional view shown in Figure 2 wherein it will be noted that the casing is provided with a recess I5 into which the sound reproducer unit generally designated I6 is adapted to repose. The second reproducer unit 16 is of minute size of the type customarily used for hearing aid sets for the hard of hearing. The sound reproducer unit includes an exterior frame I1 terminating at a flange [8 in which the diaphragm I 9 of the sound reproducer unit is placed, the diaphragm being held in place by the magnetism of pole pieces 20. Coils surrounding the pole pieces, not illustrated, are connected to a pair of terminals, one of which is shown at 2| in Figure 2. The terminals are in the form of clips to receive parallel terminals 22 of a removable plug 23 which when inserted through holes 24 in the bottom portion of the casing permit connection to the terminals and hence to the sound reproducer unit. The casing I0 is provided with a screw plate 25 threaded or pressed into the casing Ill having an upstanding hub portion 25 that is threaded at 21 to receive the cap 28. The cap has a circular opening in its center and is provided with a spherical recess 29 which serves to hold the ball end 30 of short inflexible ear tube 3| which extends out of the hub II and terminates at an ear tip 36, see Figure l. The hub portion 26 has a spherical recess 32 corresponding to the shape of the ball 30 into which the ball portion 30 is placed before the cap 28 is tightened down. The ball 38 is bored so as to receive the ear tube 3| and the ear tube and ball portion provide a tubular conduit 33 through which the sound emanating from the diaphragm I9 is adapted to pass and be delivered to the ear tip 36.

The side arm portion l2 of the sound reproducer casing is bored out at 34 so as to receive the tubular head bow M which is preferably of plastic material, although light-weight metal may also be used. In the preferred embodiment of the invention the entire casing I is of molded plastic.

In the form of invention shown in Figure 1 a single cord 35 is provided having a pair of conductors which terminate at a plug 23 having a pair of terminal points of which one, viz. terminal 22, is shown in the sectional view, Figure 2, the other terminal point lying immediately behind the terminal 22. These pin terminals are engaged by a pair of spring terminals on the back of the sound reproducer unit 16, of which one such terminal 2| is shown, the other lying immediately behind, and as previously stated these terminals are connected to the coils of the sound reproducer unit,

Also connected to the terminals are a pair of wires in cord 31 which extends around the rear portion and up one side of the sound reproducer unit and thence through the aperture 38 and into the inside of the tubular head bow l4, whence it extends around to the opposite sound reproducer casing H, which, as previously stated, is identical with that shown at H] and in Figure 2 just described. In that sound reproducer casing H the cord pair 31 is connected to corresponding terminals on the back of the sound reproducer contained within casing ll. It will be noted that the casing II has a pair of apertures at 39 to which the pin terminals of plug 23 may be inserted when it is desired to plug in the cord to the sound reproducer casing ll instead of to the sound reproducer casing ID, as shown. In this way the operator has freedom of choice in that she may plug the cord 35 into either of the sound reproducer casings, depending upon which side she desired to have the cord hung when the set is worn. Within the tubular head bow l4 there is also placed a springy stiffening wire 40 which provides slight pressure and still, when bent, can be adjusted as to to fit the heads of individual operators.

When the sound reproducer shown in Figures 1-3 is worn on the operator, the sound reproducer casings IB and II are positioned at approximately the temples of the wearer and the ear tubes 3| and 4| extending from the sound reproducer casings l0 and H, respectively, and terminating in ear tips 36 and 42, are then adjusted by the operator so that the ear tips reach into proximity to the ear canal. It is unnecessary, for satisfactory operation, to have the ear tube actually in contact with the wearer, although some may desire to adjust the ear tubes to such position. Consequently, the wearer may, if desired, adjust the ear tubes so as to receive the sounds delivered by the ear tips 3542 without enduring any pressure whatever on the ear canel or any portion of the ear, the slight tension of the bow I4 which provides the pressure of sound reproducer casings Ill-ll on the wearer being taken instead by the sturdier portions of the head of the wearer, viz. the temples portion. Also, if desired, the wearer may shift the head set from one position to another so as to shift the pressure of the sound reproducer casings ill-4| from one spot to another on the temple or over-ear or behind-ear portions of the head and in any position the short adjustable ear tubes 3I-4l can be repositioned so as to bring the ear tips 36-42 into proximity with the ear canal. This is a distinct advantage when the device is worn for long periods of time.

Referring to the device shown in Figure 4. it is exactly the same as that shown in Figures 1-3 with the exception that the interconnecting pair of wires 3'! between the sound reproducer head set is omitted in the over-the-head bow [4. Accordingly, the sound reproducer units within the casing in and H are not interconnected electrically and for the purpose of communicating the electrical sound-signals to the sound reproducer unit there is provided a branched cord shown generally at 45 terminating in a connection block 46 from which a pair of cords 41-48, which are connected parallel to the wires of cord 45, emanate. The cords 4'|48 are each provided with plugs connectors at 49-50, respectively, which are plugged or jacked into the openings provided in the base of the sound reproducer casings |0H, thus making electrical connections to the sound reproducers therein. As shown in the sectional view in Figure 5 the over-the-head bow I4 includes a stiffening wire 40 as previously described, but there is no electrical connection in the tube [4. Figure 6 is self-explanatory and illustrates one position in which the head set shown in Figure 4 may be worn by the operator. It is to be understood that the twin cord generally designated 45-46-41-4B shown in Figure 6 may be substituted by the unit shown at 35 in the event the head bow M has electrical connection between the sound reproducers of the head set, as explained with reference to Figures 1-3.

As many apparently widely different embodiments of this invention may be made without departing from the spirit and scope thereof, it is to be understood that I do not limit myself to the specific embodiments herein.
