DETAILED DESCRIPTION
According to various embodiments, the present invention is directed to a headband assembly that can be used with personal speakers and worn, for example, on the head of a human user. Referring primarily to FIGS. 1-3, a headband assembly 22 can include a spring band 30, a sleeve or attachment portion 40a, and an extension arm 60a. As described herein, the sleeve 40a can be attached to an end of the spring band 30, and the extension arm 60a can be moveably secured to a sleeve 40a. In various embodiments, the headband assembly 22 can include a single spring band 30, two sleeves 40a, 40b, and two extension arms 60a, 60b, for example. The first sleeve 40a can be attached to a first end 32 of the spring band 30 and the second sleeve 40b can be attached to a second end 34 of the spring band. Furthermore, the first extension arm 60a can be moveably secured to the first sleeve 40a and the second extension arm 60b can be moveably secured to the second sleeve 40b. A component on a first side of the headband assembly may have a corresponding or identical component on a second side of the headband assembly 22. In other words, the components of the headband assembly 22 can be modular. For example, the first sleeve 40a can be interchangeable with the second sleeve 40b and the first arm 60a can be interchangeable with the second arm 60b. Accordingly, throughout this Detailed Description, elements and/or characteristics of a component on a first side or a second side of the headband assembly 22 may be described and, unless otherwise indicated, such description is intended to apply to the corresponding or identical component on the other side of the headband assembly 22, as well.
In various embodiments, the headband assembly 22 can be positioned relative to a user's head and/or neck. For example, the headband assembly 22 can fit around the top and/or the crown of a user's head, and/or around the back and/or nape of a user's neck. A pair of personal speakers, such as earphones 100a, 100b (FIGS. 21 & 22) may be attached to the headband assembly 22. The headband assembly 22 can hold the earphones 100a, 100b relative to the user's head and/or neck, and specifically relative to the user's ears such that the earphones 100a, 100b are in, over, and/or around the user's ears, for example. The headband assembly 22 can be adapted for use with various sizes and styles of earphones 100a, 100b, for example.
Referring now to FIG. 4, the spring band 30 can be contoured or arced. Furthermore, the spring band 30 can have a spring constant such that the deformation of the spring band 30 from an initial configuration to a deformed configuration can result in a springback or restoring force. In various embodiments, the spring band 30 can be deformed from the initial configuration to the deformed configuration when the spring band 30 is positioned relative to the user's head and/or neck. For example, the spring band 30 can be deformed to a less contoured or less arced configuration when positioned relative to the user's head and/or neck. Consequently, the spring band 30 can exert a springback force on the user's head and/or neck as the spring band 30 seeks to return or to substantially return to its initial configuration. Such a springback force can help to secure the spring band 30, and ultimately the entire headband assembly 22, in place relative to the user's head and/or neck. Furthermore, in some embodiments, the spring band can generate a springback or restoring force of approximately 1.25 lb when positioned relative to the user's head and/or neck. In at least one embodiment, the spring band 30 can generate a springback or restoring force of approximately 0.75 lb to approximately 2.0 lb when positioned relative to the user's head and/or neck.
The spring constant of the spring band 30 can at least depend on the dimensions and material thereof. In at least one embodiment, the spring band 30 can be approximately 5.3 inches by approximately 0.75 inches by approximately 0.03 inches with an initial, undeformed radius of curvature of approximately 3.3 inches. In various embodiments, the dimensions of the spring band 30, including the radius of curvature, can be selected such that the spring band 30 comfortably fits the user's head and/or neck. Additionally, the dimensions of the spring band 30 can be selected such that the spring band 30 smoothly interfaces with the other headband assembly 22 components such as the sleeve 40a, for example. In at least one embodiment, the spring band 30 can comprise stainless steel, for example. In various embodiments, the spring band 30 can comprise metallic and/or polymeric materials, for example, such as nylon and/or acrylonitrile butadiene styrene (ABS), for example.
Referring still to FIG. 4, the spring band 30 can include the first distal end 32 and the second distal end 34. As described herein, the first distal end 32 and/or the second distal end 34 of the spring band 30 can be positioned in and/or disposed through a portion of one of the sleeves 40a, 40b such that the sleeve 40a, 40b is attached to the spring band 30 at or near the respective distal end 32, 34 thereof. The spring band 30 can include a pronged portion 36 extending from a distal end 32, 34 along a portion of the spring band 36. Still referring to FIG. 4, the spring band 30 can include the pronged portion 36 extending from the first distal end 32 and the pronged portion 36 extending from the second distal end 34. The pronged portion 36 can be defined by a slot 37 that extends from the respective distal end 32, 34 through a portion of the spring band 30, such as 1.0 inch or 20% of the length of the spring band 30, for example. The pronged portion 36 can taper as the pronged portion 36 approaches the respective distal end 32, 34, for example. In various embodiments, the pronged portion 36 can be deformable. For example, the prongs of the pronged portion 36 can move towards each other and the width of the slot can be reduced to compress or narrow the width of the pronged portion 36 of the spring band 30. When the pronged portion 36 is deformed, the spring band 30 can exert a springback or restoring force as it seeks to return or substantially return to its initial configuration. As described herein, such a springback force generated by the pronged portion 36 can help to secure the spring band 30 to the sleeve 40a, 40b positioned relative thereto. In various embodiments, the spring band 30 can include additional slots and/or prongs, for example. In other embodiments, the spring band 30 may not include a slot and/or prongs, but may have other features or geometries that provide springback when a portion of the spring band 30 is deformed or compressed.
Still referring primarily to FIG. 4, the spring band 30 can include tabs 38a, 38b, 39a, 39b designed to help secure the spring band 30 to the first sleeve 40a and/or the second sleeve 40b. In various embodiments, the tabs 38a, 38b, 39a, 39b can be laterally opposed tabs. For example, a tab 38a, 38b, 39a, 39b can extend from a first lateral side of the spring band 30 in a first direction and a corresponding tab 38a, 38b, 39a, 39b can extend from an opposite lateral side of the spring band 30 in a second direction. In some embodiments, the second direction can be substantially opposite to the first direction. Referring still to FIG. 4, the first side of the spring band 30 can include two pairs of opposing tabs 38a, 39a, for example, and the second side of the spring band 30 can include two additional pairs of opposing tabs 38b, 39b, for example. A first pair of opposing tabs 38a can be positioned near or at the first distal end 32 and/or a second pair of opposing tabs 39a can be positioned farther from first distal end 32 such as, for example, past the slot of the pronged portion 36. Furthermore, the spring band 30 can include a third pair of opposing tabs 38b near or at the second distal end 34 and/or a fourth pair of opposing tabs 39b farther from second distal end 34 such as, for example, past the slot of the pronged portion 36. In other words, the spring band 30 can have two pairs of opposing tabs 38a, 39a near or around the first distal end 32 and two more pairs of opposing tabs 38b, 39b near or around the second distal end 34. Further, in various embodiments, the tabs 38a, 39a on the first side of the spring band 30 can form a mirror image reflection of the tabs 38b, 39b on the second side of the spring band 30. As described herein, when the sleeve 40a is positioned relative to the first end 32 of the spring band 30, the tabs 38a, 39a of the spring band 30 can engage the sleeve 40a to help secure the sleeve 40a to the spring band 30.
Referring primarily to FIGS. 5-8, the sleeve or attachment portion 40a can have a contoured or arced body that is configured for receiving a portion of the spring band 30. The contour of the sleeve 40a can be selected such that the sleeve 40a comfortably fits on and/or around a portion of the user's head and/or neck, for example. Furthermore, as described herein, the sleeve 40a can be designed to releasably attach to the spring band 30 (FIG. 4) and to adjustably hold and retain the extension arm 60a (FIGS. 7 & 12-14). The sleeve 40a can include a slot 42 for receiving a portion of the spring band 30 (FIGS. 1-4) therein. The slot 42 can extend through a portion of the sleeve 40a to an opening 50. In various embodiments, the opening 50 can include a groove or notch 51 (FIGS. 6 & 8) therein. Referring again to FIGS. 1-3, when the first end 32 of the spring band 30 is positioned relative to the sleeve 40a, the first end 32 of the spring band 30 can extend through the slot 42 such that an end portion of the spring band 30 is disposed in the sleeve 40a. Further, the groove 51 of the opening 50 can hold the first distal end 32 of the spring band 30. In other embodiments, the first end 32 of the spring band 30 may be held within the slot 42 of the sleeve 40a, for example.
In various embodiments, the spring band 30 and the sleeve 40a can form a snap-fit connection. For example, referring primarily to FIG. 2, the pronged portion 36 of the spring band 30 can be narrowed or compressed to fit through the slot 42 of the sleeve 40a. In various embodiments, the opposing tabs 38a nearest the first distal end 32 should also fit through the slot 42 when the pronged portion 36 is narrowed or compressed. When the pronged portion 36 is compressed, the pronged portion 36 can exert a springback force on the sleeve 40a in which the pronged portion 36 is retained as the pronged portion 36 seeks to return or substantially return to its undeformed configuration. Opposing tabs 38a can be positioned in the opening 50 and can engage the sleeve 40a as the pronged portion 36 seeks to return to its undeformed configuration. The springback force can cause the opposing tabs 38a that are positioned in the opening 50 to catch the sleeve 40a, which can restrict detachment of the sleeve 40a from the spring band 30. For example, the opposing tabs 38a can catch the sleeve 40a such that the pronged portion 36 cannot be withdrawn through the slot 42. Furthermore, the opposing tabs 39a that are positioned outside of the sleeve 40a (FIGS. 1 & 3) can prevent over-insertion of the spring band 30 into the sleeve 40a. For example, the opposing tabs 39a can catch the sleeve 40a if the first end 32 of the spring band 30 attempts to over-advance through the slot 42. In other words, the opposing tabs 38a, 39a can releasably lock the spring band 30 in position within the sleeve 40a and can prevent unintended retraction and/or over-insertion.
Referring again to FIGS. 1-3, the sleeve 40a can releasably attach to the spring band 30. In other words, the sleeve 40a may be selectively detached from the spring band 30. For example, the pronged portion 36 of the spring band 30 can be compressed or squeezed to move the prongs inward such that the tabs 38a disengage the sleeve 40a and permit the pronged portion 36, including the opposing tabs 38a, to be withdrawn through the sleeve 40a. For example, the pronged portion 36 positioned in the opening 50 can be manually pinched and/or manipulated to release the spring band 30 from the sleeve 40a. 
Referring again to FIGS. 5, 7-8, the sleeve 40a can include an opposing detent arrangement 44. The opposing detent arrangement 44 can include a group of one or more detent pockets 48 on a first internal side of the sleeve 40a and an opposing group of one or detent pocket 48 on a second internal side of the sleeve 40a. In various embodiments, the opposing detent arrangement 44 can include a first plurality of detent pockets 48 on a first side of the sleeve 40a and a second plurality of detent pockets 48 on the second side of the sleeve 40a, preferably equal in number to the first plurality of detent pockets. The second plurality of detent pockets 48 can be laterally positioned relative to the first plurality of detent pockets 48, for example. In various embodiments, the first and second pluralities of detent pockets 48 can each be arranged in a row. For example, the sleeve 40a can have a pair of laterally opposed channels 46a, 46b (FIG. 5) on opposing internal side of the sleeve 40a. The first channel 46a on the first internal side of the sleeve 40a can include the first plurality of detent pockets 48 arranged in a row, for example, and the second channel 46b on the second internal side of the sleeve 40a can include the second plurality of detent pockets 48 arranged in a row, for example. In various embodiments, the first channel 46a and the first plurality of detent pockets 48 can form a mirror image reflection of the second channel 46b and the second plurality of detent pockets 48. In other embodiments, the channels 46a, 46b and pluralities of detent pockets 48 on each side of the sleeve 40a may be asymmetrical.
Referring again to FIGS. 5-8, the sleeve 40a can include a wing 54 that extends from the body of the sleeve 40a. The wing 54 can be structured for attachment of the cap 80 (FIG. 8). In various embodiments, the wing 54 can have a hole 56 (FIGS. 5-7) therethrough, which can receive a fastener 90 (FIGS. 9 & 11). As described herein, the fastener 90 can secure the cap 80 to the wing 54 of the sleeve 40a. Referring primarily to FIG. 6, the sleeve 40a can have a sleeve liner 98, which can be positioned relative to the sleeve 40a to enclose or encase the opposing detent arrangement 44 of the sleeve 40a. In other words, the opposing detent arrangement 44 can be on an internal surface of the sleeve 40a. When the arm 60a is positioned relative to the sleeve 40a, as described herein, the liner 98 and the sleeve 40a can at least partially surround or enclose a portion of the arm 60a. In various embodiments, the liner 98 and the sleeve 40a can surround the arm 40 such that the arm 60a is protected as it moves relative to the sleeve 40a. 
In at least one embodiment, the sleeve 40a can be approximately 2.5 inches by approximately 1.125 inches by approximately 2.25 inches with a radius of curvature of approximately 3.0 inches. In various embodiments, the dimensions of the sleeve 40a, including the radius of curvature, can be selected such that the sleeve 40a comfortably fits the user's head and/or neck. Additionally, the dimensions of the sleeve 40a can be selected such that the sleeve 40a smoothly interfaces with the other headband assembly 22 components such as the spring band 30, the arm 60a and/or the cap 80, for example. In at least one embodiment, the sleeve 40a can comprise nylon and/or acrylonitrile butadiene styrene (ABS) for example. In various embodiments, the sleeve 40a can comprise various metallic and/or polymeric materials, for example.
Referring now to FIGS. 12-14, the extension arm 60a can have a contoured or arced body. The contour of the extension arm 60a can be selected such that the extension arm 60a comfortably fits on and/or around a portion of the user's head and/or neck, for example. Further, the contour of the extension arm 60a can match or substantially match the contour of the sleeve 40a such that the extension arm 60a can move smoothly within the sleeve 40a (FIG. 7), as described herein. Referring primarily to FIGS. 13 & 14, the extension arm 60a can include an opposing detent assembly 62. The opposing detent assembly 62 can include a pair of holes 64a, 64b, which can extend inwardly from a lateral side of the extension arm 60a. The first hole 64a can be positioned on a first lateral side of the extension arm 60, for example, and the second hole 64b can be positioned on an opposite lateral side of the extension arm 60, for example. In various embodiments, the holes 64a, 64b can be positioned near a first end 61 of the extension arm 60. Alternatively or additionally, detent holes 64a, 64b may be positioned elsewhere along the length of the extension arm 60.
Referring still to FIGS. 12-14, the opposing detent assembly 62 can include a pair of detent bearings 68a, 68b. The first detent bearing 68a can be positioned at least partially in the first hole 64a, for example, and the second detent bearing 68b can be positioned at least partially in the second hole 64b, for example. As described herein, each bearing 68a, 68b can engage the opposing detent arrangement 44 of the sleeve 40a (FIGS. 5-8). In various embodiments, the detent bearings 64a, 64b can be spring-loaded bearings. Accordingly, a first coil spring 66a can be positioned in the first hole 64a and can operably exert an outward springback force on the first detent bearing 68a positioned therein. Similarly, a second coil spring 66b can be positioned in the second hole 64b and can operably exert an outward springback force on the second detent bearing 68b positioned therein.
Referring now primarily to FIG. 7, the extension arm 60a can be adjustably secured to the sleeve 40a. The first bearing 68a can adjustably engage one pocket 48 of the first plurality of detent pockets in the first channel 46a (FIG. 5) of the detent arrangement 44 and the second bearing 68b can adjustably engage one pocket 48 of the second plurality of detent pockets 48 in the second channel 46b (FIG. 5) of the detent arrangement 44. In various embodiments, the detent pockets 48 and the bearings 68a, 68b can be symmetrical. When the first bearing 68a engages one pocket 48 of the first plurality of pockets and the second bearing 68b engages one pocket 48 of the second plurality of pockets, the first and second bearings 68a, 68b can adjustably secure the arm 60a to the sleeve 40a. The opposing detent assembly 62 of the arm 60a and the opposing detent arrangement 44 of the sleeve 40 can provide for smooth and balanced adjustment of the arm 60a relative to the sleeve 40a. For example, as the first detent bearing 68a interfaces with the first plurality of detent pockets 48 in the first channel 46a and the second detent bearing 68b interfaces with the second plurality of detent pockets 48a in the second channel 46b, the springback forces generated by the opposing detent bearings 68a, 68b can be balanced. In other words, the springback force generated by the first detent bearing 68a on a first side of the sleeve 40a can match or substantially match the springback force generated by the second detent bearing 68b on an opposing side of the sleeve. Further, the forces can be balanced or substantially balanced as the detent bearings 68a, 68b of the arm 60a transition between detent pockets 48 of the sleeve 40a. The balance of forces can provide for a smoother adjustment or transition as the arm 60a extends and/or retracts relative to the sleeve 40a. In various embodiments, the opposing detent assembly 62 of the extension arm 60a can include a second pair of holes and a second pair of detent bearings. Similar to detent bearings 68a, 68b, the second pair of detent bearings may engage pockets 48 in the opposing detent arrangement 44 to adjustably secure the extension arm 60a to the sleeve 40a.

In various embodiments, the magnetic pivot arrangement 70 can include a magnetic element 78a in the extension arm 60a, and a magnetic element 122a in the yoke 108 of the attached earphone 100a. For example, the magnetic element 78a in the first extension arm 60a can pivot into and/or out of alignment with the magnetic element 122a in the yoke 108 as the first extension arm 60a pivots relative to the first earphone 100a. In various embodiments, the magnetic pivot arrangement 70 can include a pair of magnetic pivot elements 78a, 78b in the extension arm 60a, and a pair of magnetic pivot elements 78a, 78b in the yoke. In certain embodiments, the magnetic pivot arrangement 70 can include additional magnetic elements. As described herein, the magnetic elements 78a, 78b, 122a, 122b can seek to maintain alignment such that the magnetic elements 78a, 78b, 122a, 122b exert a force on the extension arm 60a and/or the yoke 108 that pivots the extension arm 60a relative to the yoke, for example.
Referring to FIG. 23, the second end 63 of the extension arm 60a can include the first pair of magnetic elements 78a, 78b of the magnetic pivot arrangement 70. Furthermore, the first extension arm 60a can include a bearing surface 73, and a first pair or recesses 79a, 79b extending from the bearing surface 73 into the body of the extension arm 60a. In various embodiments, each magnetic element 78a, 78b can be embedded in a corresponding recess 79a, 79b in the extension arm 60a. For example, the magnetic element 78a can be at least slightly recessed in the recess 79a of the extension arm 60a, such that no portion of the magnetic element 78a projects beyond the bearing surface 73. Further, the magnetic element 78b can be at least slightly recessed in the recess 79b of the extension arm 60a, such that no portion of the magnetic element 78a projects beyond the bearing surface 73, for example. Referring still to FIG. 23, the extension arm 60a can include a groove 76 that extends from the bearing surface 73 into the body of the first extension arm 60a. The groove 76 can form a curved profile in the second end 63 of the first extension arm 60a, for example. In other words, the groove 76 can define a contour, which can have a radius of curvature. As described herein, the groove 76 can be configured to moveably receive a protrusion 112 (FIG. 25) that extends from the yoke 108 (FIG. 24) as the extension arm 60a pivots relative to the yoke 108 of the first earphone 100a (FIG. 21).
Referring to FIG. 24, the attachment portion 102 of the yoke 108 can include the second pair of magnetic elements 122a, 122b. Furthermore, the attachment portion 102 can include a second pair of recesses 118a, 118b that can extend from a mating surface 117 of the yoke 108 into the body of the yoke 108. In various embodiments, each magnetic element 122a, 122b can be embedded in a corresponding recess 118a, 118b in the attachment portion 102 of the yoke 108. For example, the magnetic element 122a can be at least slightly recessed in the recess 118a of the yoke 108, such that no portion of the magnetic element 122a projects beyond the mating surface 117. Further, the magnetic element 122b can be at least slightly recessed in the recess 122b of the yoke 108, such that no portion of the magnetic element 122a projects beyond the mating surface 117, for example. Referring still to FIG. 24, the attachment portion 102 of the yoke 108 can include an aperture 116 that extends through the yoke 108. The aperture 116 can be configured to receive the attachment element 74 (FIG. 23) of the first extension arm 60a (FIG. 23) when the first extension arm 60a is positioned relative to the yoke 108, for example.
Referring now to FIGS. 25 and 26, the magnetic pivot arrangement 70 can include a pivot plate 110, which can include the protrusion 112. In various embodiments, the protrusion 112 can form a curved profile that can match or substantially match the profile of the groove 76 (FIG. 23). In other words, the protrusion 112 can define a contour, which can have a radius of curvature that matches the radius of curvature of the groove 76 contour. For example, at least a portion of the groove 76 can have a radius of curvature of approximately 0.15 inches to approximately 0.25 inches, and at least a portion of the protrusion 112 can have a radius of curvature of approximately 0.2 inches. Furthermore, the protrusion 112 can have a width that is at least slightly smaller than the width of the groove 76 such that the protrusion 112 or at least a portion thereof can fit within the groove 76. For example, the width of the groove 76 can be approximately 0.95 inches to approximately 0.105 inches, and the width of the protrusion 112 can be approximately 0.09 inches to approximately 0.094 inches. In various embodiments, the difference between the width of the protrusion 112 and the width of the groove 76 can approximately 0.001 inches to approximately 0.015 inches. In at least one embodiment, the groove 76 can guide the protrusion 112 as the protrusion 112 moves therein. For example, the protrusion 112 can slide along at least a length of the groove 76 when the pivot plate 110 is positioned relative to the first extension arm 60a. In various embodiments, the length of the protrusion can be approximately 20% to approximately 30% the length of the groove 76, for example. Referring still to the FIG. 25, the pivot plate 110 can include an aperture 114 therethrough. In various embodiments, the aperture 114 can be configured to receive the attachment element 74 (FIG. 23) of the first extension arm 60a (FIG. 23) when the pivot plate 110 is positioned relative to the second extension arm 60a, for example as illustrated in FIG. 27. As described herein, the attachment element 74 can pivot in the aperture 114 of the pivot plate 110 as the extension arm 60a pivots relative to the yoke 108 of the first earphone 100a. 
Referring to FIGS. 24-26, the pivot plate 110 can be secured to the attachment section 102 of the yoke 108. In various embodiments, the yoke 108 can include a mating surface 117, and a rim 115, which can extend from the mating surface 117. The rim 115 can surround or partially surround the mating surface 117 of the attachment section 102, for example. In various embodiments, the pivot plate 110 can be positioned relative to the attachment section 102 of the yoke 108, such that the pivot plate 110 nests in the attachment section 102. For example, the pivot plate 110 can be positioned flush with the mating surface 117, and the rim 115 can extend at least partially around the perimeter of the pivot plate 110, for example. In various embodiments, the rim 115 can help to retain the pivot plate 110 relative to the yoke 108. For example, the rim 115 can surround or partially surround the pivot plate 110 to prevent lateral movement of the pivot plate 110 relative to the yoke 108. In certain embodiments, at least a portion of the pivot plate 110 can be substantially flush with the rim 115 of the yoke 108, and the protrusion 112 can extend beyond the rim 115 of the yoke 108, for example. The pivot plate 110 can be non-pivotally secured to the attachment section 102 of the yoke 108 such that the projection 112 remains fixed relative to the yoke 108 as the first extension arm 60a pivots relative to yoke 108 and the first earpiece 100a. Referring again to FIG. 25, when the pivot plate 110 is secured to the yoke 108, the pivot plate 110 can enclose and/or retain the magnetic elements 122a, 122b in the recessions 118a, 118b of the attachment section 102. For example, the pivot plate 110 can cover the magnetic elements 122a, 122b positioned in the yoke 108. In various embodiments, the pivot plate 110 can be positioned between the magnetic elements 78a, 78b positioned in the extension arm 60a and the magnetic elements 122a, 122b positioned in the yoke 108. For example, the pivot plate 110 can extend between the pairs of magnetic elements 78a, 78b, 122a, 122b. 
Referring now to FIGS. 27-29, the retaining ring 105 can secure the yoke 108 to the extension arm 60a. In various embodiments, the bearing surface 74 (FIG. 23) of the extension arm 60a can be positioned relative to the bearing surface 119 (FIGS. 25 and 26) of the pivot plate and the yoke 108. For example, the bearing surface 119 of the pivot plate can be adjacent to, flush with and/or abutting the bearing surface 74 of the extension 60a. The bearing surfaces 74, 119 can be configured to pivot relative to each other, for example. In at least one embodiment, the attachment element 74 of the first extension arm 60a can extend through the aperture 114 in the pivot plate 110 and/or through the aperture 116 in the attachment section 102 of the yoke 108. In various embodiments, the retaining ring 105 can grip the attachment element 74 between a distal shoulder of the attachment element 74 and the yoke 108. The retaining ring 105 can hold the attachment element 74 within the apertures 114, 116 to secure the first extension arm 60a relative to the yoke 108, for example. In various embodiments, a shouldered portion of the attachment element and/or a washer 104 can be positioned between the retaining ring 105 and the yoke 108.
Referring still to FIGS. 27-29, when the attachment element 74 engages the yoke 108 to secure the first extension arm 60a to the yoke 108, the pivot plate 110 can be positioned and held therebetween. In other words, the pivot plate 110 can be sandwiched between the first extension arm 60a and the yoke 108, for example. In certain embodiments, the attachment element 74 and the retaining ring 105 can secure the pivot plate 110 between the yoke 108 and the first extension arm 60a. Additionally or alternatively, the pivot plate 110 can be integrally formed with the yoke 108. In various embodiments, the pivot plate 110 can be fixedly secured to the yoke 108, and the protrusion 112 can extend into the groove 76 in the extension arm 60a. Further, in at least one embodiment, the attachment element 74 of the first extension arm 60a can pivot in the apertures 114, 116 (FIGS. 24 and 25) of the yoke 108 as the first extension arm 60a pivots relative to the yoke 108. As the attachment element 74 pivots in the apertures 114, 116, the protrusion 112 extending from the pivot plate 110 can slide in the groove 76 of the extension arm 60a. 
Referring primarily to FIG. 29, the groove 74 can include rotational stops 77a, 77b. In various embodiments, the attachment element 74 can pivot in a first direction relative to the yoke 108 until the protrusion 112 in the groove 76 abuts the first rotational stop 77a, and the attachment element 74 can pivot in a second, opposite direction relative to the yoke 108 until the protrusion 112 in the groove 76 abuts the second rotational stop 77b. In other words, the rotational stops 77a, 77b can limit the range of rotation of the first extension arm 60a relative to the yoke 108. In various embodiments, the rotational stops 77a, 77b of the groove 76 can permit approximately +/−90 degrees or rotation, or 180 degrees of rotation, for example. In other embodiments, the rotational stops 77a, 77b of the groove 76 can permit less than 180 degrees or more than 180 degrees, for example. In at least one embodiment, the groove 76 can comprise a complete loop or contour such that the groove 76 does not include rotational stops 77a, 77b. In certain embodiments where the groove 76 forms a complete loop, the extension arm 60a can rotate+/−360 degrees, for example.
In various embodiments, when the first extension arm 60a pivots relative to the yoke 108, the magnetic elements 78a, 78b in the extension arm 60a can pivot relative to the magnetic elements 122a, 122b in the yoke 108. The magnetic poles of the magnetic elements 78a, 78b, 122a, 122b can be arranged such that the magnetic elements 78a, 78b in the first extension arm 60a seek to substantially align with the corresponding magnetic elements 122a, 122b in the yoke 108. For example, the magnetic element 78a can seek alignment with the magnetic element 122a, and the magnetic element 78b can seek alignment with the magnetic element 122b. In various embodiments, when the yoke is pivoted away from a neutral position and into a second, pivoted position, as described herein, a magnetic attraction between the magnetic element 78b, for example, and the magnetic element 122b, for example, can pull the magnetic poles of the magnetic elements 78b, 122b toward alignment. In other words, the magnetic element 78a can exert a magnetic pulling force on magnetic element 122a, and magnetic element 78a can exert a magnetic pulling force on magnetic element 122b. Further, in various embodiments, the magnetic element 78a can resist alignment with the magnetic element 122b, and the magnetic element 78b can resist alignment with the magnetic element 122a, for example. For example, when yoke is pivoted away from a neutral position and into a second pivoted position, as described herein, the magnetic element 78a can exert a magnetic pushing force on magnetic element 122b, and magnetic element 78b can exert a magnetic pushing force on magnetic element 122b. In various embodiments, the magnetic elements 78a, 78b, 122a, 122b can be made of hard, magnetic material. The magnetic elements 78a, 78b, 122a, 122b can be permanent magnets, for example.
In various embodiments, the yoke 108 can pivot between a neutral position and pivoted positions. For example, the yoke 108 can pivot between a first neutral position, a counterclockwise second position, and clockwise second position. The first position can be between the counterclockwise second position and the clockwise second position, for example. In various embodiments, the magnetic element 78a can be aligned with the magnetic element 122a and the magnetic element 78b can be aligned with the magnetic element 122b when the yoke 108 is in the first, neutral position relative to the extension arm 60a. When the yoke 108 pivots toward the counterclockwise or clockwise second position, the magnetic element 78a can move out of alignment with magnetic element 122a and the magnetic element 78b can move out alignment with the magnetic element 122b. As the yoke 108 pivots toward the clockwise second position, magnetic element 78a can move toward alignment with the magnetic element 122b. In various embodiments, the poles of magnetic elements 78a, 122b can be arranged such that the magnetic elements 78a, 122b resist alignment. In other words, magnetic element 78a can exert a magnetic pushing force on magnetic element 122b, for example. As the yoke 108 pivots toward the counterclockwise second position, the magnetic element 78b can move toward alignment with the magnetic element 122a. In various embodiments, the poles of magnetic elements 78b, 122a can be arranged such that the magnetic elements 78b, 122a resist alignment. In other words, the magnetic element 78b can exert a magnetic pushing force on magnetic element 122a, for example. In at least one embodiment, when the yoke 108 is in the first position relative to the arm 60a, the positive pole of the magnetic element 78a can correspond to the negative pole of the magnetic element 122a, for example, and the negative pole of the magnetic element 78b can correspond to the positive pole of the magnetic element 122b, for example. The reader will understand that the magnetic pivot arrangement 70 can include additional or fewer magnetic elements, that alternative arrangements of the magnetic elements are possible, and that such arrangements are within the scope of this disclosure.
In use, a user can adjust or manipulate the assembly 20 by pivoting the yoke 108 relative to the attached extension arm 60a. For example, the magnetic elements 78a, 78b in the first extension arm 60a can be pivoted out of alignment with the magnetic elements 122a, 122b of the yoke 108 when the user positions the assembly 20 relative to the user's head and/or neck. Once misaligned, the magnetic elements 78a, 78b, 122a, 122b of the magnetic pivot arrangement 70 can seek to realign.

The reader will understand that various different and/or additional components can help to retain the collar 132 relative to the housing ring 152.
Referring primarily to FIG. 35, the pivot pin 138 of the housing pivot arrangement 130 can engage the yoke 108. In various embodiments, the yoke can have a hub 144, and a portion of the pivot pin 138 can extend into an aperture 143 (FIG. 24) in the hub 144. In various embodiments, the yoke 108 can have two hubs 144 on opposing sides of the yoke 108, for example, and a pivot pin 138 can be secured to each hub 144. The pivot pin 138 can be fastened or secured to the hub 144, for example, or can be integrally formed with the hub 144, for example. In various embodiments, the pivot pin 138 can be fixedly or non-pivotally connected to the hub 144 of the yoke 108. Referring again to FIGS. 30-34, the yoke 108 can extend at least partially around the housing ring 152, such that the hubs 144 of the yoke 108 are positioned on opposite sides of the housing ring 152, for example. Further, the pivot pins 138, which extend from the hubs 144, can each extend through an aperture 145 (FIG. 31) in the housing ring 152 and into the collar 132 that is secured therein. In various embodiments, the housing ring 152 can be pivotally connected to the yoke 108 by the housing pivot arrangement 130, which includes the collar 132 and the pivot pin 138. For example, the pivot pin 138 extending from the housing ring 152 can pivot within the aperture 145 of the housing ring 152 and in the collar 132. In certain embodiments, the housing ring 152 can be pivotally connected to the yoke 108 at opposing housing pivot arrangement 130 positioned on opposite sides of the housing ring 152. In other words, the housing ring 152 can pivot relative to the yoke 108 at opposing housing pivot arrangements 130. The collar 132 can be fixed relative to the housing ring 152, such that pivoting of the pivot pin 138 causes the yoke 108 to pivot in the collar 132 and relative to the housing ring 152. As described herein, the collar 132 can control the rotational direction and/or the range of rotation of the pivot pin 138 and the yoke 108 relative to the housing ring 152, for example.
In various embodiments, referring primarily to FIG. 36-38, the collar 132 can include an opening or space 135, an arm 134, and/or a wedge stop 136. The arm 134 can define a first side or surface of the opening 135, for example, and/or the wedge stop 136 can define a second side or surface of the opening 135, for example. In various embodiments, the wedge stop 136 surface can be angularly oriented relative to the arm 134 surface, for example. In certain embodiments, as described herein, the pivot pin 138 can be received in the opening 135 of the collar 136. For example, the pivot pin 138 can extend from the hub 144 of the yoke 108 (FIG. 35) and to between the arm 134 and the wedge stop 136 of the collar 132. The arm 134 and the wedge stop 136 can control the pivoting movement of the pivot pin 138 in the opening 135. For example, the pivot pin 138 can pivot counterclockwise from the vertical configuration (FIG. 37) until the pivot pin 138 reaches the wedge stop 136. In various embodiments, as the pivot pin 138 pivots towards the wedge stop 136, the arm 134 can flex, move outward or deform to accommodate the pivot pin 138. Further, when the pivot pin 138 abuts the wedge stop 136 further rotation of the pivot pin 138 can be prevented by the wedge stop 136. Referring still to FIGS. 37-39, clockwise rotation of the pivot pin from the vertical configuration (FIG. 38) can be prevented by the flexible arm 134 and the non-wedged portion of the collar 132. In alternative embodiments, the opening 135 in the collar 132 can permit approximately 20 degrees of rotation, for example. In other embodiments, the opening 135 can permit less than or more than 20 degrees of rotation, for example. Further, in various embodiments, the opening 135 can be configured to permit clockwise rotation and prevent counterclockwise rotation, for example.
In various embodiments, the collar 132 can be more flexible than the pivot pin 138 such that the arm 134 of the collar 132 substantially flexes or deforms and the pivot pin 138 substantially maintains its shape when the pivot pin 138 pivots into and/or against the arm 134. For example, the collar 132 can comprise a sufficiently resilient material, such that the flexible 134 can flex or deform to accommodate the pivot pin 138, and can subsequently return or substantially return to its undeformed position when the pivot pin returns to its initial, non-pivoted configuration. In certain embodiments, the collar 132 can comprise an elastomeric material such as urethane, for example. Further, in certain embodiments, the pivot pin 138 can comprise a substantially rigid material such as brass, for example.
Referring again to FIGS. 32 and 33, in use, the pivot pin 138 can pivot or turn in the collar 130 to adjust the position of the yoke 108 relative to the housing ring 152. For example, the pivot pin 138 can pivot away from the arm 134 toward the wedge stop 136 when the user positions the assembly 20 relative to the user's head and/or neck. When the pivot pin 138 pivots toward the wedge stop 136, the pivot pin 138 can exert a force on the arm 134 such that the arm 134 deforms or flexes to accommodate the pivot pin 138. In various embodiments, the arm 134 can exert a springback force on the pivot pin 138, which can help to maintain the relative positions of the yoke 108 and the housing ring 152, for example. Furthermore, the relative positions of the yoke 108 and the housing ring 152 can help to hold the assembly 20 in position relative to a user's head or neck. For example, the ring housing 152 can be pivoted toward a user's ear, such that the ear cushion 148 of the earpiece 100a exerts a force on the user's ear that comfortably secures the assembly 20 relative to the user's head and/or neck without applying an excessive force thereto. Further, when the assembly 20 is removed from the user's head or neck and/or when the user stops actively adjusting the assembly 20, the arm 134 of the collar 132 can exert a force on the pivot pin 138 that causes the pivot pin 138 to pivot away from the wedge stop 136 and toward the arm 134 such that the housing pivot mechanism 130 pivots the ring housing 152 relative to the yoke 108 and the assembly 20 returns to its initial configuration.
