The present technology relates generally to the field of personal audio devices, and more particularly to securing cords used with such devices.
The use of personal audio and media devices has become pervasive in recent years. Today's audio and media devices are small enough that they can now be used in a much wider range of activities than earlier devices. Though many of these devices come equipped with internal speakers for audio playback, nearly all such devices are also equipped with an auxiliary or other port for enabling a user to connect a pair of headphones or earphones (used interchangeably throughout this disclosure) to the device. Headphones and earphone devices have further enabled users to listen to audio and other media (e.g. music, voice, etc.) while engaging in other activities. For example, if a user wants to listen to music while going for a run, they can simply put on a pair of headphones, connect the headphones to a small multi-media device (e.g. a smartphone, MP3 player, etc.) and enjoy their music while they exercise.
Most earphone and headphone devices come equipped with a cord (containing wiring) used to electronically connect the speakers in the headphones to the signal producing functionality of the multimedia device being used. When user's wish to use their multimedia devices while performing a physical activity, they often place the multimedia device in a pocket of their clothing or secure the device using an armband, wristband, etc. Thus, the cord of the headphones runs from the multimedia device clear up to the user's head where the earphones are worn. As a user performs a physical activity, however, the cord can flail about in various directions, become tangled with or caught on other objects, and inevitably tug on the earphones themselves. This results in annoyance and discomfort for the user and often requires the user to make repeated adjustments with their device or to resituate the cord. Additionally, in some cases such movement of the audio cord can cause vibrations that translate into audio interference that disturbs quality of sound the user experiences.
In more advanced earphones, the earphone housings may be configured with various sensors and circuitry that provide additional functionality (e.g. heartrate detection, motion detection, etc.). The functionality of these devices requires secure and stable placement of the earphone in a user's ear. Thus, if the cord of these devices is jostled or moved about too vigorously during an activity, it can displace an earphone from its proper position and compromise the accuracy of the sensors embedded within. This can defeat the entire purpose for using the earphones. For example, a user may wish to use earphones with biometric sensors while jogging so that they can monitor their heartrate during an exercise session. If the cord is not properly secured while the user is jogging, the cord may repeatedly tug on earphones and undermine the ability of the sensors in the earphones to obtain an accurate reading. Accordingly, there is an even greater need for cord stability when using these advanced devices. Even where wireless earphones are used (i.e. such that the cord does not run all the way to the multimedia device), however, the cord nevertheless runs between the two earphones themselves (generally resting on the back portion of a user's neck). Movements of the cord in these devices, albeit less sever in many instances, can still give rise to the above mentioned drawbacks.
In view of these drawbacks, many attempts have been made to develop a device that can secure an audio cord to avoid tangling and other interference. However, presently available cord securing devices continue to suffer from cord slippage, as well as rotational movement of the actual device itself around the point of contact (and thereby also resulting in cord movement). Indeed, while various devices have been developed, none have been able to secure audio cords in an adequate manner; especially for advanced earphones that incorporate biometric sensors. Accordingly, a need exists for a cord securing device that employs a technical and scientific approach to solving the aforementioned problems.
In view of the above drawbacks, the present disclosure is directed toward an optimized cord clip configured to leverage the structural and mechanical features of a user's clothing to more effectively secure an audio cord. An embodiment of the present disclosure includes a coupling device that serves to securely connect a flexible strap to an audio cord, the strap itself also being securely clasped onto another item (e.g. an item of clothing the user is wearing). The coupling device (also referred to herein as the dual-channel coupling device) prevents unnecessary cord slip by employing a snap-fitting feature that securely manages the audio cord. At the same time, the clasping mechanism provided by the unique configuration of the strap, pockets, and ferromagnetic metals enables the cord clip to resist rotational forces exerted on the cord clip when a user is engaged in a physical activity imposing such forces. Exemplary embodiments of the present disclosure include a strap made of one or more flexible materials (spandex, suede, silicon, rubber, etc.) that can fold in half to clasp onto another item. The clasping force is generated by attractive forces between two or more ferromagnetic materials. The ferromagnetic materials are disposed in pockets within the strap, the pockets typically being situated near opposite ends of the strap such that when the strap folds in half, the position of the ferromagnetic materials substantially align. The point about which the strap folds is disposed within a channel of the coupling device, which in some embodiments is situated near the middle of the strap. The coupling device is in some embodiments, a rigid material, but in other embodiments may be substantially non-rigid. The coupling device is configured with at least two channels or conduits. As mentioned above, a mid-portion of the strap is situated within one of these channels, and the other channel is configured with an opening fitted to receive an audio cord in a snap-fit manner.
In particular embodiments, an optimized cord clip of the present disclosure includes two ferromagnetic units contained in pockets located near opposing ends of a flexible strap. In embodiments of the present technology, the pockets are shaped 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 the 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 overall movement of the audio cord itself. The optimized design of the cord clip minimizes rotation of the cord clip about a collar and further minimizes other movements. 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.).
The technology disclosed herein, in accordance with one or more various embodiments, is described in detail with reference to the following figures. The drawings are provided for purposes of illustration only and merely depict typical or example embodiments of the disclosed technology. These drawings are provided to facilitate the reader's understanding of the disclosed technology and shall not be considered limiting of the breadth, scope, or applicability thereof. It should be noted that for clarity and ease of illustration these drawings are not necessarily made to scale.
The figures are not intended to be exhaustive or to limit the disclosure to the precise form disclosed. The figures are not drawn to scale. It should be understood that the disclosed technology can be practiced with modification and alteration, and that the disclosed technology may be limited only by the claims and the equivalents thereof.
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.
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.).
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.
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.

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, T100, 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 W210 of first layer 200 and W310 and second layer 300 fit (either in a relaxed or compressed state) within first channel 410 of dual-channel coupler 400. Additionally, thickness dimension T100 of strap 100 fits (either in a relaxed or compressed state) within first channel 410 of dual-channel coupler 400.
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=μN, where Fr is the resistive force of friction, μ 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.
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, D450, that substantially matches the diameter of an audio cord. The second channel 450 is also configured with a partially open side having a dimension, CO, 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.
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
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=μN, where Fr is the resistive force of friction, μ 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.
