Description

TECHNICAL FIELD

The present disclosure relates to listening devices such as headphones that are designed to be worn on or around the head over a user's ears.

BACKGROUND

Headphones are designed to allow a single user to listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the surrounding environment for anyone to hear. Headphones often include electroacoustic transducers which convert electrical signal to a corresponding sound in the user's ear. Headphones may include circular or ellipsoid ear pads that encompass or rest against the ears. The ear pads are typically connected to one another by a semi-rigid flexible spring-steel band e.g., headband, adapted to be placed on a user's head and a wire that electrically connects two or more speakers enclosed by the ear pads. The headband is typically curved and provides sufficient force to the ear pads to hold the headphones in place. The headphones may be adjustable so a user may change the position of the ear pads for comfort. The speakers, spring-steel band, wire, and other internal components are often enclosed plastic cover pieces that are fastened together by screws, glue, or a snap-fitting arrangement. The cover may include aesthetically pleasing ornamental designs.

DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

Headphones generally include multiple plastic pieces that make up an enclosure to cover and protect the electrical and structural components of a pair of headphones. Headphones may include circular or ellipsoid ear pads that encompass or rest against the ears. The ear pads are typically connected to one another by semi-rigid flexible spring-steel band, e.g., headband adapted to be placed on a user's head and wire electrically connecting at least two speakers each disposed adjacent to the ear pads. The use of plastic components often requires a certain thickness to maintain some structure to protect the spring-steel band, wires, and speakers. To fold the headphones, multiple plastic components must be separated to provide sufficient space or a hinge to bend the headphones into a collapsed position. Because plastic is used as the enclosure separate soft ear pads must be provided.

The disclosure recognizes the above issues and provides an approach to at least partially address it. The present disclosure relates to a seamless knit headphone enclosure and a method of making the same. The enclosure is may comprised of a single piece of fabric having a tubular construction. The headphone enclosure may provide sufficient rigidity in certain locations to maintain and hold the internal components of the headphone assembly together. Other locations are flexible to allow the headphones to be folded into a compact shape. The varying rigidity and flexibility of the enclosure is accomplished by utilizing different stitch constructions offering corresponding elasticity. The headphone enclosure has a one-piece design thereby simplifying the assembly of the headphones. As an alternate embodiment, the headphone enclosure may be used as an accessory and act as an aesthetically pleasing cover for a conventional headphone assembly.

A seamless knit structure is often produced by what is referred to as a complete garment knitting process or three-dimensional (3D) knitting. As opposed to conventional knitting, that requires shaped pieces to be sewn together, 3D knitting machines utilize computerized instructions that direct movement of several needs to construct and connect several tubular knitted forms to create a complete garment in a single step. 3D knitting decreases wasted materials and eliminates several steps associated with conventional sewing.

3D knitting may be accomplished by various techniques, including but not limited to flat knitting, warp knitting, weft knitting and circular knitting. In one embodiment, the seamless headphone enclosure is may be produced by flat bed weft knitting. Flat bed weft knitting is a method that creates a knitted fabric by moving a number of feeders or vessels that carry the thread across a needle bed. As the needles within the needle bed move up and down to engage the thread, a loop is created. As multiple loops are created, the knitted structure is developed.

The amount of material generated is measured by wales per inch (WPI). The amount of WPI is dependent on the number of needles required to create an inch width of fabric. As one example, if a piece of fabric has a 50 WPI then 50 needles are required to create one inch. Another unit of measure related to knitted structure is course per inch (CPI). CPI refers to how many knitting rows required to create one inch of a knitted part. As one example, if a piece of fabric has a 100 CPI, then 100 knitting rows are required to complete one inch of knitting.

In one embodiment, flat bed differs from warp knitting, circular knitting, or weaving. Flat bed knitting facilitates the creation of more versatile, complex, and unique products with various materials in isolated areas. Conventional flat bed weft knitting typically has only two needle beds. The process used to create the headphone enclosure may have four needle beds. A variety of yarns may be utilized to create the headphone enclosure of one or more embodiments. In one embodiment, one feeder provides a double covered elastic yarn that has an elastane core covered in nylon. The other yarn may have a composition that is 83% nylon and 17% spandex by weight. In other embodiments the composition may include one of or a range of the following percentage of nylon, with the balance being spandex: 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, by weight. In other embodiments the composition yarn may include a percentage of steel or carbon fiber by weight with the balance being either nylon or spandex.

In the following discussion of the figures, a polar coordinate system is utilized. A longitudinal axis extends along the headband between the earpieces of the headphone enclosure. A transverse axis extends orthogonal to the longitudinal axis.

The headphone enclosure may include at least seven regions, each comprising a stitch construction that is unique to each region. Each stitch construction provides a unique elasticity. Elasticity may refer to the ability of the region to resist distortion or deforming and its ability to retain or return to its original size and shape. Elasticity may be measured along the longitudinal or the transverse axis, or both. Mechanical strain is integrally related to elasticity. While elasticity refers to the property of solid material to return to its original shape and size after the force deforming it has been removed, strain refers to a change in some spatial dimension, e.g., length, angle or volume, compared to its original value.

Mechanical properties of a weft knitted structure may vary depending on the type of stitch or stitch construction utilized. The strain of a knitted structure refers to the percentage change in length in response to a constant force. A knit structure having a “low strain rate” or “low elasticity” may have a range between 1% and 11%. A knit structure having a “medium strain rate” or “medium elasticity” structure may have a range between 11% and 14%. A knit structure having a “high strain rate” or “high elasticity” may have a range between 14 and 20%.

FIGS. 1 through 3 illustrate the location of each region according to at least one embodiment of this disclosure. FIGS. 4 through 11 illustrate the stitch construction used in each region. With the exception of the sixth region 26 the other regions are duplicated on either side of the sixth region 26. Between each region, a transition is provided. Because each region has a unique stitch construction, a transition region is required to connect the regions.

Referring to FIG. 1, a perspective view of a headphone unit that includes the seamless knit headphone enclosure 10 worn by a user is illustrated. The headphone enclosure 10 includes a pair of earpieces 3436 (only one is illustrated) connected by a headband 30.

Referring to FIGS. 2-3, top views of an external side 10a and an inner side 10b of the headphone enclosure are illustrated. The external side 10a may be the side opposite of the inner side 10b that is adjacent to a user's head and ears during use. As mentioned above, the headphone enclosure 10 is comprised of seven regions according to one embodiment. Each region is comprised of a unique stitch construction or thread construction that provide aesthetic and structural characteristics. A first region 16 has a black and white lined pattern extending substantially parallel to the longitudinal axis. The first region 16 may be comprised of an alternate tuck thread structure. The alternate tuck thread structure provides a medium elasticity along the longitudinal and transverse axes.

A pair of second regions 24 make up a portion of the headband 30 that extend to the earpieces 3436. The two second regions 24 are each comprised of an alternate miss pattern that only knits on every fourth needle. This thread structure provides a low elasticity as along the transverse axis and a medium elasticity along the longitudinal axis.

A third region 18 is disposed between the first region 16 and a portion of the outer periphery of each earpiece that extends along the direction of the longitudinal axis. Like the first regions 16, the third region 18 is comprised of an alternate tuck thread structure. As mentioned above, the alternate tuck thread structure provides a medium elasticity along the longitudinal and transverse axes. Despite having the same thread structure as the first region 16, the aesthetic pattern of the third region 18 differs from the first region in that it is a series of cross-hatched lines.

Each earpiece includes an aperture 38 that is sized to accommodate the insertion of a headphone assembly (not pictured). A fourth region 20 extends around the periphery of the aperture 38. The fourth region 20 is comprised of a links links stitch construction. The links links stitch construction provides maximum elasticity along the longitudinal and transverse axes. The maximum elasticity of the stitch construction facilitates the insertion of the headphones. Peripheral stitching 23 surrounding the aperture 38 is comprised of a thread structure made from C-Knitting. The peripheral stitching 23 will be explained in greater detail below.

A fifth region 22 is disposed between the first region and the fourth region. The fifth region 22 is comprised of a one by one rib stitch construction. Similar to the fourth region 20, the fifth region 22 provides maximum elasticity along the longitudinal and transverse axis. Again, the maximum elasticity of the stitch construction facilitates the insertion of the head phones.

The headband 30 may include a sixth region 26 and two second regions 24 disposed on either side of the sixth region 26. The sixth region 26 may have a black and white dotted pattern and the two second regions 24 have a black and white striped pattern that extend parallel to the longitudinal axis. The sixth region is comprised of an alternate tuck thread structure. The alternate tuck thread structure provides a medium elasticity along the longitudinal and transverse axes.

A seventh region 12 is disposed between the fifth region 22 and a portion of the outer periphery that is transverse to the longitudinal axis. The seventh region 12 has an aesthetic pattern of a series of alternating black and white lines that are substantially aligned parallel with the longitudinal axis. The seventh region is comprised of an alternate miss stitch construction. The alternate miss stitch construction provides a low elasticity along the transverse axis.

As mentioned above, a number of transitions are provided between the regions. A first transition 40 is provided between the second region 24 and the sixth region 26. The first transition 40 is used to create a half-gauge twill pattern that is consistent with the width and the drop required to fit the enclosure 10 on the headphone band. A second transition 42 is provided between the second region 24 and the fifth region 22. The second transition 42 facilitates the change between a full gauge construction to a half gauge construction. A third transition, is used throughout the seventh region 12. A fourth transition 44, forms the start, indicated by “s,” and the end, indicated by “e” of the headphone enclosure 10. The fourth transition 44 as further shown in FIG. 2A, facilitates seamless movement of the needles inward to decrease the width of the knitting without creating any holes. A fifth transition 46, is provided between the single jersey construction of the first region 16 and the one by one rib construction of the fifth region 22.

Referring FIG. 2A, the seventh region 12 extends between a portion of the outer periphery of the earpieces 34, 36 to the first region 16. The first region extends circumferentially around the fifth region 22. The third region 18 extends between a portion of the outer periphery of the earpieces and the first region 16. A second region 24 within the headband 30 is shown in FIG. 3D. The fourth region 20 has a links links stitch construction. Region 6B 28 is the transition between the second region 24 of the headband 30 and the earpieces 3436.

FIG. 4 through FIG. 11 illustrate various stitch constructions created by the knitting process for each region. The lines represent needles on the needle bed of the 3D knitting machine. Four separate needle beds may be employed; a front upper bed 52, front lower bed 54, back lower bed 56, and back upper bed 58. The illustrations represent a repeating pattern of the four needle beds and the shape and pattern of the individual yarns. Each individual yarn is shown separately, i.e., not interwoven.
