DETAILED DESCRIPTION
At least certain portions of the text of this disclosure (e.g., claims and/or detailed description and/or drawings as set forth herein) can support various different applications. Although, for sake of convenience and understanding, the detailed description includes section headings that generally track the general concepts as contained in one or more claims, and is not intended to limit the scope of the invention as set forth by each particular claim. It is to be understood that support for the various applications thereby can appear throughout the text and/or drawings, and/or in the claims, irrespective of the section headings.
This disclosure can relate to a variety of embodiments of an audio/sound device 100 that can be utilized by a person; certain of the embodiments are as described in block format with respect to FIG. 1, and at other locations through the disclosure. Certain embodiments at particular applications of the audio/sound device are described, for example, with respect to FIGS. 3, 4, 5, 6, and 7, as well as at other locations through this disclosure. Certain embodiments of the audio/sound device 100 can include an at least one audio source 150, an at least one first sound source 152, and an at least one second sound source 154. The various embodiments of the audio/sound device 100 (as well as the respective sources 150, 152, and 154) as described in this disclosure are intended to be illustrative in nature, but not limiting in scope.
Certain embodiments of the audio/sound device 100 as described with respect to FIG. 1, in block format, can be used for a considerable variety of application involving providing one or more of: relative maintaining, relative reducing, relative diminishing, relative amplification, and other relative processing of one or more of the one or more audio source 150, the one or more first sound source 152, and/or the one or more second sound source 154, as described in this disclosure.
There may be a variety of types or classifications of sounds and/or audio corresponding to the at least one audio source 150, the at least one first sound source 152, and/or the at least one second sound source 154 that can be associated with certain embodiments of the audio/sound device that may be desired or expected by user(s) to be heard during particular periods or for prescribed directions. For instance, the at least one audio source 150 may represent the audio portion that can be heard, or is intended or designed to be heard, during normal operations of the audio/sound device 100. For example, the at least one audio source 150 may include audio for a personal audio device such as a personal computer, laptop, IPOD player, MP3 player, etc. Additionally, the at least one audio source may include speakers, mixers, amplifiers, etc. that may be used for concert systems, music systems, home entertainment units, etc. that may be heard by multiple persons. It may be desired that the at least one audio source be heard during at least some normal operation of certain embodiments of the audio/sound device.
It may also be desired that audio, or other sounds or noises corresponding to the at least one audio source 150, can be diminished, stopped, or reduced with certain embodiments of the audio/sound device 100 during certain durations such as when an emergency vehicle passes, when a loud horn or screeching tires occur, or perhaps even in certain embodiments when a particular noise, sound, or voice (or range thereof) occurs such as when a particular person is talking to the user of the audio/sound device 100. The sound characteristics (or range of characteristics) of the audio and/or sound can be stored or maintained in an audio/sound library 160 as described with respect to FIG. 1. As such, certain embodiments of the audio/sound device 100 as provided within certain embodiments of the audio sound recognizer 162 as described with respect to FIG. 1 can be used to digitize and/or characterize particular sounds, voices, noises, etc. Such sounds, voices, noises, etc., as recognized by certain embodiments of the audio sound recognizer 162, can be characterized based at least in part on the frequency, volume, direction, consistency, or other such characteristics. Such characterization of the sounds, voices, noises, etc. that are obtained by the audio sound recognizer 162 can thereupon be compared to prescribed limits that such as can be contained in certain embodiments of the audio/sound library 160. For example, for a siren or alert sound, a prescribed range of sounds within a range of frequencies, volumes, etc. as obtained by the audio sound recognizer 162 can be compared to, or classified as, sirens, alerts, emergency sounds, etc. that can be maintained, stored, and/or retrieved in certain embodiments of the audio/sound library 160. As such, a sound emanating from a siren or alarm, etc. that can be obtained by the audio sound recognizer 162 of the audio/sound device 100, that falls within the classification of sirens within the audio/sound library 160, can be characterized or recognized as a siren, alarm, alert, etc. by certain embodiments of the audio/sound device 100, and can be recognized and handled appropriately. Certain embodiments of the audio/sound device can also detect and/or indicate a direction of the direction or angle of the siren or other sound with respect to the user, using certain embodiments of directional sound clues, as described in this disclosure with respect to FIG. 2, for example.
If an actual siren is recognized by the audio sound recognizer as corresponding to these siren frequency, volume, and/or other characteristics of an emergency siren, etc., then the sound will be recognized and identified as the siren of the audio/sound library 160; whereupon the audio/sound device might be actuated such as to amplify, maintain, or otherwise emphasize the siren sound as well as provide a directional sound clue as described with respect to FIG. 2 (which may correspond to the at least one first sound source 152) with respect to the at least one second sound source 154 and/or the at least one audio source 150, as described in this disclosure.
Similarly, a voice, or other identifiable noise or sound, could be obtained, digitized, processed, and/or otherwise utilized by certain embodiments of the audio sound recognizer 162, which can thereupon be compared to the respective voice, or other noise or sound range information as may be stored or otherwise maintained in the audio/sound library 160. If the voice corresponds, to the voice range information is included or maintained in the audio sound library 160, then the voice can be amplified, maintained, and/or otherwise emphasized as the first sound source 152 as described in this disclosure. As such, prescribed voices, etc. (that may be characteristically associated with a particular person) that falls within the classification of frequency or other characteristics for a particular person within the audio/sound library should be recognized as the voice of that particular person by certain embodiments of the audio/sound device 100, and handled appropriately by the audio/sound device 100.
Such additional sounds, voices, or noises may be characterized in certain aspects of this disclosure as the at least one first sound source 152, which can, depending on context, represent that noise, voice, or sound that is not produced by the audio/sound device 100 during normal operation, but which the user of the audio/sound device may still have a desire to listen or hear. In certain embodiments of the audio/sound device 100, it may be desired to enhance such as by amplification the at least one first sound source 152 relative to the audio source 150 and/or the at least one second sound source 152. Certain embodiments of the relative emphasis between various sources 150, 152, and/or 154 can take a variety of forms including but not limited to, amplification of the first sound source 150; manufacturing the first sound source 152 as the second sound source 154 and/or the audio source is diminished or cut, etc.
The at least one second sound source 154 can, depending on context, include those noises, sounds, voices, ambient sounds, vehicle noise, white noise, etc. that are not provided by the audio/sound device to which the user of the system may not particularly wish of may to listen, or may decide to limit the presentation thereof. Alternatively the second sound source may obscure and/or distract the first sound source 152 and/or the audio source 150 during normal operation of the audio/sound device 100. Certain aspects of the audio/sound device 100 may thereby be configured to relatively reduce the effects of the at least one second sound source 154, while relatively enhancing the effects of the first sound source 152.
In certain instances the at least one second sound source 154 may thereby include, but not be limited to, ambient noises, extraneous voices, vehicle noises, stray voices, etc. that may otherwise interfere with the ability of the user of the audio/sound device to listen to or hear the at least one audio source 150 and/or the at least one first sound source 152. As such, it may be desired to relatively diminish the volume or other effects of the second sound source 154 relative to the first sound source 152 and/or the audio source 150. Certain embodiments of commercially-available noise cancellation systems, such as are utilized and are commercially available in aircraft, manufacturing applications, as well as other applications where there may be considerable noise, and the noise being cancelled in such commercially available devices may represent a combination of the at least one second sound source 154 and the at least one first sound source; which together may be cancelled in combination by such commercially-available noise cancellation systems.
Another technique that can be used to emphasize certain embodiments of the at least one first sound source 152 with respect to the at least one second sound source 154 and/or the at least one audio source 150 can include delaying and re-presentation of the at least one second sound source 152. For example, a voice can be spoken, a siren or aural alert can recorded and identified, or recognized as, the at least one first sound source 152, the at least one first sound source can be digitized, recorded, and/or delayed; and thereupon the at least one delayed version of the at least one first sound source 152 can be reproduced, represented, or replayed, etc. such as may be selected as being appropriate for certain embodiments of the audio/sound device 100. Such re-presentation of the first sound source 152 can be provided at a time when the at least one second sound source 154 and/or the at least one audio source 150 is diminished, or cut. As such, by representing the first sound source 152 at a substantially even or amplified level as compared to the original level as the at least one second sound source 154 and/or the at least one audio source 150 is diminished will allow the at least one first sound source 150 to be better heard.
In certain embodiments of the audio/sound device 100, the at least one audio source 150 and/or the at least one second sound source 154 can be reduced, muted, and/or cut during the representation of the at least one first sound source 152, thereby further emphasizing the at least one first sound source 152. Certain representations of the at least one first sound source 152 can occur multiple times to further emphasize the first sound source.
Certain embodiments of the audio/sound device 100 may utilize noise cancelling systems (which may include noise cancelling headphones) to reduce ambient noise and thereby allow improved hearing of the at least one audio source 150 and/or the at least one first sound source 152. Certain commercially-available active noise cancellation systems, such as noise-cancelling headphones, can reduce unwanted ambient sounds (i.e., acoustic noise) by means of active noise control. By comparison, certain passive noise cancellation headphones and/or systems can rely at least partially on sound insulative material; acoustic insulative material, and/or shape of the headphone and/or system to limit sound being applied to the user. Certain ones of the active noise cancellation headphones and/or systems can be combined with passive noise cancellation headphones and/or systems.
Essentially, certain active noise cancellation headphones and/or systems (either commercially available or embodiments of the audio/sound device 100) can utilize a microphone positioned nearby the ear of the user to detect noise or sound that can be obtained by the user. Certain active-noise cancellation headphones and/or systems can utilize circuitry (including hardware, firmware, and/or software based on design choice or expediency) to generate an “anti-noise” sinusoidal sound wave having the opposite sinusoidal polarity as the sinusoidal sound wave that can be combined with the detected noise to be applied to the user(s)' ears. The detected noise and/or sound can thereby destructively interfere with the “anti-noise” sinusoidal sound wave, thereby largely cancelling out the noise within the enclosed volume of the headphone. Reducing noise prescribed at the user(s)' ear using certain active noise cancellation headphones and/or systems (either commercially available or embodiments of the audio/sound device 100), makes it possible to hear, detect, and enjoy the audio, sound, voice(s), etc. without raising the volume of the audio/sound device 100 unnecessarily. It can also help limit the volume of the sound, audio, voice, and/or noise being applied to the user in a noisy environment such as a vehicle such as an aircraft, a factory, proximate a noisy machine, etc.
Certain active noise cancellation headphones and/or systems only cancel the lower-frequency portions of the noise; that can depend upon passive noise cancellation techniques (such as ear-cups of headsets) to prevent higher-frequency noise from reaching the interior of the headphone.
This approach benefits the user since the technological demands and/or design of the electronic circuitry are simplified; because of the shorter wavelength of the high-frequency sound, active cancellation is much less effective at higher frequencies. To effectively cancel high frequency components (directed towards at the ear from a number of directions), the sensor and emitter for the cancelling waveform should be as close as practicable to the user's ear(s).
Certain active noise cancellation headphones and/or systems (either commercially available or embodiments of the audio/sound device 100) have several characteristics including but not limited to: a) they consume power, which can be provided by a battery or other power source, b) they may be optimized for sounds that are continuous, such as the noise or hum of an engine, vehicle, or piece of equipment, but may be rather ineffective against rapidly changing audio signals such as speech, alarms, etc.; d) they may introduce additional noise, perhaps in the form of high-frequency hiss; and/or they may pick up and convert stray electromagnetic fields, such as a mobile phone signal, into unwanted noise.
Certain embodiments of the audio/sound device, as described in this disclosure, can considerably reduce the at least one second sound source 154 while maintaining, enhancing, or even amplifying the at least one first sound source 152. Therefore, the sounds of certain embodiments of the at least one second sound source 154 that may be heard by the user of the audio/sound device may be desired to be diminished as much as practicable.
Certain embodiments of the audio/sound device 100 can be configured to allow the user, operator, owner, or other person or automated mechanism to select or determine the frequencies, types, characteristics, and/or other aspects of the at least one first sound source 152 and/or the at least one second sound source 154, and thereby determine which of the sound sources should be relatively diminished, relatively accented, relatively amplified, relatively filtered, and/or have some other suitable relative operation performed thereupon. While the at least one first sound source 152 and the at least one second sound source 154 may appear in FIG. 1 as being presented from outside of the audio/sound device, in certain instances, the sound from either of the sound source(s) 152 or 154 can alternatively originate at least partially outside of the audio/sound device, at least partially internally to the audio/sound device, entirely within the audio/sound device, and/or a combination thereof. Certain embodiments of at least portions of an audio/sound controller 97 can additionally utilize hardware, software, and firmware, as well as mechanical, electromechanical, or other structure(s) to provide an effective interface with the user, owner, or other person, as well as providing some suitable automated or self-control mechanism.
Within this disclosure, certain embodiments of the sound source(s) (which within this disclosure can include, but is not limited to, the at least one first sound source 152 and/or the at least one second sound source 154) can take a variety of forms such as to be capable of performing a variety of functions. For instance, certain embodiments of the sound source(s) can include, but are not limited to, recording, storing, digitizing, accessing, playing, and/or otherwise processing one or more natural or recorded or synthesized voices, noises, and/or sounds made by persons; one or more natural or recorded or synthesized sounds or noises made by objects (e.g., sirens, hazard sounds, machine sounds, buzzers, recorded or synthesized voices, etc.), as well as one or more natural or recorded or synthesized sounds or noises made by animals or things. These embodiments of the sound sources may be digitized, recorded or synthesized, analyzed, or otherwise processed using certain embodiments of such audio conversion, voice conversion, sound conversion, or other similar conversion devices involving but not limited to microphones, recording, computing, signal analyzing processing and/or other similar equipment as generally understood by those skilled in audio technologies in a manner as described with respect to the audio/sound controller 97, as described in this disclosure.
In certain embodiments of the audio/sound device 100 as described in this disclosure, certain embodiments of the at least one first sound source 152 can represent, depending on context, certain sounds, voices, noises, etc. to which the user of the audio/sound device desires to hear or listen. For example, it may be desired for the user of certain embodiments of the audio/sound device 100 to hear or understand the at least one first sound source 152 perhaps even over the at least one audio source 150 and/or the at least one second sound source 154, thereby allowing for the relative emphasis of the at least one first sound source 152 relative to the at least one second sound source 154 and/or the at least one audio source 150.
It should be understood that certain embodiments of the at least one first sound source 152 and the at least one second sound source 154 can each take a variety of forms, but as described relative to this disclosure, both the at least one first sound source 152 and the at least one second sound source 154 can be considered inclusively, depending upon context, as sound sources. Certain embodiments of the sound source(s) can utilize such information, signal, or data transfer mechanisms as may include, but are not limited to, sound data streams, sound signals, or other acoustic computer-based information that can be readily played on an audio system, stored, recalled, transmitted, received, filtered, analyzed, or otherwise processed. The recalling of at least some of the sound sources) in certain embodiments of the audio/sound device 100 can be at least partially controlled by the user(s), and can occur as they occur or are received, or alternately can be automated.
With certain embodiments of an audio/sound device 100, the at least one first sound source 152 can be in some manner combined with the at least one second sound source 154. Such combination of at least some of the sound sources 152 and 154 can take a variety of forms, such as output from the at least one first sound source 152 being mixed, and/or otherwise combined, with output from the at least one second sound source 154. In addition, the at least one first sound source 152 and/or the at least one second sound source 154 can include but are not limited to external noises or sound, ambient noises are sound, etc. that may be allowed to be combined.
In this disclosure, certain embodiments of the at least one audio source 150 can include that portion of the audio/sound device 100 which provides during normal operations the intended audio or sound to the audio/sound device 100. There can be a variety of the at least one audio sources 150, and a variety of applications therefore, as are described in this disclosure. For example, certain embodiments of the audio/sound device 100 can include, but are not limited to, a purely audio device which may be personal, such as an IPOD, MP3 player, a personal computer audio system, (PC), or laptop computer audio system, or certain home audio systems. Certain embodiments of the audio/sound device 100 can be configured to include the speakers, headphones, amplifiers, etc. that can thereby be utilized to provide the audio and/or sound to the one or more people listening to the audio/sound device.
Certain embodiments of the audio/sound device 100 can also provide directional sound clues. Humans rely to a considerable extent on hearing to not only determine a direction from which voices, noises, sounds, etc. are originating from; in addition to the actual contents of the voices, noises, sounds, etc. Within this disclosure, the directional sound clues can indicate, depending on context, which direction from which at least some noise, sound, voices, etc. are originating. Often, the at least one second sound source 154 as well as the at least one audio source 150 can act to hide or confuse the direction of the at least one second sound source relative to the individual. The directional sound clues may be appropriate to determine the orientation of the second sound source 152 relative to the individual. It is understood by those skilled in the audio art that certain conventional sound systems, surround sound systems, personal audio devices, stereo audio devices, headphone devices, etc. can project sound that can appear to one or more users to originate from a variety of locations or angles relative to one or more users. Using similar technology, in a manner understood by those skilled in audio technology, certain embodiments of the audio/sound device can direct the at least one audio source 150 and/or the at least one first sound source 152 to provide at least some directional clues, as described in this disclosure. In the case of voices, the directional sound clue can indicate a direction of the person speaking. In the case of sounds, the directional sound clues can thereby provide a clue as to the direction of the sound in certain embodiments of the audio/sound device. In the case of an emergency vehicle or hazard, the directional sound clues can provide a clue as to the direction of the emergency vehicle or hazard.
The selection of which sounds, noises, voices, etc. that can be characterized as the at least one first sound source 152 as compared with the at least one second sound source 154 may be a design choice, or may be configurable by the user, producer, and/or designer of certain embodiments of the audio/sound device 100. For instance, certain personalized embodiments of the audio/sound device 100 can be configured to allow certain users to input voice samples corresponding to those persons that the user wishes to hear, or have conversation with, into the audio sound library 160 such as can be easily recognized over, for example, crowd voices, ambient noises, and other less significant sounds. It might be expected that parents might input the voices of their children into the audio sound library 160 of the audio/sound device, such that these voices may be emphasized relative to other voices or sounds.
By comparison, certain sirens, alarms, alerts, etc. may be provided by the provider of certain embodiments of the audio/sound device, since certain providers could more fully be able to determine which sounds, generally, fall within emergency sounds, siren sounds, etc. Certain embodiments of such emergency, alert, siren, or other such sounds may be characterized and maintained within certain embodiments of the audio sound library, and compared to the sound of the siren, emergency, alert, etc. that can be obtained by the certain embodiments of the audio sound recognizer 162 as described with respect to FIG. 1.
Certain embodiments of a directional sound clue mechanism 820 as described with respect to FIG. 2, can provide directional clues as to the position, or angle, of the at least first sounds source with respect to the user. Users of conventional sound or audio devices such as IPODS, car radios, CD players, surround sound systems, etc. can have a variety of directional sound clues diminished or obscured, especially if the audio, sound, or noise is particularly loud. As such, can provide an indication to users of the audio/sound device 100, as to a direction from which the at least one first sound source 152 originated.
Certain embodiments of the directional sound clue mechanism 820 can include a multi-directional audio presentation device 822, that can present sound, audio, and/or noise in a direction or angle as described. As such, the at least one first sound source 152 should, appear to originate from a particular direction corresponding to the original sound, voice, etc., even if the first sound source is filtered, amplified, modified, and/or otherwise processed.
There may be a considerable variety of the audio/sound device 100 that can operate or are structured in a manner similar to as described with respect to FIG. 1, a number of which are now described. Certain embodiments of the audio/sound device 100 can be utilized as described with respect to FIGS. 3, 4, 5, 6, and/or 7, as well as at other locations in this disclosure. Certain embodiments of the audio/sound device 100 can be usable to provide audio to one or more person(s), and in certain embodiments groups of persons, at least partially using one or more embodiments of the selective sound/audio provider 102. Within these embodiments of the audio/sound device 100 as described with respect to FIGS. 3, 4, 5, 6, and/or 7, the location of the at least one audio source 150, the at least one first sound source 152, and/or the at least one second sound source 154 may not be illustrated, but are intended to be determinable according to the operation of the audio/sound device 100.
For instance, with an embodiment of the audio/sound device 100 that can be configured as a personal audio device such as an IPOD, MP3 player, transistor radio, etc., as described with respect to FIG. 3, it is envisioned that the at least one audio source(s) 150 can include the audio that can normally be provided by the audio/sound device 100. By comparison, the at least one first sound source 152 can include, but may not be limited to, those sounds, noises, voices, etc. that originate from outside of the audio/sound device 100 that the user of the audio/sound device may wish to hear, such as sirens, alarms, certain voices, etc. As such, a user walking down the street, in the office, in the home, or in other such locations can listen to particular important noises (e.g., sirens, alerts, voices, etc.) or voices, while they do not have to listen to other noises, voices, etc. Additionally, the at least one second sound source can include, but may not be limited to, those noises, sounds, voices, etc. outside of the audio/sound device 100 that the user of the audio/sound device may not wish to hear.
As described with respect to FIG. 3, certain embodiments of the audio/sound device 100 can be configured as a personal audio/sound device 150 that can provide at least one audio source 150 that can typically be used by a single user, but in certain instances may be used by more than one person. Examples of the personal audio/sound device 150 at least one audio source 150 can include, but is not limited to, an devices that may appear as, or may include the at least one audio source 150 that can operate similar to, for example, the audio portions of IPODs, personalized audio players, personalized radios, an MP3 player (which are commercially available), etc., such as to include a headphone, earplug, and/or other audio providing system that can enable at least one user to listen to audio, sounds, music, noises, etc.
Certain embodiments of the audio/sound device 100, may thereby be configured as a personal device, and can thereby as with other embodiments of the audio/sound device 150 limit the transmission of the second sound source 154 and/or the audio source 150 relative to the first sound source 152, as described with respect to FIG. 1 as well as at other locations in this disclosure. With certain embodiments of the personalized audio/sound device 100, the user can configure certain of those sounds of the at least one first sound source 152 that the user wishes to have emphasized relative to the at least one second sound source 154 and/or the at least one audio source 150, such as by recording voices of friends, family, etc. that can be included in the audio sound library 160 as described with respect to FIG. 1. With certain embodiments of the personalized audio/sound device 100, the device provider, producer, or administrator can configure certain of those sounds of the at least one first sound source 152 that should be emphasized relative to the at least one second sound source 154 and/or the at least one audio source 150, such as by determining those particular or range of sounds, noises, voices, etc. that can be characterized as falling within the at least one first sound source, as described in this disclosure. As such, certain individual audio listeners might utilize certain embodiments of the selective sound/audio provider 102.
Certain embodiments of the audio/sound device 100 can provide a variety of audio sources and/or sound sources 150, 152, and/or 154 (as described with respect to FIG. 1) to a number of uses such as with a concert, a speech, a speaker phone, a speaker-based audio system, and/or other multiple user audio/sound system as described with respect to FIG. 4. With certain group embodiments of the audio/sound device 100, it is still possible to provide particular individualized settings for the members of the group members. For example, voices of certain children, spouses, friends, etc. who may get lost in crowds, etc., may have their voices recorded and maintained in the audio sound library 160 of certain embodiments of the audio/sound device 100, and if their voice is raised to a particular level, then they may be emphasized above the volume of the other group members.
Additionally, certain performers, speakers, musical instruments, etc., may have their voices, noises, sounds, etc. characterized as a first sound source 152, and such voices, noises, sounds, etc. can thereupon be amplified, maintained, or otherwise emphasized above other voices, noises, sounds, etc. During a live concert, for example, the performers and their instruments may be classified as the first sound source(s), and certain group embodiments of the audio/sound device 100 can relatively filter out, cancel, reduce the other noises of the audience or stage, and thereupon relatively emphasize (either through amplification or not) the at least one first sound source 152 corresponding to the voices or sounds of the performers, speakers, instruments, etc. Additionally, in a live concert or speech, certain group-based embodiments of the audio/sound device can be configured to reduce amplified or normal voices, noises, sounds, etc. corresponding to the audio sound source(s) 150 and/or the second sound source(s) 154 in those instances where an emergency sound, voice, noise, siren, alarm, etc. is detected by the audio sound recognizer 162 as described with respect to FIG. 1.
Certain embodiments of the audio/sound device 150 may thereby be utilized by one person, or a group of people in such environments as the home, the office, in concerts, with speeches, outdoors, in which audio and/or sound is being projected to one or more people, or groups of people. With those audio/sound device(s) 150 that are being utilized by a group of people, the volume, contacts, or other characteristics of the sound, voices, noises, etc. that can be characterized as the at least one first sound source 152, such as can be maintained in, retrieved from, or otherwise utilized by the audio sound library 160, can often selected by one or more people. Often a number of users of certain group embodiments of the audio/sound device 100 may have relatively little input into changing the sound characteristics contained in the audio sound library 160 of the audio/sound device. With certain embodiments of audio/sound device(s) 150 that can be used by groups of users, at least some of the users may be provided with headphones, earplugs, or a controllable gradient of sound and/or audio that may be distinctly controlled such as to provide for different embodiments of the at least one first sound source 152, at least partially by each particular user.
As described with respect to FIG. 4, certain embodiments of the audio/sound device 100 can thereby be configured as a group audio/source, such as to provide sound for a group of people such as in concerts, speeches, events, etc. As such, certain group members might utilize certain individualized embodiments of the selective sound/audio provider 102. With such embodiments of the audio/sound device 100 such as may be usable by groups of people, etc., the audio/sound device 100 can be configured to include the speakers and/or amplifiers, and/or the associated component, which can be utilized to provide audio and/or sound to the groups of people listening to the audio/sound device.
As described with respect to FIG. 5, certain embodiments of the audio/sound device 100 can be configured as at least on audio source which can be used by users within a vehicle (particularly noisy ones) such as a car, truck, bus, train, aircraft, ship, boat, military vehicle; etc. Certain embodiments of the audio/sound device 100 can thereby be situated in such vehicle. As such, certain drivers, operators, or occupants of the vehicle might utilize certain embodiments of the selective sound/audio provider 102. There may be a variety of sounds or noises that are peculiar to vehicle traffic, while certain embodiments of the audio/sound device can experience sounds or noises that are common to other types of audio sound device(s) (e.g., voices of people speaking).
With certain vehicular-based audio/sound devices 100, certain individuals could have their voices characterized as at least one first sound source 152. For example, a large ship or aircraft may be equipped with certain embodiments of the audio/sound device 100. A captain or officer on a large ship might thereupon have their voice characterized as the at least one first sound source 152, and such as to be emphasized above the ambient sound, the at least one audio source 150, and/or the at least one second sound source 154. Such amplification of the captain's of officer's voice may be presented at prescribed locations throughout the ship regardless of the physical location of the captain or officer. Certain embodiments of audio, sound, voices, etc. may be shared between multiple devices, such as may be similar to as described with respect to the following audio sharing application entitled: Audio Sharing, U.S. application Ser. No. 11/210,284 (incorporated herein by reference in its entirety). In addition, certain other people on the vehicle such as the ship of aircraft may have their voices presented to other locations regardless of their location based, at least in part, on having their voices characterized as first sound source(s) as maintained in certain embodiments of the audio sound library 160, as described with respect to FIG. 1.
FIG. 7 shows another embodiment of the audio/sound device 100 that is configured to be applied to industrial (particularly) environments. It is generally understood that a variety of industries can be quite noisy, and as such can utilize a variety of noise cancellation technologies. For instance, such industrial locations as factories, fabrication, construction, power generation, aircraft loading or unloading, riveting, robotics, turbines, road working equipment, etc. can provide a considerable amount of noise by their very operation. While FIG. 7 illustrates a user utilizing certain embodiments of audio/sound device 100 as described with respect to FIG. 1 such as earplugs, earmuffs, etc, who is positioned in close proximity to a power generation device (e.g., a jet engine), it should be understood that such audio/sound devices can be applied to users position in other industrial environments.
It may be is difficult to communicate with others within noisy areas (industrial, commercial, concerts, etc.) as a result of the environmental noise. To thereby limit the amount of noise, certain embodiments of the audio/sound device(s) 100 can thereby be configured as noise cancelling devices (headphones) by which the user can reduce some of the noise applied thereto. In a similar manner as the voice of the captain or officer of the ship being emphasized relative to other voices; so can certain foremen, subordinates, co-workers, or other persons have their voices characterized as at least one first sound source 152 in one or more audio/sound device(s) 100, and thereby emphasize their voice relative to others or relative to the ambient or other noises or sounds.
Additionally, it may be dangerous for certain workers or other persons to be situated at various locations within the work area. As such, certain alarms, alerts, hazards, etc. can be provided as first sound source(s), such as to be relatively emphasized, amplified, maintained, etc. relative to other sounds that can be included in the at least one second sound source(s) 154 and/or at least one audio source(s) 150. As such, users of certain embodiments of the audio/sound source(s) can receive enhanced hazard, emergency, and other warnings in their workplace and/or other noisy environments. Certain embodiments of the audio/sound device can also provide 1-way or 2-way radio communication (e.g., similar to a walky-talky, cellular telephone, computer-device, communication device, etc.), and certain ones of such communications can be characterized as the at least one audio source 150, the at least one first audio source 152, and/or the at least one second audio source 154 as described in this disclosure.
Certain embodiments of vehicles can provide a considerable amount of noise from such sources as road noise, wind, weather, music, audio/radio, hiss or distortions, etc. and such undesirable or secondary noises could be characterized as certain embodiments of the at least one second sound source(s) 154 as described with respect to FIG. A1. Certain vehicular based embodiments of the audio/sound device could be configured to lessen the impact of such additional noises while allowing the users/drivers/operators, etc. to detect certain emergency vehicle sirens or noises, desired voices, etc. As such, certain embodiments of the audio/sound device can be configured to utilize or provide noise cancellation characteristics, similar to commercially available noise cancellation headphones.
Certain vehicular-based embodiments of the audio/sound device 100 can also enhance directional sound clues. For example, drives of cars, truck, ships, aircraft can each rely on location of outside sirens, yells, horns, other vehicle noises, etc. (e.g. first sound source) such as may be difficult to hear over the ambient vehicle noise (e.g. second sound source) and/or the audio source (e.g. car or vehicle radio, etc.). Such directional sound clues are especially significant with vehicle audio/sound devices 100, since detecting sound from particular directions may affect how the vehicle is operable.
Other non-vehicular embodiments of the audio/sound device 100 can also be configured to provide directional sound clues. Consider that conventional personal or group sound systems may be played so loudly as to obscure directions of secondary audio. Certain embodiments of the audio/sound device(s) can allow the users to obtain such directional clues either by limiting external sounds or alternately by enhancing some indication as to which direction from which certain sounds, voices, machines, horns etc. (or other embodiments of the first said source(s) 152 originated.
In addition, certain embodiments of the audio/sound device 100 can be utilized as a portion of video systems, television systems, graphic systems, computer systems or other systems. For example, as described with respect to FIG. 6, certain embodiments of the audio/sound device 100 can be configured as an audio/video source such as to provide visual information in both audio and video formats (which may be typically expected to be synchronized). For example, certain embodiments of the audio/sound device 100 can include, but not limited to, a portion of such systems as: a television system, a display system (e.g., a liquid crystal display (LCD) or plasma display), a computer-based system, a personal display assistant (PDA) system, etc., a vehicular system (e.g., in a truck, car, aircraft, railroad, bus, ship, military vehicle, etc.), a communication system, a controller-based system, etc. Certain embodiments of the audio/sound device 100 can thereby be utilized as portions of the systems may interface with the other portions of the systems in a variety of manners. Consider that certain embodiments of the audio/sound device 100 integrated in the television, display, or computer system as described with respect to FIG. 6 could reduce, cut, stop, or mute its audio source (output) if such an at least one first sound source 152 as an emergency sound was detected such as a siren or alert. In addition, if certain persons have their voice characterized as first sound source(s), as they speak, certain embodiments of the audio/sound device can relatively diminish the audio (or relatively enhance their voices).
With certain system embodiments of the audio/sound device that include a display portion as described with respect to FIG. 6, if operation of the audio source 150 (e.g., audio output) is muted or cease, then the corresponding video, television, display, etc. can also be ceased or frozen. In this manner, a speaker having their voice being identified as the first sound source will not act to diminish or cut the audio of certain embodiments of the audio/sound device 100 each time they talk; but may instead cause the program to freeze or stop, and the audio and video may continue together when the discussion ends.
As described in flow chart form with respect to FIGS. 8 and 9, certain embodiments of the audio/sound device can utilize at least one or more from two options such as to emphasize the at least one first sound source 152 relative to the at least one second sound source 154 and/or the at least one audio source 150. In certain embodiments, as described with respect to operation 650 of FIG. 8, the emphasizing of the at least one first sound source 152 can result by at least partially limiting/reducing the at least one second sound source 154 and/or the at least one audio source 150 relative to the at least one audio source, such as by filtering the sound relative to the second interruptive (audible) at least one audio source.
In other embodiments, the emphasizing of the at least one first sound source 152 as described with respect to operation 750 as described with respect to FIG. 9, can result by at least partially amplifying the at least one first sound source relative to the at least one second sound source 154 and/or the at least one audio source 150, and in certain instances that at least one first sound source 152 may be mixed or combined with the at least one second sound source 154 or the at least one audio source 150.
Certain embodiments of the audio/sound device 100 can thereby be configured such as to include content filters, such as to allow differentiation of one or more of the at least one first sound source 152, the at least one second sound source 154, and/or the at least one audio source 150. In certain instances, the one or more of the at least one first sound source 152, the at least one second sound source 154, and/or the at least one audio source 150 can be individually sampled, digitized, filtered, enhanced, amplified, sustained, or otherwise suitably processed. Certain embodiments of the audio/sound device can thereby be considered to include content-based filters, e.g., that can be configured to operate the at least one first sound source 152, the at least one second sound source 154, and/or the at least one audio source 150 at certain prescribed or controllable levels. As such, certain embodiments of the audio/sound device 100 can be configured to allow some content in but not other content.
Certain embodiments of the audio/sound device 100 can be configured to operate other than to emphasize the at least one first sound source 152 relative to the at least one second sound source 154 and/or the at least one audio source 150. For instance, certain embodiments of the audio/sound device 100 can be configured to de-emphasize or filter out the at least one first sound source 152 relative to the at least one second sound source 154 and/or the at least one audio source 150. Consider that certain embodiments of the audio/sound device 100 could be programmed to hear certain voices or sounds (such as from the at least one first sound source 152), amplify those voices sounds, and transmit them (or representative versions thereof) into the listened-to audio stream. One example can include certain users of the audio sound device 100 that are programmed to recognize the voice of a person or noise that is not desired to listen to, and effectively filter the voice or sound; such as with use of a volume increase of the at least one audio source 150 relative to the at least one first sound source.
Certain embodiments of the audio/sound device 100 can be configured to interface with the phone. For instance, certain embodiments of the audio/sound device 100 incorporating a phone can “hear” the phone (such as by auditory or electronic signaling means such as via a network connection, and out-of band communications), and thereafter diminish or in extreme instances turn off the phone, and allows the at least one first sound source 152, that may be configured as real world sound, to pass through as described with respect to FIG. 9. Alternatively, certain embodiments of the audio/sound device including the phone can be configured to boost the at least one first sound source 152 being presented to the user, while temporarily reducing noise from the phone.
Consider that certain embodiments of the audio/sound device could be considered as a selective enhancement to listening device that amplifies sounds or voices with certain prescribed characteristics, and relatively de-emphasized of certain voices, sounds, noises, etc. with other characteristics. Such characteristics can be based on the frequency, volume, direction, of other characteristic of the voices, noises, sounds, etc. As such, certain embodiments of the audio/sound device 100 should be considered to be content savvy and responsive some input from the user, or in certain instances some pre-configuration by others than the user.
Certain embodiments of the audio/sound device 100 can utilize headphones, ear cups, earplugs, or other devices that can provide sound directly to one or more users. Certain embodiments of the audio/sound device 100 that include headphones or earplugs can provide logic and processing capabilities as associated with the audio/sound controller 97 either in the audio/sound device 100, in the headphones, or in a combination thereof.
Certain embodiments of the audio/sound device may be configured to provide for mixing of audio signals and/or sound signals. Certain embodiments of the audio/sound device 100 can thereby be configured to allow the at least one first sound source 152 to be emphasized or deemphasized relative to the at least one second sound source 154 and/or the at least one audio source 150. As such, the at least one first sound source 152 may thereby be allowed to be at least partially listened to, or alternately may be desired not to listen to or to filter out.
Certain of the technologies utilized by certain embodiments of the audio/sound device 100 can be configured with similar processes or mechanisms as with conventional noise canceling devices or systems. Certain conventional noise canceling devices or systems, which are commercially available, may be used in such applications where it is desired to actively filter certain noises out such as with aviation, industrial equipment, road working, etc. Such companies as Bose, David Clark, Softcomm, among others, design and provide commercially available active noise canceling systems (which may be configured to represent certain commercially available versions or embodiments of the audio/sound device 100). Certain embodiments of the audio/sound device 100 can be configured as a noise cancelling system, as described in this disclosure. With such embodiments of the audio/sound device 100 that are configured as noise canceling systems, noise canceling headphones, noise canceling speakers, etc.
Certain embodiments of the audio/sound device 100, as described in this disclosure, can thereby be configured to limit any excessive noise, sound, etc. that can be classified as originating as the at least one second sound source 154, in a similar manner as conventional noise cancellation systems and devices can cancel or limit noise, sound, etc.
With certain embodiments of the audio/sound device 100, the at least one first sound source 152 can be modified such as by being amplified, sustained, etc. Examples of the modification of the at least one first sound source can include but are not limited to: filtering, amplifying, maintaining, sustaining, processing, etc. Such modification can be based, for example, at least in part on at least some specific spectrum of information, specific frequencies, specific spectral content, specific recognition-based, etc., of the at least one first sound source 152 relative to the at least one second sound source 154 and/or the at least one audio source. By comparison, certain embodiments of the audio/sound device 100, as described in this disclosure, can be configured to allow or enhance noise, sound, etc. that can be classified as originating as the at least one first sound source 152. Certain embodiments of the at least one first sound source 152 can be heard above the diminished at least one second sound source 154 during normal operation of the audio/sound device 100.
Such diminishing of the at least one second sound source relative 154 to the at least one first sound source 152 (or alternatively the amplification of the at least one first sound source relative to the at least one second sound source) can be especially desirable if the at least one first sound source 152 includes a voice of a person with whom the person using the audio/sound device 100 is attempting to communicate. The diminishing of the at least one second sound source 154 relative to the at least one first sound source 152 (or alternatively the amplification of the at least one first sound source relative to the at least one second sound source) can also be desirable if the at least one first sound source includes an emergency signal, noise, voice, etc. Therefore, in general, the diminishing of the at least one second sound source relative 154 to the at least one first sound source 152 (or alternatively the amplification of the at least one first sound source relative to the at least one second sound source) can also be desirable if the at least one first sound source corresponds to some desired sound to hear.
There can be a variety of mechanisms and/or techniques by which the at least one first sound source 152 can be enhanced, amplified, or maintained relative to the at least one second sound source 154. For example, a voice corresponding to the at least one first sound source can be digitalized, such as by using a microphone, an analog to digital converter, etc.
