HEADSET AND USE HEREOF
STATE OF THE ART
The invention relates to a telephone headset as set forth in the preamble of claim 1.
Quite a number of different types of telephone headsets are known, which are arranged to be carried on a person's outer ear only, in that the headset comprises a sound reproducer with a telephone or a loudspeaker, a support member which is often designed so as to be at least partly adapted to the shape of the outer ear and in such a manner that the sound reproducer is positioned opposite the sound entrance of the ear, and a microphone arm or bar with a microphone.
.
Such a telephone headset is known for instance from appli-cant's Danish patent no. 157,289 and the corresponding US
patent no. 4,893,344. This telephone headset further com-prises means, viz. an adjustable stabilizer for individual ; ad~ustment, and comprises an ad~ustable microphone arm for individual positioning of the microphone. Thus, the tele-phone headset comprises a number of parts which are rotat-able or displaceable in relation to each other, whereby individual adjustment is achieved and so that the telephone headset may be carried on the right or the left ear as desired. The large number of parts and their movability increase the costs of production and assembly of a tele-phone headset, and further, it has turned out that some headset users find it difficult to quickly adapt the many possibilities of adjustment when moving the telephone head-set, e.g. from the left to the right ear.

DESCRIPTION OF THE EMBODIMENTS
, Fig. l shows a telephone headset 1 comprising a mlcrophone or a sound receiver 2, an elongated support member or ob-ject 7, a sound reproducer 3, and a wire 9 containing both the microphone and the sound reproducer wires, usually a four conduct wire. The microphone 2 and the sound repro-, .

ducer 3 are arranged at each their end of the elongated support member 7, whiah is arranged 80 that the microphone wlre can be placed herein.
In the embodiment shown in fig. 1 the telephone headset 1 is applicable as an ordinary handset, as known from ordin-ary telephone apparatus.
The support member 7 is of a material or a combination of materials or a construction allowing it to be configured in a substantially inelastical manner by bending. However, any configuration is reversible on desire. The support member or ob~ect 7 is simply designed so as to be configurable by bending at any spot and in any direction and to the effect that after being bent the member remains stabile, i.e. the bend is inelast~c.
In figs. 2 and 3 is shown how the telephone headset 1 is applicable around a person's outer ear, constituting a ; 20 telephone headset, viz. in such a manner that the sound re-producer is placed at the sound entrance of the outer ear and in such a manner that the microphone 2 is placed e . g.
- opposite the user's mouth. The configuration applied to thetelephone headset by ordinary bending has been executed by the user himself. The support member or ob~ect 7 is made of a material which the user can simply configure as desired by bending it with his fingers.
. In fig. 2 the telephone headset is shown with the micro-phone arm appearing below the ear 20 and with the wire 9 likewise led behind the ear, whereas fig. 3 shows how the microphone arm appears above the ear 20, whereas the wire 9 simply hangs from the ear. Thus, a part 11 of the member 7 extends hidden behind the outer ear 20. The wire 9 is con-nected to the sound reproducer 3 immediately next to the con~unction of the support member 7. This is only for ~' 13B13, 03~06-1992 , ' , : : :' :'::, :. . ~ . : .: ::: ' :' :: '::

7 ~70~6 exempllfication, and there i9 no hlndrance why the wlre 9 should not be connected to the telephone headset anywhere else.
In the sectional figure in fig. 3 is shown an embodlment of the support member 7 ln the form of a so-called metal hose, e.g. a convolute tube consisting of a convolute steel band or a convolute steel wire 13 and a convolute copper wire 14 wound at a slightly larger diameter than the steel member.
The flexible tube is surrounded by a polyurethane tube 12 which is e.g. shrunk around the metal hose. Hereby a metal hose is achieved which is flexible in any direction and remains in the bent position. In the centre of the metal hose the microphone wire 15 is inserted.
Figs. 4, 5a and 5b show sections of the telephone headset in fig. 1, figs. 5a and 5b showing different examples of the cross-sectional profile. In this embodiment the support member 7 consists of a rubber or plastic tube 10 surround-ing a central core 8 of a soft metal, e.g. annealed copperor iron wire. Further, the microphone wires 4 have been em-bedded or inserted. Usually, the plastic or rubber material 10 will be elastically deformable, and the core 8 will be inelastically deformable. If the central core 8 is of an electrically conducting material, it may of course be applied as e.g. microphone wire, in that the central core may be separated longitudinally in two from each other electrically insulated conductors. The plastic or rubber material lO may e.g. be Neopren cell rubber, foam PVC and similar materials which are fusible or configurable as desired.
Figs. 6a and 6b show further embodiments of the telephone headset according to the invention. In fig. 6a is shown an open supra aural sound reproducer 3 with mounted foam rub-ber 16. A cast of hard or soft plastic could also be mount-13EJ13, 03/06-1992 --: : ' ` ` :

In fig. 6b is shown another embodiment of a sound repro-ducer on which is mounted a standard "cast" 17 of foam rub-ber, soft rubber, plastic or the like, whereby increased comfort and better acoustic connection between the sound reproducer and the ear is achieved, but without the ad~ust-ment being individual for one user or one ear.
In fig. 7 is shown an embodiment in which the support mem-ber is separated into two areas 7a and 7b, the sound repro-ducer 3 being fixed to the support member or around the support member at some distance from its one end by means of a holder or fitting 21. At the end opposite the micro-phone 2 a stabilizer 22 is arranged which e.g. may be ball-shaped as shown, but may be shaped differently. The stabil-izer which may be made of soft plastic or of the same ma-terial as the rest of the support member is intended for supporting behind the ear, e.g. in the same way as the sta-bilizer of applicant's US patent No. 4,893,344, or in the same way in which the thickening of a side bar supports behind the ear. During use, the telephone headset is placed with the holder or fitting 21 in front of the ear, and so that the sound reproducer 3 is placed correctly opposite the ear, whereupon part 7b with the stabilizer 22 is bent and placed behind the ear, and part 7a of the support mem-ber constitute~ a microphone bar which may be bent for suitable positioning of the microphone 2. The stabilizer 22 may also be arranged to render a c0rtain balancing of weight of the telephone headset. The wire 9 is in fig. 7 shown extending directly from the sound reproducer 3.

2 ~7 ~,'!3 The embodiment in flg. 8 comprises a through-golng support member in the same way as the embodiment in fig. 1, but the wire 9 extends via an opening in the stabilizer 22. A wire pair 23 for a sound reproducer 24 of the type open intra-concha extends through the same opening. The sound repro-ducer 24 comprises a foam rubber cap 25. Such a sound re-producer construction is also called an "earbud".
Figs. 9a and 9b show other embodimants of the invention using an "earbud" as a sound reproducer, in which, however, the sound reproducer is connected to the telephone headset via a housing 26 or a similar connection member arranged at a distance from the one end of the support member. The housing 26 may also be configured in plastic and surround the support member as shown, but may also be configured differently. The wire 9 may extend from the housing 26 (fig. 9a) or via the stabilizer 22 (fig. 9b). The housing 26 may contain inactive or active electronic circuit com-ponents, e.g. for adapting the microphone or the sound re-producer of the telephone headset to the equlpment or clr-cuit to which the telephone headset is to be connected.
Figs. lOa and lOb show further embodiments of the telephone headset according to the invention. In these embodiments 2~ the housing 29 contain the sound reproducer itself or a miniature loudspeaker from which the sound via a sound hose 27 is transmitted to the sound reproducer 28, a so-called "eartip", e.g. in the same way as in a behind-the-ear hear-lng aid. The sound reproducer 28 may be a standard eartip, e.g. of foam rubber or similar material, but may also com-prise an individual cast of the user's ear cavity. The wire 9 may extend from the housing 29 (fig. lOa), either in front of or behind the ear during use, or the wire 9 may extend through the stabilizer 22 (fig. lOb). In the housing 2g there may in addition to the sound reproducer or a mini-ature loudspeaker be arranged inactive or active electronic 13313, 03/t~6-1992 - . . ~ ' i , ' : :. .:

circuit members, e.g~ amplifiers or impedance adJusting circuits.
From the above description it will be obvious to a man skilled in the art that for a sound reproducer any known type is applicable, e.g. supra aural, supra concha or intra concha, of open or closed type, or an eartip with a sound tube of any known type, without deviating from the original idea of the invention.
The microphone or microphone housing 2 is shown schematic-ally only. It will be obvious to a man skilled in the art that any microphone is applicable in the microphone hous-ing, e.g. a dynamic microphone, an electret microphone, a ceramic microphone or a magnetic microphone, without there being any need for principally altering the telephone head-set according to the invention.
It will be obvious to a man skilled in the art that the support member 7a, 7b of the telephone headset may be ex-ecuted or configured with any cross-sectional profile and any desired variation of cross-sectional area, e.g. gradu-ally increasing cross-sectional area towards the sound re-producer, without deviating from the invention. Further, it is obvious to a man skilled in the art that the support member may be configured or made of any suitable material or any suitable composition of materials or construction in order to achieve the desired characteristics, without devi-at1ng from the basic prlnc1p1ec of the lnventl~n.

In the sectional figure in fig. 3 is shown an embodlment of the support member 7 ln the form of a so-called metal hose, e.g. a convolute tube consisting of a convolute steel band or a convolute steel wire 13 and a convolute copper wire 14 wound at a slightly larger diameter than the steel member.
The flexible tube is surrounded by a polyurethane tube 12 which is e.g. shrunk around the metal hose. Hereby a metal hose is achieved which is flexible in any direction and remains in the bent position. In the centre of the metal hose the microphone wire 15 is inserted.
Figs. 4, 5a and 5b show sections of the telephone headset in fig. 1, figs. 5a and 5b showing different examples of the cross-sectional profile. In this embodiment the support member 7 consists of a rubber or plastic tube 10 surround-ing a central core 8 of a soft metal, e.g. annealed copperor iron wire. Further, the microphone wires 4 have been em-bedded or inserted. Usually, the plastic or rubber material 10 will be elastically deformable, and the core 8 will be inelastically deformable. If the central core 8 is of an electrically conducting material, it may of course be applied as e.g. microphone wire, in that the central core may be separated longitudinally in two from each other electrically insulated conductors. The plastic or rubber material lO may e.g. be Neopren cell rubber, foam PVC and similar materials which are fusible or configurable as desired.
Figs. 6a and 6b show further embodiments of the telephone headset according to the invention. In fig. 6a is shown an open supra aural sound reproducer 3 with mounted foam rub-ber 16. A cast of hard or soft plastic could also be mount-13EJ13, 03/06-1992 --: : ' ` ` :

8 207~fi ed on the sound reproducer, whlch renders fine acoustlc connection to the ear, a so-called closed supra aural sound reproducer; however, this means that the telephone headset is applicable only by the person in question and only on the ear of which the cast has been taken.
In fig. 6b is shown another embodiment of a sound repro-ducer on which is mounted a standard "cast" 17 of foam rub-ber, soft rubber, plastic or the like, whereby increased comfort and better acoustic connection between the sound reproducer and the ear is achieved, but without the ad~ust-ment being individual for one user or one ear.
In fig. 7 is shown an embodiment in which the support mem-ber is separated into two areas 7a and 7b, the sound repro-ducer 3 being fixed to the support member or around the support member at some distance from its one end by means of a holder or fitting 21. At the end opposite the micro-phone 2 a stabilizer 22 is arranged which e.g. may be ball-shaped as shown, but may be shaped differently. The stabil-izer which may be made of soft plastic or of the same ma-terial as the rest of the support member is intended for supporting behind the ear, e.g. in the same way as the sta-bilizer of applicant's US patent No. 4,893,344, or in the same way in which the thickening of a side bar supports behind the ear. During use, the telephone headset is placed with the holder or fitting 21 in front of the ear, and so that the sound reproducer 3 is placed correctly opposite the ear, whereupon part 7b with the stabilizer 22 is bent and placed behind the ear, and part 7a of the support mem-ber constitute~ a microphone bar which may be bent for suitable positioning of the microphone 2. The stabilizer 22 may also be arranged to render a c0rtain balancing of weight of the telephone headset. The wire 9 is in fig. 7 shown extending directly from the sound reproducer 3.

2 ~7 ~,'!3 The embodiment in flg. 8 comprises a through-golng support member in the same way as the embodiment in fig. 1, but the wire 9 extends via an opening in the stabilizer 22. A wire pair 23 for a sound reproducer 24 of the type open intra-concha extends through the same opening. The sound repro-ducer 24 comprises a foam rubber cap 25. Such a sound re-producer construction is also called an "earbud".
Figs. 9a and 9b show other embodimants of the invention using an "earbud" as a sound reproducer, in which, however, the sound reproducer is connected to the telephone headset via a housing 26 or a similar connection member arranged at a distance from the one end of the support member. The housing 26 may also be configured in plastic and surround the support member as shown, but may also be configured differently. The wire 9 may extend from the housing 26 (fig. 9a) or via the stabilizer 22 (fig. 9b). The housing 26 may contain inactive or active electronic circuit com-ponents, e.g. for adapting the microphone or the sound re-producer of the telephone headset to the equlpment or clr-cuit to which the telephone headset is to be connected.
Figs. lOa and lOb show further embodiments of the telephone headset according to the invention. In these embodiments 2~ the housing 29 contain the sound reproducer itself or a miniature loudspeaker from which the sound via a sound hose 27 is transmitted to the sound reproducer 28, a so-called "eartip", e.g. in the same way as in a behind-the-ear hear-lng aid. The sound reproducer 28 may be a standard eartip, e.g. of foam rubber or similar material, but may also com-prise an individual cast of the user's ear cavity. The wire 9 may extend from the housing 29 (fig. lOa), either in front of or behind the ear during use, or the wire 9 may extend through the stabilizer 22 (fig. lOb). In the housing 2g there may in addition to the sound reproducer or a mini-ature loudspeaker be arranged inactive or active electronic 13313, 03/t~6-1992 - . . ~ ' i , ' : :. .:

circuit members, e.g~ amplifiers or impedance adJusting circuits.
From the above description it will be obvious to a man skilled in the art that for a sound reproducer any known type is applicable, e.g. supra aural, supra concha or intra concha, of open or closed type, or an eartip with a sound tube of any known type, without deviating from the original idea of the invention.
The microphone or microphone housing 2 is shown schematic-ally only. It will be obvious to a man skilled in the art that any microphone is applicable in the microphone hous-ing, e.g. a dynamic microphone, an electret microphone, a ceramic microphone or a magnetic microphone, without there being any need for principally altering the telephone head-set according to the invention.
It will be obvious to a man skilled in the art that the support member 7a, 7b of the telephone headset may be ex-ecuted or configured with any cross-sectional profile and any desired variation of cross-sectional area, e.g. gradu-ally increasing cross-sectional area towards the sound re-producer, without deviating from the invention. Further, it is obvious to a man skilled in the art that the support member may be configured or made of any suitable material or any suitable composition of materials or construction in order to achieve the desired characteristics, without devi-at1ng from the basic prlnc1p1ec of the lnventl~n.
