Title: Wearable caddy for a personal audio device having integrated cord storage

Description:
BACKGROUND  
      1. Field of the Invention  
      The present invention relates to carrying and storage devices and more particularly to a wearable caddy for a Personal Audio Device having integrated cord storage.  
      2. Description of the Known Art  
      Wearable portable music players in various formats such as MP3 music players, radios and compact disc players are well known and very popular. I shall refer to these devices as personal audio devices or PADs. Examples include the Apple iPod® and the Sony® Walkman®. PADs are usually attached to the arm or belt of the user and generally require the use of a listening device such as conventional headphones or miniature in-ear speakers (referred to hereafter as “earphones”) to listen to the player privately and in comfort. A thin wire attaches the player to the listening device. These fixed-length wires are typically provided with the PAD upon purchase. The wires are a standard length and adapted for listening device use by tall as well as short individuals. Therefore for shorter or average sized persons, there may be excess wire dangling from the PAD. For an active individual, either walking or running, the excess wire can interfere with body movement resulting in the dislodgement of the listening device. Due to the length of the wire the listening device can drop from the head to the ground. This is at least a recurring nuisance and can damage the device. In other conditions the wire can be a snagging hazard and increase the risk of tripping the user or entangling in a moving object such as a rotating bicycle wheel. Users will often attempt to modify the length of the wire to a desired length by storing the excess wire in a pocket or by using a rubber band or wire tie to wrap the excess wire into loops. These temporary solutions are not effective because they can unravel and thereby create impediments to the easy and comfortable enjoyment of the PAD.  
      More formal attempts have been made to overcome some of these disadvantages. One example is U.S. patent application Ser. No. 11/027,405 by Mr. Bill Tsand Chun Chee published on Jul. 7, 2005 and entitled “Headset Cord Retainer”. The Chee device comprises a spool about which the excess wire is wrapped. The audio plug and the earphones extend from the spool through slots. In operation, the device is positioned between the earphones and the PAD. When not in use the device acts as a separate storage device for the PAD earphone-cord and earphone. One disadvantage associated with this device is the fact that the cord is stored apart from the PAD. Loss of the Chee device with the cord enclosed will render the PAD inoperable. Another disadvantage associated with the Chee device is that it forms yet another body that must be hand held by the user, left free to hang or attached to the user&#39;s clothing in some fashion to prevent the device from moving with the body movement of the user.  
      Another example of the know art is U.S. Pat. No. 5,984,224 issued to Bill Yang on Nov. 16, 1999 and entitled “Cable-Spooling Casing for Earphones”. One disadvantage of the Yang invention is that it does not permit mounting of a PAD to the spooling device and is worn separate from the PAD.  
      Therefore there exists disadvantages and shortcomings in the known art of which the present invention seeks to overcome.  
     SUMMARY  
      In accordance with one embodiment of the present invention there is provided a base comprising a front plate having a front surface and a back surface, a back plate having a front surface and a back surface, a plate separating body having a top surface and a bottom surface thereby creating a space between the two plates and a spring clip fixed to the top end of the back plate having a top curved surface a biased clip portion adapted to clasp to a wearers belt or pocket and a flared lip adapted to permit easy attachment to a wearer&#39;s belt or pocket. The spring clip is integral to the back plate. There is a plate separating body adapted to create a predetermined distance between the front plate back surface and back plate front surface sufficient so that a cord can be easily wrapped within the space. The cord is wrapped around the separating body in concentric coils. A portable PAD such as an iPod-type device or a small radio is mounted to the front plate front surface by a dual-sided adhesive strip.  
      In another embodiment of my invention an attachment pad such as a dual sided attachment pad using hook and loop mating surface such as sold under the trade-mark VELCRO® can be used to fasten the portable PAD to the base.  
      In yet another embodiment of my invention a self-adhering clear plastic cover is placed over the face of the portable music device to keep it waterproof and clean.  
      In one embodiment of my invention there is a plurality of cutouts in the back plate for holding the cord in place while it is used to hang the base around the neck of the wearer.  
      In another embodiment of my invention the back plate has a front surface and a back surface. The front surface of the back plate includes two stubs and that are adapted to press fit into recesses on the back surface of the front plate. Once the back plate is joined to the front plate the raised discs create a space between the front surface of the back plate and the back surface of the front plate sufficiently wide to accommodate the diameter of excess cord wrapped around the two raised discs. This embodiment is particularly suited for manufacturing the front and back plates using thermoplastics and injection molding techniques.  
      In still another embodiment of my invention there is included a left side bracket, a right side bracket and a bottom bracket. This embodiment is adapted to hold a portable PAD that is augmented with an amplifier module for powering, for example, head phones. The module includes a volume control dial and a port for inserting an audio plug.  
      In still another embodiment of my invention an amplifier and battery module is mounted to a bottom bracket on the front plate. The module may include a microphone, a thumbwheel for volume control, a three-way toggle switch having a first position corresponding to the amplifier on, a second position corresponding to the amplifier off and a third position corresponding to the amplifier on/microphone on so that the wearer can hear ambient sounds or a conversation. The portable music device docks with a post on the module and thereby connects its internal power source with the module supplementary battery. A standard USB port can also be provided in the module.  
      In one embodiment of my invention the base is sold separately apart from the portable PAD. However, another embodiment of my invention has the portable PAD sold as a kit including the base and clear cover.  
      In another embodiment of my invention the base comprises a first pod and a second pod. The second pod is disposed from the first pod by a flat plate. The two pods and the flat plate are molded as one piece from suitable thermoplastic materials. A spring clip is attached to the back surface of each pod to adhere to the wearer in a variety of orientations.  
      In still another embodiment of my invention a loop can be used to mount the base and portable music device combination to a waist belt.  
      In another embodiment of my invention, the two pods have removable front surfaces that enclose a chamber. The chamber can be used to contain additional batteries, small radio circuits and amplification devices to power head phones. These devices can be operatively connected to an iPod-type device through a docking post. The first pod and second pod have recessed front surfaces creating ridges around the first and second pods so that an iPod-type device will sit on the recessed front surfaces and adhere to them using double-backed adhesive pads. The ridges prevent the portable PAD from slipping off of the base in an up, down or sideways direction. The portable PAD can be fixed to the base using cinctures, elastic bands, VELCRO® straps, and clamps or placed in a casing that is in-turn fixed to the base. Two portable PADs may be attached to the base by fixing one to the front surface and one to the back surface of the base using double-backed adhesive pads and cinctures.

     DETAILED DESCRIPTION  
      Referring to  FIG. 1 , there is shown a typical portable PAD ( 10 ), such as an iPod®, fixed to the apparel ( 12 ) of the wearer ( 14 ). The portable PAD comprises a player body ( 16 ) containing internal power means (not shown), internal amplification means (not shown), digital music processing means (not shown) a display ( 18 ) and a control pad ( 20 ). A cord ( 22 ) attaches a listening device ( 24  &amp;  26 ) such as or earphones (shown in  FIG. 1 ) or full-sized headphones (shown in  FIG. 18 ). The cord ( 22 ) comprises a first wire ( 30 ) having a first end ( 32 ) and a second end ( 34 ) and a second wire ( 36 ) having a first end ( 38 ) and a second end ( 40 ). Attached to the first end ( 32  &amp;  38 ) of each wire ( 30  &amp;  36 ) is, as shown in  FIG. 1 , a listening device such as an earphone ( 24  &amp;  26 ) for insertion into the wearer&#39;s ears ( 46  &amp;  48 ). The cord ( 22 ) transmits electrical signals from the portable PAD to the earphones or headphones. The second ends ( 34  &amp;  40 ) of the two wires ( 30  &amp;  36 ) are attached to an audio plug ( 42 ) adapted for connecting the listening devices to the portable PAD ( 10 ). The cord ( 22 ) comprises the first wire and the second wire bound together in a parallel configuration over a first cord length ( 44 ) extending from the audio plug ( 42 ) to a point of bifurcation ( 45 ). At the point of bifurcation, the cord splits into two wires running to each sound device. As  FIG. 1  illustrates the cord is adapted to fit a wide range of heights of wearers. For taller individuals, the cord length is sufficient to reach the ears ( 46  &amp;  48 ) of the wearer without a large excess of cord hanging down from the ears. As previously mentioned, for shorter individuals there may be a large length of cord that is excess to the required length to reach the ears of the wearer. This cord can cause distractions and get snagged in body movements thereby dislodging the listening device. Users may wear the PAD at belt height as shown or elect to clip it to an armband or shirt-pocket, thereby exacerbating the excess-cord problem. Therefore, to resolve this problem, my invention is adapted to conveniently store the excess cord length so that it does not encumber the wearer.  
      The preferred embodiment of my invention ( 50 ) is illustrated in  FIG. 2   a  to  FIG. 2   c . In  FIGS. 2   a  to  2   c  my invention comprises a base ( 52 ) comprising a front plate ( 54 ) having a front surface ( 56 ) and a back surface ( 58 ), a back plate ( 60 ) having a front surface ( 62 ) and a back surface ( 64 ), a plate separating body ( 66 ) having a top surface ( 68 ) and a bottom surface ( 70 ) creating a space ( 72 ) between the two plates and a spring clip ( 74 ) fixed to the top end ( 76 ) of the back plate ( 60 ) and having a top curved surface ( 78 ) a biased clip portion ( 80 ) adapted to clasp to a wearer&#39;s belt or pocket and a flared lip ( 82 ) adapted to permit easy attachment to a wearers belt or pocket. The spring clip in this embodiment is integral to the back plate ( 60 ). The separating body may have curved top and bottom surfaces as illustrated or flat top and bottom surfaces. The plate separating body ( 66 ) is adapted to create a distance ( 84 ) between the front plate back surface ( 58 ) and back plate front surface ( 62 ) sufficient so that a cord can be easily wrapped within the space ( 72 ). The cord is wrapped around the separating body ( 66 ) in concentric coils. Portable PAD ( 88 ) is mounted to the front plate ( 54 ) front surface ( 56 ) by a dual-sided adhesive strip ( 90 ). In another embodiment an attachment pad such as a dual sided piece of VELCRO® having a hook side and a loop side can be used to fasten the portable PAD ( 88 ) to the base ( 52 ). In the preferred embodiment my invention includes clear plastic cover ( 92 ) that is self-adhering to the face ( 94 ) of the PAD ( 88 ) to protect it while permitting viewing of the display screen ( 96 ) and manipulation of the control pad ( 98 ).  
      Referring to  FIG. 2   c , there is illustrated a view of the front surface ( 62 ) of the back plate ( 56 ) of this embodiment of the base showing additional features. The separating body ( 66 ) has a width ( 100 ) and a length ( 102 ) and is disposed centrally on the surfaces ( 58 ) and ( 62 ) of the front and back plates. The length and width of the separating body is such that there is sufficient area between the front and back plates to accommodate a desired length of cord wrapped around the separating body. The spring clip ( 80 ) extends approximately halfway down the back surface ( 64 ) of the back plate ( 60 ). View  2   c  illustrates a plurality of cutouts in the back plate ( 60 ). First cutout ( 110 ) is located at the bottom end ( 112 ) of the back plate and to the left of the separating body ( 66 ). The first cutout extends upwards to a point ( 114 ) that is above the bottom curve ( 70 ) of the separating body. The second ( 116 ) and third ( 118 ) cutouts are disposed opposite each other across the separating body ( 66 ). Cutout ( 116 ) extends from the left side ( 120 ) of the back plate to a point ( 122 ) adjacent to the separating body. Cutout ( 118 ) extends from the right side ( 124 ) of the back plate to a point ( 126 ) adjacent to the separating body. Cutouts ( 116 ) and ( 118 ) are located a distance ( 130 ) from the bottom ( 112 ) of the back plate which is about three-quarters the way up the back plate. Cutouts ( 132 ) and ( 134 ) are disposed opposite each other at the top end ( 76 ) of the back plate at the point ( 136 ) where the clip ( 74 ) is attached to the back plate. The depth ( 140 ) of each of the cutouts ( 132 ) and ( 134 ) is approximately twice the diameter of the cord held within the base.  
      Referring now to  FIG. 3  there is illustrated another embodiment of the back plate of my invention ( 150 ) wherein the back plate ( 152 ) has a front surface ( 154 ) and a back surface ( 156 ). The back surface ( 156 ) includes two stubs ( 160 ) and ( 162 ) that are adapted to press fit into recesses ( 164 ) and ( 166 ) penetrating raised discs ( 168 ) and ( 170 ). Once the back plate ( 152 ) is jointed to the front plate ( 172 ) the raised discs create a space between the front surface ( 154 ) of the back plate and the back surface ( 174 ) of the front plate sufficiently wide to accommodate the diameter of excess cord wrapped around the two raised discs. This embodiment is particularly suited for manufacturing the front and back plates using thermoplastics and injection molding techniques. The positioning of the clip ( 176 ) and the cutouts ( 178 ,  180 ,  182 ,  184  and  186 ) is the same as the embodiment shown in  FIG. 2 . In this embodiment there is included a gripping bar ( 185 ) that has a serrated edge for better gripping the apparel of the wearer.  
      Referring now to  FIG. 4 , there is shown a view of the back surface ( 64 ) of the back plate ( 60 ) of the embodiment shown in  FIG. 2 . Audio plug ( 42 ) is shown in the position where it would connect with the portable PAD ( 94 ) in  FIG. 2 . Cord ( 202 ) runs from the audio plug and enters space ( 72 ) between the front and back plates at the top end ( 114 ) of first cutout ( 110 ). The top end ( 114 ) of the first cutout is a pinch-point that holds the cord tightly so as to reduce the tension on the audio plug. The cord ( 202 ) wraps around the separating body ( 66 ) and then exits the space ( 72 ) at cutout ( 118 ). Pinch-point ( 126 ) secures the cord. The cord then runs under the clip ( 74 ) and exits from the clip. From there the cord wraps around the neck of the wearer and returns to the clip where it crosses itself at point ( 204 ) and re-enters space ( 72 ) at cutout ( 116 ) behind the clip. The cord wraps around the separation body and exits the space at point ( 206 ) whereupon it travels to the listening device. This manner of using the cutouts to pinch the cord in a plurality of places secures the cord as a lanyard that is able to carry the weight of the combined base and portable PAD.  
      Alternatively (not illustrated here but evident in  FIG. 8 ), the cord may continue routing up within space ( 72 ) and out through slot ( 134 ) whereupon it is pinched and runs horizontally under clip ( 74 ) towards its opposite end, whereupon it exits and travels to the listening device. This manner of using the cutouts to pinch the cord secures the free end of the cord where it exits the spool, thereby preventing inadvertent uncoiling. Slots  134  and  132  may have somewhat different widths, each width being sized to securely pinch a standard cord diameter. For example: common cord diameters are 2 and 3 millimeters so slot widths of 1.75 millimeters and 2.75 millimeters might be chosen in order to provide adequate pinching action onto such cords. Serrated slots, V-shaped slots and/or multiple slots on each side of the backplate may be used to secure a wider range of cords (cord-pinching slots adapted to fit different cords are shown in  FIG. 25 ).  
      Referring now to  FIG. 5 , there is illustrated a side view of the same embodiment of my invention as illustrated in  FIG. 4 . Portable PAD ( 210 ) is shown mounted to the front surface ( 56 ) of the front plate ( 54 ) by way of a double backed adhesive fastener ( 90 ) between the back surface ( 212 ) of the portable PAD and the front surface ( 56 ) of the front plate. Audio plug ( 42 ) is inserted into the portable PAD. Spring clip ( 74 ) is illustrated mounted to the top ( 76 ) of back plate ( 60 ). Cord ( 202 ) enters space ( 72 ) at point ( 114 ) and travels around the separating member exiting at cutout ( 118 ). The cord travels around the neck of the wearer, crosses over itself at point ( 204 ) and re-enters space ( 72 ) at cutout ( 116 ) travels down the side of the separating member facing the viewer, around the opposite side of the separating body and then out to the listening device at the end of wire ( 230 ).  
      Now referring to  FIG. 6  and  FIG. 7 , there is shown another embodiment of my invention ( 300 ) in oblique and side views respectively. This embodiment of the invention comprises a front plate ( 302 ) having a front surface ( 304 ) and a back surface ( 306 ), a back plate ( 308 ) having a front surface ( 310 ) and a back surface ( 312 ), a spring clip ( 314 ), a left side bracket ( 316 ), a right side bracket ( 318 ) and a bottom bracket ( 320 ). Spring clip ( 314 ) is fixed to the top end ( 322 ) of the back plate ( 308 ). The back plate ( 308 ) includes the same five cutouts as the embodiment shown in  FIG. 4  with only cutout ( 324 ) and cutout ( 326 ) visible in this  FIG. 6 . This embodiment is adapted to hold a portable PAD ( 330 ) that is augmented with an auxiliary electronics module ( 332 ) which contains, for example, a high quality amplifier for powering head phones. Other complementary electronics hardware may be contained within said module, for example: auxiliary batteries, auxiliary FM radio, auxiliary radio transmitter for broadcasting to a nearby car radio etc. The electronics module ( 332 ) communicates with the PAD ( 330 ) via a mating dock connector (hidden in this view). The module includes a volume control dial ( 334 ) and a port ( 336 ) for inserting an audio plug. The left side bracket ( 316 ) and the right side bracket ( 318 ) are mounted and integral to the left ( 336 ) and right ( 338 ) sides respectively of the front plate ( 302 ) so that their respective concave sides ( 340 ) and ( 342 ) face each other. The brackets are shaped to generally conform to the shape of the sides and of the portable PAD. The front edges ( 348 ) and ( 350 ) of each side curve slightly inwards so that they contain the front surface ( 350 ) of the portable PAD and prevent is from toppling out of the base. In this embodiment, the bottom bracket ( 320 ) of the front plate extends from the bottom edge ( 322 ) of the front plate ( 302 ). The shape of the bottom bracket is adapted to the shape of the module ( 332 ) with the front edge ( 352 ) of the bottom bracket curved upwards to contain the front surface ( 354 ) of the module so that it does not slip out of the bottom bracket. The side brackets possess a suitable amount of resiliency so that when the portable PAD is inserted between them they are in a secure grasping contact with the sides of the portable PAD.  
      Referring now to  FIG. 8 , there is shown yet another embodiment of my invention ( 400 ) comprising a front plate ( 402 ) having a front surface ( 404 ) and a back surface ( 406 ), a back plate ( 408 ) having a front surface ( 410 ) and a back surface ( 412 ), a spring clip ( 414 ), a left side bracket ( 416 ), a right side bracket ( 418 ) and a bottom bracket ( 420 ). In this embodiment there is mounted to the top surface ( 422 ) of the bottom bracket ( 420 ) an amplifier and battery module ( 424 ). The module ( 424 ) includes a microphone ( 426 ), a thumbwheel ( 428 ) for volume control, a three-way toggle switch ( 430 ) having a first position corresponding to the amplifier on, a second position corresponding to the amplifier off and a third position corresponding to the amplifier on/microphone on so that the wearer can hear ambient sounds or a conversation without have to remove the earphones. Other control modes may be implemented, for example: to permit recording sounds from the microphone into the memory of the portable music device. The PAD ( 432 ) docks with post ( 434 ) and thereby connects any electronic circuits that are required between the two modules. A standard USB port ( 436 ) is also illustrated so that the wearer can dock the invention/portable PAD combination with a computer for downloading additional music. The USB port also acts to charge both the internal power source of the portable PAD as well as the supplemental battery contained in the module.  
      Referring back to  FIG. 2   a  to  2   c , one embodiment of my invention ( 50 ) is sold separately apart from the portable PAD ( 94 ). However, another embodiment of my invention has the portable PAD is sold as a kit including the invention ( 50 ).  
      Referring to  FIG. 9  and  FIG. 10 , there is shown another embodiment of my invention ( 400 ) front oblique view and side view respectively. My invention comprises a base ( 402 ) onto which the portable PAD ( 404 ) is mounted. The portable PAD has a display screen ( 406 ) and control pad ( 410 ) and other well-known features normally associated with such devices. The portable PAD has a listening device (not shown) that is attached to the portable music device by way of cord ( 412 ) and audio plug ( 414 ). As more fully explained below, the wearer can spool excess cord ( 416 ) around the flat plate ( 418 ) in a convenient and expedient manner. The base ( 402 ) comprises a first pod ( 420 ) having a first vertical axis ( 422 ) and a second pod ( 424 ) having a second vertical axis ( 426 ). The second pod ( 424 ) is disposed from the first pod ( 420 ) a predetermined distance ( 428 ) such that the first vertical axis ( 422 ) and the second vertical axis ( 426 ) are co-axial. There is also a flat plate ( 418 ) having a third vertical axis ( 430 ). The flat plate has a length equaling the predetermined distance ( 428 ) and joins the first and second pods as illustrated. The two pods and the flat plate are molded as one piece from suitable thermoplastic materials. Also shown in  FIG. 9  is one embodiment for mounting the portable PAD ( 410 ) to the base ( 402 ). In the  FIGS. 9 and 10 , the portable PAD is mounted to the base by at least one cincture ( 432 ) comprising one of an elastic band, a VELCRO® band or a preformed and resilient plastic band. The cincture ( 432 ) is adapted to wrap around the base ( 402 ) and the portable PAD ( 404 ) thereby holding the portable PAD securely to the base. As further explained below there are other means possible to couple the portable PAD to the base. Means to couple the combined base and portable PAD to the wearer comprise at least one spring clip ( 434 ) that is adapted to fasten to the waist belt or pocket of the wearer. As illustrated in  FIG. 10 , there can be 2 such spring clips ( 434 ) and ( 436 ) so that the combined base and portable PAD can be mounted and oriented in a variety of positions. The spring clips are fastened to the back surface ( 438 ) of the first pod ( 420 ) and the back surface ( 440 ) of the second pod ( 424 ) by fixed or pivoting fastening means ( 442 ) such as screws, pins or rivets or by suitable adhesives. In another embodiment of my invention the spring clips may be removable from the back surface of the two pods. The spring clips advantageously attach to an arm band of the wearer so that the portable PAD can be worn during active sports or exercise.  
      Referring to  FIG. 11  there is shown another embodiment of my invention ( 450 ) in which means to fasten the invention to the wearer comprises a loop ( 452 ) fixed to the top surface of the base ( 456 ) by fixing means such as a screw or rivet ( 458 ). The loop is adapted to be threaded onto the waist belt of the wearer. In this embodiment a first PAD ( 455 ) is attached to one side of the base and a second, complementary PAD ( 454 ) is attached to its opposite side.  
      Referring now to  FIG. 12   a  to  12   c , there is shown additional detail of the base ( 456 ) of my invention ( 450 ) illustrated in  FIG. 11  without belt loop ( 452 ).  FIG. 12   a  shows the base in an elevation side view.  FIG. 12   b  shows a top view of the base and  FIG. 12   c  shows a front view of the base. The base comprises a first pod ( 460 ), second pod ( 462 ) and flat plate ( 464 ) joined so that their respective axis ( 466 ,  468  and  470 ) are co-axial. The first pod ( 460 ) comprising a back surface ( 472 ), a front surface ( 474 ), a left side ( 476 ), a top side ( 478 ), a right side ( 480 ) and a bottom side ( 482 ). The top side ( 478 ) is joined to left side ( 476 ) and right side ( 480 ) by curved shoulders ( 477 ) and ( 479 ) respectively. The second pod ( 462 ) comprises a back surface ( 488 ), a front surface ( 490 ), a left side ( 492 ), a top side ( 494 ), a right side ( 496 ) and a bottom side ( 498 ). The second pod left side ( 492 ) and right side ( 496 ) are joined to the bottom side ( 498 ) by way of curved shoulders ( 501 ) and ( 503 ) respectively.  
      Still referring to  FIG. 12 , the flat plate ( 464 ) has a length ( 462 ), a width ( 506 ), a thickness ( 508 ), a front flat surface ( 510 ), a back flat surface ( 512 ), a top end ( 514 ), a bottom end ( 516 ), a left side ( 518 ) and a right side ( 520 ). The top end ( 514 ) of the plate is fixed to the bottom side ( 482 ) of the first pod and the bottom end ( 516 ) of the plate is fixed to the top side ( 494 ) of the second pod. The front surfaces ( 474  and  490 ) and the back surfaces ( 472 ) and ( 488 ) of the first and second pods are co-planer.  
      The width ( 506 ) of the flat plate ( 464 ) is slightly less than the widths of the first ( 460 ) and second ( 462 ) pods so that when a cord is spooled around the flat plate, the outer surface of the cord does not extend past the left and right sides of the pods. This can be seen in FIGS.  9  to  11 . Similarly, the thickness ( 468 ) of the flat plate is such that when the cord is spooled around the flat plate the outer surface of the cord does not extend beyond the front and back surfaces of the first and second pods.  
      Referring to  FIG. 10 , if the excess cord ( 416 ) wrapped around the flat plate ( 418 ) is too thin to frictionally engage the back ( 417 ) of the portable PAD ( 404 ), “O” rings ( 419 ) can be used to increase the thickness of the cord so that it is held tightly in a spooled configuration around the flat plate.  
      Referring now to  FIG. 13 , there is shown another embodiment of my invention ( 600 ). The base ( 602 ) comprises a first pod ( 604 ) having a vertical axis ( 612 ) a second pod ( 606 ) having a vertical axis ( 616 ) and a flat plate ( 608 ) having a vertical axis ( 614 ) and length ( 610 ) and disposed between the first and second pods such that their respective vertical axis ( 612 ), ( 614 ) and ( 616 ) are co-axial. The first pod ( 604 ) has a top surface ( 620 ), a left side ( 622 ), a right side ( 624 ), a bottom side ( 626 ), a back surface ( 628 ) and a removable front surface ( 630 ). The left side ( 622 ) and right side ( 624 ) of the first pod ( 604 ) are joined to the top side ( 620 ) by curved shoulders ( 632 ) and ( 634 ) respectively. As illustrated, the top, bottom, left and right sides and the back surface of the first pod forms a chamber ( 636 ). Removable front surface ( 630 ) of the first pod is configured to the profile of the first pod and is sealably placed over the mouth of the chamber ( 636 ) to protect contents against moisture and dirt. In the embodiment shown in  FIG. 13 , chamber ( 636 ) is adapted to contain amplification apparatus ( 638 ) and control apparatus ( 640 ) having switch ( 642 ) and a volume control knob ( 644 ). In this embodiment a pair of headphones can be plugged into the amplifier by way of plug ( 646 ). It is well known that in order to provide a good quality of sound to a set of headphones amplification is required of the audio signal generated by the portable PAD. Therefore, this embodiment of the base of my invention is able to accommodate the apparatus necessary to use larger and more comfortable high impedance headphones in lieu of earphones commonly provided with portable PADs. In yet another embodiment of my invention, it is possible to place a FM radio receiver in chamber ( 636 ). In still another embodiment of my invention it is possible to place a microphone in chamber ( 636 ) to facilitate recording of the wearer&#39;s environment where the portable PAD is adapted for recording. Button switch ( 642 ) can be used to switch from the portable PAD to the radio or to the microphone and recording device as desired. A signal processor could be included in chamber ( 636 ) to filter out extraneous environmental noise when listening to music or human speech. In another embodiment, chamber ( 636 ) can be used to store earphones.  
      Still referring to  FIG. 13 , the second pod ( 606 ) comprises a top surface ( 650 ), a right side ( 652 ), a left side ( 654 ), a bottom ( 656 ), a left shoulder ( 658 ) and a right shoulder ( 660 ). The second pod also has a back surface ( 662 ) and a removable front surface ( 664 ). The rear surface, top, bottom, left and right sides form a chamber ( 668 ) adapted, in this embodiment, to store additional batteries ( 670 ) and ( 672 ). The front surface ( 664 ) is adapted to seal the mouth of the chamber against moisture and dirt. In this embodiment the base ( 602 ) includes a docking apparatus ( 676 ) that is adapted to couple with the portable music charging receptacle (not shown) by way of plug ( 678 ). The batteries are used to power the amplifier ( 638 ) and extend the playing time of the portable PAD. The batteries are operatively connected to the amplifier by means of a suitable connector (not shown) embedded into the flat plate ( 608 ). The amplifier is connected to the listening device output plug on the portable PAD. This connection can be integrated into plug ( 678 ) with suitable connectors placed within the flat plate.  
      Still referring to  FIG. 13 , first pod front surface ( 630 ) and second pod front surface ( 664 ) are adapted to abut seat ( 680 ) and ( 682 ) respectively so that the front surfaces are recessed below pod edges ( 684 ) and ( 686 ). This creates a raised ridge ( 688 ) and ( 690 ) around front surfaces of the first and second pod which are adapted to receive the back surface of the top and bottom portion of the portable PAD. The result is that, once the cincture is in place, the portable PAD is prevented from slipping off of the base in an up, down or sideways direction.  
      Referring to  FIG. 14 , there is shown a view of one embodiment my invention ( 700 ) showing how the portable PAD ( 702 ) fits into the raised ridges ( 704 ) and ( 706 ) of the first and second pods ( 708 ) and ( 710 ) respectively. A desired length of excess cord ( 712 ) is spooled around the flat plate ( 714 ). Double sided adhesive pads ( 716 ) and ( 718 ) are used to fix the back surface ( 720 ) of the portable PAD ( 702 ) to the front surface ( 722 ) and ( 724 ) of each pod. Once the portable music device is placed within the raised ridges a cincture ( 726 ) is then placed over the combined base and portable PAD to hold the latter firmly against the former.  
      Referring now to  FIG. 15   a  to  15   c , there is illustrated three additional means to fix the portable PAD ( 800 ) to the base ( 802 ) of my invention.  FIG. 15   a  shows that two identical cinctures ( 804 ) and ( 806 ) can be used.  FIG. 15   b  shows the use of four “L” shaped clamps ( 808 ), ( 810 ), ( 812 ) and ( 814 ). The clamps are made from a resilient material such as plastic and are fixed to the base by way of a pivoting fastener ( 816 ). The pivoting fastener allows a limited amount of movement of the clamp so that the portable PAD can be easily coupled to the base. Once the portable PAD is placed over the base, the clamps are flexible enough to be able to engage the top surface ( 818 ) of the portable PAD in a grasping fashion.  
      Referring to  FIG. 15   c  there is shown another embodiment of my invention wherein the means to hold the portable PAD ( 800 ) to the base ( 802 ) comprises a flexible casing ( 820 ) adapted to tightly encase the portable PAD. The flexible casing has a first rectangular window ( 822 ) adapted for viewing the control display of the portable PAD and a second circular window ( 826 ) adapted for viewing the control pads of the portable PAD. Once the portable PAD is inserted into the flexible casing, the casing is mounted by a pair of VELCRO® straps ( 828 ) and ( 830 ).  
      Referring now to  FIGS. 11 and 16  there is shown another embodiment of the invention ( 840 ) in which the base ( 842 ) is coupled to the wearer using a belt loop ( 844 ). In this embodiment it is possible to attach two portable PADs to the same base. In this  FIG. 16 a  small FM radio ( 846 ) and an iPOD-type device ( 848 ) are attached to the front ( 852 ) and back ( 854 ) surfaces of the base respectively. The iPOD-type device ( 848 ) is fastened to the front surface ( 852 ) of the base in the same manner as that shown in  FIG. 14 . The radio is fastened to the back surface ( 854 ) using a double-sided adhesive pad ( 860 ). Cincture ( 862 ) is large enough to fit over the base, the iPOD-type device and the radio. In order to listen to the radio, the wearer has only to unplug the audio plug ( 864 ) from the iPOD-type device and plug it into the radio. Alternatively, a “Y” connection can be used to simultaneously connect both devices to the listening device and one can be chosen over the other by turning the undesired device off and the desired device on. Excess cord is spooled around the flat plate ( 864 ).  
      Referring now to  FIG. 17 , my invention ( 870 ) can be hung around the neck of the wearer using the cord ( 872 ) as a lanyard. A first coil is of excess cord is spooled around the flat plate and then the lanyard ( 874 ) is formed around the neck ( 876 ) of the wearer ( 878 ). The remaining excess cord is spooled tightly around the flat plate of the base so that the lanyard retains its diameter.  
      Referring now to  FIG. 18 , there is shown the same embodiment as  FIG. 16  using two portable PADs such as a radio ( 880 ) and an iPOD-type device ( 882 ). The iPOD-type device is attached to the front surface of the base ( 884 ) and the radio is attached to the back of the base. The combined apparatus is attached to the wearer by belt loop ( 886 ). In this embodiment the wearer is using a set of headphones ( 888 ). Typically such headphones come with a very long cable ( 890 ) that is too long to be spooled around the flat plate. In this embodiment, the excess cable can be hung as concentric loops ( 892 ) from the cavity ( 894 ) created by coupling the base to the portable PADs. In this mode, the length of the cord required between the portable PAD and the headphones can be increased by gently pulling on the cord. This will cause the cord loops to contract if additional cord is required. Alternatively, the user can easily thread excess cord back into the cavity thereby expanding the loops. As previously mentioned, the use of large headphones may require the installation of a small amplifier and additional power in the chambers of the base.  
      Referring now to  FIGS. 19   a  and  19   b  there is shown in  FIG. 19   a  one embodiment of my invention ( 900 ) mounting a PAD ( 902 ) combined with an amplifier ( 903 ) and clipped to a belt ( 904 ). In  FIG. 19   b , it is illustrates that multiple PADs ( 906 ) and ( 908 ) can be mounted to the belt ( 904 ) of the wearer.  
      Also apparent in  FIG. 19   a  is the use of a back plate ( 60 ) having no slots. The non-slotted embodiment has a large enough spool width ( 84 ) that a small diameter earphone cord may be spooled without the need for access via a side-slot (i.e. the cord&#39;s diameter is less than half of the spool&#39;s width). The iPod-like device ( 902 ) and its auxiliary headphone amplifier ( 903 ) are secured using double-sided tape. Also apparent in  FIG. 19   b  is the extra-wide spool width ( 84 ) can accommodate a single coil of the thick headphone cord of a high quality headphone. Since the iPod-like device ( 908 ) and its companion PAD ( 906 ) are clipped adjacent to each other on belt ( 904 ), a long and thick headphone cord may be coiled around the combined exterior of their respective cord spools (in a similar manner to that shown in  FIG. 18 ).  FIG. 19   b  illustrates companion PAD  906  as a headphone amplifier other modules, such as an extended battery pack may be substituted or added to the interconnected array of PADs.  
      Referring now to  FIG. 20  there is shown an exploded diagram of another embodiment of the invention ( 1000 ) comprising the following components for mounting a PAD ( 1002 ): a back plate ( 1004 ) having an integral clip ( 1006 ), a front surface ( 1008 ) and a back surface ( 1010 ); a front plate ( 1012 ) having a front surface ( 1014 ), a back surface ( 1016 ), a first flange ( 1018 ) and a second flange ( 1020 ) wherein the first and second flanges have an outside surface ( 1022 ) and an inside surface ( 1024 ), an edge ( 1025 ) and a notch ( 1027 ) in each flange. The front plate further includes a first cutout ( 1026 ) and a second cutout ( 1028 ). A first attachment pad ( 1030 ) has a back adhesive surface ( 1032 ) adapted to adhere to the front surface ( 1014 ) of the front plate ( 1012 ) and a front hook or loop mating surface ( 1034 ) such as Velcro® to mate to a second attachment pad ( 1036 ) having a back corresponding hook or loop mating surface ( 1040 ) such as Velcro® and a front adhesive surface ( 1038 ) adapted to adhere to the back surface ( 1042 ) of the PAD ( 1002 ). The first and second attachment pads may also have cutouts ( 1050 ) and ( 1052 ) that correspond to cutouts ( 1026 ) and ( 1028 ) and are adapted to overlay the same. The pads are also dimensioned so that they fit within the front panel and between the adjacent flanges so that there is a narrow space between the edge of the pads and the inside surfaces of the flanges. The narrow space accommodates the cord once it is forced through gap ( 1066 ) as explained below. Adhered to the front surface ( 1046 ) of the PAD ( 1002 ) is an optional transparent adhesive membrane ( 1044 ) such as Scotchguard® Paint Protection Film SGPPF6 adapted to enhance the durability of the face of the PAD.  
      Referring now to  FIG. 21  there is shown an assembled rear view of the same embodiment of the invention ( 1000 ) as  FIG. 20 . In its assembled form back plate ( 1008 ) is separated from the front plate ( 1012 ) by a separating member such as illustrated as item ( 168 ) in  FIG. 3  but not shown in this  FIG. 21 . Between the front plate and the back plate is a gap ( 1060 ) within which the cord ( 1062 ) is spooled around the separating member. The cutout ( 1026 ) and the optional overlapping cutouts in the attachment pads ( 1050 ) create a deep notch in which the cord ( 1062 ) is embedded so that it does not interfere with the cord attached to the jack plug ( 1064 ) as successive coils are wound into the spool. Cutout ( 1028 ) ( FIG. 20 ) at the top of the front plate has the same purpose and permits the PAD to be mounted either upright as shown here or inverted. The shortened cord ( 1062 ) is hidden inside the front plate ( 1012 ) and placed adjacent to the inside surface ( 1024 ) of the flange ( 1018 ) by forcing it through gap ( 1066 ). Gap ( 1066 ) is able to open sufficiently wide to accommodate the diameter of the cord and then close again after the cord is forced in the gap because Velcro® attachment pads create a limited amount of elastic flexure. Once the cord is placed behind the flange the cord is fixed within the narrow gap between the edge of the Velcro® pads and the inside surface of the flange and will not move so that the spooled cord within gap ( 1060 ) will not unravel. The notches ( 1027 ) in the flanges also accommodate fixing the cord within the gap ( 1060 ). The cord can be forced into the gap ( 1066 ) and then exit from notch ( 1027 ) thereby more finely adjusting the length of the cord available for the ear listening device. The notch also grabs the cord thereby preventing cord spooled within the gap ( 1066 ) from unraveling.  
      Also illustrated in  FIG. 21  is an alternative manner in which to secure the cord ( 1062 ) within the gap ( 1060 ) comprising a compressible foam block ( 1090 ) having a slit ( 1092 ) and a hole ( 1094 ) at its centre. Instead of forcing the cord through the gap ( 1066 ) the block ( 1090 ) is placed around the cord so that it sits within the hole and then compressed so that it fits within the gap ( 1060 ) as shown at ( 1096 ). Once the block with cord is in the gap the foam block will exert biasing forces on the front of the back plate and back of the front plate such that it will not move.  
      Referring now to  FIG. 22  there is shown yet another embodiment of the invention ( 1070 ). In this embodiment plate ( 1072 ) is mounted directly to the back surface ( 1074 ) of the PAD ( 1076 ). Separating members ( 1078 ) and ( 1080 ) are integral to the PAD back surface and the plate and create a gap ( 1082 ) within which cord can be spooled around the separating members. Alternatively the separating members can be glued or fused to the plate and the PAD back surface.  
      Referring now to  FIG. 23  there is shown another embodiment of the invention ( 1100 ) adapted for use during exercising and other vigorous movement by the wearer ( 1102 ) by the addition of a chest belt ( 1104 ). The PAD ( 1105 ) is mounted to the front plate ( 1106 ) as shown in the embodiment of  FIG. 21  or  FIG. 22 . The rear clip ( 1108 ) fits over the chest belt buckle ( 1110 ) and the weight of the PAD is supported by a lanyard ( 1112 ) around the neck of the wearer. The lanyard supports the weight of the PAD around the neck of the wearer and can be made of a suitable cotton or polyester material for lightweight comfort. Since the belt only serves to prevent pendulous PAD motion, it may be made of a lightweight, elastic webbing material. Buckle ( 1110 ) may include means for belt length adjustment. The buckle is sufficiently rigid to support the PAD and may be elongated to support additional PADs adjacent to the PAD illustrated at ( 1105 ).  
      Referring now to  FIG. 24  there is shown another embodiment of the invention ( 1120 ) used to carry a heavier load ( 1122 ) on the belt ( 1124 ). The load may consist of one or more PADs as illustrated in  FIG. 19  and it may also include headphones ( 1126 ) attached to an extra long cord ( 1128 ). The belt buckle ( 1130 ) is made robustly to support the heavy PAD and to firmly secure clip(s) ( 1132 ). Lanyard ( 1134 ) threads through the clip(s) ( 1132 ) and provides additional support to the PAD around the neck of the wearer ( 1136 ). To securely and efficiently manage the extra cord length from the headphones ( 1126 ) the headphone cord ( 1128 ) is wrapped around the neck of the user adjacent to the lanyard ( 1134 ). The headphone cord is secured to the lanyard using a plurality of cord wraps ( 1140 ) that can be tightly closed using attachment strips such as Velcro® hook and loop strips mounted to their inside and outside edges respectively for mating. The cord wraps may also be made from a spiral material adapted to keep the bundled headphone cord and lanyard together or cord looms having individual channels to accommodate the lanyard and the headphone cord. Typically the wearer would place the supporting lanyard around her neck and then the headphone cord, apply the cord wraps and then connect the headphones to the PAD. For active wearer motion, the chest belt ( 1124 ) can be worn with or without the lanyard.  
      Referring now to  FIG. 25  there is shown another embodiment wherein the beltclip is not integral to the spool&#39;s backplate as described previously. Beltclip ( 1150 ) is a detachable beltclip such is commonly used for attaching cell phones to a belt. Such clips include belt-gripping pinchers ( 1151 ) and ( 1152 ) joined though a hinge/spring mechanism ( 1153 ). Fixation knob ( 1154 ) protrudes from backplate ( 1008 ) to selectively engage into gripping flange ( 1155 ) which houses a detent mechanism for rotating the mated parts to an angle that maximizes wearer comfort.  
       FIG. 25  also shows cord pinch slots ( 132 ) and ( 134 ) which enable the user to secure the free end of cord ( 1062 ) as shown in  FIG. 8 . The various slot widths enable different cord diameters to be secured along backplate ( 1008 ) as a convenient alternative to more securely routing the cord inside of flange ( 1018 ).  
      Although the description above contains much specificity, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Thus the scope of the invention should be determined by the appended claims and their legal equivalents.
