DETAILED DESCRIPTION OF THE EMBODIMENTS

(17) The technology disclosed herein is directed toward an optimized cord clip for securing a cord of an audio earphone or headphone device being worn by a user. In particular, an optimized cord clip of the present disclosure includes two ferromagnetic units contained in pockets located within and near opposing ends of a flexible strap. In embodiments of the present technology, the pockets are configured with an outer profile that is substantially square. When the optimized cord clip is properly clasped onto an item of clothing, the square geometry of a proximal side of a pocket forms a rotational interlock with the edge of the hem on a user's shirt or jacket or other item of apparel. The additional leverage provided by the rotationally interlocked arrangement of the two edges (e.g. the proximal side edge of a pocket formed in the strap, situated adjacent to the bottom edge of a hem on the collar of a user's shirt) minimizes the overall movement and rotation of the clip, and therefore the overall movement of the audio cord itself. The reduced movement of the cord results in an enhanced user experience, and increased quality of entertainment.

(18) In some embodiments, the optimized cord clip of the present disclosure includes a dual-channel coupler configured to: (i) couple the audio cord to the strap (which is clasped onto the user's apparel), and (ii) minimize sliding of the cord within the optimized cord clip device to avoid disruption to the user. The optimized design of the cord clip of the present disclosure accomplishes both; it minimizes rotation of the cord clip about a collar (and thereby movement of the cord in the same manner), and further minimizes slipping of the cord that may otherwise lead to displacement or complete dislodgement of an earphone from a user's ear. While embodiments of the present technology are described in connection with earphone and headphone devices, the optimized cord clip technology disclosed herein may also be applied to other cords, strings, cables, etc. that users need secured (e.g. the cord connecting noise-canceling earplugs, or spectacle security cords, etc.).

(19) The optimized cord clip of the present disclosure includes a strap and a coupler, the coupler being able to secure both the strap and a cord of an audio device. FIG. 1A is a schematic of a disassembled cord clip strap, and components enclosed therein in accordance with an embodiment of the disclosed technology. The strap 100 includes a first layer 200 formed with pockets 210 and 220, two fitted cushions 503 and 504 formed with apertures 510 and 520, two ferromagnetic units (e.g. magnetized disks or pellets) 512 and 522, and second layer 300. In some embodiments, ferromagnetic units 512 and 522 may be situated in apertures 510 and 520 of fitted cushions 503 and 504; fitted cushions 503 and 504 may be further situated in pockets 210 and 220 formed in layer 200 of strap 100. A second layer 300 may then be mechanically coupled to first layer 200 such that second layer 300 substantially covers the apertures formed in strap 100 by pockets 210 and 220 of first layer 200, thereby enclosing and securing fitted cushions 503 and 504 and ferromagnetic units 512 and 522 in an interior portion of strap 100. As discussed in more detail below, the fully assembled cord clip is optimized to fold the strap about a pivot point (e.g. the dual-channel coupler) so that opposite ends of strap 100 clasp together around a portion of a user's clothing, held together via magnetic force generated by ferromagnetic units 512 and 522.

(20) In some embodiments, no cushions 503, 504 are used to secure ferromagnetic units 512 and 522 within pockets 210 and 220. In other embodiments the ferromagnetic units are secured without fitted cushions 503 and 504 because the shape of the ferromagnetic units 512 and 522 substantially matches the profile of pockets 210 and 220 respectively. In still further embodiments, one of the ferromagnetic units is magnetized and the other is not.

(21) As illustrated in FIG. 1A, in some embodiments the strap 100 is formed with one or more notches 222 and 333, the notches located substantially near the point about which the strap will bend when in a closed configuration during use. As depicted, notches 222 and 333 are configured to secure a mid-portion of strap 100 within a channel 410 of dual channel coupler 400 of FIG. 1B when the optimized cord clip device of the present disclosure is assembled.

(22) Although FIG. 1A depicts strap 100 being formed with two separate layers, 200 and 300, in some embodiments strap 100 is formed from a single piece of material (e.g. compression mold, etc.). However, in embodiments that employ a multilayer approach, such layers may be coupled together in a variety of methods known in the art (e.g. adhesives, plastic weld, etc.). Indeed, it should be noted that the technology disclosed herein is not limited to the figures and examples provided. As will be appreciated by one of ordinary skill in the art, there are many aspects and modifications that may be made to the optimized cord clips depicted in the figures without departing from the scope of this disclosure. For example, a wide variety of materials may be used in a vast array of sizes in employing this technology. For instance, the strap 100 may include one or more flexible and/or rigid materials well-known in the art (e.g. flexible silicone strap formed with rigid plastic pockets, or a spandex top layer with a suede bottom layer, etc.), and the dual-channel coupler may be formed from a rigid plastic, metal, or other suitable material.

(23) FIG. 1B is a perspective view of a dual-channel coupler in accordance with one embodiment of the disclosed technology. As illustrated, dual-channel coupler 400 is formed with a first channel 410 traversing the thickness dimension, CT, of dual-channel coupler 400 and running in a substantially perpendicular direction to longitudinal axis of second channel 450.

(24) First channel 410 is configured to receive and secure strap 100. In particular embodiments, such as the one depicted, strap 100 is notched, the width dimension of first channel 410 substantially matching the outer width dimension of notched portion of strap 100, and the height dimension of first channel 410 substantially matching the thickness, T.sub.100, of strap 100, the notched portion of strap 100 being defined by the combination of notched portion 222 of first layer 220 and notched portion 333 of second layer 300 when combined to form strap 100. In embodiments, the first channel 410 is formed to substantially match the outer profile of a portion of strap 100 to hold strap 100 in place during use. In particular, width dimensions W.sub.210 of first layer 200 and W.sub.310 and second layer 300 fit (either in a relaxed or compressed state) within first channel 410 of dual-channel coupler 400. Additionally, thickness dimension T.sub.100 of strap 100 fits (either in a relaxed or compressed state) within first channel 410 of dual-channel coupler 400.

(25) In still further embodiments, one or more of first layer 200 and second layer 300 is made of a compressible material (e.g. memory foam, silicone, rubber, spandex, suede, etc.), and the thickness of strap 100 is equal to or greater than the height dimension of first channel 410 before a portion of strap 100 is positioned within first channel 410. When strap 100 is positioned within channel 410, the compressible materials of strap 100 may be compressed by the rigid inside wall of channel 410. In some embodiments, this compression increases the outward force applied to the interior wall of first channel 410, and likewise increases the inward force applied to the portion of the strap 100 in contact with the inside wall of the first channel 410. The increased force increases the friction between strap 100 and first channel 410 in accordance with the well-known equation, Fr=N, where Fr is the resistive force of friction, is the coefficient of friction for the two surfaces, N is the normal or perpendicular force between the two objects. Because friction increases with force, embodiments that employ compressible materials in forming strap 100 may realize further positional security and stability of strap 100 within channel 410. Consequently, greater stability may be realized for the audio cord as well. In some embodiments the first channel 410 is formed with a ridge 412 within first channel 410 to ensure there is sufficient compressive force applied to strap 100 to hold the strap 100 in place when a portion of strap 100 is disposed within the first channel 410.

(26) As illustrated, second channel 450 runs along a distal edge of the coupler 400 in the longitudinal direction substantially orthogonal to first channel 410. As depicted, second channel 450 is partially open and configured to receive an audio cord in a snap-fit manner. In particular, second channel 450 has a diameter, D.sub.450, that substantially matches the diameter of an audio cord. The second channel 450 is also configured with a partially open side having a dimension, C.sub.O, measuring smaller than the diameter of an audio cord. With sufficient force, an audio cord may be pressed into second channel 450 such that the audio cord is held snug in place by the interior wall of second channel 450.

(27) FIG. 2A is a top view of a cord clip in accordance with one embodiment of the disclosed technology, the cord clip depicted in an open configuration. FIG. 2B is a bottom view of the cord clip depicted in FIG. 2A, and FIG. 2C is a side view of the same embodiment of the cord clip, also in an open configuration for clarity of discussion. As illustrated in FIGS. 2A-2C and discussed above in connection with FIG. 1B, dual-channel coupler 400 of cord clip 1000 is configured with a second channel 450 to receive and secure cord 50 in a snap-fit manner. As further illustrated, dual-channel coupler 400 of cord clip 1000 is configured with a first channel 410 to receive and secure strap 100 in a substantially orthogonal direction relative to the longitudinal axis of cord 50 when it is situated in second channel 450. In some embodiments, width dimension W.sub.100 of strap 100 is uniform across the length of the strap 100. In other embodiments, a portion of strap 100 is configured with one or more notches, wherein the width dimension of the strap 100 at the notched portion is smaller than the width dimension W.sub.100 of the remainder of strap 100.

(28) FIG. 3A is a top view of a first layer of a strap used in a cord clip in accordance with one embodiment of the disclosed technology. FIG. 3B is a top view of a second layer of a strap used in a cord clip in accordance with one embodiment of the disclosed technology. As depicted, in some embodiments the outer profile of first layer 200 matches the outer profile of second layer 300. In this embodiment, width dimension W.sub.200 of first layer 200 is approximately the same as width dimension W.sub.300 of second layer 300; width dimension W.sub.210 of notched portion of first layer 200 is approximately the same as width dimension W.sub.310 of notched portion of second layer 300; and length dimension L.sub.200 of first layer 200 is approximately the same as length dimension L.sub.300 of second layer 300. In embodiments the width dimensions W.sub.200 and W.sub.300 is about between 15 and 25 millimeters, and the length dimensions L.sub.200 and L.sub.300 is about between 65 and 75 millimeters.

(29) FIG. 4A is a magnified side view of a dual channel coupler component of an optimized cord clip in accordance with one embodiment of the disclosed technology. FIG. 4B is a perspective view of a dual channel coupler component of an optimized cord clip in accordance with one embodiment of the disclosed technology. As depicted, dual-channel coupler 400 is formed with a first channel 410 traversing the thickness dimension, CT, of coupler 400 and running in a substantially perpendicular direction to second channel 450; second channel 450 running along a distal edge of dual-channel coupler 400 in a substantially longitudinal direction.

(30) First channel 410 is configured to receive and secure strap 100. Interior wall 411 of first channel 410 may be configured to substantially match an outer profile of a portion of strap 100 when strap 100 is situated within first channel 100 as depicted in FIGS. 2A-2C. In particular, width dimensions W.sub.210 of first layer 200 and W.sub.310 and second layer 300 are collectively less than or equal to the thickness dimension of first channel 410 of dual-channel coupler 400 when strap 100 is situated within channel 410. In other words, the thickness dimension T.sub.100 of strap 100 fits (either in a relaxed or compressed condition) within first channel 410 of dual-channel coupler 400.

(31) When the strap 100 is positioned within channel 410, the compressible materials of strap 100 are compressed by the inside wall of channel 410. In some embodiments, this compression increases the outward force applied to the interior wall of the first channel 410, and likewise increases the inward force applied to the portion of the strap 100 in contact with the inside wall of the first channel 410. The increased force increases the friction between strap 100 and first channel 410 in accordance with the previously recited equation, Fr=N, where Fr is the resistive force of friction, is the coefficient of friction for the two surfaces, N is the normal or perpendicular force between the two objects. Because friction increases with force, embodiments that employ compressible materials in forming strap 100 realize further positional security and stability of strap 100 within channel 410. In some embodiments the inside wall 411 of the first channel 410 includes a ridge 412 protruding into the aperture that forms first channel 410. Strap 100 is situated through first channel 410 when the cord clip 1000 is assembled, and ridge 412 within first channel 410 ensures there is sufficient compressive force applied to strap 100 to hold strap 100 in place. In some embodiments the dimensions of the channel 410 relative to the outer profile dimension of the notched portion of the strap 100 are such that ridge 412 is unnecessary. In other embodiments, the dimensions of the strap 100 otherwise fit too loosely within the channel 410, and the added functionality of the ridge 410 becomes critical to inhibiting movement. In particular, the increased force on strap 100 created by ridge 412 increases the friction between the surface of the strap 100 that is in contact with the interior wall 411 of channel 410. The increased friction results minimizes movement of the strap 100 within the first channel 410 and enables the optimized cord clip assembly to maintain its functionality.

(32) As illustrated in FIG. 4B, second channel 450 runs along a distal edge of the coupler 400 in the longitudinal direction substantially orthogonal to the direction traversed by the first channel 410. As depicted, second channel 450 is partially open and configured to receive an audio cord in a snap-fit manner. In particular, second channel 450 has an inside diameter, D.sub.450, that substantially matches the outside diameter of an audio cord. However the dimension C.sub.O of the partial opening along the length of second channel 450 is, in some embodiments, less than the outside diameter of an audio cord. With sufficient force, an audio cord may be pressed into second channel 450 such that the audio cord is held snug in place by the interior wall of second channel 450. That is, when a user attempts to press an audio cord into channel 450 via the partial opening defined by dimension C.sub.O in FIG. 4B, one or more of (i) the cord material, or (ii) the material forming the channel 450, may temporarily flex or compress such that the audio cord may settle within channel 450 resulting in a snug fit. Similarly, when a user attempts to remove an audio cord from channel 450, a sufficient amount of force will incur the same or similar flexure and compression. Accordingly, an audio cord may be releasably coupled to cord clip 1000 via channel 450 of dual-channel coupler 400. The snap-fit type design for the cord clip of the presently disclosed technology minimizes slippage and enhances the security and stability of the audio cord's position.

(33) FIG. 5A is a side view of a cord clip in a closed configuration in accordance with one embodiment of the disclosed technology. The closed configuration embodiment depicted in FIG. 5A illustrates how cord clip 1000 functions to minimize rotation and other cord movements. The closed configuration is held in place by the attractive forces between the ferromagnetic units disposed in pocket 210 and pocket 220 when brought close together. As depicted, the closed configuration of optimized cord clip 1000 defines a new aperture 234. The formation of aperture 234 is provided to allow the hemmed collar of a t-shirt or other hemmed portion of other apparel to be situated therein. As will be discussed in more detail with reference to FIGS. 6A-6C, the square edge of pocket 210 is designed to situate adjacent to the edge of a t-shirt hem when the cord clip is worn by a user, such that neither the cord clip nor the shirt collar can rotate relative to the other. In some embodiments, the cord clip is designed to utilize the structure provided by a tee-shirt (or other apparel) to minimize cord movement while securing the cord to the user's apparel.

(34) FIG. 5B is a side view of a cord clip in another closed configuration in accordance with one embodiment of the disclosed technology. FIG. 5B is similar to 5A, but illustrates an additional configuration, where the second channel 450 of cord clip 1000 is facing the inside of the cord clip when in the closed position. In some instances a user may wish to employ such a configuration to further secure an audio cord. In such embodiments, the total length L.sub.T of strap 100 is slightly longer, ranging from 70-90 mm in length, to ensure that the dual-channel coupler 400 does not obstruct aperture 234 in a manner that precludes the interlocking feature to occur as between the edges of the pocket 210 and hem.

(35) FIG. 6A is a side view of a tee-shirt with a cord clip attached thereto in accordance with the technology disclosed herein. As illustrated, optimized cord clip 1000 may clasp around the edge of a collar 61 of tee shirt 60. In exemplary embodiments, hem 61 of shirt 60 fits within aperture 234 such that the top edge 216 of pocket 210 or 220 aligns with the bottom edge of a hem 61. In this arrangement, hem 61 provides structure which cord clip 1000 can leverage in order to resist rotational and other forces. In other embodiments, edge of hem 61 may not necessarily align (e.g. in parallel) with an edge of pocket 210 or 220, but the apparel may be gathered into aperture 234 in a manner that provides similar such structure for cord clip to leverage when resisting rotational and other forces. FIG. 6B is a schematic diagram illustrating a magnified view of the cord clip shown in FIG. 6A, symbolically depicting the location of pocket 210 and hem 61 of shirt 60 in accordance with an embodiment of the technology disclosed herein. As illustrated, a bottom edge of hem 61 substantially aligns with top edge of pocket 210. Because neither edge is rounded, rotational movement of the shirt 60, hem 61 and cord clip 1000 with respect to one another is minimized.

(36) FIG. 6C is a magnified cross-sectional view of the cord clip shown in FIGS. 6A and 6B, here depicting several of the layers discussed earlier in connection with FIGS. 1A-3B. First layer 200 and second layer 300 are coupled together; pockets 210 and 220 are situated on the same side of first layer 200 such that they may come in contact with one another when the attractive force between the ferromagnetic units is engaged. When worn by a user, cord clip 1000 clasps a portion of a user's apparel (e.g. tee-shirt 60) such that a portion of the collar or hem of the user's apparel is disposed within an aperture 234 defined in part by the interior portion of first layer 200 when the cord clip is in a closed position. The outside portion of pocket 210 and pocket 220 come in direct contact with user's apparel, and exert compressive force on the material that further inhibits rotational and other movements.

(37) While various embodiments of the disclosed technology have been described above, it should be understood that they have been presented by way of example only, and not of limitation. Likewise, the various diagrams may depict an example architectural or other configuration for the disclosed technology, which is done to aid in understanding the features and functionality that can be included in the disclosed technology.
