Description

AUDIO HEADSET

FIELD OF THE INVENTION

[0001] The present invention relates generally to the field of audio headsets, and more particularly to a headset including improved comfort and functionality.

BACKGROUND

[0002] Headphones are often used to output audio to a user via a pair of ear cups. Similar to headphones, headsets typically output audio to a user and also include a microphone to, for example, facilitate communicating with others.

[0003] Headsets may be used for various applications, such as video gaming. Video games have become increasingly complex and allow gamers to play against individuals via the internet. In addition to the visual aspects of the video games, audio plays an important part in providing the gaming experience. Usually, a gamer will wear a headset that provides game audio to the user's ears, as well as includes a microphone to allow the gamers to communicate with each other.

[0004] Game audio often refers to audio generated by a video game, usually during game play. Such audio may include musical soundtracks, sound effects, and other audio. The importance of game audio often depends on the type of video game or the type of interactions involved. For example, in puzzles games, audio may serve to enhance the game play but may not be crucial for proper gamer interaction with the video game. In contrast, game audio may play an important or even crucial role in achieving favorable results for certain video games. For instance, the ability to hear sounds of the surrounding gaming environment may be important in a first-person shooter. Examples of audio that gamers rely on may include footsteps of approaching enemies, doors opening, vehicles, and other game audio. Based on the audio received, a gamer may, for example, communicate with teammates, anticipate their next move, determine their next response, or perform a certain action.

[0005] With the increased depth and complexity of video games, users may wear a headset for prolonged or extended periods of time. However, wearing conventional headphones for many hours may cause ear fatigue and discomfort. One major discomfort results from the temperature increase around the gamer’s ear after a period of use. This discomfort grows as the length of continuous use extends. In addition, most headsets often do not sufficiently exclude ambient noise.

[0006] Conventional headsets also often include fixed constructions such that there is little or no opportunity to easily upgrade or interchange individual components. As a result, conventional headsets may be difficult to repair and may require replacement after a limited number of uses.

[0007] Therefore, there is a need for an improved headset.

SUMMARY

[0008] The present invention relates generally to the field of audio headsets, and more particularly to a headset including improved comfort and functionality

[0009] In one aspect, the headset may include one or more earcup assemblies and a headband assembly. The headband assembly may include a bracket having one or more slots. Each slot of the bracket may be configured to receive a locking mechanism. The locking mechanism may be operable for adjusting a distance between the headband assembly and the one or more earcup assemblies. Further, the headset may include a post that is pivotally attach to an earcup assembly and the locking mechanism to facilitate pivotal movement of the earcup assembly with respect to the headband assembly.

[0010] The headband assembly may further include a cushion assembly removably coupled to the bracket. In addition, the cushion assembly may be configured to connect to one or more stoppers of the headband assembly. The cushion assembly may include a top section detachably coupled to a bottom section via, for example, a hook and loop fastener. The top section may include a channel for guiding a flat wire.

[0011] The locking mechanism of the headset may be a cam assembly including a housing and thumb pad. The housing may contain a cam and a lockpad. The thumb pad may include a rod having a pin that is configured to interface with the cam. In operation, when thumb pad is rotated, locking mechanism may be configured to compress and secure to the bracket. When unlocked, the user may adjust a distance between the headband assembly and the earcup assembly.

[0012] The earcup assemblies of the headset may include a frame, a driver assembly, and an earpad. The driver assembly may be detachably connected to the frame. The earpad may be detachably connected to the driver assembly. As a result, a user may easily interchange various components of each earcup assembly.

[0013] It is also contemplated that the earpad is formed of one or more layers. One layer may be configured to cover the remaining layers and formed of an acoustically absorbent material, such as alcantara. Another layer may be a memory foam layer that provides additional comfort to a user. Yet another layer may be a cooling layer, such as a cooling gel to, for example, reduce ear fatigue and discomfort. [0014] The earcup assembly may further comprise a bayonet mount configured to couple with a corresponding bayonet fastener. In addition, the earcup assembly may include an input port. For example, one earcup assembly may include a first input port configured to couple with an audio source and the other earcup assembly may include a second input port configured to couple with a microphone.
