TITLE: Garment With Built-in Audio Source Wiring

This application is a continuation-in-part of application serial number 12/492,035 filed on June 25, 2009 the content of which is incorporated herein by reference and the priority of which is claimed.

FIELD OF THE INVENTION

The invention is in the fields of clothing and wiring for listening to portable audio sources such as MP3 players, CD players, cell phones, Bluetooth devices and the like. In particular for combinations of clothing and such wiring.

BACKGROUND

Wiring assemblies for portable audio sources for listening are ubiquitous. They are generically called headphones. One type of headphones adapted for portable use are called earbuds or earphones. They have at one end a connector to plug into a source device. This then leads to a pair of wires connected to the devices to be placed at the user's ears, usually held in or on the ear.

A user carries the wiring assembly with her and connects it up to the source device and sets the headphones at the ears. The wiring has to be carried and kept available for use, and it is commonly a nuisance to find it and then to use it. In use it is kept usually outside the clothing, the headphones being at the ears and the audio device held in the hand or placed in a pocket.

The wiring may not be waterproof, but recently waterproof wiring has been developed and is available. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

In the present invention wiring for an audio device, including headphones and earphones are permanently installed into a garment.

An exemplary earphone wiring assembly 10 as in Fig. 1 is of the type including a connector 12 for connecting to an audio source device, typically with paired analog audio transmission wires 14a and 14b joined together along a joined wire portion 16 for some distance to a separation point 18 typically having a strain relief member 20 from which the transmission wires 14a' and 14b' extend separately terminating at the earphones 22a and 22b. While the term earphone wiring will be used in this description it is intended to mean any of the type with a connection to a source device and a pair of listening instruments, one for each ear. Typically an analog signal travels from the source device to the earphones.

In exemplary form the garment is a hooded garment 30 as shown in Fig. 2. In other exemplary forms the garment is a conventionally collared shirt, and in still others it has a plain hemmed neck such as a crew neck. In the case of the hooded garment, it may be in jacket form, that is open down the front (with a zipper or other closure means) or in pull-over form like a sweater. However in each case for purposes of embodiments of this invention there is a channel or casing as will be described. In this description the terms left and right refer to the wearer's left and right. As shown in Fig. 2, the earphone wiring 10 is installed into the garment so that the connector 12 is accessible near a pocket 32 and the right and left earphone wires 14a' and 14b' exit the garment inside hollow lanyards (also called drawstrings) 36a and 36b on each side of the hood 34 near the user's ears terminating at the right and left earphones 22a and 22b. As will be described in more detail below, the portions of the earphone wiring 10 from the connector 12 to which access is not needed and which runs up to the hood 34 is captured in the garment. Also shown in Fig. 2 are right and left tubular lanyards 36a and 36b. These are used to cover the earphone wires 14a' and 14b' and also as the hood lanyards, for adjusting (called cinching) the hood 34. The hollow lanyards are knitted or may be hollow flexible plastic

Fig. 3 shows an example of how the wire portion 16 extends into the pocket 32 and exits the inner wall of the pocket 32 through an opening 40 so that it is in the inside of the garment 30, as further described below with reference to Fig. 4

Fig. 4 shows an example of how the earphone wiring 16 is brought from a location inside the pocket 32 into the hood channel 38. This is done by passing the joined wire portion 16 through an opening 40 inside the pocket, which opening can be a button hole or a grommet to the inside of the garment. Then it enters a first, lower end of and travels through a channel or casing 42 which is sewn into the inside of the garment, in this case along the stitch line 46 that also attaches a zipper 44. Then it exits the channel 42 at a second, upper end, and enters the hood channel 38 (also called a casing) which is defined by the stitching 48, through an opening 50 defined by a button hole or other hole device such as a grommet, entering on the side of the hood channel 38 which is on the interior of the hood 34 and extends to the separation point 18 at which the wires separate. Further detail inside the hood channel 38 is described below.

Installation of the wiring can be done with a garment that does not have a pocket, in which case the wiring can simple extend beyond the bottom of the garment, or it can pass through an opening in the garment.

Fig. 5 shows a view of the inside of the hood channel 38 with a portion cut-away to show the interior of the channel. The joined portion 16 comprising the wires 14a and 14b enters the hood channel 38 as described above with reference to Fig. 4, and this portion is placed so that the strain relief member 20 at which they separate is approximately at the center of the hood 34. The right and left separate wires 14a' and 14b' are installed inside the right and left hollow lanyards 36a and 36b respectively. The assembly at the point where the wires 14a' and 14b' exit the strain relief 20 into the hollow lanyards 36a and 36b is described in Figs 6 - 8 below. The right and left hollow lanyards 36a and 36b with the right and left wires 14a' and 14b' respectively, inside them exit the hood channel 38 through openings 52a and 52b, which in this embodiment are on the outside of the hood channel 38, although they could be on the inside.

Fig 6 shows an embodiment for a secure "Y" connection of the wires inside the hood channel 38. In this embodiment the strain relief also called a securing piece 20 is a plastic barrel that has been molded over the separation point 18 where the joined wires 14a and 14b separate into the separate wires 14a' and 14b'. It is also at this point that the wires 14a' and 14b' enter the hollow lanyards 36a and 36b respectively. The securing device 20 tightly holds the ends of the lanyards with respect to each other and the wires. This will be referred to as the securing point 54.

It is preferable that the lanyards 36a and 36b with the wires inside them be attached to the garment inside the hood channel 38 to avoid pulling them laterally in one direction or the other such as by uneven pulling. There are various ways that this can done. One way is to secure the assembly to the garment at or near the securing point 54. In one embodiment this is done as shown in Figs. 5, 7 and 8 with a fabric strip 56 secured around the securing piece 20, stitching and gluing being exemplary. It is then co-sewn into the hem stitch 46 which defines the casing or channel 38. The detail is shown in Fig. 8 in which the fabric strip 56 is sewn at 58 to help secure it around the securing piece 20. Then, after it has been set in place, it is co-sewn with the hood channel hem as shown at Fig. 10 shows another embodiment for fixing the lanyard/wire members against lateral movement. In this embodiment, the securing piece 20 is captured between stitch lines 66 on either side. Of course the stitch lines 66 have to avoid the wiring.

As explained above, an embodiment of the invention combines the hood lanyards 36a and 36b with the separate wire portions 14a' and 14b' so that the hollow lanyards serve two purposes, one is to tighten the hood, and secondly as conduits for the separate wire portions 14a' and 14b'. The ends of the lanyards 36a and 36b are secured to the earphones 22a and 22b, which in the figures are shown as the earbuds type of earphones.

To manufacture the assembly so that the wiring is permanently installed in the garment, the separate wires 14a' and 14b' are first strung through the lanyards 36a and 36b. Then the molded barrel 20 is molded into place at the "Y" junction securing point 54 joining the wires and the lanyards at one end. Then the other ends of the combined lanyards and wires are crimped to a strain relief connection fitting 62 as shown in Fig. 9a, and then the stripped wire portion 64 is attached to the earbuds 22a and 22b and the connection fitting 62 is secured to the earbuds 22a and 22b as shown in Fig. 9b.

While in this description, the terms right and left have been used to understand the location of the lanyards, the wires and the earphones with respect to the garment; it should be understood that the location may but does not necessarily consistently apply to the attachment to a user's left and right ear. A user may attach the left earphone to the left ear and the right earphone to the right ear. But a user can elect to do the opposite; and when the lanyards are tied in a conventional bow, the left and right earphones will reverse their relative location.

A further embodiment is shown in Figs. 11, 12, and 13 which are progressive assembly and the enlarged views of Fig. 14. In Fig. 11 there are shown an earbud 102 ready for assembly to a lanyard assembly 104. The earbud is made up of a housing 106 a sleeve 108, (also seen as 62 in the description above) and a speaker or electronics assembly 110 and also a crimp element 112. The lanyard assembly 104 includes a lanyard 114 (described above as 36a and 36b), typically of woven construction and internal wiring 116 (described above as wires 14a and 14b on one side and 14a' and 14b' on the other side). Projecting beyond a terminal end 118 of the lanyard, the internal wiring 116, which consists of a two wire cable, has been stripped to provide bare wire 120 with terminal ends for connection to the speaker assembly 110. A glue drop is schematically illustrated at 122.

The housing 106 has a generally open interior and an opening 124 at its rear end to snugly, or interferingly receive the sleeve 108 and an opening 128 to receive the speaker assembly 110. The sleeve 108 has an passageway 130 through it from a front end 132 to a rear end 134. The passageway 130 may be tapered as shown from front to rear. Although it is shown as straight, the sleeve may have another shape with the passageway extending through it accordingly

In Fig. 12 those same elements are shown partially assembled. To perform the assembly, the lanyard assembly 104 has been threaded through the sleeve 108 to extend beyond the front end 132. Then, the crimp element 112 in the form of coiled wire has been applied proximate the terminal end 118 of the lanyard assembly 104, and crimped. This can be seen in Fig. 14. The crimp element 112 secures the lanyard 104 and the wire 116 together so that they are fixed together at that point, that is there can be no relative movement between them and no movement of or force on the lanyard 114 is transmitted to the portions of the wires 120 that will be attached in the earbud speaker assembly 110. The crimping is also shown in enlarged form in Fig. 14 showing application of the crimp element 112 in the form of a coil of wire before and after crimping. More than one crimp element can be applied to ensure a secure crimp. Other elements can be used as the crimping element which can be closed or crushed down and will secure the lanyard 114 and the wire 120 against relative movement, for example a small lock- washer can be crimped in place. Then, the lanyard assembly 104 is pulled back (see the arrow A in Fig. 14) to pull the crimp element 112 into the passageway 130 where it is firmly captured by the wall of the passageway 130 with the bare wires 120 available for connection, as shown in Fig. 12. This is also shown in Fig. 9a. The wires 120 are attached to terminals of the speaker assembly 110 and glue 122 is applied into the passageway 130 The sleeve 108 is assembled to the housing 106 and the speaker 110 is assembled to the housing 106 where the parts are all fixed together by sonic welding. This final assembly is shown in Fig. 13 and also in Fig 9b.

The wire 120 inside the lanyard 114 is slack as shown by the undulating portion whereby the combination of the slack and the crimping at the end allows any stretching of the lanyard 114 to be applied to the slack of the wire thereby freeing the wire from forces such a pulling on it put on the lanyard 114 and also prevents strain from communicating past the crimp point to the wires inside the housing. That means that as the user pulls on the lanyard such as to tie it or pull the hood tight, due to the slack, the wire 116 will not be subject any stretching or other forces caused by use of the lanyard.. In other words, the wire 116 inside the lanyard 114 is independent of the lanyard 114 by reason of the slack and at the same time, the wires 120 beyond the crimp are also free of strain that might be caused bu use of the lanyard.

Another embodiment is shown in Fig. 15 in which the lanyard assembly is further developed for a Bluetooth receiver/transmitter 150. In this embodiment, the connector 12 is connectable to a Bluetooth receiver/transmitter 150. One of the wires 14a' or 14b' has a microphone 152 connected to it which has an internal pressure switch. The Bluetooth receiver/transmitter 150 is equipped with an on-off switch 154 and other electronic elements common to such devices. The user simply connects the Bluetooth device 150 and can listen to any incoming recorded message or to a live person and can respond by turning on and using the microphone 152. When the lanyard assembly is used for just listening such as to music via an MP3 player or the like the same wiring performs as described above.
