TECHNICAL FIELD
The technical field relates generally to the field of audio headsets, and more specifically, audio headsets utilized with virtual reality environments.
BACKGROUND
Virtual reality is one method in which people use computers and technology to interact or socialize with others. Virtual reality is a computer-generated simulation of a two or three-dimensional image or environment that can be interacted with by a person using special electronic equipment, such as a helmet with a screen inside or other devices filled with sensors. Users also use other computer systems which include traditional speakers and surround sound speakers. Often, individuals believe that virtual reality environments seem unrealistic. One of the reasons people find virtual reality environments unrealistic is that the sound emitting from the virtual reality environments is unrealistic because of the lack of depth perception and perspective associated with the sound. Because of the unrealistic nature of the sound, many people do not find virtual reality environments enjoyable.
Traditional headsets or headphones use a two dimensional perspective or fixed directional transfer of sound waves. One problem with traditional headsets in virtual reality environments is that the two dimensional perspective or fixed directional transfer of sound waves makes the headphones limited in enabling a listener to locate the source of the sound. Another problem with traditional headsets is that the sound does not adjust based upon the movement of a user's avatar within virtual reality environments. With the prior art, the level of audio capability and quality required currently require powerful high performance gaming computers and CPU resources that are difficult to achieve on standard computers or mobile phones. In addition, traditional headphones are designed for discrete predefined scenarios, not real-time dynamic lifelike experiences, thus the level of immersion within a virtual reality or augmented reality environment is less effective.
Therefore, a need exists for improvements over the prior art. There is also a need for methods and systems that make the sound of the virtual reality experience more realistic.

The system also includes transmitting, over the communications network 107, audio content, visual content and metadata for presenting on the displaying device at each terminal of the plurality of terminals.
Each consumer may navigate a corresponding avatar through the multi-dimensional virtual reality environment using the virtual reality device. In one embodiment, the virtual reality device may be a consumer virtual reality device such as goggles, a heads up display or other input-output device. In another embodiment, the display device may include the OCULUS RIFT, Samsung Gear VR and other head mounted devices. The virtual reality devices may also include various sensors, detectors and output devices that allow the consumer a more lifelike experience when interacting with other consumer's avatars in the virtual reality environment.
In one embodiment, the displaying device may include a monitor for the user to view the virtual environment and a console for such user to influence or navigate avatars in the environment. Each user may navigate a corresponding avatar through the virtual reality environment using the computer system. User 102 may use an avatar known as a first avatar. The system may be configured to identify a first avatar position of a first user when user 102 is navigating the system. The first avatar position may be defined as the location of the first user's avatar within the virtual reality environment and such location may be defined by a set of data, algorithms, program logic comprising computer source code, scripting language code or interpreted language code that perform various functions of the present invention, or any other means known to those skilled in the art.

Additionally, the headband may comprise material such as plastic, polymers, and such material are well known to those skilled in the art. In other embodiments, the ear cup may be an earpiece adapted to fit within a portion of the ear. Such ear pieces are well known to those skilled in the art.
A microphone 235 can be commutatively coupled with the headband. In another embodiment the microphone is not coupled to the headset. The microphone is adapted for receiving a plurality of sound waves. The microphone converts the sound waves into an audio signal. The audio signal is then transmitted and received by a microphone processing module. The microphone processing module then processes the microphone audio signal and converts the microphone audio signal into a voice data packet. The voice data packet includes a plurality of data corresponding to the characteristics of the sound wave received by the microphone. The voice packet may also include sound data (first distance, first positioning, and emitting orientation) of the object within the virtual reality environment. The microphone processing module can then transmit the voice data packet, via the communications network 107, for presenting on an emitting device or computer system remote from the microphone's location. Such a displaying device can include speakers, headsets, computers, or another other device or emitting sound.
A boom 230 having a first end 233 opposing a second end 237 communicatively couples the microphone to the headset. The first end of the boom is attached proximate to one of the ear cups. The microphone is attached at the second end of a boom. It is understood that the term earpiece an ear cup may be used interchangeably.
The computer system also includes a sound processing module for receiving a plurality of sound data, via the communications network 107, associated with a virtual reality environment. The sound data corresponds to sound waves. In one embodiment, the sound data can correspond to the characteristics of sound and position data of an object or avatar within the virtual reality environment, including sound pitch, quality, loudness, position of object, depth, range, perspective and distance of the actual sound as if it existed in the natural originating environment or within a virtual reality environment.
In one embodiment, the sound data includes data for representing a first distance, a first positioning, and a second object emitting orientation. The first distance is a perceived dimension between a first avatar position of said user and a second avatar position of a second sound emitting object or source. For example, a first avatar position within the virtual reality environment can correspond to a first user. A second avatar position within the virtual reality environment corresponds to a second user. The first positioning is the location where the first avatar position is orientated relative to the second avatar position within the virtual environment. The second emitting orientation is a direction sound emanates from the second sound emitting object or source. For example, if a second sound source is faced away from a receiver then the sound waves generated by the sound source are perceived a certain way by the receiver due to the orientation of the sound source. Similarly, in one embodiment of the present invention, sound data will include orientation data such that emulates lifelike perception of sound based upon the second object emitting orientation relative to the first avatar position of a user within the virtual reality environment.
The sound processing module is configured for calculating data representing a first distance, first positioning, and second emitting orientation. The sound processing module uses digital signal processors, computer software and other processes and devices to process the sound data. The sound processing module then converts said plurality of data into a set or plurality of audio signals each having a plurality of channels. Each of these audio signals are then transmitted to each driver (not shown) of each ear cup 220.
The computer system also includes a headset haptic device (not shown). The haptic device is positioned along the headband 215 and each of the ear cups 220 and is adapted so that vibrations, forces and motions can be delivered to users when the computer system is worn by a user. The haptic device may include a shaker that is adapted for such producing vibrations, forces, or motions that are adapted to be received by a user. In one embodiment, the shaker may include a haptic motor or other similar device known to those skilled in the art. The haptic device is adapted for receiving a plurality of audio signals corresponding with the sound profile associated with the virtual reality environment. Each audio signal corresponds to sound waves received at a remote location and then processed into an audio signal or can correspond to the sound data converted by the sound processor of the computer system.
The audio signals include data corresponding to the sound quality, loudness and pitch and position of a sound emitting source or object within the virtual reality environment. The sound profile may also include sound data corresponding to the virtual reality environment. For example, the sound data of the sound profile may also include environment data that corresponds to a geometric shape, dimension and material defining the virtual reality environment. For example, the sound data corresponding to sound being emitted from a sound source within a virtual reality environment, such as an open air football stadium will be comprised differently than the sound data corresponding to sound the from a small room. Another example is that sound data corresponding to sound emanating from a source within a virtual reality environment including water, such as an indoor pool, will be comprised quite differently than the sound data corresponding to sound being emitted from a source within a large open field.
The haptic headset device may include a processor that converts the plurality of audio signals into a haptic profile corresponding to the sound data. The haptic profile includes the vibrations, forces and motions associated or that correspond to sound data. The haptic headset device also transmits vibrations corresponding with the haptic profile from the headset haptic device through the headband 215 to the crown of the user's skull and from each ear cup or earpiece 220 to the skull around each user's ears.
