Description

Background Art

[0001] The present disclosure relates to headphones. Summary of the invention

[0002] All examples and features mentioned below can be combined in any technically possible way.

[0003] In one aspect, a headphone includes a pad assembly, a slider telescopically received within the pad assembly, and an earphone. A bracket couples the earphone to the slider. A pivot is disposed at an open end of the slider and couples the bracket to the slider. The pivot includes a barrel received within an opening in the bracket. The barrel is secured within the opening via a pin inserted into a hole in the bracket.

[0004] Implementations may include one or any combination of the following features.

[0005] In some implementations, the hole extends substantially parallel to the opening.

[0006] In certain implementations, the pin does not extend into or through the barrel.

[0007] In some cases, a pin limits rotational movement of the bracket relative to the pivot.

[0008] In some implementations, the pivot has a ridge extending outwardly from the barrel, and the recess terminates at a groove in the bracket within which the ridge moves when the bracket rotates relative to the pivot.

[0009] In some cases, the opening is provided with a recess that allows the protrusion to enter the opening and into the groove.

[0010] In some cases, after assembly, the pin prevents the protrusion from rotating into alignment with the recess, thereby preventing the bracket and pivot from separating.

[0011] In some examples, the groove extends only partially around the opening, thereby limiting the amount of relative rotation between the bracket and the pivot.

[0012] In some examples, the barrel is hollow with a through hole extending therethrough, and wiring for powering the earphones is received in the through hole.

[0013] In some implementations, the bracket defines a channel for routing wiring to the headset.

[0014] In some implementations, the earphones cover and hide the channels.

[0015] In some cases, the cradle includes first and second bosses that engage the earphone to provide a pivot axis about which the earphone can pivot relative to the cradle.

[0016] In some cases, a channel extends through the first protrusion for routing wiring to the earphone.

[0017] In some examples, the first raised portion includes a rib that engages a recess formed in the earphone to limit rotation of the earphone relative to the bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] For the purpose of explanation, components generally labeled in the drawings are considered to be substantially equivalent components, and redundant discussion of those components is omitted for clarity. The numerical ranges and values ​​described according to various embodiments are merely examples of such ranges and values ​​and are not intended to limit these embodiments. In some cases, the term "about" is used to modify a value, and in these cases, may refer to a value + / - a margin of error (such as measurement error), which may be in the range of up to 1% to 5%. DETAILED DESCRIPTION

[0033] Figure 1 A headset 100 is shown. The headset 100 includes a headband 102, which includes a flat tubular cushion assembly 104, which is constructed and arranged to be placed above the top of a person's head. Tubular sliders 106a and 106b (collectively referred to as "106") support earphones 108a and 108b (collectively referred to as "108"). The slider engages with the cushion assembly 104 in a manner that allows the slider to move in and out of the cushion assembly to adjust the overall length of the headband so that the headset can be comfortably worn on, in or above the ear of the wearer. This overall arrangement of the headset is known in the art. Moreover, in some cases, a microphone (not shown) may be included so that the headset can be used as a headset. In addition, some headphones or headsets only include one earphone, in which case only one slider may be present.

[0034] The cushion assembly 104 is preferably generally tubular. This arrangement allows the slide to be received within the volume on the inside of the tube and also allows wiring to pass along the length of the cushion assembly. The slides 106a and 106b are partially positioned within this internal volume of the cushion assembly. Each slide has a proximal end 110a, 110b (e.g., end 110a of slide 106a) and a distal end 112a, 112b (e.g., end 112a of slide 106a) positioned in the cushion assembly. Connecting members 114a and 114b (collectively referred to as "114") are pivotally connected to the slide 106. The connecting members each carry an earphone 108 (also known as a "headset") at its distal end. At Figure 1 1 and 108b are shown. Each of the earphones 108 includes an ear pad 109 and a supporting electroacoustic transducer 113 ( Figure 2 ) earmuffs 111.

[0035] The slides are preferably, but not necessarily, generally hollow tubes having a generally flat outer surface closest to the head. In the example shown in the drawings, the slide 106a has a flat outer surface 141 of the lower half 140 of the slide tube. The pivot axis 50 defined by the shaft 130 is located below and generally parallel to the surface 141. The slide can have an elliptical cross-sectional shape, such as an elliptical stadium (also known as a "racetrack"), an oval, or an elliptical shape.

[0036] exist Figure 2 One example of a coupling member 114b is shown in more detail in FIG. Figure 2 A left coupling member 114b is shown. A mirror image of this design will be used for the right coupling member 114a. Coupling member 114b includes a bracket 116 having legs 118 and 120 that carry the earphone 18. The earphone coupling member (also referred to as "first and second protrusions 1010 and 1012") Fig. 10A )) is coupled to the earphone 108b and allows it to rotate around the axis 122. Moreover, the coupling member 114b is engaged with the slider 106b in a manner that allows the bracket to pivot around the axis 124.

[0037] Conductive cable 126 (also called "wiring") Figure 6) interconnects the earphones 108a and 108b and carries the audio signals played by the earphones. The cable 126 is flexible and passes through the coupling members 114a and 114b, the sliders 106a and 106b, and the cushion assembly 104. The cable 126 needs to have a sufficient length to accommodate the two sliders that slide out of the cushion assembly to their end points, and also allow the earphones to move from the deployed position to the stowed position. At the same time, the cable 126 needs to be managed so that it is less likely to bunch or pinch during use.

[0038] Unlike some conventional circum-aural headphone products that include plastic brackets, the headphone 100 may include machined metal brackets. This may provide a desirable look and feel, but unlike the plastic brackets used in some prior art headphones (which can be elastically deformed to fit around the ear cups during assembly), these metal brackets are not flexible. Therefore, a different way of coupling these brackets to the ear cups may be required.

[0039] Pivot attachment

[0040] refer to Figure 3 , a pivot mount 300 is disposed in each of the slides 112. The pivot mount 300 is a U-shaped plastic component having two arms 302, each of which defines a pivot pin 402 ( Figure 4 ) groove 304. Figure 4 A pivot 400 is shown mounted to the pivot mount 300 with its pivot pin 402 resting in the groove 304. The arm 302 further defines a pair of cavities 306 for receiving silicone dampers 404. The silicone dampers create friction to provide a damped feel when the pivot is folded, and they also help center the pivot within the slide.

[0041] Figure 5 and Figure 6 The pivot and pivot mount subassembly is shown inserted into the open end of a corresponding one of the slides 106. The slide 106 is generally in the form of a hollow tube (e.g., extruded aluminum). The walls of the slide 106 hold the pivot pin 402 and silicone damper 404 in place in corresponding recesses in the pivot mount 300. The slide 106 defines a slot (or notch) 500 that allows the pivot to rotate about the pivot pin 402 relative to the slide 106. As shown in FIG. Figure 6 As shown, the pivot axis 200 is off-center, which allows a conductive cable (not shown) to reach far side of the pivot axis 200, which is beneficial because it hides the cable from the outside when the pivot is folded.

[0042] refer to Figure 7The pivot and pivot mount subassembly is secured in position within the slide 106 by a pair of pivot mount caps 700 secured to the arms 302 of the pivot mount 300 by a pair of screws 702 ( Figure 3 ) at the free end. Figure 8 The pivot mount cap 700 is shown as being generally T-shaped. Each of the pivot mount caps 700 includes a ridge 802 configured to engage a corresponding groove 502 ( Figure 5 ). The pivot mount cap 700 is installed by rotating (pivoting) the pivot 400 away from the open end of the slide 106 and inserting the pivot mount cap 700 near the center of the open end of the slide 106, and then pushing the pivot mount cap 700 out to the side so that the ridge 802 engages the groove 502 in the wall of the slide 106. Once the pivot mount cap 700 is in place, the screw 702 is installed to prevent the pivot mount cap 700 from moving. Thus, the screw that holds the assembly in place is arranged at the open end of the slide 106, and therefore, the bracket 116 ( Figure 2 ) has been installed and the hardware is hidden to help provide the headset with a seamless appearance without visible fasteners.

[0043] The pivot mount cap 700 also serves another purpose. In this regard, the pivot mount cap 700 protrudes slightly (above flush) from the end of the slide 106 and provides a surface for the aluminum bracket 116 to rub against, thereby preventing aluminum-on-aluminum contact between the bracket 116 and the slide 106, such as Fig. 9 shown.

[0044] Bracket attachment

[0045] Fig. 10A and Fig. 10B One of the right brackets 116 is shown (a mirror image of this design will be used for the other bracket). Bracket 116 includes a top surface 1002 that is pivoted via pivot 400 ( Figure 7 ) to cooperate with a corresponding one of the sliders 106 of the headband 102. An opening 1003 having a recess 1004 is provided in the top surface 1002 of the bracket 116. The recess 1004 terminates at a groove 1006 within the opening 1003. The groove 1006 extends partially around the opening 1003. The mating portion on the pivot 400 has a ridge 602 ( Figure 6), which is sized to fit in recess 1004. During assembly, pivot 400 is inserted into opening 1003, and bracket 116 is then rotated relative to pivot 400 so that protuberance 602 moves in groove 1006. Because groove 1006 only partially extends around opening 1003, there is a rotational limit.

[0046] The hole 1008 extends from the top surface 1002 of the bracket 116 to the second opposing surface 1102 ( Fig.11 ). With the pivot 400 inserted into the opening 1003 and the bracket 116 rotated so that the protrusion 602 rotates within the groove 1006 and is misaligned with the recess 1004, the pin 1104 ( Fig.11 ) is inserted from the second surface 1102 into the hole 1108. The pin 1104 prevents the protrusion 602 from rotating back into alignment with the recess 1004, thereby locking the protrusion within the groove 1006 and preventing the bracket 116 from separating from the pivot 400 and the slide 106.

[0047] The second surface 1102 is located within a channel 1106 in the bracket 116 and is used to pass a conductive cable (not shown) through the ear cup 111 ( Fig.12 ). Once the ear cup is mounted to the bracket 116, the ear cup covers and thus hides the conductive cable and the pin 1104. Thus, the hardware (i.e., the pin 1104) and the conductive cable are hidden after the ear cup has been mounted to help provide the headset with a seamless appearance with no visible fasteners or wires.

[0048] Earmuff attachment

[0049] See again Fig. 10A , the exemplary bracket 116 has first and second protrusions 1010 and 1012, respectively (also referred to as "headphone coupling members") that engage the earmuff 111 ( Fig.12 ) to provide a pivot axis 200 ( Figure 2 ), the earmuff 111 can pivot relative to the bracket 116 around the pivot axis. Fig.13 As shown, the first raised portion 1010 has a semicircular cross-section with a channel 1302 passing through the semicircular cross-section. The channel 1302 is connected to the channel 1106 in the associated arm 120 of the bracket 116 for passing a conductive cable (not shown) to the earmuff 111. The rib 1304 extends outwardly from the raised portion 1010. See again Fig. 10A The second protrusion 1012 is generally in the shape of a hollow cylinder.

[0050] refer to Fig.14A and Fig. 14BThe earmuff 111 has a first groove and a second groove 1402 and 1404, respectively, for receiving the protrusions 1010 and 1012 ( Fig. 10A The first groove 1402 and the second groove 1404 are designed so that the protrusions 1010 and 1012 can slide into the grooves 1402 and 1404 without deforming the bracket 116.

[0051] like Fig.14A As shown, the first groove 1402 includes a recess 1406 for receiving the rib 1304 ( Fig.13 The recess 1406 is shaped to limit the rotation of the ear cup 111 by defining a hard stop for the rib 1304. The first hole 1408 ( Fig. 14B ) extends through the first groove 1402 and is aligned with the channel 1302 ( Fig.13 ) to allow wiring to pass therethrough for powering the ear cup 111.

[0052] refer to Fig. 14B The second hole 1410 extends through the second groove 1410 and is arranged to align with the threaded hole 1014 ( Fig. 10A ) is aligned. Fig.12 As shown, the screw 1202 is inserted from the interior 1204 of the earmuff 111 through the second hole 1410 and screwed into the threaded hole 1014 ( Fig. 10A ), thereby securing the earmuff 111 to the bracket 116. The interior 1204 of the earmuff 111 is covered by other components (not shown) during assembly, and therefore, the screws are hidden to help provide a headset with a seamless appearance without visible fasteners.
