     FIELD OF USE 
     The present disclosure relates generally to devices, systems, and methods for electronic soundbars, and more specifically to a noise cancelling soundbar system which creates semi-soundproof zones for its nearby users without requiring the use of headphones or expensive soundproofing insulation. 
     BACKGROUND 
     Soundbars are a popular accessory for use with TVs and other audiovisual media devices due to their small form factor, powerful sound, and ease of installation. Soundbars allow users to customize their home entertainment setup and greatly enhance the audio output of their media devices without taking up much space. In particular, soundbars are frequently used to enhance the sound of flat screen TVs, which often do not have the physical device space available for a powerful built-in speaker system. 
     However, while commercial soundbars provide an enhanced viewing and listening experience for persons engaged in watching and/or listening to the media being played, this same powerful audio may also bother or annoy people in the same or close rooms who are not interested in viewing the media at that moment. This is a very common problem in crowded apartment complexes, for example, where the sounds of one person&#39;s soundbar-augmented audio can easily spill over into a neighboring apartment. This overflow noise can be especially problematic within a single residence, as loud sounds from media can easily annoy roommates, family members, or other house guests. 
     To avoid this situation of unwanted spillover noise, the person wanting to listen to audiovisual media essentially has three options: (1) lower the media and/or soundbar volume; (2) wear headphones; or (3) soundproof the media viewing area (such as a living room or bedroom). However, none of these solutions are very satisfying. 
     As to the first option: Lowering the media/soundbar volume often results in the viewer&#39;s enjoyment being substantially reduced, especially when the volume must be lowered to a level that the audio can no longer be heard clearly. In many cases, lowering the volume may not be an effective or practical solution at all, such as when trying to watch TV without disturbing a nearby sleeping partner. In this case, the volume would need to be so low as to be virtually silent. 
     As to the second option: While headphones generally allow a person to listen to media at an enjoyable volume without disturbing nearby persons, they are often uncomfortable when worn for prolonged periods of time. Headphones are particularly uncomfortable if worn to bed, as may be attempted when trying to listen to music or watch a show without disturbing a nearby sleeping partner who has fallen asleep or is trying to fall asleep. 
     As to the third option: Soundproofing one&#39;s home or room(s) is often prohibitively expensive. Additionally, soundproofing an individual room does nothing to address potential sound overflow issues within the same room, where spillover audio may still disturb nearby non-listeners. 
     Thus, what is needed is a convenient, comfortable, and affordable way for users to enjoy audiovisual media without disturbing non-listeners nearby, without having to wear headphones. 
     SUMMARY 
     To minimize the limitations in the cited references, and to minimize other limitations that will become apparent upon reading and understanding the present specification, the present specification discloses a new and improved noise cancelling soundbar device and system. 
     In one embodiment, the noise cancelling soundbar of the present disclosure may comprise a loudspeaker, an integrated power amplifier, and an audio input communication module. Preferably, the noise cancelling soundbar may combine multiple audio-related technologies into a form factor specifically optimized for use in bedrooms. However, the noise cancelling soundbar may be used in any environment where a controlled auditory space is desired, such as living rooms, dining rooms, or office spaces. 
     In one embodiment, the noise cancelling soundbar may comprise one or more loudspeakers, an integrated power amplifier, and an audio input communication module. The noise cancelling soundbar may be configured to receive an audio signal input from a media source, such as a TV, smartphone, or other device, and play the audio signal from the one or more loudspeakers. In one embodiment, the one or more loudspeakers may preferably be adjustable via an actuator, which allows the one or more loudspeakers to be rotated or pivoted to precisely aim the audio output of the noise cancelling soundbar. By carefully positioning the noise cancelling soundbar and the one or more loudspeakers, it is possible to greatly reduce the level of sound required for the loudspeaker output sounds to be heard from a listener, reducing the amount of unwanted audio “spillover” which may disrupt nearby persons. 
     For example, existing soundbars are commonly installed directly underneath a TV screen. When a user sits some distance from the TV, such as on a couch or bed across the room, the audio output of the soundbar must be loud enough to be heard by the user from across the room. By contrast, the noise cancelling soundbar of the current disclosure may be installed within a headboard of a bed or headrest of a couch, such that a listener watching TV from his or her bed (or couch) requires a much lower loudspeaker output volume, due to the smaller distance between the soundbar loudspeakers and the listener&#39;s ears. The actuators may be used to directionally adjust the one or more loudspeakers, such that the one or more loudspeakers may aim directly at the listener&#39;s ears and reduce the required loudspeaker audio output level even further. 
     One embodiment may be a noise cancelling soundbar system, comprising a first noise cancelling soundbar and a second noise cancelling soundbar. Preferably, each noise cancelling soundbar may comprise one or more loudspeakers, an audio input communication module, one or more microphones, and an active noise cancellation module. The first and second noise cancelling soundbars may be used in connection with each other to create a semi-soundproofed listening zone at each individual noise cancelling soundbar. 
     The one or more microphones may be used to measure nearby ambient noise. The measured ambient noise may then be processed by the active noise cancellation module, such that a negative sound output pattern is generated. In a preferred embodiment, any ambient noise in the vicinity of the first noise cancelling soundbar (including sounds that are not generated by the first noise cancelling soundbar, such as snoring by a user of the first noise cancelling soundbar) may be measured by the one or more microphones on the first noise cancelling soundbar. The second noise cancelling soundbar may then communicate with the one or more microphones of the first noise cancelling soundbar to obtain accurate ambient noise data present in a vicinity of the first noise cancelling soundbar. The second noise cancelling soundbar may then process the ambient noise data with an active noise cancellation module, to produce a negative sound output pattern that is specifically designed to cancel out the ambient noise emanating from the vicinity of the first noise cancelling soundbar. The one or more loudspeakers of the second noise cancelling soundbar may then play the negative sound output pattern, such that the negative sound output pattern destructively interferes with the sound waves of the ambient noise. In this manner, the second noise cancelling soundbar may insulate a user of the second noise cancelling soundbar from the ambient noise in the vicinity of the first noise cancelling soundbar. 
     The first noise cancelling soundbar may use the corresponding microphones, active noise cancelling module(s), and loudspeakers to similarly insulate a user of the first noise cancelling soundbar from ambient noise pertaining to the second noise cancelling soundbar. As a result, each user of a noise cancelling soundbar may listen (or not) to the media of their choosing without disturbing the user of the other soundbar. 
     Each noise cancelling soundbar may preferably be positioned near (which may be in the range of one inch to four feet, or otherwise in close proximity to) a listener&#39;s head/ears, reducing the level of sound required for the user to hear the loudspeaker output audio. Suitable locations for installing a noise cancelling soundbar may include, for example, bedrooms (in a bed headboard), or living rooms and office spaces (in the headrests of couches and chairs). 
     One embodiment may be a noise cancelling soundbar, comprising: one or more loudspeakers, an integrated power amplifier, an audio input communication module, one or more microphones, and an active noise cancelling module; wherein the one or more microphones may be configured to measure ambient noise; wherein the active noise cancelling module may be configured to process the ambient noise, to create a negative output that may be configured to destructively interfere with the ambient noise; wherein the negative output audio may be configured to be emitted from the one or more loudspeakers, such that the ambient noise may be substantially cancelled or reduced, and; wherein the noise cancelling soundbar may be configured to receive an audio signal from one or more media sources and subsequently play the audio signal from the one or more loudspeakers. In another embodiment, the noise cancelling soundbar may further comprise one or more adjustable bases and one or more actuators; wherein the one or more loudspeakers may be mounted on the one or more adjustable bases; wherein the one or more actuators may be configured to adjust the one or more adjustable bases. The noise cancelling soundbar may be installed in any environment with sufficient space, including, but not limited to, the headboard of a bed or the back of a chair. Preferably, the one or more adjustable bases may be configured to direct the audio output signal from the one or more loudspeakers to a listener laying in the bed and/or chair. 
     One embodiment may be a noise cancelling soundbar system, comprising: a first noise cancelling soundbar and a second noise cancelling soundbar, wherein the first and second noise cancelling soundbars may each individually comprise, respectively: a first/second set of one or more loudspeakers; a first/second audio input communication module; at least one first/second ambient microphone; at least one first/second near field microphone, and a first/second active noise cancellation module. In a preferred embodiment, the first noise cancelling soundbar and the second noise cancelling soundbar may be configured to be integrated into opposite sides of a headboard of a bed that is configured to be used by two listeners. The at least one first ambient microphone and the at least one second ambient microphone may be on opposite distal ends of the headboard. The at least one first near field microphone and the at least one second near field microphone may be proximate to each other at a middle portion of the headboard, and be configured to, respectively, measure a first and second nearfield noises coming from an opposite side of the bed, wherein the at least one ambient microphone and the at least one second ambient microphone may be configured to, respectively, measure a first ambient noise and a second ambient noise. The first and second ambient noise cancelling modules may be configured to process the first and second ambient noises, such that a first and a second negative output audios are created, which may be configured to destructively interfere, relatively, with the first and second ambient noises. Similarly, the first and second active cancelling modules may be configured to process the first and second nearfield noises, such that a first and second negative output audios are created that may be configured to destructively interfere, relatively, with the first and second nearfield noises. Alternatively, the first and second active noise cancelling modules may be configured to process, respectively, both the first and second nearfield noises and the first and second ambient noises, such that a first and second negative output audios may be created that may be configured to destructively interfere, relatively, with both the first and second nearfield noises and the first and second ambient noises. 
     Regarding the cancellation of ambient audio: the first and second negative output audios may be configured to be respectively emitted from the first and second sets of one or more loudspeakers, such that the first and second ambient noises may be substantially cancelled or reduced. Regarding the cancellation of nearfield audio: the first and second negative output audios may be configured to be respectively emitted from the first and second sets of one or more loudspeakers, such that the first and second nearfield noises may be substantially cancelled or reduced. In some instances, the ambient and nearfield audio may both be substantially cancelled or reduced, wherein the first and second negative output audios may be configured to be respectively emitted from the first and second sets of one or more loudspeakers, such that both the first and second nearfield noises, and the first and second ambient noises may be substantially cancelled or reduced.

     DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS 
     In the following detailed description of various embodiments, numerous specific details are set forth in order to provide a thorough understanding of various aspects of the embodiments. However, these embodiments may be practiced without some or all of these specific details. In other instances, well-known methods, procedures, and/or components have not been described in detail so as not to unnecessarily obscure aspects of the embodiments. 
     While multiple embodiments are disclosed, still others will become apparent to those skilled in the art from the following detailed description. As will be realized, these embodiments are capable of modifications in various obvious aspects, all without departing from the spirit and scope of protection. Accordingly, the graphs, figures, and the detailed descriptions thereof, are to be regarded as illustrative in nature and not restrictive. Also, the reference or non-reference to a particular embodiment shall not be interpreted to limit the scope of protection. 
     In the following description, certain terminology is used to describe certain features of one or more embodiments. For purposes of the specification, unless otherwise specified, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, in one embodiment, an object that is “substantially” located within a housing would mean that the object is either completely within a housing or nearly completely within a housing. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking, the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is also equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result. 
     As used herein, the terms “approximately” and “about” generally refer to a deviance of within 5% of the indicated number or range of numbers. In one embodiment, the term “approximately” and “about,” may refer to a deviance of between 0.0001-10% from the indicated number or range of numbers. 
     As used in the specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Ranges may be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are signified both in relation to the other endpoint, and independently of the other endpoint. 
     “Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. 
     Throughout the description and claims of this specification, the word “comprise” and variations of the word, such as “comprising” and “comprises,” means “including but not limited to,” and is not intended to exclude, for example, other components, integers or steps. “Exemplary” means “an example of” and is not intended to convey an indication of a preferred or ideal embodiment. “Such as” is not used in a restrictive sense, but for explanatory purposes. 
     Disclosed are components that may be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutation of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems. This applies to all embodiments of this application including, but not limited to, steps in disclosed methods. Thus, if there are a variety of additional steps that may be performed it is understood that each of these additional steps may be performed with any specific embodiment or combination of embodiments of the disclosed methods. 
     The present methods and systems may be understood more readily by reference to the following detailed description of preferred embodiments and the examples included therein and to the Figures and their previous and following description. 
     In the following description, certain terminology is used to describe certain features of one or more embodiments. For purposes of the specification, unless otherwise specified, the term “noise cancelling soundbar” generally refers to a soundbar or array of sound equipment that may be equipped with active noise cancelling technology. 
     “Ambient sound(s)” and “ambient sound waves” refer generally to sounds waves present in the vicinity of a noise cancelling soundbar of the present disclosure. This includes, but is not limited to, electronically generated audio (such as that produced by a loudspeaker in response to an electrical signal) and naturally generated audio (such as that produced by people talking, traffic and construction noises, etc.). 
     “Disruptive Audio” refers to any ambient sound waves that a user of a noise cancelling sound board of the present disclosure is not actively trying to listen to, or is trying to avoid listening to. 
     The terms “negative sound wave(s)” and “negative sound output pattern” refer to machine-generated soundwaves that are calculated to destructively interfere with a counterpart disruptive audio. 
     “Media” refers to any form of audio and/or audiovisual content that includes an audio component for listeners to hear. 
     “View” refers to the act of engaging with audio and/or audiovisual media, regardless of whether the viewer is looking and listening, or only listening. 
     The term “set” generally refers to a group of things, such as loudspeakers, but there may be only one thing in any specific group. 
     Embodiments of the present disclosure generally relate to the field of soundbars. More specifically, the present disclosure relates to a noise cancelling soundbar which, through a combination of a small form factor, targeted audio output, and active noise cancelling, allows its users to listen to audio or audiovisual media without disturbing nearby users. 
     Various embodiments are now described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that the various embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form to facilitate describing these embodiments. It is to be understood that the methods and systems are not limited to specific methods, specific components, or to particular implementations. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. 
       FIG. 1  is an illustration showing a common soundbar setup  100  as used in the prior art. As shown in  FIG. 1 , a soundbar  120  may receive audio input from a media device  110 , such as a TV. The soundbar  120  is installed directly underneath the media device  110 , such that the audio output  140  of the soundbar  120  needs to be loud enough to clearly reach a bed  125 . In many situations, the length of the bed  125  requires that the audio output  140  be turned to such a volume that there is often spillover audio that disturbs the peace and quiet of other people nearby. 
       FIG. 2  is an illustration showing one embodiment of a noise cancelling soundbar setup  200 . As shown in  FIG. 2 , a noise cancelling soundbar  220  may receive an audio input  215  from a media device  210 , such as a television. The audio input  215  may be transmitted to the noise cancelling soundbar  220  wirelessly or with a wired connection. Rather than being installed directly under the media device  210 , the noise cancelling soundbar  220  may preferably be installed directly on, in, or near a headboard  226  of a bed  225 . By placing the noise cancelling soundbar  220  on, in, or near the headboard  226 , the audio output  240  of the noise cancelling soundbar  220  requires a much lower volume in order to be heard by anyone trying to view the programming of the media device  210  while lying down in the bed  225 . While reference is made to a bed  225 , it is to be understood that the noise cancelling soundbar  220  may similarly be installed on or near the headrests of sofas, lounge chairs, etc., to produce the same effect. 
       FIG. 3  is an illustration showing a detailed view of a noise cancelling soundbar system  300 . As shown in  FIG. 3 , the noise cancelling soundbar system  300  may comprise a noise cancelling soundbar  320 , one or more loudspeakers  330 , one or more microphones  340 , a processor  360 , a wireless communication module  370 , and a signal preamplifier  380 . The noise cancelling soundbar  320  may receive an audio input signal  315  from a media device  310 , such as a television (TV), smartphone, tablet, or other device capable of playing audio and/or audiovisual media. The audio input signal  315  may be transmitted to the noise cancelling soundbar  320  wirelessly and be received by the wireless communication module  370 . The audio input signal  315  may, alternatively, be transmitted to the noise cancelling soundbar  320  via a wired connection (not shown). 
     The audio input signal  315  may be enhanced by the signal preamplifier  380 , and then subsequently transmitted to the one or more loudspeakers  330  for broadcasting. The one or more loudspeakers  330  may use the (amplified) audio input signal  315  to create a soundbar output audio  337 . The soundbar output audio  337  may be a faithful reproduction of the audio input signal  315  received from the media device  310 , albeit enhanced. In situations in which the media device  310  includes loudspeakers of its own, the media device  310  loudspeakers may preferably be powered down while the noise cancelling soundbar  320  is in use, such that only the noise cancelling soundbar  320  is generating audible sounds pertaining to the media that the user is viewing. The volume of the soundbar output audio  337  may be controlled by means of a volume control module  390 , which may allow communication with, for example, a remote control. 
     The one or more loudspeakers  330  may be mounted on a rotatable (or otherwise moveable/adjustable) base  335 , which may in turn be controlled by a driver  336 . The moveable/adjustable base  335  may be underneath the one or more loudspeakers  330 , and may be used to adjust the angle of the one or more loudspeakers  330 , thereby adjusting the directional output of the soundbar output audio  337 . In this manner, the one or more loudspeakers  330  may be adjusted such that the soundbar output audio  337  may be precisely aimed (or otherwise directed) at a user&#39;s ears. As a result, a lower volume is required for the soundbar output audio  337  to be clearly heard by the user. 
     The noise cancelling soundbar  320  may further comprise one or more microphones  340 , which may be used to measure ambient noise  327 . The ambient noise  327  may be processed by an active noise cancelling module  375 , to create a negative output audio which may destructively interfere with the ambient noise  327  when combined with the ambient noise  327 . Preferably, the negative output audio may be emitted from the one or more loudspeakers  330 , such that the negative output audio largely cancels out any disruption by the ambient noise  327  to a user of the noise cancelling soundbar  320 . The one or more microphones  340  may be mounted on a rotatable (or otherwise moveable/adjustable) base  335 , which may be used to adjust the angle of the one or more microphones  340  in order to improve the measurement of ambient noise  327 . 
       FIG. 4  is an illustration of another embodiment of a noise cancelling soundbar system  400 . As shown in  FIG. 4 , the noise cancelling soundbar system  400  may comprise a first noise cancelling soundbar  420 . 1  and a second noise cancelling soundbar  420 . 2 . In the follow detailed description, reference numerals ending in “.  1 ” designate that the component is part of the first noise cancelling soundbar  420 . 1 , while reference numerals ending in “0.2” designate that the component is part of the second noise cancelling soundbar  420 . 2 . 
     The first noise cancelling soundbar  420 . 1  and the second noise cancelling soundbar  420 . 2  may each comprise one or more loudspeakers  430 . 1 / 430 . 2 , one or more microphones  440 . 1 / 440 . 2 , a processor  460 . 1 / 460 . 2 , a wireless communication module  470 . 1 / 470 . 2 , and a signal preamplifier  480 . 1 / 480 . 2 , respectively. The first noise cancelling soundbar  420 . 1  and the second noise cancelling soundbar  420 . 2  may each be capable of receiving a first and second audio input  415 . 1 / 415 . 2  from a first and second media device  410 . 1 / 410 . 2 , respectively, amplifying the audio signal, and subsequently emitted the amplified audio through directionally adjustable loudspeakers. In this regard, each soundbar may act similarly to the detailed description provided above for  FIG. 3 . 
     By using one or more noise cancelling soundbars in tandem, the noise cancelling soundbar system  400  provides a uniquely effective way for listeners to soundproof themselves against ambient noise in the vicinity of all interconnected noise cancelling soundbars. For clarity, the following description will focus primarily on the components and features of the first noise cancelling soundbar  420 . 1 . However, unless explicitly stated otherwise, it is to be understood that the second noise cancelling soundbar  420 . 2  may preferably include the same components and features of the first noise cancelling soundbar  420 . 1 . 
     As shown in  FIG. 4 , the first noise cancelling soundbar  420 . 1  may receive an audio input signal  415 . 1  from a media device  410 . 1 , such as a TV, smartphone, tablet, or other device capable of playing audio and/or audiovisual media. The audio input signal  415 . 1  may be enhanced by the signal preamplifier  480 . 1 , and then subsequently transmitted to the one or more loudspeakers  430 . 1  for broadcasting. The one or more microphones  440 . 1  may be used to measure ambient noise  427  for processing by an active noise cancellation module  475 . 1 . By doing so, the first noise cancelling soundbar  420 . 1  may generate a first negative output audio which may destructively interfere with the ambient noise  427 . The first negative output audio may be projected from the first one or more loudspeakers  430 . 1 , as part of the first soundbar output audio  437 . 1 . 
     The ambient noise  427 , which may be measured by the one or more microphones  440 . 1  may include the second soundbar output audio  437 . 2  (i.e., any output audio produced by the noise cancelling soundbar  420 . 2 ), as well as any ambient noise  427  present in the vicinity of the second noise cancelling soundbar  420 . 2 , which was not produced by the second noise cancelling soundbar  420 . 2 . The reverse is true for the one or more microphones  440 . 2  of the second noise cancelling soundbar  420 . 2 . Specifically, the one or more microphones  440 . 2  of the second noise cancelling soundbar  420 . 2  may measure both the first soundbar output audio  437 . 1  and ambient noise  427  present in the vicinity of the first noise cancelling soundbar  420 . 1 . The second noise cancelling soundbar  420 . 2  may then, by means of an active noise cancelling module  475 . 2 , generate a second negative output audio which may destructively interfere with, or neutralize, the first soundbar output audio  437 . 1 . In this manner a person near soundbar  420 . 2  may experience a reduced level of ambient noise, including noise made by the first noise cancelling soundbar  420 . 1 . The second negative output audio may be projected from the second one or more loudspeakers  430 . 2 , as part of the soundbar output audio  437 . 2 . Preferably, the volume of the first and output audio  437 . 1  and the second soundbar output audio  437 . 2  may be controlled by means of a first volume control module  490 . 1  and a second volume control module  490 . 2 , respectively. 
     Alternatively, and/or in addition to, the first and second noise cancelling soundbars may directly communicate with each other to produce more effective negative sound waves for cancelling out unwanted audio. For example, the second noise cancelling soundbar  420 . 2  may directly process the first audio input signal  415 . 1  via the second active noise cancelling module  475 . 2 . The first noise cancelling soundbar  420 . 1  may use a similar method to directly process the second audio input signal  415 . 2 . In this way, each individual soundbar may more effectively produce a negative audio output that is designed to neutralize the (positive) audio output of the other soundbar, enabling users of each individual soundbar to enjoy their respective programming without disturbing other users or having to wear headphones. 
     The ambient noise  427  which may be detected by the microphones to generate counterpart cancelling negative sound waves may additionally include naturally generated noises within the vicinity of the noise cancelling soundbar system  400 , such as a user&#39;s snoring or nearby traffic or construction sounds. In one embodiment, the first and second soundbars may be separately installed in different locations, rather than on a single soundbar support board  420  as shown in  FIG. 4 . For example, the first noise cancelling soundbar  420 . 1  may be installed in or near the headrest of an office chair, with the second noise cancelling soundbar  420 . 2  installed on the outside of the office door housing the office chair. Both soundbars may be activated even without any media device input, instead being used primarily for their ability to detect ambient noise  427  and create negative sound waves that destructively interfere with the ambient noise  427 . The rotatable stands  435 . 1 / 435 . 2  for the loudspeakers and microphones allow for each individual soundbar to be adjusted for optimal ambient noise detection, and aiming of the first and second negative output audios. Preferably, a first driver  436 . 1  and a second driver  436 . 2  may be able to control the movements of the first and second rotatable stands  435 . 2 / 435 . 2 , respectively. 
       FIG. 5  is a schematic view of one embodiment of a noise cancelling soundbar system  500 , providing additional detail on the types of microphones and loudspeakers that may be used. As shown in  FIG. 5 , the noise cancelling soundbar  520  may comprise one or more near-field sensing microphones  541 , one or more ambient sound sensing microphones  542 , one or more tweeter speakers  531 , and one or more mid-range speakers  532 . The one or more near-field sensing microphones  541  and the one or more ambient sound sensing microphones  542  may be used to sense sounds that are near and far from the noise cancelling soundbar  520 , respectively. The one or more tweeter speakers  531  and the one or more mid-range speakers  532  may be used to produce high and mid-low range output audio, respectively. 
       FIG. 6  is an illustration showing one embodiment of a noise cancelling soundbar system that is mounted to a wall. As shown in  FIG. 6 , the system  600  may comprise a noise cancelling soundbar  620  that may receive an audio input  615  from a media device  610 , such as a television. The audio input  615  may be transmitted to the noise cancelling soundbar  620  wirelessly or with a wired connection. Rather than being installed directly under the media device  610 , the noise cancelling soundbar  620  may preferably be installed directly on the wall  627  near the head of a bed  625 . By placing the noise cancelling soundbar  620  on the wall  627  near the head of the bed  625 , the audio output  640  of the noise cancelling soundbar  620  requires a much lower volume in order to be heard by anyone trying to view the programming of the media device  610  while lying down in the bed  625 . While reference is made to a bed  625 , it is to be understood that the noise cancelling soundbar  620  may similarly be installed on or near the headrests of sofas, lounge chairs, futons, and the like, to produce the same effect. 
       FIG. 7  is an illustration showing one embodiment of a noise cancelling soundbar installed into a wall. As shown in  FIG. 7 , the system  700  may comprise a noise cancelling soundbar  720  that may receive an audio input  715  from a media device  710 , such as a television. The audio input  715  may be transmitted to the noise cancelling soundbar  720  wirelessly or with a wired connection. Rather than being installed directly under the media device  710 , the noise cancelling soundbar  720  may preferably be installed directly into the wall  727  at or near the head of a bed  725 . By placing the noise cancelling soundbar  720  in the wall  727  near the head of the bed  725 , the audio output  740  of the noise cancelling soundbar  720  requires a much lower volume in order to be heard by anyone trying to view the programming of the media device  710  while lying down in the bed  725 . While reference is made to a bed  725 , it is to be understood that the noise cancelling soundbar  720  may similarly be installed on or near the head end of sofas, lounge chairs, futons, and the like, to produce the same effect. 
       FIG. 8  is an illustration of one embodiment of noise canceling soundbars showing two noise canceling sound bars connect to each other and a controller. As shown in  FIG. 8 , the noise cancelling soundbar system  800  may comprise at least two noise cancelling soundbars  820  connected to each other wired or wireless  816 , each preferably comprising one or more loudspeakers  830 , one or more microphones  840 , a processor  860 , a wireless communication module  870 , and a signal preamplifier  880 . The noise cancelling soundbars  820  may receive an audio input signal  815  from a media device  810 , such as a television (TV), smartphone, tablet, computer, as shown, or other device capable of playing audio and/or audiovisual media. The audio input signals  815  may be transmitted to the noise cancelling soundbars  820  wirelessly and be received by the wireless communication modules  870 . The audio input signals  815  may, alternatively, be transmitted to the noise cancelling soundbars  820  via a wired connection. 
     The audio input signal  815  may be enhanced by the signal preamplifier  880 , and then subsequently sent or transmitted to the one or more loudspeakers  830  for broadcasting. The one or more loudspeakers  830  may use the amplified audio input signal to create a soundbar output audio  837 , which is only shown in one of the two soundbars  820 , but may be created and sent by both soundbars  820 . The soundbar output audio  837  may be a faithful reproduction of the audio input signal  815  received from the media device  810 , albeit enhanced or otherwise amplified. In some embodiments in which the media device  810  includes loudspeakers of its own, the media device  810  loudspeakers may preferably be powered down while the noise cancelling soundbars  820  are in use, such that only the noise cancelling soundbars  820  generate audible sounds pertaining to the media that the user is viewing through media device  810 . The volume of the soundbar output audio  837  may be controlled by means of a volume control module  890 , which may allow communication with, for example, a remote control. 
     The one or more loudspeakers  830  may be mounted on a rotatable (or otherwise moveable/adjustable) base  835 , which may in turn be controlled by a driver  836 . The rotatable base  835  may be underneath the one or more loudspeakers  830  and may be used to adjust the angle of the one or more loudspeakers  830 , thereby adjusting the directional output of the soundbar output audio  837 . In this manner, the one or more loudspeakers  830  may be adjusted such that the soundbar output audio  837  may be precisely aimed (or otherwise directed) at a user&#39;s ears. As a result, a substantially lower volume is required for the soundbar output audio  837  to be clearly heard by the user. 
     The noise cancelling soundbars  820  may further comprise one or more microphones  840 , which may be used to measure ambient noise  827 . The ambient noise  827  may be processed by an active noise cancelling module  875 , to create a negative output audio which may destructively interfere with the ambient noise  827  when combined with the ambient noise  827 . Preferably, the negative output audio may be emitted from the one or more loudspeakers  830 , such that the negative output audio substantially cancels out any disruption by the ambient noise  827  to a user/s of the noise cancelling soundbars  820 . The one or more microphones  840  may be mounted on a rotatable (or otherwise moveable/adjustable) bases  835 , which may be used to adjust the angle of the one or more microphones  840  in order to improve the measurement of ambient noise  827 . The base  835  may be controlled by drivers  836 . 
     Preferably, the soundbars  820  may be physically connected to each other in a removeable manner. They may operate independently or in concert with each other for one, two, or more users. The soundbars  820  may be mounted or integrated into a wall, a headboard, or other piece of furniture. 
       FIG. 9  is an illustration showing one embodiment of a noise cancelling soundbar system that includes a slave unit. As shown in  FIG. 9 , the noise cancelling soundbar system  900  may comprise a noise cancelling soundbar  920 , which may be connected  916 , wired or wireless, to a noise cancelling soundbar slave device  921 .  FIG. 9  shows that the noise cancelling soundbar  920  and noise cancelling soundbar slave device  921  may each comprise one or more loudspeakers  930 ,  931 , and one or more microphones  940 ,  941 . Preferably, the noise cancelling soundbar  920  may comprise a processor  960 , a wireless communication module  970 , and a signal preamplifier  980  that operates both the noise cancelling soundbar  920  and the noise cancelling soundbar slave device  921 . The noise cancelling soundbar  920  may receive an audio input signal  915  from a media device  910 , such as a television (TV), smartphone, tablet, or other device capable of playing audio and/or audiovisual media. The audio input signal  915  may be transmitted to the noise cancelling soundbar  920  wirelessly and be received by the wireless communication module  970 . The audio input signal  915  may, alternatively, be transmitted to the noise cancelling soundbar  920  via a wired connection. 
     The audio input signal  915  may be enhanced by the signal preamplifier  980 , and then subsequently transmitted to the one or more loudspeakers  930 ,  931  for the user to hear. The one or more loudspeakers  930 ,  931  may use the (amplified) audio input signal  915  to create a soundbar output audio  937 ,  938 . The soundbar output audio  937 ,  938  may be a faithful reproduction of the audio input signal  915  received from the media device  910 , albeit enhanced and/or amplified. In situations in which the media device  910  includes loudspeakers of its own, the media device  910  loudspeakers may preferably be powered down while the noise cancelling soundbar  920  and noise cancelling soundbar slave device  921  are in use, such that only the noise cancelling soundbar  920  and/or the noise cancelling soundbar slave device  921  are generating audible sounds pertaining to the media that the user is viewing and listening. The volume of the soundbar output audio  937 ,  938  may be controlled by a volume control module  990 , which may allow communication with, for example, a control interface  999 . 
     The one or more loudspeakers  930 ,  931  may be mounted on a rotatable (or otherwise moveable/adjustable) bases  935 ,  1035 , which may be controlled by driver  936 . The rotatable base  935 ,  1035  may be underneath the one or more loudspeakers  930 ,  931  and may be used to adjust the angle of the one or more loudspeakers  930 ,  931 , thereby adjusting the directional output of the soundbar output audio  937 ,  938 . In this manner, the one or more loudspeakers  930  may be adjusted such that the soundbar output audio  937 ,  938  may be precisely aimed (or otherwise directed) at a user&#39;s ears. As a result, a lower volume is required for the soundbar output audio  937 ,  938  to be clearly heard by the user. 
     The noise cancelling soundbar  920  and noise cancelling soundbar slave device  921 , may further comprise one or more microphones  940 ,  941 , which may be used to measure or otherwise determine an ambient noise  927 . The ambient noise  927  may be processed by an active noise cancelling module  975 , to create a negative output audio that may destructively interfere with the ambient noise  927  when combined with the ambient noise  927 . Preferably, the negative output audio may be emitted from the one or more loudspeakers  930 ,  931 , such that the negative output audio largely cancels out any disruption by the ambient noise  927  to a user of the noise cancelling soundbar  920  or noise cancelling soundbar slave device  921 . The one or more microphones  940 ,  941  may be mounted on rotatable (or otherwise moveable/adjustable) bases  935 ,  934 , which may be used to adjust the angle of the one or more microphones  940 ,  941  in order to improve the measurement of ambient noise  927 . The bases  934 ,  935  may be controlled manually or by driver  936 . 
     The noise cancelling soundbar system  900  may be in communication with one or more external (or remote) microphones  945 , that are positioned apart from the noise cancelling soundbars/slaves  920 ,  921 . The external microphone(s)  945  may connect to the noise cancelling soundbar  920  via a wired or wireless interface. The external microphone(s)  945  may be used to measure ambient noise  928  (external ambient noise) not directly near (greater than 2 meters away) the noise cancelling soundbar system. The ambient noise  928  may be processed by an active noise cancelling module  975 , to create a negative output audio which may destructively interfere with the ambient noise  928  when combined with the ambient noise  928 . Preferably, the negative output audio may be emitted from the one or more loudspeakers  930 ,  931 , such that the negative output audio largely cancels out any disruption by the ambient noise  928  to a user of the noise cancelling soundbar system  900 . Preferably, the one or more external microphones  945  may be moveable and repositionable to areas in a room or outside of a room to most advantageously create a negative output audio for destructively cancelling the ambient noise  928 . The external microphones  945  may be connected to moveable and rotatable bases similar to bases  935 ,  1035 . 
     The noise cancelling soundbar system  900  may be connected to one or more control interface  999 , such as a remote control unit, which may be a separate unit or may be mounted into or onto the noise cancelling soundbar  920 , noise cancelling soundbar slave device  921 , into room furnishings (i.e. headboard, nightstand), into or onto a wall, or be used as a separate handheld device. The control interface  999  may connect to the noise cancelling soundbar system  900  via wired or wireless connectivity. The control interface  999  can also be operated and/or adjusted by the media device  910  (i.e., computers, smart phones, control systems). In other embodiments, the control interface  999  is a computer, smart phone, or other control system.
