BACKGROUND
This invention relates to a headset.
As the number and type of mobile communication and entertainment devices grows so does the variety of headsets used with such devices. A flexible headset configuration would have the advantage of increasing user satisfaction. Further, a headset which allows a user to be exposed to ambient sounds would also be advantageous.
SUMMARY
In one aspect, a headset comprises a first connector, a second connector, a first earphone, and a second earphone. A first electrical pathway extends from a first contact point associated with the first connector to a first contact point associated with the second connector. A second electrical pathway extends from a second contact point associated with the first connector to a second contact point associated with the second connector. A third electrical pathway extends from a third contact point associated with the first connector to a third contact point associated with the second connector. At least one of the first earphone and the second earphone is connected between the first pathway and the third pathway and neither the first earphone nor the second earphone is connected between the first pathway and the second pathway.
In another aspect, a headset is provided with a headband, a first earphone mounted to the headband at a first fixed angle, and a second earphone mounted to the headband at a second fixed angle. The fixed first angle is equal and opposite to the fixed second angle such that the first earphone and the second earphone angle outwardly away from the headband. A first temple pad extends from the headband adjacent the first earphone and a second temple pad extends from said headband adjacent the second earphone. The first and second earphones extend rearwardly such that, in use, with the temple pads positioned at the temples of a wearer, the earphones project rearwardly and outwardly over, in spaced relation to, and approximately parallel to, ears of the wearer. In consequence of this, the wearer remains exposed to ambient sounds and remains able to distinguish the directionality of such sounds.
Other features and advantages will become apparent from the following detailed description in conjunction with the drawings.

DETAILED DESCRIPTION
Turning to FIGS. 1 to 3, an adjustable headset 10 has a U-shaped headband 12 with a first projecting tang 14a slidably received by a first earpiece sleeve 18a and a second projecting tang 14b slidably received by a second earpiece sleeve 18b. The headband terminates at a first end 20 in a first receptacle 22 (FIG. 3) and at a second end 24 in a second receptacle 26 (FIG. 3). An inwardly directed temple pad 28, 30 extends from the headband adjacent each of the first and second ends of the headband. Referencing FIG. 3, a first earphone 34 extends from the headband adjacent end 20 at a fixed first angle {acute over (α)} to a plane P extending transversely of the headset. A second earphone 38 extends from the headband adjacent end 24 at a second fixed angle β to plane P. Angles {acute over (α)} and β are equal and opposite acute angle β with respect to plane P, with angle β ranging from between about 30° and 60°. As such the earphones 34, 38 angle outwardly away from the headband 12. With this arrangement, as seen in FIG. 4, when the headset is worn by a wearer 40, the earphones 34, 38 are positioned over but spaced from, and more or less parallel to, the ears 42, 44 of the wearer. Because the earphones are spaced from a wearer's ears, the wearer will not only remain exposed to ambient sounds when wearing the headset but will also continue to be able to distinguish the directionality of ambient sounds. This increases safety for a wearer as well as enhancing the ability of the wearer to orally communicate with a nearby person.
As seen in FIGS. 1 and 2, a plug 50 may be connected to receptacle 22 (FIG. 3) and a plug 52 may be connected to receptacle 26 (FIG. 3). A cord 48 may extend from plug 50 which cord is connected to a device, such as a cell phone, a handheld radio, a personal entertainment device (as, for example, an MP-3 player), or other device which may be used with the headset. Plug 52 is assembled with a microphone 56 on a gooseneck boom 58. The gooseneck boom is flexible to allow adjustment of the position of the microphone.
Turning to FIG. 5, headset 10 may be wired as follows. A first electrical pathway 61 extends from a first, tip, contact point 71a associated with the first receptacle 22 to a first, tip, contact point 71b associated with the second receptacle 26. A second electrical pathway 62 extends from a second, medial, contact point 72a associated with the first receptacle 22 to a second, medial, contact point 72b associated with the second receptacle 26 and a third electrical pathway 63 extends from a third, sleeve, contact point 73a associated with the first receptacle 22 to a third, sleeve, contact point 73b associated with the second receptacle 26.
Notably, the first, tip, contact point 71a associated with the first receptacle 22 is located at a corresponding location to the tip contact point 71b associated with the second receptacle 26. Similarly, the second, medial, point 72a associated with the first receptacle 22 is located at a corresponding location to the second point 72b associated with the second receptacle 26, and the sleeve contact point 73a associated with the first receptacle 22 is located at a corresponding location to the sleeve contact point 73b associated with the second receptacle 26.
The speaker 66 which is part of the first earphone 34 (FIG. 1) is connected between the first pathway 61 and the third pathway 63. Similarly, the speaker 68 which is part of the second earphone 38 (FIG. 1) is connected between the first pathway 61 and the third pathway 63.
Plug 50 has three electrically conductive zones separated by non-conducting rings 76: a first, apical, zone 81, a second, medial, zone 82, and a third, basal, zone 83. A wire 91 of cord 48 (FIG. 1) is connected between the first zone 81 and a ground (common) connection of a device 86 with which the headset is used. A wire 92 of the cord is connected between the second zone 82 of the plug and a microphone input of the device 86. A wire 93 of the cord is connected between the third zone 83 of the plug and an audio source of the device 86. (If the device with which the headset is used lacked a microphone input, wire 92 would simply be unterminated.)
Plug 52 has three electrically conductive zones separated by non-conducting rings 106: a first zone 101, second zone 102, and third zone 103. The first zone 101 connects to the ground side of microphone 56 via wire 111 and the second zone 102 connects to the other side of the microphone through wire 112. The third conductive zone 103 is unterminated.
Notably, the first conductive zone 81 of plug 50 is located at the same position (namely the tip) of plug 50 as is the first conductive zone 101 of plug 52. Similarly, the second conductive zone 82 of plug 50 is located at the same position (namely the middle) of plug 50 as is the second conductive zone 102 of plug 52.
With this arrangement, when (as seen in FIG. 1) plug 50 is plugged into receptacle 22, the first zone 81 of the plug is electrically connected to first contact point 71a of the receptacle, the second zone 82 of the plug is electrically connected to the second contact point 72a of the receptacle, and the third zone 83 of the plug is electrically connected to third contact point 73a of the receptacle. In consequence, audio signals on wire 93 are connected to the third electrical pathway 63 of the headset and, therefore, to speakers 66 and 68. Additionally, any signals on the second electrical pathway 62 are directed on wire 92 to the microphone input of device 86. The third electrical pathway is common to both the microphone input and the speakers and completes both electrical circuits.
With (as seen in FIG. 1) plug 52 plugged into receptacle 26, first zone 101 of the plug is electrically connected to first contact point 71b of the receptacle, second zone 102 of the plug is electrically connected to the second contact point 72b of the receptacle, and third zone 103 of the plug is electrically connected to third contact point 73b of the receptacle. In consequence, audio signals from the microphone 56 are connected to the second electrical pathway 62 of the headset and, therefore, to wire 92 of plug 50, assuming that plug 50 is plugged into receptacle 22.
Notably, rather than plugging plug 50 into receptacle 22, this plug could be plugged into receptacle 26 and the first 91, second 92, and third 93 wires from the plug would still be connected to the first 61, second 62, and third 63 electrical pathways of the headset. Similarly, plug 52 could be plugged into receptacle 22 and the first 111 and second 112 wires associated with the plug would still be connected to the first 61 and second 62 electrical pathways of the headset. FIG. 6 illustrates headset 10 with plug 50 plugged into receptacle 26 and plug 52 plugged into receptacle 22. In FIG. 6, the boom 58 of microphone 56 has been bent around so that the microphone will lie in front of the mouth of a user. Thus, headset 10 can accommodate a user preference for the microphone to extend from the left side of his face or from the right side of his face. The headset can also accommodate a user preference for the cord 48 to extend down from the left side of his head or the right side of his head.
FIG. 7 illustrates an alternate wiring for the headset wherein like parts to the wiring of FIG. 5 have been given like reference numerals. Turning to FIG. 7, in addition to first 71a, 71b; second 72a, 72b; and third 73a, 73b contact points on receptacles 122 and 126, respectively, each receptacle has a fourth contact point 74a, 74b which connects to a fourth electrical pathway 64 of the headset. With this arrangement, speaker 66 connects across the first and fourth pathways 61, 64 and speaker 68 connects across the first and third pathways 61, 63.
The headset wiring of FIG. 7 may be used with the plug 50 and device 86 of FIG. 5. In such instance, the third zone 83 of the plug 50 will be electrically connected to both the third and fourth points 73a, 74a of receptacle 122. Consequently, both pathways 63 and 64 will be connected to this third zone of the plug and so, therefore, speakers 66 and 68 will be simultaneously connected to this third zone. Alternatively, plug 50 may be replaced by plug 150 which has a fourth zone 84 such that one audio signal is supplied by a device 186 to the third zone 83 and a second audio signal is supplied by the device 186 to the fourth zone 84. The audio signal supplied to the third zone will be applied to speaker 68 and the audio signal supplied to the fourth zone will be applied to speaker 66. In this way, device 186 may supply a stereo signal to the speakers.
The headset wiring of FIG. 7 could not be used with the plug 52 of FIG. 5 since the unterminated third zone 103 would short the third 63 and fourth 64 pathways. Therefore, a plug 152 is used instead. Plug 152 has a first zone 101 connected via wiring 111 to one side of microphone 56, a second zone 102 connected via wiring 112 to the other side of the microphone and unterminated electrically isolated zones 103 and 104.
As with the wiring of FIG. 5, plugs 150 (or 50) and 152 can each be inserted in either one of receptacles 122 and 126.
FIG. 8 illustrates a further wiring for the headset wherein like parts to the wiring of FIG. 7 have been given like reference numerals. Turning to FIG. 8, in addition to first 71a, 71b; second 72a, 72b; third 73a, 73b; and fourth 74a, 74b contact points on receptacles 222 and 226, respectively, each receptacle has a fifth contact point 75a, 75b which connects to a fifth electrical pathway 65 of the headset. With this arrangement, speaker 66 connects across the first and fourth pathways 61, 64 and speaker 68 connects across the first and fifth pathways 61, 65.
The headset wiring of FIG. 8 may be used with plug 250 which has a fifth zone 85 such that one audio signal is supplied by a device 286 to the fourth zone 84 and a second audio signal is supplied by the device 286 to the fifth zone 85. The audio signal supplied to the fourth zone will be applied to speaker 66 and the audio signal supplied to the fifth zone will be applied to speaker 68. In this way, device 286 may supply a stereo signal to the speakers. The third zone 83, which is connected to wire 93 of cord 248 may be connected to an alternate application of device 286 such as a voltage supply for light emitting diodes (LEDs) on the headset or, if unused, may simply be connected to ground.
The microphone 56 is associated with a plug 252 which has a first zone 101 connected via wiring 111 to one side of microphone 56, a second zone 102 connected via wiring 112 to the other side of the microphone and unterminated electrically isolated zones 103, 104, and 105.
As with the wiring of FIG. 5, plugs 250 and 252 can each be inserted in either one of receptacles 222 and 226.
In alternate embodiments, the male and female connectors could be reversed. Thus, the described plugs could project from the headset 10 and the described receptacles could terminate the attachments (e.g., cord 48 and microphone 56). In place of the described receptacle and plug connectors other connector pairs could be substituted, such as miniature circular connectors or mixed gender connectors.
Other attachments than those shown could be provided. For example, a plug could be coupled with a short range transceiver (e.g., a BLUETOOTH™ transceiver) in place of connection cord 48.
Other modifications will be apparent to those skilled in the art and, therefore, the invention is defined in the claims.
