Abstract

Headphone assemblies, related components such as headband assemblies and ear cup assemblies, and methods of operation and assembly are disclosed herein. Some of the headphone assemblies include a headband assembly and a first and second ear cup assembly, the ear cup assemblies having attachment mechanisms adapted to reversibly mate with counterpart attachment mechanisms in the headband assembly such that the ear cup assemblies can each be readily replaced or exchanged, and such that each ear cup assembly connects mechanically and electrically to the headband assembly. Some of the headphone assemblies include one or more cambering features that cause an attachment mechanism on the headphone assembly, or a first reference plane defined by an inwardly-facing surface of the first ear cup assembly, to change its orientation relative to the headband assembly or a first arm thereof, in response to pivotal or extensible articulation of the headband assembly over a range of motion.

Claims

1. A headband assembly for use in a headphone, the headband assembly comprising:

an electronics section;

a battery section electrically coupled to the electronics section;

a first headband attachment mechanism disposed at a first end of the headband assembly; and

a second headband attachment mechanism disposed at a second end of the headband assembly, the second end being opposed to the first end of the headband assembly;

wherein each of the first and second headband attachment mechanisms is configured to detachably connect to an ear cup assembly and provide an electrical connection from the ear cup assembly to the electronics section.

2. The headband assembly of claim 1, wherein the electronics section includes one or more electronic components, the one or more electronic components including at least one of a microprocessor, an amplifier, and an antenna.

3. The headband assembly of claim 2, wherein the battery section is wired to energize at least one of the one or more electronic components when a suitable battery is present in the battery section.

4. The headband assembly of claim 1, wherein the electronics section and the battery section are disposed in separate compartments on or in the headband assembly.

5. The headband assembly of claim 1, wherein the electronics section and the battery section are disposed in a same compartment on or in the headband assembly.

6. The headband assembly of claim 1, wherein the first headband attachment mechanism includes a first male or female multi-pin electrical connector, and the second headband attachment mechanism includes a second male or female multi-pin electrical connector.

7. The headband assembly of claim 1, wherein the headband assembly includes a C-shaped main headband body and a first and second arm extending from opposite ends of the main headband body, the main headband body including the electronics section and the battery section, the first arm including the first headband attachment mechanism, the second arm including the second headband attachment mechanism, the headband assembly further comprising:

one or more first cambering features that cause the first headband attachment mechanism to change its orientation relative to the first arm in response to pivotal or extensible articulation of the headband assembly over a range of motion; and

one or more second cambering features that cause the second headband attachment mechanism to change its orientation relative to the second arm in response to the pivotal or extensible articulation of the headband assembly over the range of motion.

8. The headband assembly of claim 7, wherein a rotational axis passes through the first and second headband attachment mechanisms, and wherein the one or more first cambering features cause the first headband attachment mechanism to rotate about a first secondary axis in response to pivotal articulation of the headband assembly about the rotational axis, and the one or more second cambering features cause the second headband attachment mechanism to rotate about a second secondary axis in response to the pivotal articulation of the headband assembly, the first and second secondary axes each being perpendicular to the rotational axis.

9. The headband assembly of claim 7, wherein the first and second arms slidingly engage the main headband body to provide extensible articulation of the headband assembly between an extended configuration and a retracted configuration, and wherein the one or more first cambering features cause the first headband attachment mechanism to change its orientation relative to the first arm in response to the extensible articulation, and the one or more second cambering features cause the second headband attachment mechanism to change its orientation relative to the second arm in response to the extensible articulation.

10. A headphone assembly, comprising:

the headband assembly of claim 1;

a first ear cup assembly detachably connected to the first headband attachment mechanism; and

a second ear cup assembly detachably connected to the second headband attachment mechanism.

11. The headphone assembly of claim 10, wherein the first headband attachment mechanism includes a first male or female multi-pin electrical connector, and the first ear cup assembly includes a first female or male multi-pin electrical connector that reversibly mates with the first male or female multi-pin electrical connector.

12. A headphone assembly, comprising:

a headband assembly including;

an electronics section;

a battery section electrically coupled to the electronics section; and

a first and second headband attachment mechanism;

a first ear cup assembly having a first ear cup attachment mechanism adapted to reversibly mate with the first headband attachment mechanism to mechanically and electrically connect the first ear cup assembly to the headband assembly; and

a second ear cup assembly having a second ear cup attachment mechanism adapted to reversibly mate with the second headband attachment mechanism to mechanically and electrically connect the second ear cup assembly to the headband assembly.

13. The headphone assembly of claim 12, wherein the first and second ear cup assemblies rotationally engage the headband assembly to provide rotational articulation of the headband assembly over a rotational range of motion from an over-head configuration to a behind-head configuration.

14. The headphone assembly of claim 12, wherein the headband assembly includes a C-shaped main headband body and a first and second arm extending from opposite ends of the main headband body, the main headband body including the electronics section and the battery section.

15. The headphone assembly of claim 14, wherein the first and second arms slidably engage the main headband body to provide extensible articulation of the headband assembly over a translational range of motion from a fully extended configuration to a fully retracted configuration.

16. The headphone assembly of claim 14, wherein the first arm includes the first headband attachment mechanism and the second arm includes the second headband attachment mechanism, and wherein the first and second ear cup assemblies have a respective first and second inwardly-facing surface that define a respective first and second reference plane, the headband assembly further comprising:

one or more first cambering features that cause the first reference plane to change its orientation relative to the first arm in response to pivotal or extensible articulation of the headband assembly over a range of motion; and

one or more second cambering features that cause the second reference plane to change its orientation relative to the second arm in response to the pivotal or extensible articulation of the headband assembly over the range of motion.

17. The headphone assembly of claim 12, wherein the headband assembly also includes an inductive coil coupling section coupled to the battery section.

18. A headphone assembly, comprising:
